Trauma centers face novel challenges in resource allocation in an era of cost consciousness and work-hour restrictions. Studies have shown that time of day and day of week affect trauma admission volume; however, these studies were performed in cold climates. Data from 2000 to 2010 at a Level I trauma center were reviewed. Demographic, injury severity, and injury timing from 23,827 trauma patients were analyzed along with their emergency department disposition (operating room, intensive care unit, ward) and final outcome. Nighttime arrivals (NAs) accounted for 56.6 per cent and daytime arrivals accounted for 43.4 per cent of total admissions. The increase in NAs was most pronounced during the period from midnight to 6 AM on weekends ( P < 0.05). Also, the period from midnight to 6 AM on weekends showed a significantly increased proportion of penetrating trauma ( P < 0.01). Similarly, there was an increased rate of trauma arrivals needing emergent operative intervention in the period between midnight and 6 AM on weekends when compared with any other time period ( P < 0.01). In a southern Level I trauma center, patient volume varies nonrandomly with time. Emergent operative intervention is more likely between midnight and 6 AM, the peak time for penetrating trauma. Because resident operative experience is maximized at night and on weekends, coverage during these periods should remain a priority for residency programs.

The ACS Committee on Trauma specifies prehospital criteria that trigger trauma team activation (TTA). The study aims to define the relationship between TTA and time of day, mechanism of injury, and need for operative intervention. All trauma patients presenting to LAC1USC (January 2008–July 2018) after triggering TTA were screened. Patients were excluded if time of ED arrival was undocumented. Demographics, injury data, and outcomes were analyzed. After exclusions (<1%), 54,826 patients were enrolled. The median age was 35 [IQR 23–53]. The median Injury Severity Score was 4 [1–10]. The most common mechanisms of injury were falls (n = 14,166; 31%), auto versus pedestrian collisions (n = 11,921; 26%), and motor vehicle collisions (n = 11,024; 24%). Penetrating trauma comprised 16 per cent (n = 8,686). The busiest hour for TTAs was 19:00 to 20:00, although penetrating trauma was most common between 23:00 and 01:00. Emergent surgical intervention in absolute numbers was most frequent between 20:00 and 01:00. As a proportion of the number of TTAs per hour, emergent operative intervention was most frequent between 23:00 and 06:00. In conclusion, the volume of TTAs and the triggering mechanism of injury vary significantly by time of day. The need for operative intervention is highest overnight. This information can be used to help increase hospital preparedness and allocate resources accordingly.

Background Changes in injury patterns during the COVID pandemic have been reported in other states. The objective was to explore changes to trauma service volume and admission characteristics at a trauma center in northeast Ohio during a stay-at-home order (SAHO) and compare the 2020 data to historic trauma census data. Methods Retrospective chart review of adult trauma patients admitted to a level I trauma center in northeast Ohio. Trauma admissions from January 21 to July 21, 2020 (COVID period) were compared to date-matched cohorts of trauma admissions from 2018 to 2019 (historic period). The COVID period was further categorized as pre-SAHO, active-SAHO, and post-SAHO. Results The SAHO was associated with a reduction in trauma center admissions that increased after the SAHO ( P = .0033). Only outdoor recreational vehicle (ORV) injuries ( P = .0221) and self-inflicted hanging ( P = .0028) mechanisms were increased during the COVID period and had substantial effect sizes. Glasgow Coma Scores were lower during the COVID period ( P = .0286) with a negligible effect size. Violence-related injuries, injury severity, mortality, and admission characteristics including alcohol and drug testing and positivity were similar in the COVID and historic periods. Discussion The SAHO resulted in a temporary decrease in trauma center admissions. Although ORV and hanging mechanisms were increased, other mechanisms such as alcohol and toxicology proportions, injury severity, length of stay, and mortality were unchanged.

The objective of this study was to analyze the transfusion practices in trauma patients in one institution. A retrospective analysis of the Trauma Registry linked with the Blood Bank Database of a Level 1 trauma center was conducted. Over 6 years, 17 per cent of the 25,599 trauma patients received blood transfusions. The overall mortality in transfused patients was 20 per cent and remained the same during the study period. There was no change in the proportion of patients receiving transfusions throughout the years, however there was a significant 23.5 per cent reduction in the mean number of packed red blood cells (PRBC) units transfused (P < 0.001 for trend). This reduction in PRBC used remained true and even more evident in the group of more severely injured patients (Injury Severity Score ≥ 16), with a 27.9 per cent decrease in mean units of PRBC (P < 0.001 for trend). The highest reduction in PRBC transfusion was seen in blunt trauma patients (34.6%, P < 0.001). During the study period there was a concurrent increase in mean units of fresh frozen plasma used (60.7%, P < 0.001) and no change in the use of platelets and cryoprecipitate. In conclusion, transfusions of PRBC were significantly reduced over time in trauma patients without any evident negative impact on mortality.

