SARS-Co-V-2 positive status is associated with a more seriously injured population of trauma patients but not independently associated with worse outcomes of trauma care.

BACKGROUND: SARS-CoV-2 positive status has been considered a predominantly incidental finding among trauma patients. We sought to examine whether concurrent infection is associated with worse outcomes in a contemporary cohort of injured patients during the COVID-19 pandemic. METHODS: Retrospective cohort analysis of a level I trauma center's institutional registry from May 1, 2020 through June 30, 2021. The prevalence of COVID in the trauma population was compared monthly using prevalence ratios relative to population estimates. Unadjusted cohorts of COVID+ vs COVID- trauma patients were compared. COVID+ patients then were matched on age, mechanism of injury, year, and injury severity score (ISS) with COVID- controls for adjusted analysis with a primary composite outcome of mortality. RESULTS: Out of n=2,783 trauma activations, n=51 (1.8%) were COVID+. Compared to the general population, the trauma population had prevalence ratios for COVID of 5.3 to 79.7 (median=20.8). Compared to COVID- patients, COVID+ patients had worse outcomes, including a higher proportion who were admitted to the ICU, required intubation, underwent a major operation, and had greater total charges and a longer length of stay. However, these differences appeared related to more severe injury patterns in the COVID+ cohort. In the adjusted analysis, no significant differences between groups in any of the outcome variables were observed. CONCLUSIONS: Worse trauma outcomes in COVID+ patients appear to be correlated to the more substantial patterns of injury observed in this group. Trauma patients have substantially higher rates of SARS-CoV-2 positivity than the local population at large. These results reinforce that this population is vulnerable to multiple threats. They will guide the ongoing delivery of care in shaping the needs for testing, PPE for those delivering care, and the capacity and operational needs of trauma systems that must care for a population with such high rates of SARS-CoV-2 infection.

National patterns of injury and outcomes of gunshot wounds to the penis: A Trauma Quality Programs retrospective cohort analysis.

AIM: Gunshot wounds (GSW) to the penis represent a rare type of traumatic injury in the civilian United States population. Although small, single-center studies have reported results of care for these types of injured patients, no national analyses have examined this group. METHODS: A cohort of patients with GSW to the penis was identified using the 2017 American College of Surgeons Trauma Quality Programs database, a comprehensive national database of 753 accredited trauma centers. RESULTS: Gunshot wounds to the penis occurred in 722 patients, which represents 1.7% of all GSW patients (n = 41,017). Gunshot wounds from altercations with law enforcement or accidental discharge of a firearm were rare; the vast majority (n = 655, 90.7%) occurred as a result of assault, intentional self-harm, attempted suicide, or attempted homicide. Patients with a major concomitant non-genitourinary injury comprised 119 (16.5%) patients of the cohort. Most patients (n = 499, 69.1%) underwent a genitourinary procedure during their trauma admission. Penile salvage was successful in most cases, with only 13 (1.8%) patients requiring completion penectomy. Most patients (87.8%) required admission with a median length of stay of 49.8 h. Most patients were treated at the initial trauma center without requiring transfer to another center, and complications during admission were rare. CONCLUSIONS: This analysis, the first national examination of care of patients with GSW to the penis, reveals overall favorable outcomes. Admission and surgical intervention were required in most patients, but penectomy was rare and length of stay was generally short. These results will guide resource utilization and quality improvement efforts in this patient cohort.

Kids grow up so fast: national patterns of positive drug/alcohol screens among pediatric trauma patients.

BACKGROUND: National guidelines recommend screening all trauma patients for drug and alcohol use beginning at age 12, but no national data have examined rates of screening or positive results in this population. METHODS: We examined national testing rates and results among all trauma patients under 21 years old in the 2017 American College of Surgeons Trauma Quality Programs (TQP) database. RESULTS: Of a cohort of n = 157,450 pediatric and adolescent trauma patients, n = 45,443 (28.9%) were screened, and n = 16,662 (36.7%) of those had a positive result. While both testing and positive results increased with age, testing rates were only 61.7% by age 20 and the prevalence of positive results was significant even at younger ages. Cannabinoids were the most commonly detected substance, followed by alcohol, and then opioids. CONCLUSIONS: These national data support the need for further efforts to increase screening rates and provide structured interventions to mitigate the consequences of substance abuse. IMPACT: These data provide the first national evidence of underutilization of drug and alcohol screening in pediatric and adolescent trauma patients, with substantial rates of positive screens among those tested. Cannabinoids were the most commonly detected substance, followed by alcohol and then opioids. These data should guide physicians' and policymakers' efforts to improve screening in this high-risk population, which will amplify the potential benefits of using the trauma admission as a critical opportunity to intervene with structured programs to mitigate the consequences of substance abuse.

