Major General Eric B. Schoomaker
Commanding General
U.S. Army Medical Research and
Materiel Command and Fort Detrick

Major General Eric B. Schoomaker graduated from the University of Michigan in Ann Arbor, Mich., was commissioned a second lieutenant as a Distinguished Military Graduate, and was awarded a Bachelor of Science degree. He received his medical degree from the University of Michigan Medical School in 1975 and completed his Ph.D. in human genetics in 1979.
 
He completed his internship and residency in internal medicine at Duke University Medical Center in Durham, N.C., from 1976 to 1978, followed by a fellowship in hematology at Duke University Medical Center in 1979. He is certified by the American Board of Internal Medicine in both internal medicine and hematology. His military education includes completion of the combat care casualty course, medical management of chemical casualty care course, AMEDD officer advanced course, Command and General Staff College and the U.S. Army War College.
 
From 1979 to 1982 Schoomaker was a research hematologist at Walter Reed Army Institute of Research. He served as assistant chief and program director, Department of Medicine, Walter Reed Army Medical Center, 1982-1988; medical consultant to headquarters, 7th Medical Command, Heidelberg, Germany, 1988- 1990; deputy commander for clinical services, Landstuhl Army Regional Medical Center, Landstuhl, Germany, 1990-1992; chief and program director, Department of Medicine and director of primary care, Madigan Army Medical Center, Tacoma, Wash., 1992- 1995; director of medical education for the Office of the Surgeon General/HQ USAMEDCOM conducting a split operation between Washington, DC, and Fort Sam Houston, Texas, 1995-1997; and director of clinical operations at the HQ USAMEDCOM, February to July 1997. From July 1997 to July 1999, he commanded the USA MEDDAC (Evans Army Community Hospital) at Fort Carson, Colo. He attended the U.S. Army War College in Carlisle Barracks, Pa., from 1999 to 2000 followed by assignments as the command surgeon for the U.S. Army Forces Command (FORSCOM) from July 2000 to March 2001, and commander of the 30th Medical Brigade headquartered in Heidelberg, from April 2001 to June 2002. Prior to his current assignment as commanding general of the U.S. Army Medical Research and Materiel Command and Fort Detrick, Md., he was commanding general of the Southeast Regional Medical Command/Dwight David Eisenhower Army Medical Center from June 2002 to June 2005.
 
In August 2002, the Army Surgeon General appointed Schoomaker to the position of Chief of the Army Medical Corps.
 
His awards and decorations include the Distinguished Service Medal, the Legion of Merit with four oak leaf clusters, the Meritorious Service Medal with two oak leaf clusters, the Joint Service Commendation Medal, the Army Commendation Medal, the Army Achievement Medal and the Humanitarian Service Medal. He has been honored with the Order of Military Medical Merit and the “A” Proficiency Designator and holds the Expert Field Medical Badge.
 
Interviewed By MMT Editor Jeff McKaughan
 
Q: To get things started, can you give me a little background on MRMC and how it serves military health care?
 
A: We’re about translating concepts and doctrine into products that we put into the cargo pockets of our soldiers. We’re really judged, if you will, not only by the taxpayer but by the soldier, sailor, airman, Marine or Coast Guardsman who count on us to help protect their health and care for them if they are injured or become ill.
 
We really are about medical solutions. The solutions in many cases are final products—like bandages, tourniquets, vaccines and drugs—but they’re also about the expertise that we provide. One of our most important products recently is an orientation, a way of thinking about psychological stress—how it has affected deployed warriors and their families and how we can reorganize our thinking about their restoration and, if necessary, their care. The products of that program, quite frankly, are nothing more than a couple of trifolds and the training of leaders, but it’s the orientation and thinking that’s important.
 
In the military health care system, there’s been a real shift in moving away from just the delivery of health care for combatants and family members who are injured toward preventive medicine and toward timeliness and precision when health care is required. The command is very active in providing the enabling tools— whether they’re information technology, vaccines, or devices at the point of injury—that are part of the transformation of the military health care system. We’ve moved away from pure intervention to health promotion and preventive medicine.
 
Q: Has there been a need to transform the organizational structure of the command to meet the changes in environment and operational tempo?
 
A: All organizations are under pressure to be more agile and responsive to dynamic world situations and emerging threats. We’re always looking at ways to be more effective in engaging with partners and customers to take concepts to realized products.
 
This is a team sport! I would have to say that MRMC organizationally is much less into rearranging the wiring diagrams and organization charts and far more into the business of better synchronization and coordination internally and with external partners. I see this happening in several different ways. We’re coordinating and synchronizing the work of multiple laboratories and multiple agencies that conduct research and develop medical products with a goal of getting products into advanced development and out to the warfighter.
 
We have a superb relationship— a close collaborative and cooperative partnership— with the laboratories and materiel development centers of Major General Roger Nadeau’s Research, Development and Engineering Command and the Army Materiel Command. For every product that requires medical input or regulatory approval, we are there to work closely with our Army materiel developers.
 
We’re also coordinating across interagency boundaries with the Department of Homeland Security, the Department of Health and Human Services—including the National Institute of Allergy and Infectious Diseases and the Centers for Disease Control and Prevention—the Department of Agriculture and other non-DoD federal agencies. All of these non-DoD agencies and departments have expertise that may help us provide solutions for the warfighter.
 
A tangile, visible example of this is the National Interagency Biodefense Campus at Fort Detrick. This partnership among DHS, the CDC, NIAID and USDA is building a large and closely interactive set of research and development partnerships. The campus has gone from concept to its first buildings in less than three years. Two laboratories—NIAID’s and DHS’s—are currently under construction. The campus is also using the Army’s concept of enhanced use leases to provide conference space for the campus as well as utilities. The National Cancer Institute-Frederick, although not a partner in the campus, is contributing biotechnology expertise and support for those collaborative projects with which they can assist. It’s a clear example of the importance of interagency partnerships that will provide protection for combatants while also enhancing protection for the American public from biological threats and emerging infectious diseases.
 
