Not only COVID-19 disease impacts ambulance emergency demands but also lockdowns and quarantines.

BACKGROUND: The pandemic has impacted both patients infected by the SARS-CoV-2 virus and patients who seek emergency assistance due to other health issues. Changes in emergency demands are expected to have occurred during the pandemic, the objective of this investigation is to characterize the changes in ambulance emergency demands during the first year of the COVID-19 pandemic in the Vaud State of Switzerland. The goal of this research is to identify the collateral effects of the COVID-19 pandemic on emergency demands. To do so, this study quantifies the differences in health issues, level of severity, and patients' sociodemographic characteristics (age, location, gender) prior to and during the outbreak. METHOD: This is a retrospective, descriptive and comparative statistical analysis of all ambulance emergency missions from 2018 to 2020 (n = 107,150) in the State of Vaud in Switzerland. Variables analyzed were the number of ambulance missions, patient age and gender, health issues, severity (NACA scores), number of non-transports, mission times and locations. Variables were compared between prepandemic and pandemic situations across years and months. Comparative analysis used bivariate analysis, χ2 test, Student's t test, and Mann‒Whitney U test. RESULTS: The pandemic has had two major impacts on the population's emergency demands. The first appears to be due to COVID-19, with an increase in respiratory distress cases that doubled in November 2020. The second relates to the implementation of lockdown and quarantine measures for the population and the closures of restaurants and bars. These might explain the decrease in both the number of traumas and intoxications, reaching more than 25% and 28%, respectively. An increase in prehospital emergency demands by the older population, which accounted for 53% of all demands in 2020, is measured. CONCLUSION: Collateral effects occurred during 2020 and were not only due to the pandemic but also due to protective measures deployed relative to the population. This work suggests that more targeted reflections and interventions concerning the most vulnerable group, the population of people 65 and older, should be of high priority. Gaining generalizable knowledge from the COVID-19 pandemic in prehospital settings is critical for the management of future pandemics or other unexpected disasters.

[Introduction of emergency paramedic investigators in the context of the COVID-19 pandemic in the Berlin emergency medical service]. / Einführung von NotSan-Erkundern im Rahmen der COVID-19-Pandemie in der Berliner Notfallrettung.

BACKGROUND: It has been shown throughout the COVID-19 pandemic that the condition of a number of patients deteriorates acutely when not monitored. This is set against an increased demand for emergency medical services and the resulting scarcity of resources, which makes it necessary to prioritise inpatient treatment or ensure that patients are provided with appropriate outpatient care. In this context, the Berlin Fire Department has introduced emergency paramedic investigators (NotSan-Erkunder) as an additional operating resource. METHODOLOGY: We assessed all operations from 28.03.2020 to 28.04.2020 during which Emergency Paramedic Investigators of the Berlin emergency services were deployed. A total of 341 operations were included from the 31 days. Alongside data from the dispatch system, all operational documentation was assessed. RESULTS: In 57% of cases, mNACA II patients (outpatient treatment) were identified, in 42% of cases, mNACA III patients (inpatient treatment) were identified, and in 1% of cases, mNACA IV (imminent danger to life) patients were identified. In 51% of cases, the emergency services transported the patient to a hospital, and in 49%, alternative care measures were employed. These included referral to a local physician in 28% of cases. In 11% of cases, patients were referred to on-call services of the Association of Statutory Health Insurance Physicians (KV in German). In 4% of cases, the Berlin Fire Department emergency dispatch center deployed a physician of the KV (KV-ARE investigator). DISCUSSION: The results show that additional operational resources serve an important function during a pandemic with regards to an initial assessment and pilot function. This can help relieve not only the emergency services but also the medical facilities responsible for providing further care. The standardised dispatch enquiry enables the linking with the appropriate codes from the low-priority operational spectrum and support by a Tele-emergency physician lends additional professional competency to the emergency paramedics.
