Clinical practice guidelines on nutrition management in head and neck cancer: a systematic quality appraisal using the Appraisal of Guidelines for Research and Evaluation 2nd edition instrument

Abstract

AbstractObjectiveSeveral guidelines have been produced for the management of nutrition in patients with head and neck cancer. However, no systematic evaluation of the quality of these guidelines has been performed to date.MethodA comprehensive search was conducted up to August 2020. The quality of guidelines was assessed by four independent reviewers using the Appraisal of Guidelines for Research and Evaluation, 2nd edition.ResultsNine guidelines were assessed for critical evaluation. Only two guidelines were classified as ‘high quality’. The ‘scope and purpose’ domain achieved the highest mean score (75.5 ± 17.0 per cent), and the lowest domain mean score was ‘applicability’ (37.6 ± 23.0 per cent).ConclusionThese findings highlight the variability in the methodological quality of guidelines for the management of nutrition in head and neck cancer. These results may help to improve the reporting of future guidelines and guide the selection for use in clinical practice.