We’re trying to do a better job of coordinating the spectrum for requirements- based approaches so we can provide solutions to enduring and rather resistant threats to the health of the warfighter, for example, with infectious diseases and combat care. We’re also very good at looking at emerging technologies to see how we can take advantage of them. For example, the Telemedicine and Advanced Technology Research Center was able to exploit the Battlefield Medical Information System-Telemedicine— the BMIST—which is a handheld PDA-like device that arose as a technical solution to solve a problem: the requirement for electronic medical records during deployment. It doesn’t solve all of the electronic health record problem, but it has become a portion of a larger, overarching enterprise solution. We were able to get a product out there that has been a real step forward in realizing that enterprise solution.
 
Q: How will the BRAC realignments affect MRMC?
 
A: From the science and engineering standpoint, there were six centers of excellence that were created as a result of the BRAC recommendations. MRMC was involved in five of them: the Joint Centers of Excellence for Chemical Defense, Biological Defense, Medical Research and Development and Acquisition, Infectious Diseases, and Battlefield Health and Trauma Research. So unequivocally, MRMC is affected by the recommendations. In the spirit of base realignment and closure, what it intends to do in the science community is to enable and co-locate like functions to better synchronize collaborations across the three services and prevent redundancies that harm the mission we’re given.
 
My predecessor, Major General Lester Martinez-Lopez had a slogan that I’ve kept: ‘duplication by design not default.’ I think the intent of base realignment and closure is exactly that.
 
I think we’re also mindful that multifunctional and multidisciplinary research arises sometimes out of necessity. Universities spring from colleges because of the need to get a broader perspective on a problem. To some degree some of the mixed functions that occur right now in the labs that are being realigned—like the biological defense research that will move to USAMRIID or trauma research at the Walter Reed Army Institute of Research that’s moving to the Institute of Surgical Research in San Antonio—they may have grown because they met a need over time.
 
We will fully execute the commission’s recommendations, but I want to sow the seed that what we’ve arrived at right now under BRAC might look like a good idea but, over time, may make our researchers less effective. Some of the best ideas in science and technology happen when people from different disciplines have a cup of coffee and share their problems and find out they have common solutions, and I’d hate to lose that.
 
Q: What role does MRMC play in coordinating research with civilian counterparts to avoid duplicating work and funding on similar projects? Do you partner with any non-DoD facilities and in general how do you stay current with R&D in the civilian community?
 
A: We’re very much involved in collaborating and synchronizing elements of MRMC with our service partners, industry and academia to arrive at solutions for the warfighter. The people responsible for keeping abreast of all those opportunities are our research area directors— for military infectious diseases, combat casualty care, military operational medicine and chemical and biological defense. I lean heavily on this team, headed by our principal assistant for science and technology, Dr. Frazier Glenn, to stay current on who does the best science. They are the portfolio managers for what’s happening in the command and academia. Our laboratory commanders are experts in what’s happening in the realm of their laboratories, but they also keep up on opportunities to partner with industry, other services and academia to apply resources to whomever can get the work done most effectively.
 
The Telemedicine and Advanced Technology Research Center is always performing tech watch. It might not be always for every requirement we have for the warfighter, but they may be able to identify a new and emerging technology that the command can take from proof of concept to fielded solution.
 
Q: Will fiscal year 07 funding meet all your plans for projects?
 
A: It’s clear we won’t have enough money to meet all of our plans, but that’s why partnering is so important to the command. One of our core competencies is our ability to market our interests to academia, interagency and industry partners and leverage their funding to take products through advanced development for our customers.
 
Q: Are there any topics that you are focusing on now more so than others? Where do you see the greatest need for medical care advancement?
 
A: The military, in general, is reaping the benefits of applying information systems and knowledge networks in the conduct of war. It’s a fact that the Army is substituting knowledge for mass on the battlefield. Medical care in the 21st century is a very similar information-centered battle. In promoting health and providing health care, we have created a net-centric knowledge base on the battlefield and we are “substituting knowledge for mass.” From the medic to the first responder to higher echelons, the medical footprint has been reduced across space and time with advanced information systems.
 
We’re also optimizing human performance. Our researchers at the U.S. Army Research Institute of Environmental Medicine and the Walter Reed Army Institute of Research and its OCONUS labs are looking at how extremes in environment—like temperature, altitude, sleep deprivation and emotional and mental stress—affect the warfighter. That’s been a real important piece of research for the warfighter.
 
Thirdly, we’re advancing the care of severely injured soldiers and the victims of trauma. Wars have obvious, regrettable aspects: the carnage of battle. We’re making sure we take advantage of the opportunity to advance the care of soldiers, sailors, airmen, Marines and the Coast Guard by harvesting, in real time, lessons to help provide information and products to help combat lifesavers, medics, nurses and physicians.
 
A very busy trauma center in the United States sees as many cases in one year as our hospitals in Iraq see in one month. We’re taking this opportunity to learn as much as we can, as fast as we can, to help the warfighter and care providers. Just as the Army is taking full advantage to change its tactics, techniques and procedures to fight smarter and better, we’re applying the essential features of good science and good analysis by using tools like the Joint Theater Trauma Registry, a database that carefully monitors care from the point of injury through the forward surgical teams and combat support hospitals to rehabilitation centers in the States. We’re going to let evidence drive the decisions about what materiel works best and what organizational structure to deliver care works best.
 
Q: Is there much competition for the skilled and experienced scientists and engineers who are crucial for your work? What are some of the tools and resources you have to maintain your staff and attract new and bright people to you team?
 
A: Everybody in academia, as well as the government and industry, is competing for a shrinking pool of highly qualified people. We’re both a research and medical logistics command, so we’re not just recruiting scientists. Our various mission activities now add up to $1.6 billion and 38,000 business transactions annually, so we need contracting officers. We also need people who have experience with regulatory affairs and the acquisition process because we focus on the lifecycle management of products.
 
The U.S. Army Medical Acquisition Activity, as well as USAMRIID, both offer summer internships to give students an opportunity to work with the command. We also partner with the local academic communities—from elementary schools to universities— through our Gains in the Education of Math and Science, or GEMS, program. The program offers school-aged children a chance to spend a week of their summers working in a lab. The program is led by college-aged students who serve as near-peer mentors for the children to foster a love a science and possibly future careers as researchers or assistants.
 
