The utility of presacral drainage in penetrating rectal injuries in adult and pediatric patients.

BACKGROUND: With changing weaponry associated with injuries in civilian trauma, there is no clinical census on the utility of presacral drainage (PSD) in penetrating rectal injuries (PRIs), particularly in pediatric patients. METHODS: Patients with PRI from July 2004-June 2014 treated at two free-standing children's hospitals and two adult level 1 trauma centers were compared by age (pediatric patients ≤16 years) and PSD. A stratified analysis was performed based on age. The primary outcome was pelvic/presacral abscess. RESULTS: We identified 81 patients with PRI; 19 pediatric, 62 adult. Forty patients had PSD; only three pediatric patients had a drain. Adult patients were more likely to have sustained gunshot wounds (84%), whereas pediatric patients were more likely to sustain impalement injuries (59%). Pediatric patients were more likely to have distal extraperitoneal injuries (56% versus 27% in adults, P = 0.03). PSD was more common in adult patients (59% versus 14%, P = 0.0004), African-Americans (71% versus 11% Caucasian, P < 0.01), and those sustaining gun shot wounds (63% versus 18% impalement, P < 0.01); only race remained significant in stratified analysis for both adult and pediatric patients. There were three cases of pelvic/presacral abscess, all in the adult patients (P = 0.31); one patient with PSD and two without PSD (P = 0.58). In stratified analysis, there were no differences in any infectious complication between those with and without PSD. CONCLUSIONS: Pelvic/presacral abscess is a rare complication of PRI, especially in pediatric patients. PSD is not associated with decreased rates of infectious complications and may not be necessary in the treatment of PRI.

Characterization of fatal blunt injuries using postmortem computed tomography.

BACKGROUND: Rapid triage of blunt agonal trauma patients is necessary to maximize survival, but autopsy is uncommon, slow, and rarely informs resuscitation guidelines. Postmortem computed tomography (PMCT) can serve as an adjunct to autopsy in guiding blunt agonal trauma resuscitation. METHODS: Retrospective cohort review of trauma decedents who died at or within 1 hour of arrival following blunt trauma and underwent noncontrasted PMCT. Primary outcome was the prevalence of mortal injury defined as potential exsanguination (e.g., cavitary injury, long bone and pelvic fractures), traumatic brain injury, and cervical spine injury. Secondary outcomes were potentially mortal injuries (e.g., pneumothorax) and misplacement airway devices. Patients were grouped by whether arrest occurred prehospital/in-hospital. Univariate analysis was used to identify differences in injury patterns including multiple-trauma injury patterns. RESULTS: Over a 9-year period, 80 decedents were included. Average age was 48.9 ± 21.7 years, 68% male, and an average ISS of 42.3 ± 16.3. The most common mechanism was motor vehicle accidents (67.5%) followed by pedestrian struck (15%). Of all decedents, 62 (77.5%) had traumatic arrest prehospital while 18 (22.5%) arrived with pulse. Between groups there were no significant differences in demographics including ISS. The most common mortal injuries were traumatic brain injury (40%), long bone fractures (25%), moderate/large hemoperitoneum (22.5%), and cervical spine injury (25%). Secondary outcomes included moderate/large pneumothorax (18.8%) and esophageal intubation rate of 5%. There were no significant differences in mortal or potentially mortal injuries, and no differences in multiple-trauma injury patterns. CONCLUSION: Fatal blunt injury patterns do not vary between prehospital and in-hospital arrest decedents. High rates of pneumothorax and endotracheal tube misplacement should prompt mandatory chest decompression and confirmation of tube placement in all blunt arrest patients. LEVEL OF EVIDENCE: Prognostic and Epidemiological; Level IV.

Asynchronous Conferencing Through a Secure Messaging Application Increases Reporting of Medical Errors in a Mature Trauma Center.

