Key result
Medication nonadherence was present in 26.0% of adult cardiovascular patients, with being uneducated or having general education acting as a strong predictor (OR 4.7; 95% CI 2.0-11.2).
Why the study?
Medication nonadherence is common in CVD patients and may lead to increased costs, hospital admissions, and death, prompting an investigation into its prevalence and associated factors.

Medication nonadherence is common (26%) among cardiovascular patients in Al-Madinah, with lower education and retirement identified as significant predictors.
Background: Nonadherence to the medication schedule is common in patients with cardiovascular diseases (CVDs) and may have serious consequences including increased costs, hospital admissions, and death. Aim: In this study, we investigated the prevalence and associated factors of nonadherence in cardiovascular patients in Al-Madinah/Saudi Arabia. Settings and Design: This was a descriptive cross-sectional study carried out at tertiary cardiac center in Al-Madinah. Subjects and Methods: Study variables including sociodemographic characteristics and disease factors were collected from a random sample of patients attending the CVDs the clinic using a structured questionnaire. Adherence was assessed using the Culig's medication adherence scale. Statistical Analysis: Chi-square test and logistic regression analysis were used to evaluate factors associated with nonadherence. Results: A total of 200 adult cardiovascular patients completed the study; 100 (50.0%) were males and 186 (93.0%) resided in the city. The result showed that 26.0% (52/200) of the patients were nonadherent to medications, missing between 1 and 4 days of medication per week. Overall, 177 (88.5%) of the patients indicated that a healthcare worker explained the medications to them before dispensing. The most common reasons for nonadherence were: not being at home at the drug-taking time (84.6%), forgetfulness (82.7%), and fear of side effects (46.2%). Independent predictors of nonadherence were being retired (odds ratio [OR] 3.4; 95% confidence interval [C. I.] 1.3–9.4) and being uneducated or having general education (OR 4.7; 95% C. I. 2.0–11.2). Conclusion: Nonadherence rate was high and was found to be dependent upon patient-level factors. The study recommends improved patient education interventions to boost medication adherence in cardiovascular patients. Further studies are recommended.

A 2021 study conducted a cross-sectional in cardiovascular diseases (n=200). Being uneducated or having general education was evaluated on Medication nonadherence (OR 4.7, 95% CI 2.0-11.2). Medication nonadherence was present in 26.0% of adult cardiovascular patients, with being uneducated or having general education acting as a strong predictor (OR 4.7; 95% CI 2.0-11.2).
