DatasetsUS Hospital Participation in Health Information Networks
Construction of the file
This dataset uses information from the last three waves of the American Hospital Association (AHA) Information Technology (IT) Supplement Survey (2022-2024) to report on hospital’s participation in health information networks. The population of hospitals included in this dataset was limited to U.S. based non-federal acute care hospitals including general/medical hospitals, children’s hospitals, surgical, and cancer hospitals. In order to provide the most up-to-date information on hospital participation in health information networks, this dataset only includes the latest year of available data for a given hospital. For example, if a hospital responded to the survey in 2022 and 2024, only 2024 data are shown. This file includes 2,253 hospital responses from 2024, 639 from 2023, and 358 from 2022. All measures indicate participation as of the survey year.
Participation in a state, regional, and/or local health information exchange organization comes from the survey question, “Please indicate your level of participation in a state, regional, and/or local health information exchange (HIE) or health information organization (HIO).” A hospital was considered to be participating in an HIE/HIO if they reported that an HIE/HIO was operational in their area and they were participating and actively exchanging data in at least one HIE/HIO. Missing data were assumed to be non-participants.
Participation in a national network or EHR vendor network comes from the survey question, “Which of the following national health information exchange networks does your hospital currently actively participate in (i.e., operational exchange)?” A hospital was considered to be participating in a national network if they reported participation in at least one of the following national health information exchange networks: CommonWell Health Alliance, e-Health Exchange, or Carequality (network-to-network trust/governance framework). A hospital was considered to be participating in an EHR vendor network if they reported participation in an EHR vendor-based-network that enables record location and exchange within the EHR vendor’s network of users (e.g., Epic’s Care Everywhere). Missing data were assumed to be non-participants.
Participation in TEFCA comes from the survey questions, “Are you aware of the Trusted Exchange Framework and Common Agreement (TEFCA)?” “If yes, are you planning to participate in TEFCA exchange (such as through your HIE or other national network)?” A hospital was considered to be participating in TEFCA if they reported they were currently participating. A hospital was considered to be planning to participate in TEFCA if they reported they were planning to participate, regardless of whether they already had a partner/contract in place. Missing data were assumed to be non-participants.
Data linkages
This dataset contains linkage variables that can be used to combine this data with other hospital datasets.
The “aha_id” variable contains the unique identifier assigned by AHA to all hospitals. It can be used to link this dataset to AHA’s Annual Survey, the full IT Supplement, and other AHA databases and datasets.
The “mcrnum” variable is the hospital’s unique CMS Certification Number (CCN) identifier. The CCN is issued to all unique hospitals who are registered and participate in CMS programs and treat CMS beneficiaries. The variable can be used to link to a variety of CMS public use files relating to hospital participation, performance, and utilization. It is the identifier ASTP/ONC uses to identify hospitals in its public use files, like the Certified Health Information Technology Reported by Hospitals for Promoting Interoperability Performance dataset.
