Association of rurality with short-term outcomes of peripheral vascular trauma.

BACKGROUND: Peripheral vascular trauma is a major contributing factor to long-term disability and mortality among patients with traumatic injuries. However, an analysis focusing on individuals at a high risk of experiencing limb loss due to rural and urban peripheral vascular trauma is lacking. METHOD: This was a retrospective analysis of the 2016 to 2020 Nationwide Readmissions Database. Patients (≥18 years) undergoing open or endovascular procedures after admission for peripheral vascular trauma were identified using the 2016 to 2020 Nationwide Readmissions Database. Patients from rural regions were considered Rural, whereas the remainder comprised Urban. The primary outcome of the study was primary amputation. Multivariable regression models were developed to evaluate rurality with outcomes of interest. RESULTS: Of 29,083 patients, 4,486 (15.6%) were Rural. Rural were older (41 [28-59] vs 37 [27-54] years, P < .001), with a similar distribution of female sex (23.0 vs 21.3%, P = .09) and transfers from other facilities (2.8 vs 2.5%, P = .34). After adjustment, Rural status was not associated with the odds of mortality (P = .82), with urban as reference. Rural status was, however, associated with greater odds of limb amputation (adjusted odds ratio 1.85, 95% confidence interval 1.47-2.32) and reduced index hospitalization cost by $7,100 (95% confidence interval $3,500-10,800). Additionally, compared to patients from urban locations, rurality was associated with similar odds of non-home discharge and 30-day readmission. Over the study period, the marginal effect of rurality on the risk-adjusted rates of amputation significantly increased (P < .001). CONCLUSION: Patients who undergo peripheral vascular trauma management in rural areas appear to increasingly exhibit a higher likelihood of amputation, with lower incremental costs and a lower risk of 30-day readmission. These findings underscore disparities in access to optimal trauma vascular care as well as limited resources in rural regions.

Association of prior bariatric surgery with outcomes following emergency general surgery.

BACKGROUND: Despite the favorable outcomes and safety profile associated with metabolic and bariatric surgery (MBS), complications may occur postoperatively, necessitating emergency general surgery (EGS) intervention. OBJECTIVES: To evaluate the association of outcomes in patients with prior MBS following EGS interventions. SETTING: Academic, University-affiliated; USA. METHODS: All adults undergoing nonelective EGS operations were identified using the 2016 to 2020 Nationwide Readmission Database. Patients with a history of MBS were subsequently categorized as Bariatric, with the remainder of patients as NonBariatric. The primary outcome of interest was in-hospital mortality, while perioperative complications, length of stay (LOS), hospitalization costs, non-home discharge, and 30-day readmission were secondarily assessed. Multivariable regression models were developed to evaluate the association of history of MBS with outcomes of interest. RESULTS: Of an estimated 632,375 hospitalizations for EGS operations, 29,112 (4.6%) had a history of MBS. Compared to Nonbariatric, Bariatric were younger, more frequently female and more commonly had severe obesity. Following risk adjustment, Bariatric had significantly lower odds of in-hospital mortality (AOR .83, 95%CI .71-.98). Compared to others, Bariatric had reduced LOS by .5 days (95%CI .4-.7) and hospitalization costs by $1600 (95%CI $900-2100). Patients with prior MBS had reduced odds of nonhome discharge (AOR .89, 95%CI .85-.93) and increased likelihood of 30-day readmissions (AOR 2.32, 95%CI 1.93--2.79) following EGS. CONCLUSIONS: Prior MBS is associated with decreased mortality and perioperative complications as well as reduced resource utilization in select EGS procedures. Our findings suggest that patients with a history of MBS can be managed effectively by acute surgical interventions.

National Trends and Clinical Outcomes after Scooter Injury in the US: 2016 to 2020.