We partner with industry as well, especially small businesses to help them realize their opportunities to partner with us as future contractors to further our science goals.
 
Q: How user friendly is MRMC for large and small companies to either participate in the bidding process for existing programs and separately to showcase their latest product or technology that they think will fill a need you have?
 
A: In the final analysis it’s for the companies who want to participate with us to tell us how easy or difficult it is to work with us! We certainly make every effort to develop partnerships where it’s profitable for them and us. We have small business partnerships with veterans-owned and disabled veterans-owned businesses. Here at Fort Detrick we have the Fort Detrick Business Development Office that has created a single portal of entry for the entire installation for any businesses who want to work with us. Those businesses have visibility of upcoming contracts and have an opportunity to participate in workshops and get personalized support from that office. Bill Howell, my deputy for acquisition, is always looking at companies to partner with, and Jerome Maltsby and Archie Cardwell have gone out of their way to reach potential partners in small businesses.
 
Q: What do you consider MRMC’s success stories within the past few years?
 
A: We have many success stories. People are most familiar with our products: devices, drugs and vaccines that we have fielded or are in the process of improving. It’s important to note, though, that MRMC is important to the military health care system for its expertise and its intellectual orientation in solving problems. Trauma care, to the command, is not just about providing devices. It’s about how we think about casualties: what care to provide at each echelon of care and how to organize care.
 
One of MRMC’s greatest success stories is with the behavioral health support we’ve provided. As I said at the beginning, though the products are information on trifolds and DVDs, what’s important are the intellectual framework and the approach that’s been taken toward combatants and ensuring emerging symptoms are rapidly identified. Those initiatives have concentrated on thinking about the soldiers who are serving in defense of the country and ensuring they are fully focused. And once they are ready to return to civilian life, we want healthy, fully capable citizens and intact, resilient families.
 
As for products, one of our success stories is the improved first aid kit. It’s the first real modification of the first aid kit since the Korean War. The Army Combat Helmet is providing enhanced protection for the warfighters. The HemCon or chitosan dressing is a great example of being able to go from concept to fielding to the medic and combat lifesaver in the theater of operations in less than two years because we were able to expedite its approval with the Food and Drug Administration. The Combat Application Tourniquet is another example of how the command has made a difference. The civilian medical community hadn’t felt that tourniquets offered an advantage, but we found that they’ve been lifesaving against the most common cause of death, battlefield hemorrhage. The need for the hypothermia prevention kit came out of data collected in the Joint Theater Combat Registry that said the theater needed a device to maintain a casualty’s body temperature because that was a predictor of survival. The BMIST, which I talked about earlier, is also a success story.
 
It’s a real source of pride for all of us that in the past three years, the MRMC has claimed six of the Army’s 30 greatest inventions: the Golden Hour Blood Box, the Virgil Chest Tube Insertion Simulator, the BMIST, the Electronic Information Carrier, the chitosan bandage and the Combat Application Tourniquet. That’s quite an achievement: 20 percent of the Army’s greatest inventions from the MRMC!
 
In the medical logistics arena, we have effected a very successful partnership with the Defense Logistics Agency that permits us to leverage the medical purchasing power of the Defense Working Capital Fund. This partnership ensures financial visibility and inventory accountability to the DLA resource managers while ensuring our medical logisticians have continuous supply chain management and timely, efficient medical assembly of field hospitals and medical sets and kits. This has occurred in part through a successful fielding of the Theatre Enterprise Wide Logistics System, or TEWLS, a unique commercial product that will bring that same “information dominance” and knowledge network technology to the logistics community that I described for the health care delivery community.
 
As a life cycle management command, we are attentive to and successful in intermediate supply chain management of medical supplies, equipment, and devices from factory to foxhole, foc’sle, flight line and mud. We are as successful in this arena as we are in concept development, science and technology, and advanced development of new products in the MRMC.
 
It is with great pride and a deep sense of humility that I lead and serve this talented MRMC team. ♦

INDUSTRY INTERVIEW: Z-Medica Corporation

Raymond J. Huey
CEO
Z-Medica Corporation

Raymond J. Huey joined Z-Medica in 2004 as CEO to proactively address a spike in demand for the company’s breakthrough lifesaving product, QuikClot hemostatic agent. He is also leading the company’s efforts for planned growth in existing and future markets. Huey sets the company’s strategic direction, building on the military’s successful adoption of QuikClot for use in Afghanistan and Iraq. Huey brought to Z-Medica broad experience in innovative product development, operations management, executive leadership and quality systems. An engineer by training and a veteran of the medical device industry, Huey led a $150 million division of General Electric Medical Systems, and maintained one of the global giant’s most efficient manufacturing facilities. He is a Master Black Belt in GE’s Six Sigma program.

Q: How would you describe Z-Medica’s position in the marketplace?

A: Z-Medica is the leader in the development and production of advanced hemostatic nano-technologies. Particularly in the military market, we have the most products in the field. We have delivered more than one million units of QuikClot to all branches of the U.S. military since 2002, including a recent shipment of 140,000 units of QuikClot Advanced Clotting Sponge [ACS] to the Army. We are committed to adopting world-class processes and creating the infrastructure necessary to accommodate not only growing military demand, but also continuing growth in the first responder and other markets. We want our products available to all who need them, and we want to keep them affordable for everyone. Our company is serious about our motto that, “The greatest privilege is to make a difference.”

Q: What makes QuikClot unique, and how does it work?

A: Until QuikClot, there has never been a product proven to stop massive arterial or venous bleeding outside of the operating room setting. Without QuikClot, the survival chances of a soldier wounded on the battlefield today are the same as they would have been for a soldier in the Civil War. When poured or packed directly into an open wound, the product acts like a molecular sieve, sifting molecules by size. QuikClot instantly takes in the smaller water molecules from the blood in and around the wound. The larger platelet and clotting factor molecules remain in the wound in a highly concentrated form. This promotes extremely rapid natural clotting and prevents severe blood loss. The process represents a new approach to hemostasis, which typically involves adding clotting factors rather than extracting elements to halt bleeding. QuikClot helps create a stable, powerful clot that stays firmly in place until it is removed in the field hospital or operating room.

