To compare pressure injury (PI) incidence based on repositioning intervals and support surfaces in acute care settings.
This pragmatic, quasi-experimental trial recruited a total of 251 critically ill patients who were at low or moderate risk for PI development. Participants were assigned to three interventions: a 2-hour repositioning interval using an air mattress, a 2-hour repositioning interval using a foam mattress, or a 3-hour repositioning interval using a foam mattress. Data were collected by nurses every shift over the course of 14 days. Pressure injury incidence was analyzed using a χ2 test.
There were no statistically significant differences in PI incidence between the groups with a 2-hour repositioning interval. However, the PI incidence in the group using a foam mattress with a 3-hour repositioning interval was significantly lower than in the group using an air mattress with a 2-hour repositioning interval (odds ratio, 0.481; 95% confidence interval, 0.410-0.565).
The findings showed that PIs decreased when the repositioning interval was extended from every 2 hours to every 3 hours while using foam mattresses. This study suggests that a 3-hour repositioning interval using a foam mattress could be applied to reduce the risk of PI development for patients at low or moderate risk.
比较急性护理环境中基于翻身间隔和支撑面的压力性损伤（PI）发生率。
这项实用、准实验性试验共招募了 251 名患有低度或中度 PI 风险的危重症患者。参与者被分配到三个干预组：使用空气床垫的 2 小时翻身间隔、使用泡沫床垫的 2 小时翻身间隔或使用泡沫床垫的 3 小时翻身间隔。护士每班次在 14 天内收集数据。使用 χ2 检验分析 PI 发生率。
在 2 小时翻身间隔组之间，PI 发生率无统计学差异。然而，使用泡沫床垫且 3 小时翻身间隔组的 PI 发生率明显低于使用空气床垫且 2 小时翻身间隔组（比值比，0.481；95%置信区间，0.410-0.565）。
研究结果表明，使用泡沫床垫时，将翻身间隔从每 2 小时延长至每 3 小时可降低 PI 发生率。本研究表明，对于低度或中度风险的患者，使用泡沫床垫且每 3 小时翻身一次可降低 PI 发生风险。
