The study was a quasi-experimental design (quasi experiment), under the design of the separate pretest-posttest-sample control group design, involving two groups: the intervention group and the control group. Nursing care has a significant role to gangrenous wound healing in diabetic patients at Dr. Pirngadi General Hospital Medan. This is indicated by the role or influence of the sixth variables of nursing care consisting of diet, physical exercise, wound care, insulin administration, psychological factors, social factors, and wound healing with the value of the odds ratio greater than 1.Based on the multivariate analysis, the value of the role of nursing care to the gangrenous wound healing in diabetic patients is at 0410 x 100% = 41.0%. Gangrenous wound nursing care in patients with diabetes mellitus showed a significant effect with a significance value of 0.001, less than the sig- (0.05). This means that the six independent variables simultaneously bring significant influence on the dependent variable (gangrenous wound healing).
