Professionalism of Admitting and Consulting Services and Trauma Patient Outcomes.

OBJECTIVE: To determine whether trauma patients managed by an admitting or consulting service with a high proportion of physicians exhibiting patterns of unprofessional behaviors are at greater risk of complications or death. SUMMARY BACKGROUND DATA: Trauma care requires high-functioning interdisciplinary teams where professionalism, particularly modeling respect and communicating effectively, is essential. METHODS: This retrospective cohort study used data from 9 level I trauma centers that participated in a national trauma registry linked with data from a national database of unsolicited patient complaints. The cohort included trauma patients admitted January 1, 2012 through December 31, 2017. The exposure of interest was care by 1 or more high-risk services, defined as teams with a greater proportion of physicians with high numbers of patient complaints. The study outcome was death or complications within 30 days. RESULTS: Among the 71,046 patients in the cohort, 9553 (13.4%) experienced the primary outcome of complications or death, including 1875 of 16,107 patients (11.6%) with 0 high-risk services, 3788 of 28,085 patients (13.5%) with 1 high-risk service, and 3890 of 26,854 patients (14.5%) with 2+ highrisk services (P < 0.001). In logistic regression models adjusting for relevant patient, injury, and site characteristics, patients who received care from 1 or more high-risk services were at 24.1% (95% confidence interval 17.2% to 31.3%; P < 0.001) greater risk of experiencing the primary study outcome. CONCLUSIONS: Trauma patients who received care from at least 1 service with a high proportion of physicians modeling unprofessional behavior were at an increased risk of death or complications.

Logistics of managing a trauma whole blood inventory in a civilian level 1 trauma center.

BACKGROUND: Institutional data on initiating and maintaining a low-titer O positive whole blood (LTOWB) inventory for the civilian trauma sector may help other institutions start a LTOWB program. This study from a level 1 trauma center with a hospital-based donor center highlights challenges faced during the collection, maintenance, and utilization of LTOWB. STUDY DESIGN AND METHODS: Male O positive donors with low (≤1:100) anti-A and anti-B antibody titers were recruited for LTOWB collection. The daily inventory goal of 4 LTOWB units was kept in the emergency department refrigerator and transfused to adult male trauma patients. Unused units older than 10 days were reprocessed into packed red blood cells. RESULTS: Of 900 donors screened, 61% qualified and 52% of eligible donors provided a collective total of 505 LTOWB units over 2.5 years. The number of collected units directly correlated with the availability of inventory; 42% of the units were transfused, 54% were reprocessed, and 4% were discarded. The inventory goal was maintained for 56% of the year 2018 and 83% of the year 2019. Over these 2 years, 52% of patients had their transfusion needs fully met, 41% had their needs partially met, and 6.5% did not have their needs met. DISCUSSION: Initial challenges to LTOWB implementation were inventory shortages, low utilization rates, and failure to meet clinical demand. Proposed solutions include allowing for a higher yet safe titer, extending shelf life, expanding the donor pool, identifying barriers to utilization, and permitting use in female trauma patients beyond childbearing age.

Effects of the COVID-19 pandemic on pediatric trauma in Southern California.

PURPOSE: The COVID-19 pandemic resulted in increased penetrating trauma and decreased length of stay (LOS) amongst the adult trauma population, findings important for resource allocation. Studies regarding the pediatric trauma population are sparse and mostly single-center. This multicenter study examined pediatric trauma patients, hypothesizing increased penetrating trauma and decreased LOS after the 3/19/2020 stay-at-home (SAH) orders. METHODS: A multicenter retrospective analysis of trauma patients ≤ 17 years old presenting to 11 centers in California was performed. Demographic data, injury characteristics, and outcomes were collected. Patients were divided into three groups based on injury date: 3/19/2019-6/30/2019 (CONTROL), 1/1/2020-3/18/2020 (PRE), 3/19/2020-6/30/2020 (POST). POST was compared to PRE and CONTROL in separate analyses. RESULTS: 1677 patients were identified across all time periods (CONTROL: 631, PRE: 479, POST: 567). POST penetrating trauma rates were not significantly different compared to both PRE (11.3 vs. 9.0%, p = 0.219) and CONTROL (11.3 vs. 8.2%, p = 0.075), respectively. POST had a shorter mean LOS compared to PRE (2.4 vs. 3.3 days, p = 0.002) and CONTROL (2.4 vs. 3.4 days, p = 0.002). POST was also not significantly different than either group regarding intensive care unit (ICU) LOS, ventilator days, and mortality (all p > 0.05). CONCLUSIONS: This multicenter retrospective study demonstrated no difference in penetrating trauma rates among pediatric patients after SAH orders but did identify a shorter LOS.

