本研究调查了一家大型城市大学附属县级医院两个住院精神科（危机稳定科和长期住院环境科）住院时间（LOS）的预测因素。假设有三个变量与较短的LOS独立相关：（1）较高的总体功能评估（GAF）量表评分，（2）不需要使用隔离或限制，（3）存在共病的物质使用障碍。从两个住院单位连续出院（n = 234）收集数据。进行了双变量检验，多元线性回归模型评估了LOS潜在决定因素的独立影响。存在共病人格障碍或物质使用障碍可预测危机稳定单元的较短LOS（n = 88）。有几个变量被认为是预测较短的LOS在长期停留的环境单位（n = 146），包括：非自愿的法律的状态出院，不需要隔离或限制，更高的入院GAF量表评分，女性性别，并存在共病的物质使用障碍。研究结果表明，在这种情况下，LOS的方差的很大一部分可以预测从基本的社会人口和临床因素，在医院的医疗图表。
This study investigated predictors of length of stay (LOS) for two inpatient psychiatric units (a crisis stabilization unit and a longer-stay milieu unit) in a large, urban, university-affiliated, county hospital. It was hypothesized that three variables would be independently associated with shorter LOS: (1) higher Global Assessment of Functioning (GAF) scale scores, (2) not requiring the use of seclusion or restraints, and (3) the presence of a comorbid substance use disorder. Data were collected on consecutive discharges (n = 234) from the two inpatient units. Bivariate tests were conducted, and multiple linear regression models assessed the independent effects of potential determinants of LOS. The presence of a comorbid personality disorder or substance use disorder was predictive of shorter LOS on the crisis stabilization unit (n = 88). Several variables were found to be predictive of shorter LOS on the longer-stay milieu unit (n = 146), including: involuntary legal status on discharge, not requiring seclusion or restraints, higher admission GAF scale score, female gender, and the presence of a comorbid substance use disorder. Findings indicate that a substantial portion of the variance in LOS in this setting can be predicted from basic sociodemographic and clinical factors available in hospital medical charts.
