Introduction: Since 2001, the world has encountered an increase in terrorist attacks on civilian targets, during which conventional as well as unconventional modalities are being used. Terrorist attacks put immediate strains on health care systems, whilst they may also directly threaten the safety of first responders, health care workers, and health care facilities.

Study objective: This scoping review aimed to systematically map the existing research on terrorist attacks targeting health care facilities, health care workers, and first responders, and to identify opportunities to improve future research and health care response to terrorist attacks.

Methods: A scoping review was performed according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) extension for scoping reviews. A systematic search for relevant literature was conducted through electronic databases including PubMed, Cochrane, and Embase. Inclusion and exclusion criteria were applied to check eligibility. Extracted data from the articles included the title, first author, year of publication, journal, study design, number of attacks, number of injured, number of fatalities, target type, and weapon modalities. Furthermore, methodological quality assessment was performed.

Results: The initial search within three major databases yielded 4,656 articles, including 2,777, 1,843, and 36 articles from PubMed, Embase, and Cochrane Library, respectively. Finally, 11 studies were included, which were all database reviews.

Conclusions: This scoping review included 11 studies focusing on terrorist attacks against health care facilities, health care workers, and first responders. Nearly all studies were exclusively based on the Global Terrorism Database (GTD). An increase of attacks on health care-related targets was consistently reported by all studies in this review, but there were significant discrepancies in reported outcomes. In order to improve counter-terrorism preparedness and the future protection of health care workers, counter-terrorism medicine (CTM) research may benefit from a more standardized and transparent approach to document and analyze terrorist attacks, as well as the inclusion of additional databases other than the GTD.

Background: Modern conflicts are characterized by wide-spread use of conventional explosive ordnance (EO), improvised explosive devices (IEDs), and other air-launched explosives. In contrast to advances in military medicine and high-income civilian trauma systems since the United States-led wars in Afghanistan and Iraq, the mortality rate among civilian EO casualties has not decreased in decades. Although humanitarian mine action (HMA) stakeholders have extensive presence and medical capabilities in EO-affected settings, coordination between HMA and health actors has not been leveraged systematically.

Methods: Data from a prior systematic review of emergency care interventions feasible within the context of HMA activities and low-resource health care systems were used to model mortality reduction among EO victims. Interventions were categorized using the World Health Organization (WHO) Emergency Care System Framework sites of "scene," "transport," and "facility." The cumulative impact of the interventions on EO-related mortality was estimated using pooled effect estimates and simulation modeling.

Results: The meta-analysis included 16 reports from 13 countries, representing 127,505 injured persons. Pooled effect estimates across subcategories of emergency care interventions were 0.42 for layperson transportation (95%CI, 0.24-0.74), 0.79 for prehospital notification systems (95%CI, 0.51-1.19), 0.52 for prehospital trauma care training courses (95%CI, 0.46-0.59), 0.67 for facility-based trauma care training courses (95%CI, 0.48-0.92), and 0.66 for facility-based trauma team organization and activation protocols (95%CI, 0.45-0.97). A 68% reduction in mortality (95%UI, 57%-79%) was observed when implementing the full set of interventions in a region with no prior implemented interventions.

Conclusion: Enhanced coordination between HMA and health actors to implement a structured set of emergency care interventions holds potential to significantly reduce preventable death among civilian EO casualties.

Background: The aim of this study was to analyze the prevalence of psychiatric symptoms in prehospital emergency care and the characteristics of this patient group as well as the association with deprivation in the district, self-assessment of health status, and the frequency of emergency calls due to or accompanied by psychiatric diagnoses.

Methods: A retrospective cross-sectional study descriptively and analytically evaluated all ground-based Emergency Medical Service and rescue service incidents dispatched by the Integrated Regional Control Center (IRLS) in the period from January 1, 2021 through December 31, 2021. In addition to the clinical parameters and the demographic data of the patients, the sociodemographic characteristics of the incident location at the district level, unemployment rate, net equivalent household income, and the proportion of single-person households, as well as personal assessment of mental health and overall well-being, were included in the study.

Results: A total of 68,345 deployment protocols were examined. Of these, 6.4% were emergency incidents due to or involving psychiatric diagnoses. Emergency physician (EP) involvement in these operations was 56.1%. RM Andersen's Behavioral Model of Health Services Use (1968) was used as a theoretical reference model for the description, analysis, and explanation of the use of health-related care. The analyses showed that interventions due to or involving psychiatric diagnoses without emergency doctor alerts were more frequent in urban districts with a high proportion of single-person households and a high net equivalized houshold income.

