Frequencies of undernutrition, bedsores, and deterioration in activities of daily living were compared in three Veterans Affairs nursing homes serving both chronic psychiatric patients and medical or neurological patients. The three facilities varied in the proportions of patients with adverse outcomes, with one home having noticeably higher rates for both subgroups of patients. In each home, the two subgroups were equally likely to show evidence of adverse outcome, suggesting that differences in the frequency of adverse outcomes among the facilities were accounted for by extrinsic factors related to quality of care rather than intrinsic factors related to patient characteristics.
在三家为慢性精神病患者以及内科或神经科患者提供服务的退伍军人事务疗养院中，对营养不良、褥疮以及日常生活活动能力下降的发生率进行了比较。这三家机构在不良后果患者的比例上存在差异，其中一家机构中两个患者亚组的发生率明显更高。在每家机构中，两个亚组出现不良后果迹象的可能性相同，这表明机构间不良后果发生率的差异是由与护理质量相关的外在因素而非与患者特征相关的内在因素造成的。