Q: Can you explain in detail the role the military has played in your company’s growth?

A: Not only was the military our first customer for QuikClot, but the Office of Naval Research, the U.S. Marine Corps Systems Command and the Naval Medical Research Center have been partners in the original comparative testing of QuikClot and newer products including QuikClot ACS. QuikClot ACS is a new formulation and delivery system for the flagship product QuikClot. The new version offers military and first responder users an alternative delivery system and numerous features that improve its ease of use. The evolution of the product is based on field observations and feedback, and Z-Medica’s commitment to continuous research and product improvement.

Q: What is your company’s main objective for the coming year?

A: We are very focused on removing the one usage concern about QuikClot—that it can create a heat-producing mechanical action. Working with military and civilian research, development and testing partners, we are very close to accomplishing this major objective. Once this issue is resolved, we will be able to create products for use in surgical procedures where severe bleeding is an issue and in many other applications in industrial and consumer markets. This achievement will also hasten deployment among first responder units, promising to save many thousands more lives each year. ♦

Ultra-Sound, Ultra-Quick Decisions

  • Written by PATRICK CHISHOLM

ULTRASOUND EQUIPMENT HAS BECOME MISSION-ESSENTIAL WHETHER STATESIDE OR DEPLOYED FOR HEALTH CARE PROVIDERS.
 

From the Mayo Clinic to the mountains of Afghanistan, rapid advances in ultrasound technology are enabling physicians to make better-informed and faster decisions. Not only have image quality and data capabilities improved, but the package is becoming much smaller, enabling ultrasound to be much more practical and portable than in the past.

That is abundantly evident among forward surgical teams, combat-support hospitals, shock trauma platoons and expeditionary medical facilities in Iraq and Afghanistan. Physicians are using portable sonography to diagnose patients, reducing the need for invasive diagnosis procedures, as well as reducing the need to send the patient to a higher-level facility for radiologic imaging. And a common use for the product is obtaining quick information in order to answer go, no-go questions pertaining to triage.

Prior to having ultrasound in the field, in order to determine whether there was internal bleeding in the abdomen, doctors often had to make an incision there (a peritoneal lavage). Ultrasound has replaced that type of procedure, going from invasive to non-invasive. Once it is determined what is going on internally, a quick decision can be made how to triage the patient.

During the Gulf War, the ability to place medical assets very close to the front lines was limited because of the large footprints associated with the equipment. In response, DoD launched an initiative to substantially reduce that footprint, resulting in a much greater ability to move medical resources closer to the battle. The military set out to change the way it provides medical triage to troops, and solicited new equipment from industry.

The Defense Advance Research Project Agency provided funding to Bothell, Wash.-based SonoSite, at the time a division of ATL, Ultrasound to develop a very small ultrasound system. In 1999 SonoSite released that product, a 5.4-pound, handcarryable unit called the SonoSite 180 system. Used by medical teams throughout Iraq and Afghanistan (as well as in both military and civilian stateside facilities), it helps identify abdominal or chest bleeding, vascular damage, the presence of foreign bodies and many other conditions.

Trauma and vascular indications are the most common reason for use of ultrasound at the busier trauma facilities in Iraq, said Colonel Donald Jenkins, trauma medical director for U.S. Central Command, Joint Theater Trauma System. It is used to identify internal bleeding after major trauma, to identify the best site for a large central IV catheter and to determine injury to major blood vessels. “Very few radiologists or ultrasound technicians are in theater, but the ultrasound technology is everywhere, every little outpost with a physician that I have visited is using ultrasound,” recounted Jenkins. “Clinicians are being trained to use ultrasound in the CONUS [continental United States] medical treatment facilities and then applying that knowledge here in theater.”

He said that many disease, non-battle injury conditions are also amenable to ultrasound diagnosis, such as deep venous thrombosis, often seen after an injury or prolonged immobility, like a long airplane ride from the United States to the theater. Similarly, gallbladder disease diagnoses, certain cardiac tests, gynecologic examinations and other diagnoses are made possible with ultrasound.

Colonel Thomas A. Rozanski, Colonel Jeffery M. Edmonson and Colonel Sheila B. Jones, who were connected with the 21st Combat Support Hospital North, Forward Operating Base Diamondback, Mosul, Iraq, wrote in a paper that “…found ultrasonography to be most valuable in trauma (FAST) examinations, and abdominal imaging. However, we used the device for multiple other examinations, including some unusual indications such as imaging of the ocular globe, fluid collections in the popliteal fossa, shoulder varicosities, and complex subcutaneous masses.”

Ron Dickson, vice president for government and military sales at SonoSite, added that examining the eye for retinal damage another common use, is determining whether heart is beating, or whether the cardiac sac is punctured. And doctors in the field it for everyday things well, such as sick call.

Jenkins pointed out, “The fact that the technology has been made easy to use, foolproof—or as I often say as a trauma surgeon, surgeonproof— and will re-set to baseline by simply re-booting makes this very usable. All the services use the same type of device, so parts are interchangeable and the spectrum of probes for various organ system evaluations from a single machine really makes this tool valuable.”

Jenkins continued, “It’s rugged. In fact, the machine that was brought to Balad [Iraq] by my Army colleagues early in 2004 is still there in everyday use in the ER. Meanwhile, every X-ray machine has been replaced at least once, the CT scanner is on version number four, even the tents are the third ones used at this site. But our portable ultrasound device keeps on chugging along.”

The 180 system is designed with the capabilities of a mid-range product. “When you have a hand-carried system, your use model is much different than you would find with a perinatologist at Cedar Sinai Medical Center who’s doing 4-D,” said Dickson. “The 180 system is designed for rapid use to give you quick answers.” SonoSite has other product platforms that are more geared toward broader hospital or clinic usage, including the new high performance MicroMaxx system.

