Lower urinary tract symptoms and health-related quality of life in Hong Kong primary care: a cross-sectional study.

Abstract

To estimate the prevalence of lower urinary tract symptoms (LUTS) in primary care using the International Continence Society symptom definition; to evaluate the association between LUTS and health-related quality of life (HRQOL); and to evaluate the treatment gaps. Patients aged 40 and above were randomly recruited in a Hong Kong public primary care. Patients were asked (i) how often they experienced 18 individual LUTS during the past 4weeks and (ii) whether they had sought treatments for their LUTS. The 12-Item Short Form Health Survey version 2 (SF-12 v2) and the modified Incontinence Impact Questionnaire-Short Form (IIQ-7) were used to measure HRQOL. 500 patients completed the survey. 75.8% of the patients had at least one LUTS "at least sometimes", with patients with a combination of storage, voiding, and post-micturition symptoms being the most prevalent (22.2%), followed by a combination of voiding and storage symptoms (14%). Only 14% of LUTS patients had sought treatments for their LUTS. LUTS was associated with a negative effect in all domains of the SF-12 v2 and IIQ-7 and patients with a combination of storage, voiding, and post-micturition symptoms had the worst HRQOL. Finally, having a combination of storage, voiding, and post-micturition symptoms and poorer HRQOL were factors associated with having sought treatments for LUTS. A high prevalence of LUTS but low treatment-seeking rates implied possible unmet needs of LUTS patients in primary care, suggesting the potential for more active interventions to alleviate the negative impact of LUTS on patients' HRQOL.
