The impact of brief team communication, leadership and team behavior training on ad hoc team performance in trauma care settings.

BACKGROUND: Communication breakdowns and care coordination problems often cause preventable adverse patient care events, which can be especially acute in the trauma setting, in which ad hoc teams have little time for advanced planning. Existing teamwork curricula do not address the particular issues associated with ad hoc emergency teams providing trauma care. METHODS: Ad hoc trauma teams completed a preinstruction simulated trauma encounter and were provided with instruction on appropriate team behaviors and team communication. Teams completed a postinstruction simulated trauma encounter immediately afterward and 3 weeks later, then completed a questionnaire. Blinded raters rated videotapes of the simulations. RESULTS: Participants expressed high levels of satisfaction and intent to change practice after the intervention. Participants changed teamwork and communication behavior on the posttest, and changes were sustained after a 3-week interval, though there was some loss of retention. CONCLUSIONS: Brief training exercises can change teamwork and communication behaviors on ad hoc trauma teams.

Is portable ultrasonography accurate in the evaluation of Schanz pin placement during extremity fracture fixation in austere environments?

OBJECTIVE: The purpose of this study was to investigate the efficacy of ultrasonography to confirm Schanz pin placement in a cadaveric model, and the interobserver repeatability of the ultrasound methodology. DESIGN: This investigation is a repeated measures cadaveric study with multiple examiners. PARTICIPANTS: Cadaveric preparation and observations were done by an orthopaedic traumatologist and resident, and two general surgery traumatologists. INTERVENTIONS: A total of 16 Schanz pins were equally placed in bilateral femora and tibiae. Four examiners took measurements of pin protrusion beyond the distal cortices using first ultrasonography and then by direct measurement after gross dissection. MAIN OUTCOME MEASURE(S): Distal Schanz pin protrusion length measurements from both ultrasonography and direct measurement post dissection. RESULTS: Schanz pin protrusion measurements are underestimated by ultrasonography (p < 0.01) by an average of 10 percent over the range of 5 to 18 mm, and they display a proportional bias that increases the under reporting as the magnitude of pin protrusion increases. Ultrasound data demonstrate good linear correlation and closely represent actual protrusion values in the 5 to 12 mm range. Interobserver repeatability analysis demonstrated that all examiners were not statistically different in their measurements despite minimal familiarity with the ultrasound methodology (p > 0.8). CONCLUSIONS: Despite the statistical imparity of pin protrusion measurement via ultrasound compared to that of gross dissection, a consideration of the clinical relevance of ultrasound measurement bias during an austere operating theatre leads to the conclusion that ultrasonography is an adequate methodology for Schanz pin protrusion measurement.

Professional values, value conflicts, and assessments of the duty-hour restrictions after six years: a multi-institutional study of surgical faculty and residents.

BACKGROUND: the aim of this study was to explore professional values, value conflicts, and assessments of the Accreditation Council for Graduate Medical Education's duty-hour restrictions. METHODS: questionnaires distributed at 15 general surgery programs yielded a response rate of 82% (286 faculty members and 306 residents). Eighteen items were examined via mean differences, percentages in agreement, and significance tests. Follow-up interviews with 110 participants were explored for main themes. RESULTS: residents and faculty members differed slightly with respect to core values but substantially as to whether the restrictions conflict with core values or compromise care. The average resident-faculty member gap for those 13 items was 35 percentage points. Interview evidence indicates consensus over professional values, a gulf between individualistic and team orientations, frequent moral dilemmas, and concerns about the assumption of responsibility by residents and "real-world" training. CONCLUSIONS: the divide between residents and faculty members over conflicts between the restrictions, core values, and patient care poses a significant issue and represents a challenge in educating the next generation of surgeons.

A new professionalism? Surgical residents, duty hours restrictions, and shift transitions.

BACKGROUND: Some anticipated that the Accreditation Council for Graduate Medical Education duty hours restrictions would foster a team-focused "new professionalism" among residents. This study explores the prevalence and challenges of a new professionalism and whether they vary by program size. METHOD: Questionnaires distributed in 15 general surgery programs produced an 82% response rate (N = 306); 52 semistructured follow-up interviews were completed. Results include means, percentage who "agree or strongly agree," significance tests, and main themes from the interviews. RESULTS: A new professionalism is limited by residents' reluctance to pass work from day to night teams, unclear guidance regarding stay-or-go decisions during shift transitions, little educational emphasis on sign-outs, and the practice of long hours in the name of professionalism. Program size is largely unassociated with these beliefs and behaviors. CONCLUSIONS: A new professionalism represents a stalled revolution among surgical residents. The new professionalism's emphasis on teamwork requires additional attention to staffing and workload management.

Pulmonary contusions and critical care management in thoracic trauma.

