Operative vs Nonoperative Management of Pediatric Blunt Pancreatic Trauma: Evaluation of the National Trauma Data Bank.

BACKGROUND: Traumatic pancreatic injury is associated with significant morbidity and mortality. We evaluated the differences in outcomes among children with blunt pancreatic injuries managed operatively and nonoperatively. STUDY DESIGN: The National Trauma Data Bank was evaluated from 2002 to 2011. Patients less than18 years of age with blunt pancreatic injuries and Abbreviated Injury Scale (AIS) scores ≥ 3 were identified. Patients were divided into nonoperative (NO), operative (O), and delayed operative (DO; operation performed 48 hours or more after admission) groups. Outcomes evaluated were total length of stay (LOS), ICU use/LOS, complications, and death. Univariate comparisons were performed using Fisher's exact and Kruskal-Wallis rank tests. Multivariable analyses were performed using robust regression and logistic regression. RESULTS: There were 424 cases analyzed. Mean (± SD) age was 10.6 ± 5.3 years, and mean Injury Severity Score (ISS) was 23.4 ± 13.4. Operative groups differed by age (p = 0.002), AIS severity (p = 0.04), and concomitant head injury (p = 0.01), but were similar with regard to sex, race, and ISS. Length of stay was significantly higher in the DO group compared with the NO or O groups; the NO group had the lowest LOS (covariate-adjusted: 18.7 days vs 11.8 days, p < 0.001 and 12.6 days, p < 0.001, respectively) and infection rates (10.2% vs 1.6% and 6.2%, respectively, p = 0.04). The ICU LOS was greatest in the DO group (vs NO, p = 0.03; O, p = 0.29), as was the likelihood of ICU use (vs NO, p = 0.02; O, p = 0.75). Groups did not differ with respect to outcomes including death (p = 0.94) and overall complication rate (p = 0.63). CONCLUSIONS: Overall, children managed nonoperatively have equivalent or better outcomes when compared with operative and delayed operative management in regard to death, overall complications, LOS, ICU LOS, and ICU use.

Guns and states: pediatric firearm injury.

BACKGROUND: A recent report indicates that firearm-related injuries are responsible for 30% of pediatric trauma fatality. The literature is however limited in examining pediatric firearm injuries and variations in state gun control laws. Therefore, we sought to examine the association between pediatric firearm injuries and the Stand-Your-Ground (SYG) and Child Access Protection (CAP) laws. METHODS: All pediatric (age, 0-20 years) hospitalizations with firearm injuries were identified from the Kids' Inpatient Database from 2006 and 2009. States were compared for SYG and CAP laws. RESULTS: A total of 19,233 firearm injury hospitalizations were identified, with 64.7% assault, 27.2% accidental, and 3.1% suicide injury. Demographics for assault injury were as follows: mean age of 17.6 years, 88.4% male, 44.4% black, 18.2% Hispanic, 70.5% from metropolitan areas, and 50.1% from the poorest median income neighborhoods. Suicide injury cases were more likely to be white (57.8% vs. 16.6%, p < 0.001) and female (15.1% vs. 9.8%, p < 0.001). States with the SYG law were associated with increased accidental injury (odds ratio [OR], 1.282; p < 0.001). There was no statistical association between CAP law and the incidence of accidental injury or suicide. Multivariate logistic regression analysis found other predictive demographic factors for firearm injury: black (OR, 6.164), urban areas (OR, 1.557), poorest median income neighborhoods (OR, 2.785), male (OR, 28.602), and 16 years or older (OR, 37.308). Total economic burden was estimated at more than $1 billion dollars, with a median length of stay of 3 days, 8.4% discharge to rehabilitation, and 6.2% in-hospital mortality. CONCLUSION: Pediatric firearm injuries continue to be a significant source of morbidity, mortality, and economic burden. A significant increase in accidental firearm injuries in states with the SYG law may highlight inadvertent effects of the law. Race, sex, and median income are additional contributing factors. Advocacy and focused educational efforts for specific socioeconomic and racial groups may potentially reduce firearm injuries. LEVEL OF EVIDENCE: Prognostic study, level II.

Boot cAMP: educational outcomes after 4 successive years of preparatory simulation-based training at onset of internship.