TO THE POINT OF CARE

Improvements in ultrasound technology are improving workflow and productivity, explained Dickson. “With the traditional technology, if a physician needs to perform an ultrasound exam, the technologist must unplug the ultrasound system, unhook it from the hospital IT network, and make sure they’ve got all their probes and their gel. And then they set off pushing a 300 to 400 pound piece of equipment down the hallway, hoping for an elevator to open with nobody in it. Once they get to where they’re going they must maneuver between beds and try to find an electrical outlet, not rolling over any cables in the process. Once the exam is complete, they must make the same trek back to the imaging department. Not only is this a hassle, but it takes a huge amount of time affecting patient throughput.”

The smaller systems can readily go to the point of care—as portable as a cell phone. Dickson added that instead of keeping the systems in the traditional imaging departments, hospitals are buying hand-carried systems to place in individual departments. “The doctor doesn’t even have to call down any more to wait for the imaging department to come up and do the exam. So it really has improved the efficiency of health care.”

Jim R. Brown, senior director of clinical and technical marketing at Phillips Medical Systems, Ultrasound Division, pointed out that surgeons are now regularly using ultrasound, and it is becoming more common in emergency rooms as well. “You’re starting to see ultrasound now migrate down to the point of care.”

Modern ultrasound machines have better ergonomic designs as well. The Society of Diagnostic Medical Sonography reported that ultrasound operators are at risk for musculoskeletal disorders such as repetitive stress injuries; an estimated 83 percent of sonographers will suffer some degree of work-related injury during their careers—at least if they’re using the older, less user-friendly technology.

“Today’s machines most often have programmable key functions, customizable panel designs, sophisticated imaging software as well as ergonomic improvements that not only enhance the imaging capabilities of the ultrasound system but also make the systems easier to use,” said Louise Kruz, cardiology marketing manager for Siemens. “Aspects like this makes it physically easier on the operator as well as improves diagnostic imaging outcome and workflow, and are core design factors in the Siemens line of ultrasound products.”

“In the old days, the machines weren’t designed very well for rapid deployment,” added Dickson. “Ergonomics and an intuitive user interface has really become a focal point in developing new equipment.”

THE FOURTH DIMENSION

Obstetrics is probably the most commonly known use of ultrasound, but that’s just one of the many applications. “Gall bladders, kidneys, liver, spleen, vascular…a busy cardiology practice could do maybe 3,000-5,000 echocardiograms in a year,” said Kruz. “Most of the biopsies that are done for prostate cancer are all ultrasoundguided.” Ultrasound plays a major role following mammography in the work-up for breast lesions.

She pointed out, “For ultrasound the rule of thumb is, it can be used on anything that’s not bone and that’s not filled with air.” X-rays, of course, are used to examine bone. And CAT scans are useful for looking at gas-filled structures such as bowels or lungs.

Siemens carries ultrasound products in all price points and configurations. And it places particular emphasis on developing systems for diagnosing difficult-to-image patients, such as patients who are obese, have breathing issues, are active or unable to remain still (pediatrics), or who have Renal disease, which is associated with a lack of water in the body.

Brown said that “We can even use ultrasound to look in babies’ brains to look for any abnormalities, especially premature infants. We’re also using ultrasound to look at musculo-skeletal type of abnormalities or sports injuries.” He affirmed that in addition to diagnoses, ultrasound can be used as a good guidance technique, such as for biopsies.

The Mike O’Callaghan Federal Hospital at Nellis AFB has requested the purchase of a Phillips iU22 ultrasound system. They need state-of-the-art ultrasound imaging for early detection and treatment of conditions including cancer, vascular disease, kidney disease, obstetric and gynecologic problems, and diseases of the breasts.

“The iU22 boasts an XStream Architecture system. That system allows multiple data streams to process simultaneously, resulting in optimal clinical performance in all modes and with all transducers,” said Master Sergeant Erica L. Perez, diagnostic ultrasound phase II course supervisor at Nellis. “The outcome is improved tissue differentiation and Doppler sensitivity. The iU22 also has automatic optimization for color Doppler resulting in maximum performance.”

Four-dimensional (i.e., 3-D plus realtime imaging) ultrasound technology is becoming more common and provides potential opportunity to obtain additional diagnostic information from ultrasound. In trasthoracic cardiology, for most patients, the frame rate and the image resolution is not yet meeting the desired clinical applications, according to Kruz. But she expects at some point in the future that technological advancements will make that possible.

Nevertheless, Kruz said that 3-D is especially effective at looking at the heart, via a transesophageal probe. “When you add on the capability of 3-D, you’re talking about beautiful image quality. So in the operative patient, you may provide a clinical benefit that they can’t get with 2-D imaging.”

And 4-D is making inroads. “We’re seeing pretty dramatic uptick in sales in 4-D capability for cardiology—about 60 to 70 percent of the premium systems are going with those advanced capabilities,” said Brown. “In radiology, adoption of 4-D is a little slower because the applications and the capability haven’t been there. But there’s an uptick in those areas as well.”

Another ultrasound technology, akin to 4-D, is holographic ultrasound. Traditional ultrasound uses the reflective properties of sound, which accounts for only about 3 percent of the sound that actually goes into the body. “Instead of looking at what’s reflected back, our technology looks at the other 97 percent of the sound that actually goes through the soft tissue in the body, and we make holograms out of that,” said Lura Powell, president and CEO of Advanced Imaging Technologies, Richland, Wash. “We generate very clear, highly detailed images of the soft tissue structures in the body. It’s very different from the type of images that you will traditionally see with ultrasound.”

With AIT’s technology, an ultrasound source sends a wave of sound through the body or the body part. And there is a second ultrasound reference source which matches the first, enabling the creation of a hologram in real time. “We get an image of the full field (or the entire cross section), different planes within the object. This provides data over the entire volume of the object,” explained Todd Garlick, principal engineer at AIT.

The technology is especially useful with breast imaging and image-guided biopsy, but is also cleared by the FDA for real-time orthopedic, pediatric and vascular imaging. “We get to see the entire anatomy rather than the very small wedge typical of conventional ultrasound. With that 3-D data set, you can determine the exact location of the object, whereas in a mammogram it’s an image where you don’t have any depth,” added Garlick. “The technology is well suited for dense tissue. It allows us to effectively image dense breast tissue, overcoming a significant limitation of mammography.”

