Violence Prevention Programs Are Effective When Initiated During the Initial Workup of Patients in an Urban Level I Trauma Center.

This study represents the first attempt at evaluating the ability of the CureViolence Hospital-Response Intervention Program (previously CeaseFire) to disrupt the pattern of violent reinjury. The clinical data points of 300 African American men who presented to our trauma center with a gunshot wound and received intervention at the bedside between 2005 and 2007 (with a 48-month follow-up) were collected. This cohort was matched with a post hoc historical control group using hospital records from 2003 to 2005. The mean age for both groups was 23.9 years. Odds ratios and 95% confidence intervals were obtained. Using a binary logistical regression model, we assessed the performance of three variables of interest: age at the time of the initial injury, treatment group, and initial disposition group to predict recidivism. We utilized the Nagelkerke R square method, which described the proportion of the variance of the reinjury rate and validated our findings using the Hosmer-Lemeshow test (for goodness-of-fit). Six percent (n = 18) of subjects in the treatment group and 11% (n = 33) in the control group returned with a new injury, yielding a total reinjury rate of 8.5%. Most patients returned only once with another violent injury. Individuals who did not receive CureViolence services were nearly twice as likely (odds ratio = 1.94; 95% confidence interval = 1.065, 3.522) to return with a violent reinjury. This finding suggests that Hospital-Response Intervention Programs (HRIP) have a protective effect in violently injured patients. We therefore conclude our HRIP positively affected at-risk patients and prevented violent reinjury.

Traumatic abdominal wall hernias: a single-center case series of surgical management.

BACKGROUND: Traumatic abdominal wall hernias (TAWHs) are a rare clinical entity that can be difficult to diagnose and manage. There is no consensus on management of TAWH due to its low incidence and complex concomitant injury patterns. We hereby present the largest single-center case series in the USA to characterize associated injury patterns, identify optimal strategies for hernia management, and determine outcomes. METHODS: Patients who presented with a TAWH from blunt trauma requiring operative management were retrospectively identified over a 14-year period. Demographic data, Injury Severity Score (ISS), associated injuries, type of repair, durability of repair, and complications were collected, and descriptive statistics were calculated. RESULTS: Fifteen patients were identified. The average age was 31±11 years, ISS 15±9, and body mass index 33.4±7.1 kg/m2. Mechanisms included falls (13%), motor vehicle collisions (60%), motorcycle accidents (20%), and pedestrian versus motor vehicle collisions (7%). The most commonly associated injuries included colonic injuries (53%), long bone fractures (47%), pelvic fractures (40%), and small bowel injuries (33%). Nineteen hernia repairs were performed: 6 underwent primary suture repair (32%) and 13 used mesh (68%). There were four recurrences. We could not find any significant relationship between contamination and mesh use or recurrence. There was one mortality related to sepsis. DISCUSSION: TAWHs have an associated injury pattern involving fractures and abdominopelvic visceral injuries where a tailored approach is advisable. Without hollow viscous injuries and gross contamination, these hernias can be repaired safely with mesh in the acute setting. However, in patients with gross contamination or hemodynamic instability, the risk of recurrence with primary repair must be weighed against the risk of infection and prolonged surgery with mesh repair. In those cases, a delayed reconstruction in the elective setting may be optimal.

Trends in demographics and outcome of patients presenting with traumatic brain injury.

OBJECTIVE: To analyze the trends in demographics and outcomes of patients presenting with traumatic brain injury by performing a retrospective database review of the Illinois Department of Public Health (IDPH) Trauma Registry. METHODS: We utilized the IDPH Trauma Registry to retrieve data on patients treated for traumatic brain injuries at our large, tertiary care hospital from 2004 to 2012, inclusive. From this data, logistic regression models were used to analyze and compare basic demographics such as age, sex, and clinical outcome. RESULTS: Three thousand and thirty-nine patients were analyzed with a mean age of 43 (standard deviation, 24) and a median age of 41 (interquartile range, 23 to 60). Over the study period, patients' age increased steadily from 32 to 49 years. The percentage of female patients increased, from 16.4% to 27.5% over the last 4 years. Overall mortality was greater for males than females (22.1% vs. 17.3%; odds ratio [OR], 1.36; 95% confidence interval [CI], 1.10 to 1.68). Mortality decreased over the period (OR, 0.88; 95% CI, 0.85 to 0.91), with a greater decrease in females (OR, 0.84; 95% CI, 0.78 to 0.90) than in males (OR, 0.90; 95% CI, 0.86 to 0.94). CONCLUSION: Although the age of patients presenting with traumatic brain injury is increasing substantially, the data suggests that overall mortality appears to be decreasing, and this decrease appears to be greater in females than in males. These changes in trends found in the IDPH Trauma Registry supports the importance for further analysis of other reliable public datasets to identify areas of future study.

Tree stands, not guns, are the midwestern hunter's most dangerous weapon.

