Introduction:

Incontinence associated dermatitis is a major health problem that can compromise the health of sufferers and represents significant costs to the Health System. The Perineal Assessment Tool is the only instrument specifically designed to assess the risk of incontinence dermatitis.

Purpose:

It was the cross-cultural adaptation and analysis of the psychometric properties of the Spanish version of the Perineal Assessment Tool scale.

Methods:

An observational study design divided into three phases was used. In the first phase, a process of translation and cross-cultural adaptation of the scale was carried out. In the second phase, a pilot test (n=15) was carried out using a cross-sectional design to determine viability, intraobserver and interobserver reliability, and content validity of the Spanish version of the scale. Finally, in the third phase, a crosssectional study was performed using a sample of 171 patients to determine the prevalence of incontinence-associated dermatitis and to analyze the internal consistency, criterion and construct validity, sensitivity, specificity, positive and negative predictive value, as well as the cut-off points of the scale.

Results:

In the first phase, the Spanish version of the Perineal Assessment Tool proved to be feasible, manageable in less than 3 minutes, easy to understand and complete. In the second phase, the validity index of the overall content of the Spanish version of the Perineal Assessment Tool scale was 0.83, the intra-observer reliability was 0.98 and the inter-observer reliability was 0.99. In the third phase, the Spanish version of the Perineal Assessment Tool scale showed an internal consistency of 0.601 and a significant correlation with the humidity sections of the Braden and EMINA pressure ulcer risk assessment scales. The ROC curve was 0.959 and the best values were presented in a score of 7, showing a positive predictive value of 96.7%, a negative predictive value of %, a sensitivity of 74.4%, a specificity of 99.2% and, finally, an overall validity of 93.6%.

Conclusions:

The Spanish version of the Perineal Assessment Tool has proved to be a valid and reliable instrument for the evaluation of incontinence associated dermatitis in institutionalised patients in the Spanish context.
