Data on disease severity, co-morbidity, and process of care were obtained from the medical records of 356 patients without rheumatoid arthritis undergoing a first unilateral total hip replacement at four teaching hospitals in California and Massachusetts. Socio-demographic characteristics, functional status prior and subsequent to hospitalization, and improvement in health status were measured with a patient questionnaire 12 months after discharge. Completed questionnaires were received from 284 patients, a response rate of 79.8%. The questionnaire was acceptable to patients, reliable, and had good construct validity. The data indicate substantial benefits from hip arthroplasty. As expected, pre-surgical functioning was a strong predictor of outcomes 1 year after surgery. Controlling for pre-surgical functioning, age was not related to outcomes.
关于疾病严重程度、合并症及护理过程的数据，取自加利福尼亚州和马萨诸塞州四家教学医院中356例未患类风湿性关节炎且首次接受单侧全髋关节置换术患者的病历。出院12个月后，通过患者问卷对社会人口统计学特征、住院前后的功能状态以及健康状况改善情况进行了测量。共收到284例患者填写完整的问卷，回复率为79.8%。该问卷为患者所接受，具有可靠性且结构效度良好。数据表明髋关节置换术具有显著益处。正如预期的那样，术前功能是术后1年结果的有力预测指标。在控制术前功能的情况下，年龄与结果无关。
