Incontinence-Associated Dermatitis: Are You Using the Right Skin Care?

"Break free from the confusion! Discover the key differences between moisture-associated skin damage and pressure injuries, and learn the best ways to protect sensitive skin."


Incontinence-associated dermatitis (IAD), also known as moisture-associated skin damage (MASD), is a common yet often misunderstood skin condition. It affects individuals of all ages, but is particularly prevalent among older adults and those with limited mobility. Characterized by inflammation, redness, and discomfort, IAD arises when the skin is exposed to prolonged wetness from urine or feces. This constant moisture disrupts the skin's natural barrier, making it vulnerable to irritation and infection.

The prevalence of IAD is significant, ranging from 5.6% to as high as 50% in some populations. What's more alarming is that the incidence rate can vary between 3.4% and 25%, underscoring the widespread nature of this condition. Despite its prevalence, IAD is frequently underestimated and improperly managed. This is often due to a lack of awareness regarding its implications and proper care protocols, highlighting the urgent need for enhanced knowledge and standardized preventative strategies.

This article aims to shed light on IAD, differentiating it from other skin conditions like pressure injuries, and equipping you with practical knowledge to protect vulnerable skin. Understanding the causes, implementing preventative measures, and applying appropriate treatments can significantly improve comfort, prevent complications, and enhance overall quality of life.

Comprehensive Prevention and Care

Incontinence-associated dermatitis (IAD) is an irritant contact dermatitis caused by chronic or repeated exposure to urine or feces. It is a form of moisture-associated skin damage that may present as poorly demarcated erythematous plaques on the perineum, buttocks, thighs, or groin. The 2023 practical guide recommends a comprehensive preventive care regimen, including daily care, to minimize IAD. Best-practice principles likewise define IAD as skin damage associated with exposure to urine or stool and describe it as irritant contact dermatitis.

What Exactly Is Incontinence-Associated Dermatitis?

IAD is defined as inflammation of the skin that occurs when urine or fecal matter comes into prolonged contact with the perineal or perigenital area. This condition is especially common in individuals who experience urinary or fecal incontinence, use absorbent pads or briefs, or spend extended periods in bed.

Several factors contribute to the development of IAD, including:

  • Frequency and type of incontinence: Whether it's urinary, fecal, or a combination, the frequency and nature of incontinence play a significant role.
  • Skin conditions: Pre-existing inflammation or edema can heighten vulnerability.
  • Compromised skin integrity: Factors such as humidity, pH imbalances, chemical components of urine or feces, and the presence of pathogens can further damage the skin's protective barrier.
  • Vulnerable populations: Older adults and individuals with neurological conditions are particularly susceptible, with women experiencing a higher prevalence.

Recent Reviews and Evidence

A November 2024 systematic review examined studies evaluating methods used to prevent and treat urinary incontinence-associated dermatitis. A July 2025 review focused on IAD in older adults and critically discussed current understanding of prevention and treatment, emphasizing methodologically high-quality systematic reviews and guidelines. That review also reports that frequent cleansing and occlusion from incontinence materials or prolonged lying or sitting can promote cutaneous inflammation and IAD development.

While accurately determining the exact prevalence and incidence of IAD is challenging due to limited scientific data, studies indicate that a substantial portion of incontinent individuals experience related perineal skin damage. Recognizing these factors is crucial for implementing targeted prevention and treatment strategies.

Key Takeaways for Managing and Preventing IAD

IAD can significantly impact an individual's well-being, highlighting the importance of early recognition, targeted prevention, and appropriate management. Healthcare providers, caregivers, and individuals experiencing incontinence must collaborate to implement effective strategies. These strategies should encompass thorough skin assessments, gentle cleansing practices, barrier protection, and prompt treatment of any developing skin damage. Continuous education, standardized care protocols, and open communication are crucial for minimizing the impact of IAD and improving quality of life.

Why Risk Varies

IAD is a prevalent and distressing form of irritant contact dermatitis associated with prolonged exposure to urine and/or faeces. However, the 2025 prognostic-factors research notes that not all incontinent individuals develop IAD, indicating that additional prognostic factors contribute to its onset. A 2017 review likewise describes IAD as irritant contact dermatitis associated with prolonged exposure of the skin to urine or feces.

Evolving Practice

The April 2026 international best-practice update identifies persistent barriers to optimal IAD management in everyday practice. Its objectives include identifying at-risk populations, implementing effective prevention strategies, accurately categorizing IAD, and selecting appropriate management approaches. A related 2026 practice document describes a significant evolution in how IAD is conceptualized, classified, and managed, while 2025 commentary emphasizes that IAD can occur in individuals of all ages and independently of diaper use.

What the comparisons do and do not establish

The two intervention comparisons point in the same direction: each reported a lower IAD measure in the intervention group than in its control group. They do not establish that the interventions are interchangeable or that either result applies across care settings.[1] [2]

The healing figure describes a result under standard treatment, not a comparison showing how much healing that regimen caused. The source itself frames the broader evidence on treatment effectiveness as limited.[3]

A critical review places incontinence prevalence among older adults in geriatric and long-term care settings at approximately 60–80%. This is a measure of incontinence, not IAD, so it describes the population context rather than the frequency of skin damage.[4]

A systematic review could not combine quantitative results in a meta-analysis because the studies differed in sample size, populations, designs, outcomes, timing, and analysis. Another review calls for higher-quality studies with larger groups and varied interventions, including pharmacological and non-pharmacological approaches; together, these reviews indicate that the available results are difficult to compare and synthesize.[5] [6]

What remains uncertain about IAD evidence

  • How much would estimates of IAD prevalence change if studies used more consistent definitions and diagnostic criteria?[4] [7]
  • Would intervention effects remain similar in larger studies with more consistent populations, outcome measures, and study methods?[5] [6]
  • How do urease-related changes in skin-surface pH and barrier properties contribute to IAD in real-world care, given that the evidence describes mechanisms rather than clinical outcomes?[4]
  • How does the combination of urine, bacteria, and stool enzymes relate to skin inflammation compared with urine exposure alone?[4]
