Abstract

Objectives

To identify 1-year period prevalence, 5-year incidence rate, and risks for urinary incontinence (UI) for people living with dementia.

Design

Retrospective cohort study.

Setting and Participants

Participants completed an International Residential Assessment Instrument Home Care (interRAI-HC) assessment in a 5-year period between August 1, 2016 and July 31, 2021 in Aotearoa New Zealand (N = 109,964).

Methods

For prevalence analysis, a dementia cohort was selected for a 1-year period from August 1, 2020 to July 31, 2021 (n = 7775). For incidence analysis, participants in the dementia cohort were followed from the first dementia diagnosis during the 5-year period. Dementia was identified by combining diagnoses of “Alzheimer's disease” and “Dementia other than Alzheimer's disease.” Participants were coded with UI if they were infrequently, occasionally, or frequently incontinent or if continence was managed with catheter/ostomy. Univariate and multivariate logistic regression analyses identified risk factors predicting UI onset. Cox regression analysis compared survival curves (months without UI) of the dementia and non-dementia cohorts, adjusting for variables significantly associated with incident UI in either cohort.

Results

The 1-year period (August 1, 2020 to July 31, 2021) prevalence of UI was 50.1% among people with dementia. The 5-year incident UI rate was 30.2 per 100 person-years for the dementia cohort and 24.5 per 100 person-years for the non-dementia cohort. Parkinson's disease posed the greatest risk of UI in both cohorts [dementia cohort odds ratio (OR), 3.0; 95% CI, 2.1–4.2; non-dementia cohort OR, 1.7; 95% CI, 1.4–2.0]. Controlling for risk factors, the hazard ratio for UI was 1.4 for people with dementia.

Conclusions and Implications

UI affects a significant proportion of people with dementia in Aotearoa New Zealand. Health professionals should directly ask about UI and consider living arrangements and comorbidities for people with dementia. Data-driven insights from interRAI-HC can guide resource allocation and service planning.

新西兰奥特亚罗瓦社区痴呆症患者尿失禁的发生率、患病率和风险:一项 interRAI 研究。
目的确定痴呆症患者的 1 年患病率、5 年发病率和尿失禁(UI)风险:设计:回顾性队列研究:参与者在 2016 年 8 月 1 日至 2021 年 7 月 31 日的 5 年间在新西兰奥特亚罗瓦完成了国际居住评估工具家庭护理(interRAI-HC)评估(N = 109,964):为了进行患病率分析,我们选取了 2020 年 8 月 1 日至 2021 年 7 月 31 日这 1 年期间的痴呆症队列(n = 7775)。在发病率分析中,对痴呆症队列中的参与者从首次诊断痴呆症开始进行为期 5 年的随访。痴呆症通过合并 "阿尔茨海默病 "和 "阿尔茨海默病以外的痴呆症 "诊断来确定。如果参与者很少、偶尔或经常大小便失禁,或使用导尿管/造口术控制大小便失禁,则将其编码为 UI。单变量和多变量逻辑回归分析确定了预测尿失禁发病的风险因素。Cox 回归分析比较了痴呆组和非痴呆组的生存曲线(无尿失禁的月数),并调整了任何一组中与尿失禁事件显著相关的变量:痴呆症患者在 1 年内(2020 年 8 月 1 日至 2021 年 7 月 31 日)的尿失禁发生率为 50.1%。痴呆症队列的 5 年尿失禁发生率为每 100 人年 30.2 例,非痴呆症队列为每 100 人年 24.5 例。在两个队列中,帕金森病造成的尿失禁风险最大(痴呆队列奇数比 [OR],3.0;95% CI,2.1-4.2;非痴呆队列 OR,1.7;95% CI,1.4-2.0)。在控制风险因素后,痴呆症患者的尿失禁危险比为1.4:在新西兰奥特亚罗瓦,有相当一部分痴呆症患者受到尿崩症的影响。医疗专业人员应直接询问尿失禁情况,并考虑痴呆症患者的生活安排和合并症。从interRAI-HC中获得的数据驱动的见解可以指导资源分配和服务规划。
