Burden levels and predictive factors among caregivers of hemodialysis patients: a cross-sectional study in Oman

Background: Caring for individuals with chronic kidney disease (CKD) is a highly demanding task that can adversely affect the physical and psychological well-being of caregivers.

Objective: This study aimed to investigate the burden experienced by caregivers of patients undergoing hemodialysis (HD) in Oman and explore the factors associated with this burden, including demographic and medical characteristics.

Methods: A descriptive cross-sectional was employed. Caregiver burden was assessed, and demographic and medical variables were examined among caregivers of HD patients. A total of 326 unpaid family caregivers completed the Zarit Burden Interview scale, demographics and some medical variables. Linear multiple regression analyses were conducted to identify factors linked to caregiver burden.

Results: Of the caregivers, 62.9% reported a minimal burden, 21.8% experienced mild-to-moderate burden, 8.6% faced moderate-to-severe burden, and 6.7% encountered a severe burden. The final multiple regression model demonstrated statistical significance compared to the constant (F = 8.68, p < 0.001), with eight predictors explaining 18% of the variance, and caregivers' satisfaction with health emerged as the only significant predictor.

Conclusion: A substantial portion of caregivers reported minimal burden. These findings suggest the need for further in-depth investigations into factors contributing to this favourable outcome. Furthermore, caregivers' satisfaction with health was the only significant predictor of their burden. Healthcare providers need to give special attention to this point and conduct periodic assessments of the primary caregivers' health. Implementing improvements in the healthcare system based on these findings could enhance the overall caregiving experience for HD patients and their caregivers.