Drug and alcohol positivity of traumatically injured patients related to COVID-19 stay-at-home orders.

Background: COVID-19 related stay-at-home (SAH) orders created many economic and social stressors, possibly increasing the risk of drug/alcohol abuse in the community and trauma population.Objectives: Describe changes in alcohol/drug use in traumatically injured patients after SAH orders in California and evaluate demographic or injury pattern changes in alcohol or drug-positive patients.Methods: A retrospective analysis of 11 trauma centers in Southern California (1/1/2020-6/30/2020) was performed. Blood alcohol concentration, urine toxicology results, demographics, and injury characteristics were collected. Patients were grouped based on injury date - before SAH (PRE-SAH), immediately after SAH (POST-SAH), and a historical comparison (3/19/2019-6/30/2019) (CONTROL) - and compared in separate analyses. Groups were compared using chi-square tests for categorical variables and Mann-Whitney U tests for continuous variables.Results: 20,448 trauma patients (13,634 male, 6,814 female) were identified across three time-periods. The POST-SAH group had higher rates of any drug (26.2% vs. 21.6% and 24.7%, OR = 1.26 and 1.08, p < .001 and p = .035), amphetamine (10.4% vs. 7.5% and 9.3%, OR = 1.43 and 1.14, p < .001 and p = .023), tetrahydrocannabinol (THC) (13.8% vs. 11.0% and 11.4%, OR = 1.30 and 1.25, p < .001 and p < .001), and 3,4-methylenedioxy methamphetamine (MDMA) (0.8% vs. 0.4% and 0.2%, OR = 2.02 and 4.97, p = .003 and p < .001) positivity compared to PRE-SAH and CONTROL groups. Alcohol concentration and positivity were similar between groups (p > .05).Conclusion: This Southern California multicenter study demonstrated increased amphetamine, MDMA, and THC positivity in trauma patients after SAH, but no difference in alcohol positivity or blood concentration. Drug prevention strategies should continue to be adapted within and outside of hospitals during a pandemic.

Emergency department length of stay in critical nonoperative trauma.

BACKGROUND: Prolonged emergency department (ED) stays correlate with negative outcomes in critically ill nontrauma patients. This study sought to determine the effect of ED length of stay (LOS) on trauma patients. MATERIALS AND METHODS: Two hundred forty-one trauma patients requiring direct intensive care unit (ICU) admission were identified. Patients requiring immediate operative intervention were excluded. Odds ratios (ORs) of outcomes for patients transferred to ICU in ≤90 min were compared with patients transferred in >90 min, adjusting for Injury Severity Score (ISS). RESULTS: One hundred two of 241 patients (42%) were transferred to the ICU in ≤90 min. Increased ED LOS was associated with decreased complications (OR 0.545, 95% confidence interval 0.312-0.952). Although the result was not statistically significant, patients with an ISS >15 were less likely to have long ED stays (OR 0.725, 95% CI 0.407-1.290). No significant difference was seen in mortality. No difference in duration of intubation was observed for patients intubated in the ED versus the ICU. For the subgroup with ISS ≤15, there was a significant decrease in ICU LOS for patients who remained in the ED >90 min (5.5 d versus 2.7 d, P = 0.02). No other differences in LOS were identified. CONCLUSIONS: In a mature trauma center with standardized activation protocols and focused resource allocation in the ED trauma bay, trauma activation and subsequent management appear to mitigate the negative effects of prolonged ED LOS seen in other critically ill populations.

