this study aims to optimize the components of TIME CDST based on clinical practice and apply the optimized elements to the management of wounds with delayed healing risk after hip arthroplasty to identify and design the key steps in the clinical application of TIME CDST. Through a randomized controlled trial approach, the investigators will conduct a rigorous comparative analysis of the experimental group and the control group. The intervention group will receive an intervention plan based on the TIME CDST tool led by wound specialist nurses at each dressing change, while the control group receive a routine wound care program of wound cleaning and dressing changes at each dressing change. The main research objective is to evaluate the superiority of the experimental group compared with the control group in terms of wound healing time, healing quality, and patient satisfaction. Through the implementation of this study, the investigators expect to provide an effective optimization scheme for the management of postoperative wounds with delayed healing risk in clinical practice, thereby improving patient outcomes and quality of life.
1. Research Background and Objectives Orthopedic surgical wounds present more complex healing challenges compared to other surgical wounds. Hip arthroplasty is the most common type of orthopedic surgery. Due to surgical complexity or patient-specific factors, this procedure is particularly prone to surgical complications such as surgical site infection, wound dehiscence, tissue necrosis, and hematoma, thereby increasing the risk of delayed wound healing postoperatively.To improve the healing outcomes of postoperative wounds with delayed healing, optimizing nursing management protocols is crucial. This study aims to optimize nursing management for wounds with delayed healing risk after hip arthroplasty using the TIME CDST tool and validate its effectiveness. 2. Research Methods Study Design: This study employed a randomized controlled trial design, randomly assigning participants to an experimental group and a control group, which received different nursing management protocols. Sample Size: A total of 492 patients are expected to be included, with 246 in the experimental group and 246 in the control group. Intervention Measures: Patients in the experimental group will receive nursing management based on the TIME CDST tool, while those in the control group will receive conventional nursing management. Evaluation Indicators: The primary outcome measure is wound healing time. Secondary outcome measures include the number of cases with wound healing, wound area reduction rate, ASEPSIS wound scoring system, Stone-Brock Scar Scoring Scale (SBSES), Visual Analog Scale (VAS), patient comfort score, patient satisfaction score, albumin levels, dressing change frequency, and medical costs.Clinical adverse events will be recorded for safety assessment. Data collection and analysis: Data will be collected through questionnaire surveys, observation records, statistical analysis, and comparative analysis. 3. Study process Screening and grouping: Patients meeting the inclusion criteria will be screened and randomly assigned to the experimental group and control group. Intervention Implementation: The experimental group will receive a nursing management plan based on the TIME CDST tool, while the control group will receive routine nursing management. Follow-up and Evaluation: Regularly assess patients' wound conditions, record healing status, and collect patient satisfaction data. Data Analysis: Analyze the collected data and compare differences between the experimental group and the control group in terms of various assessment indicators. Result Interpretation and Report Writing: Based on the data analysis results, draw conclusions and write the research report. 4. Expected Results Through the implementation of this study, the researchers expect to draw the following conclusions: The nursing management plan based on the TIME CDST tool can significantly shorten the wound healing time after hip replacement surgery. This plan can improve the wound healing rate after hip replacement surgery. This plan can enhance patient satisfaction with nursing services. This plan has practical application and promotion value in clinical practice. 5. Significance and Value of the Study This study holds significant importance and value for optimizing nursing management of wounds with delayed healing risk. Through scientific experimental design and rigorous data analysis, researchers can provide effective nursing management strategies for clinical practice, thereby improving patient outcomes and quality of life. Additionally, the findings of this study can serve as a reference and inspiration for other similar studies, contributing to the advancement and development of the nursing management field.

A routine wound care program of wound cleaning and dressing changes
Wound healing time
Wound healing time will be assessed as the primary outcome indicator. Complete epithelialization of the wound is considered as wound healing and the time taken from enrollment to complete wound healing will be recorded for both groups.
Time frame: The time frame is from the date of intervention to the date of complete wound healing or the outcome endpoint, whichever comes first, with an assessment period of 6 months.
Number of cases with wound healing
The number of cases in which the wound will be completely epithelialized (defined as pink, non-exudative tissue completely covered by epithelium) during the period from enrollment to the endpoint
Time frame: The time frame is from the date of intervention to the date of complete wound healing or the outcome endpoint, whichever comes first, with an assessment period of 6 months.
The rate of wound area reduction
The rate of wound area reduction will be calculated through the following expression: (original wound area - present wound area)/original wound area × 100%. The accuracy of wound area measurements can be improved by placing a uniform wound measuring tape on one side of the wound and taking a picture of the wound area using image processing and analysis with Image J software (National Institutes of Health, Bethesda, MD).
Time frame: The time frame is from the date of intervention to the date of complete wound healing or the outcome endpoint, whichever comes first, with an assessment period of 6 months.
ASEPSIS wound scoring system
The ASEPSIS wound scoring system will be used to assess surgical wound infection and healing. This evaluation criteria primarily evaluates multiple aspects including wound characteristics, antibiotic use, wound drainage, local debridement, bacterial culture, hospital stay, and home care of the wound. A higher score indicates more severe wound infection. (Total score: 0 to 10 indicates satisfactory healing; 11 to 20 indicates poor healing; 21 to 30 indicates mild wound infection; 31 to 40 indicates moderate wound infection; and greater than 40 indicates severe wound infection.)
Time frame: The time frame is from the date of intervention to the date of complete wound healing or the outcome endpoint, whichever comes first, with an assessment period of 6 months.
Stony Brook Scar Evaluation Scale (SBSES)
The Stony Brook Scar Evaluation Scale (SBSES) will be measured the aesthetic outcome of postoperative wounds, including five criteria: width, height, color, suture line, and overall appearance. Each criterion is scored as 0 or 1, with a total score ranging from 0 (worst) to 5 (best)
Time frame: The time frame is from the date of intervention to the date of complete wound healing or the outcome endpoint, whichever comes first, with an assessment period of 6 months.
The pain intensity
The pain intensity is evaluated using the visual analogue scale (VAS). In the absence of pain, a score of 0 represents a painless state; a score of 1 to 3 represents mild pain; a score of 4 to 6 represents moderate pain; and a score of 7 to 10 represents severe pain.
Time frame: The time frame is from the date of intervention to the date of complete wound healing or the outcome endpoint, whichever comes first, with an assessment period of 6 months.
Patient comfort score
Use a self-made nursing comfort questionnaire to evaluate the patient's nursing comfort. The questionnaire was conducted on a 10 point scale, with scores\>9 indicating extreme comfort, 8-9 indicating relative comfort, 6-7 indicating basic comfort, and\<6 indicating discomfort.
Time frame: The time frame is from the date of intervention to the date of complete wound healing or the outcome endpoint, whichever comes first, with an assessment period of 6 months.
Patient satisfaction score
Use a self-made nursing satisfaction questionnaire to evaluate the patient's nursing satisfaction. Both questionnaires were conducted on a 10 point scale, with scores\>9 indicating very satisfied, 8-9 indicating relative satisfaction, 6-7 indicating basic satisfaction, and\<6 indicating dissatisfaction.
