A new diabetic foot evaluation scale was proposed, using the seven domains of depth, maceration, inflammation/infection, size, tissue type of the wound bed, type of wound edge, and tunneling/undermining. This scale was named "DMIST" as an acronym from the initials of the domains. The purpose of this study was to evaluate the validity of DMIST. Secondary analysis was conducted in three investigations performed using the diabetic foot ulcer assessment scale (DFUAS) in Japan and Indonesia. Secondary analysis was assessed using DMIST, PUSH and DESIGN for 4 weeks based on DFUAS score and photos of diabetic foot ulcers by researchers. Concurrent validity was determined from the correlation of total DMIST scores with PUSH and DESIGN scores. Construct validity was determined by comparisons between total DMIST score and grade of the Wagner classification. Predictive validity was determined by receiver operating characteristic curve analysis for wound non-healing 4 weeks later. Subjects comprised 35 Japanese patients and 118 Indonesian patients. Correlations of total DMIST score with PUSH and DESIGN scores were 0.831 and 0.822, respectively. Comparison of total DMIST scores with grade of the Wagner classification (Grade I vs Grade II/III vs Grade IV/V) was P < 0.001. Based on an area under the curve of 0.872, a DMIST score of 9 was selected as a cut-off, offering sensitivity of 0.855 and specificity of 0.786 for wound non-healing 4 weeks later. Our findings suggest that DMIST offers high validity

Relationship between items of DMIST and healing of diabetic foot ulcers

A monitoring tool for the wound-healing process of diabetic foot ulcers (DFUs) was developed. It comprises seven domains, namely, depth, maceration, inflammation/infection, size, tissue type of the wound bed, type of wound edge, and tunnelling/undermining. It was named "DMIST" based on the initials of its domains. Although DMIST is useful for assessing wound-healing processes, the monitoring items related to wound healing remain unclear, thereby making the selection of optimal care based on the assessment difficult. We identified the relationship between the DMIST items and wound healing. This study was a secondary analysis of five previous investigations and was conducted using DMIST based on the diabetic foot ulcer assessment scale score and DFU images. Multivariate logistic regression was used to calculate odds ratios (ORs) and 95% confidence intervals (95% CIs) after simultaneously controlling for potential confounders. The examined DFU healing status revealed that some DFUs healed at 4 weeks from baseline, whereas some DFUs did not. Variables considered in the models were the scores of each DMIST domain. The study population comprised 146 Indonesian patients and 33 Japanese patients. Depth, maceration, and size were associated with DFU healing at 4 weeks from baseline [depth: OR = 0.317 (95% CI: 0.145-0.693, P = 0.004); maceration: OR = 0.445 (95% CI: 0.221-0.896, P = 0.023); size: OR = 0.623 (95% CI: 0.451-0.862, P = 0.004)]. Our findings suggest that appropriate management of maceration promotes DFU healing.
