• 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 (<31 days), only a small improvement in predictive ability was found. Implications for prospective payment systems are discussed.
