Active shooter

PURPOSE OF REVIEW: There is widespread use of emergency preparedness drills in public K-12 schools across the US, but considerable variability exists in the types of protocols used and how these practices are conducted. This review examines research into both "lockdown drills" and "active shooter drills" as it relates to their impact on participants across different outcomes and evaluations of their procedural integrity. RECENT FINDINGS: A number of studies on lockdown drills yielded largely consistent findings about their impacts, whereas findings related to the effects of active shooter drills are less uniform...

PURPOSE: To analyse the reliability of ultrasound-guided measurement of the cartilage thickness at the medial femoral condyle in athletically active children and adolescents before and after mechanical load in relation to age, sex and type of sport. METHODS: Three successive measurements were performed in 157 participants (median/min-max age: 13.1/6.0-18.0 years, 106 males) before and after mechanical load by squats at the same site of the medial femoral condyle by defined transducer positioning...

Esports research lacks game-based metrics platforms appropriate for adequately capturing esports performance. The aim of this pilot study was to assess the reliability of the KovaaK's first-person shooter (FPS) aim trainer as a metrics platform for assessing shooting proficiency in esports players. Ten FPS esports players completed two identical experimental trials (T) separated by three to five days. Each trial included four rounds (R) of testing, evaluating four shooting tasks: Micro Flicking, Macro Flicking, Strafe Tracking, and Wall Peeking...

BACKGROUND: Mass school shootings have created fear in the American public. The results of this fear have been the hardening of schools, lockdowns, and active shooter drills, yet the mass shootings have not ended. The goal of this study was to analyze the mental health awareness of K-12 public schools teachers in Texas with a goal to identify the connections between mental health awareness and school safety. METHODS: Data were used from an archival database of K-12 teacher responses in the 2020 Texas Educators' Needs Assessment Regarding School Safety and Victims Services to assess the current state of student mental health concerns and the connection of these concerns to school safety...

BACKGROUND: The Ministry of Defence Police recognised the requirement to develop a Physical Employment Standard (PES) for the Authorised Firearms Officer -Counter Terrorism (AFO-CT) role profile. OBJECTIVE: The purpose of this study was to conduct a job task analysis to identify the most critical and physically demanding tasks performed by AFO-CT personnel. METHODS: A focus group and online survey were undertaken to identify a list of job tasks...

Mass casualty incidents (MCIs) are on the rise in the USA, and hemorrhage is the leading cause of preventable death in trauma. The need for rapid access to life-saving blood and blood products is essential for preventing death due to hemorrhage. It is well established that most major cities in the USA are underprepared to meet blood transfusion requirements in the event of an MCI. The South Texas Whole Blood Consortium sought to rectify this and vowed to be prepared to provide low-titer type O-positive whole blood (LTOWB) and blood components to the people who need it, where and when they need it...

Lockdown drill practice is part of the "new normal" in schools for young children with autism spectrum disorder (ASD) and educational practitioners in K-12 schools across the United States. These drills place a tremendous amount of responsibility on practitioners (i.e., teachers, paraprofessionals) that is beyond the scope of their training and typical requirements of their position in the classroom. Lockdown drills also require young children with ASD to engage in actions that are inherently hard for most young children but could be especially difficult for children with ASD who need individualized support to develop the executive function and self-regulation skills to participate in drills successfully...

Participation in a virtual reality based active shooter training drill (VR-ASD) has been shown to increase biomarkers of stress; however, the impact of caffeine consumption on this response has not been studied. Caffeine ingestion has been shown to have favorable effects on physical and cognitive performance among athletic and tactical occupations alike. This study examined the impact of caffeine ingestion on subjective and physiological markers of stress in response to a mental stress task (MST) which involved participation in a VR-ASD and cognitive challenge consisting of mental arithmetic and a Stroop challenge...

Gun violence is a principal cause of premature death in America. It has been suggested that solutions to gun violence may be found using a public health approach, which is broader than dealing with the problem via law enforcement alone. A component of a public health approach to gun violence is the implementation of policies or laws. Unfortunately, there is a serious gap in our understanding of how street-level police officers view proposed or existing firearms legislation. This is an important omission, because it is line-level personnel who are tasked with enforcing these policies within highly discretionary contexts...

BACKGROUND: Active shooter events are horrific, unfortunate realities in American hospitals. Protecting patients and staff in an active shooter event is made more difficult in the cases of critically ill and otherwise immobile patients. Previous work has proposed theoretical mitigation strategies for active shooter events. This study assesses American hospitals' current, active preparedness plans. METHODS: This is a survey-based study with questionnaires distributed to leaders in American healthcare...

