BACKGROUND
The information technology has transferred the paper-based healthcare sector into the digital form, where the patient information transfers electronically from one place to another. However, there are still a number of challenges and issues present in this domain because of the lack of proper standards, growth of new technologies (mobile, tablets, ubiquitous computing, etc.), and healthcare providers, who are reluctant to share patient information. Accordingly, a solid systematic literature review was conducted to understand the use of this new technology in the healthcare sector. The main purpose was to explore the relevant literature on Fast Health Interoperability Resources (FHIR) in the healthcare domain and identifies its implementation, exciting challenges, and open questions raised by us in healthcare regarding FHIR. To the best of the our knowledge, there was a lack of comprehensive systemic literature review that could focus on FHIR-based Electronic Health Record (EHR). In addition, FHIR was found to be the latest standard, but it was in the infancy stage of its development. Therefore, it was anticipated that the study under review was a hot area for us and that there were huge research opportunities in it.
OBJECTIVE
This paper aims mainly to explore the works in FHIR and performs a systematic review of the literatures surrounding FHIR, challenges to FHIR, implementation of FHIR, opportunities, and future FHIR applications.
METHODS
In January 2020, we searched articles published during January 2012 to December 2019 via all major digital databases in the field of computer science and healthcare, including ACM, IEEE Xplore, Springer, Google Scholar, PubMed, and ScienceDirect. Consequently, an analysis was carried out of the systematic literature review.
RESULTS
As a result, we reviewed more than 8000 scientific studies published in the last eight years, selected the most significant approaches, and thoroughly surveyed the health care field related to FHIR. We identified open questions, challenges, implementations models, used resources, beneficiary applications, data migration approaches, and goals of the FHIR.
CONCLUSIONS
Ultimately, the literature analysis necessitated the need and role of FHIR in the healthcare domain in the near future.
