ObjectivesDrug therapy is the mainstay of treatment for overactive bladder (OAB), but antimuscarinic agents possess side-effects. These side-effects decrease the patients' quality of life. We therefore assessed the impact of side-effects on health-related quality of life (HR-QoL) through an analysis of EQ-5D questionnaire.
MethodsThis study was designed to investigate the patients' satisfaction by quality weight of health status as affected by the side-effects of OAB medications. Patients who had OAB symptoms lasting longer than 3 months and have experienced side-effects after any antimuscarinic treatments filled in the EQ-5D questionnaire. The enrolled patients had two EQ-5D questionnaires for two different health statuses, i.e., presence or absence of side-effects. Quality weight was calculated using the ED-5D health status score with Korean tariff.
ResultsOne hundred patients were enrolled and completed the HR-QoL questionnaire. The most prevalent side-effect was dry mouth (61%) and 28% patients had dry mouth and constipation concurrently. Most of the patients with side-effects tried to endure and overcome these side-effects (79%), but 10% desired a change in medication, and 6% stopped medication altogether. The quality weight of EQ-5D without side-effects was 0.863, while the quality weight with side-effects was 0.666 (P < 0.001). The VAS score was 79 in patient without side-effects and 57 in those with side-effects, supporting the results of quality weight assessment.
ConclusionsOveractive bladder patients may enjoy a better quality of life if side-effects associated with antimuscarinic therapy are fewer.
