Diabetes mellitus (DM) is one of the most common metabolic and non-communicable disorders worldwide and the mortality rates caused by the complications associated with the disease, such as diabetic foot ulcer which is increasing dramatically. Foot ulcers are a significant complication, and the infected diabetic foot ulcers are a greater responsible for Amputations of the lower limbs that are not traumatic. Patient education is considered as an essential part of controlling and preventing foot complication of DM. To evaluate the effectiveness of self-management education program on prevention or and decreasing of diabetic foot ulcer severity and complications. The data before education were collected by using check list tool assessment for ulcer severity score and foot complications. Experimental group received self-management education based on health believe module (HBM), six sessions for the experimental group about foot complications and diabetic foot care education, the sessions comprised two hours per week for two month for each sub group which divided between seven to eight patient, the project followed up for three months to evaluate the effectiveness of education. We used verbal and visual patient education material. After education (Three months), the check list tool assessment used post administration education sessions. The data were analyzed using SPSS 25. A quasi experimental design was used to conduct this study, we enrolled 60 diabetic foot patients among type 2 DM. The participants were selected purposively assigned into two groups, experimental groups (who received the educational program) and a control group. Data were collected using Wagner classification score checklist and foot complication checklist that prepared by researcher depending on two academic book related foot complications , . A research collected the data by interviewing the participants using the checklist once before and once three month after the intervention. The participants of the intervention groups attended to education program consisting of one sessions two hours per week for two month. Statistical descriptive tests such as mean and standard deviation (SD) percentage were used to describe the features of the data inferential statistics test such as Chi-square and independent t-test were used as appropriate. The significance level was set at <0.05. The self-education management for diabetic foot patients showed decrease the severity ulcer score at (P < 0.000) and some foot complications like (fissures, nail lesion, infection, shoe bite, sharp injury and planter callus) in experimental group after three months follow-up. It can be concluded that self-management education depending on health Believe Module (HBM) is effective in preventing diabetic foot ulcer severity and preventing complications in diabetic patients.