PURPOSE: Preparatory training for new trainees beginning residency has been used by a variety of programs across the country. To improve the clinical orientation process for our new postgraduate year (PGY)-1 residents, we developed an intensive preparatory training curriculum inclusive of cognitive and procedural skills, training activities considered essential for early PGY-1 clinical management. We define our surgical PGY-1 Boot Camp as preparatory simulation-based training implemented at the onset of internship for introduction of skills necessary for basic surgical patient problem assessment and management. This orientation process includes exposure to simulated patient care encounters and technical skills training essential to new resident education. We report educational results of 4 successive years of Boot Camp training. Results were analyzed to determine if performance evidenced at onset of training was predictive of later educational outcomes. METHODS: Learners were PGY-1 residents, in both categorical and preliminary positions, at our medium-sized surgical residency program. Over a 4-year period, from July 2007 to July 2010, all 30 PGY-1 residents starting surgical residency at our institution underwent specific preparatory didactic and skills training over a 9-week period. This consisted of mandatory weekly 1-hour and 3-hour sessions in the Simulation Center, representing a 4-fold increase in time in simulation laboratory training compared with the remainder of the year. Training occurred in 8 procedural skills areas (instrument use, knot-tying, suturing, laparoscopic skills, airway management, cardiopulmonary resuscitation, central venous catheter, and chest tube insertion) and in simulated patient care (shock, surgical emergencies, and respiratory, cardiac, and trauma management) using a variety of high- and low-tech simulation platforms. Faculty and senior residents served as instructors. All educational activities were structured to include preparatory materials, pretraining briefing sessions, and immediate in-training or post-training review and debriefing. Baseline cognitive skills were assessed with written tests on basic patient management. Post-Boot Camp tests similarly evaluated cognitive skills. Technical skills were assessed using a variety of task-specific instruments, and expressed as a mean score for all activities for each resident. All measurements were expressed as percent (%) best possible score. Cognitive and technical performance in Boot Camp was compared with subsequent clinical and core curriculum evaluations including weekly quiz scores, annual American Board of Surgery In-Training Examination (ABSITE) scores, program in-training evaluations (New Innovations, Uniontown, Ohio), and operative assessment instrument scores (OP-Rate, Baystate Medical Center, Springfield, Massachusetts) for the remainder of the PGY-1 year. RESULTS: Performance data were available for 30 PGY-1 residents over 4 years. Baseline cognitive skills were lower for the first year of Boot Camp as compared with subsequent years (71 ± 13, 83 ± 9, 84 ± 11, and 86 ± 6, respectively; p = 0.028, analysis of variance; ANOVA). Performance improved between pretests and final testing (81 ± 11 vs 89 ± 7; p < 0.001 paired t test). There was statistically significant correlation between Boot Camp final cognitive test results and American Board of Surgery In-Training Examination scores (p = 0.01; n = 22), but not quite significant for weekly curriculum quiz scores (p = 0.055; n = 22) and New Innovations cognitive assessments (p = 0.09; n = 25). Statistically significant correlation was also noted between Boot Camp mean overall skills and New Innovations technical skills assessments (p = 0.002; n = 25) and OP-Rate assessments (p = 0.01; n = 12). CONCLUSIONS: Individual simulation-based Boot Camp performance scores for cognitive and procedural skills assessments in PGY-1 residents correlate with subjective and objective clinical performance evaluations. This concurrent correlation with multiple traditional evaluation methods used to express competency in our residency program supports the use of Boot Camp performance measures as needs assessment tools as well as adjuncts to cumulative resident evaluation data.

Blunt pancreatoduodenal injury: a multicenter study of the Research Consortium of New England Centers for Trauma (ReCONECT).

OBJECTIVES: To evaluate the safety of nonoperative management (NOM), to examine the diagnostic sensitivity of computed tomography (CT), and to identify missed diagnoses and related outcomes in patients with blunt pancreatoduodenal injury (BPDI). DESIGN: Retrospective multicenter study. SETTING: Eleven New England trauma centers (7 academic and 4 nonacademic). PATIENTS: Two hundred thirty patients (>15 years old) with BPDI admitted to the hospital during 11 years. Each BPDI was graded from 1 (lowest) to 5 (highest) according to the American Association for the Surgery of Trauma grading system. MAIN OUTCOME MEASURES: Success of NOM, sensitivity of CT, BPDI-related complications, length of hospital stay, and mortality. RESULTS: Ninety-seven patients (42.2%) with mostly grades 1 and 2 BPDI were selected for NOM: NOM failed in 10 (10.3%), 10 (10.3%) developed BPDI-related complications (3 in patients in whom NOM failed), and 7 (7.2%) died (none related to failure of NOM). The remaining 133 patients were operated on urgently: 34 (25.6%) developed BPDI-related complications and 20 (15.0%) died. The initial CT missed BPDI in 30 patients (13.0%); 4 of them (13.3%) died but not because of the BPDI. The mortality rate in patients without a missed diagnosis was 8.8% (P = .50). There was no correlation between time to diagnosis and length of hospital stay (Spearman r = 0.06; P = .43). The sensitivity of CT for BPDI was 75.7% (76% for pancreatic and 70% for duodenal injuries). CONCLUSIONS: The NOM of low-grade BPDI is safe despite occasional failures. Missed diagnosis of BPDI continues to occur despite advances in CT but does not seem to cause adverse outcomes in most patients.

Delayed closure of ventral abdominal hernias after severe trauma.

BACKGROUND: Primary closure after trauma celiotomies is not always accomplished. We reviewed our experience with delayed closure in trauma patients. METHODS: Prospective data were collected on patients who had damage-control celiotomy and were discharged with open abdomens. The time to closure, repair methods, and complication data also were compiled. RESULTS: In the 6-year period, 84 patients underwent damage-control celiotomy. Thirty-one patients died and 33 patients had early closure. Twenty patients had closure during a subsequent hospitalization (mean time to delayed closure, 193 days): 8 patients (40%) had component separation, 3 (15%) had component separation with mesh, 4 (20%) had mesh alone, and primary closure occurred in 5 (25%). Nine patients (45%) had complications such as wound and mesh infections, hernias, and fistulas. Repair before or after 6 months showed no statistically significant difference for the presence of complications or enterotomies (P = .64 and .5743, respectively). CONCLUSIONS: Open-abdomen reconstruction presents significant challenges. Closure within 6 months is possible; the presence of complications is not affected by early repair.
