Prophylactic Antibiotic Use for Penetrating Trauma in Prolonged Casualty Care: A Review of the Literature and Current Guidelines.

ABSTRACT: Prolonged casualty care (PCC), previously known as prolonged field care, is a system to provide patient care for extended periods of time when evacuation or mission requirements surpass available capabilities. Current guidelines recommend a 7-10-day course of ertapenem or moxifloxacin, with vancomycin if methicillin-resistant Staphylococcus aureus is suspected, for all penetrating trauma in PCC. Data from civilian and military trauma have demonstrated benefit for antibiotic prophylaxis in multiple types of penetrating trauma, but the recommended regimens and durations differ from those used in PCC, with the PCC guidelines generally recommending broader coverage. We present a review of the available civilian and military literature on antibiotic prophylaxis in penetrating trauma to discuss whether a strategy of broader coverage is necessary in the PCC setting, with the goal of optimizing patient outcomes and antibiotic stewardship, while remaining cognizant of the challenges of moving medial material to and through combat zones. Empiric extended gram-negative coverage is unlikely to be necessary for thoracic, maxillofacial, extremity, and central nervous system trauma in most medical settings. However, providing the narrowest appropriate antimicrobial coverage is challenging in PCC due to limited resources, most notably delay to surgical debridement. Antibiotic prophylaxis regimen must be determined on a case-by-case basis based on individual patient factors while still considering antibiotic stewardship. Narrower regimens, which focus on matching up the site of infection to the antibiotic chosen, may be appropriate based on available resources and expertise of treating providers.When resources permit in PCC, the narrower cefazolin-based regimens (with the addition of metronidazole for esophageal or abdominal involvement, or gross contamination of CNS trauma) likely provide adequate coverage. Levofloxacin is appropriate for ocular trauma. Ideally, cefazolin and metronidazole should be carried by medics in addition to first-line antibiotics (moxifloxacin and ertapenem).

Quality Indicators for Major Depressive Disorder in Adults: A Review of Performance Measures by the American College of Physicians.

Major depressive disorder (MDD) is a severe mood disorder that affects at least 8.4% of the adult population in the United States. Characteristics of MDD include persistent sadness, diminished interest in daily activities, and a state of hopelessness. The illness may progress quickly and have devastating consequences if left untreated. Eight performance measures are available to evaluate screening, diagnosis, and successful management of MDD. However, many performance measures do not meet the criteria for validity, reliability, evidence, and meaningfulness.The American College of Physicians (ACP) embraces performance measurement as a means to externally validate the quality of care of practices, medical groups, and health plans and to drive reimbursement processes. However, a plethora of performance measures that provide low or no value to patient care have inundated physicians, practices, and systems and burdened them with collecting and reporting of data. The ACP's Performance Measurement Committee (PMC) reviews performance measures using a validated process to inform regulatory and accreditation bodies in an effort to recognize high-quality performance measures, address gaps and areas for improvement in performance measures, and help reduce reporting burden. Out of 8 performance measures, the PMC found only 1 measure (suicide risk assessment) that was valid at all levels of attribution. This paper presents a review of MDD performance measures and highlights opportunities to improve performance measures addressing MDD management.

Quality Indicators for Osteoporosis in Adults: A Review of Performance Measures by the American College of Physicians.

Primary osteoporosis is characterized by decreasing bone mass and density and reduced bone strength that leads to a higher risk for fracture, especially hip and spine fractures. The prevalence of osteoporosis in the United States is estimated at 12.6% for adults older than 50 years. Although it is most frequently diagnosed in White and Asian females, it still affects males and females of all ethnicities. Osteoporosis is considered a major health issue, which has prompted the development and use of several performance measures to assess and improve the effectiveness of screening, diagnosis, and treatment. These performance measures are often used in accountability, public reporting, and/or payment programs. However, the reliability, validity, evidence, attribution, and meaningfulness of performance measures have been questioned. The purpose of this paper is to present a review of current performance measures on osteoporosis and inform physicians, payers, and policymakers in their selection of performance measures for this condition. The Performance Measurement Committee identified 6 osteoporosis performance measures relevant to internal medicine physicians, only 1 of which was found valid at all levels of attribution. This paper also proposes a performance measure concept to address a performance gap for the initial approach to therapy for patients with a new diagnosis of osteoporosis based on the current American College of Physicians guideline.

