ABSTRACT
PURPOSE: To evaluate adherence to anticholinergic therapy (AT) and clean intermittent self-catheterization (CISC) in patients with multiple sclerosis (MS) and to identify factors associated with poor adherence. METHODS: This single-center study prospectively included 49 patients suffering from MS who had been prescribed AT and/or CISC. Adherence was evaluated using a self-report questionnaire. The Expanded Disability Status Scale (EDSS), Patient Global Impression of Improvement, Mini-Mental State Examination, Urinary Symptom Profile, and Hospital Anxiety and Depression (HAD) instruments were administered, and the number of daily anticholinergic pills and/or catheterizations was noted. Whether patients were receiving concomitant intradetrusor botulinum toxin injections was assessed, as were barriers to treatment, side effects, number of spontaneous micturitions, reasons for the prescription, satisfaction, and difficulties. RESULTS: Only 38% of patients were adherent to AT. Experiencing side effects was related to nonadherence (P=0.02). Only 29% of patients were adherent to CISC. More intense voiding dysfunction (P<0.001), a higher frequency of CISC (P=0.03), and a higher EDSS score (P=0.02) were associated with better adherence. Conversely, the HAD score (P<0.001), depression (P<0.001), the persistence of spontaneous micturition (P<0.001), a blocking sensation during catheterization (P=0.04), and the need to adapt one's posture or gesture to perform catheterization (P=0.04) were associated with poorer adherence. CONCLUSIONS: Adherence to AT and CISC was poor in patients with MS suffering from bladder dysfunction. Several factors related to nonadherence were identified in this study, and addressing these factors might help to improve treatment adherence.