Pregnant trauma patients may be at increased risk of mortality compared to nonpregnant women of reproductive age: trends and outcomes over 10 years at a level I trauma center.

BACKGROUND: Pregnancy has been identified as a risk factor for poor outcomes after traumatic injury, but prior outcome analyses are conflicting and dated. We sought to examine outcomes in a contemporary cohort. METHODS: Retrospective cohort analysis at a level I trauma center's institutional registry from 2009 to 2018, with comparison to population-level demographic trends in women of reproductive age and pregnancy prevalence. Unadjusted cohorts of pregnant versus nonpregnant trauma patients were compared. Pregnant patients then were matched on age, mechanism of injury, year, and injury severity score with nonpregnant controls for adjusted analysis with a primary outcome of maternal mortality. RESULTS: Despite declining birth and pregnancy rates in the population, pregnant women comprised a stable 5.3% of female trauma patients of reproductive age without decline over the study period (p = 0.53). Compared with nonpregnant women, pregnant trauma patients had a lower injury severity score (1 [1-5] vs 5 [1-10] p < 0.0001) and a shorter length of stay (1 [1-2] vs 1 [1-4] p = 0.04), were less likely to have CT imaging (48.8% vs 67.4%, p < 0.0001) and more likely to be admitted (89.3% vs 79.2%, p = 0.003). Positive toxicology screens were less prevalent in pregnant women, but only for ethanol (5.4% vs 31.4%, p < 0.0001); there was no difference in rates of cannabis, opiates, or cocaine. After matching to adjust for age, year, mechanism of injury, and injury severity score, mortality occurred significantly more frequently in the pregnant cohort (2.1% vs 0.2%, OR = 13.5 [1.39-130.9], p = 0.02). CONCLUSION: Pregnant trauma patients have not declined in our population despite population-level declines in pregnancy. After adjusting for lower injury severity, pregnant women were at substantially greater risk of mortality. This supports ongoing concern for pregnant trauma patients as a vulnerable population. Further efforts should optimize systems of care to maximize the chances of rescue for both mother and fetus.

Enhanced recovery and early extubation after pediatric cardiac surgery using single-dose intravenous methadone.

Background/Aims: Methadone may offer advantages in facilitating early extubation after cardiac surgery, but very few data are available in the pediatric population. Setting/Design: Community tertiary children's hospital, retrospective case series. Materials and Methods: We performed a retrospective analysis of all pediatric cardiac surgical patients for whom early extubation was intended. A multimodal analgesic regimen was used for all patients, consisting of methadone (0.2-0.3 mg/kg), ketamine (0.5 mg/kg plus 0.25 mg/kg/h), lidocaine (1 mg/kg plus 1.5 mg/kg/h), acetaminophen (15 mg/kg), and parasternal ropivacaine (0.5 mL/kg of 0.2%). Outcome variables were collected with descriptive statistics. Results: A total of 24 children [median = 7 (interquartile range = 3.75-13.75) years old, 23.7 (14.8-53.4) kg] were included in the study; 22 (92%) had procedures performed on bypass and 11 (46%) involved a reentry sternotomy. Methadone dosing was 0.26 (0.23-0.29) mg/kg. None of the children required intraoperative supplemental opioids; 23 (96%) were extubated in the operating room. The first paCO2 on pediatric intensive care unit admission was 51 (45-58) mmHg. Time to first supplemental opioid administration was 5.1 (3.5-9.5) h. Cumulative total supplemental opioids (in intravenous morphine equivalents) at 24 and 72 h were 0.2 (0.09-0.32) and 0.42 (0.27-0.68) mg/kg. One child required postoperative bilevel positive airway pressure support, but none required reintubation. None had pruritus; three (13%) experienced nausea. Conclusion: A methadone-based multimodal regimen facilitated early extubation without appreciable adverse events. Further investigations are needed to confirm efficacy of this regimen and to assess whether the excellent safety profile seen here holds in the hands of multiple providers caring for a larger, more heterogeneous population.

