Effect of teaching health-promoting behaviors on the care burden of family caregivers of hemodialysis patients: a four-group clinical trial

Abstract

IntroductionChronic kidney disease could have a profound effect on the life of patients and family caregivers. The caregivers’ care burden increases as the disease progresses. Interventions reducing care burden should be investigated. Educational interventions could affect family caregivers’ care burden among hemodialysis patients. However, most studies and interventions have focused on caregivers. Therefore, this study aims to compare the effect of teaching Health-promoting behaviors on the care burden of family caregivers of hemodialysis patients.Materials and methodsThis trial was conducted using a pretest-posttest design and follow-up after one month. Hemodialysis patients and their family caregivers were selected using convenience sampling method. In total, 124 patient-caregiver pairs were divided into four groups of patient-centered education, caregiver-centered education, Patient and caregiver education and control by block randomization (15 blocks of 8 members and 1 block of 4 members) (n = 31 pairs per group). The intervention (teaching health-promoting behaviors) was performed in 8 sessions using the teach-back method, except for the control. The data were collected by patient and caregiver demographic forms and Novak and Guest care burden inventory as well as following the treatment regimen in three stages (before, immediately after and one month after the intervention). Demographic variables were compared among the four groups using ANOVA, Kruskal-Wallis and Chi-square test. The intragroup comparison of the main variables was made using the repeated measures ANOVA with modified LSD post hoc test. The intergroup comparison was made by one-way ANOVA with LSD post hoc test.ResultsOut of 124 caregivers participating in the study, 68 (54.8%) were female. Also, out of 124 patients participating in the study, 86 (69.4%) were male. The mean age of the caregivers and patients was 39.2 ± 11.31 and 54.23 ± 14.20 years old, respectively. There was a statistically significant difference in the mean total care burden scores of the pre-test and post-test between the four groups (p < 0.001). The total care burden decreased in patient-centered, caregiver-centered and Patient and caregiver education groups. However, this reduction in the caregiver-centered and Patient and caregiver education groups was significantly higher than the patient-centered education group (p < 0.001).ConclusionThe results revealed teaching health-promoting behaviors reduced care burden. Moreover, caregiver-centered approach could reduce care burden more than patient-centered approach. Therefore, this could be used as a supportive method to improve the health of patients and caregivers.Trial registration number (TRN)IRCT20090522001930N4.Date of registration2021-11-12.