BACKGROUND: In recent years, the adoption of electric scooters has been accompanied by a surge of scooter-related injuries in the US, raising concerns for their severity and associated healthcare costs. This study aimed to assess temporal trends and outcomes of scooter-related hospital admissions compared with bicycle-related hospitalizations. STUDY DESIGN: This was a retrospective cohort study using the 2016 to 2020 National Inpatient Sample for patients younger than 65 years who were hospitalized after bicycle- and scooter-related injuries. The Trauma Mortality Prediction Model was used to quantify injury severity. The primary outcomes of interest were temporal trends of micromobility injuries. In-hospital mortality, rates of long bone fracture, traumatic brain injury, paralysis, length of stay, hospitalization costs, and nonhome discharge were secondarily assessed. RESULTS: Among 92,815 patients included in the study, 6,125 (6.6%) had scooter-related injuries. Compared with patients with bicycle-related injuries, patients with scooter-related injuries were more commonly younger than 18 years (26.7% vs 16.4%, p < 0.001) and frequently underwent major operations (55.8% vs 48.1%, p < 0.001). After risk adjustment, scooter-related injuries were associated with greater risks of long bone fracture (adjusted odds ratio 1.40, 95% CI 1.15 to 1.70) and paralysis (adjusted odds ratio 2.06, 95% CI 1.16 to 3.69) compared with bicycle-related injuries. Additionally, patients with bicycle- or scooter-related injuries had comparable index hospitalization durations of stay and costs. CONCLUSIONS: The prevalence and severity of scooter-related injuries have significantly increased in the US, thereby attributing to a substantial cost burden on the healthcare system. Multidisciplinary efforts to inform safety policies and enact targeted interventions are warranted to reduce scooter-related injuries.

Outcomes of Hospitalized Injured Suspects Sustaining Gunshot Wounds From Law Enforcement Action.

BACKGROUND: Although firearms are implicated in the majority of law enforcement intervention (LEI)-related deaths, scientific research is lacking. The present study sought to characterize clinical and financial outcomes between injured suspects and other gunshot wound (GSW) patients. STUDY DESIGN: The 2016-2020 National Inpatient Sample was queried for patients ≥16 years old admitted following GSW. Patients were categorized as injured suspects (ISs) if they were injured in LEI and non-IS otherwise. The primary outcome was in-hospital mortality with complications, hospitalization duration (LOS), and costs secondarily considered. Multivariable regression models were used to adjust for patient characteristics, injury burden using the Trauma Mortality Prediction Model (TMPM), and hospital factors. RESULTS: Of 143,125 hospitalizations, 1575 (1.10%) were IS. Compared to non-IS, ISs were less frequently Black (24.4% vs 54.3%) but had a higher proportion of psychiatric conditions (19.4% vs 6.4%) (P < .05). Although having a similar requirement for major operations and TMPM score, ISs more frequently underwent thoracic (11.4% vs 4.1%) and gastrointestinal operations (33.0% vs 25.7%) (P < .05). After adjustment, IS was associated with similar odds of mortality but was associated with greater odds of cardiac complications, respiratory failure, and need for intensive care. While LOS was similar, IS was associated with greater costs (ß: +$14,300, 95% CI: 6,200-22,400). CONCLUSIONS: Suspects injured during law enforcement intervention have similar in-hospital mortality but greater complication rates and costs. Through the quantification of the clinical and financial burden of IS, our findings may help inform further policy discussions regarding use of potentially lethal force in law enforcement intervention.

Association of Early Rib Plating on Clinical and Financial Outcomes: A National Analysis.

BACKGROUND: With reported improvements in patient outcomes, surgical stabilization of rib fractures (SSRF) has been increasingly adopted. While institutional series have sought to define the role of early SSRF, large scale analysis remains lacking. The present study evaluated clinical and financial outcomes of SSRF in a nationally representative cohort. METHODS: Patients (≥16 years) admitted with multiple rib fractures were identified using the 2016-2020 National Inpatient Sample. Those who underwent rib plating >14 days following admission were omitted. Using restricted cubic spline analysis, patients who underwent SSRF within 2 days of hospitalization were classified as Expedited while fixation >2 days were deemed Routine. Multivariable regressions were used to evaluate the association of operative timing on outcomes of interest. RESULTS: Of 8150 patients meeting final inclusion criteria, 4090 (50.2%) were Expedited. Compared to Routine, Expedited tended to be older but were of comparable race, primary payer, and income quartile. Traumatic mechanism was also similar but rates of concomitant sternal fracture as well as intra-abdominal and cardiac injuries were higher in Routine. After adjustment, Expedited was associated with lower odds of respiratory complications, which included need for mechanical ventilation, prolonged mechanical ventilation, and pneumonia, compared to Routine. Expedited was associated with similar hospitalization duration but had lower incremental costs (ß: -$19.1 K, 95% CI: -24.1 to -14.2). DISCUSSION: Early SSRF was associated with lower likelihood of a number of respiratory complications and in-hospital costs. While patient selection criteria may limit our findings, expeditious fixation may limit morbidity while enhancing value of care.

