Establishes EHR related priorities for HL7 Standardization Architectural issues – working with other technical committees Functional specification © HL7 2003

10 Original timeline Take 18 months to 2 years to write the standard
And then….. A customer arrived…… © HL7 2003

SCULLY URGES HOSPITALS TO HELP DEVELOP STANDARDIZED HEALTH RECORDS “Tom Scully, Administrator of the federal Centers for Medicare and Medicaid Services, today urged hospital executives to work with the government to develop standardized electronic health records.” © HL7 2003

12 Functional Model © HL7 2003

13 Project Target Initial Target EHR Functional Model and Standard-
Draft Standard for Trial Use Subsequently Full HL7 Standard Normative Document © HL7 2003

14 Task Create a Functional Model
Determine care delivery functions that are required across all implementations Determine infrastructure functions supporting care delivery Determine care delivery functions that are required in particular settings Allow for dynamic additions for innovation and elective functions Ballot this model as a standardised description of EHR functionality © HL7 2003

15 EHR Functional Model Care Delivery Functions Infrastructure functions
Profiles Functional Profiles Care Delivery Functions Vary across profiles Infrastructure functions © HL7 2003

16 EHR Functions © HL7 2003

25 EHR Function Specification Triplet
For each functional element specified: 1) WHAT - Statement of function(ality) 2) WHY - Rationale (for inclusion) 3) Conformance Criteria How = Implementation - OUT OF SCOPE © HL7 2003

26 Functional profiles © HL7 2003

27 What are functional profiles?
Sets of functions Care setting specific Based on consensus Purpose specific Registered for specific use Not controlled through standards process Standard Registered © HL7 2003

28 Care setting profiles Institute of Medicine
Agree standard care settings Minimal functionality required Express in EHR Functional Model Review functions Ballot functions © HL7 2003

29 Example functions Profiles Care delivery functions
Inpatient Outpatient Home Medication Administration Record Medication Administration Record Lifestyle Bed management Wellness Reminders Wellness Reminders Order Management Order Management Order Management Event Capture Event Capture Event Capture Event Capture Notes Notes Notes Notes Notes Notes Results Reporting Results Reporting Results Reporting Drug-Drug Interactions Drug-Drug Interactions Drug-Drug Interactions. Care delivery functions Demographic Management Demographic Management Security Security Security Security Security Security Security Security Standards Compliance Standards Compliance Infrastructure functions © HL7 2003

30 What are registered functional profiles?
Sets of functions Determined by users Determined by authoritative bodies Defined by quality or safety initiatives Defined by regulation Defined by payors © HL7 2003

31 Profiles Profiles Care Delivery Functions Infrastructure functions
Care Setting Profiles Use Profiles Care Delivery Functions Infrastructure functions © HL7 2003

32 Profiles Profiles Registered – Not in standard
Part of Standard Registered – Not in standard “How-to” is part of Standard Care Setting Profiles Provider Profiles Vendor Profiles Professional Association Profiles Regulation Profiles Accreditation Profiles © HL7 2003

33 Use of Profiles Profiles Outpatient HIPAA Care Setting Profiles