Introduction An American College of Surgeons (ACS) Level-I (L-I) pediatric trauma center demonstrated successful laparoscopy without conversion to laparotomy in ∼65% of trauma cases. Prior reports have demonstrated differences in outcomes based on ACS level of trauma center. We sought to compare laparoscopy use for blunt abdominal trauma at L-I compared to Level-II (L-II) centers. Methods The Pediatric Trauma Quality Improvement Program was queried (2014-2016) for patients ≤16 years old who underwent any abdominal surgery. Bivariate analyses comparing patients undergoing abdominal surgery at ACS L-I and L-II centers were performed. Results 970 patients underwent abdominal surgery with 14% using laparoscopy. Level-I centers had an increased rate of laparoscopy (15.6% vs 9.7%, P = .019 ); however they had a lower mean Injury Severity Score (16.2 vs 18.5, P = .002) compared to L-II centers. Level-I and L-II centers had similar length of stay ventilator days, and SSIs (all P > .05). Conclusion While use of laparoscopy for pediatric trauma remains low, there was increased use at L-I compared to L-II centers with no difference in LOS or SSIs. Future studies are needed to elucidate which pediatric trauma patients benefit from laparoscopic surgery.

With a considerably increasing elderly population, we sought to determine whether the volume of elderly trauma patients treated impacted outcomes at two different Level I trauma centers. This is a retrospective review of all elderly patients (>60 years) at two state-verified Level I trauma centers over the past five years. The elderly trauma center (ETC) saw a greater proportion (52%) of elderly patients than the reference trauma center (30%, TC). Demographic and clinical characteristics were abstracted and stratified into ETC and TC groups for comparison. Primary outcomes were overall postinjury complication and mortality rates, as well as death after major complication (failure to rescue). ETC patients were older (78.6 vs 70.5), more likely to be admitted with severe head injuries (head abbreviated injury score ≥ 3, 50.0% vs 32%), had a greater overall injury burden (injury severity score > 16 41.4% vs 21.1%), and required intensive care unit admission (81.3% vs 64%) than the TC group. Need for operative intervention, mechanism of injury, and comorbidities were similar between the two groups. Overall complications were higher in trauma patients admitted to the TC (21.9% vs 14.3%), as well as failure to rescue (4.0% vs 1.8%). Adjusting for confounding factors, ETC had significantly lower chance of developing a postinjury complication (adjusted odds ratios [AOR] = 0.4, 95% confidence interval [CI] = [0.3, 0.5]), failure to rescue (AOR = 0.3, 95% CI = [0.1, 0.5]), and overall mortality (AOR = 0.3, 95% CI = [0.2, 0.4]). Improved outcomes were demonstrated in the Level I center treating a higher proportion of elderly patients. Exact etiology of these benefits should be determined for quality improvement in care of the injured geriatric patient.

To determine whether a positive blood alcohol level (BAL) affects morbidity and mortality at a Level I trauma center, a retrospective review of trauma patients 18 years of age and older was performed. There were 7985 trauma patients and 8 per cent (645) had a positive BAL. BAL(+) patients had lower Injury Severity Score (ISS) (8 vs 11, P < 0.01), lower rate of penetrating injury (9 vs 25%, P < 0.01), and were older (38 vs 32 years, P = 0.01). Overall there were 559 deaths (7%); (1% mortality in BAL(+) patients and 7% in BAL(-) patients; P < 0.0001). There were 352 (4.4%) complications with similar rates among BAL(-) and (+) patients. On univariate analysis, a positive BAL was inversely associated with death (OR, 0.17) as was blunt trauma (OR, 0.29), whereas older age (OR 1.009) and increased ISS (OR 1.13) were associated with death. On multivariable analysis, after adjusting for age, ISS, and mechanism of injury, a positive BAL remained protective against death (OR 0.35) as did blunt trauma (OR 0.2). Age (OR 1.04) and increased ISS (OR 1.19) were associated with mortality. In conclusion, a positive BAL was associated with a decreased mortality risk in trauma patients, which persisted after adjusting for multiple confounding variables.

