Identifying which factors contribute to involuntary psychiatric hospitalization may support initiatives to reduce its frequency. This study examines the sociodemographic, clinical, and contextual factors associated with involuntary hospitalization of patients from five Portuguese psychiatric departments in 2002, 2007 and 2012. Data from all admissions were extracted from clinical files. A Poisson generalized linear model estimated the association between the number of involuntary hospitalizations per patient in one year and sociodemographic, clinical, and contextual factors. An increment of involuntary hospitalizations was associated with male gender [exp( $$\widehat{\upbeta }$$ ) = 1.31; 95%CI 1.06–1.62, p < 0.05], having secondary and higher education [exp( $$\widehat{\upbeta }$$ ) = 1.45; 95%CI 1.05–2.01, p < 0.05, and exp( $$\widehat{\upbeta }$$ ) = 1.89; 95%CI 1.38–2.60, p < 0.001, respectively], a psychiatric diagnosis of psychosis [exp( $$\widehat{\upbeta }$$ ) = 2.02; 95%CI 1.59–2.59, p < 0.001], and being admitted in 2007 and in 2012 [exp( $$\widehat{\upbeta }$$ ) = 1.61; 95%CI 1.21–2.16, p < 0.01, and exp( $$\widehat{\upbeta }$$ ) = 1.73; 95%CI 1.31–2.32, p < 0.001, respectively]. A decrease in involuntary hospitalizations was associated with being married/cohabitating [exp( $$\widehat{\upbeta }$$ ) = 0.74; 95%CI 0.56–0.99, p < 0.05], having experienced a suicide attempt [exp( $$\widehat{\upbeta }$$ ) = 0.26; 95%CI 0.15–0.42, p < 0.001], and belonging to the catchment area of three of the psychiatric services evaluated [exp( $$\widehat{\upbeta }$$ ) = 0.65; 95%CI 0.49–0.86, p < 0.01, exp( $$\widehat{\upbeta }$$ ) = 0.67; 95%CI 0.49–0.90, p < 0.01, and exp( $$\widehat{\upbeta }$$ ) = 0.67; 95%CI 0.46–0.96, p < 0.05 for Hospital de Magalhães Lemos, Centro Hospitalar Psiquiátrico de Lisboa and Unidade Local de Saúde do Baixo Alentejo, respectively]. The findings suggest that involuntary psychiatric hospitalizations in Portugal are associated with several sociodemographic, clinical, and contextual factors. This information may help identify high-risk patients and inform the development of better-targeted preventive interventions to reduce these hospitalizations.

葡萄牙与非自愿精神病院住院治疗相关的因素

确定哪些因素会导致非自愿性精神病住院，可以支持减少其频率的举措。这项研究调查了2002年，2007年和2012年来自葡萄牙五个精神科的患者非自愿住院的社会人口统计学，临床和背景因素。所有入院数据均摘自临床档案。泊松广义线性模型估计了每名患者一年中非自愿住院的次数与社会人口统计学，临床和背景因素之间的关联。男性非自愿住院的增加[exp（$$ \ widehat {\ upbeta} $$）= 1.31; 95％CI 1.06-1.62，p <0.05]，具有中学和高等教育[exp（$$ \ widehat {\ upbeta} $$）= 1.45；95％CI 1.05–2.01，p <0.05，和exp（$$ \ widehat {\ upbeta} $$）= 1.89; 95％CI 1.38–2.60，p <0.001，分别是精神病的精神病学诊断[exp（$$ \ widehat {\ upbeta} $$）= 2.02; 95％CI 1.59-2.59，p <0.001]，并于2007年和2012年被接纳[exp（$$ \ widehat {\ upbeta} $$ = 1.61; 95％CI 1.21-2.16，p <0.01，exp（$$ \ widehat {\ upbeta} $$）= 1.73；95％CI 1.31–2.32，p <0.001]。非自愿住院的减少与已婚/同居有关[exp（$$ \ widehat {\ upbeta} $$ = 0.74; 95％CI 0.56-0.99，p <0.05]，曾经历过自杀未遂[exp（$$ \ widehat {\ upbeta} $$）= 0.26; 95％CI 0.15-0.42，p <0.001]，属于评估的三个精神科服务的集水区[exp（$$ \ widehat {\ upbeta} $$ = 0.65; 95％CI 0.49–0.86，p <0.01，exp（$$ \ widehat {\ upbeta} $$）= 0.67；95％CI 0。49–0.90，p <0.01，exp（$$ \ widehat {\ upbeta} $$）= 0.67; 马萨诸塞州莱马斯医院，里斯本Psiquiátrico里斯本中心医院和圣保罗德拜索阿连特茹地方大学的95％CI为0.46-0.96，p <0.05。研究结果表明，葡萄牙的非自愿性精神病住院与一些社会人口统计学，临床和背景因素有关。这些信息可能有助于识别高危患者，并为开发针对性更强的预防性干预措施以减少此类住院治疗提供信息。研究结果表明，葡萄牙的非自愿性精神病住院与一些社会人口统计学，临床和背景因素有关。这些信息可能有助于识别高危患者，并为开发针对性更强的预防性干预措施以减少此类住院治疗提供信息。研究结果表明，葡萄牙的非自愿性精神病住院与一些社会人口统计学，临床和背景因素有关。这些信息可能有助于识别高危患者，并为开发针对性更强的预防性干预措施以减少此类住院治疗提供信息。
