The methodological quality is insufficient in clinical practice guidelines in the context of COVID-19: Systematic review. Journal of Clinical Epidemiology, 135, 125-135. https://doi.org/10.1016/j.jclinepi.2021.03.005
Objectives: The number of published clinical practice guidelines related to COVID-19 has rapidly increased. This study explored if basic methodological standards of guideline development have been met in the published clinical practice guidelines related to COVID-19. Study Design and Setting: Rapid systematic review from February 1 until April 27, 2020 using MEDLINE [PubMed], CINAHL [Ebsco], Trip and manual search, including all types of healthcare workers providing any kind of healthcare to any patient population in any setting. Results: There were 1342 titles screened and 188 guidelines included. The highest average AGREE II domain score was 89% for scope and purpose , the lowest for rigor of development (25%). Only eight guidelines (4%) were based on a systematic literature search and a structured consensus process by representative experts (classified as the highest methodological quality). The majority (156; 83%) was solely built on an informal expert consensus. A process for regular updates was described in 27 guidelines (14%). Patients were included in the development of only one guideline. Conclusion: Despite clear scope, most publications fell short of basic methodological standards of guideline development. Clinicians should use guidelines that include up-to-date information, were informed by stakeholder involvement, and employed rigorous methodologies. (c) 2021 Medical University of Vienna.
