Patient Portal Market 2025: Interoperability, AI & App Adoption Drive 18.7% CAGR

Patient Portal Market 2025: Interoperability, AI & App Adoption Drive 18.7% CAGR

Patient portals are moving beyond lab-results and appointment reminders. Backed by interoperability rules and massive app adoption, they’re becoming the front door for care coordination, payments, pharmacy, remote monitoring—and soon, AI-assisted self-service. The global market is projected to grow from USD 4.31B (2025) to USD 14.37B (2032) at 18.7% CAGR.

Why this matters now

  • Usage is surging: In 2024, 65% of individuals accessed health info online at least once (up from 57% in 2022). App-based access keeps climbing.
  • Apps > web: App access rose from 38% (2020) to 57% (2024), while web-only dropped from 60% to 42%. Fragmentation persists: 59% of people have multiple portals.
  • Policy tailwinds:
    • US: CMS Interoperability & Patient Access Rule entrenches FHIR-based APIs; TEFCA’s designated QHINs are standing up nation-scale exchange.
    • EU: European Health Data Space (EHDS) reached a provisional political agreement to enable cross-border access and reuse.
    • India: ABDM scale is huge—739.8M+ ABHA IDs and 490.6M+ linked records as of Feb 6, 2025.
  • UK proof point: NHS App logged 11.3M unique users in April 2025 and 51.2M logins that month—repeat prescriptions, test results, and messaging go mainstream.

Market snapshot (from our KBV Research report)

  • Size & growth: USD 4.31B (2025) → 14.37B (2032), 18.7% CAGR. North America leads today; Integrated portals outpace Standalone.
  • Leaders & movers: Epic, Oracle (Cerner), athenahealth, NextGen, eClinicalWorks, Veradigm, GE HealthCare, McKesson, Greenway, CureMD. Recent moves highlight AI assistants, ambient scribing, and multi-provider aggregation.

What’s changing inside the portal

Interoperability by default

FHIR APIs and payer/provider access rules shift portals from closed inboxes to data liquidity endpoints. Expect cleaner import of outside records, labs, imaging, and claims.

Network-level aggregation

TEFCA’s QHINs are making cross-network exchange routine—an antidote to the “five portals per patient” problem. Vendors are consolidating multiple patient accounts into one view.

Feature expansion

Beyond results and messages: bill-pay, price estimates, telehealth, e-prescriptions, and remote monitoring. NHS App’s prescription flows show how mainstream these are becoming.

AI in the workflow

Ambient scribing, smart replies, triage, and proactive nudges reduce admin burden while keeping clinicians in the loop. (Recent vendor announcements reflect this direction.)

Buyer checklist for 2025 RFPs

Interoperability: Certified FHIR R4 APIs, bulk data, SMART-on-FHIR app support; roadmap for TEFCA/QHIN connectivity.

Multi-provider experience: Single sign-on aggregation; record-linking across systems to cut duplicate logins. (A key pain point with 59% of users having multiple portals.)

Messaging governance: Tools for triage, autosuggestions, and configurable SLAs to curb message overload.

Medication & labs: End-to-end prescription workflows and near-real-time lab/result notifications (with clear release rules). NHS usage data validates demand.

Security & privacy: Role-based controls, audit trails, and consent consistent with HIPAA/Cures, GDPR/EHDS, and ABDM.

Equity & accessibility: Multilingual UI, low-bandwidth modes, proxy access, and accessibility compliance—critical to close the digital divide flagged by policymakers.

Regional dynamics (at a glance)

North America: Policy-driven demand (CMS APIs) + TEFCA connectivity. Health-system consolidation favors integrated portals tied to EHR cores.

Europe: EHDS will catalyze cross-border access and secondary-use ecosystems; vendors must align with GDPR-grade consent and data minimization.

Asia Pacific: Government digital-health programs (e.g., ABDM) and mobile-first adoption underpin growth; expect rapid supplier onboarding and pharmacy/workflow digitization.

Risks to watch

  • Fragmented patient experience (multiple portals and passwords) → prioritize aggregation and account-linking.
  • Message overload & clinician burnout without routing/automation.
  • Privacy & governance gaps as AI features roll out—ensure explainability, auditability, and consent logs aligned to local regs.

The 2025-2027 opportunity map

  • Chronic care programs: RPM + portal-based coaching and adherence pathways.
  • Pharmacy & payments: One-tap refills, prescription tracking, and price-transparency tools inside the portal. (NHS adoption signals user appetite.)
  • Data portability: TEFCA-enabled “bring-your-data” experiences and payer ↔ provider continuity.
  • Global rollouts: EHDS compliance in the EU; ABDM integrations in India using consented data sharing.