Conclusion: The accumulation in individual city districts and the factors identified by Andersen point to opportunities to target preventive measures to avoid emergencies involving psychiatric diagnoses in order to use limited resources efficiently.

Between January 29 and February 11, 2019, the Townsville region in Australia experienced a major flooding event. This study explored impacts on affected community pharmacies. Semi-structured phone interviews were conducted with six pharmacists who worked in affected Townsville community pharmacies during this flood. De-identified transcript data were analyzed using reflexive thematic analysis. The thematic analysis yielded six themes - "financial impact on pharmacy owners," "engagement with Local Disaster Coordination Center (LDCC) important," "workload pressures," "preparedness," "medication supply impacts," and "communication and collaboration." Financial impacts to owners included loss of property (two pharmacies were completely flooded), purchase or hire costs of generators when power was lost, and loss of revenue from complete or early closure of pharmacies and when patients could not pay or did not have a prescription and did not return to the pharmacy after the event. Engagement with the LDCC assisted pharmacy responsiveness. Medication supply issues were experienced by patients whose houses had flooded, or who had left their prescriptions with pharmacies that had flooded. Opioid Replacement Therapy (ORT) program patients were also impacted due to communication difficulties between them, their clinics, and their pharmacies. Increased customer numbers by those whose regular pharmacy was closed, reduced staff numbers, and austere working conditions increased workload pressures. Pharmacists collaborated to consolidate resources with those whose pharmacy had closed, working in pharmacies that were open. This research highlights a critical need for improved flood preparedness among Townsville pharmacists. Regardless, they collaborated to ensure there were minimal critical medication delays.

Introduction: Many factors influence the likelihood of bystander cardiopulmonary resuscitation (BCPR) after out-of-hospital cardiac arrest (OHCA), but gender disparities in prehospital care remain under-examined, particularly in relation to the bystander's connection to the patient.

Objective: The objective of this study was to evaluate the association between gender and the likelihood of receiving BCPR in OHCA. The primary outcome of the study was to examine differences in BCPR rates among men and women who experienced OHCA. The secondary outcome was to investigate whether bystanders were more likely to provide CPR based on their relationship to the victim, comparing "true" layperson CPR to CPR administered by family members or friends and how these rates differed between men and women.

Methods: This retrospective prehospital chart review included all encounters from a single urban Emergency Medical Services (EMS) agency with a cardiac arrest prior to EMS arrival from January 1, 2017 through June 30, 2022 (n = 701). For each encounter, the presence or absence of BCPR was recorded, along with the relation of the bystander to the patient. "True" BCPR was defined as CPR performed by a layperson unknown to the patient. Patients were excluded if they exhibited signs of obvious death, were physically inaccessible to bystanders, had CPR initiated by trained facility staff or police, had a do not resuscitate (DNR) order present on EMS arrival, received CPR but were not in cardiac arrest, or were younger than 18 years old (n = 174). Odds ratios (OR) with 95% confidence intervals (CI) were used to evaluate data, with statistical significance defined at P < .05.

Results: The study examined 701 cardiac arrest encounters: 250 female (35.7%) and 451 male (64.3%). Overall, men (n = 123; 27.3%) were more likely to receive BCPR than women (n = 48; 19.2%); OR = 1.58; 95%CI, 1.08-2.30; P = .02. Among those who received BCPR, women were significantly more likely to have received it from someone they knew (83.3% versus 65.9%; OR = 2.59; 95%CI, 1.11-6.04; P = .03) while men were more likely to receive "true" layperson BCPR.

Conclusions: This study identifies significant gender disparities in prehospital BCPR and highlights an association between the bystander's relationship to the patient and the likelihood of intervention.

Introduction: Conceptualizations of surge capacity are gaining traction in disaster preparedness and response, particularly in the context of critical and acute care during the pandemic as well as other disaster contexts. In most applications, the surge capacity domains describe the four types of assets required to ensure that surges in demand are addressed. Despite increasing interest and conceptual application, these constructs are yet to be considered or explored in relation to the profound resource scarcity and complex contexts of humanitarian health responses.

Objectives: The aim of this research is to explore surge capacity domain constructs in the novel context of scarce health resource allocation in humanitarian health care response settings.

