Prevalence of urinary incontinence among institutionalized patients: a cross-sectional epidemiologic study in a midsized city in northern Italy.

OBJECTIVES

To determine the prevalence of urinary incontinence among institutionalized elderly people.

METHODS

A cross-sectional study was conducted on 839 subjects, resident in 14 residential or nursing homes. A questionnaire was administered to the study population and their clinical records were reviewed.

RESULTS

The overall prevalence of urinary incontinence was 54.5%, higher in women (59.8%) than in men (39.2%). The prevalence increased significantly with age, from 26.5% in subjects 65 years old or younger to 73.7% in subjects 95 years old or older; with worsening of mental status, from 36.2% in well-oriented subjects to 76.7% in poorly oriented subjects; and with worsening of mobility, from 23.8% in self-sufficient subjects to 82.1% in bedridden patients. The prevalence was significantly associated with parity, from 54.1% in nulliparous women to 65.4% in multiparous women. Urinary incontinence was also associated with urinary tract infection, constipation, and fecal incontinence.

CONCLUSIONS

The results of our study are in accordance with other similar studies. That more than one half of the elderly residents of nursing and residential homes have urinary incontinence shows the relevance of this condition. We believe that urinary incontinence in institutionalized elderly people can be managed essentially by measures of tertiary prevention, aimed at reducing the handicapping conditions and at slowing down the process of self-sufficiency impairment.
