Trauma video review utilization: A survey of practice in the United States.

INTRODUCTION: Trauma video review (TVR) for quality improvement and education in the United States has been described for nearly three decades. The most recent information on this practice indicated a declining prevalence. We hypothesized that TVR utilization has increased since most recent estimates. METHODS: We conducted a survey of TVR practices at level I and level II US trauma centers. We distributed an electronic survey covering past, current, and future TVR utilization to the Eastern Association for the Surgery of Trauma membership. RESULTS: 45.0% of US level I and level II trauma centers completed surveys. 71/249 centers (28.5%) had active TVR programs. The use of TVR did not differ between level I and level II centers (28.8% vs. 27.8%, p = 0.87). Respondents using TVR were overwhelmingly positive about its perception (median score 8, [IQR 6-9]; 10 = 'best') at their institutions. CONCLUSIONS: TVR use at Level I centers has increased over the past decade. Increased TVR utilization may form the basis for multicenter studies comparing processes of care during trauma resuscitation.

Emergency Department Versus Operating Suite Intubation in Operative Trauma Patients: Does Location Matter?

BACKGROUND: Decreasing the time from patient arrival to definitive surgical care in injured patients requiring an operation improves outcomes. We sought to study the effect of intubation location (emergency department versus operating suite) on time to definitive surgical care. We hypothesized that patients requiring emergency surgical interventions intubated in the emergency department would have shorter times to definitive care when compared to patients intubated in the operating suite. METHODS: All injured patients with a preoperative emergency department dwell time of less than 30 min and undergoing emergency operative procedures with the trauma surgery service at an urban Level I center (2010-2017) were analyzed. Demographics, clinical variables, and outcomes were assessed in relation to emergency department intubation versus operating suite intubation. The primary study endpoint was time to initiation of definitive surgical care, defined as the total elapsed time from emergency department arrival until operating room incision time. To investigate the relationship between clinical variables and time, multivariable regression was performed. RESULTS: In total, 241 patients were included. In total, 138 patients were intubated in the emergency department and 103 patients were intubated in the operative suite. There was no difference between patients intubated in the emergency department and those intubated in the operating room with respect to age, gender, injury mechanism, initial heart rate or systolic blood pressure. Emergency department patients were more likely to sustain post-intubation, traumatic cardiopulmonary arrest (8.0 vs. 0.9%; p = 0.014). No statistical difference in total elapsed time from arrival to definitive surgical care was appreciated between study groups (41 vs. 43 min; p = 0.064). After controlling for clinical variables, emergency department intubation was not associated with time to definitive care (p = 0.386) in the multiple variable regression analysis. CONCLUSION: When emergency department and operative suite intubation patients were compared, emergency department intubation did not decrease total elapsed time until definitive surgery but was associated with post-intubation, traumatic cardiopulmonary arrest.

The relationship between processes and outcomes for injured older adults: a study of a statewide trauma system.

PURPOSE: Age is a risk factor for death, adverse outcomes, and health care use following trauma. The American College of Surgeons' Trauma Quality Improvement Program (TQIP) has published "best practices" of geriatric trauma care; adoption of these guidelines is unknown. We sought to determine which evidence-based geriatric protocols, including TQIP guidelines, were correlated with decreased mortality in Pennsylvania's trauma centers. METHODS: PA's level I and II trauma centers self-reported adoption of geriatric protocols. Survey data were merged with risk-adjusted mortality data for patients ≥65 from a statewide database, the Pennsylvania Trauma Systems Foundation (PTSF), to compare mortality outlier status and processes of care. Exposures of interest were center-specific processes of care; outcome of interest was PTSF mortality outlier status. RESULTS: 26 of 27 eligible trauma centers participated. There was wide variation in care processes. Four trauma centers were low outliers; three centers were high outliers for risk-adjusted mortality rates in adults ≥65. Results remained consistent when accounting for center volume. The only process associated with mortality outlier status was age-specific solid organ injury protocols (p = 0.04). There was no cumulative effect of multiple evidence-based processes on mortality rate (p = 0.50). CONCLUSIONS: We did not see a link between adoption of geriatric best-practices trauma guidelines and reduced mortality at PA trauma centers. The increased susceptibility of elderly to adverse consequences of injury, combined with the rapid growth rate of this demographic, emphasizes the importance of identifying interventions tailored to this population. LEVEL OF EVIDENCE: III. STUDY TYPE: Descriptive.

Loop versus end colostomy reversal: has anything changed?

