U.S. Hospital EHR and Interoperability Statistics
A current, source-linked reference for writers, healthcare leaders, and teams tracking the scale of digital health infrastructure in U.S. hospitals.
Last updated July 17, 2026. Each figure below identifies the year of the underlying data.
What these statistics cover
Electronic record adoption is now nearly universal in U.S. hospitals. The more useful question is what those systems can do across organizational boundaries: exchange information, support patient access, connect with outside technology, and carry new clinical and operational capabilities.
This page brings together recent federal measures for those areas. The figures are not measures of go-live success or clinical performance; they describe adoption and reported capability across non-federal acute care hospitals unless a statistic says otherwise.
Key Figures
10 U.S. hospital EHR and interoperability statistics
>99%
Statistic 01
of non-federal acute care hospitals had adopted a certified EHR
The federal quick statistic reports adoption at more than 99% in 2024.

91%
Statistic 02
of office-based physicians had adopted a certified EHR
The same federal series puts office-based physician adoption at 91% in 2024.

70%
Statistic 03
of hospitals engaged in all four interoperability domains
In 2023, hospitals reported sending, receiving, finding, and integrating electronic health information from outside organizations.
Source: ASTP/ONC, Interoperable Exchange of Patient Health Information Among U.S. Hospitals (2023 data)
43%
Statistic 04
of hospitals routinely completed all four interoperability activities
Routine exchange was defined as often finding, sending, and receiving outside information while routinely integrating it into the EHR.

80%
Statistic 05
of hospitals used APIs for patient access through apps in inpatient settings
The rate followed growth from 68% in 2021 to 83% in 2023, before a modest decline in 2024.

69%
Statistic 06
of hospitals offered FHIR-based patient access apps in inpatient settings
Federal data show this capability increased from 56% in 2021 to 69% in 2024.
Source: ASTP/ONC, Growth of Health IT-Enabled Patient Engagement Capabilities Among U.S. Hospitals (2024 data)
90%
Statistic 07
of hospitals integrated third-party data into the EHR for at least one clinical purpose
This measure covers data flowing from third-party technology into the hospital EHR.
Source: ASTP/ONC, Hospital Use of APIs to Enable Data Sharing Between EHRs and Third-Party Technology (2024 data)
83%
Statistic 08
of hospitals provided EHR data to third-party technology for at least one clinical purpose
The federal brief distinguishes this outward data flow from integrating outside data into the EHR.
Source: ASTP/ONC, Hospital Use of APIs to Enable Data Sharing Between EHRs and Third-Party Technology (2024 data)
71%
Statistic 09
of hospitals reported using predictive AI integrated with the EHR
This was up from 66% in 2023; the federal analysis defines predictive AI as using statistical analysis and machine learning to classify or produce a risk score for individuals.
Source: ASTP/ONC, Hospital Trends in the Use, Evaluation, and Governance of Predictive AI (2024 data)
86%
Statistic 10
of hospitals submitted immunization data directly through the EHR
Among core public-health data types, direct electronic reporting ranged from 71% for electronic case reporting to 86% for immunization registry reporting.
