Relationship between patient reports of urinary incontinence symptoms and quality of life measures.

OBJECTIVE: To determine if patient reports of urinary incontinence symptoms can predict quality of life as measured by the short forms of the Incontinence Impact Questionnaire and the Urogenital Distress Inventory, two standardized, disease-specific instruments.
METHODS: Telephone surveys were conducted of 384 community dwelling incontinent women, aged 60 years and older, who admitted to at least one episode of incontinence per week during the previous 3 months. Subjects were asked if they considered the incontinence a problem, as well as questions regarding volume and frequency of voids and urine loss. Each subject completed both standardized quality of life questionnaires. Responses to incontinence symptom questions were correlated with the standardized measures.
RESULTS: The question, "Do you consider this accidental loss of urine a problem that interferes with your day-to-day activities or bothers you in other ways?" was the best predictor of the subject's responses to both quality-of-life measures, with a correlation coefficient of 0.69 for the Incontinence Impact Questionnaire and 0.67 for the Urogenital Distress Inventory. The patients' symptoms that best correlated with both quality of life measures and the report of bothersome incontinence were frequent episodes of incontinence (0.40-0.58), greater amounts of urine loss (0.26-0.54), and more frequent voids (0.24-0.41).
CONCLUSION: Primary care practitioners may screen for problematic incontinence by asking if patients' incontinence is bothersome to them and by obtaining simple historic information on voiding and leaking patterns. These questions may provide an efficient tool to detect bothersome incontinence in older women.
