To evaluate the methodological quality and transparency of the clinical practice guidelines (CPGs) for the prevention, diagnosis, and treatment of gestational and congenital toxoplasmosis (CT).
Systematic review of the literature on gestational and CT CPGs conducted in the MEDLINE, Embase, TripDatabase, Biblioteca Virtual en Salud databases and extensive manual searches in 19 CPG repositories. The characteristics of each of the guidelines were extracted using My AGREE PLUS on-line. Three reviewers assessed overall quality using the Appraisal of Guidelines for Research and Evaluation II (AGREE II) tool.
The combined systematic review found 8651 citations. Of them 46 full texts were reviewed, and eight documents were finally included: four toxoplasmosis CPGs, three prenatal care CPGs that included recommendations on toxoplasmosis, and one pregnancy infection guideline that also included recommendations on toxoplasmosis. The AGREE II domains found to have the highest scores were ‘clarity of presentation’ (85%; [37%-100%]), followed by ‘scope and purpose’ (73%; [33%-98%]), and ‘editorial independence’ (51%; [3%-94%]); the domains with the lowest scores were ‘rigour of development’ (36%; [11%-79%]), ‘stakeholder involvement’ (34%; [24%-85%]), and ‘applicability’ (17%; [6%-83%]). The Colombian and Spanish-Agencia de Evaluación de Tecnologías Sanitarias de Andalucía (AETSA) CPGs had the highest global AGREE II scores. Absolute interrater agreement was good to excellent.
Substantial quality variation was found among CPGs, which provided recommendations in accordance with the context of the disease in the corresponding country or region. Only two of the CPGs appraised obtained a good score and are classified as ‘recommended’.