Complications after transcatheter arterial embolization for pelvic trauma: relationship to level and laterality of embolization.

PURPOSE: Transcatheter arterial embolization (TAE) is commonly used to control hemorrhage after pelvic trauma. Despite the procedures reported safety, there can be severe complications, mostly related to ischemia of embolized tissues. Our purpose was to examine the complications of trauma patients resulting from the embolization techniques utilized at our level 1 trauma center. MATERIALS AND METHODS: A retrospective chart review was conducted. One hundred and seven patients who underwent pelvic embolization between January 2003 and December 2013 were included. Patient demographics, ISS, angiography techniques, and major complications including gluteal and skin necrosis, wound breakdown, and deep infection were compared. RESULTS: Nine patients (8.4 %) developed major complications after undergoing TAE. This rate dropped to 5.1 % after exclusion of patients with Morel-Lavallee lesions. Nonselective embolization trended toward a higher complication rate compared to superselective embolization. Patients who developed complications were more likely to have undergone pelvic surgery. CONCLUSION: The majority of patients who developed complications had nonselective TAE. Morel-Lavallee lesions are a confounding factor, but TAE may impose an additional risk. Pelvic surgery after TAE may further predispose patients to complications. We recommend superselective embolization as first-line treatment and caution the use of prophylactic embolization, especially in patients with substantial pelvic soft tissue injuries.

The Effect of 2019 Coronavirus Stay-at-Home Order on Geriatric Trauma Patients in Southern California.

BACKGROUND: California issued stay-at-home (SAH) orders to mitigate COVID-19 spread. Previous studies demonstrated a shift in mechanisms of injuries (MOIs) and decreased length of stay (LOS) for the general trauma population after SAH orders. This study aimed to evaluate the effects of SAH orders on geriatric trauma patients (GTPs), hypothesizing decreased motor vehicle collisions (MVCs) and LOS. METHODS: A post-hoc analysis of GTPs (≥65 years old) from 11 level-I/II trauma centers was performed, stratifying patients into 3 groups: before SAH (1/1/2020-3/18/2020) (PRE), after SAH (3/19/2020-6/30/2020) (POST), and a historical control (3/19/2019-6/30/2019) (CONTROL). Bivariate comparisons were performed. RESULTS: 5486 GTPs were included (PRE-1756; POST-1706; CONTROL-2024). POST had a decreased rate of MVCs (7.6% vs 10.6%, P = .001; vs 11.9%, P < .001) and pedestrian struck (3.4% vs 5.8%, P = .001; vs 5.2%, P = .006) compared with PRE and CONTROL. Other mechanisms of injury, LOS, mortality, and operations performed were similar between cohorts. However, POST had a lower rate of discharge to skilled nursing facility (SNF) (20% vs 24.5%, P = .001; and 20% vs 24.4%, P = .001). CONCLUSION: This retrospective multicenter study demonstrated lower rates of MVCs and pedestrian struck for GTPs, which may be explained by decreased population movement as a result of SAH orders. Contrary to previous studies on the generalized adult population, no differences in other MOIs and LOS were observed after SAH orders. However, there was a lower rate of discharge to SNF, which may be related to a lack of resources due to the COVID-19 pandemic, and thus potentially negatively impacted recovery of GTPs.Keywords.

Effect of protein C gene mutation on coagulation and inflammation in hemorrhagic shock.

INTRODUCTION: Trauma patients are at high risk of complications and death from coagulopathy and inflammatory organ failure. Recent evidence implicates protein C (PC) as a key mediator of this process. We hypothesized that a mutation in the PC gene would ameliorate the inflammatory and coagulopathic response to hemorrhagic shock (HS) and resuscitation. METHODS: FHH wild type and PC mutant rats underwent controlled hemorrhage for 120 min with 70% of blood volume removed. Rats were resuscitated with Ringers lactate (2x shed blood volume) and shed blood. Animals were sacrificed 4 h post-HS. Controls were untreated naïve rats. RESULTS: AST and NFkB lung protein levels were elevated similarly in both WT and mutants compared with naïve rats. Plasma fibrinogen levels decreased significantly with progression of HS compared with baseline (BL) levels and returned towards normal 4 h after resuscitation. PC activity was similar in both groups at BL (0.5 ± 0.08 versus 0.6 ± 0.14; P = 0.14) and decreased from BL by 53% ± 24% in WT (P =0.08), by 67% ± 11% in mutants (P = 0.03) at sacrifice, and was not different between groups (P = 0.29). CONCLUSIONS: Our model of HS and resuscitation produced a hypocoaguable, hyperinflammatory state with increased levels of NFkB and decreased levels of fibrinogen and PC levels. The mutated PC did not appear to alter these responses in our model of HS and resuscitation.

