title: ICD-10 mental and behavioural disorders due to use of crack and powder cocaine as treated at a public psychiatric emergency service: an analysis of visit predictors.
abstract: The present study investigated the predictors of an increased number of visits from individuals with some of the diagnoses noted in chapter F14 of ICD-10, from calls to the emergency psychiatric unit of a general hospital in São Paulo state, Brazil, in the period 2011-2012. Poisson regression models were carried out for the outcome variable, accounting for number of subsequent visits to the psychiatric emergency unit. For the analysis of this outcome we took into account the exposure time of each individual in the study. Our findings point to a population at risk for frequent psychiatric emergency service visits: individuals over 25 years. This population should be targeted for interventions on entry into public healthcare due to increased psychiatric morbidity and greater clinical morbidity already confirmed by previous studies. We discussed the need of these individuals for special attention during the clinical or psychiatric emergency consultation which, unfortunately, may be the access point for the public health system. None of the other variables were related to the outcome of interest, such as those related to the level of individual entry into the care network before and after treatment, and other variables related to medical acts during the visit.
