BackgroundChronic wounds are an increasing problem in the aging population, patients experience a lower health-related quality of life and the care for these patients is associated with high costs. Thorough wound assessments facilitate objective monitoring of wound status and progress. A wound assessment tool can guide clinicians in these wound assessments and in recording wound progress or deterioration.ObjectiveSystematically identify assessment tools for chronic wounds, investigate their measurement properties, and summarize the data per assessment tool.DesignSystematic review METHODS: The databases Medline (PubMed interface), Embase, CINAHL, and CENTRAL were systematically searched until May 2020 (updated in February 2021). Studies reporting the development and/or the evaluation of measurement properties of assessment tools for chronic wounds were included. The "Consensus-based Standards for the selection of health Measurement Instruments" risk of Bias checklist was applied to evaluate the methodological quality of the included studies. Each reported measurement property was rated against criteria for good measurement properties. The evidence was summarized and the quality of the evidence was graded using a modified Grades of Recommendation, Assessment, Development, and Evaluation approach. Study selection, data extraction and quality appraisal were conducted independently by two reviewers and double-checked by a third reviewer.ResultsTwenty-seven studies describing the measurement properties of fourteen assessment tools for chronic wounds were included. None of the studies reported a content validity evaluation by a relevance study or a comprehensiveness study in professionals. Six articles reported the development or revision of an existing assessment tool. The reported measurement properties included: structural validity (5 studies), reliability (18 studies), hypotheses testing for construct validity (18 studies) and responsiveness (7 studies). Internal consistency, cross-cultural validity / measurement invariance and measurement error were not reported. If criterion validity was assessed, the results were allocated to hypotheses testing for construct validity as no 'gold standard' is available.ConclusionsFourteen assessment tools for chronic wounds were identified. Construct validity (by hypotheses testing) and responsiveness of the Pressure Ulcer Scale for Healing version 3.0 were supported by sufficient ratings based on moderate to high level quality of evidence. Reliability of the (Revised) Photographic Wound Assessment Tool had a sufficient rating based on moderate quality of evidence. The ratings of the measurement properties of the other wound assessment tools were either insufficient or indeterminate, or a sufficient result was supported by low to very low quality of evidence.