Systematic review and meta-analysis of the 2010 ASGE non-invasive predictors of choledocholithiasis and comparison to the 2019 ASGE predictors.

In 2019, the American Society for Gastrointestinal Endoscopy (ASGE) guideline on the endoscopic management of choledocholithiasis modified the individual predictors of choledocholithiasis proposed in the widely referenced 2010 guideline to improve predictive performance. Nevertheless, the primary literature, especially for the 2019 iteration, is limited. We performed a systematic review with meta-analysis to examine the diagnostic performance of the 2010, and where possible the 2019, predictors. PROSPERO protocol CRD42020194226. A comprehensive literature search from 2001 to 2020 was performed to identify studies on the diagnostic performance of any of the 2010 and 2019 ASGE choledocholithiasis predictors. Identified studies underwent keyword screening, abstract review, and full-text review. The primary outcomes included multivariate odds ratios (ORs) and 95% confidence intervals for each criterion. Secondary outcomes were reported sensitivities, specificities, and positive and negative predictive value. A total of 20 studies met inclusion criteria. Based on reported ORs, of the 2010 guideline "very strong" predictors, ultrasound with stone had the strongest performance. Of the "strong" predictors, CBD > 6 mm demonstrated the strongest performance. "Moderate" predictors had inconsistent and/or weak performance; moreover, all studies reported gallstone pancreatitis as non-predictive of choledocholithiasis. Only one study examined the new predictor (bilirubin > 4 mg/dL and CBD > 6 mm) proposed in the 2019 guideline. Based on this review, aside from CBD stone on ultrasound, there is discordance between the proposed strength of 2010 choledocholithiasis predictors and their published diagnostic performance. The 2019 guideline appears to do away with the weakest 2010 predictors.

Adolescent Trauma During the COVID Pandemic: Just Like Adults, Children, or Someone Else?

COVID-19 stay-at-home (SAH) orders were impactful on adolescence, when social interactions affect development. This has the potential to change adolescent trauma. A post-hoc multicenter retrospective analysis of adolescent (13-17 years-old) trauma patients (ATPs) at 11 trauma centers was performed. Patients were divided into 3 groups based on injury date: historical control (CONTROL:3/19/2019-6/30/2019, before SAH (PRE:1/1/2020-3/18/2020), and after SAH (POST:3/19/2020-6/30/2020). The POST group was compared to both PRE and CONTROL groups in separate analyses. 726 ATPs were identified across the 3 time periods. POST had a similar penetrating trauma rate compared to both PRE (15.8% vs 13.8%, P = .56) and CONTROL (15.8% vs 14.5%, P = .69). POST also had a similar rate of suicide attempts compared to both PRE (1.2% vs 1.5%, P = .83) and CONTROL (1.2% vs 2.1%, P = .43). However, POST had a higher rate of drug positivity compared to CONTROL (28.6% vs 20.6%, P = .032), but was similar in all other comparisons of alcohol and drugs to PRE and POST periods (all P > .05). Hence ATPs were affected differently than adults and children, as they had a similar rate of penetrating trauma, suicide attempts, and alcohol positivity after SAH orders. However, they had increased drug positivity compared to the CONTROL, but not PRE group.

Decreased hospital length of stay and intensive care unit admissions for non-COVID blunt trauma patients during the COVID-19 pandemic.

