2 1 PRESENT Review where we are today 2 LESSONS LEARNED Challenges & how we dealt with them 3 FUTURE Planned initiatives
Web user interface – human consumption Application programming interface – machine consumption
Based on IHE Sharing Value Sets (SVS) Profile XML-based In use by USHIK, Mayo & Mitre Returns value sets by: OID OID & version Measure ID
11 Challenge Curation Outcomes quality measures 84,228 84,228 unique codes 1,558 1,558 unique value sets CLEAN with in within 4 4 months
12 Challenge Curation Outcomes Used UMLS® Terminology Services and RxNORM APIs Used UMLS® Terminology Services and RxNORM APIs Triangulation between code system, code & description Checks for: -Incorrect/malformed codes -Code System/Code mismatch -Code/description mismatch
13 Challenge Curation Outcomes EXAMPLES (Code reformatted) SNOMEDCT > Diphtheria, tetanus and pertussis vaccine adverse reaction (disorder) ICD10CM M01x69 -> M01.X69Direct infection of unspecified knee in infectious and parasitic disease classified elsewhere LOINC ┬ á -> Systolic blood pressure
14 Challenge Curation Outcomes EXAMPLES (Code system changed) ICD10CM -> ICD10PCS 02H732G Insertion of Pressure Sensor into Left Atrium, Percutaneous Approach ICD10CM -> ICD9CM OPN AORTIC VALVULOPLASTY LNC -> CPT Renal function panel
15 Challenge Curation Outcomes EXAMPLE (code/code system mismatch) (urine screen for chlamydia) code for the term (wrong) (urine screen for chlamydia) code for the concept (OK)
16 Challenge Curation Outcomes EXAMPLE (code/description mismatch) 99411Chemotherapy administration; intravenous, push technique, each additional substance/drug (List separately in addition to code for primary procedure) 96411Chemotherapy administration; intravenous, push technique, each additional substance/drug (List separately in addition to code for primary procedure)
17 Challenge Curation Outcomes THIRTEEN grueling rounds of corrections over a 4-month period Corrected: codes value sets -All 94 measures
Process Initiatives (in collaboration with HHS partners) Governance process for value set editing, approval and publishing Value set review to validate against purpose of measure Tooling for VS maintenance and authoring Direct access to online code systems (should eliminate errors encountered) Access to UMLS synonymy, hierarchy and relationships Built-in quality checks to alert on potential errors Automated alerts when new code system releases require value set refresh Evaluate CTS2 suitability for use with VSAC Opportunities to improve value set consumption Integration with Measure Authoring Tool (MAT) (Partial list)
