Review of User Stories1. Requestor makes request to a provider for patient data on

eHealth Exchange2. Provider receives request from eHealth Exchange for patient

information, retrieves PCD from PCD repository and applies, returns status to PCD repository

3. PCD repository receives request for PCD from eHealth Exchange partner, returns PCD, accepts status from AC decision

4. PCD repository receives request for new account from healthcare consumer, possibly involving providers

5. PCD repository allows management of PCD from healthcare consumer

6. Healthcare consumer manages PCD from PCD repository account, views AC status reports

Functional Requirements

• Definition of a Functional Requirement– Address function (what) not implementation (how)– Does not reference other requirements – Contains all information required– Contains only one functional requirement

• Exercise: how are we changing IG use case 3 predicates in the proposed J-UT user stories?– Illustrates change from original– Allows mapping of existing UC 3 requirements

Basic Flow of Use Case (UC) 3• Use Case Development and Functional Requirements for

Interoperability (Implementation Guide)• Basic Flow

– Actor– Role– Event– Inputs– Outputs– Type

• Mapped to J-UT pilot for coverage test– Consider the Information Interchange type of requirements

04/30/2013 6

Functional Requirements of UC 3• Use Case Development and Functional Requirements for

Interoperability (Implementation Guide) – Very broadly worded

• Functional requirements– Initiating System– Action of Initiating System– Information Interchange Requirement Name– Receiving System– Action of Receiving System

• Mapped to J-UT pilot for coverage test– Consider the Information Interchange type of requirements

04/30/2013 7

System Requirements UC 3• Use Case Development and Functional Requirements for

Interoperability (Implementation Guide)• System requirements

– System– System Requirements

• Mapped to J-UT pilot for coverage test– New systems added

• Provider/ Healthcare Provider Organization Electronic System

• Consent Repository Account Holder's Electronic System

04/30/2013 8

Basic Flow of J-UT• Step 1: review “J-UT Basic Flow” for concurrence• Result of mapping to J-UT to UC3 Basic Flow

– Use exchange format from previous pilots – Review format for request to consent directive, including specifying

patient /account number and consent directive repository– Need to review format for returning consent directive, including

specifying patient HIO identifier– Use exchange format from previous pilots, #2– Need to create format for sending result of decision to consent

directive repository, including detail appropriate for patient

04/30/2013 9

Basic Flow of J-UT (Pre/Post)• Result of mapping to J-UT to UC3 Basic Flow• Optional Preconditions

– Review format for establishing authentication exchange?– Create format for exchange of Consent Repository Account Holder

and HIO identifiers?– Create format for exchange of Consent Repository Account Holder

and HIO identifiers?• Optional Post Conditions

– Create format for exchange of Consent Repository location and Account Holder identifier to 2nd requestors associated with data exchanged with 1st requester (provenance)?

04/30/2013 10

Functional Requirements of J-UT• Step 2: review “J-UT Functional Requirements” for concurrence• Result of mapping to J-UT to UC3 functional requirements

– Need to review format for request to consent directive, including specifying patient /account number and consent directive repository

– Need to review format for returning consent directive, including specifying patient HIO identifier

– Need to create format for sending result of decision to consent directive repository, including detail appropriate for patient

– Need to chose format for sending result of decision to consent repository account holder's electronic system?

04/30/2013 11

System Requirements of J-UT

04/30/2013 12

• Step 3: review “J-UT System Requirements” for concurrence• Result of mapping to J-UT to UC3 system requirements

– Do we need to create format for exchange of Consent Repository Account Holder and HIO identifiers?

– Need to create format for sending result of decision to consent directive repository, including detail appropriate for patient

– Need to choose format for sending result of decision to consent repository account holder's electronic system?

Detailed Functional Requirements Step 1: review “J-UT Basic Flow” for concurrence Step 2: review “J-UT Functional Requirements” for concurrence Step 3: review “J-UT System Requirements” for concurrence• Step 4: review J-UT detailed functional requirements• Assign priority to initial requirements

– Requirements from coverage check– Requirements from 04/23/2013 teleconference– Requirements from previous pilots– Additional sources of requirements (future work)

• E.g. HL7 Implementation Guide for CDA® Release 2: Privacy Consent Directives, Release 1

Questions?

• For example:• Can we add new functional requirements?• Can we suggest new sources of functional requirements?

(no standards yet)

Plan of Action

• Upon agreement of the participants the POA is • Identify the elements available from previous DS4P pilots• Scope level of effort, decide on extended scenario• Determine first draft of functional requirements• Review standards available for returning information on requests• Determine gaps or extensions required in standards• Create XDS.b repository holding PCD• Stand up information holders and requestors• Identify remaining pieces • Document and update IG with results of our experience

Scope of the Pilot• 1.      Define the exchange of HL7 CDA-compliant PCD between a

PCD repository and a provider evaluating that includes a report on the outcome of the request back to the healthcare consumer. 

• 2.      Additional goal: use of identifiers that can uniquely identify the healthcare consumer and PCD repository used to report the outcome of the request back to the healthcare consumer by healthcare consumer’s provider and subsequent EHR custodians.

• 3.      Stretch goal: use of the PCD repository as a proxy allowing direct authentication by the healthcare consumer to the provider, subsequently reducing correlation errors.

2104/30/2013

Secondary Goals of the Pilot• Exchange and enforce privacy metadata to ensure proper policy-

based disclosure and redisclosure of PHI• Accept and display reports from information owners on access

control decisions for requests for the patient’s PHI• Create a token passing scheme that facilitates secondary use

reporting • Demonstrate dynamic reporting of access to a patient’s PHI and

their ability to change their PCD using their PCD central repository

2204/30/2013

Available Roles• Holder of PHI that is participating on the eHealth Exchange

– Accepts eHealth Exchange compliant request– Retrieves PCD and reports result of request– Synthetic Patient Data is Available

• Requester of PHI that is participating on the eHealth Exchange– Makes eHealth Exchange compliant request

• Repository holding subject’s Patient Consent Directive (PCD)– Transmits PCD to trusted eHealth Exchange requesters– Accepts policy created by subject of shared PHI – Passes HL7-compliant PCD– Displays result of the request transmitted from holder of PHI
