Background: Hyperphosphatemia is common among haemodialysis patients and it leads to cardiovascular and renal bone disease. Assessment of KAP among haemodialysis patients towards phosphate control can be important in helping the healthcare professionals in educating patients and also improving patients` compliance to medical nutrition therapy in order to control the phosphate level.
Objective: To determine the association between Knowledge, Attitude and Practice (KAP) and hyperphosphatemia among haemodialysis patients.
Methods: A cross-sectional study was conducted on 105 haemodialysis patients in dialysis centre around Klang Valley. A set of questionnaire consisting of socio-demographic data, medical history and Knowledge, Attitude and Practice (KAP) questionnaire was used to interview the patients. Biochemical data was obtained through their medical record.
Results: The prevalence of hyperphosphatemia among haemodialysis patients was 53.0%. About 51.4% of the patients showed good KAP, 15.2% showed moderate KAP whereas 33.3% of the subjects demonstrated poor KAP towards phosphate control. Findings showed significant positive correlations between knowledge-attitude (r=0.460, p<0.001), knowledge-practice (r=0.571, p<0.001) and attitude-practice (r=0.321, p=0.001). However, there was no significant association between KAP and hyperphosphatemia (p>0.05). Education level and duration of haemodialysis were found to be significantly associated with KAP (p<0.05).
Conclusion: Majority of the subjects showed good KAP towards phosphate control, whereas there is no significant association between KAP and hyperphosphatemia. However, there is positive correlation between Knowledge and Attitude, Knowledge and Practice, Attitude and Practice. Results from present study showed that education level and duration of haemodialysis can affect KAP score.
