RESUMO
Background: The aims of this study were to describe the use of health services by patients attended for suicidal behavior by out-of-hospital emergency services and to identify the variables associated with the repetition of this behavior in Spain. Methods: An analytical, observational, retrospective study was carried out. A total of 554 patients attended by the mobile teams of the Primary Care Emergency (mt-PCES) of the Malaga Health District (Spain), after being coordinated by the 061 Emergency Coordination Center (ECC) were analyzed. Results: Of the total, 61.9% of the patients were women and the mean age was 43.5 years. Ninety-six percent (N = 532) of the patients attended by mt-PCES were transferred to hospital emergency services. Regarding clinical decision, of those transferred 436 persons (82%) were discharged home. Of the total sample 25.5% (N = 141) were referred to primary care, while 69% (N = 382) were referred to outpatient mental health care. Regarding follow up in the 6 months after being seen by emergency services, among those referred to a mental health facility, 64.4% (N = 246) attended the follow-up appointment while out of the total sample only 50.5% (N = 280) attended a follow-up appointment with an outpatient mental health service. Finally, it should be noted that 23.3% presented a relapse of suicidal behavior in the 6 months following index episode. The variables associated with repetition of suicidal behavior were older age, greater number of previous suicide attempts and having any contact with mental health services in the following 6 months. Conclusion: We believe that selective suicide prevention initiatives should be designed to target the population at risk of suicide, especially those receiving both out-of-hospital and in-hospital emergency services.
RESUMO
Abstract Introduction Suicide attempts are the most predictive risk factor for suicide deaths. Most people who attempt suicide receive care from out-of-hospital Emergency Services (OES), where these requests are managed and classified. Objective Validate the Emergency Coordination Center (ECC) classification for the detection of suicidal behavior requests. Method A descriptive, cross-sectional study of requests to the ECC of Málaga (Spain) during 2013 and 2014 was conducted. To classify the requests, the authors considered the ECC categorization when answering the call and the clinical assessment of the healthcare professional when attending the person who had made the call at the scene, which was considered the reference standard. To analyze the validity of the ECC classification system, sensitivity, specificity, and positive and negative predictive values (PPV and NPV) were calculated. Results The total number of requests for medical assistance analyzed was 112,599. The validity indicators of the classification system for suicidal behavior were sensitivity = 44.78%, specificity = 99.34%, PPV = 46.91% and NPV = 99.28%. Discussion and conclusion The ECC classification system has a lower capacity to detect the presence of suicidal behavior and a higher capacity to identify its absence in the requests received. OES provide key information on suicidal behavior requests as they can be one of the first places people with this problem go to. It would therefore be extremely useful to improve the classification systems for requests related to suicidal behavior.
Resumen Introducción Los intentos de suicidio constituyen el factor de riesgo más predictivo de todos los casos de suicidio consumado. La mayoría de las personas que intentan suicidarse reciben atención en los Servicios de Urgencias Extrahospitalarios (SUE) donde se gestionan y clasifican estas demandas. Objetivo Validar la clasificación del Centro Coordinador de Urgencias y Emergencias (CCUE) para detectar las demandas relacionadas con la conducta suicida. Método Se llevó a cabo un estudio descriptivo y transversal de las demandas al CCUE de Málaga (España) realizadas durante 2013 y 2014. Para su clasificación se tuvo en cuenta la categorización en el CCUE al responder la llamada y el juicio clínico del profesional sanitario cuando atiende al demandante in situ, considerando éste como patrón de referencia. Para evaluar la validez del sistema de clasificación se calcularon la sensibilidad, la especificidad y los valores predictivos positivo (VPP) y negativo (VPN). Resultados El total de demandas sanitarias analizadas fue de 112,599. Los indicadores de validez del sistema de clasificación para las demandas por conductas de suicidio fueron una sensibilidad = 44.78%, especificidad = 99.34%, VPP = 46.91% y VPN = 99.28%. Discusión y conclusión El sistema de clasificación del CCUE presenta una capacidad más baja para detectar presencia de conducta suicida comparada con una capacidad más alta para identificar su ausencia en las demandas recibidas. Los SUE aportan información relevante sobre las demandas por conducta suicida ya que pueden ser uno de los primeros lugares a los que acuden las personas con este problema. Por ello, sería de gran utilidad mejorar los sistemas de clasificación de las demandas por conducta suicida.
