Medication-related burden among Iraqi patients with ulcerative colitis: a cross-sectional study.

Ulcerative colitis (UC) is a chronic inflammatory bowel disease characterized by recurring periods of inflammation and remission, primarily affecting the colon. The concept of medication-related burden, which refers to the adverse effects experienced by patients due to conventional medical treatments, is relatively new in the field. This study aimed to measure medication-related burden among patients with ulcerative colitis in Iraq. The study was conducted at the Gastroenterology and Hepatology Teaching Hospital, Medical City, Baghdad, Iraq, from December 2022 to May 2023. We used the Arabic version of the Living with Medicines Questionnaire version 3 (LMQ-3) to explore medication-related burdens experienced by patients with UC. Eighty-six patients with ulcerative colitis were included. The mean of the total medication-related burden score was 107.5 ± 20.7. The findings showed that 45.3% of patients with UC had a moderate degree of medication-related burden, followed by minimum burden (44.2%), high burden (5.8%), and no burden (4.7%). The lowest median burden scores emerged in five domains: interactions with healthcare professionals, practical difficulties with medication use, medication side effects, medication effectiveness, and the impact on daily life. Conversely, the highest-burden scores were noted in the cost, concerns about medication use, and autonomy to vary the regimen domains. In multivariate analysis, none of the patient-related variables was independently correlated with the total medication-related burden score. A large proportion of the patients with UC who participated in the current study reported varying degrees of medication-related burden, with the majority having a minimum to moderate medication-related burden.