Many victims of thoracic trauma require ICU care and mechanical ventilatory support. Pressure and volume-limited modes assist in the prevention of ventilator-associated lung injury. Ventilator-associated pneumonia is a significant cause of posttraumatic morbidity and mortality. Minimizing ventilator days, secretion control, early nutritional support, and patient positioning are methods to reduce the risk of pneumonia.

Maximizing reimbursement from trauma response fees (UB-92: 68X) - lessons learned from a hospital comparison.

BACKGROUND: The trauma response fee (UB-92:68x) recently has been approved, to be used by hospitals to cover expenses resulting from continuous trauma team availability. These charges may be made by designated trauma centers for all defined trauma patients when notification has been received before arrival (eligible pt). This study compares two trauma centers' performance in collecting this fee help define methodologies that can enhance reimbursement. METHODS: Our trauma system uses two hospitals (A and B) that are designated as the Level I trauma center for the region on alternate years. This allows hospital performance comparisons with relatively consistent patient demographics, injury severity, and payer mix. Data were collected for a one-year period beginning on January 1, 2003 and included charges, collections, and payer source for the trauma response fee. This time frame allowed the comparison of two six-month sequential periods at each trauma center. RESULTS: Out of a total of 871 trauma patients, 625 were eligible for the trauma response fee (72%): hospital A = 65% and hospital B = 77%. Total trauma response fee charges for both centers were 1,111,882 dollars with collections of 319,684 dollars (28.8%). The following payer sources contributed to the collections: Indemnity insurance (77.4%), Managed Care (22.1%), Medicare (0.3%), and Medicaid (0.2%). No collections were obtained from any self-pay patient. Eligible patients were charged a trauma response fee much less frequently in Hospital A than B (29.35% versus 95.2%) but revenue / charge ratios were equivalent at both hospitals (0.32 versus 0.28). These differences resulted in markedly enhanced revenue for each eligible patient in Hospital B compared with A (735 dollars versus 174 dollars) CONCLUSIONS: Enhanced collection by hospital B was a result of a higher charge, compulsive billing of all eligible patients, and emphasis on pre-admission designation of trauma patients. Effective billing and collection process related to trauma response fees results in substantial additional revenue for the trauma center without additional expense.

Complete occlusion after blunt injury to the abdominal aorta.

BACKGROUND: Injury to the abdominal aorta after blunt trauma is uncommon. When this injury results in complete vessel occlusion, the presentation is dramatic. Timely intervention is essential. METHODS: After a case report, we examined all reported cases of complete occlusion after blunt injury to the abdominal aorta and reviewed the cause, presentation, and management of this injury. RESULTS: Complete vessel occlusion arises from intimal injury. The most frequent mechanism is compression from a seat belt or steering wheel during a motor vehicle crash. Patients present with absent femoral and distal pulses in association with lower extremity neuropathy. Intervention commonly involves bypass grafting of the abdominal aorta. CONCLUSION: Complete occlusion after blunt trauma to the abdominal aorta is rare. Neurologic deficits most commonly arise from peripheral nerve ischemia. Reperfusion within 6 hours confers a greater chance of limb salvage and neurologic recovery.

A new method of continuous venovenous rewarming.

PURPOSE: Hypothermia is a significant problem in medicine and is part of a deadly triad, including hypothermia, acidosis, and coagulopathy. Multiple methods of rewarming are used to treat moderate hypothermia. The purpose of this study was to compare the effectiveness of continuous venovenous rewarming (CVVR) using the FMS 2000 (Belmont Instrument Corp., Billerica, Massachusetts) in conjunction with external rewarming techniques versus external rewarming alone in the porcine model. METHODS: Ten subject animals, each weighing approximately 40 kg, were evenly divided and randomly assigned to either a control group using external rewarming techniques alone or the CVVR group utilizing the FMS 2000 in addition to the external rewarming techniques used in the control group. Hypothermia was induced in the swine model using cold water immersion to achieve a core temperature of 30 degrees C. Both esophageal and rectal temperature probes were used to monitor and record core body temperatures every 15 minutes during the experiment. Each study animal was then rewarmed until a core temperature of at least 37 degrees C was recorded in both the esophageal and rectal probes. The animals were observed clinically for 3 days after the study. RESULTS: The average time required to rewarm the control group was 253 minutes, compared with 113 minutes in the CVVR group. After 30 minutes of rewarming, the difference between the 2 groups with respect to core temperature was statistically significant (p = 0.002). A drop in core temperature after the initiation of rewarming, or after-drop, was noted in the control group animals, but not in the CVVR group. This difference was statistically significant after 15 minutes of rewarming (p = 0.015) CONCLUSIONS: Venovenous rewarming utilizing the FMS 2000 fluid management system is more effective than is standard therapy alone for rewarming in the moderately hypothermic porcine model. This finding may prove clinically useful in the treatment of patients suffering from moderate hypothermia.
