Correction to: Prevention of radiation dermatitis with skin hygiene and washing: a systematic review and meta-analysis

Purpose This systematic review and meta-analysis aims to evaluate the effects of washing in patients receiving radiotherapy (RT) on radiation dermatitis (RD) severity. Methods A literature search was performed using Ovid MEDLINE, Embase, and Cochrane databases between January 1, 1946, and January 31, 2023. Four randomized controlled trials (RCTs) studying the effects of washing with or without soap on RD were identified. A meta-analysis was conducted for clinician-reported outcomes using RevMan 5.4 and a narrative synthesis for patient-reported outcomes due to a lack of reported data amenable to quantitative comparison in accordance with the Synthesis Without Meta-analysis (SWiM) guidelines. The Cochrane Risk of bias (RoB2) and Grading of Recommendations, Assessment, Development, and Evaluations (GRADE) criteria were used to assess risk of bias and certainty of evidence, respectively. Results Two RCTs met the inclusion criteria for meta-analysis. Washing with or without soap significantly reduced the incidence of severe RD (OR: 0.32, 95% CI: 0.19–0.55, p < 0.01) and moist desquamation (OR: 0.25, 95% CI: 0.12–0.52, p < 0.01). Two of four trials found an association between washing and reduced itching score ( p = 0.38). Pain score was not found to be significantly different with or without washing in any of the four studies ( p = 0.07). The two studies that assessed burn scores did not detect any difference between the washing group versus no washing group ( p = 0.25). Washing was associated with improved quality of life (QoL) measures in one study. Conclusion Washing with or without soap during RT resulted in less severe RD and less moist desquamation. Given the QoL benefits of washing, it should be advocated as part of routine skin care during RT.