A Medium-Term Comparison of Quality of Life and Pain After Robotic or Laparoscopic Cholecystectomy.

INTRODUCTION: We sought to compare medium-term outcomes between robotic-assisted cholecystectomy (RC) and laparoscopic cholecystectomy (LC) using validated quality of life (QoL) and pain assessments. MATERIALS AND METHODS: Patients who underwent RC or LC between 2012 and 2017 at a single academic institution were examined. Cases converted to open were excluded. Patients were contacted by telephone in 2019 and completed two standardized surveys to rate their QoL and pain. RESULTS: Of those screened, 122 (35.8%) completed both surveys. Ninety three (76.2%) underwent RC and 29 (23.8%) underwent LC. The groups (RC versus LC) were similar based on mean age (47.9 versus 45.5 y, P = 0.48), gender (66.7% versus 72.4% female, P = 0.56), race (86.0% White/5.4% Black versus 72.4% White/13.8% Black, P = 0.2), insurance status (98.9% versus 100.0% insured, P = 0.58), median body mass index (31.8 versus 31.3, P = 0.43), and median Charlson Comorbidity Index (1 versus 0, P = 0.14). Fewer RC patients had a history of steroid use compared to LC (16.1% versus 34.5%, P = 0.03). No overall significant difference in QoL was demonstrated. LC group had higher severity of "tiring-exhausting pain" (P = 0.04), "electric-shock pain" (P = 0.003), and "shooting pain" (P = 0.05). The "overall intensity" of pain in the "gallbladder region" between the groups was similar at the time of follow-up (P = 0.31). CONCLUSIONS: QoL over 2-7 y following time of surgery is comparable for robotic-assisted versus conventional laparoscopic cholecystectomies. The laparoscopic approach may be associated with a higher severity of subset categories of pain, but overall pain between the two approaches is comparable.

The Order of Operative Repair Does Not Influence Outcomes in Patients with Concomitant Popliteal Artery and Orthopedic Injuries.

BACKGROUND: The most challenging lower extremity traumatic injuries involve concomitant vascular and orthopedic injuries with amputation rates approaching 50%. Controversy exists as to how to prioritize the vascular and orthopedic repairs. We reviewed patients with popliteal artery and lower extremity orthopedic injuries to analyze the sequence of the vascular and orthopedic repairs on outcomes. METHODS: All adult patients with a diagnosis of concomitant popliteal artery and lower extremity fracture or dislocation were identified through a review of an institutional trauma registry performed at a level 1 trauma center from 2014 to 2019. Patient demographics, timing of presentation, injury severity score (ISS), surgical interventions, and limb outcome data were collected and examined. The sequence of operative repairs and factors influencing the operative order were analyzed. RESULTS: Twenty-nine patients were treated for popliteal artery injuries. Twelve of these 29 patients had concomitant popliteal artery and orthopedic fractures requiring surgical repair. Injury mechanisms included both blunt (50%, 6/12) and penetrating trauma (50%, 6/12); the majority involved femur fractures (58%, 7/12). Vascular repair included arterial bypass (75%, 9/12) or interposition grafts (25%, 3/12). Orthopedic repair included external fixation (83%, 10/12) and open reduction internal fixation (17%, 2/12). Vascular repair was performed first in 7/12 limbs (58%). Patients having vascular repair first had a trend toward lower blood pressure on arrival (P = 0.068). There was no significant difference in emergency department to operating room (OR) time, OR time, ISS, mangled extremity severity score, estimated blood loss, or blood transfusion for the sequence of operative repair. Fasciotomy was nearly ubiquitous, present in 11/12 patients (92%). There were no graft complications related to orthopedic manipulation, and there were no reported limb-length to graft-length discrepancies. Early limb salvage trended lower in the cohort with revascularization first (71% vs. 100%, P = 0.19). Of the remaining limbs available for follow-up, limb salvage at 4.25 years is 100%. CONCLUSIONS: In this small study of patients with concomitant lower extremity popliteal artery and orthopedic injuries, the order of operative repair does not appear to influence the success of revascularization.

Analysis of Extracranial Cerebrovascular Injuries: Clinical Predictors of Management and Outcomes.

