Abstract

Objective: To identify the accuracy of the Bayley III Scale to assess the neuropsychomotor development (DNPM) of children, as well as to identify the degree of evidence and the level of recommendation of the selected studies. Method: This is a systematic literature review using the keyword “Bayley III” in the Medline PubMed digital health database. The following filters were used: Clinical Trial, Controlled Clinical Trial, Meta-Analysis, Randomized Controlled Trial, Review, Scientific Integrity Review, Systematic Review. Studies published in English from January 2020 to November 2021 carried out in the neonatal and pediatric age group evaluated by the Bayley III Scale were included. The PICO method (P=patient; I=intervention; C=comparison; O=outcomes) was used to search for scientific articles in the digital health database, the degree of evidence and the level of recommendation were generated through of the GRADE rating. Results: 118 studies were found, 12 of which met the inclusion criteria of this study. Most studies (07) were classified as C evidence and low recommendation level, 02 of them were classified as D/very low, 02 as A/high and one of them as B/moderate. The age group included ranged from 6 to 36 months and 4 studies compared the accuracy of the BSID-III with the BSID-II. Conclusions: The Bayley III Scale has been widely applied in pediatrics to assess DNPM (cognitive, language, gross and fine motor) in the age group between one and 42 months corrected age. It has a mean sensitivity of 33.3% and specificity of 98%, with a level of evidence C and a low degree of recommendation to identify delays in DNPM in pediatrics.