THE FIGHTING STRENGTH

Whether it is in a small-town clinic, a busy hospital, or in a surgical tent in Iraq, the benefits of new ultrasound technologies are proving remarkable. As Rozanski, Edmonson and Jones recommend, such technology should be considered for all combat support hospitals, forward surgical teams and brigade-level medical companies. It is one additional contribution to “preserving the fighting strength” of the U.S. military. ♦

Converting from Military to Civilian

THE MILITARY HEALTH SYSTEM IS IN THE MIDDLE OF A TRANSFORMATIONAL PROCESS OF CONVERTING A NUMBER OF MILITARY HEALTH CARE POSITIONS TO CIVILIAN.

The Military Health System (MHS) provides health support for the full range of military operations and for military servicemembers and their families, military retirees, retiree family members and survivors. The Defense Health Program (DHP) appropriation supports worldwide medical and dental services to eligible beneficiaries, veterinary services, medical command headquarters, graduate medical education and other training of medical personnel, and occupational and industrial health care. The DHP appropriation supports operations of 70 inpatient facilities, 409 medical clinics, 417 dental clinics and 259 veterinary clinics, and funds multiple TRICARE contracts that augment health care delivery.

In fiscal year 2005, MHS employed approximately 42,400 federal civilian employee full-time equivalents whose costs were funded by the DHP. MHS also employed about 90,000 military medical, dental and support personnel. The cost of these military personnel who support DHP-funded activities is funded by each military department’s military personnel appropriation.

In December 2003, DoD directed the military departments to convert certain targeted numbers of military positions, including some health care positions, to federal civilian or contract positions based on evaluations that showed many military personnel were being used to accomplish work tasks that were not military-essential and could be performed more cost efficiently by civilians. According to DoD officials, the conversion process began in late 2003/early 2004 with the creation of a task force, chaired by the Director of Office of Program Analysis and Evaluation (PA&E), including members from offices of the Assistant Secretary of Defense for Health Affairs and the surgeons general for the Air Force, Army and Navy, to identify military medical and dental positions that could be converted to federal civilian or contract positions.

The task force examined 121 occupational medical and dental specialties for potential conversion. It applied a DoD medical readiness personnel sizing model to identify the baseline medical readiness personnel requirements for each military department, taking into consideration only those positions that members believed would not be required for medical readiness, would not degrade clinical capabilities, would not reduce access to medical or dental care to beneficiaries, or would not increase costs to DoD.

As the military departments began to implement the conversions, each military department reassessed the availability and affordability of civilian replacement personnel in the geographical areas where conversions were planned. Adjustments were then made to the military departments’ plans to reflect local medical commanders’ assessments.

According to officials with the offices of the surgeons general for the Air Force and Army, conversions of military health care positions in their military departments are planned to be replaced on a one-for-one basis with civilian or contract personnel. However, according to a Navy official, the Navy decided to link a reassessment of appropriate medical and dental staffing levels in its medical centers to the conversion process. This reassessment, among other things, reviewed the number and type of staffing required to meet clinical productivity goals and quality standards. The Navy concluded that there was no need to hire civilian personnel replacements for 345 of the 1,772 positions converted for fiscal year 2005 after reviewing the staff reassessment results.

THE NUMBERS

During fiscal years 2005 through 2007, the departments have converted or plan to convert a total of 5,507 military health care positions to civilian positions, representing 6.1 percent of the total DHP military personnel. Specifically, the departments converted 1,772 positions (32 percent of the total planned conversions) in fiscal year 2005, 1,645 positions (30 percent) in fiscal year 2006, and plan to convert 2,090 positions (38 percent) in fiscal year 2007.

The Navy is the most significantly affected of the three military departments by the military to civilian conversions. The Navy has converted or plans to convert 2,676 military health care positions, representing 49 percent of the total positions converted or planned for conversion in DoD. In addition, the Navy was the only department that converted positions in fiscal year 2005, converting a total of 1,772 positions—32 percent of the total number of planned/converted positions. By contrast, the Air Force has converted or plans to convert 1,214 positions, or 22 percent of the total conversions, and the Army has converted or plans to convert 1,617, or 29 percent of the total conversions.

ENOUGH PEOPLE TO HIRE?

Each of the military departments has made varying degrees of progress in hiring civilian personnel to fill military health care positions. According to military department officials, the Air Force ceased hiring actions to fill its fiscal year 2006 converted positions in January 2006 and the Army in February 2006 after enactment of the National Defense Authorization Act for fiscal year 2006. However, their experiences to date suggest they have not encountered significant difficulties hiring civilian personnel to fill converted positions.

Of the three departments, the Navy has the most experience hiring civilian replacements, filling two-thirds of the positions it converted in fiscal year 2005. According to a Navy official, the Navy converted a total of 1,772 military health care positions to civilian positions for the year.

For the 1,772 conversions that it hired in fiscal year 2005, the Navy did not begin recruiting civilians to fill the converted positions until July 2005 to allow for (1) Navy military treatment facilities to assess their staffing needs, (2) military personnel to vacate the converted positions, and (3) consultations with human resource offices to develop federal civilian job announcements. Also, the Navy decided not to fill all of the military health care positions it converted. After reassessments of medical and dental staffing levels at its facilities, the Navy decided to fill only 1,361, or 77 percent, of the 1,772 converted military positions. Over a seven-month period for these 1,361 positions, the Navy had successfully recruited 907, or 67 percent, of the civilians needed, as of January 31, 2006.

A Navy official told the GAO that there had been no significant difficulties in filling such a large number of federal civilian positions within a short period of time. However, public and private employers report a limited supply of certain types of medical and dental personnel both on a national level and in certain geographical areas. In 2005, the Bureau of Labor Statistics reported that nurses were considered difficult to hire and retain by nonmilitary employers and forecast that employers will continue to compete for nursing services.

In addition, in December 2005 the Health Resources and Services Administration, an agency of the Department of Health and Human Services, reported that about 20 percent of the U.S. population lives in a primary medical care health professional shortage area. According to a Navy official, based on this information, the Navy is recruiting on a national level to hire four types of personnel—physicians, dentists, pharmacists and laboratory officers—at its various facilities. For its other types of medical and dental positions, the Navy is seeking to hire civilian personnel by targeting local markets. Also, the Navy is using various special pay provisions to allow it to compete with other employers, such as Department of Veterans Affairs’ medical centers in selected geographical areas.