Beyond Trauma: High-Volume Critical Care Medicine in a Military Medical Center-Based Military-Civilian Partnership.

INTRODUCTION: Critical Care Internal Medicine (CCIM) is vital to the U.S. Military as evidenced by the role CCIM played in the COVID-19 pandemic response and wartime operations. Although the proficiency needs of military surgeons have been well studied, this has not been the case for CCIM. The objective of this study was to compare the patient volume and acuity of military CCIM physicians working solely at Military Treatment Facilities (MTFs) with those at MTFs also working part-time in a military-civilian partnership (MCP) at the University Medical Center of Southern Nevada (UMC). MATERIALS AND METHODS: We analyzed FY2019 critical care coding data from the Military Health System and UMC comparing the number of critical care encounters, the number of high-acuity critical care encounters, and the Abilities/Activity component of the Knowledge, Skills, and Abilities/Clinical Activity (KSA) score. This analysis was restricted to critical care encounters defined by Current Procedural Terminology codes for critical care (99291 and 99292). A critical care encounter was considered high acuity if the patient had ICD-10 codes for shock, respiratory failure, or cardiac arrest or had at least three codes for critical care in the same episode. RESULTS: The five AF CCIM physicians in the MCP group performed 2,019 critical care encounters in 206 days, with 63.1% (1,273) being defined as high acuity. The total number of MTF critical care encounters was 16,855 across all providers and services, with 28.9% (4,864) of encounters defined as high acuity. When limited to CCIM encounters, MTFs had 6,785 critical care encounters, with 32.0% being high acuity (2,171). Thus, the five AF CCIM physicians, while working 206 days at the UMC, equated to 12.0% (2,019/16,855) of the total critical care MTF encounters, 27.2% (1,273/4,684) of the total high-acuity MTF critical care encounters, and 29.8% (2,019/6,785) of the MTF CCIM encounters, with 58.6% (1,273/2,171) of the MTF CCIM high-acuity encounters.The USAF CCIM physicians in the MCP group performed 454,395 KSAs in 206 days, with a KSA density per day of 2,206. In the MTF group, CCIM providers generated 2,344,791 total KSAs over 10,287 days, with a KSA density per day of 227.9. Thus, the five CCIM physicians at the UMC accounted for 19.38% of the MTF CCIM KSAs, with a KSA density over 10 times higher (2,206 vs. 227.9). CONCLUSIONS: The volume and acuity of critical care at MTFs may be insufficient to maintain CCIM proficiency under the current system. Military-civilian partnerships are invaluable in maintaining clinical proficiency for military CCIM physicians and can be done on a part-time basis while maintaining beneficiary care at an MTF. Future CCIM expeditionary success is contingent on CCIM physicians and team members having the required CCIM exposure to grow and maintain clinical proficiency.Limitations of this study include the absence of off-duty employment (moonlighting) data and difficulty filtering military data down to just CCIM physicians, which likely caused the MTF CCIM data to be overestimated.

Performance Measures for Physicians Providing Clinical Care Using Telemedicine: A Position Paper From the American College of Physicians.

There has been an exponential growth in the use of telemedicine services to provide clinical care, accelerated by the COVID-19 pandemic. Clinical care delivered via telemedicine has become a major and accepted method of health care delivery for many patients. There is an urgent need to understand quality of care in the telemedicine environment. This American College of Physicians position paper presents 6 recommendations to ensure the appropriate use of performance measures to evaluate quality of clinical care provided in the telemedicine environment.

