Abstract: Objective: To identify evidence-based pressure injury prevention strategies for patients receiving prone position ventilation, and to assess their clinical outcomes. Methods: Guided by the "evidence-based continuous quality improvement model", evidence-based practice for pressure injury prevention in patients undergoing prone position ventilation was implemented from January to June 2023 following four stages, namely evidence acquisition, current status review, evidence introduction, and effect evaluation. Changes in nurses' compliance with audit indicators, the incidence of pressure injuries in patients undergoing prone position ventilation, and nurses' cognitive levels were assessed before and after evidence application. Results:A total of 26 pieces of evidence were finally included, and 20 audit indicators were developed. After the implementation of evidence-based practice, nurses' compliance with audit indicators and their knowledge and attitude levels related to pressure injury significantly improved (P<0.001). The incidence of pressure injuries in patients undergoing prone position ventilation decreased from 15.38% during the baseline audit to 6.67% (P< 0.05). Conclusion: Evidence-based practice measures can effectively improve nursing care quality for patients undergoing prone position ventilation, and enhance nurses' knowledge and attitudes regarding pressure injury.

摘要： 目的：探讨基于最佳证据的俯卧位通气患者压力性损伤预防措施，并评价其应用效果。方法：以“基于证据的持续质量改进模式”为指导，在 2023 年 1 月至 6 月期间，按照证据获取、现状审查、证据引入和效果评价 4 个阶段，将循证实践应用于俯卧位通气患者的压力性损伤预防。评估证据应用前后护士对审查指标的执行率、俯卧位通气患者压力性损伤发生率及护士认知水平的变化。结果：最终纳入 26 条证据，制定 20 条审查指标。证据应用后，护士对审查指标执行率及护士压力性损伤相关知识和态度水平明显提高（P<0.001）。俯卧位通气患者压力性损伤发生率从基线审查的 15.38% 下降至 6.67%。结论：基于证据的实践措施可有效改善俯卧位通气患者的护理质量，提高护士压力性损伤相关知识和态度水平。
