Objective To discuss the establishment,implementation and clinical effect of appraisal system of self-injection of insulin.Methods 100 type 2 diabetes patients were chosen as the objects.The appraisal system of self-injection of insulin for diabetes patients was established to quantify the level of related knowledge and self-injection level.Selective health education was given to patients and plan-imple-mentation-appraisal-processing(PDCA)method was adopted in the quality control management of health education.Results After the implementation of the appraisal system,the patients'grades of the related knowledge and skill on self-injection of insulin were enhanced.Fasting blood glucose and 2 h postprandial Mood glucose was stably controlled,which was statistically different from that before the implementation of the appraisal system.Conclusions The implementation of the appraisal system can sharpen the patients'self-control ability of disease and avoid the blindness,low efficiency and duplication of health education workers.
