Medication Adherence and Associated Factors among Chronic Heart Failure Clients on Follow Up Oromia Region, West Ethiopia

Medication Nonadherence and Associated Factors among Heart Failure Patients at University of Gondar Comprehensive Specialized Hospital, Northwest Ethiopia

Background

Medication nonadherence, being one of the best predictors of hospitalization, increases the mortality rate and hospital readmission and reduces the quality of life of heart failure (HF) patients. Therefore, this study is aimed at assessing medication nonadherence and associated factors among HF patients at the University of Gondar Comprehensive Specialized Hospital, Northwest Ethiopia.

Methods

A cross-sectional study was conducted among 245 adult patients with HF from June to August 2017. The data were collected by using the medication Adherence Report Scale (MARS-5) and then entered and analyzed using SPSS® (IBM Corporation) version 24. Summary statistics were presented using frequency, proportion, and mean. Binary logistic regression analysis was done for identifying factors associated with medication nonadherence with a 95% confidence level and p value of less than 0.05.

Results

Among 245 patients with HF, about a quarter (23.7%) of them were medication nonadherent. More than one-third (37%) of HF patients had a history of at least one HF medication discontinuation. Refilling problems (48%) and getting better from the illness (27%) were the most commonly reported reasons for nonadherence. Presence of comorbidity (AOR = 2.761; 95%CI = 1.364, 5.589), taking three or more types of medication (AOR = 2.805; 95%CI = 1.404, 5.60), and being unmarried (AOR = 2.638, 95%CI = 1.279, 5.443) was significantly associated with medication nonadherence.

Conclusion

The self-reported medication nonadherence among HF patients was considerably high. Refilling problems and getting better from the illness were the most commonly reported reasons for nonadherence. The presence of comorbid illness, taking three or more types of medication, and being unmarried was significantly associated factors of medication nonadherence. Awareness creation among patients on the importance of medication adherence and targeted efforts to assess and mitigate reasons for medication nonadherence may be helpful.

Relationship Among Treatment Adherence, Family Functioning, and Self-Care Agency in Colombian Patients With Cardiovascular Disease

BACKGROUND

Multiple factors affect treatment adherence in individuals with cardiovascular disease. However, information on the relationships among treatment adherence, family functioning, and self-care agency in these patients and their families is limited.

PURPOSE

This study was developed to determine the relationships among treatment adherence, family functioning, self-care agency, and sociodemographic variables in patients with cardiovascular disease. Self-care agency, as defined by Orem, is the dynamic process patients use to engage in their own healthcare that involves discerning and addressing factors that allow their making decisions that improve self-care abilities.

METHODS

This cross-sectional, observational-analytical study enrolled 151 adult patients with cardiovascular diseases who had undergone pharmacological and nonpharmacological treatments and 108 family members of these patients who had consented to participate. Measurements were performed using the "Questionnaire for measuring treatment adherence in patients with cardiovascular disease," the "Family Functioning Assessment Scale," and the "Self-care Agency Scale."

RESULTS

Of the 151 patients, 119 (78.8%) were assessed as having a low risk of nonadherence, 60 (39.7%) as having low family functioning, and 131 (86.8%) as having high self-care agency. Treatment adherence and self-care agency showed a moderate and significant correlation ( r = .66, p < .001). Similarly, treatment adherence and family functioning showed a low but significant correlation ( r = .35, p < .001). Moreover, significant multivariate associations were found among the variables of interest. Patients with a low risk of nonadherence were found to be more likely to have a secondary or postsecondary education, not to have vision or hearing problems, and to have a contributory affiliation mode with the health system or private health insurance. In addition, participants with moderate or high levels of family functioning were less likely to be workers or to not have hearing or vision problems. Finally, significant differences were noted between patients with low self-care agency and those with high self-care agency in terms of kinship relationship with family members and affiliation mode with the health system.

CONCLUSIONS/IMPLICATIONS FOR PRACTICE

The results of this research help clarify the issue of treatment adherence in patients with cardiovascular disease. Although family functioning and self-care agency were found to be low to moderately correlated with treatment adherence, relevant information regarding these variables and sociodemographic variables is presented in this study. Nurses may use these results as a reference to design nursing care plans and interventions to address the conditions of their patients more appropriately.