Background: Medical errors occur frequently, yet they are often under-reported and strategies to increase the reporting of medical errors are lacking. In this work, we detail how a level 1 trauma center used a secure messaging application to track medical errors and enhance its quality improvement initiatives. Methods: We describe the formulation, implementation, evolution, and evaluation of a chatroom integrated into a secure texting system to identify performance improvement and patient safety (PIPS) concerns. For evaluation, we used descriptive statistics to examine PIPS reporting by the reporting method over time, the incidence of mortality and unplanned ICU readmissions tracked in the hospital trauma registry over the same, and time-to-loop closure over the study period to quantify the impact of the processes instituted by the PIPS team. We also categorized themes of reported events. Results: With the implementation of a PIPS chatroom, the number of events reported each month increased and texting became the predominant way for users to report trauma PIPS events. This increase in PIPS reporting did not appear to be accompanied by an increase in mortality and unplanned ICU readmissions. The PIPS team also improved the tracking and timely resolution of PIPS events and observed a decrease in time-to-loop closure with the implementation of the PIPS chatroom. Conclusions: The adoption of clinical texting as a way to report PIPS events was associated with increased reporting of such events and more timely resolution of concerns regarding patient safety and healthcare quality.

Infection after penetrating brain injury-An Eastern Association for the Surgery of Trauma multicenter study oral presentation at the 32nd annual meeting of the Eastern Association for the Surgery of Trauma, January 15-19, 2019, in Austin, Texas.

BACKGROUND: Fatality rates following penetrating traumatic brain injury (pTBI) are extremely high and survivors are often left with significant disability. Infection following pTBI is associated with worse morbidity. The modern rates of central nervous system infections (INF) in civilian survivors are unknown. This study sought to determine the rate of and risk factors for INF following pTBI and to determine the impact of antibiotic prophylaxis. METHODS: Seventeen institutions submitted adult patients with pTBI and survival of more than 72 hours from 2006 to 2016. Patients were stratified by the presence or absence of infection and the use or omission of prophylactic antibiotics. Study was powered at 85% to detect a difference in infection rate of 5%. Primary endpoint was the impact of prophylactic antibiotics on INF. Mantel-Haenszel χ and Wilcoxon's rank-sum tests were used to compare categorical and nonparametric variables. Significance greater than p = 0.2 was included in a logistic regression adjusted for center. RESULTS: Seven hundred sixty-three patients with pTBI were identified over 11 years. 7% (n = 51) of patients developed an INF. Sixty-six percent of INF patients received prophylactic antibiotics. Sixty-two percent of all patients received one dose or greater of prophylactic antibiotics and 50% of patients received extended antibiotics. Degree of dural penetration did not appear to impact the incidence of INF (p = 0.8) nor did trajectory through the oropharynx (p = 0.18). Controlling for other variables, there was no statistically significant difference in INF with the use of prophylactic antibiotics (p = 0.5). Infection was higher in patients with intracerebral pressure monitors (4% vs. 12%; p = <0.001) and in patients with surgical intervention (10% vs. 3%; p < 0.001). CONCLUSION: There is no reduction in INF with prophylactic antibiotics in pTBI. Surgical intervention and invasive intracerebral pressure monitoring appear to be risk factors for INF regardless of prophylactic use. LEVEL OF EVIDENCE: Therapeutic, level IV.

Increased trauma activation is not equally beneficial for all elderly trauma patients.

BACKGROUND: Physiologic changes in the elderly lead to higher morbidity and mortality after injury. Increasing level of trauma activation has been proposed to improve geriatric outcomes, but the increased cost to the patient and stress to the hospital system are significant downsides. The purpose of this study was to identify the age at which an increase in activation status is beneficial. METHODS: A retrospective review of trauma patients 70 years or older from October 1, 2011, to October 1, 2016, was performed. On October 1, 2013, a policy change increased the activation criteria to the highest level for patients 70 years or older with a significant mechanism of injury. Patients who presented prior to (PRE) were compared with those after the change (POST). Data collected included age, Injury Severity Score (ISS), length of stay (LOS), complications, and mortality. Primary outcome was mortality, and secondary outcome was LOS. Multivariable regressions controlled for age, ISS, injury mechanism, and number of complications. RESULTS: A total of 4,341 patients met the inclusion criteria, 1,919 in PRE and 2,422 in POST. Mean age was 80.4 and 81 years in PRE and POST groups, respectively (p = 0.0155). Mean ISS values were 11.6 and 12.4 (p < 0.0001) for the PRE and POST groups. POST had more Level 1 activations (696 vs. 220, p < 0.0001). After controlling for age, ISS, mechanism of injury, and number of complications, mortality was significantly reduced in the POST group 77 years or older (odds ratio, 0.53; 95% confidence interval, 0.3-0.87) (Fig. 1). Hospital LOS was significantly reduced in the POST group age 78 years or older (regression coefficient, -0.55; 95% confidence interval, -1.09 to -0.01) (Fig. 2). CONCLUSIONS: This study suggests geriatric trauma patients 77 years or older benefit from the highest level of trauma activation with shorter LOS and lower mortality. A focused approach to increasing activation level for elderly patients may decrease patient cost. LEVEL OF EVIDENCE: Therapeutic/Care Management, level IV.

