An increasing proportion of older people live in Retirement Villages ('villages'). This population cites support for health-care issues as one reason for relocation to villages. Here, we examine whether relocation to villages is associated with a decline in hospitalisations.
Retrospective, before-and-after observational study.
Retirement villages, Auckland, New Zealand.
466 cognitively intact village residents (336 [72%] female); mean (SD) age at moving to village was 73.9 (7.7) years. Segmented linear regression analysis of an interrupted time-series design was used.
all hospitalisations for 18 months pre- and postrelocation to village.
acute hospitalisations during the same time periods.
The average hospitalisation rate (per 100 person-years) was 44.9 (95% confidence interval [CI] = 36.3-55.6) 18-10 months before village relocation, 58.9 (95% CI = 48.3-72.0) 9-1 months before moving, 47.9 (95% CI = 38.8-59.1) 1-9 months after moving and 62.4 (95% CI = 51.2-76.0) 10-18 months after moving. Monthly average hospitalisation rate (per 100 person-years) increased before relocation to village by an average of 1.2 (95% CI = 0.01-1.57, p = .04) per month from 18 to 1 month before moving, and there was a change in the level of the monthly average hospitalisation rate immediately after relocation (mean difference [MD] = -18.4 per 100 person-years, 95% CI = -32.8 to -4.1, p = .02). The trend change after village relocation did not differ significantly from that before moving.
Although we cannot reliably claim causality, relocation to a retirement village is, for older people, associated with a significant but non-sustained reduction in hospitalisation.
越来越多的老年人居住在退休村（“村庄”）中。这些人表示，他们搬迁到村庄是为了获得医疗保健方面的支持。在这里，我们研究了搬迁到村庄是否与住院率下降有关。
回顾性，前后观察研究。
新西兰奥克兰的退休村。
466 名认知功能正常的村庄居民（336 名[72%]为女性）；搬迁到村庄时的平均（SD）年龄为 73.9（7.7）岁。使用中断时间序列设计的分段线性回归分析。
搬迁到村庄前后 18 个月的所有住院治疗情况。
同期的急性住院治疗情况。
平均住院率（每 100 人年）为搬迁前 18-10 个月 44.9（95%置信区间[CI] = 36.3-55.6），搬迁前 9-1 个月 58.9（95% CI = 48.3-72.0），搬迁后 1-9 个月 47.9（95% CI = 38.8-59.1），搬迁后 10-18 个月 62.4（95% CI = 51.2-76.0）。在搬迁到村庄之前，从 18 个月到 1 个月前，每月平均住院率（每 100 人年）平均每月增加 1.2（95% CI = 0.01-1.57，p =.04），并且在搬迁后立即出现每月平均住院率水平的变化（平均差异[MD] = -18.4/100 人年，95% CI = -32.8 至 -4.1，p =.02）。搬迁到村庄后的趋势变化与搬迁前没有显著差异。
尽管我们不能可靠地声称存在因果关系，但对于老年人来说，搬迁到退休村与显著但非持续的住院率下降有关。