Novel Use of Seraph-100™ Blood Purification Therapy in Heat Stroke.

The Seraph-100™ is a purification filter that blunts cytokine storm, providing a more favorable environment to establish immune homeostasis. We present a novel case of compassionate use of Seraph filter in a young, healthy active duty service member with heat injury-induced massive inflammatory response. The patient is a previously healthy 26-year-old male with altered mental status, tachycardia, fever to 40.3 °C, and hypotension after losing consciousness during a 4-mile run. He had a history of one heat injury in college and took no medications or supplements. Initial workup demonstrated hemoconcentration, leukocytosis, and hyperkalemia. He was intubated, received isotonic crystalloid fluid, and was admitted to the intensive care unit. The patient developed vasopressor-resistant shock and multiorgan failure with rhabdomyolysis requiring continuous renal replacement therapy. The addition of the Seraph resulted in improved hemodynamic stability, decreased inflammatory markers, and improved organ function. Approximately 1 week after the final Seraph treatment, the patient had an abrupt massive lower gastrointestinal bleed and was transitioned to comfort care by family. We present the novel use of Seraph in the setting of multiorgan failure and hyperinflammatory state due to heat injury. The patient's vasopressor refractory distributive shock was believed to be secondary to heat stroke-induced massive inflammatory response, leading to a trial of Seraph therapy. This case demonstrates that the Seraph filter has the potential to improve hemodynamic instability and reduce cytokine storm in nonsepsis patients.

Recognizing Gender Parity in Military Medicine: An Analysis of Plenary Speakers and Award Recipients at Military American College of Physicians Chapter Meetings.

INTRODUCTION: Despite the advances toward gender parity in medicine, a gap exists in the recognition of women physicians at academic and subspecialty medical conferences as plenary speakers and award winners. Conferences are cornerstones in the practice of medicine because they serve as platforms to showcase physicians' successes and disseminate work. The selection of who is honored at such events can impact an individual's career by creating networks that may lead to future opportunities. Additionally, the trend of who is honored may create expectations in the minds of trainees and early career physicians about what qualities help an individual achieve success. Our group sought to determine whether there was a gender gap in award recognition and speakership opportunities at the American College of Physicians (ACP) annual military chapter meetings. METHODS: This was a cross-sectional study with data extracted from publicly available conference programs for the Army-Air Force annual ACP meetings and the Navy annual ACP meetings. Five years of data erewere reviewed for invited plenary speakers. Ten years of data were reviewed for award recipients. For an award to be included, it had to have a preset description and criteria for recipient selection. Awards not given annually or awards given for less than 3 years were excluded. Individuals' gender was determined based on the first name and confirmed through internet searches of pronoun descriptors from professional websites. Comparisons were done using Fisher's exact test and chi-square tests when appropriate, with statistical significance set at a two-tailed P-value of <.05. RESULTS: Women comprised 26-30% of the chapter membership and there was no significant difference in gender distribution between the chapters. Fourteen of the 69 plenary speakers were women (20%), with significantly fewer women presenters in the Navy as compared to men. Thirty-six of the 134 award winners were women (27%), which was not significantly different from the overall chapter gender distributions. While women recipients of lifetime, teaching, research, and medical student awards were not significantly different from chapter gender distribution, women faculty were significantly more likely to receive an award for teaching than for research, with women receiving 13 of the 28 teaching awards (41%), and none of the 10 faculty research awards. CONCLUSIONS: The military chapter ACP meetings reviewed mirrored civilian data in many ways, although military plenary speaker and award recipient distributions were more representative of the gender distribution of the branches. Review of the nomination process, planning committee selection, and opportunities for diversity training could be optimized to ensure that future conferences have a gender-balanced representation of individuals being honored. Improving upon current practices is important for the growth and retention of women military physicians.

Ten Leadership Principles from the Military Applied to Critical Care.

