Area of Science:

  • Health Informatics
  • Public Health Surveillance
  • Digital Health

Background:

  • COVID-19 pandemic necessitates robust testing, traceability, and isolation strategies.
  • Challenges in SARS-CoV-2 test result reporting include errors, lack of interoperability, and privacy concerns.
  • Current methods like email spreadsheets are inefficient and prone to data integrity issues.

Purpose of the Study:

  • To design and develop an interoperable platform for reporting Polymerase Chain Reaction (PCR) SARS-CoV-2 tests.
  • To facilitate seamless data exchange between laboratories and the Chilean government.
  • To improve the accuracy and timeliness of COVID-19 case reporting.

Main Methods:

  • A six-stage methodology was employed for platform development.
  • Key stages included defining a minimum data set, process modeling, standards design, software development, testing, and implementation.
  • Fast Healthcare Interoperability Resources (FHIR) standards were utilized for interoperability.

Main Results:

  • Successfully implemented an interoperable FHIR platform for reporting PCR SARS-CoV-2 tests.
  • The platform demonstrated efficient performance with a response time of 240ms for 1000 requests.
  • Security measures included a private network, JSON Web Tokens for authentication, and access control lists.

Conclusions:

  • The developed platform is secure, tested, and currently in use by UC Christus Laboratory.
  • It effectively simplifies PCR SARS-CoV-2 test reporting, reducing errors and delays.
  • The FHIR-based solution is interoperable, successful, and available to the wider community.
