QUALITY APPRAISAL OF CLINICAL PRACTICE GUIDELINES ON PROVISION OF DENTAL SERVICES DURING THE FIRST MONTHS OF THE COVID-19 PANDEMIC

OBJECTIVES: To evaluate the quality of clinical practice guidelines (CPGs) on dental services provision during the first months of the COVID-19 pandemic. MATERIALS AND METHODS: We systematically searched in MEDLINE, EMBASE, LILACS, Epistemonikos, Trip databases, websites of CPG developers, compilers of CPGs, scientific societies and ministries of health to identify documents with recommendations intended to minimize the risk of COVID-19 transmission during dental care. Reviewers independently and in duplicate assessed the included CPGs using the AGREE II instrument. We calculated the standardized scores for the 6 domains and made a final recommendation about each CPG. The inter-appraiser agreement was assessed using the intraclass correlation coefficient (ICC). RESULTS: Twenty-three CPGs published were included. Most of the CPGs were from America (n = 15) and Europe (n = 6). The overall agreement between reviewers was very good (ICC = 0.93; 95%CI 0.87-0.95). The median score for each domain was the following: Scope and purpose 67% (IQR 20%); Stakeholder involvement 33% (IQR 14%); Rigour of development 13% (IQR 13%); Clarity of presentation 64% (IQR 31%); Applicability 19% (IQR 17%) and Editorial independence 8% (IQR 8%). Twenty two guidelines were not recommended by the reviewers. Only one of the CPGs was recommended with modifications. The median overall rate was 3 (IQR 1). All CPGs were classified as low quality. CONCLUSIONS: The overall quality of CPGs on dental services provision during the first months of the COVID-19 pandemic was low, which makes its implementation difficult for clinicians and policy makers. Therefore, it is critical that developers are transparent and forthcoming about the difficulties that have arisen during the CPG development process.
