Integrating the Healthcare Enterprise Electronic Health Record Cardiology Laboratory Radiology Oncology Future Domains IHE IT Infrastructure Patient Care Coordination Patient Care Devices Pathology Eye Care Over 100 vendors and 20 professional societies involved worldwide 6 Technical Frameworks and 70+ integration profiles Testing at Connectathons and Demonstrations at Major Conferences Worldwide

Patient Care Coordination Support profiles addressing integration issues that cross providers, patient problems or time. Deals with general clinical care aspects rather than technology infrastructure. Addresses workflows and information sharing needs that are common to multiple specialty areas. Professional Input from ACP, ACEP, ACOG, HIMSS

Medical Summaries Value Proposition Supports key use cases for transfer of care: –Inpatient to PCP –PCP to Specialist Supports Transfer of Encoded –Problems –Medications –Allergies

Emergency Department Referral Value Proposition Nearly 5000 EDs in US Significant percentage of ED visits are referrals Shortage of critical health data for emergency department patients Need to improve communication of intended patient care plans to ED providers and ensure that no pertinent data is lost Streamline workflow by obviating telephone calls between busy clinicians

Exchange of Personal Health Records Value Proposition Provides a standards-based specification for managing the interchange of documents between a Personal Health Record and an EHR System to enable better interoperability between these systems.

Antepartum Summary Profile Value Proposition Over 4 million live births per year in US Obstetric patients must have a complete summary of antepartum care available for all care providers and at admission for labor and delivery. Incomplete information can be a danger to the mother and child and result in injury, inadequate treatment or undesirable outcome.

Functional Status Assessment Value Proposition The Institute of Medicine has determined that a high risk for errors occurs during the transfer of care. The Functional Status Assessment Profile (FSA) supports the handoff of assessment information between practitioners during transfers of care, cross- enterprise or intra-enterprise. Transfer of physician documentation provides medical assessment, diagnosis and treatment information. Transfer of nursing documentation provides assessment and treatment of human response (psychosocial, physiologic, emotional and spiritual) of patient/family to changing conditions.

Emergency Department Encounter Summary Value Proposition The Centers for Disease Control and Prevention (CDC) estimates that there were over 110 million emergency department visits in 2004 in the US ED visits account for as much as 40% of hospital admissions The ED Chart is the most common medical summary in use today This profile supports sharing of the clinical information in the ED chart with inpatient care providers and the patient's primary care physician.

Query for Existing Data Value Proposition Typical institutions have a large number of interfaces (30 – 60 or more) to manage, at a cost of $10,000 to $20,000 per year per interface. Few HL7 Version 2.X interfaces provide any query capabilities. Supporting a single standard to query clinical information is expected to reduce the overall costs of hooking together discrete clinical information systems.
