BACKGROUND: Incontinence-associated dermatitis is common among older adults in intensive and semi-intensive care units. Impaired consciousness, incontinence, and limited self-care increase the risk of severe skin damage, negatively affecting physical, psychological, and social well-being.
AIM: We compared incontinence-associated dermatitis risk, severity, skin surface pH (a measure of acidity/alkalinity), and skin moisture between the control and experimental groups.
DESIGN: Double blind block-randomized controlled trial, two groups pre-posttest design.
METHODS: Participants were randomly assigned to either the control or experimental group. Both participants and outcome assessors were blinded to group allocation. The control group (n = 30) received a structured nursing care program for incontinence-associated dermatitis prevention and management combined with zinc oxide mixed with petroleum jelly. The experimental group (n = 30) received the same nursing care program combined with an herbal formulation of Centella asiatica and Aloe vera. The intervention lasted 7 days. Outcomes measured included compared incontinence-associated dermatitis risk, severity, skin surface pH, and skin moisture.
RESULTS: The two groups differed significantly (p < 0.001), with the experimental group demonstrating significantly lower risk scores than the control group. Similarly, the severity of incontinence-associated dermatitis was significantly lower in the experimental group (p < 0.001). Skin pH levels were significantly reduced in the experimental group (p < 0.001), indicating a more favorable acidic balance. In addition, skin moisture levels were significantly higher in the experimental group compared to the control group (p < 0.001).
CONCLUSION: A structured nursing care program combined with an herbal formulation of Centella asiatica and Aloe vera effectively reduced the risk and severity of incontinence-associated dermatitis in older adults. Furthermore, the intervention helped maintain optimal skin pH within a mildly acidic range and significantly improved and preserved skin moisture.
IMPACT: We have provided evidence that a structured nursing care program combined with an herbal-based skin protectant (Centella asiatica and Aloe vera) effectively reduced the risk and severity of incontinence-associated dermatitis in older adults. The intervention improved key skin health indicators, including skin pH balance and moisture, supporting skin integrity and healing. These findings can inform clinical practice by guiding evidence-based incontinence-associated dermatitis prevention and management and by suggesting a cost-effective, accessible approach to improving outcomes in aging populations.
PATIENT AND PUBLIC CONTRIBUTION: Patients and caregivers participated by providing informed consent and supporting intervention implementation. Nursing provided interventions to patients, and a medical doctor conducted the allergic screening and outcome verification.