Medical Comanagement of Hip Fracture Patients Is Not Associated with Superior Perioperative Outcomes: A Propensity Score-Matched Retrospective Cohort Analysis of the National Surgical Quality Improvement Project.

BACKGROUND: Medical comanagement entails a significant commitment of clinical resources with the aim of improving perioperative outcomes for patients admitted with hip fractures. To our knowledge, no national analyses have demonstrated whether patients benefit from this practice. METHODS: We performed a retrospective cohort analysis of the American College of Surgeons (ACS) National Surgical Quality Improvement Program (NSQIP) targeted user file for hip fracture 2016-2017. Medical comanagement is a dedicated variable in the NSQIP. Propensity score matching was performed to control for baseline differences associated with comanagement. Matched pairs binary logistic regression was then performed to determine the effect of comanagement on the following primary outcomes: mortality and a composite endpoint of major morbidity. RESULTS: Unadjusted analyses demonstrated that patients receiving medical comanagement were older and sicker with a greater burden of comorbidities. Comanagement did not have a higher proportion of patients participating in a standardized hip fracture program (53.6% vs 53.7%; P > .05). Comanagement was associated with a higher unadjusted rate of mortality (6.9% vs 4.0%, odds ratio [OR] 1.79: 1.44-2.22; P < .0001) and morbidity (19.5% vs 9.6%, OR 2.28: 1.98-2.63; P < .0001). After propensity score matching was used to control for baseline differences associated with comanagement, patients in the comanagement cohort continued to demonstrate inferior mortality (OR 1.36: 1.02-1.81; P = .033) and morbidity (OR 1.82: 1.52-2.20; P < .0001). CONCLUSIONS: This analysis does not provide evidence that dedicated medical comanagement of hip fracture patients is associated with superior perioperative outcomes. Further efforts may be needed to refine opportunities to modify the significant morbidity and mortality that persists in this population.

Rotational thromboelastometry predicts transfusion and disability in pediatric trauma.

BACKGROUND: Trauma-induced coagulopathy seen on rotational thromboelastometry (ROTEM) is associated with poor outcomes in adults; however, this relationship is poorly understood in the pediatric population. We sought to define thresholds for product-specific transfusion and evaluate the prognostic efficacy of ROTEM in injured children. METHODS: Demographics, ROTEM, and clinical outcomes from severely injured children (age, < 18 years) admitted to a Level I trauma center between 2014 and 2018 were retrospectively analyzed. Receiver operating characteristic curves were plotted and Youden indexes were calculated against the endpoint of packed red blood cell transfusion to identify thresholds for intervention. The ROTEM parameters were compared against the clinical outcomes of mortality or disability at discharge. RESULTS: Ninety subjects were reviewed. Increased tissue factor-triggered extrinsic pathway (EXTEM) clotting time (CT) >84.5 sec (p = 0.049), decreased EXTEM amplitude at 10 minutes (A10) <43.5 mm (p = 0.025), and decreased EXTEM maximal clot firmness (MCF) <64.5 mm (p = 0.026) were associated with need for blood product transfusion. Additionally, EXTEM CT longer than 68.5 seconds was associated with mortality or disability at discharge. CONCLUSION: Coagulation dysregulation on thromboelastometry is associated with disability and mortality in children. Based on our findings, we propose ROTEM thresholds: plasma transfusion for EXTEM CT longer than 84.5 seconds, fibrinogen replacement for EXTEM A10 less than 43.5 mm, and platelet transfusion for EXTEM MCF less than 64.5 mm. LEVEL OF EVIDENCE: Prognostic, Level III; Therapeutic, Level IV.

Hospitalization Trends and Health Resource Use for Adult Congenital Heart Disease-Related Heart Failure.

