OBJECTIVES: This study aimed to identify factors associated with long-term urinary catheterisation (LTUC) in community-dwelling older adults and to evaluate the risk of urinary tract infection (UTI) among people with LTUC.
DESIGN: Population-based observational study.
SETTING: Medical and long-term care insurance claims data from one municipality in Japan.
PARTICIPANTS: People aged ≥75 years living at home who used medical services between October 2012 and September 2013 (n=32 617).
OUTCOME MEASURES: (1) Use of LTUC, defined as urinary catheterisation for at least two consecutive months, to identify factors associated with LTUC and (2) the incidence of UTI, defined as a recorded diagnosis of UTI and prescription of antibiotics, in people with and without LTUC.
RESULTS: The 1-year prevalence of LTUC was 0.44% (143/32 617). Multivariable logistic regression analysis showed that the male sex, older age, higher comorbidity score, previous history of hospitalisation with in-hospital use of urinary catheters and high long-term care need level were independently associated with LTUC. The incidence rate of UTI was 33.8 and 4.7 per 100 person-years in people with and without LTUC, respectively. According to multivariable Poisson regression analysis, LTUC was independently associated with UTI (adjusted rate ratio 2.58, 95% CI 1.68 to 3.96). Propensity score-matched analysis yielded a similar result (rate ratio 2.41, 95% CI 1.45 to 4.00).
CONCLUSIONS: We identified several factors associated with LTUC in the community, and LTUC was independently associated with the incidence of UTI.
