The effect of participation in accountable care organization on electronic health information exchange practices in U.S. hospitals

Abstract

Background: Accountable care organizations (ACOs) are a recent incentive program that are designed to address inefficiencies in the U.S. health care sector. To meet their design objectives, ACO participants must engage in greater electronic health information exchange (HIE) practices both internally and externally with care participants, such as patients and other providers.

Purpose: The aim of this study was to examine the relationship between hospital participation in ACOs and electronic HIE practices with different participants of care and how these practices vary differentially across market types.

Approach: Grounding our work in the reward-motivational view of organizational action, we proposed hypotheses that linked hospital participation in ACOs to three dimensions of HIE practices (intraorganizational, interorganizational, and provider-patient HIE practices). We tested our hypotheses by analyzing a sample of 1,926 hospitals.

Results: Hospital participation in ACOs is associated with greater intraorganizational and provider-patient HIE practices, but not interorganizational HIE practices. We also found that whereas the relationship between ACO participation and intra- and interorganizational HIE practices remains unchanged irrespective of the degree of competition in the health care market, the relationship between ACO participation and provider-patient HIE practices holds true only for hospitals operating in noncompetitive markets.

Practice implications: Our results showed that hospitals participating in ACOs vary in their HIE practices, and attributes of the local market in which ACO participants operate in contribute to this variation. These insights should provide guidance to researchers, policymakers, and hospital administrators who aim to improve the effectiveness of ACOs.
