Non‐adherence to pharmacotherapy and its associated factors among patients with angina in Jordan

Factors Associated with Medication Non-Adherence in Patients with Dyslipidemia

Lack of medication adherence among patients with dyslipidemia negatively affects health-related outcomes. This study aims to evaluate medication adherence; we also aim to investigate the predictors of non-adherence among patients with dyslipidemia in Jordan. Medication adherence was evaluated in a total of 228 dyslipidemia patients. The Beliefs about Medicines Questionnaire was also used to assess patients' beliefs about medications. The majority of the current study participants (73.2%) reported non-adherence to the prescribed medications. There were significant negative associations between medication adherence and concerns of prescription drug use (B = -0.41, p-value < 0.01), duration of dyslipidemia (B = -0.22, p-value < 0.01), and the number of medications (B = -0.64, p-value < 0.01). Positive associations were found between medication adherence and the necessity of prescription drug use (B = 0.43, p-value < 0.01), taking statin and fibrate (B = 2.04, p-value < 0.01), and moderate-intensity statin (B = 2.34, p-value < 0.01). As for patients' beliefs about medications, the item "My medicine to lower my cholesterol disrupted my life" had the highest mean (3.50 ± 0.99). This study revealed a low adherence rate to medication among patients with dyslipidemia. It also demonstrates modifiable factors such as beliefs regarding perceived risk, medication harms, treatment duration, and the number of medications associated with poor adherence in patients with dyslipidemia.

Lipid control and its associated factors among patients with dyslipidaemia in Jordan

BACKGROUND

Lipid control represents a cornerstone in the management of atherosclerotic cardiovascular disease (ASCVD). Nevertheless, little research has explored the factors associated with poor lipid control in patients with dyslipidaemia.

OBJECTIVE

The study aim was to investigate the variables associated with poor lipid control among patients with dyslipidaemia in Jordan.

METHOD

In addition to socio-demographics, disease and medication-related variables, lipid profile including total cholesterol, LDL-C, HDL-C and triglyceride and other biomedical variables were collected for patients diagnosed with dyslipidaemia using hospital medical charts at three major outpatient clinics in Jordan. The validated 4-item medication adherence scale and the beliefs about medications questionnaire were used to evaluate medication adherence and medication beliefs among the study participants. The participants were classified to have controlled and uncontrolled dyslipidaemia using recent AHA guidelines. A stepwise forward conditional binary regression was conducted to explore the variables significantly and independently associated with dyslipidaemia control. A P-value of < .05 was considered statistically significant.

RESULTS

A total of 228 patients participated in the study. Most of the study participants (61%) were classified to have uncontrolled lipid profile and 60.1% of them were found to have ASCVD. Regression analysis revealed that increased necessity for dyslipidaemia medications increased the odds of dyslipidaemia control (OR = 1.14), whereas active smoking (OR = 0.42), low medication adherence (OR = 0.0.8) and the presence of ASCVD (odd ratio = 0.24) were significantly associated with poor dyslipidaemia control.

CONCLUSION

Lipid profile has considerable scope for improvement in patients with dyslipidaemia in Jordan. Improving medication adherence by emphasising on medication necessity and simplifying the prescribed dosage regimen, particularly in smoking patients and those who have ASCVD, should be particularly considered in future clinical pharmacy service programmes aim at improving lipid control and health outcomes in patients with dyslipidaemia.
