Importance Hospital-based shootings represent an extreme form of workplace violence, with notable consequences for staff, patients, and visitors. Despite growing concern, these events remain poorly understood. Objective To categorize hospital-based shootings from 2012 to 2024 and incorporate prior published events between 2000 and 2011 to examine trends in shootings over a 25-year span. Evidence Review Events in this systematic review of acute care hospital–based shootings in the US from January 1, 2012, through December 31, 2024, with subgroup analysis of previously published data trending shootings over 25 years (January 1, 2000, through December 31, 2024), were identified using EBSCO Regional Business News, ProQuest US Newsstream Collection, Gun Violence Archive, and Google News Search. Selected shooting events involved at least 1 injured person (a nonperpetrator or perpetrator) that occurred within or on the immediate property of the hospital. Findings A total of 327 news articles of unique hospital-based shooting events (5.2 per year per 1000 hospitals) were included from a review of 6658 articles, spanning 47 US states (94.0%). There was an overall incidence of 25.2 hospital-based shootings per year. Between 2012 and 2024, shootings increased by a mean (SD) of 1.7 (0.5) events per year, from 14 to 34 events (8.4% increase per year). Large hospitals accounted for the highest rate of shootings (258.1 events per 1000 hospitals). Events primarily occurred in urban settings (314 [96.0%]), and 161 (49.2%) occurred in the US South. Nearly one-third (105 [32.1%]) were potentially preventable by weapons screening. From 2000 to 2024, shootings increased by a mean (SD) of 1.1 (0.2) events per year, from 6 to 34 events (6.4% increase per year). A positive correlation was found in annual firearm fatalities in hospital settings and US firearms fatalities overall between 2012 and 2023 ( r = 0.42). Conclusions and Relevance This systematic review found that hospital-based shootings in the US have increased steadily over the past 25 years, representing an intersection between broader national trends in workplace and firearm violence. Large hospitals, those in the US South, and hospitals in urban communities are particularly at-risk settings. These findings underscore the need for hospital-specific prevention strategies, including consideration of weapons screening technology, alongside broader societal efforts to address rising firearm violence.
Mortality in the Sepsis-3 Era: A Systematic Review of Multicenter Randomized Controlled Trials
This systematic review examined multicenter randomized controlled trials (RCTs) conducted during the Sepsis-3 era that evaluated pharmaceutical and mechanistic interventions in adult patients with sepsis or septic shock, with a focus on identifying interventions that demonstrated mortality benefit. A comprehensive search was performed across Ovid MEDLINE, Embase, Cochrane Central, ClinicalTrials.gov, WHO ICTRP, and Web of Science for trials published since 2016. Studies were included if they enrolled adult patients with sepsis or septic shock using Sepsis-3 criteria and reported mortality as either a primary or secondary outcome. Data were extracted by two independent reviewers and included trial design characteristics, funding source, randomization methods, and reported outcomes. Among the 31 eligible multicenter RCTs enrolling over 7,000 patients across 550 centers, only four trials showed a mortality benefit. These included three studies from China—two evaluating herbal anti-inflammatory compounds and one evaluating aminophylline—and one European study assessing corticosteroid therapy in vasopressor-dependent septic shock. The remaining 27 trials reported no mortality benefit, and substantial heterogeneity was observed in patient populations, sepsis definitions, and outcome reporting. Median mortality in control arms was 31.6% (IQR 24.1–45.5), and 35.4% (IQR 25.7–49.6) in intervention arms. These findings suggest that despite extensive efforts, most interventions have not reduced mortality in multicenter sepsis trials. Future research should focus on optimizing trial design, refining patient selection, and incorporating patient-centered outcomes beyond mortality.
The Clinical Impact of Mitral Gradient Post Transcatheter Edge‐To‐Edge Repair: A Systematic Review and Meta‐Analysis
ABSTRACTBackgroundMitral transcatheter edge‐to‐edge repair (TEER) is a minimally invasive therapy for severe mitral regurgitation (MR) in patients with high surgical risk. TEER results in a tissue bridge that decreases mitral valve area, potentially leading to elevated mean gradient. The clinical impact of elevated gradient on outcomes is unclear.MethodsThis systematic review and meta‐analysis was based on a comprehensive search of five databases. We included studies that evaluated post mitral TEER gradient on one of the following outcomes: all‐cause mortality, combined endpoints, symptoms, hospitalizations, and mitral valve re‐intervention. Meta‐analysis was conducted using the random‐effects model.ResultsOut of 6458 citations, 17 studies were included (2017−2024) reporting on 7748 patients. There was significant heterogeneity between studies related to the cutoff used to define elevated gradient, etiology of MR, and outcomes. Elevated mitral gradient post TEER (4, 4.5, 5 mmHg) was associated with worse combined endpoint (HR = 1.35, 95% CI 1.07−1.71; I2 64%), but not all‐cause mortality (HR = 1.25, 95% CI 0.97−1.59; I2 45%) or risk of hospitalization. For the combined endpoint, this association was mainly significant in patients who had mitral gradient assessed using discharge echocardiogram (HR = 1.39, 95% CI 1.07−1.81; I2 62%) for all patients and for those with degenerative MR.ConclusionDespite the heterogeneity between studies, the current analysis suggests that patients with elevated mitral gradient post TEER are at risk of worse clinical outcomes, particularly in patients who had mitral gradient assessed using discharge transthoracic echocardiogram.
