assessing the impact of health system organizational structure on hospital electronic data sharing
Journal of the American Medical Informatics Association, 2018Co-Authors: Jay A Holmgren, Eric W FordAbstract:Objective Horizontal consolidation in the hospital industry has gained momentum in the United States despite concerns over rising costs and lower quality. Hospital systems frequently point to potential gains in Interoperability and electronic exchange of patient information as consolidation benefits. We sought to assess whether hospitals in different health system structures varied in their interoperable data sharing. Materials and methods We created a cross-sectional national hospital sample from the 2014 AHA Annual Survey and 2015 IT Supplement. We combined the existing taxonomy of health system organizational forms and the ONC's functionality-based, technology-agnostic definition of Interoperability. We used logistic regression models to assess the relationship between health systems' organizational forms and Interoperability engagement, controlling for hospital characteristics. Results We found that Interoperability engagement varied greatly across hospitals in different health system structures, with facilities in more centralized health systems more likely to be interoperable. Hospitals in one system type, featuring centralized insurance product development but diverse service offerings across member organizations, had significantly higher odds of being engaged in interoperable data sharing in our multivariate regression results. Discussion The heterogeneity in health system Interoperability engagement indicates that incentives to share data vary greatly across organizational strategies and structures. Our results suggest that horizontal consolidation in the hospital industry may not bring significant gains in Interoperability progress unless that consolidation takes a specific business alignment form. Conclusion Policymakers should be wary of claims that horizontal consolidation will lead to Interoperability gains. Future research should explore the specific mechanisms that lead to greater Interoperability in certain health system organizational structures.

assessing the impact of health system organizational structure on hospital electronic data sharing
Academy of Management Proceedings, 2018Co-Authors: Jay A Holmgren, Eric W FordAbstract:Horizontal consolidation in the hospital industry has continued to gain momentum in the United States despite concerns over rising costs and lower quality. Hospital systems often justify their merger and acquisition behavior by highlighting improved ability to control costs with Interoperability, the electronic sharing of patient information, across member institutions. Previous research has shown that while the overall level of Interoperability engagement is low, hospitals’ that are members of health care systems are more likely to share data electronically. We sought to determine whether health system structures are associated with hospital engagement in Interoperability. We used national hospital data and combined existing taxonomies of health system structure to the functionality-based, technology-agnostic definition of Interoperability promulgated by the Office of the National Coordinator for Health IT. We found that Interoperability engagement varied greatly across hospitals using different system s...

using the levels of conceptual Interoperability model and model based data engineering to develop a modular Interoperability framework
Winter Simulation Conference, 2011Co-Authors: Saikou Y Diallo, Andreas Tolk, Jaso Graff, Anthony ArracoAbstract:This paper describes how to use the Levels of Conceptual Interoperability (LCIM) as the theoretical backbone for developing and implementing an Interoperability framework that supports the exchange of XML-based languages used by M&S systems across the web. The principles of Model-based Data Engineering (MBDE) are integrated within the framework to support the interactions between systems across the layers of the LCIM. We present a use case that shows how the framework supports the Interoperability of heterogeneous military systems.

Maturity model for enterprise Interoperability
Enterprise Information Systems, 2013Co-Authors: Wided Guédria, Yannick Naudet, David ChenAbstract:Existing Interoperability maturity models are fragmented and only cover some Interoperability aspects. This paper tentatively proposes a maturity model for enterprise Interoperability which is elaborated on the basis of existing ones. It is also consistent to the Enterprise Interoperability Framework currently under the standardization process. After a brief introduction, the paper reviews existing maturity models for Interoperability and recalls the basic concepts of the Enterprise Interoperability Framework. Then the proposed maturity model for enterprise Interoperability is discussed in details. Metrics for determining maturity levels are presented as well. Finally the last part of the paper gives the conclusions and perspectives for future work.

multi agent hla enterprise Interoperability short lived ontology based
The International Workshop on Modelling & Applied Simulation part of, 2009Co-Authors: Gregory Zacharewicz, David Chen, Olivier Labarthe, Bruno VallespirAbstract:This paper aims at proposing an implementation of the Federation oriented Enterprise Interoperability concept, using Multi Agent / HLA paradigm and the rising notion of Short-Lived Ontology. We give first, a review of ongoing researches on Enterprise Interoperability. Then, we recall on Artificial Agent Concept and HLA Stan-dard that appear to be adequate to support execution of the studied concept. Indeed, on the one hand Agent dialogue fits the concept of information exchange in a federated enterprise Interoperability approach, on the other hand the HLA standard, initially designed for military M&S purpose, can be transposed for enterprise Interoperability at the implementation level, reusing the years of experiences in distributed systems. From these postulates, we propose the first Agent/HLA framework Short-Lived Ontology based to implement distributed enterprise models from the conceptual level of federated enterprise Interoperability approach.

european initiatives to develop Interoperability of enterprise applications basic concepts framework and roadmap
Annual Reviews in Control, 2003Co-Authors: David Chen, Guy DoumeingtsAbstract:Abstract This paper presents basic concepts, framework and roadmaps to develop Interoperability of enterprise applications and software. The paper is a summary of the main work carried out in Europe to elaborate Interoperability development roadmaps and to prepare forthcoming R&D projects under the Six Framework Programme (FP6). The originality of the approach is to tackle Interoperability problem from multiple but integrated views. The state-of-the-art, user requirements and visions relating to develop Interoperability are presented. Recommendations for future works are discussed and conclusions given at the end.

towards semantic Interoperability for electronic health records
Methods of Information in Medicine, 2007Co-Authors: Sebastian Garde, Petra Knaup, Evelyn J S Hovenga, Samuel HeardAbstract:Objectives: In the field of open electronic health records (EHRs), openEHR as an archetype-based approach is being increasingly recognised. It is the objective of this paper to shortly describe this approach, and to analyse how openEHR archetypes impact on health professionals and semantic Interoperability. Methods: Analysis of current approaches to EHR systems, terminology and standards developments. In addition to literature reviews, we organised face-to-face and additional telephone interviews and tele-conferences with members of relevant organisations and committees. Results: The openEHR archetypes approach enables syntactic Interoperability and semantic interpretability – both important prerequisites for semantic Interoperability. Archetypes enable the formal definition of clinical content by clinicians. To enable comprehensive semantic Interoperability, the development and maintenance of archetypes needs to be coordinated interna- tionally and across health professions. Domain knowledge governance comprises a set of processes that enable the creation, development, organisation, sharing, dissemination, use and continuous maintenance of archetypes. It needs to be supported by information technology. Conclusions: To enable EHRs, semantic Interoperability is essential. The openEHR archetypes approach enables syntactic Interoperability and semantic interpretability. However, without coordinated archetype development and maintenance, ‘rank growth’ of archetypes would jeopardize semantic Interoperability. We therefore believe that openEHR archetypes and domain knowledge governance together create the knowledge environment required to adopt EHRs.
