Evaluation of Medication Adherence and its Predictors Among Psychiatric Outpatients at a Mental Healthcare Hospital in Lahore, Pakistan: A Cross-Sectional Study
AbstractThe study aimed to assess the level of medication adherence among psychiatric outpatients and to determine the main predictors associated with medication non-adherence. A cross sectional study was conducted among 298 psychiatric outpatients at Punjab Institute of Mental Health (PIMH), Lahore, Pakistan. A designed questionnaire was used as data collection tool and adherence was evaluated using MARS (Medication Adherence Rating Scale). Data was analyzed using SPSS version 21.0. Logistic regression was applied to determine the predictors of non-adherence. Medication adherence rate varied from low (39.3%) to high (60.7%) adherence. The impact of demographic factors such as age, gender, diagnosis, employment status and comorbidity on medication adherence were insignificant. Results of chi-square found that marital status, duration of illness from last visit, patient factors, medication factors, disease factors were significantly associated with adherence (p<0.05). Multivariate binary logistic regression indicated that qualification, marital status, number of tablets per day, duration of illness from last visit, patient factors, disease factors were the main predictors of medication non-adherence.
