Prevention, assessment, diagnosis and management of diabetic foot based on clinical practice guidelines: A systematic review

AIM: Diabetic foot complications are the main reason for hospitalization and amputation in people with diabetes and have a prevalence of up to 25%. Clinical practice guidelines are recommendations based on evidence with the aim of improving health care. The main aim of this study was to carry out a systematic review of the levels of the evaluation and treatment strategies that appear in the clinical practice guidelines focus on diabetic foot or diabetes with diabetic foot section. Another objective of this study was to perform an analysis of the levels of evidence in support of the recommendations made by the selected clinical practice guidelines. METHODS: A systematic review according to the Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) and a quality assessment by the Appraisal of Guidelines for Research and Evaluation (AGREE II) were performed. The databases checked were “NICE”, “Cinahl”, “Health Guide”, “RNAO”, “Sign”, “PubMed”, “Scopus” and “NCG”. The search terms included were “diabetic foot”, “guideline(s)”, “practice guideline(s)” and “diabetes.” RESULTS: Twelve articles were selected after checked inclusion criteria and quality assessment. A summary and classification of the recommendations was completed. CONCLUSIONS: The heterogeneity of levels of evidence and grades of recommendation of the CPGs included regarding the management, approach and treatment of DF makes it difficult to interpret and assume them in clinical practice in order to select the most correct procedures. Despite this and according to the detailed study of the guidelines included in this work, it can be concluded that the highly recommendable interventions for DF management are debridement (very high level of evidence and strongly recommended), foot evaluation (moderate level of evidence and fairly recommended) and therapeutic footwear (moderate level of evidence and fairly recommended).
