Studies on the validation of minimum data sets from international information standards have drawn the attention of the academic community to the identification of necessary requirements for the development of Electronic Health Records (EHRs). The primary motivation of such studies is the development of systems using archetypes. The aim of this study was to validate the minimum data set that should be used when constructing an archetyped EHR for prenatal care applications in telehealth. In order to achieve this, a data validation tool was built and used by nine expert obstetricians. The statistical analysis employed was the percentage of agreement and the content validity index. The study was conducted in three steps: 1) Literature review, 2)Instrument development, and 3) Validation of the minimum data set. Of the 179 evaluated pieces of data, 157 of them were validated to be included in the archetyped record of the first prenatal consultation, while 56 of them were allocated for the subsequent consultation record. The benefit of this research is the standardization (data validation for an archetyped system) of prenatal care, with the perspective of employing, both nationally and internationally, an archtyped telehealth system.