BACKGROUND: The COVID-19 pandemic overwhelmed hospitals, forcing adjustments including discharging patients earlier and limiting intensive care unit (ICU) utilization. This study aimed to evaluate ICU admissions and length of stay (LOS) for blunt trauma patients (BTPs). METHODS: A retrospective review of COVID (3/19/20-6/30/20) versus pre-COVID (3/19/19-6/30/19) BTPs at eleven trauma centers was performed. Multivariable analysis was used to identify risk factors for ICU admission. RESULTS: 12,744 BTPs were included (6942 pre-COVID vs. 5802 COVID). The COVID cohort had decreased mean LOS (3.9 vs. 4.4 days, p = 0.029), ICU LOS (0.9 vs. 1.1 days, p < 0.001), and rate of ICU admission (22.3% vs. 24.9%, p = 0.001) with no increase in complications or mortality compared to the pre-COVID cohort (all p > 0.05). On multivariable analysis, the COVID period was associated with decreased risk of ICU admission (OR = 0.82, CI 0.75-0.90, p < 0.001). CONCLUSIONS: BTPs had decreased LOS and associated risk of ICU admission during COVID, with no corresponding increase in complications or mortality.

Selective use of computed tomography compared with routine whole body imaging in patients with blunt trauma.

STUDY OBJECTIVE: Routine pan-computed tomography (CT, including of the head, neck, chest, abdomen/pelvis) has been advocated for evaluation of patients with blunt trauma based on the belief that early detection of clinically occult injuries will improve outcomes. We sought to determine whether selective imaging could decrease scan use without missing clinically important injuries. METHODS: This was a prospective observational study of 701 patients with blunt trauma at an academic trauma center. Before scanning, the most senior emergency physician and trauma surgeon independently indicated which components of pan-CT were necessary. We calculated the proportion of scans deemed unnecessary that: (a) were abnormal and resulted in a pre-defined critical action or (b) were abnormal. RESULTS: Pan-CT was performed in 600 of the patients; the remaining 101 underwent limited scanning. One or both physicians indicated a willingness to omit 35% of the individual scans. An abnormality was present in 18% of scans, including 22% of desired scans and 10% of undesired scans. Among the 95 patients who had one of the 102 undesired scans with abnormal results, 3 underwent a predefined critical action. There is disagreement among the authors about the clinical significance of the abnormalities found on the 99 undesired scans that did not lead to a critical action. CONCLUSION: Selective scanning could reduce the number of scans, missing some injuries but few critical ones. The clinical importance of injuries missed on undesired scans was subject to individual interpretation, which varied substantially among authors. This difference of opinion serves as a microcosm of the larger debate on appropriate use of expensive medical technologies.

A pilot study of stored low titer group O whole blood + component therapy versus component therapy only for civilian trauma patients.

BACKGROUND: This pilot assessed transfusion requirements during resuscitation with whole blood followed by standard component therapy (CT) versus CT alone, during a change in practice at a large urban Level I trauma center. METHODS: This was a single-center prospective cohort pilot study. Male trauma patients received up to 4 units of cold-stored low anti-A, anti-B group O whole blood (LTOWB) as initial resuscitation followed by CT as needed (LTOWB + CT). A control group consisting of women and men who presented when LTOWB was unavailable, received CT only (CT group). Exclusion criteria included antiplatelet or anticoagulant medication and death within 24 hours. The primary outcome was total transfusion volume at 24 hours. Secondary outcomes were mortality, morbidity, and intensive care unit- and hospital-free days. RESULTS: Thirty-eight patients received LTOWB, with a median of 2.0 (interquartile range [IQR] 1.0-3.0) units of LTOWB transfused. Thirty-two patients received CT only. At 24 hours after presentation, the LTOWB +CT group had received a median of 2,138 mL (IQR, 1,275-3,325 mL) of all blood products. The median for the CT group was 4,225 mL (IQR, 1,900-5,425 mL; p = 0.06) in unadjusted analysis. When adjusted for Injury Severity Score, sex, and positive Focused Assessment with Sonography for Trauma, LTOWB +CT group patients received 3307 mL of blood products, and CT group patients received 3,260 mL in the first 24 hours (p = 0.95). The adjusted median ratio of plasma to red cells transfused was higher in the LTOWB + CT group (0.85 vs. 0.63 at 24 hours after admission; p = 0.043. Adjusted mortality was 4.4% in the LTOWB + CT group, and 11.7% in the CT group (p = 0.19), with similar complications, intensive care unit-, and hospital-free days in both groups. CONCLUSION: Beginning resuscitation with LTOWB results in equivalent outcomes compared with resuscitation with CT only. LEVEL OF EVIDENCE: Therapeutic (Prospective study with 1 negative criterion, limited control of confounding factors), level III.