BACKGROUND: Optimal management of traumatic extracranial cerebrovascular injuries (ECVIs) remains undefined. We sought to evaluate the factors that influence management and neurologic outcomes (stroke and brain death) following traumatic ECVI. METHODS: A retrospective review of a single level 1 trauma center's prospectively maintained data registry of patients older than 18 years of age with a diagnosis of ECVI was performed from 2013 to 2019. Injuries limited to the external carotid artery were excluded. Patient demographics, type of injury, timing of presentation, Biffl Classification of Cerebrovascular Injury Grade, Injury Severity Score (ISS), and Abbreviated Injury Scale were documented. Ultimate treatments (medical management and procedural interventions) and brain-related outcomes (stroke and brain death) were recorded. RESULTS: ECVIs were identified in 96 patients. The primary mechanism of injury was blunt trauma (89.5% vs. 10.5%, blunt versus penetrating), with 70 cases (66%) of vertebral artery injury and 37 cases of carotid artery injury. Treatments included vascular intervention (6.5%) and medical management (93.5%). Overall outcomes included ipsilateral ischemic stroke (29%) and brain death (6.5%). In the carotid group, vascular intervention was associated with higher Biffl grades (mean Biffl 3.17 vs. 2.23; P = 0.087) and decreased incidence of brain death (0% vs. 19%, P = 0.006), with no difference seen in ISS scores. Brain death was associated with higher ISS scores (40.29 vs. 24.17, P = 0.01), lower glascow coma score on arrival (3.57 vs. 10.63, P < 0.001), and increased rates of ischemic stroke (71% vs. 30%, P = 0.025). In the vertebral group, neither Biffl grade nor ISS were associated with treatment or outcomes. Regarding the timing of stroke in ECVI, there was no significant difference in the time from presentation to cerebral infarction between the carotid and vertebral artery groups (24.7 hr vs. 21.20 hr, P = 0.739). After this window, 98% of the ECVI cases demonstrated no further aneurysmal degeneration or new neurological deficits beyond the early time period (mean follow-up 9.7 months). CONCLUSIONS: Blunt cerebrovascular injuries should be viewed distinctly in the carotid and vertebral territories. In cases of injury to the carotid artery, Biffl grade and ISS score are associated with surgical intervention and neurologic events, respectively; vertebral artery injuries did not share this association. Neurologic deficits were detected in a similar time frame between the carotid artery and the vertebral artery injury groups and both groups had rare late neurologic events.

Medical Management of Traumatic Vertebral Artery Injury Is Safe Regardless of the Severity of Injury.

BACKGROUND: Management of traumatic vertebral artery injury (VAI) remains under debate. Current consensus reserves surgical or endovascular management for high-grade injury in order to prevent stroke. We sought to evaluate the factors that influence posterior fossa stroke outcomes following traumatic VAI. METHODS: A search of the prospectively maintained PROOVIT trauma registry of patients older than 18 years of age with a diagnosis of VAI was performed at a level 1 trauma center from 2013 to 2019. Patient demographics, type of injury, the timing of presentation, Biffl Classification of Cerebrovascular Injury Grade score, medical management, procedural interventions, and stroke outcomes were analyzed. RESULTS: VAIs were identified in 66 trauma patients were identified out of 14,323 patients entered into the PROOVIT registry. The dominant mechanism was blunt injury (91.5% vs. 8.5%, blunt versus penetrating). Nine patients presented with symptomatic ipsilateral posterior circulation strokes visible on imaging. The average Biffl classification grade was similar between the stroke and nonstroke groups (2.0 vs. 1.5; P = 0.39). The average injury severity score (ISS) between stroke and nonstroke groups was also similar (9.0 vs. 14.0; P = 0.35). All 9 patients in the stroke group had magnetic resonance imaging verification of their infarct within an average of 21.2 hr from presentation. In the stroke group, 1 patient underwent diagnostic angiography but had no intervention. In the nonstroke group, all were treated with medical management alone and none underwent vertebral artery intervention. During a mean follow-up of 14.5 months, no patients experienced a new neurological deficit. CONCLUSIONS: The severity of VAI by Biffl grading and ISS are not associated with ischemic stroke at presentation following VAI. Medical management of VAI appears safe regardless of Biffl and ISS staging in this trauma population. Neurological changes related to embolic stroke were generally appreciated on presentation. Conservative medical management was sufficient to protect from secondary neurological deficit regardless of index vertebral injury.

National trends and resource associated with recurrent penetrating injury.

