Morphological characteristics of and factors related to moisture-associated dermatitis surrounding malignant wounds in breast cancer patients

PurposePatients with malignant breast wounds (MBWs) have multiple symptoms. In particular, care for exudates or peri-wound moisture-associated dermatitis (MAD) is difficult. However, MAD has not been distinguished from peri-wound dermatitis. Therefore, care for patients with MAD has not been well established. The aim of this study was to describe morphological characteristics of MAD in MBWs and link morphological characteristics of MAD to related factors.MethodsWe conducted a qualitative descriptive study and a cross-sectional study. Data were collected by qualitative participant observation and structured interviews. The qualitative descriptive study was conducted using the ‘morphoqualitative analysis’ method. Data analyses were performed using qualitative research methods. In the cross-sectional study, the participants were classified into 2 groups for comparison: with MAD (MAD group) and without MAD (non-MAD group).ResultsCharacteristics of 24 MBWs were examined. Morphoqualitative analyses of data generated 17 subcategories and 3 categories. We could morphologically define MAD by findings of ‘radial shape matching the dressing’ and ‘half-fusiform shape over the dressing’. Regarding factors related to MAD, necrotic tissue type was significantly more severe in the MAD group than in the non-MAD group (p = 0.048). Wound exudate leakage was significantly more frequent in the MAD group than in the non-MAD group (p = 0.013).ConclusionOur study provides several points for nursing MBWs. Morphoqualitative analyses of MAD are quite important for evaluating possible causes of MAD as well as selecting effective interventions.
