To verify whether amputation decision-making aids can alleviate the decisional dilemma in diabetic foot patients.
Through a clinical controlled study, the nurse-assisted intervention group utilized the Decision-Making Aid Tool for Amputation in Diabetic Foot Patientsto assess patients' treatment choice stages, provide disease-related knowledge, and clarify the advantages and disadvantages of different treatment options. This tool also helped patients articulate their values and preference biases. Subsequently, a questionnaire survey was conducted to evaluate decisional conflict, decisional expectations, and decisional satisfaction between the two groups, aiming to assess the tool's application efficacy.

| Experimental group | Active Comparator | In addition to receiving routine clinical consultations and nursing care identical to the control group, the intervention group will utilize an electronic decision-making aid for diabetic foot amputation. We will design this electronic tool and deliver it to participants via a WeChat Mini Program. Patients will be instructed to spend no more than 60 minutes using the tool, with researchers supervising their sessions and providing assistance as needed. During the study period, the electronic decision-making aid will remain confidential and accessible only to the intervention group, with restricted access for physicians and non-intervention patients. |

| The Satisfaction with Decision Scale，SWD | The scale consists of 6 items, allowing decision-makers to select the hospital description that best aligns with their individual circumstances. | Three days post-surgery ；One month postoperatively |
| Decision Regret Scale,DRS | The scale consists of 5 items rated using a Likert 5-point rating scale, with responses ranging from "Strongly Agree" to "Strongly Disagree" assigned scores of 1 to 5 respectively. Items 2 and 4 are reverse-coded. The total score is calculated by converting the mean score of all items using the formula: Total Score = (Mean Score - 1) × 5 This results in a total score range of 0-20 points, where higher scores indicate greater decision regret | Three days post-surgery；One month postoperatively |
