Slide 7
Current MeDHIX Model
The diagram shows an illustration of MeDHIX surrounded by three hospitals, one clinic and a cylinder with five ovals extending from it representing CHLCare and clinics. Arrows point from the main clinic and three hospitals towards the MeDHIX. A black circle encompasses MeDHIX and two of the hospitals. This circle constitutes the "Proxy Server." With a line linking MeDHIX to CHLCare, a yellow circle encompasses CHLCare with the five clinics. This circle constitutes the "Sub Network Organization."
Slide 8
MeDHIX is an Information Bridge
The diagram shows:
- Safety Net Clinics:
- Clinics in Montgomery County, MD; DC; and Virginia Counties.
- Use CHLCare.
- Health Information Exchange (HIE):
- Laboratory provider.
- Hospital Emergency Departments:
- Hospitals A, B, and C.
- All link to MeDHIX Exchange:
- Enterprise Service Bus.
- Routing and Transformation.
- Data Storage-edge servers.
- A Health Information Exchange to link Safety Net clinics to mainstream healthcare.
- Using CHLCare to make a single connection to MeDHIX, simplifying data exchange.
- Linking to Quest Diagnostics for Lab Results.
Slide 9

Slide 10
MeDHIX Initial Plan: Year 1
- "Quick Connect:"
- Partner with a large regional medical center.
- Use their proprietary data aggregation and display tools.
- Accelerate safety net learning and participation.
- Gain early understanding of benefits and challenges.
- CHLCare connection to bring "critical mass" of data quickly.
- View data using light weight, low cost browser based technology in the safety net clinics.
- Review and reconcile differing privacy regulations in 3 jurisdictions (Maryland, DC, Virginia).
- Develop easily understood data sharing and governance agreements for participating organizations and patients.
Slide 11
MeDHIX Initial Plan: Year 1
- Await outcome of the Office of the National Coordinator (ONC) Nationwide Health Information Network (NHIN) Demonstration Projects to:
- Learn from national efforts.
- Use ONC/NHIN standards based technical architecture.
- Minimize risk of misdirected expenditures.
- Explore open source solutions for safety net HIE.
- Build relationships with regional safety net providers, hospitals, and community organizations.
- Expand and improve the content of safety net EHRs.
- Implement at least 1 hospital <-> safety net clinic HIE.
Slide 12
MeDHIX Initial Plan: Year 2
- Move from proprietary to standards based infrastructure:
- Partner to implement open source solutions for safety net HIE.
- Expand HIE to two hospital emergency rooms (ERs) and safety net clinic shared EHR.
- Assess relative value of data elements to providers.
- Explore perceptions, barriers, benefits of HIE to various organizations and providers.
Slide 13
MeDHIX Initial Plan: Year 3
- Expand HIE to multiple hospital ERs.
- Expand HIE to include multiple EHRs.
- Consider HIE with pro bone specialty providers.
- Assess relative value of data elements to providers.
- Explore perceptions, barriers, benefits of HIE to various organizations and providers.
Slide 14
MeDHIX Actual Experience: Year 1
- Successfully viewed hospital ER data from a safety net clinic using Quick Connect approach.
- Jointly, with DC Primary Care Association, began a project to choose an EHR for selected DC safety net clinics.
- Generated substantial interest in the benefits of HIE for safety net populations.
- Focus on a region wide HIE approach.
- Good progress on regional privacy understanding.
Slide 15
MeDHIX Year 2: Proof of Principle Meets Reality
- Quick Connect partner insisted on thick client.
- MPI probabilistic match algorithm inadequate for safety net patients.
- Quick Connect partner sold product to commercial vendor, with complete change in product direction and goals.
- NHIN prototypes informative but not definitive national model or comprehensive standards.
- One set of safety net clinics not ready for HIE; focus was on EHR selection and adoption, a multi-year project.
Slide 16
MeDHIX Year 2: Proof of Principle Meets Reality
- Community hospitals added new prerequisites for safety net providers for patient identification and Health Insurance Portability and Accountability Act (HIPAA) protection.
- New project to issue photo IDs to safety net patients.
- Meets hospital need for positive patient identification.
- Facilitate and authenticate exchange of protected health information.
- Recurrent legal issues, costs, and lack of consensus concerning patient privacy and access to PHI.
- New organizations raise previously resolved issues.
- New members of existing organizations revisit old issues.
- Delays implementation.
- Fear, unwillingness, or excuse not to participate.
- Unnecessarily high legal expenses.
Slide 17
MeDHIX Year 2: Proof of Principle Meets Reality
- Interest of participants in HIE waxes and wanes.
- Other institutional priorities, IT and non-IT related.
- Near term needs trump longer term, more hypothetical projects.
- Stark exemption unintended consequences.
- Shifted hospital focus away from regional HIE.
- Opportunity to tie physicians to a hospital through EHR subsidy.
- Limited resources and competitive pressures undercut HIE.
- Hospital trust relationships.
- Larger competitor institutions not trusted as HIE operator.
- Unrelated litigation affected HIE collaboration among hospitals.
Slide 18
MeDHIX Year 2: Proof of Principle Meets Reality
- Population-stratified perceived benefits of HIE.
- Widely held view that HIE for safety net patients will lead to better quality care and cost reductions. Shared view of hospitals and safety net clinics. (cost/benefit analysis perceived as positive).
- No clear consensus that similar HIE benefits will accrue to insured patients who have strong ties to their personal physicians, smaller numbers of providers, better provider communication of health information, and established HIE methods.
