Viewing an Educational Video Can Improve Phosphorus Control in Patients on Hemodialysis: a Pilot Study

Unlabelled: The objective of this single-arm interventional pilot study was to determine whether viewing an educational video about phosphorous and phosphorous control by patients on hemodialysis was associated with improved phosphorous values and improvement in knowledge and attitudes about the topics presented.

Method: An educational video was shown to 150 patients at 16 dialysis centers. The change in serum phosphate levels before and after the viewing of an educational video was evaluated.

Results: Mean phosphorous levels for patients were lower in the month after viewing the educational video compared to their values over the three months before the video was shown (6.35 versus 6.82 g/dL). This difference was statistically significant on a per patient basis (-0.47 g/dL, p = 0.0006). Of these patients, all with phosphorus levels outside of the normal range (3.5 to 5.5 mg/dL) before viewing the video, 28.4% had phosphorus levels within the normal range within a month after viewing the video.

Conclusion: Patients on hemodialysis who watched an educational video had improved phosphorous levels in the month after viewing the video when compared to phosphorus levels over the three months before the video was shown. The video intervention has the advantages of being simple, low-cost, and easy to implement, and is associated with improved phosphorous levels in patients undergoing hemodialysis. The video increased patient compliance with recommended self-care regimens.