Core military leadership principles associated with success during wartime have previously translated to success in the civilian business and healthcare sectors. A review of these principles may be particularly valuable during times of increased and sustained stress in the intensive care unit. In this perspective paper, we provide an overview of 10 of these principles categorized under the following three essential truths: 1) planning is crucial, but adaptability wins the day; 2) take care of your people, and your people will take care of everything else; and 3) communication is the key to success. We reflect on these three truths and the 10 key principles that fall under them. As critical care physicians who have served in the military health system across two decades of war, we believe that internalizing these key leadership principles will result in optimized performance at multiple levels when crisis condition are encountered.

A Non-Comparative Prospective Pilot Study of Ketamine for Sedation in Adult Septic Shock.

Introduction: Sedation and analgesia in the intensive care unit (ICU) for patients with sepsis can be challenging. Opioids and benzodiazepines can lower blood pressure and decrease respiratory drive. Ketamine is an N-methyl-D-aspartate (NMDA) receptor antagonist that provides both amnesia and analgesia without depressing respiratory drive or blood pressure. The purpose of this pilot study was to assess the effect of ketamine on the vasopressor requirement in adult patients with septic shock requiring mechanical ventilation. Materials and Methods: We conducted a two-phase study in a multi-disciplinary adult ICU at a tertiary medical center. The first phase was a retrospective chart review of patients admitted with septic shock between July 2010 and July 2011; 29 patients were identified for a historical control group. The second phase was a prospective, non-randomized, open-label pilot study. Patients were eligible for inclusion if they were 18-89 yr of age with a diagnosis of septic shock, who also required mechanical ventilation for at least 24 h, concomitant sedation, and vasopressor therapy. Pregnant patients, patients in the peri-operative timeframe, and patients with acute coronary syndrome were excluded. Patients enrolled in the phase two pilot study received ketamine as the primary sedative. Ketamine was administered as a 1-2 mg/kg IV bolus, then as a continuous infusion starting at 5 mcg/kg/min, titrated 2 mcg/kg/min every 30 min as needed to obtain a Richmond Agitation Sedation Scale (RASS) goal of -1 to -2. If continuous sedation was still required after 48 h, patients were transitioned off ketamine and sedative strategy reverted to usual ICU sedation protocol. The primary outcome was the dose of vasopressor required at 24, 48, 72 and 96 h after enrollment. Secondary outcomes included cumulative ketamine dose, additional sedative and analgesics used, cumulative sedative and analgesic dosing at all time periods, corticosteroid use, days of mechanical ventilation, ICU LOS, hospital LOS, and mortality. Contiguous data were analyzed with unpaired t-tests and categorical data were analyzed with two-tailed, Fisher's exact test. This study was approved by our Institutional Review Board. Results: From January 2012 to April 2015, a total of 17 patients were enrolled. Patient characteristics were similar in the control and study group. Ketamine was discontinued in one patient due to agitation at 36 h. There was a trend towards decreased norepinephrine and vasopressin use in the study group at all time periods. Regarding secondary outcomes, the study group received less additional analgesia with fentanyl at 24 and 48 h (p < 0.001), and less additional sedation with lorazepam, midazolam or dexmedetomidine at 24 h (p = 0.015). Conclusion: This pilot study demonstrated a trend towards decreased vasopressor dose, and decreased benzodiazepine and opiate use when ketamine is used as the sole sedative. The limitations to our study include a small sample size and those inherent in using a retrospective control group. Our findings should be further explored in a large, randomized prospective study.

Critical Care in the Military Health System: A Survey-Based Summary of Critical Care Services.

