This project aimed to improve the interdialytic weight control of our patients on chronic hemodialysis. Large interdialytic weight gain, defined as greater than 5% of the dry weight, was recorded in 58.9% of our patients who had been dialyzed for more than one year. Factors included poor educational skills in nursing personnel, inadequate knowledge of patients, no standard procedure on education, impractical health education pamphlet, and physiological factors relating to patient thirst. Based on these factors, we planned laid out a strategy that included teaching program for nurses, group education for patients, development of a fluid control tool, and rephrasing of the fluid control pamphlet. Upon implementation the percentage of patients with large interdialytic weight gain dropped to 25%. The results show significant benefits from this project as it not only solved the patient problem but also improved the quality of nursing.
