Workplace violence among Asian emergency medical services (EMS) has rarely been examined. A cross-sectional, mainly descriptive study using a standardized, paper-based, self-reported questionnaire survey was conducted between August and October 2018 among emergency medical technicians (EMTs) in the Tainan City Fire Bureau, Taiwan. A total of 152 EMT-paramedics responded to the questionnaire survey, constituting an overall response rate of 96.2%. The participants were predominantly male (96.1%), college-educated (4-year bachelor’s degree) (49.3%), and middle-aged (35–44 years old) (63.8%). Among them, 113 (74.3%) and 75 (49.3%) participants had experienced verbal and physical assaults at work, respectively. Only 12 (7.9%) participants were familiar with relevant regulations or codes. The assaults predominantly occurred during evening shifts (16:00–24:00) and at the scene of the emergency. The most predominant violence perpetrators included patients, patients’ families, or patients’ friends. Nearly 10% of participants had experienced verbal assaults from hospital personnel. EMTs who encountered workplace violence rarely completed a paper report, filed for a lawsuit, or sought a psychiatric consultation. Fifty-eight (38.2%) and 16 (10.5%) participants were victims of frequent (at least once every 3 months) verbal and physical forms of violence, respectively; however, no statistically significant association was observed in terms of EMT gender, age, working years, education level, or the number of EMS deployments per month. The prevalence of workplace violence among Asian EMS is considerable and is comparable to that in Western countries. Strategies to prevent workplace violence should be tailored to local practice and effectively implemented.

BackgroundResuscitation efforts for traumatic patients with out-of-hospital cardiac arrest (OHCA) are not always futile. Dispatcher-assisted cardiopulmonary resuscitation (DA-CPR) during emergency calls could increase the rate of bystander cardiopulmonary resuscitation (CPR) and thus may enhance survival and neurologic outcomes of non-traumatic OHCA. This study aimed to examine the effectiveness of DA-CPR for traumatic OHCA.MethodsA retrospective cohort study was conducted using an Utstein-style population database with data from January 1, 2014, to December 31, 2016, in Tainan City, Taiwan. Voice recordings of emergency calls were retrospectively retrieved and reviewed. The primary outcome was an achievement of sustained (≥2 h) return of spontaneous circulation (ROSC); the secondary outcomes were prehospital ROSC, ever ROSC, survival at discharge and favourable neurologic status at discharge. Statistical significance was set at a p-value of less than 0.05.ResultsA total of 4526 OHCA cases were enrolled. Traumatic OHCA cases (n = 560, 12.4%), compared to medical OHCA cases (n = 3966, 87.6%), were less likely to have bystander CPR (10.7% vs. 31.7%, p < 0.001) and initially shockable rhythms (7.1% vs. 12.5%, p < 0.001). Regarding DA-CPR performance, traumatic OHCA cases were less likely to have dispatcher recognition of cardiac arrest (6.3% vs. 42.0%, p < 0.001), dispatcher initiation of bystander CPR (5.4% vs. 37.6%, p < 0.001), or any dispatcher delivery of CPR instructions (2.7% vs. 20.3%, p < 0.001). Stepwise logistic regression analysis showed that witnessed cardiac arrests (aOR 1.70, 95% CI 1.10–2.62; p = 0.017) and transportation to level 1 centers (aOR 1.99, 95% CI 1.27–3.13; p = 0.003) were significantly associated with achievement of sustained ROSC in traumatic OHCA cases, while DA-CPR-related variables were not (All p > 0.05).ConclusionsDA-CPR was not associated with better outcomes for traumatic OHCA in achieving a sustained ROSC. The DA-CPR program for traumatic OHCAs needs further studies to validate its effectiveness and practicability, especially in the communities where rules for the termination of resuscitation in prehospital settings do not exist.

The ATA-associated fatality rate in Taiwan was high, and all fatalities were associated with motorcycles. ATAs in a highly motorcycle-populated area may require further investigation. An ambulance traffic accident reporting system should be built to provide EMS policy guidance for ATA reduction and outcome improvements.

Paramedics can provide advanced life support (ALS) for patients with out-of-hospital cardiac arrest (OHCA). However, the impact of emergency medical technician (EMT) configuration on their outcomes remains debated. A three-year cohort study consisted of non-traumatic OHCA adults transported by ALS teams was retrospectively conducted in Tainan City using an Utstein-style population database. The EMT-paramedic (EMT-P) ratio was defined as the EMT-P proportion out of all on-scene EMTs. Among the 1357 eligible cases, the median (interquartile range) number of on-scene EMTs and the EMT-P ratio were 2 (2–2) persons and 50% (50–100%), respectively. The multivariate analysis identified five independent predictors of sustained return of spontaneous circulation (ROSC): younger adults, witnessed cardiac arrest, prehospital ROSC, prehospital defibrillation, and comorbid diabetes mellitus. After adjustment, every 10% increase in the EMT-P ratio was on average associated with an 8% increased chance (adjusted odds ratio [aOR], 1.08; p < 0.01) of sustained ROSC and a 12% increase change (aOR, 1.12; p = 0.048) of favorable neurologic status at discharge. However, increased number of on-scene EMTs was not linked to better outcomes. For nontraumatic OHCA adults, an increase in the on-scene EMT-P ratio resulted in a higher proportion of improved patient outcomes.
