Assessment tools for chronic wounds, such as pressure sores, are available, but
a wound assessment tool specifically for diabetic wounds has not been
The purpose of this study was to determine the critical cutoff point for
classifying wound healing.
A retrospective cohort study design with a convenience sample of 75 diabetic
foot ulcer patients enrolled from a Kitamura Wound Clinic from February
2015 - January 2016. The inconsistency of wound healing assessment data was
not included in this study. The MUNGS score and skin assessment were rated.
The diabetic ulcer patients were observed every ten days until healing or
discharge. A mean score of MUNGS assessment each patients were calculated.
Seventy-five diabetic ulcer patients were collected. The MUNGS tool has an
area under the ROC curve (AUC) 0.886, and the 95% confidence interval was
0.792 to 0.948. At a cutoff score of 4, the sensitivity was 84.91, and the
specificity was 81.82, positive predictive value of (91.8) and negative predictive
value of (69.2), with likelihood ratio was 4.67 respectively.
The value of the MUNGS tool in this study showed excellent accuracy in the
mean score assessment. An accurate wound assessment is essential to the
appropriate and realistic planning of goals and Interventions for patients with
