Architectural patterns for health information systems: a systematic review.

ABSTRACT:

Background

Health information systems (HIS) are critical for digital health transformation, yet fragmentation and poor interoperability adoption remains a major challenge.

Objectives

This study systematically reviews architectural patterns used in HIS and evaluates their alignment with ecosystem-level requirements.

Methods

Following PRISMA 2020 guidelines, a systematic literature review was conducted across Scopus, IEEE Xplore, PubMed, and Web of Science (2020-2025). Eligible studies described, evaluated, or proposed HIS solutions.

Results

From an initial set of 304 records, 89 met the inclusion criteria. Service-based and decentralized/distributed ledger architectures were predominant, with emerging models integrating edge computing and modular design. FHIR-ba
