Article Abstract
Background And Objectives: Firearm-related penetrating traumatic brain injury (pTBI) carries a high mortality risk and grim prognosis. This study aimed to quantify interhospital variation in operative intervention for this patient population and assess whether cranial surgery tendency is associated with inpatient mortality.
Methods: We conducted a retrospective cohort study using the American College of Surgeons Trauma Quality Improvement Program (TQIP) data set to identify adult patients presenting with firearm-related pTBI. Risk-adjusted hierarchical regression evaluated associations with cranial surgery. Hospitals were stratified into quartiles based on surgical tendency (lowest, quartile 1; highest, quartile 4 [Q4]). Propensity score matching was performed across quartiles, and a multivariable regression model was constructed to investigate associations between hospital quartile and inpatient mortality. Effect modification by pupillary reactivity was tested.
Results: Cranial surgery rates for 4895 patients (median age, 31 years) varied widely across 309 hospitals (0%-71%; median, 21%; median odds ratio, 1.33). After matching, treatment at Q4 hospitals was associated with significantly reduced odds of mortality compared with treatment at quartile 1 hospitals (odds ratio, 0.61; 95% CI, 0.47-0.78). Patients presenting with one (interaction P = .03) or both (interaction P = .03) unreactive pupils experienced amplified survival benefits from treatment at Q4 hospitals.
Conclusion: Substantial interhospital variation exists in operative intervention for firearm-related pTBI. Hospitals with higher surgical tendency were associated with improved survival, and this effect was amplified for patients presenting with unreactive pupils. These findings suggest a need to standardize operative decision-making for patients with firearm-related pTBI, aligning with ongoing efforts by organizations such as the Brain Trauma Foundation.

Background: The COVID-19 pandemic disrupted healthcare systems globally, raising concerns about delayed cancer diagnosis and treatment. In France, transurethral resection of bladder tumors (TURBT) was prioritized in national urology guidelines to ensure the timely management of urothelial carcinoma. This study aimed to assess the impact of care reorganization on tumor staging, recurrence, palliative care, and mortality in bladder cancer patients from the pre-pandemic through late-pandemic periods.

Aims: Postoperative periprosthetic femoral fractures (POPFFs) following hip arthroplasty pose complex challenges, with differences in management and outcomes across healthcare facilities. However, there is limited published literature on such variability to inform improvement initiatives. This study aims to quantify the between-hospital variations in surgical management and short-term outcomes.

Background: Failure to rescue (FTR), defined as death after a surgical complication, is strongly impacted by systems-level care processes. The purpose of this study was to optimize the definition of FTR by developing the methodology for, and evaluating the subsequent impact of, adding complications to the Society of Thoracic Surgeons (STS) definition.
Methods: Patients undergoing coronary artery bypass grafting and/or valve operations from 2011-2024 in Michigan were included.
Investigating Tertiary X-radiation Exposure in C-arm Units: Risks and Mitigation.

Fluoroscopic C-arm units are used routinely in surgical procedures, but they pose potential radiation hazards, particularly in terms of scatter and tertiary exposure to healthcare providers, which can lead to long-term health effects. This study investigates the level of scatter radiation emitted by the C-arm during Dynamic Hip Screw (DHS) surgery across four general hospitals. A water phantom was placed in the center of the operating table, simulating an average patient.

Background: Cardiogenic shock (CS) is a leading cause of mortality following acute myocardial infarction (AMI). Some patients may require intra-aortic balloon pump (IABP) or percutaneous ventricular assist device (PVAD) placement; however, there is a paucity of standardised algorithms to guide the deployment of each device. The present study evaluated interhospital variation in the use of IABP and PVAD for AMI CS and identified institutional factors associated with hospital-level device preference.