The Alvarado score should be used to reduce emergency department length of stay and radiation exposure in select patients with abdominal pain.

BACKGROUND: Abdominal pain is the common reason patients seek treatment in emergency departments (ED), and computed tomography (CT) is frequently used for diagnosis; however, length of stay (LOS) in the ED and risks of radiation remain a concern. The hypothesis of this study was the Alvarado score (AS) could be used to reduce CT scans and decrease ED LOS for patients with suspected acute appendicitis (AA). METHODS: A retrospective review of patients who underwent CT to rule out AA from January 1, 2015, to December 31, 2015, was performed. Patient demographics, medical history, ED documentation, operative interventions, complications, and LOS were all collected. Alvarado score was calculated from the medical record. Time to CT completion was calculated from times the patient was seen by ED staff, CT order, and CT report. RESULTS: Four hundred ninety-two patients (68.1% female; median age, 33 years) met the inclusion criteria. Most CT scans (70%) did not have findings consistent with AA. Median AS for AA on CT scan was 7, compared with 3 for negative CT (p < 0.001). One hundred percent of female patients with AS of 10 and males with AS of 9 or greater had AA confirmed by surgical pathology. Conversely, 5% or less of female patients with AS of 2 or less and 0% of male patients with AS of 1 or less were diagnosed with AA. One hundred six (21.5%) patients had an AS within these ranges and collectively spent 10,239 minutes in the ED from the time of the CT order until the radiologist's report. CONCLUSION: Males with an AS of 9 or greater and females with AS of 10 should be considered for treatment of AA without imaging. Males with AS of 1 or less and females with AS of 2 or less can be safely discharged with follow-up. Using AS, a significant proportion of patients can avoid the radiation risk, the increased cost, and increased ED LOS associated with CT. LEVEL OF EVIDENCE: Diagnostic IV, therapeutic IV.

Laparoscopic removal of a retained intra-abdominal ribbon malleable retractor after 14 years.

We report a case of the laparoscopic removal of a 33 x 5 cm ribbon malleable retractor retained intra-abdominally for 14 years. Plain films revealed a radiopaque object in the midline abdomen consistent with a metallic device. This was a ribbon malleable retractor which was subsequently removed laparoscopically without complication. Laparoscopic surgery should be considered in the removal of foreign bodies from the abdominal cavity.

Improving geriatric trauma outcomes: A small step toward a big problem.

BACKGROUND: Because of the unique physiology and comorbidities of injured geriatric patients, specific interventions are needed to improve outcomes. The purpose of this study was to assess the effect of a change in triage criteria for injured geriatric patients evaluated at an American College of Surgeons Level I trauma center. METHODS: As of October 1, 2013, all injured patients 70 years or older were mandated to have the highest-level trauma activation upon emergency department (ED) arrival regardless of physiology or mechanism of injury. Patients admitted before that date were designated as PRE; those admitted after were designated as POST. The study period was from October 1, 2011, through April 30, 2015. Data collected included demographics, mechanism of injury, hypotension on admission, comorbidities, Injury Severity Score (ISS), ED length of stay (LOS), complications, and mortality. Bivariate and multivariable analyses were used to compare outcomes between the study groups (p < 0.05 was considered significant). χ or Fisher's exact test was used as appropriate for bivariate analyses of categorical variables; patients' ages were compared using the Wilcoxon rank-sum test. RESULTS: A total of 2,269 patients (mean, 80.63 years; mean ISS, 12.2; PRE, 1,271; POST, 933) were included in the study. On multivariable analysis, increasing age, higher ISS, and hypotension were associated with higher mortality. POST patients were more likely to have an ED LOS of 2 hours or shorter (odds ratio, 1.614; 95% confidence interval, 1.088-2.394) after controlling for hypotension, ISS, and comorbidities. POST mortality significantly decreased (odds ratio, 0.689; 95% confidence interval, 0.484-0.979). CONCLUSION: Based on age alone, the focused intervention of a higher level of trauma activation decreased ED LOS and mortality in injured geriatric patients. LEVEL OF EVIDENCE: Therapeutic/care management study, level IV.