Methods: This research was conducted according to an exploratory qualitative design. Clinicians and managers with relevant experiences were purposively recruited to include broad perspectives across humanitarian responses and clinical specialties. Interview transcripts were analyzed using a latent deductive pattern approach, using a deductive code book consisting of existing surge capacity domains to explore surge capacity constructs. Analysis of coded data for cross-cutting themes drove identification of new findings regarding surge capacity in the context of humanitarian health responses.

Results: Seventeen participants completed semi-structured interviews. In addition to demonstrating the relevance of existing surge capacity domains (staff, stuff, space, and systems; 4Ss), four new themes emerged: (1) sponsorship; (2) suitability; (3) security; and (4) supply. These four themes informed the conceptualization of surge capacity dimensions which must be satisfied for an asset to render a positive impact with relevance to all four surge capacity domains (4S² - cumulative 4S domains and the new dimensions).

Conclusions: Although existing surge capacity domains have proven relevant to humanitarian health care response settings, this research produced a revised conceptualization of surge capacity constructs specific to this context. The identification of four surge capacity dimensions supported the conception and development of the Scarce Health Resource Allocation in Humanitarian Response Settings (SHARE-HRS) 4S² model of surge capacity, thus offering a potential new tool to support humanitarian health response planning and evaluation.

Objective: This study explores the impact of heatwaves on emergency calls for assistance resulting in service attendance in the Australian state of Queensland for the period from January 1, 2010 through December 31, 2019. The study uses data from the Queensland Ambulance Service (QAS), a state-wide prehospital health system for emergency health care.

Methods: A retrospective case series using de-identified data from QAS explored spatial and demographic characteristics of patients attended by ambulance and the reason for attendance. All individuals for which there was an emergency call to "000" that resulted in ambulance attendance in Queensland across the ten years were captured. Demand for ambulance services during heatwave and non-heatwave periods were compared. Incidence rate ratio (IRR) and 95% confidence intervals (CI) were constructed exploring ambulance usage patterns during heatwaves and by rurality, climate zone, age groups, sex, and reasons for attendance.

Results: Compared with non-heatwave days, ambulance attendance across Queensland increased by 9.3% during heatwave days. The impact of heatwaves on ambulance demand differed by climate zone (high humidity summer with warm winter; hot dry summer with warm winter; warm humid summer with mild winter). Attendances related to heat exposure, dehydration, alcohol/drug use, and sepsis increased substantially during heatwaves.

Conclusion: Heatwaves are a driver of increased ambulance demand in Queensland. The data raise questions about climatic conditions and heat tolerance, and how future cascading and compounding heat disasters may influence work practices and demands on the ambulance service. Understanding the implications of heatwaves in the prehospital setting is important to inform community, service, and system preparedness.

For many researchers, the ethical approval process can appear confusing, overwhelming, or irrelevant. Common sources of confusion include knowing which types of ethics approvals are required, how to get the approval, and understanding the language surrounding the review process. This editorial discusses the importance of ethics in creating and reporting quality research and provides a practical guide to help navigate the ethical approval process.

Background: The European Resuscitation Council (ERC) establishes guidelines for cardiopulmonary resuscitation (CPR) under standard conditions and special circumstances but without specific instructions for nighttime situations with reduced visibility. The aim of this study was to evaluate the feasibility of performing CPR at night under two different conditions, in darkness with ambient light and with the additional illumination of a headlamp, as well as to determine the quality of the maneuver.

Methods: A crossover, randomized pilot study involving nineteen lifeguards was conducted, with each participant performing two five-minute CPR tests: complete darkness with headlamp and natural night environment at the beach without additional lighting. Both tests were conducted with a 30:2 ratio of chest compression (CC) to ventilations using mouth-to-pocket mask technique in the darkness of the night with a 30-minute break between them. Outcome measures included quality of CPR, number of CCs, mean depth of CCs, mean rate of CCs, and number of effective ventilations. Results were reported as the mean or median difference (MD) between the two groups with 95% confidence interval (CI) using techniques for paired data.

Results: There were no statistically significant differences between the two lighting conditions for the outcomes of CPR quality, mean depth of CCs, or number of effective ventilations. The number of CCs was lower when performed without the headlamp (MD: -8; 95%CI, -15 to 0). In addition, the mean rate of CCs was lower when performed without the headlamp (MD: -3; 95%CI, -5 to -1).

Conclusions: The rescuers performed CPR at night with good quality, both in darkness and with the illumination of a headlamp. The use of additional lighting with a headlamp does not appear to be essential for conducting resuscitation.