- Risk to privacy perceived as outweighing benefits for cost and quality for insured patients. (risk/benefit analysis not always positive; disclosure may place patients or the hospital at risk).
- Closely held clinical information still seen as a competitive advantage by some providers.
Slide 19
MeDHIX Year 2: Proof of Principle Meets Reality
- HIE data sharing boundaries:
- Comfortable sharing data already being shared.
- Reluctant to share data not already being shared.
- Preference for role as silent partner in day to day HIE.
- Do not want responsibility for managing database inquiries.
- Will not permit direct access to their databases.
- Vendor contractual constraints.
- Firewall management and security concerns and costs.
- Unwilling to incur added support costs for HIE without clear benefits.
- Willing to incur at most small implementation costs.
- Probabilistic matching of patients not accepted.
- "Don't show me data that might not be for this patient."
- "I don't have time to sort out "possible matches."
Slide 20
MeDHIX Year 2: Proof of Principle Meets Reality
- Clinical data sharing observations.
- Safety nets and ERs may differ from other providers.
- "Complete" record not necessarily the best.
- "eChart synopsis most useful.
- Name of clinic providing care.
- Patient demographics.
- Encounter history, problem list.
- Allergies, meds, recent labs, if available.
- 1-2 pages maximum; too much information a deterrent to use.
- Discharge summaries of high value to safety net clinics.
- Images less useful initially, especially in safety net clinics.
- Printable eChart most useful in some ER settings.
- Ease of integration with ER workflow.
- Legal concerns of non-repudiation: "what did you know and when did you know it?"
Slide 21
MeDHIX Year 2: Proof of Principle Meets Reality
- Comprehensive, complex solutions.
- May be favored by large institutions.
- Unnecessary and inhibiting in smaller settings.
- Costly in $, time, and support.
- High end graphics work station (thick client).
- Multiple security patches; too much support expertise.
- Too much space required.
- Most data not needed; too much time to learn.
- Different providers value clinical data differently.
- Ease of use vs. complex privacy constraints.
- Multiple jurisdictions with conflicting requirements.
- Need to document compliance and exceptions easily.
Slide 22
MeDHIX Year 3: Problem Resolution for ER Project

Slide 28
Primary Care Coalition: Design and Implementation
The slide shows a screen shot of a Lab page from a patient's eChart.
- Current Design—Still Evolving.
Slide 29
Understanding Legal Constraints
MeDHIX does not display sensitive data initially
- Integrates a process for accessing sensitive data.
- Opt in vs. opt out.
- Mental health, substance abuse, HIV data.
- Document successive levels of patient permission.
- To access sensitive data.
- Hospital policy override ("break the glass").
Slide 30
Understanding Legal Constraints
The slide shows a portion of a disclaimer with a red circle around, "Data provided may not represent the complete patient history. Confirm all information with the patient and solicit additional information."
- The electronic record is probably not a complete historic depiction of the medical record.
Slide 31
Understanding Legal Constraints Mental Health, Drug Abuse, HIV not displayed
The slide shows a screen shot of a patient's eChart with red text stating, "Sensitive Data associated with Mental Health, Drug Abuse, and HIV are not displayed," and a circle around, "Authorize Sensitive."
- Sensitive Data Management.
Slide 32
Understanding Legal Constraints Authorization and Consent Recording
The slide shows a screen shot of a patient's eChart with the "Statement of Authorization to View Sensitive Data" opened.
- Sensitive Data Management.
Slide 33
Understanding Legal Constraints Patient has chosen not to share data
The slide shows a screen shot of an eChart-Metro DC Health Information Exchange page where a patient's name has been selected, but circled in red, shows that the patient has opted out of sharing data electronically.
Slide 34
Stakeholder Concerns Related to Process
- Measuring safety, quality, efficiency benefits of HIE difficult.
- Enthusiasm for HIE; legal, operational, financial concerns.
- Direction, time course, and benefits of HIE hard to discern.
- Balancing pressing hospital IT needs with HIE collaboration.
- Return on investment (ROI) clear for hospital IT; ROI speculative for HIE.
- HIE planning and technology investment substantial.
Slide 35
Hospital Concerns, Limitations, and Constraints
- Constraints imposed by existing HIS contracts.
- Security.
- Prohibition of non-vendor code.
- Change in liability/responsibility contract clauses.
- "Invisible Partner" in HIE.
- Need to limit time, resources, cost of HIE participation.
- Adaptation should be HIE responsibility; little or no change for hospital.
- Legal liability for privacy/confidentiality breaches.
- Business risk for privacy/confidentiality breaches.
Slide 36
Stakeholder Observations on the Value of HIE
- When it is integrated into day-to-day business processes.
- Not an easy or inexpensive task.
- Requires considerable staff time and sophistication.
- When it becomes a standard mechanism for multi-provider communication and care coordination.
- When data affecting a treatment decision is made available that would not have been known using traditional methods.
- Value propositions for one organization do not always equate to value for another.
- The "grand vision" must be coupled to a practical ROI.
Slide 37
Some Final Thoughts about Elephants
- A critical mass of clinical data essential for successful HIE.
- A special challenge for safety net clinics (staff, $$).
- Limited safety net EHR data -> little or value to hospital or consultants.
- No return of discharge summaries or consultant notes -> no value to safety net clinics.
- Shifting from opt-in to opt-out if legally sound, but is uncomfortable for many organizations.
- The greatest benefits of HIE are likely to come from both individual and system wide practice re-design, not from HIE itself.
