BackgroundPost-intensive care syndrome (PICS) seriously affects the quality of life of patients and their caregivers. This study systematically evaluates PICS related guidelines and consensuses to provide methodological and strategic guidance for the development and improvement of these guidelines and consensus.MethodsAn Internet search of PICS specific or related guidelines and consensus statements was conducted among academic databases and the websites. The AGREE II was used to evaluate their methodological quality. The themes and contents were evaluated based on the definition of PICS and the “patient-clinical problem-intervention-target” framework.ResultsWe included fourteen guidelines and 10 expert consensuses. The mean AGREE II score for scope and purpose was 86.89% ± 16.12%/ 79.47% ± 11.80%, 55.86% ± 29.17%/16.72% ± 16.39% for stakeholder involvement, 76.35% ± 15.82% /36.09% ±26.05% for rigor of development, 88.03% ± 15.55%/58.84% ± 28.94% for clarity of presentation, 61.79% ± 23.16/32.95% ± 20.91% for applicability, and 66.67% ± 37.96% /28.79% ± 36.54% for editorial independence in Guidelines/Consensus. Most only described a single or series of clinical related issues of PICS; only applicable for critically ill patients with clinical problems of ICUAW, pain, sleep disruption, agitation, and delirium. The interventions included risk assessment, monitoring/diagnosis, prevention, treatment, safety criteria, and home care of one or more symptoms of PICS.ConclusionsOur results suggested that development and improvement of guidelines/consensus should focus on refining the methodology, strengthening quality control, and improving presentation clarity, editorial independence, and applicability. The results may provide new idea for a future guidelines and consensus statements.
