Medically recognized urinary incontinence and risks of hospitalization, nursing home admission and mortality.
OBJECTIVE
this study examined the association between medically recognized urinary incontinence and risk of several disease conditions, hospitalization, nursing home admission and mortality.


METHODS
review and abstraction of medical records and computerized data bases from 5986 members, aged 65 years and older, of a large health maintenance organization in northern California.


RESULTS
there was an increased risk of newly recognized urinary incontinence following a diagnosis of Parkinson's disease, dementia, stroke, depression and congestive heart failure in both men and women, after adjustment for age and cohort. The risk of hospitalization was 30% higher in women following the diagnosis of incontinence [relative risk (RR) = 1.3, 95% confidence interval (CI) = 1.2-1.5] and 50% higher in men (RR = 1.5, 95% CI = 1.3-1.6) after adjustment for age, cohort and co-morbid conditions. The adjusted risk of admission to a nursing facility was 2.0 times greater for incontinent women (95% CI = 1.7-2.4) and 3.2 times greater for incontinent men (95% CI = 2.7-3.8). In contrast, the adjusted risk of mortality was only slightly greater for women (RR = 1.1; 95% CI = 0.99-1.3) and men (RR= 1.2; 95% CI= 1.1-1.4).


CONCLUSIONS
urinary incontinence increases the risk of hospitalization and substantially increases the risk of admission to a nursing home, independently of age, gender and the presence of other disease conditions, but has little effect on total mortality.