BACKGROUND: While recurrent penetrating trauma has been associated with long-term mortality and disability, national data on factors associated with reinjury remain limited. We examined temporal trends, patient characteristics, and resource utilization associated with repeat firearm-related or stab injuries across the US. METHODS: This was a retrospective study using 2010-2019 Nationwide Readmissions Database (NRD). NRD was queried to identify all hospitalizations for penetrating trauma. Recurrent penetrating injury (RPI) was defined as those returned for a subsequent penetrating injury within 60 days. We quantified injury severity using the International Classification of Diseases Trauma Mortality Prediction model. Trends in RPI, length of stay (LOS), hospitalization costs, and rate of non-home discharge were then analyzed. Multivariable regression models were developed to assess the association of RPI with outcomes of interest. RESULTS: Of an estimated 968,717 patients (28.4% Gunshot, 71.6% Stab), 2.1% experienced RPI within 60 days of the initial injury. From 2010 to 2019, recurrent gunshot wounds increased in annual incidence while that of stab cohort remained stable. Patients experiencing recurrent gunshot wounds were more often male (88.9 vs 87.0%, P<0.001), younger (30 [23-40] vs 32 [24-44] years, P<0.001), and less commonly insured by Medicare (6.5 vs 11.2%, P<0.001) compared to others. Those with recurrent stab wounds were younger (36 [27-49] vs 44 [30-57] years, P<0.001), less commonly insured by Medicare (21.3 vs 29.3%, P<0.001), and had lower Elixhauser Index Comorbidities score (2 [1-3] vs 3 [1-4], P<0.001) compared to others. After risk adjustment, RPI of both gunshot and stab was associated with significantly higher hospitalization costs, a shorter time before readmission, and increased odds of non-home discharge. CONCLUSION: The trend in RPI has been on the rise for the past decade. National efforts to improve post-discharge prevention and social support services for patients with penetrating trauma are warranted and may reduce the burden of RPI.

Bias in artificial intelligence in vascular surgery.

Application of artificial intelligence (AI) has revolutionized the utilization of big data, especially in patient care. The potential of deep learning models to learn without a priori assumption, or without prior learning, to connect seemingly unrelated information mixes excitement alongside hesitation to fully understand AI's limitations. Bias, ranging from data collection and input to algorithm development to finally human review of algorithm output affects AI's application to clinical patient presents unique challenges that differ significantly from biases in traditional analyses. Algorithm fairness, a new field of research within AI, aims to mitigate bias by evaluating the data at the preprocessing stage, optimizing during algorithm development, and evaluating algorithm output at the postprocessing stage. As the field continues to develop, being cognizant of the inherent biases and limitations related to black box decision making, biased data sets agnostic to patient-level disparities, wide variation of present methodologies, and lack of common reporting standards will require ongoing research to provide transparency to AI and its applications.

Prospective Assessment of Social Determinants of Health and Length of Stay Among Emergency General Surgery and Trauma Patients.

BACKGROUND: Social determinants of health (SDOH) including insurance and substance use affect 50-90% of health outcomes, yet there remains no standard means to quantify or predict their impact. We prospectively evaluated the effects of SDOH on length of stay (LOS) and readmissions among emergency general surgery (EGS) and trauma patients. We compared these outcomes with Medicare Diagnosis Related Group (DRG) data to better quantify the impact of SDOH. METHODS: Adult (≥18 years old) EGS/trauma patients admitted July 7-28, 2020 at a Level 1 trauma center were prospectively enrolled. Primary outcomes were overall LOS, one-year readmissions, and excess LOS (eLOS), defined as days beyond DRG mean LOS. RESULTS: Assessment of SDOH among the 52 patients enrolled revealed that 5.8% of patients were homeless; 26.9% experienced substance abuse; 13.5% were uninsured on admission; and 7.7% on discharge. Mean LOS was 5 ± 4 days; 1-year readmission rate 25.0%; eLOS mean 1.75 ± 2.4 days. LOS was associated with substance use (OR 70.6 95% CI 11.7-160.4). eLOS was associated with substance use (OR 6.1, 95% CI 1.5-25.1) and public or no insurance (OR 26.0, 95% CI 4.9-138.1). No correlations were found between SDOH and readmission rates. DISCUSSION: EGS and trauma patients experience high rates of negative SDOH which affect clinical outcomes including LOS and readmissions. Medicare DRG determined eLOS is a fiscally relevant measure of the impact of SDOH and differs from LOS and readmissions. Further investigation is required to determine if eLOS can delineate the effects of other SDOH on admission outcomes for this patient population.

Clinical and financial outcomes of transplant recipients following emergency general surgery operations.