Introduction: Critical care is an important component of in-patient and combat casualty care, and it is a major contributor to U.S. healthcare costs. Regular exposure to critically ill and injured patients may directly contribute to wartime skills retention for military caregivers. Data describing critical care services in the Military Health System (MHS), however, is lacking. This study was undertaken to describe MHS critical care services, their resource utilization, and differences in care practices amongst military treatment facilities (MTFs). Materials and Methods: Twenty-six MTFs representing 38 adult critical care services or intensive care units (ICUs) were surveyed. The survey collected information about organizational structure, resourcing, and unit characteristics at the time of a concurrent 24-h point-prevalence survey designed to describe patient characteristics and staffing in these facilities. The survey was anonymous and protected health information was not collected. We analyzed the data according to high capacity centers (HCCs) (≥200 beds) and low capacity centers (LCCs) (<200 beds). Differences between HCCs and LCCs were compared using Fisher's exact test. Results: Seventeen MTFs (7 HCCs and 10 LCCs), representing 27 ICUs, responded to the survey. This was a 65% response rate for MTFs and a 71% response rate for services/ICUs. HCCs reported more closed vs. open ICUs; more dedicated critical care services (i.e., medical and surgical ICUs vs. mixed ICUs); fewer respiratory therapists available, but more with certification; more total nursing staff and more critical care certified nurses; the use of subjectively more effective protocols (10.5 vs. 6.7 protocols/unit or service); higher utilization of an ICU daily rounds checklist (65% vs. 0%); and less consistency of clinician type participation during multidisciplinary rounds. ICU leadership structure was similar among the institutions. The majority of respondents were unable to provide summary APACHE II scores, but HCCs were more likely to submit this information than LCCs. Most centers perform multidisciplinary rounds daily, but they are more likely to be run by a physician credentialed in critical care at HCCs (85% vs. 59%, p < 0.05). 67% of respondents reported mortality rates <5%. The two services that reported mortality rates greater than 10% were both LCCs. Conclusion: This is the first comprehensive report about MHS critical care services. Despite notable variability in data reporting, an important finding itself, this study highlights notable differences in organizational structure and resourcing between HCCs and LCCs within the MHS. The clinical implication of these differences (i.e., impact on patient outcomes) of these differences require further study. Better understanding of MHS critical care services may improve enterprise decision-making about these services which could ultimately improve care of combat casualties.

Critical Care in the Military Health System: A 24-h Point Prevalence Study.

Background: Healthcare expenditures are a significant economic cost with critical care services constituting one of its largest components. The Military Health System (MHS) is the largest, global healthcare system of its kind. In this project, we sought to describe critical care services and the patients who receive them in the MHS. Methods: We surveyed 26 military treatment facilities (MTFs) representing 38 critical care services or intensive care units (ICUs). MTFs with multiple ICUs and critical care services responded to the survey as services (e.g., surgical or medical ICU service), whereas MTFs with only one ICU responded as a unit and gave information about all types of patients (i.e., medical and surgical). Our survey was divided into an administrative portion and a 24-h point prevalence survey of patients and patient care. The administrative portion is reported separately in this journal. The 24-h point prevalence survey collected information about all patients present in, admitted to, or discharged from participating services/units during the same 24-h period in December 2014. The survey was anonymous and protected health information was not collected. Findings: Sixteen MTFs (69%) and 27 ICU services/units (71%) returned the point prevalence survey. MTFs with >200 beds (n = 3, 22%) were categorized as "high capacity centers" (HCCs) whereas those with ≤200 beds (n = 13, 78%) were characterized as low capacity centers (LCCs). Two MTFs (one HCC and one LCC) returned only administrative data. The remaining 16 MTFs reported data about 151 patients. In all, 100 (67%) of the patients were at three HCCs during this study period. One HCC accounted for 39% (59 patients) of all patient care during this study. Most patients were cared for in mixed medical/surgical ICUs (34.4%), followed by medical (21.2%), surgical (18.5%), trauma (11.9%), cardiac (7.9%), and burn (6.0%) ICUs. The most common medical indication for admission was cardiac followed by general medical. The most common surgical indications for admission were trauma, other, and cardiothoracic surgery. The average APACHE II score of all patients across both LCCs and HCCs was 11 ± 8.1 (8 ± 7.8 vs. 13 ± 7.7 p = 0.008). The lower acuity of patients in this study is reflected in a high turnover rate, low rate of arterial and central line placements (33%), and low rates of life support (all types, 30%; mechanical ventilation only, 21.2%; noninvasive mechanic ventilation only, 7.9%; and vasoactive medications, 6.6%). Thirty-five (23.2%) patients within the study were affected by a total of 57 complications. The three most common complications experienced were acute kidney injury, bleeding, and sepsis. Discussion: This is the first detailed report about MHS critical care services and the patients receiving care. It describes a low acuity ICU patient population, concentrated at larger MTFs. This study highlights the need for the establishment of a system that allows for the continuous collection of high priority information about clinical care in the MHS in order to facilitate implementation of standardized protocols and process improvements.

