Existing IAD instruments are too time-consuming and linguistically complex for use in routine clinical practice in nursing homes. We found that staff generally found the SSS easy to judge IAD severity based on pictures used in the study. This finding suggests that the SSS could be improved by adding reference photographs of skin illustrating each of the 4 points on the scale. Such an instrument could be designed and validated with an emphasis on integration into current clinical practice pathways.