Introduction: Due to immunosuppression and underlying comorbidities, transplant recipients represent a vulnerable population following emergency general surgery (EGS) operations. The present study sought to evaluate clinical and financial outcomes of transplant patients undergoing EGS. Methods: The 2010-2020 Nationwide Readmissions Database was queried for adults (≥18 years) with non-elective EGS. Operations included bowel resection, perforated ulcer repair, cholecystectomy, appendectomy and lysis of adhesions. Patients were classified by transplant history (Non-transplant, Kidney/Pancreas, Liver, Heart/Lung). The primary outcome was in-hospital mortality while perioperative complications, resource utilization and readmissions were secondarily considered. Multivariable regression models evaluated the association of transplant status on outcomes. Entropy balancing was employed to obtain a weighted comparison to adjust for intergroup differences. Results: Of 7,914,815 patients undergoing EGS, 25,278 (0.32 %) had prior transplantation. The incidence of transplant patients increased temporally (2010: 0.23 %, 2020: 0.36 %, p < 0.001) with Kidney/Pancreas comprising the largest proportion (63.5 %). Non-transplant more frequently underwent appendectomy and cholecystectomy while transplant patients more commonly received bowel resections. Following entropy balancing, Liver was associated with decreased odds of mortality (AOR: 0.67, 95 % CI: 0.54-0.83, Reference: Non-transplant). Incremental hospitalization duration was longer in Liver and Heart/Lung compared to Non-transplant. Odds of acute kidney injury, readmissions and costs were higher in all transplant types. Conclusion: The incidence of transplant recipients undergoing EGS operations has increased. Liver was observed to have lower mortality compared to Non-transplant. Transplant recipient status, regardless of organ, was associated with greater resource utilization and non-elective readmissions. Multidisciplinary care coordination is warranted to mitigate outcomes in this high-risk population.

Factors Associated With Early Amputation in Patients With Chronic Limb Threatening Ischemia.

INTRODUCTION: Despite advancements in revascularization procedures, early amputation (EA) among patients with chronic limb threatening ischemia (CLTI) are still common. The present study evaluated clinical outcomes of patients with CLTI and factors associated with EA. METHODS: The 2016-2019 Nationwide Readmission Database was queried to identify all adults (≥18 years) with CLTI of lower extremities undergoing limb salvage (LS) procedures. The primary outcome of the study was EA within 90 days of discharge. Secondary outcomes included infectious complication, length of stay (LOS), cumulative hospitalization cost and non-home discharge. RESULTS: Of 103,703 patients who initially underwent surgical or endovascular revascularization, 10,439 (10.1%) subsequently underwent major amputation within 90 days of discharge. Following risk adjustment, factors associated with higher odds of EA were male sex, low-income quartile, tissue loss due to ulceration or gangrene, end-stage renal disease, and diabetes. Compared to those undergoing open revascularization, patients with endovascular limb salvage had a higher likelihood of having early amputation (AOR 1.41, 95% CI 1.31-1.51). Patients undergoing EA had greater odd of infectious complication, incremental LOS, incremental cost and non-home discharge. CONCLUSIONS: We identified several risk factors to be associated with EA in patients with CLTI. These findings may supplement the objective performance goals for limb-related outcomes and facilitate institutional limb salvage programs.

An Ounce of Prevention is the Only Cure: Nationwide Clinical and Financial Outcomes of Self-Inflicted Firearm Injuries.

BACKGROUND: Self-inflicted gunshot wounds (SIGSWs) remain a leading, preventable cause of death in the United States. The present study evaluated patient demographics, operative characteristics, in-hospital outcomes, and resource utilization between patients with SIGSW and other GSW. METHODS: The 2016-2020 National Inpatient Sample was queried for patients ≥16 years old admitted following gunshot wounds. Patients were categorized as SIGSW if they were injured through self-harm. Multivariable logistic regression was used to evaluate the association of SIGSW on outcomes. The primary endpoint was in-hospital mortality with complications, costs, and length of stay secondarily considered. RESULTS: Of an estimated 157,795 surviving to hospital admission, 14,670 (9.30%) were SIGSW. Self-inflicted gunshot wounds were more commonly female (18.1 vs 11.3%), insured by Medicare (21.1 vs 5.0%), and white (70.8 vs 22.3%) (all P < .001) compared to non-SIGSW. Psychiatric illness was more prevalent in SIGSW (46.0 vs 6.6%, P < .001). Additionally, SIGSW more frequently underwent neurologic (10.7 vs 2.9%) and facial operations (12.5 vs 3.2%) (both P < .001). After adjustment, SIGSW was associated with greater odds of mortality (AOR: 12.4, 95% CI: 10.4-14.7). Length of stay (ß: +1.5 days, 95% CI: .8-2.1) and costs (ß: +$3.6 K, 95% CI: 1.4-5.7) were significantly greater in SIGSW. CONCLUSIONS: Self-inflicted gunshot wounds are associated with increased mortality compared to other GSW, likely due to the increased proportion of injuries in the head and neck region. This lethality, coupled with the high prevalence of psychiatric illness in this population, indicates that efforts must be made to intervene through primary prevention, including enhanced screening and weapon safety considerations for those at risk.

