简要总结
This study evaluates whether a risk-based perioperative pressure injury prevention bundle reduces the development of pressure injuries in patients undergoing elective surgery lasting 3 hours or longer.
Pressure injuries that develop during and after surgery are a common patient safety problem, especially in older adults and in longer procedures. In this randomized controlled trial, patients will be assigned by chance to either an intervention group or a control group. In the intervention group, each patient's pressure injury risk will be assessed before surgery using the Braden Scale together with additional perioperative risk factors, and patients will then receive one of three prevention bundles matched to their risk level (low, moderate, or high). The high-risk bundle includes prophylactic silicone foam dressings on the sacrum and heels, targeted positioning, and pressure-redistributing support surfaces. The control group will receive standard perioperative care without risk-based bundling, although Braden Scale assessment will still be performed.
Skin assessments will be conducted at four time points: before surgery, in the post-anesthesia care unit, at 2-4 hours after surgery, and at 24 hours after surgery. The main outcome is whether patients develop early signs of pressure injury, including non-blanchable erythema, within the first 24 postoperative hours. The study hypothesizes that patients receiving the risk-based prevention bundle will have a lower incidence of postoperative pressure injury and non-blanchable erythema compared with patients receiving standard care.
详细描述
This is a prospective, two-arm, parallel-group randomized controlled trial conducted according to the CONSORT 2025 guideline. Participants will be enrolled from orthopedic, general surgery, urology, and neurosurgery services at a single center. Block randomization with concealed allocation (sealed envelopes) will be used to assign participants to the intervention or control arm in a 1:1 ratio.
In the intervention arm, risk stratification will be based on the Braden Scale score combined with additional perioperative risk factors (e.g., surgical duration, ASA class, intraoperative hypotension or hypothermia, surgical position). Patients will be categorized into low-, moderate-, or high-risk subgroups, each receiving a distinct prevention bundle consisting of positioning strategies, support-surface selection, and, for high-risk patients, prophylactic silicone foam dressings.
Data will be collected using a study-specific instrument developed based on the 2025 EPUAP/NPIAP/PPPIA Pressure Injury Prevention Guideline, consisting of a demographic/clinical data section, the Braden Scale, a bundle-implementation checklist (intervention arm only), and a skin assessment outcome form completed at all four time points for both arms. Data will be analyzed using SPSS, with chi-square tests for categorical variables, independent-samples t-tests for continuous variables, and logistic regression to control for potential confounding by Braden score.

结局指标
主要结局
Incidence of Postoperative Pressure Injury
时间窗: Assessed at 24 hours after surgery (T3)
Development of a pressure injury (including non-blanchable erythema) at any assessed anatomical site (sacrum, right/left heel, occiput, scapula, elbow, right/left trochanter, right/left malleolus, or other site), assessed via skin examination and recorded as Yes/No.
次要结局
- Number of Anatomical Sites at Risk(Assessed at 24 hours after surgery (T3))
- Protocol Adherence(Assessed throughout the perioperative period, from preoperative (T0) through 24 hours postoperative (T3))
- Incidence of Non-Blanchable Erythema(Assessed preoperatively (T0), in the post-anesthesia care unit (T1), at 2-4 hours postoperative (T2), and at 24 hours postoperative (T3))