Background This study assessed trends in heart failure ( HF) hospitalizations and health resource use in patients with adult congenital heart disease ( ACHD ). Methods and Results The Nationwide Inpatient Sample was used to compare ACHD with non- ACHD HF hospitalization and health resource trends. Health resource use was assessed using total hospital charges, hospital length of stay, and procedural burden. A total of 87 175±2676 ACHD -related HF hospitalizations occurred between 1998 and 2011. During this time, ACHD HF hospitalizations increased 91% (4620±438-8809±740, P<0.0001) versus a 21% increase in non- ACHD HF hospitalizations ( P=0.003). ACHD HF hospitalization was associated with longer length of stay ( ACHD HF versus non- ACHD HF, 7.2±0.09 versus 6.8±0.02 days; P<0.0001), greater procedural burden, and higher charges ($81 332±$1650 versus $52 050±$379; P<0.0001). ACHD HF hospitalization charges increased 258% during the study period ($26 533±$1816 in 1998 versus $94 887±$8310 in 2011; P=0.0002), more than double that for non- ACHD HF ( P=0.04). Patients with ACHD HF hospitalized in high-volume ACHD centers versus others were more likely to undergo invasive hemodynamic testing (30.2±0.6% versus 20.7±0.5%; P<0.0001) and to receive cardiac resynchronization/defibrillator devices (4.7±0.3% versus 1.8±0.2%; P<0.0001) and mechanical circulatory support (3.9±0.2% versus 2.4±0.2%; P<0.0001). Conclusions ACHD -related HF hospitalizations have increased dramatically in recent years and are associated with disproportionately higher costs, procedural burden, and health resource use.

Focused Review of Perioperative Care of Patients with Pulmonary Hypertension and Proposal of a Perioperative Pathway.

Morbidity and mortality risk increase considerably for patients with pulmonary hypertension (PH) undergoing non-cardiac surgery. Unfortunately, there are no comprehensive, evidence-based guidelines for perioperative evaluation and management of these patients. We present a brief review of the literature on perioperative outcomes for patients with PH and describe the implementation of a collaborative perioperative management program for these high-risk patients at a tertiary academic center.

Direct to operating room trauma resuscitation decreases mortality among severely injured children.

BACKGROUND: Expediting evaluation and intervention for severely injured patients has remained a mainstay of advanced trauma care. One technique, direct to operating room (DOR) resuscitation, for selective adult patients has demonstrated decreased mortality. We sought to investigate the application of this protocol in children. METHODS: All DOR pediatric patients from 2009 to 2016 at a pediatric Level I trauma center were identified. Direct to OR criteria included penetrating injury, chest injuries, amputations, significant blood loss, cardiopulmonary resuscitation, and surgeon discretion. Demographics, injury patterns, interventions, and outcomes were analyzed. Observed mortality was compared with expected mortality, calculated using Trauma Injury Severity Score methodology, with two-tailed t tests, and a p value less than 0.5 was considered significant. RESULTS: Of 2,956 total pediatric trauma activations, 82 (2.8%) patients (age range, 1 month to 17 years) received DOR resuscitation during the study period. The most common indications for DOR were penetrating injuries (62%) and chest injuries (32%). Forty-four percent had Injury Severity Score (ISS) greater than 15, 33% had Glasgow Coma Scale (GCS) score of 8 or less, and 9% were hypotensive. The most commonly injured body regions were external (66%), head (34%), chest (30%), and abdomen (27%). Sixty-seven (82%) patients required emergent procedural intervention, most commonly wound exploration/repair (35%), central venous access (22%), tube thoracostomy (19%), and laparotomy (18%). Predictors of intervention were ISS greater than 15 (odds ratio, 14; p = 0.013) and GCS < 9 (odds ratio = 8.5, p = 0.044). The survival rate to discharge for DOR patients was 84% compared with an expected survival of 79% (Trauma Injury Severity Score) (p = 0.4). The greatest improvement relative to expected mortality was seen in the subgroup with penetrating trauma (84.5% vs 74.4%; p = 0.002). CONCLUSION: A selective policy of resuscitating the most severely injured children in the OR can decrease mortality. Patients suffering penetrating trauma with the highest ISS, and diminished GCS scores have the greatest benefit. Trauma centers with appropriate resources should evaluate implementing similar policies. LEVEL OF EVIDENCE: Diagnostic tests or criteria, level II.

Outcomes following implantation of mechanical circulatory support in adults with congenital heart disease: An analysis of the Interagency Registry for Mechanically Assisted Circulatory Support (INTERMACS).

