Classification of pressure injury stages and skin damage photographs by RNs and nursing students in Spain. An observational comparison study

Abstract

[eng]PURPOSE: The purpose of this study was to evaluate and classify pressure injuries (PIs) and other skin lesions according to the judgment of hospital-based RNs and nursing students who recently trained in wound care using photographs and comparing findings to those of wound care experts. DESIGN: Cross-sectional observational survey. SUBJECT AND SETTING: RNs working at Manacor Hospital, Mallorca, Spain, and third-year nursing students from the University of the Balearic Islands. Data were collected in June 2017. METHODS: The survey instrument was accompanied by a set of 24 photographs in 7 categories of skin lesions, such as PIs or moisture-associated skin damage, which the respondents were asked to classify. Descriptive analysis of the classifications was carried out, and levels of agreement using the chi-square test were compared with evaluations/classifications of a panel of experts. RESULTS: In total, 314 surveys (199 RNs and 115 students) were included in the analyses. Findings showed a wide variability among participants with levels of agreement, with expert opinion ranging from 91.4% to 15.61%. The levels of agreement were substantially lower for unstageable PIs (47.92%), those caused by moisture (53.50%), and mixed etiology (38.37%) than for stages 1-4 PIs. Of note, 62.12% of RNs had not received PI training or continuing education during the previous 2 years. This lack of education was statistically significantly associated with the accuracy of the classification made by the RNs for some of the photographs evaluated such as moisture-associated skin damage. CONCLUSIONS: We found discrepancies in the classification of PIs and other wounds/lesions among experts, RNs, and students. The regular provision of up-to-date information in training and continuing education programs is imperative to maintain nurses' abilities to identify and classify PIs and other skin-related damage.
