Factors related to treatment adherence behaviors among old-age hemodialysis patients in Hamadan, Iran: the application of the extended theory of planned behavior during Covid-19 pandemic

Abstract

Purpose This study aimed to identify the factors related to treatment adherence behaviors among old-age hemodialysis patients in Hamadan based on the Extended Theory of Planned Behavior (ETPB) during the covid-19 pandemic. Methods This cross-sectional study was conducted from January to March 2021 in Hamadan, Iran. 191 hemodialysis patients were recruited who were referred to hemodialysis centers via the census method. Data were collected by a questionnaire containing items on socio-demographic information, End-Stage Renal Disease Adherence (ESRD-Adherence) Questionnaire, and ETPB constructs scale. Data analysis was performed using descriptive statistics and structural equation modeling. Results The mean (SD) age of participants was 62.49 (10.66). Also, the mean (SD) hemodialysis vintage/Month of them was 36.56 (43.34). Moreover, Treatment Adherence Behaviors are associated with education level, sex, and marital status (p < 0.001). Besides, Perceive Behavior Control (β = 0.414, t-value = 3.810) associated with intention. Also, intention (β = 0.158, t-value = 1.976) was associated to adherence behaviors. No significant associations were observed between positive attitudes, subjective norms, a perceived threat with intention, and adherence behaviors. The model explained about 54% of the variance of adherence behaviors. Finally, the goodness of fit index of 0.78, indicating the model good fit. Conclusion The present study demonstrates that some of the ETPB constructs such as perceived behavior control and intention are useful to improve adherence among the oldest hemodialysis patients. Also. This framework is revealed alongside the theory of planned behavior (TPB) applicable in the treatment adherence of old-age hemodialysis patients.

Factors Affecting Adherence to Hemodialysis Therapy Among Patients With End-Stage Renal Disease Attending In-Center Hemodialysis in Al-Ahsa Region, Saudi Arabia

“…Age distribution revealed that the majority of patients fell within the 41-60 years age group (44.8%), indicating that this age group often faces multiple challenges, including comorbid conditions, family responsibilities, and the need for additional support. Alkatheri et al show that older significantly increase their adherence level to hemodialysis in contrast with our findings in which age is not significantly associated with adherence [16].…”

The relationship between hemodialysis patients’ treatment adherence, procrastination, and difficulty in emotion regulation: A cross-sectional study in southeast Iran

“…Some studies supported our study regarding the relationship between age and treatment adherence. Sheikh et al (2022), Varghese (2021, Rafiee-Vardanjani et al (2013), andKhalili et al (2011) found a significant relationship between hemodialysis patients' age and treatment adherence, so that older patients were more adherent than younger patients. They also found an association between income, sex, education, marital status, and treatment adherence that was not consistent with our results.…”

Medication adherence among hemodialysis patients: the impact of pharmacist-led motivational interviewing

“…Study done by Sheikh and colleagues among 191 HD patients, also reported significant difference in medication adherence was higher in married HD patients compared to single or other groups (divorced/widow/partner death). 28 In addition, there is evidence showing, close family members support promoted for improved patient adherence. 29 After the pharmacist intervention in providing MI, the post adherence score shows more than half, 57.1% of the recruited patients having high medication adherence at the end of the study.…”
