Factors influencing humanitarian care and the treatment of local patients within the deployed military medical system: casualty referral limitations.

BACKGROUND: Humanitarian medical care is an essential task of the deployed military health care system. The purpose of this study was to analyze referral acceptance in treating injured local national patients during Operation Enduring Freedom. METHODS: A prospective observation study of local nationals who were referred for humanitarian trauma care in Afghanistan from March through August 2009. RESULTS: Sixty-six patients were referred for evacuation for suspected non-coalition-caused injuries. The bed status at the receiving hospital was defined as green (able to accept patients), amber (nearing capacity), and red (at capacity). The only factor associated with acceptance was the accepting hospital bed status (odds ratio = 1.57%, 95% confidence interval, 1.11-2.22; P = .009). Factors not significant were age, the province of origin, the type of referring facility, a prior operation before the request, patient status/affiliation, or the mechanism of injury. CONCLUSIONS: Humanitarian medical care is directly related to the capacity for high-acuity care because bed availability is the predominate reason for acceptance or rejection.

Early results after introduction of biliopancreatic diversion/duodenal switch at a military bariatric center.

BACKGROUND: Biliopancreatic diversion with duodenal switch (BPD/DS) is one of the most effective procedures in terms of weight loss and durability. It is also one of the most complex and highest risk bariatric procedures. The authors report their initial experience with BPD/DS. METHODS: A retrospective review of all patients undergoing BPD/DS was performed, including a descriptive analysis of demographics, operative data, complications, and outcomes. Results were also compared with those among a group of 100 patients undergoing laparoscopic gastric bypass (LGB). RESULTS: Forty-three patients were identified. Mean preoperative body mass index was 52 kg/m(2), and 56% of patients had body mass indexes > 50 kg/m(2). Twenty (47%) were attempted laparoscopically, with 5 (25%) requiring conversion to open approach. Overall mean operative time was 269 minutes, with no significant difference between laparoscopic (256 minutes) and open (280 minutes). No major intraoperative complications occurred. Major postoperative complications included 4 gastric sleeve leaks, 2 small bowel obstructions, 1 intra-abdominal hemorrhage, and 1 duodenal stump leak. There was 1 death. Mean percentage excess body weight loss was 85% at 1 year. No patients developed severe malabsorptive symptoms or evidence of protein malnutrition. BPD/DS was associated with longer operative times and higher complication rates (P < .05 for both) compared with LGB but had significantly greater weight loss at 1 year (P < .05). CONCLUSION: BPD/DS is a complex procedure associated with increased operative times, increased risk for conversion from laparoscopic to open approach, and higher postoperative complication rates. However, it results in significantly greater weight loss than LGB without major adverse nutritional impact.

Socioeconomic disparities in eligibility and access to bariatric surgery: a national population-based analysis.

BACKGROUND: To analyze the socioeconomics of the morbidly obese patient population and the impact on access to bariatric surgery using 2 nationally representative databases. Bariatric surgery is a life-changing and potentially life-saving intervention for morbid obesity. Access to bariatric surgical care among eligible patients might be adversely affected by a variety of socioeconomic factors. METHODS: The national bariatric eligible population was identified from the 2005-2006 National Health and Nutrition Examination Survey and compared with the adult noneligible population. The eligible cohort was then compared with patients who had undergone bariatric surgery in the 2006 Nationwide Inpatient Sample, and key socioeconomic disparities were identified and analyzed. RESULTS: A total of 22,151,116 people were identified as eligible for bariatric surgery using the National Institutes of Health criteria. Compared with the noneligible group, the bariatric eligible group had significantly lower family incomes, lower education levels, less access to healthcare, and a greater proportion of nonwhite race (all P <.001). Bariatric eligibility was associated with significant adverse economic and health-related markers, including days of work lost (5 versus 8 days, P <.001). More than one third (35%) of bariatric eligible patients were either uninsured or underinsured, and 15% had incomes less than the poverty level. A total of 87,749 in-patient bariatric surgical procedures were performed in 2006. Most were performed in white patients (75%) with greater median incomes (80%) and private insurance (82%). Significant disparities associated with a decreased likelihood of undergoing bariatric surgery were noted by race, income, insurance type, and gender. CONCLUSION: Socioeconomic factors play a major role in determining who does and does not undergo bariatric surgery, despite medical eligibility. Significant disparities according to race, income, education level, and insurance type continue to exist and should prompt focused public health efforts aimed at equalizing and expanding access.

Application of the Mangled Extremity Severity Score in a combat setting.

OBJECTIVE: The aim of this study was to examine the Mangled Extremity Severity Score (MESS) in a combat setting. METHODS: Data on extremity injuries were collected from a forward surgical team. MESS and Revised Trauma Score values were retrospectively calculated for each patient. Student's t test was used to compare amputated and salvaged limbs. RESULTS: A total of 60 extremities was identified in 49 patients. There were 10 major vascular repairs (20%). MESS values differed significantly for the eight amputations performed (mean MESS, 7.87 +/- 1.91) and 50 salvaged extremities (mean MESS, 2.44 +/-_ 0.438; p = 0.001). CONCLUSIONS: A MESS of >7 correlated with amputation, thus validating the MESS in a combat setting. A young average patient age and high-energy injury mechanism on the battlefield leave ischemic time and shock as the most important factors in dictating whether a MESS is >7 or <7.

The use of damage-control principles for penetrating pelvic battlefield trauma.

BACKGROUND: High-velocity, penetrating pelvic injuries present one of the most difficult challenges to military trauma surgeons. The patients often present in physiologic extremis, and their injury-site patterns frequently include soft tissue, pelvic fractures, genitourinary tract, rectum, vascular structures, and intra-abdominal viscera. METHODS: A retrospective review of the 31st Combat Support Hospital damage-control laparotomy database, under an Institutional Review Board-approved protocol, revealed 28 patients with severe multisystem penetrating pelvic injuries. Up to 75 data points were queried for each patient and subjected to descriptive analysis using SPSS 11.0.4 Statistical Software Package (SPSS, Inc, Chicago, IL). RESULTS: Of 28 patients with severe penetrating pelvic injuries, 43% had extraperitoneal rectal, 43% had urologic, and 50% had major vascular injuries. On average, patients required 4 abdominal operations for treatment of all injuries. Six of 28 (21%) patients died within the first week after injury, and 36% of patients with vascular and rectal injuries died. CONCLUSIONS: Management of these injuries frequently required damage-control techniques and a staged, multidisciplinary approach to reconstruction. Combined rectal and vascular injuries were the most devastating in this type of injury complex.
