Objectives To investigate the clinical efficacy of health education intervention on chronic gastritis nursing. Methods A total of 142 patients with chronic gastritis in our hospital were recruited from February 2016 to June 2017. All patients were randomly assigned into two groups. The control group received conventional therapy and routine nursing, whereas the case group was offered with extra health education based on control group. Then related disease knowledge, nursing efficiency, nursing satisfaction, and nursing quality were compared. Results A total of 71 patients were in the case group, while 71 patients in the control group. Compared with the control group, the case group achieved better related disease knowledge, nursing satisfaction, total nursing efficiency, psychological status, sleep quality, exercise training, and daily diet (all P value<0.05). Conclusions Health education intervention not only can enhance disease knowledge of patients with chronic gastritis but also improve nursing quality, clinical effects and nursing satisfaction. Thus, it is worthy of further popularization in clinics.
