ObjectiveTo evaluate the quality of guidelines for the management of delirium in adult patients in the last ten years, so as to provide references for updating, selection, implementation guidelines and delirium management optimization.MethodsWe searched guidelines from databases including PubMed, EMbase, WanFang Data and CNKI, and websites of guidelines from January 1st 2010 to September 1st 2019. Guidelines were comprehensively screened, evaluated based on AGREE Ⅱ and data was independently extracted by two researchers.ResultsGuidelines of NICE, RNAO and SIGN had higher scores, while CSCCM’s and IPS’s gained lower. Among domains of AGREE Ⅱ, Domain I (scope and purpose) and IV (clarity of presentation) scored the highest, with a minimum of Domain Ⅱ (stakeholder involvement) and V (applicability). Delirium management focused on screening, prediction, prevention and treatment both pharmacologically and non-pharmacologically, and information support.ConclusionsFuture development of delirium guidelines should follow the methodology of guideline development, update or adjustment, and dedicate to every domain, especially domain of application. Medical staffs can establish our own domestic guidelines based on high quality guidelines, to promote knowledge translation and delirium management.
