Meta-analysis Investigating the Efficacy of Liquid Dressing and Ostomy Powder for the Treatment of Incontinence-Associated Dermatitis

OBJECTIVE: To study the effect of liquid dressing and ostomy powder on the treatment of incontinence-associated dermatitis (IAD). METHODS: The authors searched PubMed, Web of Science, CNKI (China National Knowledge Internet), and Google Scholar databases for literature through July 28, 2022. After literature screening, two investigators independently extracted data from the included studies and applied the Newcastle-Ottawa Scale to assess the quality of the included studies. The χ(2)-based Q statistic test and the I(2) statistic were used to measure the heterogeneity of the included studies. Publication bias was measured with funnel plots and the Egger test. Sensitivity analysis was conducted by eliminating each study one by one. RESULTS: Four high-quality studies were included in the meta-analysis, involving a total of 307 participants. The meta-analysis results showed that compared with traditional care, treatment with liquid dressing and ostomy powder significantly improved the effective rate (pooled odds ratio, 21.42; 95% CI, 8.58 to 53.44), shortened the healing time (pooled mean difference, −10.73; 95% CI, −12.92 to −8.54), and reduced the recurrence rate (pooled mean difference, −2.03; 95% CI, −2.30 to −1.77) of IAD. Among the included studies, no publication bias was detected. Sensitivity analysis results confirmed the robustness of the pooled estimates. CONCLUSIONS: Treatment with liquid dressing and ostomy powder has clinical value for patients with IAD.
