Background: Although dialysis treatment is considered as a life-saving treatment for chronic renal failure patients, the caregivers face challenges in caretaking of these patients. Objectives: This study is aimed to explain the perspectives and experiences among caregivers of the patients undergoing hemodialysis in Iran. Methods: A qualitative design, based on a thematic analysis approach, was used to reach the study aim. In this study, 25 hemodialysis family caregivers were selected by purposeful sampling. The data were gathered through in-depth and unstructured interview and field observation and analyzed by the inductive thematic approach. Results: The three main themes were generated from the analysis of the data indicating that the caregivers face challenges such as heavy burden of care, tension in care, and emotional exhaustion. Conclusion: Caretaking of the hemodialysis patients is constantly accompanied with challenges and concerns regarding the effective care for patients. Health-care providers need to address these concerns based on both patient- and caregiver-focused approaches, rather than only patient focused, to the design and planning for helping the patients and their caregivers.
