Calls due to suicidal behaviour made to the prehospital, emergency department in Malaga: characteristics and associated factors

Background. Suicidal behaviour (fatal and non-fatal) has become a serious public health problem in many countries. The aim of the study was to describe the differential characteristics of emergency calls due to suicidal behaviour made to the Emergency Coordinating Centre (CCUE) in the province of Malaga, in comparison with calls due to physical or psychiatric problems. Methods. Retrospective observational study of the calls recorded in the database of the Public Company for Emergency Health during one year. Multivariate logistic regression analyses were carried out including age, gender and the following variables related with the demand: hours of the day, type of day (working days or bank holidays), months of the year and trimesters, number of resources mobilized and types of resolution. Results. The analyses were carried out on 163,331 calls, of which 1,380 calls were due to suicidal behaviour (0.8%), 9,951 for psychiatric reasons (6.1%) and 152,000 for physical reasons (93%). The emergency calls for suicidal behaviour were mainly made by females, between 31-60 years, in the evening and at night, and required transfer to hospital and more than one mobilized resource. Calls due to completed suicide were more frequently made by older men. Calls due to suicidal tendencies predominated over those due to attempted or threatened suicide during the first trimester of the year, while the opposite was the case during the third trimester. Conclusions. The results indicated differential characteristics of suicide calls that are potentially relevant for prevention in spite of the limitations of the present study.
