Introduction:

Computer applications in medical practice have allowed the development of novel forms of communication in the Health Care System. Standardization represents a necessary element for the sustainability and scalability of the developed software. In health systems there are various applications of the HL7 standard.

Objective:

To perform a Systematic Review of Literature (RSL) on the HL7 interoperability standard.

Methods:

The methodological proposal established by Petersen, which proposes five sequential steps such as: definition of research questions, definition of search criteria, definition of the selection criteria of primary studies, determination of the classification scheme, and data extraction and mapping study, was used for the definition and implementation of this study.

Results:

A total of 428,569 possible entries were obtained as a preliminary result. Applying the first inclusion and exclusion filter on the title, abstract and keywords, 864 documents remained, of which only 276 complied with having been published in the period under analysis (2017-2022). Only 72 of them allowed full access to the documentation and when analyzed, 51 were excluded for not offering information according to the research topic. A total of 21 articles were selected for further analysis.

Conclusions:

Based on the systematic review, it was possible to verify that in the optimization of communication processes, standards must be used to harmonize the exchange of information and provide a common language for all the agents involved.
