Background:

Early childhood development is a complex process that requires reliable tools for the timely detection of alterations that may affect a child’s progress. The Child Development Evaluation test (EDI, in its Spanish acronym) is a screening test developed and validated in Mexico to be administered in person by a professional. The objective is to evaluate the validity of administering the EDI test through telemedicine in terms of its diagnostic concordance with the face-to-face modality.

Methods:

This analytical, prospective, and cross-sectional study included patients aged 18-72 months and was conducted at a tertiary care hospital in Mexico City. The test was administered through telemedicine and subsequently in person. In addition, sensitivity and specificity data were reported with confidence interval of 95% (95% CI). The face-to-face evaluator was blinded to the telemedicine results.

Results:

Fifty children with a median age of 47 months participated in the study. A sensitivity of 100% (95% CI, 91-100) and specificity of 100% (95% CI, 70-100) overall were obtained. Language was the higher area with a sensitivity of 100 (95% CI: 91-100) and specificity of 90 (59-98); the results for the other areas are shown. The lowest sensitivity was neurological examination (67; CI 95%: 30-90) but has the highest specificity (98; CI 95%: 88-99).

Conclusion:

The EDI test implemented through telemedicine shows high correlation with the face-to-face modality, maintaining high sensitivity and specificity. These results make it an appropriate method for screening children of this age, although further larger studies are needed to corroborate it.
