Abstract

Background: Nonadherence to hand hygiene and aseptic regimen, dialysis environment guidelines, and catheter and exit-site care guidelines are risk factors of peritonitis. However, little is known about the psychosocial factors that account for the nonadherent behavior of patients undergoing peritoneal dialysis (PD). Applying the health belief model, this study seeks to enhance the understanding of psychosocial influences on patients' nonadherent behavior to the 3 regimen components. Methods: Through referrals by 7 Hong Kong renal patient support groups, we surveyed patients undergoing PD treatment. Results: A total of 244 Hong Kong PD patients completed the questionnaires. About 90% of the patients reported no deviation from catheter and exit-site care guidelines. However, the nonadherence rates of hand hygiene and aseptic regimen and of dialysis environment guidelines were 30.3% and 23%, respectively. Longer time on PD treatment and lower family monthly income were associated with nonadherence to dialysis environment guidelines. Employed patients tended toward nonadherence to catheter and exit-site care guidelines twice as much as unemployed patients. Of the 5 health beliefs, perceived benefits, perceived barriers, and efficacy belief were significant predictors of nonadherence to the 3 regimen components. Conclusions: The findings of this study inform the design of intervention to change patients' behavior in regimen nonadherence for preventing peritonitis. To identify the target audience for adherence intervention based on the 3 regimen components, the results suggest dividing patients into subgroups according to their sociodemographic background. To foster behavioral change, health communicators should address patients' health beliefs when formulating intervention strategies.