An End-of-Year Oral Examination for Internal Medicine Residents: An Assessment Tool for the Clinical Competency Committee.

BACKGROUND: Comprehensive evaluations of clinical competency consume a large amount of time and resources. An oral examination is a unique evaluation tool that can augment a global performance assessment by the Clinical Competency Committee (CCC). OBJECTIVE: We developed an oral examination to aid our CCC in evaluating resident performance. METHODS: We reviewed tools used in our internal medicine residency program and other training programs in our institution. A literature search failed to identify reports of a similar evaluation tool used in internal medicine programs. We developed and administered an internal medicine oral examination (IMOE) to our postgraduate year-1 and postgraduate year-2 internal medicine residents annually over a 3-year period. The results were used to enhance our CCC's discussion of overall resident performance. We estimated the costs in terms of faculty time away from patient care activities. RESULTS: Of the 54 residents, 46 (86%) passed the IMOE on their first attempt. Of the 8 (14%) residents who failed, all but 1 successfully passed after a mentored study period and retest. Less than 0.1 annual full-time equivalent per faculty member was committed by most faculty involved, and the time spent on the IMOE replaced regular resident daily conference activities. CONCLUSIONS: The results of the IMOE were added to other assessment tools and used by the CCC for a global assessment of resident performance. An oral examination is feasible in terms of cost and can be easily modified to fit the needs of various competency committees.

Analysis of an electromagnetic tube placement device versus a self-advancing nasal jejunal device for postpyloric feeding tube placement.

BACKGROUND: Initiation of enteral feeding is an important part of the best practice model for critically ill patients. Although nasogastric feeding is appropriate for the majority of patients requiring short-term nutrition support, certain patients benefit greatly from postpyloric feeding. OBJECTIVE: To determine which of 2 specialized enteral tube systems achieved postpyloric placement on initial insertion attempt most efficiently. DESIGN: Retrospective study comparing the Tiger 2 tube (T2T) and Cortrak Enteral Access System (C-EAS). SETTING: Academic medical center, mixed intensive care unit (ICU). PATIENTS: All patients admitted to the ICU between 2009 and 2013 who had either a C-EAS or T2T placed. MEASUREMENTS: Success rate for postpyloric placement, congruency of real-time tube placement with x-ray confirmation for C-EAS, and complication rates. RESULTS: Seventy-one T2T and 74 C-EAS patients were included. The T2T was postpyloric 62% (44/71) of attempted placements. C-EAS was postpyloric 43% (32/74) of attempted placements (P = 0.03). C-EAS tracings accurately reflected chest x-ray findings 83% and 82% for postpyloric and non-postpyloric insertion, respectively. During the entire study period, no adverse events were recorded. CONCLUSION: Our institution evaluated 2 different systems designed to ensure postpyloric placement of a small bore feeding tube. No literature exists directly comparing the 2 systems. Our retrospective review, although limited, showed that the T2T was more effective at postpyloric placement on first attempt. Although 1 benefit of the C-EAS system may be real-time visualization, our practice showed this system to be user dependent, which likely led to less success with postpyloric placement.

