effectiveness of the professional collaboration of care-centered model (pccc) on the knowledge of patients with hepatitis b regarding preventive behaviors

background education is crucial to improve the preventive behaviors of patients with hepatitis b. the professional collaboration of care-centered model (pccc) is one novel educational model that has shown promising effects in recent studies. objectives thus, this study aimed to assess the effects of patient education based on pccc on the knowledge of patients with hepatitis b regarding preventive behaviors. methods this randomized clinical trial study was conducted on 50 patients with hepatitis b in ahvaz imam and razi hospitals in iran during 2014. patients were randomly divided into two groups: an intervention (n = 25) and a control (n = 25) group. first, patients in both groups completed a demographical and clinical checklist as well as a knowledge questionnaire. patients in the control group received routine education, while patients in the intervention group were educated based on pccc for 4 sessions. at the end of the 4-week intervention, patients completed the questionnaires again. data were analyzed by spss version 22 using student’s t test and the chi-squared test. conclusions regarding our results, education based on the pccc model could be effective in improving knowledge in patients with hepatitis b. thus, it is recommended that this model be used as a simple method to improve preventive behaviors. results before the intervention, there were no significant differences between the two groups (p = 0.133), while after the intervention a significant difference was seen between the two groups, favoring the intervention group based on the increased mean score (p < 0.001). in addition, a significant difference was observed between the intervention group’s pre and post scores (p < 0.001), while no significant difference was seen in the control group (p = 0.56).
