Improvements in recovery rates may contribute to an increase in healthy life expectancy. It is unclear, however, whether such changes take place because health researchers traditionally deal with changes in incidence and survival from diseases. The purpose of this study was to test for the presence of time trends in the recovery rate from stroke.
We compared age patterns of recovery rates from stroke evaluated in 2 subcohorts represented in the National Long-Term Care Survey data linked with the Medicare service use files.
We found a statistically significant increase in recovery rate between 1994 and 1999 for females but not for males.
Time trends in recovery rate from stroke exist and can be detected from available data. The roles of influential factors and causes of sex difference in recovery improvement deserve further studies.
恢复率的提高可能有助于健康预期寿命的延长。然而，尚不清楚这种变化是否是因为健康研究人员传统上关注疾病的发病率和存活率的变化。本研究的目的是检验中风恢复率是否存在时间趋势。
我们比较了代表在与医疗保险服务使用文件相关的国家长期护理调查数据中链接的 2 个亚队列中的中风恢复率的年龄模式。
我们发现女性的恢复率在 1994 年至 1999 年间呈统计学显著增加，但男性则没有。
中风恢复率存在时间趋势，并且可以从现有数据中检测到。影响因素的作用和恢复改善的性别差异的原因值得进一步研究。
