Suspected Labour as a Reason for Emergency Medical Services Team Interventions in Poland-A Retrospective Analysis.

The purpose of this study was to present the characteristics of Emergency Medical Services (EMS) team responses to calls regarding suspected labour in out-of-hospital settings in Poland. We performed a retrospective analysis of EMS team interventions in cases of suspected onset of labour outside a hospital setting. The analysis included 12,816 EMS team responses to calls regarding women in suspected labour in the period between January 2018 and December 2019. The mean age of the patients studied was 28.24 years (SD = 6.47). The majority of patients were at term (76.36%) and in their second pregnancy (29.96%). EMS teams were most often dispatched in the summer (25.95%) and in urban areas (63.26%). Most EMS teams were basic (68.99%) and interventions most often took place between 19:00 and 06:59 (63.14%). Significant differences were observed between preterm and term pregnant women attended by EMS teams in terms of variables such as the age of the patient, number of previous labours, history of miscarriage, presence of vaginal bleeding, time of year, location of call, type and composition of EMS team dispatched, urgency code and time of call, duration of intervention, selected emergency medical procedures performed and test results.
