Deploying Patient-Facing Application Programming Interfaces: Thematic Analysis of Health System Experiences

Abstract

Background Health systems have recently started to activate patient-facing application programming interfaces (APIs) to facilitate patient access to health data and other interactions. Objective This study sought to ascertain health systems’ understanding, strategies, governance, and organizational infrastructure around patient-facing APIs, as well as their business drivers and barriers, to facilitate national learning, policy, and progress toward adoption. Methods We performed a content analysis of semistructured interviews with a convenience sample of 10 health systems known to be leading adopters of health technology, having either implemented or planning to implement patient-facing APIs. Results Of the 10 health systems, eight had operational patient-facing APIs, with organizational strategy driven most by federal policy, the emergence of Health Records on iPhone, and feelings of ethical obligation. The two priority use cases identified were enablement of a patient’s longitudinal health record and digital interactions with the health system. The themes most frequently cited as barriers to the increased use of patient-facing APIs were security concerns, an immature app ecosystem that does not currently offer superior functionality compared with widely adopted electronic health record (EHR)–tethered portals, a lack of business drivers, EHR vendor hesitation toward data sharing, and immature technology and standards. Conclusions Our findings reveal heterogeneity in health system understanding and approaches to the implementation and use of patient-facing APIs. Ongoing study, targeted policy interventions, and sharing of best practices appear necessary to achieve successful national implementation.

Rapid design and implementation of an integrated patient self-triage and self-scheduling tool for COVID-19

“…However, in the current state, use of the EHR-tethered portal is critical to realizing the full operational benefit of self-triage tools. 24 Additionally, there is an important distinction between many of the tools on the market that are meant to provide likelihood of having COVID-19 and those meant for triage. 25 By designing this as a triage tool, we were able to base the clinical logic on well-established triage principles and clinical guidelines for upper respiratory infections, like influenza.…”

Patient Portal Barriers and Group Differences: Cross-Sectional National Survey Study

“…However, an overall adoption rate of 25% is modest and means that many patients are still not using patient portals. To increase adoption, some health care systems have started offering access to patient portals through smartphone apps [ 22 ]. Smartphone app access allows patients to integrate data from multiple patient portals and may increase access for patients who do not have access to a home computer.…”

The role of artificial intelligence in the application of the integrated electronic health records and patient-generated health data

“…Technologies like the application programming interfaces (APIs) are portable packages of code that make it possible to add AI functionality to existing software packages and products. [69] They can add capabilities for image recognition to home security systems, calling out patterns and insights of interest in PGHD. APIs could also facilitate data accuracy, privacy, and security by their authentication function.…”