Although the prevailing stereotype is that most hunting injuries are gunshot wounds inflicted by intoxicated hunting buddies, our experience led us to hypothesize that falls comprise a significant proportion of hunting related injuries. Trauma databases of two Level I trauma centers in central Ohio were queried for all hunting related injuries during a 10-year period. One hundred and thirty patients were identified (90% male, mean age 41.0 years, range 17-76). Fifty per cent of injuries resulted from falls, whereas gunshot wounds accounted for 29 per cent. Most hunters were hunting deer and 92 per cent of falls were from tree stands. Alcohol was involved in only 2.3 per cent, and drugs of abuse in 4.6 per cent. Of gunshots, 58 per cent were self-inflicted, and 42 per cent were shot by another hunter. Tree stand falls were highly morbid, with 59 per cent of fall victims suffering spinal fractures, 47 per cent lower extremity fractures, 18 per cent upper extremity fractures, and 18 per cent closed head injuries. Surgery was required for 81 per cent of fall-related injuries, and 8.2 per cent of fall victims had permanent neurological deficits. In contrast to prevailing beliefs, in our geographic area tree-stand falls are the most common mechanism of hunting related injury requiring admission to a Level 1 trauma center.

Missed surgical intensive care unit billing: potential financial impact of 24/7 faculty presence.

BACKGROUND: To efficiently capture evaluation and management (E&M) and procedural billing in our surgical intensive care unit (SICU), we have developed an electronic billing system that links to the electronic medical record (EMR). In this system, only notes electronically signed and coded by an attending generate billing charges. We hypothesized that capture of missed billing during nighttime and weekends might be sufficient to subsidize 24/7 in-house attending coverage. METHODS: A retrospective chart EMR review was performed of the EMRs for all SICU patients during a 2-month period. Note type, date, time, attending signature, and coding were analyzed. Notes without attending signature, diagnosis, or current procedural terminology (CPT) code were considered incomplete and identified as "missed billing." RESULTS: Four hundred and forty-three patients had 465 admissions generating 2,896 notes. Overall, 76% of notes were signed and coded by an attending and billed. Incomplete (not billed) notes represented an overall missed billing opportunity of $159,138 for the 2-month time period (approximately $954,000 annually). Unbilled E&M encounters during weekdays totaled $54,758, whereas unbilled E&M and procedures from weeknights and weekends totaled $88,408 ($44,566 and $43,842, respectively). Missed billing after-hours thus represents approximately $530K annually, extrapolating to approximately $220K in collections from our payer mix. Surprisingly, missed E&M and procedural billing during weekdays totaled $70,730 (approximately $425K billing, approximately $170K collections annually), and typically represented patients seen, but transferred from the SICU before attending documentation was completed. CONCLUSIONS: Capture of nighttime and weekend ICU collections alone may be insufficient to add faculty or incentivize in-house coverage, but could certainly complement other in-house derived revenues to such ends. In addition, missed daytime billing in busy modern ICUs can be substantial, and use of an EMR to identify missed billing opportunities can help create solutions to recover these revenues.

Trigger for intercellular adhesion molecule-1 expression in rat lungs transplanted from non-heart-beating donors.

BACKGROUND: Lung transplantation from non-heart-beating donors causes ischemia-reperfusion injury. We sought to determine the trigger for expression of intercellular adhesion molecule-1 (ICAM-1) caused by ischemia-reperfusion injury. METHODS: Thirty-six Sprague-Dawley rats underwent left lung transplant (six groups of 6). Lungs were transplanted immediately after arrest, or from non-heart-beating donors after 2 hours of oxygen-ventilation or no ventilation. Recipients were reperfused for 4 or 6 hours, then lungs were stained with a mouse anti-rat ICAM-1 monoclonal antibody, developed with avidin-biotin peroxidase to a biotinylated anti-mouse immunoglobin G antibody. Intercellular adhesion molecule-1 expression was graded by two masked observers as 0 = absent, 1 = weak, or 2 = strong in alveoli, arterioles, and venules. Explanted recipient left lungs served as negative controls, and positive controls were generated 6 hours after intraperitoneal injection of endotoxin. Intercellular adhesion molecule-1 expression above baseline among groups was compared by Fisher's exact test. RESULTS: Constitutive expression of ICAM-1 was present in rat lung alveoli, with 24 of 35 controls staining weakly and 4 of 35 strongly positive in alveolar areas. Intercellular adhesion molecule-1 expression was not increased in transplanted lungs evaluated after 4 hours of reperfusion, even lungs retrieved from non-heart-beating donors. But when non-heart-beating donor lungs were assessed 6 hours after onset of reperfusion, ICAM-1 expression was significantly more apparent in alveolar and arteriolar areas, compared with controls and lungs transplanted immediately after arrest. CONCLUSIONS: Lungs transplanted immediately after circulatory arrest do not sustain sufficient ischemia-reperfusion injury to upregulate ICAM-1. Onset of reperfusion is the signal for ICAM-1 expression, not the onset of ischemia or the total duration of ischemic and reperfusion time together. Strategies at reperfusion may minimize ICAM-1 expression.
