The Effect of Applying the Information-Motivation-Behavioral Skills Model on Treatment Adherence in Patients with Cardiovascular Disease: A Quasi-Experimental Study

Determinants of medication adherence in hemodialysis patients: a cross-sectional study based on capability-opportunity-motivation and behavior model

BACKGROUND

Medication adherence is a key component of successful dialysis in end-stage renal disease (ESRD). The aim of this study was to use the Capability-Opportunity-Motivation and Behavior (COM-B) model in order to identify the most important determinants of medication adherence among ESRD patients.

METHODS

This research was a cross-sectional design that was conducted in two steps in 2021. In the first step, COM-B components of patients undergoing hemodialysis (HD) therapy were extracted through literature review. The second step was a cross-sectional study among 260 ESRD patients referred to the dialysis unit from Kermanshah, in the west of Iran. Data was collected using a written questionnaire by interviews. The data was analyzed in SPSS version 16 software.

RESULTS

The mean age of respondents was 50.52 years [95% CI: 48.71, 52.33], ranged from 20 to 75 years. The mean score of medication adherence was 11.95 [95% CI: 11.64, 12.26], ranged from 4 to 20. Medication adherence is higher among patients with higher education (P = 0.009) and those who were employed (P < 0.001) and was significantly related to income (r = 0.176), while it was inversely and significantly related to the medication duration (r=-0.250). Motivation (Beta: 0.373), self-efficacy (Beta: 0.244), and knowledge (Beta: 0.116) are stronger determinants of medication adherence.

CONCLUSION

COM-B model can be proposed as an integrated framework in predicting medication adherence among ESRD patients. Our findings provide theory-based recommendations that can help future clinical and research decision-making for the development, implementation, and evaluation of treatment adherence interventions in Iranian ESRD patients. The use of COM-B model can provide a comprehensive explanation about medication adherence in ESRD patients. Future research should be focus on increasing motivation, self-efficacy and knowledge of Iranian ESRD patients in order to increasing medication adherence.

Experience of adherence to treatment among patients with coronary artery disease during the COVID-19 pandemic: A qualitative study

Background: The coronavirus disease 2019 (COVID-19) pandemic has caused patients with chronic diseases to face various challenges. The present qualitative study aimed to explore adherence to treatment in patients with coronary artery disease (CAD) during the COVID-19 pandemic. Methods: This qualitative content analysis was conducted from September 2020 to February 2021. Online in-depth interviews were conducted with 15 patients with CAD after discharge from Nemazi and Al-Zahra heart hospitals, Shiraz, Iran. Data management was done via MAXQDA 12 software using conventional content analysis based on the method proposed by Graneheim and Lundman. Results: The results revealed three main categories, nine subcategories, and 431 primary codes. The first category was 'improved self-care in the shadow of COVID-19' (Improving self-care due to fear of COVID-19, 'utilization of alternative strategies, and reinforcement of self-care beliefs). The second category was 'redefinition of support systems' (need for a support system, seeking for alternative support systems, and changes in social interactions). The last category was 'barriers to treatment adherence' (shortage of financial resources, need to adjust with working conditions, and mental conflicts). Conclusion: The results indicated that the COVID-19 threats encouraged the patients with CAD to adhere to their care principles. Nonetheless, the restrictions resulting from the pandemic caused problems in adherence to treatment. Thus, redefinition of the support systems in accordance with the present conditions are recommended.

Experiences of the Patients with Behcet's Syndrom from Adherence to Treatment: A Qualitative Content Analysis

Background

Adherence to treatment plays an important role in the effectiveness of treatment in patients with Behcet's Syndrome (BS). An in-depth understanding of the experiences of patients with BS will help to improve the patients' management. The present qualitative study aimed to explore the experiences of patients with BS from adherence to treatment.

Methods

This qualitative study was conducted during February-September 2019 at Shahid Motahari Behcet's Clinic in Shiraz, Iran. Data were collected through eight unstructured observations and 22 individual in-depth semi-structured interviews with 20 participants (15 patients with BS, three family members, and two rheumatologists). Data analysis was performed simultaneously with data collection, using the conventional content analysis as proposed by Graneheim and Lundman. Data were managed using MAXQDA 10 software.

Results

Data analysis resulted in 21 sub-categories, seven categories, and three themes. The themes included barriers to treatment adherence (inability to cope with treatment and challenges in access to health care), facilitators of treatment adherence (incentives, receiving support, and striving to adapt to illness), and missing aspects of the treatment program (inadequate patient education and the neglect of lifestyle modification).

Conclusion

The barriers to and facilitators of treatment adherence as well as the missing aspects of the treatment program of patients with BS were identified. Adherence to treatment is not only determined by the patients, but also affected by the support system and relies upon the existing context and the nature of the treatment plan. These parameters should be considered during patient management to effectively promote treatment adherence.
