There have been significant reductions in numbers of psychiatric beds and length of stay (LOS) worldwide, making LOS in psychiatric beds an interesting outcome. The objective of this study was to find factors measurable on admission that would predict LOS in the acute psychiatric setting.
This was a prospective, observational study.
Overall, 385 subjects were included. The median LOS was 25 days. In the final model, six variables explained 14.6% of the variation in LOS: not having own income, psychiatric admissions in the preceding 2 years, high Clinical Global Impression and Brief Psychiatric Rating Scale scores, diagnosis of schizophrenia, and history of attempted suicide. All variables were associated with longer LOS, apart from history of attempted suicide.
Identifying patients who will need to stay longer in psychiatric beds remains a challenge. Improving knowledge about determinants of LOS could lead to improvements in the quality of care in hospital psychiatry.
全球范围内精神科病床数量和住院时间（LOS）都有显著减少，使得精神科病床的住院时间成为一个有趣的研究结果。本研究的目的是找出入院时可测量的因素，这些因素能够预测急性精神科环境中的住院时间。
这是一项前瞻性观察性研究。
总共纳入了385名受试者。住院时间中位数为25天。在最终模型中，六个变量解释了住院时间变异的14.6%：没有个人收入、过去2年内有精神科住院史、临床总体印象量表和简明精神病评定量表得分高、精神分裂症诊断以及自杀未遂史。除自杀未遂史外，所有变量均与较长的住院时间相关。
识别出需要在精神科病床停留更长时间的患者仍然是一项挑战。提高对住院时间决定因素的认识可能会改善医院精神科的护理质量。