BACKGROUND: Adults with congenital heart disease represent an expanding and unique population of patients with heart failure (HF) in whom the use of mechanical circulatory support (MCS) has not been characterized. We sought to describe overall use, patient characteristics, and outcomes of MCS in adult congenital heart disease (ACHD). METHODS: All patients entered into the Interagency Registry for Mechanically Assisted Circulatory Support (INTERMACS) between June 23, 2006, and December 31, 2015, were included. Patients with ACHD were identified using pre-operative data and stratified by ventricular morphology. Mortality was compared between ACHD and non-ACHD patients, and multivariate analysis was performed to identify predictors of death after device implantation. RESULTS: Of 16,182 patients, 126 with ACHD stratified as follows: systemic morphologic left ventricle (n = 63), systemic morphologic right ventricle (n = 45), and single ventricle (n = 17). ACHD patients were younger (42 years ± 14 vs 56 years ± 13; p < 0.0001) and were more likely to undergo device implantation as bridge to transplant (45% vs 29%; p < 0.0001). A higher proportion of ACHD patients had biventricular assist device (BiVAD)/total artificial heart (TAH) support compared with non-ACHD patients (21% vs 7%; p < 0.0001). More ACHD patients on BiVAD/TAH support were INTERMACS profile 1 compared with patients on systemic left ventricular assist device (LVAD) support (35% vs 15%; p = 0.002). ACHD and non-ACHD patients with LVADs had similar survival; survival was worse for patients on BIVAD/TAH support. BiVAD/TAH support was the only variable independently associated with mortality (early phase hazard ratio 4.4; 95% confidence interval, 1.8-11.1; p = 0.001). For ACHD patients receiving MCS, ventricular morphology was not associated with mortality. CONCLUSIONS: ACHD patients with LVADs have survival similar to non-ACHD patients. Mortality is higher for patients requiring BiVAD/TAH support, potentially owing to higher INTERMACS profile. These outcomes suggest a promising role for LVAD support in ACHD patients as part of the armamentarium of therapies for advanced HF.

Trends in Hospitalization for Pediatric Pulmonary Hypertension.

BACKGROUND AND OBJECTIVES: Pulmonary hypertension (PH) has been associated with substantial morbidity and mortality in children, but existing analyses of inpatient care are limited to small single-institution series or focused registries representative of selected patient subgroups. We examined US national data on pediatric PH hospitalizations to determine trends in volume, demographics, procedures performed during admission, and resource utilization. METHODS: Retrospective cohort study using a national administrative database of pediatric hospital discharges: the Kids' Inpatient Database. RESULTS: Children with PH accounted for 0.13% of the 43 million pediatric hospitalizations in the United States between 1997 and 2012, and discharges demonstrated an increasing trend over the study period (P < .0001). Cumulative, inflation-adjusted national hospital charges for PH hospitalizations rose (P = .0003) from $926 million in 1997 to $3.12 billion in 2012. Patients with PH without associated congenital heart disease (CHD) comprised an increasing and majority (56.4%) proportion over the study period (P < .0001), children without associated CHD admitted at urban teaching hospitals comprised the fastest-growing subgroup. In-hospital, all-cause mortality was high (5.9%) in children with PH, but demonstrated a decreasing trend (P < .0001). CONCLUSIONS: Morbidity and mortality of pediatric PH continue to represent substantial and growing health care burdens. Shifts in case mix toward PH not associated with CHD, toward noncardiac procedures, and toward care in urban teaching hospitals will increase pressure to manage resource utilization in this small but growing patient group and to improve expertise and define excellence in PH care across a wide range of clinical settings.

Obstructive Sleep Apnea Is an Independent Predictor of Postoperative Atrial Fibrillation in Cardiac Surgery.