Because the Air Force and Army only began converting military health care positions to civilian positions in fiscal year 2006, their experiences hiring civilians to fill converted positions are more limited than the Navy’s experience. However, as of January 2006, the Air Force had successfully recruited 149, or 37 percent, of the 401 positions converted within four months. The Army recruited 305, or 30 percent, of the 1,029 military health care positions converted within four months. Air Force and Army officials told us that they have not experienced significant difficulties in hiring civilian replacement personnel.

IS THERE A COST—AND IS IT WORTH IT?

The GAO concluded that it is unknown whether the conversion of military health care positions to civilian positions will ultimately increase or decrease costs for DoD because:

• It is uncertain what actual compensation levels will be required to successfully hire most civilian replacement personnel.

• The programming rates the departments are considering using in their certifications to Congress about the cost of the conversions to DoD do not include the full compensation costs for military personnel.

While officials in the offices of the surgeons general for the Air Force, Army and Navy believe that the military-to-civilian conversions will not increase costs, we believe it is uncertain how much it will cost to hire civilian replacement personnel for recent and planned conversions of military health care positions and whether this cost will exceed the cost for the military positions. While the military departments have made progress in hiring civilian personnel within a short time, many civilian personnel remain to be hired. As of January 31, 2006, the Navy had recruited 67 percent of the personnel it plans to hire for the conversions made in fiscal year 2005, and the Air Force and Army had recruited 37 percent and 30 percent, respectively, of the positions they converted in fiscal year 2006. However, according to DoD officials, as of March 6, 2006, the Air Force, Army and Navy had not compared the actual costs to hire these federal civilian employees with what it had cost them to employ military personnel in these positions.

While the Air Force, Army and Navy are already well under way in converting about 5,500 military health care positions to civilian positions, they are not currently in the position to know how the conversions will affect the cost to DoD. Because none of the military departments has plans to use cost data prepared by PA&E, they risk using methodologies to certify program costs that omit several significant factors, such as training, recruitment, and educational assistance.

Without ensuring that they are accounting for the full costs—both direct and indirect—of converting the military health care positions to civilian positions, the military departments will be unable to provide Congress with accurate comparative costs for their conversions. Further, Congress will be unable to judge the extent to which the military departments’ certifications are based on anticipated compensation costs for completed and future civilian hires unless the military departments include such delineations in their congressional certifications.

To ensure that the military departments account for the full costs of military health care positions converted or planned for conversion when they report to Congress, the GAO has recommended that the Secretary of Defense direct the Secretaries of the Air Force, Army and Navy to coordinate the development of their congressional certifications for military health care conversions with the PA&E in order to consider the full cost for military personnel and for federal civilian or contract replacement personnel in assessing whether anticipated costs to hire civilian replacement personnel will increase costs. It further recommended that DoD address in their congressional certifications for military health care conversions the extent to which total projected costs for hiring federal civilian or contract personnel include actual compensation costs for completed hires and anticipated compensation costs for future hires.

Although not disagreeing with the recommendation to coordinate their cost estimates with the PA&E, DoD has commented that the PA&E final report is not expected to be available before it (DoD) is to make the reports final, thus making coordination difficult.

As to the congressional certifications for the conversions, DoD believes that the recommendation is unnecessary as requirements are already in place requiring similar actions be taken. ♦

Letting Sensors Do the Work

UNATTENDED CBR SENSORS AND DETECTION SYSTEMS FIND FAVOR IN GLOBAL MILITARIES.


Unattended sensors and detection systems provide warfighters with an early detection capability for chemical, biological and radiation (CBR) threats. Advancements in detection, analysis, identification and warning technologies have encouraged the U.S. Department of Defense and overseas military services to increase their investment in these programs that provide near-real-time protection for service men and women.

As these technologies mature, the guiding hand of the U.S. Congress encourages DoD to look beyond a single-service application and towards developing and deploying joint (multiservice) CBR programs.

Unattended CBR sensors and detection systems will also be fielded in next generation weapons platforms, in particular, the U.S. Army’s Future Combat System (FCS).

UNATTENDED SYSTEM PRIMER

Lockheed Martin CBRNE Defense Systems has two systems of interest, the Biological Aerosol Warning System (BAWS) and the Chemical, Biological and Radiological Early Warning System (CBREWS). The CBRNE team provided an in-depth overview about these programs.

The company’s BAWS operates as a networked array of point sensors. “By network, I mean a network in which the data is fused, and the information from one sensor is compared with and shared with the information from another sensor,” said Richard Read, senior manager, business development.

A notional system consists of one base station and 10 remote sensors. While the network capacity is 50 sensors, “At the practical limit, we recommend no more than 20 on a network, but we have the capability to network together networks—to build it as large as it needs to be built,” elaborated Read.

Each remote sensor contains a global positioning system receiver, a solid-state air mass sensor to measure wind speed and direction, a humidity indicator, and other hardware components and software.

Network communications are based on a radio link that can operate over multiple frequencies. Only one frequency is active at any one time.

This system “does not require a full-time operator to monitor the network at the base station,” said Tom Notaro, CBRNE business area manager. “The system is designed to notify the operator of any alert or alarm conditions as they occur so he or she is free to perform other tasks,” he added. “If conditions are not sufficient for an alarm, the operator will see a yellow icon on his monitor which says, ‘Sensor number X is in alert’, and lets you know something is happening. Our algorithm requires more than one sensor to go off—and by using the power of networking, we are able to keep the false alarm rate very, very low.”

The operator at the base station can remotely direct the sensor in alarm mode to collect a dry air sample. The sample can be retrieved and run through a number of analysis techniques for identification.

The supporting particle count technology is the heart of BAWS. Each of the remote sensors continuously monitors the air and computes an existing background level of particles in a size range of interest— between 2 and 10 microns.

If there is a sudden increase in particles in the prescribed size range, the sensor will send a signal back to the base station where the data are fed into a software algorithm. Analyses include which sensor is reporting, whether other sensors are showing similar effects, the current wind speed and direction and humidity, and other variables that determine whether conditions warrant an alarm.