Changes in traumatic mechanisms of injury in Southern California related to COVID-19: Penetrating trauma as a second pandemic.

BACKGROUND: The COVID-19 pandemic resulted in a statewide stay-at-home (SAH) order in California beginning March 19, 2020, forcing large-scale behavioral changes and taking an emotional and economic toll. The effects of SAH orders on the trauma population remain unknown. We hypothesized an increase in rates of penetrating trauma, gunshot wounds, suicide attempts, and domestic violence in the Southern California trauma population after the SAH order. METHODS: A multicenter retrospective analysis of all trauma patients presenting to 11 American College of Surgeons levels I and II trauma centers spanning seven counties in California was performed. Demographic data, injury characteristics, clinical data, and outcomes were collected. Patients were divided into three groups based on injury date: before SAH from January 1, 2020, to March 18, 2020 (PRE), after SAH from March 19, 2020, to June 30, 2020 (POST), and a historical control from March 19, 2019, to June 30, 2019 (CONTROL). POST was compared with both PRE and CONTROL in two separate analyses. RESULTS: Across all periods, 20,448 trauma patients were identified (CONTROL, 7,707; PRE, 6,022; POST, 6,719). POST had a significantly increased rate of penetrating trauma (13.0% vs. 10.3%, p < 0.001 and 13.0% vs. 9.9%, p < 0.001) and gunshot wounds (4.5% vs. 2.4%, p = 0.002 and 4.5% vs. 3.7%, p = 0.025) compared with PRE and CONTROL, respectively. POST had a suicide attempt rate of 1.9% and a domestic violence rate of 0.7%, which were similar to PRE (p = 0.478, p = 0.514) and CONTROL (p = 0.160, p = 0.618). CONCLUSION: This multicenter Southern California study demonstrated an increased rate of penetrating trauma and gunshot wounds after the COVID-19 SAH orders but no difference in attempted suicide or domestic violence rates. These findings may provide useful information regarding resource utilization and a target for societal intervention during the current or future pandemic(s). LEVEL OF EVIDENCE: Epidemiological, level IV.

COVID-19 in trauma: a propensity-matched analysis of COVID and non-COVID trauma patients.

PURPOSE: There is mounting evidence that surgical patients with COVID-19 have higher morbidity and mortality than patients without COVID-19. Infection is prevalent amongst the trauma population, but any effect of COVID-19 on trauma patients is unknown. We aimed to evaluate the effect of COVID-19 on a trauma population, hypothesizing increased mortality and pulmonary complications for COVID-19-positive (COVID) trauma patients compared to propensity-matched COVID-19-negative (non-COVID) patients. METHODS: A retrospective analysis of trauma patients presenting to 11 Level-I and II trauma centers in California between 1/1/2019-6/30/2019 and 1/1/2020-6/30/2020 was performed. A 1:2 propensity score model was used to match COVID to non-COVID trauma patients using age, blunt/penetrating mechanism, injury severity score, Glasgow Coma Scale score, systolic blood pressure, respiratory rate, and heart rate. Outcomes were compared between the two groups. RESULTS: A total of 20,448 trauma patients were identified during the study period. 53 COVID trauma patients were matched with 106 non-COVID trauma patients. COVID patients had higher rates of mortality (9.4% vs 1.9%, p = 0.029) and pneumonia (7.5% vs. 0.0%, p = 0.011), as well as a longer mean length of stay (LOS) (7.47 vs 3.28 days, p < 0.001) and intensive care unit LOS (1.40 vs 0.80 days, p = 0.008), compared to non-COVID patients. CONCLUSION: This multicenter retrospective study found increased rates of mortality and pneumonia, as well as a longer LOS, for COVID trauma patients compared to a propensity-matched cohort of non-COVID patients. Further studies are warranted to validate these findings and to elucidate the underlying pathways responsible for higher mortality in COVID trauma patients.

