Abstract
Meta-analysis research was implemented to appraise the effect of various repositioning regimens (RRs) on pressure wound ulcer (PWU) occurrence in at-risk adult persons without existing PWUs. Inclusive literature research till April 2023 was done and 1197 interconnected researches were revised. The 15 picked researches, enclosed 8510 at-risk adult persons without existing PWUs persons were in the utilised researchers' starting point, 1002 of them were utilising repositioning, 1069 were control, 3443 were utilising 2-<4 h repositioning and 2994 were utilising 4-6 h repositioning. Odds ratio (OR) and 95% confidence intervals (CIs) were utilised to appraise the consequence of various RRs on PWU occurrence in at-risk adult persons without existing PWUs by the dichotomous approach and a fixed or random model. Repositioning had significantly lower PWU (OR, 0.49; 95% CI, 0.32-0.73, p < 0.001) compared to control in at-risk adult persons without existing PWUs persons. 2-<4 h repositioning had significantly lower PWU (OR, 0.62; 95% CI, 0.42-0.90, p = 0.01) compared to 4-6 h repositioning in at-risk adult persons without existing PWUs persons. Repositioning had significantly lower PWU compared to control in at-risk adult persons without existing PWU persons. 2-<4 h repositioning had significantly lower PWU compared to 4-6 h repositioning in at-risk adult persons without existing PWUs persons. However, caution needs to be taken when interacting with its values since there was a low sample size of some of the chosen research found for the comparisons in the meta-analysis.
