I recently had the privilege of delivering the keynote at Duke University’s Third Annual Informatics Conference, “Business Transformation Through Informatics” in North Carolina, followed by a congressional staff briefing organized by Health IT Now in Washington D.C. I thought I would summarize the key takeaways here since the presentations and discussions which followed seemed to achieve a degree of resonance with the respective audiences.
I should preface this to say that each of these observations are my own, based on exhaustive research of different models worldwide. I regularly work with regional and national governments around the world to design their national healthcare architectures, establish a shared services strategy, and leverage cloud computing to cost-effectively share essential infrastructure and expertise across a region.
Care coordination realistically models health information exchange as a network of participants rather than as a point-to-point exchange
Health information exchange is better modeled as a complex network of participants rather than a simplified point-to-point exchange of information. Each exchange of health information requires numerous supporting utility services – to check authorization, lookup clinician and patient registries, normalize terminology, aggregate patient health information across disparate sources, etc. Healthcare itself more closely follows a document-centric model of workflows such as that modeled by HL7 CDA (Health Level 7 Clinical Document Architecture), embodied as standard healthcare documents such as encounter and discharge summaries, request for consult, etc. Care coordination requires timely and secure access to a shared patient record across a region, inclusive of the patient, the caretakers, the clinicians and the institutions all participating in the patient’s care.
Care coordination, quality metrics and clinical decision support require a standard informatics model
A key success factor in health reform is the establishment of a shared summary care record built upon a standard informatics model, leveraging HL7 CDA and terminology standards including SNOMED CT, LOINC, ICD10, and for medications, RxNorm or ATC. The Consolidated CDA represents a harmonized set of recommendations across HL7 balloted CDA implementation guides, IHE Implementation Guides, Health Story Project and S&I Framework. HL7 CDA has been proven worldwide, including the use of HL7 CDA for epSOS (Smart Open Systems for European Patients) transborder exchange of summary health records and medication histories. A standard informatics model enables doctors to pose queries like “Tell me which of my patients have a particular condition and are taking a particular medication” – perhaps there is a new potential drug interaction or a change in recommended treatment procotol. Clinical decision support, population health, quality metrics, comparative effectiveness research all depend on a standardized informatics model.
Care coordination, quality metrics and clinical decision support require a critical mass of shared patient health information across all participants in the region
Countries that require electronic submission of encounter and discharge summaries within 24-48 hours of care episodes, have significantly accelerated their progress towards health reform. This protected health information is then aggregated, normalized and made accessible as a shared patient health record through a regional HIE using web-based service APIs. Patients and clinicians alike are given immediate access that is both secure and transparent. Patients are able to directly consent and authorize access to health professionals, as well as audit specific disclosures, thereby establishing trust in the system. Independent audits are conducted to ensure “need to know” and “least privileged” access to protected health information. A critical mass of shared patient health information is established because all healthcare participants in a region are included. Goals for patient safety and improved care delivery at reduced costs are met because patient care can be coordinated across each of the specialists and institutions in a region.
Time to Value: health reform must be accelerated
The time to build out the necessary infrastructure must proceed aggressively, such that the collaborative economic model can be established before the stimulus funds are exhausted. The collaborative economic model depends on achieving a critical mass of normalized health information. Once a minimum set of normalized health information is established, local business innovation can develop value-add services, which further drive value in the network. Examples of value-add services include drug interaction checks, clinical trial patient recruitment, clinical decision support, and comparative effectiveness of particular treatment protocols, institutions, clinicians, even patient-focused wellness and behavior modifications. Time to Value is the single biggest cause of failed HIEs worldwide – they took too long to establish a sustainable business model, ran out of funds before completing the necessary infrastructure, and ignored the importance of a standard informatics model.
Regional HIEs form the backbone of a shared services strategy
A Shared Services model is a means to cost-effectively share the necessary infrastructure for health information exchange, while creating a collaborative economic model that drives local innovation and accelerates adoption of advanced healthcare usage models. Regional HIEs become the logical organizing point to collect, host and store the normalized health information, to centrally monitor and enforce patient consent and authorization, to offer value-add services which drive further value in the network. Regional HIEs provide necessary infrastructure which must be must be organized, monitored and enforced similar to transportation and utilities, to ensure interoperability at both national and regional levels. Health reform which follows a balanced approach across business drivers and metrics, policy and standards, architecture, and reimbursement and investment models demonstrate the highest levels of maturity and return on investment.
