The present study evaluates the response comparability between 361 elderly hip fracture patients admitted from the community to seven Baltimore area hospitals between 1984 and 1986 and interviewer selected proxies on items pertaining to patients' pre-fracture health and functional status. Agreement across items ranges from very poor to good and varies with respect to the health or functional area assessed. Proxies tend to overestimate patient disability relative to the patients themselves, especially with regard to capacity to perform instrumental activities of daily living. Although proxies who report the greatest contact with patients respond most comparably to the patients, when they do disagree, proxies with the greatest patient contact tend to overestimate patient disability. The authors suggest that attention to item construction and phrasing may improve response comparability.
本研究评估了1984年至1986年间从社区收治到巴尔的摩地区七家医院的361名老年髋部骨折患者与采访者挑选的代理人在患者骨折前健康状况和功能状态相关项目上的反应可比性。各项目的一致性从很差到良好不等，且因所评估的健康或功能领域而异。相对于患者自身，代理人往往高估患者的残疾程度，尤其是在日常生活工具性活动能力方面。尽管与患者接触最多的代理人的反应与患者最为可比，但当他们意见不一致时，与患者接触最多的代理人往往高估患者的残疾程度。作者建议，关注项目构建和措辞可能会提高反应可比性。
