Abstract: Objective: To evaluate the effect of systematic training on improving nurses' knowledge and attitudes towards common complications among bedridden patients and decreasing the incidence of patients' complications. Methods: Nurses were recruited from 25 different grade hospitals and received systemtic nursing training about common complications(including pressure ulcer, Deep Vein Thrombosis, pneumonia, and urinary tract infections) among bedridden patients. The training content were developed by systematic literature review and expert discussion. Training SOP (Standard Operating Procedure) was developed and lectures, pocket books and online learning platform were used to train the nurses. Totally 3 903 nurses were recruited in the study as control group before the training program while 4 043 nurses were recruited as experimental group. Nurses' knowledge and attitudes and incidence of patient complications were measured to evaluate the training effects. Results: After systematic training, nurses' knowledge scores for all 4 complications were significantly increased (P<0.05), while the attitudes scores for Deep Vein Thrombosis, pneumonia, and urinary tract infections were also significantly improved (P<0.05). The incidence of pressure ulcer, pneumonia, and urinary tract infections were also decreased after training. Conclusion: The systematic training is an effective way to improve nurses' knowledge and attitudes and reduce the incidence of common complications among bedridden patients. It is worth for further popularization and application.