The coronavirus disease 2019 (COVID-19) stay-at-home order's unequal effects on trauma volume by insurance status in Southern California.

BACKGROUND: The rapid spread of coronavirus disease 2019 in the United States led to a variety of mandates intended to decrease population movement and "flatten the curve." However, there is evidence some are not able to stay-at-home due to certain disadvantages, thus remaining exposed to both coronavirus disease 2019 and trauma. We therefore sought to identify any unequal effects of the California stay-at-home orders between races and insurance statuses in a multicenter study utilizing trauma volume data. METHODS: A posthoc multicenter retrospective analysis of trauma patients presenting to 11 centers in Southern California between the dates of January 1, 2020, and June 30, 2020, and January 1, 2019, and June 30, 2019, was performed. The number of trauma patients of each race/insurance status was tabulated per day. We then calculated the changes in trauma volume related to stay-at-home orders for each race/insurance status and compared the magnitude of these changes using statistical resampling. RESULTS: Compared to baseline, there was a 40.1% drop in total trauma volume, which occurred 20 days after stay-at-home orders. During stay-at-home orders, the average daily trauma volume of patients with Medicaid increased by 13.7 ± 5.3%, whereas the volume of those with Medicare, private insurance, and no insurance decreased. The average daily trauma volume decreased for White, Black, Asian, and Latino patients with the volume of Black and Latino patients dropping to a similar degree compared to White patients. CONCLUSION: This retrospective multicenter study demonstrated that patients with Medicaid had a paradoxical increase in trauma volume during stay-at-home orders, suggesting that the most impoverished groups remain disproportionately exposed to trauma during a pandemic, further exacerbating existing health disparities.

Disparity in management and long-term outcomes of pediatric splenic injury in California.

OBJECTIVE: To determine the impact of evidence-based guidelines on the disparities in management of pediatric splenic injuries (PSI). SUMMARY OF BACKGROUND DATA: Several studies have highlighted a disparity in the utilization of nonoperative management (NOM) for PSI based on hospital and surgeon characteristics. Whether evidence-based guidelines had an impact on mitigating this disparity is uncertain. METHODS: From 1999 to 2006, children < or = 18 years with PSI were extracted from California's Patient Discharge Database (n = 5089). Patient demographics, injury grade, immediate and delayed operations, readmissions, and complications were analyzed. RESULTS: The overall rates of immediate operative management (IOM) decreased significantly from 23% in 1999 to 15% in 2006 (P < 0.001). This decline was attributed entirely to reduction of IOM at non-children's hospitals (NCH) (29% to 20%, P < 0.001). In contrast, IOM rates were low and unchanged at children's hospital (CH) (9%, P = NS). Failed NOM (3.3%), readmissions for complications (0.6%), and operations (0.3%) were rare and unaffected by NOM increase. NCH had increased risk of IOM compared to CH in multivariate analysis (OR: 2.00, 99% CI: 1.09-3.57). The rate of delayed splenic rupture was 0.2%. There were no differences when comparing the rates of readmissions (1.0% vs. 0.4%, P = NS) and readmit operations (0.3% vs. 0.3%, P = NS) between IOM versus NOM. CONCLUSION: A steady increase in the utilization of NOM for PSI in California over time was attributed entirely to changing practices at NCH. Increasing NOM has occurred without a concurrent increase in complications. Delayed splenic ruptures were rare. Although IOM rates at NCH decreased over time, disparity in NOM utilization still exists between NCH and CH.

Functional status after injury: a longitudinal study of geriatric trauma.