National trends and clinical outcomes of interventional approaches following admission for infected necrotizing pancreatitis in the United States.

BACKGROUND: With recent studies demonstrating the efficacy of minimally invasive approaches following infected necrotizing pancreatitis, latest guideline recommendations support their use. However, large-scale studies are lacking, and the national landscape following these guidelines remains poorly characterized. The present study examined trends in intervention strategies and the association of approach on clinical outcomes and resource use in a nationally representative cohort. METHODS: The 2016-2019 National Inpatient Sample was queried for adult hospitalizations for pancreatitis with infected necrosis. Patients were classified as drain only (DO) if they received only percutaneous or endoscopic drainage, minimally invasive (MIS) if they underwent endoscopic or laparoscopic debridement, and Open if they underwent open debridement. The primary outcome was in-hospital mortality, while secondary outcomes included perioperative complications, home discharge, and resource use. Multivariable regression models were developed to evaluate the association of intervention with clinical and financial endpoints. RESULTS: Of 4,605 patients who received interventions, 1,735 (37.6%) were DO, 1,490 (32.4%) were MIS, and 1,380 (30.0%) were considered Open. The proportion of DO and MIS increased, while Open declined (2016, 47.0%; 2019, 24.6%; p < 0.001). Compared with Open, MIS had lower rates of abdominal compartment syndrome while having greater rates of preoperative closed drainage (31.9% vs. 13.8%, p < 0.001). After adjustment, odds of in-hospital mortality, respiratory failure, prolonged ventilation, and acute kidney injury were significantly higher in the Open cohort compared with MIS. Hospitalization duration was longer ( ß , +12.1 days; 95% confidence interval, 6.8-17.5), and costs were higher ( ß , +$58.7K; 95% confidence interval, 33.5-83.9) in Open compared with MIS. CONCLUSION: Minimally invasive approaches for infected pancreatic necrosis have increased over time, while open necrosectomy has declined. Open approaches compared with drainage only or minimally invasive debridement were associated with greater odds of numerous in-hospital complications and resource burden. LEVEL OF EVIDENCE: Prognostic and Epidemiological; Level IV.

Transcatheter and Surgical Aortic Valve Replacement in Patients With Bicuspid Aortic Valve Stenosis.

BACKGROUND: Transcatheter aortic valve replacement (TAVR) is not widely used in patients with bicuspid aortic valve (BAV) disease and has not yet been studied in randomized clinical trials. We characterized the rate of use and outcomes of TAVR and surgical aortic valve replacement (SAVR) in patients with BAV. METHODS: Adults with BAV stenosis receiving SAVR or TAVR procedures were abstracted from the 2012 to 2019 Nationwide Readmissions Database (NRD). Risk-adjusted analyses were performed with NRD-provided weights and inverse probability of treatment weights (IPTW) to examine the association of treatment strategy on inpatient mortality, complications, and hospitalization resource utilization. Nonelective readmissions within 90 days of discharge and reintervention at the first readmission were also examined. RESULTS: Of an estimated 56 331 patients with BAV requiring aortic valve replacement, 6.8% underwent TAVR. Unadjusted analysis demonstrated higher index hospitalization mortality for TAVR compared with SAVR. Upon risk adjustment using NRD-provided weights, the odds of pacemaker implantation remained significantly higher for TAVR patients compared with SAVR, with no significant difference in mortality. When NRD-provided survey weights were applied, TAVR had higher rates of 90-day readmission. Adjustment with inverse probability of treatment weights resolved these differences between the 2 groups. Regardless of the risk-adjustment method, the odds of reintervention were consistently higher among BAV TAVR patients compared with SAVR. CONCLUSIONS: The present analysis demonstrates comparable in-hospital mortality and morbidity for TAVR and SAVR patients in the moderate-risk era. With increasing TAVR use in BAV, surgeons must further refine selection criteria with consideration of concomitant aortopathy and implications of reintervention.