PURPOSE: Though primary repair of colon injuries is preferred, certain injury patterns require colostomy creation. Colostomy reversal is associated with significant morbidity and healthcare cost. Complication rates may be influenced by technique of diversion (loop vs. end colostomy), though this remains ill-defined. We hypothesized that reversal of loop colostomies is associated with fewer complications than end colostomies. METHODS: This is a retrospective, multi-institutional study (four, level-1 trauma centers) of patients undergoing colostomy takedown for trauma during the time period 1/2006-12/2012. Data were collected from index trauma admission and subsequent admission for reversal and included demographics and complications of reversal. Student's t test was used to compare continuous variables against loop versus end colostomy. Discrete variables were compared against both groups using Chi-squared tests. RESULTS: Over the 6-year study period, 218 patients underwent colostomy takedown after trauma with a mean age of 30; 190 (87%) were male, 162 (74%) had penetrating injury as their indication for colostomy, and 98 (45%) experienced at least one complication. Patients in the end colostomy group (n = 160) were more likely to require midline laparotomy (145 vs. 18, p < 0.001), had greater intra-operative blood loss (260.7 vs. 99.4 mL, p < 0.001), had greater hospital length of stay (8.4 vs. 5.5 days, p < 0.001), and had more overall complications (81 vs. 17, p = 0.005) than patients managed with loop colostomy (n = 58). CONCLUSIONS: Local takedown of a loop colostomy is safe and leads to shorter hospital stays, less intra-operative blood loss, and fewer complications when compared to end colostomy.

Penetrating torso injuries in older adults: increased mortality likely due to "failure to rescue".

PURPOSE: Approximately 8 % of injuries in the elderly are from penetrating mechanisms. The natural history of potentially survivable penetrating torso wounds in the elderly is not well studied. Older adults with penetrating injuries to the torso may have worse outcomes than matched, younger patients due to a failure to rescue after complications. METHODS: A retrospective chart review of all patients ≥55 (older) with a penetrating injury (GSW or SW) to the torso over 20 years was performed. All patients with a maximum AIS chest or abdomen >1 and <6 were included. A matched cohort (mechanism, AIS chest and abdomen, ISS and sex) of patients between the ages of 20-40 years (young) was created (3 young, 1 older). Differences in hemodynamics, complications, length of stay and mortality were analyzed. RESULTS: 105 older met inclusion criteria were compared to 315 young patients. Hemodynamic status was similar between the groups. Older patients required ICU care more often than younger patients, p < 0.05. Older patients required longer ICU stays, p < 0.001 and longer hospitalizations, p = 0.0012. More older patients (41.0 %) suffered post-injury complications compared to the young (26.4 %), p = 0.005. Older patients who suffered a complication had a higher mortality (30.2 %) than the young after a complication (10.8 %), p = 0.007. CONCLUSIONS: While uncommon, penetrating injuries to older adults are associated with higher rates of post-injury complications and increased mortality. This may represent a "failure to rescue" and represent an opportunity for improved post-injury care in older adults who suffer potentially survivable penetrating torso injuries.

Initial venous lactate levels in patients with isolated penetrating extremity trauma: a retrospective cohort study.

INTRODUCTION: Elevated initial lactate levels have been shown to be associated with severe injury in trauma patients, but some patients who do not appear to be in shock also presented with elevated lactate levels. We hypothesized that in hemodynamically stable patients with isolated penetrating extremity trauma, initial lactate level does not predict clinically significant bleeding. METHODS: A 5-year institutional database review was performed. Hemodynamically stable patients (HR < 101, SBP > 90) with isolated penetrating extremity trauma with an initial lactate sent were included. The exposure of interest was captured as a dichotomous variable by initial lactate level normal (N ≤ 2.2 mEq/L), elevated (E > 2.2 mEq/L). The primary outcome measurement was clinically significant bleeding, defined by need for intervention (operation, angioembolization, or transfusion) or laboratory evidence of bleeding (presenting Hg < 7 g/dL, or Hg decrease by >2 g/dL/24 h). Chi-squared and Mann-Whitney tests were used to compare variables. RESULTS: A total of 132 patients were identified. There were no differences in demographics or mechanism of injury between the N (n = 43, 7%) and E (n = 89, 14%) groups. Median lactate levels were 1.6 (IQR 1.2-1.9) mEq/dL vs. 3.8 (IQR 2.8-5.2) in the N and E groups, p < 0.001. Lactate was elevated in 89 (67%) patients but was not associated with clinically significant bleeding (37% elevated vs. 39 % not elevated p = 0.82). CONCLUSIONS: In hemodynamically stable patients with isolated penetrating trauma to the extremity, elevated initial venous lactate levels (>2.2 mEq/L) are not associated with bleeding or need for interventions. Clinical judgment remains the gold standard for evaluation and management of these patients.

Psoas:lumbar vertebra index: central sarcopenia independently predicts morbidity in elderly trauma patients.