Massive splenomegaly and lymphopenia: a unique case of obstructive shock.

We present a patient with intravascular large B-cell lymphoma (IVLBCL)-induced obstructive shock. This case represents a unique presentation of the disease, while highlighting the difficulty of establishing the diagnosis. Although there was a high clinical suspicion for a lymphomatous process, the obstructive shock component of the patient's presentation was perplexing. It was not until the autopsy reports demonstrated lymphocytes within the pulmonary vasculature that the clinical picture of altered mental status, weight loss and obstructive shock were unified to the diagnosis of intravascular large B-cell lymphoma.

Use of a protocolized approach to the management of sepsis can improve time to first dose of antibiotics.

PURPOSE: The Surviving Sepsis Guidelines established recommendations for early recognition and rapid treatment of patients with sepsis. Recognizing systemic difficulties that delayed the application of early goal-directed therapy, the Emergency Department and Critical Care leadership instituted a sepsis protocol to identify patients with sepsis and expedite antibiotic delivery. We aimed to determine if the sepsis protocol improved the time to first dose of antibiotics in patients diagnosed with sepsis. MATERIALS AND METHODS: We performed a retrospective chart review of patients with sepsis comparing the time from antibiotic order placement to the first dose of antibiotic therapy over a 3-year period. Patients who received vancomycin and ciprofloxacin underwent additional subgroup analysis, as these antibiotics were made available by protocol for use without infectious disease consultation. RESULTS: The average time to first dose of antibiotics for the presepsis protocol group was 160 minutes, and the average time for the sepsis protocol group was 99 minutes. Fifty-eight patients received vancomycin, and 30 received ciprofloxacin, with a decrease in time of 65 minutes and 41 minutes, respectively. CONCLUSIONS: Initiation of a sepsis protocol, which emphasizes early goal-directed therapy, can improve time to administration of first dose of antibiotics.

Acute onset of tetraparesis, arreflexia and respiratory distress in an otherwise healthy male.

The patient is a previously healthy Eastern-African man in his late 20s, with unknown vaccination status who presented to a US Army Combat Hospital in Iraq with acute upper and lower extremity weakness progressing to respiratory distress requiring intubation over the course of 12 h. His only antecedent symptoms were weakness and nausea. Laboratories including complete blood count, C reactive protein, cerebrospinal fluid analysis, venous blood gas, rapid HIV and chemistry were normal. Non-contrast head CT was normal. The patient was extubated after 24 h but continued to exhibit 2/5 strength in bilateral upper and lower extremities with absence of deep-tendon reflexes. At 48 h of illness it was discovered that the prior to his presentation the patient had a significant life stressor which had since been resolved. Upon discovery that this stressor had been resolved, the patient's symptoms improved over the subsequent 4-6 h and was discharged after 24 h without further complication.

Critical care medicine at Walter Reed Army Medical Center in support of the global war on terrorism.

BACKGROUND: The military medical experience during wartime is unique and distinct from civilian medical practice. Historically, the military has produced innovations resulting in both civilian and military medical care advances, and our current conflict is no different. In this article, we provide a description of the medical and surgical intensive care units at Walter Reed, their history, and approach to new issues encountered in the care of Operation Iraqi Freedom and Operation Enduring Freedom soldiers. Additionally, descriptive statistics regarding the number of Operation Iraqi Freedom and Operation Enduring Freedom soldiers admitted to the critical care service, basic demographics, general category of injury, and discussion of intensive care unit issues unique to this patient population, such as Acinetobacter and traumatic brain injury, are presented. DISCUSSION: We intend to provide a general description of our Operation Iraqi Freedom/Operation Enduring Freedom trauma population cared for by the critical care service at Walter Reed Army Medical Center, as well as a discussion of our approach to caring for some of their unique issues, to detail experiences that could translate into improvements for civilian trauma centers.
