Patients (n = 103) admitted to an inpatient geriatric care unit focusing on restoration of functional status were compared to similar patients (n = 75) admitted to a control-unit. Study unit patients showed significantly greater improvement in basic functional capabilities from admission to discharge than did control-unit patients. A mixed picture evolved when length of stay and total charges of study and control-unit patient were compared by diagnostic-related groups.
将入住以恢复功能状态为重点的老年住院护理单元的患者（n = 103）与入住对照单元的类似患者（n = 75）进行比较。研究单元的患者从入院到出院在基本功能能力方面的改善明显大于对照单元的患者。当按诊断相关组比较研究单元和对照单元患者的住院时间和总费用时，出现了复杂的情况。