INTRODUCTION: Central sarcopenia as a surrogate for frailty has recently been studied as a predictor of outcome in elderly medical patients, but less is known about how this metric relates to outcomes after trauma. We hypothesized that psoas:lumbar vertebral index (PLVI), a measure of central sarcopenia, is associated with increased morbidity and mortality in elderly trauma patients. METHODS: A query of our institutional trauma registry from 2005 to 2010 was performed. Data was collected prospectively for the Pennsylvania Trauma Outcomes Study (PTOS). INCLUSION CRITERIA: age >55 years, ISS >15, and ICU LOS >48 h. Using admission CT scans, psoas:vertebral index was computed as the ratio between the mean cross-sectional areas of the psoas muscles and the L4 vertebral body at the level of the L4 pedicles. The 50th percentile of the psoas:L4 vertebral index value was determined, and patients were grouped into high (>0.84) and low (≤0.83) categories based on their relation to the cohort median. Primary endpoints were mortality and morbidity (as a combined endpoint for PTOS-defined complications). Univariate logistic regression was used to test the association between patient factors and mortality. Factors found to be associated with mortality at p < 0.1 were entered into a multivariable model. RESULTS: A total of 180 patients met the study criteria. Median age was 74 years (IQR 63-82), median ISS was 24 (IQR 18-29). Patients were 58 % male and 66 % Caucasian. Mean PLVI was 0.86 (SD 0.25) and was higher in male patients than female patients (0.91 ± 0.26 vs. 0.77 ± 0.21, p < 0.001). PLVI was not associated with mortality in univariate or multivariable modeling. After controlling for comorbidities, ISS, and admission SBP, low PLVI was found to be strongly associated with morbidity (OR 4.91, 95 % CI 2.28-10.60). CONCLUSIONS: Psoas:lumbar vertebral index is independently and negatively associated with posttraumatic morbidity but not mortality in elderly, severely injured trauma patients. PLVI can be calculated quickly and easily and may help identify patients at increased risk of complications.

Effect of insurance status on patients admitted for acute diverticulitis.

AIM: The study aimed to evaluate the relationship between insurance status and the management and outcome of acute diverticulitis in a nationally representative sample. METHOD: A retrospective cohort analysis of a nationally representative sample of 1 031 665 hospital discharges of patients admitted for acute diverticulitis in the 2006-2009 Nationwide Inpatient Sample (NIS), Healthcare Cost and Utilization Project data set. The main outcome measures included state at presentation (complicated/uncomplicated), management (medical/surgical), time to surgical intervention, type of operation and inpatient death. RESULTS: In total, 207 838 discharges were identified (including 37.0% with private insurance, 49.3% in Medicare, 5.6% in Medicaid and 5.8% uninsured) representing 1 031 665 total discharges nationally. Medicare patients were more likely to present with complicated diverticulitis compared with private insurance patients (23.8% vs 15.1%). Time to surgical intervention differed by insurance status. After adjusting for patient, hospital and treatment factors, Medicare patients were less likely than those with private insurance to undergo a procedure (Medicare OR = 0.86, 95% CI: 0.82-0.91), while the uninsured were more likely to undergo drainage (OR = 1.30, 95% CI: 1.16-1.46) or a colostomy only (OR = 1.70, 95% CI: 1.24-2.33). All patients without private insurance were more likely to die in hospital (Medicare OR = 1.29, 95% CI: 1.09-1.52; Medicaid OR = 1.55, 95% CI: 1.22-1.97; uninsured OR = 1.41, 95% CI: 1.07-1.87). CONCLUSION: In a nationally representative sample of patients with acute diverticulitis, patient management and outcome varied significantly by insurance status, despite adjustment for potential confounders. Providers might need to heighten surveillance for complications when treating patients without private insurance to improve outcome.

Clinical outcomes following invasive versus noninvasive preoperative stabilization of closed diaphyseal femur fractures.

BACKGROUND: The use of invasive traction (INV-T) to stabilize femur fractures prior to fixation (open reduction and internal fixation, ORIF) remains controversial. Some centers have utilized noninvasive traction (NINV-T) or splinting preoperatively. It is possible that INV-T decreases hemorrhage. However, the use of INV-T in pediatric patients and for femoral neck fractures in adults is associated with worsened outcomes. We hypothesized that there is no difference in the need for transfusion between those who receive INV-T and NINV-T. METHODS: A retrospective study was performed at two level I and one level II trauma center from January 2006 to December 2009. Patients ≥18 years with a closed diaphyseal femur fracture who underwent ORIF within 48 h of arrival were included. Patients were grouped by method of preoperative fracture stabilization. Primary endpoint was need for transfusion. A power analysis found that 94 patients were needed to detect a 25 % difference with 80 % power. RESULTS: Fifty-six (22 %) received INV-T and 199 (78 %) received NINV-T stabilization. No significant differences were found between groups in terms of age, injury severity score, or ORIF method. There was no significant difference between the two groups in the hemoglobin value on arrival, preoperative hemoglobin value, or the difference between admission and preoperative hemoglobin values. We did not find a significant difference in the need for red blood cell transfusion between the two groups. There was no difference in length of stay or discharge destination. CONCLUSION: INV-T is not associated with improved outcomes in adult patients with closed mid-shaft femoral fractures who are operated upon within 48 h of arrival.