The BAWS’s early warning function “provides the commander with enough information on whether to go into a protective posture, and subsequently collect the sample, send it back for analysis. If it turns out it was a positive attack, he or she can take follow-on medical and other actions,” emphasized Read.

Chemical, radiation, motion and other sensors may be added to the unit and monitored through the network.

During fall 2001, the initial BAWS unit was bought by the Czech military, which currently has “four (plus) operating systems and pending orders for another two units and its variants,” revealed Read. Other BAWS units have been sold to Germany and Canada for test and evaluation. The Japan Defense Agency selected the system for their Ground Self Defense Force (GSDF). In January 2006, the GSDF received an initial four units as part of an unspecified larger order.

A second Lockheed Martin product, CBREWS, is an integrated system that takes the BAWS and adds chemical and radiological sensors.

The chemical sensor is the Chem- Pro 100 supplied by Environics of Finland. The radiation sensor is the UDR-13 pocket radiac furnished by Canberra, of the United States.

A major BAWS and CBREWS upgrade was unveiled in June 2006. The improvement involves the addition of an ultra-violet, light-induced, fluorescence capability so that “not only will we detect the increased particle count, but once we have confirmed that, we will subject the air stream to a fluorescence, using a light-emitting diode rather than a laser,” divulged Read. “If the particle stream fluoresces, that gives an indication that we have biological material present.”

Mesosystems is Lockheed Martin’s partner for this upgrade.

Other CBR sensors and systems are meeting U.S. joint warfighter requirements as directed by Congress.

CAPITOL HILL EYES JOINTNESS

Contemporary congressional concern about the proliferation of chemical and biological weapons and the readiness of U.S. forces to operate in a contaminated environment has been most evident since the Gulf War.

One post-Gulf War document, the National Defense Authorization Act for fiscal year 1994, directed the Secretary of Defense to take specific actions designed to improve chemical and biological defense—including the fielding of joint systems and equipment for this mission.

Three representative joint systems, which were generated as a result of the document, are highlighted below.

JOINT BIOLOGICAL PROGRAMS

Joint biological sensor and detection systems are designed for mobile- and fixed-site applications.

The Joint Biological Point Detection System (JBPDS) is a modular suite of equipment that provides the warfighter with detection and presumptive identification of biological warfare agents in near real time. The system fully automates the biological detection and warning, sample collection, and identification of airborne agents.

The JBPDS is fielded in four variants: man-portable, shelterbased, ship-based and trailer-mounted.

General Dynamics Armament and Technical Products (ATP) is the prime contractor.

In April 2006, the U.S. Army Research, Development and Engineering Command Acquisition Center awarded the company a $45 million contract for production, testing and field support packages for JBPDS.

A second program, the Joint Portal Shield (JPS) Biological Detection System, is an automated biological detection and identification system specifically designed for fixed sites. JPS units are in service with component commands in U.S. Central Command and U.S. Pacific Command areas of responsibility.

The JPS sensor suite automates the detection, collection and identification of biological warfare agents, and reports this information to a centralized command post that monitors and operates the sensors via a radio modem or Ethernet.

Sentel provides full life cycle software development support for JPS. The company’s efforts provide a capability to detect and identify eight biological warfare agents simultaneously, all within 15 minutes.

According to the joint program manager, Joint Vaccine Acquisition Program, the MARK IV is the current system configuration. Improvements over the previous system include an enhanced detection capability through the addition of the Biological Agent Warning Sensor (also referred to as BAWS) and a more effective identification capability through addition of the progressive assay reader (PAR)—a camera technology to read the assay strips used to test for the presence of biological agents.

General Dynamics ATP produces the BAWS. Sentel develops the software for PARS and assembled the devices for the Joint Executive Program Office for Chemical and Biological Defense. Future Improvements envisioned for JPS include incorporating the VDR-2 radiation sensor to provide complete NBC detection in one integrated sensor.

ONE JOINT CHEMICAL SOLUTION

The Joint Service Lightweight Standoff Chemical Agent Detector (JSLSCAD) is comprised of detector, scanner and electronics modules. It is a small, lightweight (less than 50 pounds), fully automatic, standoff chemical agent detector, capable of on-themove, real-time detection from either aerial or surface platforms and fixed sites. The unit will detect and alarm to a chemical agent cloud up to five kilometers (3.1 miles) away. Six nerve, three blister and two blood agents are capable of being detected by the device.

The company further states that JSLSCAD provides a 360- degree coverage for ground- and sea-based platforms, and an aerial craft detection range of 60 degrees, at up to 5 km.

The detector provides chemical identification information and data for activation of countermeasures to avoid contamination. JSLSCAD is equipped for visual and audible alarms and displays the agent class and relative position, both locally and for transmission to the Joint Warning and Reporting Network. JSLSCAD also has the capability to indicate an all-clear condition.

Unattended CBR sensors and detection systems will also be deployed in next-generation weapons platforms, in particular, the FCS.

UNATTENDED SENSORS FOR FCS

The core of the U.S. Army’s embryonic FCS is a highly integrated structure of 18 manned and unmanned (MUM), air and ground maneuver, maneuver support and sustainment systems, bound together by a joint, distributed network. The MUM systems include unattended ground sensors (UGS).

An FCS program white paper (dated April 11, 2006) states that the UGS consists of two subgroups of sensing systems, one of which is the chemical, biological, radiological and nuclear.

The FCS UGS package is envisioned to perform mission tasks such as perimeter defense, surveillance, target acquisition and situational awareness, including CBRN early warning.

The FCS lead system integrator team (Boeing and Science Application International Corporation (SAIC)) selected Textron Systems to furnish 15 tactical and unattended ground sensors, including the CBRN-UGS.

U.S. Army and industry offices declined to answer a number of questions about the CBRN-UGS’s envisioned operational capabilities including: is the UGS being designed to be left behind or retrievable? Will it be deployed indoors and/or outdoors?

FCS systems testing will be conducted by the Evaluation Brigade Combat Team. This organization will be established at Fort Bliss, Texas, in June 2007. ♦
