This project aims to improve serum phosphate levels in patients, and to improve the attainment rates for serum phosphate goals in hemodialysis patients. An investigation calculated that the average monthly attainment rate for serum phosphate goals from July to November 2016 was 66.1%, which did not achieve the threshold value of 70% for serum phosphate goals set by our unit. We analyzed and established the following problems: forgetting to administer or carry medication, text-only nursing guidance leaflets, difficulty in remembering health education content, mistakes in medication administration, and preparation of food by caregivers. Auxiliary tools were used as an intervention measure to: (1) Improve nursing guidance leaflets; (2) Create health education posters on hyperphosphatemia; (3) Design dietary contraindication card for high phosphate-containing foods (4) Create colorful post-its; and (5) Create mobile medication boxes. After appropriate interventions, the average monthly attainment rate for serum phosphate goals was 73.2% from July to November 2017, and the general progress rate was 10.7%. Through creating and using auxiliary tools for cognitive restructuring and behavioral modification in patients so they can remind themselves to control the intake of phosphate-containing foods and increase medication compliance. This effectively decreased serum phosphate levels in patients, and thereby improved nursing care quality.
