Objective To explore the effect of continued self-efficacy health education after discharge on patients with benign prostatic hyperplasia. Methods Toally 100 patients with benign prostatic hyperplasia during January to December 2015 were equally assigned to control group and observation group by random digit table:the former was treated with discharge instructions and the latter with discharge instruction plus self-efficacy health education. The two groups were compared before intervention and 6 weeks after intervention in terms of health behavior and self-management ability. Results Before intervention, there were no significant differences between the groups in health behavior and total score of self-management ability as well as the scores on its dimensions (P>0.05). After intervention, however, the total scores on health behavior and self-efficacy ability as well as the scores on the dimensions in the observation group were significantly higher than those of the control group (all P<0.01). Conclusion Post-discharge continued self-efficacy health education can be effective in improving their health behavior and self-management ability, which can promote their recovery.