OBJECTIVE: To test the hypothesis that obstructive sleep apnea (OSA) is a risk factor for development of postoperative atrial fibrillation (POAF) after cardiac surgery. DESIGN: Retrospective analysis. SETTING: Single-center university hospital. PARTICIPANTS: Five hundred forty-five patients in sinus rhythm preoperatively undergoing coronary artery bypass grafting (CABG), aortic valve replacement, mitral valve replacement/repair, or combined valve/CABG surgery from January 2008 to April 2011. INTERVENTIONS: Retrospective review of medical records. MEASUREMENTS AND MAIN RESULTS: Postoperative atrial fibrillation was defined as atrial fibrillation requiring therapeutic intervention. Of 545 cardiac surgical patients, 226 (41%) patients developed POAF. The risk was higher in 72 OSA patients than 473 patients without OSA (67% v 38%, adjusted hazard ratio 1.83 [95% CI: 1.30-2.58], p<0.001). Of the 32 OSA patients who used home positive airway pressure (PAP) therapy, 18 (56%) developed POAF compared with 29 of 38 (76%) patients who did not use PAP at home (unadjusted hazard ratio 0.63 [95% CI: 0.35-1.15], p = 0.13). CONCLUSION: OSA is significantly associated with POAF in cardiac surgery patients. Further investigation is needed to determine whether or not use of positive airway pressure in OSA patients reduces the risk of POAF.

Complications of catheter-based electrophysiology procedures in adults with congenital heart disease: a national analysis.

OBJECTIVE: To determine whether adult congenital heart disease patients (ACHD) undergoing catheter-based electrophysiology (EP) procedures have an increased risk for complications compared with adults without congenital heart disease. DESIGN: Retrospective cohort study of a national administrative database. SETTING: Nationwide Inpatient Sample, 1998 through 2011. PARTICIPANTS: All admission records of patients who underwent a catheter-based electrophysiology procedure, categorized based on the presence or absence of ACHD. INTERVENTIONS: ACHD and non-ACHD cohorts were compared with respect to baseline, procedural, and outcome characteristics. MEASUREMENTS AND MAIN RESULTS: ACHD patients accounted for n=15,133 (1.7%) of n=873,437 EP procedure admissions and comprised a significantly increasing proportion over the study period (from 0.8% in 1998 to 2.4% in 2011, p<0.0001). ACHD patients were younger than non-ACHD patients (52.5±0.3 years v 61.9±0.04 years; p<0.0001), had a longer length of stay (4.6±0.1 days v 4.4±0.01 days, p=0.013), higher total hospital charges ($89,485±$1,543 v $70,456±$175, p<0.0001), and a higher rate of procedure-related complications (odds ratio 1.66, 95% confidence interval 1.49-1.85, p<0.0001). On multivariate analysis, ACHD patients continued to demonstrate an increased risk of procedural complications (odds ratio 1.95, 95% confidence interval 1.75-2.19, p<0.0001). CONCLUSIONS: ACHD patients experienced greater morbidity after catheter-based EP procedures. This finding will be of increasing significance as ACHD patients occupy a growing segment of the population undergoing these procedures. Further investigations are warranted to determine whether this increased risk is modifiable, with the aim of improving patient safety.

Increased resource use in lung transplant admissions in the lung allocation score era.

RATIONALE: In 2005, the lung allocation score (LAS) was implemented to prioritize organ allocation to minimize waiting-list mortality and maximize 1-year survival. It resulted in transplantation of older and sicker patients without changing 1-year survival. Its effect on resource use is unknown. OBJECTIVES: To determine changes in resource use over time in lung transplant admissions. METHODS: Solid organ transplant recipients were identified within the Nationwide Inpatient Sample (NIS) data from 2000 to 2011. Joinpoint regression methodology was performed to identify a time point of change in mean total hospital charges among lung transplant and other solid-organ transplant recipients. Two temporal lung transplant recipient cohorts identified by joinpoint regression were compared for baseline characteristics and resource use, including total charges for index hospitalization, charges per day, length of stay, discharge disposition, tracheostomy, and need for extracorporeal membrane oxygenation. MEASUREMENTS AND MAIN RESULTS: A significant point of increased total hospital charges occurred for lung transplant recipients in 2005, corresponding to LAS implementation, which was not seen in other solid-organ transplant recipients. Total transplant hospital charges increased by 40% in the post-LAS cohort ($569,942 [$53,229] vs. $407,489 [$28,360]) along with an increased median length of stay, daily charges, and discharge disposition other than to home. Post-LAS recipients also had higher post-transplant use of extracorporeal membrane oxygenation (odds ratio, 2.35; 95% confidence interval, 1.56-3.55) and higher incidence of tracheostomy (odds ratio, 1.52; 95% confidence interval, 1.22-1.89). CONCLUSIONS: LAS implementation is associated with a significant increase in resource use during index hospitalization for lung transplant.