The Impact

Trauma centers are designated by the American College of Surgeons (ACS) into four different levels based on resources, volume, and scientific and educational commitment. The purpose of this study was to evaluate the relationship between ACS center designation and outcomes after early thoracotomy for trauma. The National Trauma Databank (v. 7.0) was used to identify all patients who required early thoracotomy. Demographics, clinical data, and outcomes were extracted. Patients were categorized according to ACS trauma center designation. Multivariate logistic regression was used to evaluate the impact of ACS trauma center designation on mortality. From 2002 to 2006, 1834 (77.4%) patients were admitted to a Level I ACS verified trauma center, 474 (20.0%) to a Level II, and 59 (3.6%) to a Level III/IV facility. After adjusting for differences between the groups, there were no significant differences in mortality (overall: 53.3% for Level I, 63.1% for Level II, and 52.5% for Level III/IV, adjusted P = 0.417; or for patients arriving in cardiac arrest: 74.9% vs 87.1% vs 85.0%, P = 0.261). Subgroup analysis did not show any significant difference in survival irrespective of mechanism of injury. Glasgow Coma Scale score # 8, Injury Severity Score >16, no admission systolic blood pressure, time from admission to thoracotomy, and nonteaching hospitals were found to be independent predictors of death. For trauma patients who have sustained injuries requiring early thoracotomy, ACS trauma center designation did not significantly impact mortality. Nonteaching institutions however, were independently associated with poorer outcomes after early thoracotomy. These findings may have important implications in educational commitment of institutions. Further prospective evaluation of these findings is warranted.

Purpose: Prehospital triage criteria (PTC) have been used to classify patients according to risk of serious injury. This study was conducted determine whether PTC could be used to identify serious injury, the need for intensive care (ICU), or immediate operative intervention (IOI).Methods: Data for this observational study were gathered prospectively, at a level-I trauma center, from a patient cohort admitted to the trauma service from 01 February to 31 July 1995. Specific triage criteria, based on information given by EMS prior to arrival were used to categorize patients by severity. Patients classified as most serious (codes) had the following: shock, major anatomic injury or proximal penetrating trauma. Patients classified as more serious (alerts) had one of the following: abnormal vital signs, Glasgow Coma Scale <13, moderate anatomic injury, high-risk mechanism of injury, or co-morbid factors. Patients not meeting either set of criteria, but were admitted, served as controls (consults). Injury severity scores (ISS) and probability of survival (Probsurvival) were calculated for each patient. The percentage admitted to the ICU, operating room (OR), or requiring IOI, were tabulated. Statistical analysis was performed using ANOVA, Mest and chi-square.

AbstractBackground:The increase in mortality and total prehospital time (TPT) seen in Qatar appear to be realistic. However, existing reports on the influence of TPT on mortality in trauma patients are conflicting. This study aimed to explore the impact of prehospital time on the in-hospital outcomes.Methods:A retrospective analysis of data on patients transferred alive by Emergency Medical Services (EMS) and admitted to Hamad Trauma Center (HTC) of Hamad General Hospital (HGH; Doha, Qatar) from June 2017 through May 2018 was conducted. This study was centered on the National Trauma Registry database. Patients were categorized based on the trauma triage activation and prehospital intervals, and comparative analysis was performed.Results:A total of 1,455 patients were included, of which nearly one-quarter of patients required urgent and life-saving care at a trauma center (T1 activations). The overall TPT was 70 minutes and the on-scene time (OST) was 24 minutes. When compared to T2 activations, T1 patients were more likely to have been involved in road traffic injuries (RTIs); experienced head and chest injuries; presented with higher Injury Severity Score (ISS: median = 22); and had prolonged OST (27 minutes) and reduced TPT (65 minutes; P = .001). Prolonged OST was found to be associated with higher mortality in T1 patients, whereas TPT was not associated.Conclusions:In-hospital mortality was independent of TPT but associated with longer OST in severely injured patients. The survival benefit may extend beyond the golden hour and may depend on the injury characteristics, prehospital, and in-hospital settings.

In the 80-hour work week era, optimal distribution of the residency workforce is critical. Little data exist as to whether current hours of hospital staffing parallel trends in trauma activity. The purpose of this study was to determine peak periods of trauma volume, severity, need for operative intervention, and mortality and determine if there are differences in mortality based on time period of arrival. We performed a retrospective analysis of the 17,167 patients admitted to our academic Level I trauma center between 2000 and 2007. Each admission was plotted against time of arrival and trends noted. A significant increase in activity occurred between 1700 and 0100 hours. Compared with other shifts, this shift had a disproportionately higher number of patients with penetrating injuries, need for operative intervention, Injury Severity Score (ISS) greater than 15, and death ( P < 0.0001). After adjusting for ISS and penetrating trauma, arrival time was not predictive of mortality (OR 0.97, CI 0.87-1.08, P = 0.6). In conclusion, a peak in trauma activity occurs during an evening shift between 1700 and 0100 hours. In an era of optimizing resident training within the constraints of an 80-hour work week, strong consideration should be made for deploying personnel to match these findings.
