An assessment of treatment, transport, and refusal incidence in a National EMS's routine work during COVID-19.

BACKGROUND: COVID-19 created lifestyle changes, and induced a fear of contagion affecting people's decisions regarding seeking medical assistance. Concern surrounding contagion and the pandemic has been found to affect the number and type of medical emergencies to which Emergency Medical Services (EMS) have responded. AIM: To identify, categorize, and analyze Magen David Adom (MDA), Israel's national EMS, pre-hospital activities including patients' refusal to hospital transport, during the COVID-19 pandemic crises. METHODS: A comparative before and after design study of MDA incidents during March/April 2019 and March/April 2020. Medical type, frequency, demographic, location, and transport refusal proportions and outcomes were analyzed. RESULTS: A decrease of 2.6% in the total volume of incidents was observed during March and April 2020 compared with the equivalent period in 2019. This contrasted with the retrospective trend of annually increase observed through 2016-2019. Medical categories showing increase in 2020 were infectious disease, cardiac arrest, psychiatric, and labor and deliveries, with out-of-hospital deliveries increasing by 14%. Decreases in 2020 were seen in neurology and trauma, with trauma incidents occurring at home showing an 8.6% increase. Patients' refusal to transport rose from 13.4% in 2019 to 19.9% in 2020. Cases of refusals followed by death within 8 days were more prevalent in 2020. CONCLUSION: EMS must be prepared for changes in patients' behavior due to COVID concerns. Targeting populations at risk for refraining or refusing hospital transport and implementing diverse models of EMS, especially during pandemic times, will allow EMS to assist patients safely, either by reducing truly unnecessary ED visits minimizing contagion or by increasing hospital transports for patients in urgent or emergent conditions.

Impact of dispatcher assisted CPR on ROSC rates: A National Cohort Study.

INTRODUCTION: Out of hospital cardiac arrest (OHCA) is a leading cause of mortality. Bystander CPR is associated with increased OHCA survival rates. Dispatcher assisted CPR (DA-CPR) increases rates of bystander CPR, shockable rhythm prevalence, and improves ROSC rates. The aim of this article was to quantify and qualify DA-CPR (acceptance/rejection), ROSC, shockable rhythms, and associations between factors as seen in MDA, Israel, during 2018. METHODS: All 2018 OHCA incidents in Israel's national EMS database were studied retrospectively. We identified rates and reasons for DA-CPR acceptance or rejection. Reasons DA-CPR was rejected/non-feasible by caller were categorized into 5 groups. ROSC was the primary outcome. We created two study groups: 1) No DA-CPR (n = 542). 2) DA-CPR & team CPR (n = 1768). RESULTS: DA-CPR was accepted by caller 76.5% of incidents. In group 1, ROSC rates were significantly lower compared to patients in group 2 (12.4% vs. 21.3% p < .001). Group 1 had 12.4% shockable rhythms vs. 17.1% in group 2 (DA-CPR and team CPR). Of the total 369 shockable cases, 42.3% (156) achieved ROSC, in the non-shockable rhythms only 14.8% achieved ROSC. CONCLUSIONS: OHCA victims receiving dispatcher assisted bystander CPR have higher rates of ROSC and more prevalence of shockable rhythms. MDA dispatchers offer DA-CPR and it is accepted 76.5% of the time. MDA patients receiving DA-CPR had higher ROSC rates and more shockable rhythms. MDA's age demographic is high, possibly affecting ROSC and shockable rhythm rates.

Identifying and minimizing abuse of emergency call center services through technology.

BACKGROUND: To identify and minimize unnecessary calls to emergency numbers and to assess the effectiveness of call-tracking technology in addressing the problem. METHODS: A retrospective, interventional study was conducted of all emergency calls made to Magen David Adom (MDA), Israel's national Emergency Medicine Service (EMS) during years 2012-2016. In 2015 a tiered technological intervention was developed and implemented by MDA. The call-tracking technology self-identified harassment calls by call duration and frequency. The system automatically diverted harassing calls to a non-emergency number system in order not to lose any call. The rates of harassment calls were analyzed by shift, region, and season. Trends were compared before and after intervention. RESULTS: During the years 2012-2016, 53,527 shifts took place, and 8.2% (4277) of shifts identified as receiving incoming harassment calls. The evening shift (11.5%), the Jerusalem region (16.9%), and the summer season (9.6%) were most prone to harassment calls. After implementing an intervention using specialized call-tracking technology, the prevalence of harassment calls decreased significantly (from 10.9% to 2.9% p < .001). The Jerusalem region showed the greatest decrease of 92% (from 26.5%-2.0% p < .001). CONCLUSIONS: MDA's call tracking technology has been shown to identify and minimize harassment calls and can be implemented by emergency organizations to reduce abuse of emergency call services.
