Mapping LOINC with thai local code

  1. 1. Thai Health Informatics Academy T h a i H e a l t h I n f o r m a t i o n S t a n d a r d D e v e l o p m e n t C e n t e r ( TH I S ) MAPPING THAI LOCALLABORATORY CODES WITH LOINC : THE PRELIMINARY REPORT WANCHANA PONTONGMAK Dr. BOONCHAI KIJSANAYOTIN
  2. 2. Thai Health Information Standard Development Center(THIS)Thai Health Informatics Academy Outline  Background & Rational  LOINC  Objective  Materials & Method  Result  Conclusions & Discussions
  3. 3. Thai Health Information Standard Development Center(THIS)Thai Health Informatics Academy Background & Rational  Health data standard facilitated sharing and exchanging health data with semantic interoperability  Thailand does not have standards for clinical laboratory tests
  4. 4. Thai Health Information Standard Development Center(THIS)Thai Health Informatics Academy Background & Rational  Thai healthcare service will adopt LOINC as the national laboratory standard  Suitability of LOINC for Thai healthcare service indicated by mapping local tests with LOINC
  5. 5. Thai Health Information Standard Development Center(THIS)Thai Health Informatics Academy What is LOINC ?  Logical Observation Identifiers names and codes (LOINC) is a unique identifier for medical laboratory and clinical observations • LOINC contains 70,689 terms • LOINC is broadly used in many countries
  6. 6. Thai Health Information Standard Development Center(THIS)Thai Health Informatics Academy What does LOINC look like?  Serial code 1-5 digit and 1 check digit  The name consist of 6 axes <component>:<property>:<time>:<sample>:<scale>:<method> 20509-6 Hemoglobin : MCnc : Pt : Bld : Qn : Calculated  Long name Hemoglobin [Mass/​volume] in Blood by calculation
  7. 7. Thai Health Information Standard Development Center(THIS)Thai Health Informatics Academy Objective  This study aims to study the coverage of LOINC terms with Thai local laboratory terms
  8. 8. Thai Health Information Standard Development Center(THIS)Thai Health Informatics Academy Research Concept & Expected Results  Mapping LOINC with local laboratory tests to study the coverage of LOINC for Thai local laboratory tests in order to support decision making by policy maker
  9. 9. Thai Health Information Standard Development Center(THIS)Thai Health Informatics Academy Materials & Method  Local laboratory test form 1. Thai Comptroller General’s Department’s reimbursement codes list. 3 selected groups form 16 reimbursement groups (721 terms)  Laboratory tests (498 terms)  Radiology tests (182 terms)  Special tests (41 terms)
  10. 10. Thai Health Information Standard Development Center(THIS)Thai Health Informatics Academy Materials & Method 2. Burirum province’s Laboratory information system’s code list. (732 terms)  Laboratory tests (596 terms)  X-ray tests (136 terms)
  11. 11. Thai Health Informatics AcademyThai Health Information Standard Development Center(THIS) - Available at www.loinc.org • LOINC database and RELMA Materials & Method
  12. 12. Thai Health Informatics AcademyThai Health Information Standard Development Center(THIS) Materials & Method
  13. 13. Thai Health Information Standard Development Center(THIS)Thai Health Informatics Academy Materials & Method  Importing local terms to RELMA  Text tab delimited file  Verifying unreadable terms  Non-generic name  Inaccurate data entry  Local name
  14. 14. Thai Health Informatics AcademyThai Health Information Standard Development Center(THIS)  Mapping  RELMA  Algorithm Materials & Method
  15. 15. Thai Health Information Standard Development Center(THIS)Thai Health Informatics Academy Mapping type Local LOINC Local test LOINC name code codes 199 VCT 3183-1 Clotting time : Time : Pt : Bld : Qn : Lee White 20570-8 Hematocrit : VFr : Pt : Bld : Qn 4544-3 Hematocrit : VFr : Pt : Bld : Qn : Automated 48703-3 Hematocrit : VFr : Pt : Bld : Qn : Estimated 31100-1 Hematocrit : VFr : Pt : Bld : Qn : Impedance 264 Hct 4545-0 Hematocrit : VFr : Pt : Bld : Qn : Spun 32354-3 Hematocrit : VFr : Pt : BldA : Qn 42908-4 Hematocrit : VFr : Pt : BldC : Qn 41654-5 Hematocrit : VFr : Pt : BldV : Qn 310 จอง / เตรี ยมผ่าตัด
  16. 16. Thai Health Information Standard Development Center(THIS)Thai Health Informatics Academy Result  More than 80% could be mapped to LOINC, of which 23.58% are 1-1 and 63.07% are 1-Many Mapping type Thai’s CGD Burirum’s LIS N % N % 1-1 117 16.23 221 30.19 1-Many 467 64.77 395 53.96 Unmapped 137 19.00 116 15.85 total 721 100.00 732 100.00
  17. 17. Thai Health Information Standard Development Center(THIS)Thai Health Informatics Academy Conclusions & Discussions  One to many results  LOINC has higher level of granularity than local tests  6 axes of LOINC  Local code has 1-2 important axis
  18. 18. Thai Health Information Standard Development Center(THIS)Thai Health Informatics Academy Conclusions & Discussions  Unmapped results  Non-generic and Local names  Not part of laboratory tests  Not scope of LOINC 1. The instrument used in testing 2. Fine details about the sample or the site of collection (e.g., upper right plural) 3. Who verified the result 4. The size of the sample collected 5. The place of testing (e.g., home, bedside, clinical lab)
  19. 19. Thai Health Information Standard Development Center(THIS)Thai Health Informatics Academy Conclusions & Discussions • Limitation of mapper knowledge domain  Laboratory experts knowledge could increase accuracy mapping results
  20. 20. Thai Health Information Standard Development Center(THIS)Thai Health Informatics Academy Conclusions & Discussions  More than 80% mapping result indicate LOINC is applicable to Thai healthcare service  High number of 1-Many indicate LOINC has higher details than local tests
