Characteristics of a psychiatric setting, such as staffing intensity and scope of services, are examined to see if they contribute to explaining variation in length of stay over that explained by commonly available patient descriptors. For short-stay admissions (less than 31 days), only a small improvement in predictive ability was found. Implications for prospective payment systems are discussed.
研究精神病治疗机构的特征，如人员配备强度和服务范围，以确定它们是否有助于解释住院时间的差异，这种差异超出了通常可用的患者描述因素所能解释的范围。对于短期住院患者（少于31天），仅发现预测能力有小幅提高。文中还讨论了对预期支付系统的影响。
