Collection of efficacy indicators
infection, purulent
INFECTION, EPITHELIALIZATION
Though the wounds in this study were documented using digital photography and analyzed with image analysis software, factors such as environment, operational procedure, and patient positioning may influence the quality of the images. As such, a blinded assessment investigator should be assigned to document wound healing rates. Additionally, within this study, blinded investigators at the research center should determine the infection control rate, the score for quantitative TCM evidence, and the degree of epithelialization in wound healing. Prior to collecting these indicators, it is recommended that the following process and division of labor be adhered to (i) the treatment investigator and study nurse should remove all dressings, document any purulent discharge from the wound, and perform routine disinfection and cleaning of the wound; (ii) the study nurse should then notify the blinded evaluation investigator; and (iii) the blinded evaluator should proceed with the efficacy evaluation and capture the necessary photographs.
