PURPOSE: This study aimed to determine whether there is a relationship between the lack of medication knowledge and the self-reported rates of patient medication adherence. METHODS: Patients eligible to participate in the study had been taking oral medication at least once daily over the course of a minimum of three consecutive months before recruitment to the study. All participants were older than 18 years. The level of each patient's knowledge of his or her medication was randomly assessed by a trained fifth-year pharmacy student through an adapted questionnaire. In addition, patient adherence was evaluated via utilization of the Morisky Medication Adherence Scale. RESULTS: Of the 765 study participants (mean ± SD age = 55.45 ± 15.05 years, range = 20-91 years, 56.2% women), 58.0% reported adherence to their medication regimen and 64.5% professed optimal knowledge of their medication. The mean duration of medication utilization was 26.77 ± 40.62 months (range = 3-504 years). A statistically significant correlation exists between the total medication knowledge score on the questionnaire and the level of medication adherence (r = -0.964, p < 0.001). CONCLUSION: Improvement in the patient's knowledge of medications taken would bear a positive effect on medication adherence.
