The goal of this study was to investigate the effect of an FCEP on hyperphosphatemia management in HPs. The results showed that FCEP could have a positive impact on the patients’ knowledge of phosphate control, adherence to DRPI, and adherence to medication as primary outcomes and on their serum phosphorus levels as the secondary outcome.Regarding the first research hypothesis, namely the effect of FCEP on knowledge of phosphate control, although we could not find any study on the effect of family-centered education on HPs’ knowledge, we found several studies showing that education and empowerment can improve the knowledge of patients with hyperphosphatemia. The study of Yin et al. for example showed that an intensive education program focused on phosphate control can improve HPs' phosphate control knowledge scores [In relation to the second hypothesis of this study, namely the effect of FCEP on adherence to DRPI, the literature contains several studies with findings similar to ours. In one of these studies, Montazami et al. reported that home visit-based FCEP can be an effective way to improve adherence to dietary and medication regimens in patients with acute coronary syndrome [Regarding the third hypothesis of the study, namely the effect of FCEP on adherence to medication, one study has shown that family-centered education is more effective than patient-centered education in improving HPs’ adherence to treatment and especially medication regimens [Concerning the fourth hypothesis of the study, namely the effect of FCEP on the secondary outcome, i.e. serum phosphorus level, the results of a study by Rabiei showed that FCEP could reduce the negative outcomes of CKD in patients [The present study is significant from these two perspectives. First, it focuses on the empowerment of not only HPs but also FCGs as people who play an essential role in the health promotion of these patients. Second, in addition to exploring the effect of FCEP on primary outcomes such as knowledge of phosphate control, adherence to DRPI, and adherence to medication, this study examines the effect of FCEP on the most important outcome for patients with hyperphosphatemia, i.e. serum phosphorus level.