Care Fragmentation After Hospitalization for Acute Myocardial Infarction.

Care fragmentation (CF), or readmission at a nonindex hospital, has been linked to inferior clinical and financial outcomes for patients. However, its impact on patients with acute myocardial infarction (AMI) is unclear. This study investigated the prevalence and impact of CF on the outcomes of patients with AMI. All US adult (≥18 years) hospitalizations for AMI from January 2010 to November 2019 were identified using the Nationwide Readmissions Database. Patients were stratified by readmission at an index or nonindex center. Multivariable models were developed to evaluate factors associated with CF, and independent associations with mortality, complications, and resource utilization. A total of 413,819 patients with AMI requiring nonelective readmission within 30 days of discharge were included for analysis. Of these, 25.4% (n = 104,966) experienced CF. The incidence of CF increased from 2010 to 2019 (nptrend <0.001). After adjustment, patients insured by Medicaid faced higher odds of nonindex readmission. CF was associated with in-hospital mortality (adjusted odds ratio [AOR] 1.09, 95% confidence interval [CI] 1.01 to 1.18), and cardiac (AOR 1.12, 95% CI 1.03 to 1.22), respiratory (AOR 1.14, 95% CI 1.12 to 1.26), and infectious complications (AOR 1.14, 95% CI 1.07 to 1.22). Further, CF was linked to increased odds of nonhome discharge (AOR 1.18, 95% CI 1.11 to 1.24) and an additional ∼$5,000 in per-patient hospitalization costs (95% CI 4,260 to 5,100). Approximately 25% of AMI patients experienced CF, which was independently associated with excess mortality, complications, and expenditures. Given the growing national burden of cardiovascular disease, new efforts are needed to mitigate the significant clinical and financial implications of nonindex readmissions and improve value-based healthcare.

Association of frailty with outcomes of resection for colonic volvulus: A national analysis.

BACKGROUND: With limited national studies available, we characterized the association of frailty with outcomes of surgical resection for colonic volvulus. METHODS: Adults with sigmoid or cecal volvulus undergoing non-elective colectomy were identified in the 2010-2019 Nationwide Readmissions Database. Frailty was identified using the Johns Hopkins indicator which utilizes administrative codes. Multivariable models were developed to examine the association of frailty with in-hospital mortality, perioperative complications, stoma use, length of stay, hospitalization costs, non-home discharge, and 30-day non-elective readmissions. RESULTS: An estimated 66,767 patients underwent resection for colonic volvulus (Sigmoid: 39.6%; Cecal: 60.4%). Using the Johns Hopkins indicator, 30.3% of patients with sigmoid volvulus and 15.9% of those with cecal volvulus were considered frail. After adjustment, frail patients had higher risk of mortality compared to non-frail in both sigmoid (10.6% [95% CI 9.47-11.7] vs 5.7% [95% CI 5.2-6.2]) and cecal (10.4% [95% CI 9.2-11.6] vs 3.5% [95% CI 3.2-3.8]) volvulus cohorts. Frailty was associated with greater odds of acute venous thromboembolism occurrences (Sigmoid: AOR 1.50 [95% CI 1.18-1.94]; Cecal: AOR 2.0 [95% CI 1.50-2.72]), colostomy formation (Sigmoid: AOR 1.73 [95% CI 1.57-1.91]; Cecal: AOR 1.48 [95% CI 1.10-2.00]), non-home discharge (Sigmoid: AOR 1.97 [95% CI 1.77-2.20]; Cecal: AOR 2.56 [95% CI 2.27-2.89]), and 30-day readmission (Sigmoid: AOR 1.15 [95% CI 1.01-1.30]; Cecal: AOR 1.26 [95% CI 1.10-1.45]). Frailty was associated with incremental increase in length of stay (Sigmoid: +3.4 days [95% CI 2.8-3.9]; Cecal: +3.8 days [95% CI 3.3-4.4]) and costs (Sigmoid: +$7.5k [95% CI 5.9-9.1]; Cecal: +$12.1k [95% CI 10.1-14.1]). CONCLUSION: Frailty, measured using a simplified administrative tool, is associated with significantly worse clinical and financial outcomes following non-elective resections for colonic volvulus. Standard assessment of frailty may aid risk-stratification, better inform shared-decision making, and guide healthcare teams in targeted resource allocation in this vulnerable patient population.
