LRI Validation Suite LRI Validation Suite Meeting Rob Snelick—NIST April 24th, 2012

Agenda Tool status and plans LRI DSTU Version—demonstration of use – LIS validation is focus today LRI DSTU Errata Schedule -- Tuesdays, 1:00 PM EST – Next meeting: May 22nd (focus is EHR validation) – Additional meetings to be added if necessary – HL7V2_LRI_Testing Google Group will be used for notification

Tool Status and Plans Validation Tool for LRI (Release 1 for trial use) LRI IG DSTU Version – lri-dstu– – Notes: – Addresses LRI IG DSTU version submitted for ballot April 9 th, 2012 (Plus Errata) – All technical requirements for LIS validation incorporated – More testing needed and some odds and ends need addressed – Next target is May 22 nd —EHR functionality and Test Plan updated – Start to move into the phase of adding test cases However, the framework is in place – Changes to the tool will still be made; notice of such changes to be announced on the LRI Testing Google Group

Resources Tool Documentation Tab – Test plans, messages, profiles, and other testing artifacts Wiki Page—Validation Suite Resources – Latest version of test plans, messages, meeting minutes, etc Google Group – Discussion forum for LRI IG, Pilots, Validation Tool, Tool and Resources Updates, Release Notes, etc –

Plans Update EHR Validation – Test Plan, Juror Documents, Work flow, Communication Testing the validation tool – We need community feedback! – Get a head start on MU-2 certification More Test Cases (Test Coverage Matrix) – Lab Test Scope (to cover vocabulary recommendations) – Scenario test cases (e.g., P  F  C) – Technical requirements (e.g., Snapshot processing) – “Negative” testing User’s Guide and other documentation Exploring/Considering LOI and Compendium Validation – Depending on NIST resources/time

Tool Demonstration Big Picture – Validation Options – Profile Viewer – Vocabulary Browser – Documentation LIS Context-free Message Validation – Supported Profiles LIS Context-based Validation – Test Plan/Test Cases Overview – Data Sheet – Expected Validation Results

LIS (or Proxy) LIS Test Tool  Load  Cut/paste  Send HL7 V2 Lab Results Message Validation Report Context Free Testing: 1.Context free testing will validate a LRI message created by the LIS 2.The context (e.g., the type and results of the lab test) is unknown to the validation tool 3.Therefore not all conformance requirements of the LRI implementation guide can be assessed 4.However, the validation provides a simple and convenient method for testing message structure and most vocabulary Process: 1.An LRI message is created by the vendor’s LIS 2.The message is sent, pasted, or loaded in the test tool 3.A validation is performed LIS Context-Free Testing 1.Test any LRI message created by the LIS 2.Select “Message Validation” Tab 3.Select profile version (e.g., 4.Enter test messages into validation tool 5.Validation results appear

LIS LIS Test Tool select test case Test Data Sheet Manual entry of test data  Load  Cut/paste  Send HL7 V2 Lab Results Message Use Case Test Case Validation Report EHR transmits Hemoglobin blood test order to the LIS for John Doe along with pertinent demographic and order request data Lab Results Data Sheet John Doe DOB: 05/23/1959 Gender: M Result: 13.7 g/dL Range 13.2 – 16.2 Status: Final A lab test is ordered for a patient The specimen is collected, and is received and processed in the lab The lab result is produced and stored in the LIS database The lab result is transmitted to an ambulatory EHR The lab result is viewed in the ambulatory EHR 1.Local code 2.No code—text 3.LOINC code No LOINC given for results Test tool inspects OBX.3 for a specific LOINC code Inspect for only or inspect for one of 718-7, , , , , and ? For Discussion: 1.No suggested method given (Should we?) 2.With no method given we should expect one from a set of valid LOINC codes for this order (Lab dependent?) 3.If a specific method is given (is this typical/possible?) then should we look for a specific LOINC code in the sent message? For Discussion: 1.Does the LAB expect a local code for the order in a electronic order request? 2.Use Cases to consider: agreement/no agreement between LIS and EHR for local codes It is assumed Lab has capabilities for manual entry Data Entry DB Message

EHR Lab Message ACK Validation LRI EHR Test Harness Communication LRI Test Message Validation Report Test Data Test Case Use Case Juror Document ACK (LN) SNameValueREF Range FHemoglobin – 16.2 g/dL For Discussion: 1.What are the requirements on the EHR with regards to LOINC— given the LRI IG, CLIA, and meaningful use? 2.What are the EHR display (GUI) requirements for the received lab results? 3.What are the EHR storage requirements for the received lab results? 4.Given that the LOINC code is likely to be translated into the EHR internal representation, what lab test names need to be displayed in exact form and what lab test names can be displayed in an equivalence text (same concept)? 5.What qualifies as “equivalence—same concept”? How is that determined? Can it be? Expert inspector only? Should displaying of the LOINC text (only) be the requirement—i.e., no mapping? 6.What is the impact of sending only the LOINC code (i.e., no local code) on testing? Translated into internal representation Displayed as internal display text representation