We evaluated self-rated functional status measured longitudinally in the year after injury in a geriatric trauma population. The longitudinal (L) group included 37 of 60 eligible trauma patients aged 65 years or older admitted December 2006 to November 2007 for greater than 24 hours who completed a Short Functional Status questionnaire (SFS) at 3, 6, and 12 months after injury. The SFS yields scores of 0 to 5 (5 = independent in all five activities of daily living [ADLs]) and has been validated among community-dwelling elders. The control (C) group included 63 trauma patients aged 65 years or older admitted December 2007 to July 2009 for greater than 24 hours who reported their preinjury functional status using the SFS at hospital admission. We used characteristics and scores of the C group to impute preinjury ADL scores for the L group. The groups were similar in baseline characteristics (age, ethnicity, Injury Severity Score, Charlson Comorbidity Index, and living arrangement; P > 0.05). For the C group, the preinjury ADL score was 4.6 (SD = 0.9). For the L group, ADL scores declined at all intervals reaching statistical significance at 12 months. We conclude that in the year after traumatic injury, geriatric patients lost the equivalent of approximately one ADL, increasing their risk of further functional decline, loss of independence, and death.

Quality of Care Within a Trauma Center Is not Altered by Injury Type.

BACKGROUND: : Previous studies have demonstrated variations in severity-adjusted mortality between trauma centers. However, it is not clear if outcomes vary by the type of injury being treated. METHODS: : National Trauma Data Bank was used to identify patients 16 years or older with moderate to severe injuries (Abbreviated Injury score > or =3) treated at level I or II trauma centers (n = 127,439 patients, 105 centers). Observed-to-Expected mortality ratios (O/E ratios, 95% confidence interval [CI]) were calculated for each trauma center within each of the three injury types: blunt multisystem (two or more body regions; n = 27,980; crude mortality, 15%), penetrating torso (neck, chest, or abdomen; n = 9,486; crude mortality, 9%), and blunt single system (n = 89,973; crude mortality 5%). Multivariate logistic regression was used to adjust for age, gender, mechanism, transfer status, and injury severity (Glasgow Coma Scale, blood pressure). For each injury type, trauma centers' performance was ranked as high (O/E with 95% CI <1), low (O/E with 95% CI >1), or average performers (O/E overlapping 1). RESULTS: : Almost three quarters of the trauma centers achieved the same performance rank in each of the three injury categories. There were 14 low-performing trauma centers in blunt multisystem injuries, six in penetrating torso injuries, and nine in the blunt single system injuries group. None of these centers achieved high performance in any other type of injury. CONCLUSIONS: : Risk-adjusted outcomes are consistent within trauma centers across different types of injuries, suggesting that quality improvement efforts should measure, analyze, and focus on hospital-wide systems of care, rather than on isolated quality domains related to specific types of injury.

Hips can lie: impact of excluding isolated hip fractures on external benchmarking of trauma center performance.

BACKGROUND: Trauma centers (TCs) vary in the inclusion of patients with isolated hip fractures (IHFs) in their registries. This inconsistent case ascertainment may have significant implications on the assessment of TC performance and external benchmarking efforts. METHODS: Data were derived from the National Trauma Data Bank (2007-8.1). We included patients (aged 16 years or older) with Injury Severity Score value ≥ 9 who were admitted to Level I and II TCs. To ensure data quality, we limited the study to TC that routinely reported comorbidities and Abbreviated Injury Scale codes. IHF were defined as patients, aged 65 years or older, injured as a result of falls, with Abbreviated Injury Scale codes for hip fracture and without other significant injuries. TCs were stratified according to their reported inclusion of IHF in their registry. Observed-to-expected mortality ratios were used to rank TC performance first with and then, without the inclusion of patients with IHF. RESULTS: In total, 91,152 patients in 132 TCs were identified; 5% (n = 4,448) were IHF. The proportion of IHF per TC varied significantly, ranging from 0% to 31%. When risk-adjusted mortality was evaluated, excluding patients with IHF had significant effects: 37% (n = 49) of TCs changed their performance rank by ≥ 3 (range, 1-25) and 12% of centers changed their performance quintile. The greatest change in rank performance was evident in centers that routinely include IHF in their registries. CONCLUSIONS: Given the fact that IHFs in the elderly significantly influence risk-adjusted outcomes and are variably reported by TCs, these patients should be excluded from subsequent benchmarking efforts.
