Moisture lesions: interrater agreement and reliability.
OBJECTIVE
The aim of this study was to examine interrater reliability and agreement of the diagnosis of moisture lesions as defined by the European Pressure Ulcer Advisory Panel.


BACKGROUND
Differentiation between superficial pressure ulcers and moisture-related skin damages is difficult. To enhance the precision of the identification of moisture lesions, the European Pressure Ulcer Advisory Panel provided wound- and patient-related characteristics. Empirical evidence regarding interrater reliability and agreement among nurses for the detection of moisture-related skin damages in clinical practice is lacking.


METHODS
Observational.


METHODS
Home care clients (n = 339) were independently assessed twice by trained nurses. A head to toe skin inspection was conducted.


RESULTS
For the diagnosis of moisture lesion (yes/no), nurses exactly agreed in 95% of all assessed clients. Interrater reliability was intraclass correlation coefficient (1,1) = 0.67 (95% CI 0.61-0.73).


CONCLUSIONS
Nurses were able to differentiate between home care clients with and without moisture lesions but assessment results contained a high degree of measurement error. It seems that the descriptions for the identification of moisture lesions provided by the European Pressure Ulcer Advisory Panel do support the diagnostic process but reliability must be enhanced.


CONCLUSIONS
Because of low interrater reliability, it is questionable whether the diagnosis of moisture lesions in clinical practice is valid. Measurement error is too high to make adequate inferences for individuals. Definitions and descriptions provided by the European Pressure Ulcer Advisory Panel, provisions of a single training and images are not sufficient to achieve acceptable interrater reliability in clinical practice.
