摘要

Background

Pre-hospital care plays a crucial role in the management and control of emergency patients and medical emergencies. The faster and more accurate the performance of medical emergency bases in terms of time and response, the lower the mortality rate, patient injuries, and burden on hospitals. This study aimed to evaluate the temporal indicators of pre-hospital emergencies in operational bases in Qazvin, Iran.

Methods

This is a cross-sectional study. The study population included all pre-hospital emergency missions recorded in 2021 at the pre-hospital emergency centers in the city of Qazvin. The inclusion criteria for the study were cases with completely and accurately documented information. After excluding missions that did not meet the inclusion criteria, a total of 7621 missions remained. A sample of 366 missions was randomly selected to initiate the study, and the required information, including demographic population, geographical service provision, service performance, and temporal indicators, was extracted from the ambulance base forms. Independent t-tests and ANOVA tests with a significance level of 0.05 were used to establish relationships between variables and compare temporal indicators in the two selected periods.

Results

The average delay time (1.833 min), response time (13.746 min), scene time (17.759 min), total time intervals (52.657 min), hospital transfer time (21.036 min), and total mission time (89.091 min) were obtained. The highest number of missions occurred in the summer season (27%), while the lowest number of missions (4.23%) occurred in the spring season. A statistical comparison between the first and second six-month periods of the year did not reveal any significant differences (p > 0.05).

Conclusion

The research findings indicate that the delay time and scene time indicators were desirable and within national standards. However, the response time indicator in this study exceeded the national standard and did not meet the acceptable level.
