A multidisciplinary Delphi consensus to define evidence-based quality indicators for diabetic foot ulcer care

Abstract Background Valid measures to assess quality of care delivered to patients with diabetes suffering from diabetic foot ulcer (DFU) are scarce. This study aimed to achieve consensus on relevant and feasible quality indicators (QIs) among stakeholders involved in DFU care and was conducted as the second part of a Belgian QI selection study that sought to identify QIs for DFU care. Methods A stakeholder panel, including caregivers from primary care and specialized disciplines active in diabetic foot care as well as a patient organization representative, was recruited. By using the RAND/UCLA Appropriateness Method, stakeholders were asked to rate a list of 42 candidate evidence-based indicators for appropriateness through a 9-point Likert scale. QIs were classified based on the median ratings and the disagreement index, calculated by the inter-percentile range adjusted for symmetry. Results At the end of a three-phase process, 17 QIs were judged as appropriate. Among them, five were not previously described, covering the following topics: integration of wound care specialty in the multidisciplinary team, systematic evaluation of the nutritional status of the patient, administration of low-density lipoprotein-cholesterol lowering medication and protocolized care (implementation of care and prevention management protocols). Conclusions The identified evidence-based QIs provide an assessment tool to evaluate and monitor quality of care delivered to DFU patients. Future research should focus on their complementarity with the existing QIs and their implementation in clinical practice.
