Influence of Sociodemographic Factors and Incontinence Care Practices on the Development of Incontinence-Associated Dermatitis

<b>Objectives:</b> The general objective of the study was to analyze the influence of sociodemographic factors and care and hygiene practices on the appearance of Incontinence-Associated Dermatitis (IAD). The specific objectives were to identify the relationship between sociodemographic variables (age, sex, comorbidities) and the incidence of IAD, and to evaluate hygiene protocols (cleaning products and absorbent use and practices) and compare time to IAD onset according to the hygiene practices used. <b>Methods:</b> A multicenter, prospective cohort study was conducted across 10 social health centers. The study population consisted of older institutionalized patients with urinary and/or mixed incontinence who used absorbents continuously. The variables included risk assessment using validated scales, such as the Braden scale and the Perianal Assessment Tool (PAT), as well as ad hoc questionnaires. Survival analysis of time-to-event onset was assessed using the Kaplan-Meier curve and the Log-Rank test. <b>Results</b>: A statistically significant association was found between the occurrence of IAD and the Braden scale (<i>p</i> = 0.004) and the PAT scale (<i>p</i> = 0.02). However, no statistically significant association was found with age, sex, or the Barthel Index. Regarding hygiene, soapy wipes were associated with the highest incidence of IAD. In contrast, dry wipes were the most effective, with the lowest cumulative risk and the longest time-to-event (<i>p</i> = 0.001). The brand of the absorbent used had a significant influence (<i>p</i> = 0.024), suggesting that the "B" brand prevented one IAD per six patients compared with the "A" brand. The frequency of absorbent changes did not show a statistically significant association. <b>Conclusions:</b> The risk of developing IAD was strongly linked to the scores of the Braden and PAT scales, the brand of the absorbent ("B" being more effective), and the cleaning product used, with dry wipes being the most protective compared to soapy wipes. On the other hand, factors such as age, sex, degree of dependence (Barthel), or frequency of absorbent change did not show a significant influence on the appearance of IAD.
