Introduction: The involuntary placement and involuntary treatment of mentally ill patients are central issues in mental health care. Their massive impact upon the liberty and freedom of the persons concerned have made them a topic of controversial legal and ethical debates for more than 100 years. Coercive treatment in psychiatry, including the admission to a psychiatric hospital, remains an understudied issue [1]. The only replicated finding in this highly sensitive area is the significant cross-national variation concerning aspects such as provisions in mental health legislations and rates of involuntary admissions to psychiatric hospitals [2]. Objectives: The purpose of this study is to examine the impact of clinical and contextual characteristics on the decision to perform compulsory admission in psychiatric units in patients with diagnostic of schizophrenia who were attended and treated by a mobile home-care unit in the area of Barcelona (Multidisciplinary Team Support Specialist, EMSE in its Spanish acronym). Methods: We performed a cross-sectional retrospective study of the medical records of 362 patients with diagnosis of schizophrenia according to DSM-IV criteria who were attended at home by a mobile home-care unit in Barcelona. We collected the following data; age, number of visits done by EMSE at home, presence of violent behavior (evaluated with AVAT scale), awareness of disease (evaluated with SUMD scale), functionality of the patient (evaluated with WHO scale), global severity of disease (evaluated with GEP scale), clinical impression (evaluated with CGI scale), score in GAF scale, score in Positive PANSS scale, score in Negative PANSS scale and score in General PANSS scale. The sample was divided in two groups according to if patients were compulsory hospitalized or not. Results: We found more aggressiveness in the group of patients in which we decide to do compulsory hospitalization (mean AVAT score 4.87 Vs 2.99, p = 0.033). We also observed in patients compulsorily admitted to hospital worse awareness of disease (mean SUMD score 12.9 Vs 10.6, p = 0.008), major global severity of disease (mean GEP score 16.55 Vs 12.51, p = 0.047), worse clinical impression (mean CGI score 5.34 Vs 4.41, p< 0.001) and lower score in GAF scale (30.63 Vs 43.36, p< 0.001). Regarding to psychopathology we found higher score in positive PANSS scale in patients compulsorily admitted (29.44 Vs 22.54, p = 0.002), but we haven’t found statistically significant differences in negative PANSS score nor general PANSS score. Conclusions: As previously seen in the literature [3], in our study we observed that the decision to perform an involuntary admission is related with a worse awareness of disease, lower score at GAF scale and more aggressiveness in schizophrenic patients. In our sample we also observed that the decision to perform an involuntary admission is related with major severity of disease, a worse clinical impression and with higher positive psychotic symptoms.
