The incontinence-associated dermatitis and its severity instrument: development and validation.

Area of Science:

• Dermatology
• Nursing Research
• Clinical Assessment Tools

Background:

• Incontinence-associated dermatitis (IAD) is a common issue in healthcare settings.
• Accurate assessment of IAD severity is crucial for effective treatment and prevention.
• A validated and reliable instrument for IAD assessment was previously lacking.

Purpose of the Study:

• To develop a novel instrument for describing and measuring the severity of incontinence-associated dermatitis.
• To test the face, content, and criterion validity of the new instrument.
• To evaluate the interrater reliability of the Incontinence-Associated Dermatitis and its Severity Instrument.

Main Methods:

• Face and content validity were established through consultations with certified WOC nurse experts.
• Interrater reliability was assessed using data from WOCN Society conference attendees and healthcare employees.
• Criterion validity was determined by comparing instrument scores with expert assessments.

Main Results:

• The instrument demonstrated strong face and content validity.
• No significant differences in IAD severity scores were found among different tester groups.
• Excellent overall agreement (intraclass correlation = 0.98) was achieved between raters and experts.

Conclusions:

• The Incontinence-Associated Dermatitis and its Severity Instrument is a valid and reliable tool.
• The instrument addresses an unmet need in both clinical practice and research for IAD assessment.
• This tool can improve the consistency and accuracy of IAD evaluations.
