Background The COVID-19 pandemic resulted in many changes in pre-hospital emergency medical services (EMS), including wearing full-body protective suits and well-fitted face masks, which can influence time indices in the course of service delivery. The present study aimed to compare the time indices of pre-hospital EMS missions before and during the COVID-19 pandemic in Iran. Methods This descriptive cross-sectional study used census sampling to select 17,860 emergency calls that caused patient transfer to medical facilities from March 2018 to March 2021 and then examined the time indices of pre-hospital EMS missions during the COVID-19 pandemic. The data collection tool was a two-part checklist: patients' individual characteristics and pre-hospital EMS mission time indices. The data were further analyzed using the SPSS16 and independent samples t-test. Results Out of the patients transferred by the EMS, 11,773 cases (65.9%) were male and 6,087 (34.1%) were female. The most common reason for the emergency calls was accidents (28.0%). Moreover, response time (P < 0.001), on-scene time (P < 0.001), transfer time (P < 0.001), total run time (P < 0.001), and round trip time (P < 0.001) increased significantly during the COVID-19 pandemic. Conclusions We concluded that the EMS time indices elevated following the COVID-19 pandemic. Updating pre-hospital information management systems, ambulances and medical equipment, as well as holding training courses for pre-hospital EMS personnel could effectively enhance the time indices of pre-hospital EMS missions.

Background Pre-hospital emergency medicine (PHEM) personnel are at risk of developing psychological disorders during the Covid-19 pandemic. This study aimed to investigate depression, anxiety, and stress levels of the Iranian PHEM personnel during the Covid-19 pandemic. Methods This descriptive cross-sectional study was performed on 544 PHEM personnel chosen by purposive sampling in North Khorasan, Khorasan-Razavi, South Khorasan, Sistan-Baluchestan, and Kerman provinces in eastern Iran from August to September 2021. Data collection tools included a demographic information questionnaire and the standardized 21-item Depression, Anxiety, and Stress Scale (DASS-21). Data were analyzed in SPSS 16 using one-way analysis of variance and linear regression. Results The mean scores of depression, anxiety, and stress were 8.7 ± 9.2, 7.0 ± 7.8, and 11.6 ± 9.2, respectively. Depression, stress, and anxiety were more prevalent in the age group of 41-55 years, people with master’s and higher degrees, people with a history of underlying diseases, and people with over 10 years of work experience(p < 0.05). Depression and stress also showed a significant relationship with the type of employment. Stress alone was also significantly associated with working less than 35 hours a week and living separately from family(p < 0.05). Conclusions PHEM personnel suffer from significant levels of depression, anxiety, and stress during the Covid-19 pandemic. Therefore, in order to improve the mental condition, it is recommended that the work schedule and services provided to these people be designed in such a way that they have more time for rest and communication with their family members. The personnel should also have easier access to the expert team in the fields of counseling and psychiatry.