INTRODUCTION: There are established protocols for staged return to physical activity in sport and military settings following concussion. Currently, there is no evidence-based staged return to shooting protocol in use by the U.S. military despite the unique challenges and stresses shooting places on the vestibular-ocular and cognitive systems often disrupted by a concussion. The primary purpose of this scoping review was to summarize available evidence and current practices on return to shooting post-concussion, with the goal of optimizing an evidence-based return to shooting protocol for military service members...

INTRODUCTION: Video games require precise motor skills, quick reaction times, and cognitive engagement. The tremendous growth of the electronic (e)-gaming industry has increased the demands for cognitive supplements (e.g., nootropics) to help e-athletes gain a competitive edge. The primary aim of this study was to evaluate the effects of combined caffeine + TeaCrine + Dynamine measures of neurophysiological and first-person shooter game performance in e-gamers. METHODS: Using a randomized double-blinded, crossover design, we assessed the effects of an acute, single-dose treatment of caffeine (200 mg) vs...

The purpose of the present study was to examine differences in kinematic characteristics between (a) proficient and non-proficient two-point and three-point shooters, (b) made and missed two-point and three-point shots within a proficient group of shooters, and (c) shots attempted from two-point and three-point shooting distances. Eighteen recreationally active females with previous basketball playing experience attempted 10 two-point (5.10 m) and 10 three-point shots (6.32 m) while facing directly to the basket...

Tactical occupations regularly encounter life-threatening situations while on duty. Although these occupations are often trained to utilize slow breathing (SB) during intense stress, there is no evidence supporting the effects on markers of stress in response to a virtual reality active shooter training drill (VR-ASD). The purpose of the study was to determine the impact of acute SB on biomarkers of stress in response to a VR-ASD. Seventy-nine (n = 79) subjects performed either slow breathing method 1 (SB1), slow breathing method 2 (SB2), or normal breathing (control) for five minutes, both pre- and post-VR-ASD...

Mass shootings are horrific events that annually take scores of innocent lives in the United States. Federal, state, and local governments as well as educational, religious, and private-sector organizations propose and enact polices and strategies to protect people from and during active shooter situations. A probabilistic risk assessment of a mass shooting for a specific organization, jurisdiction, or location can be the first step toward evaluating the effectiveness of risk mitigation strategies and determining which strategies might be most appropriate for a location...

The winning game outcome in basketball is partially contingent on the team's ability to secure and make more free-throw shooting attempts, especially close to the end of the game. Thus, the purpose of the present study was to perform a comprehensive biomechanical analysis of the free-throw shooting motion to examine differences between (a) proficient (≥70%) and non-proficient shooters (<70%) and (b) made and missed free-throw shoots within the proficient group of shooters. Thirty-four recreationally active males with previous basketball playing experience attempted ten consecutive free-throw shots (4...

OBJECTIVE: US trauma centers (TCs) must remain prepared for mass casualty incidents (MCIs). However, trauma surgeons may lack formal MCI training. The recent COVID-19 pandemic drove multiple patient surges, overloaded Emergency Medical Services (EMS) agencies, and stressed TCs. This survey assessed trauma surgeons' MCI training, experience, and system and personal preparedness before the pandemic compared with the pandemic's third year. METHODS: Survey invitations were emailed to all 1544 members of the American Association for the Surgery of Trauma in 2019, and then resent in 2022 to 1575 members with additional questions regarding the pandemic...

BACKGROUND: An active shooter in a hospital is an emergency extraordinaire. We report a single institution's response to the largest active shooter mass casualty event in American History. METHODS: Review of notification, flow of prioritized patients, and key elements of the day's dynamic after a hospital attack by a lone gunman was commenced. The review includes outcomes on seven victims and assailants. RESULTS: "Code Silver" announced: open display of a weapon...

Given the numerous active shooter and hostile events (ASHE) happening each year, it is important for fire and emergency medical service (EMS) agencies to share the lessons learned from such events. This paper discusses the elements needed for an effective fire and EMS response, beginning with the unified command/collaboration approach with law enforcement that allows for the proper management of such events. The article further defines the command and control elements, as well as the proper staffing and actions needed from fire and EMS to remove, triage, treat and transport victims effectively...

A steady increase in shooting practices is observed worldwide. Potential lead exposure at shooting ranges poses a risk to their employees and users, which is not widely reported outside of the USA, especially in Poland. Exposure to lead results from the use of bullets containing lead and the main route of exposure to this metal at shooting ranges is inhalation, i.e., during shooting or cleaning. The aim of this study was to assess lead exposure of employees and users in selected indoor shooting ranges in central Poland...
