  2. Group Health and the HMORN HMO Research Network Large text repositories Common EMR platforms

  3. HMORN-based research proposal Douglas A. Corley, MD, PhD, MPH, Kaiser PermanenteAHRQ PROSPECT: Clinical Infrastructure for Comparative Effectiveness Research

  4. HMORN-based research proposal • Score: “Very good” (but not fundable) • Strengths of the application include: • expands on an existing network • builds upon databases with pathology and endoscopy results • unique linkage of pathology reports to existing databases • ... notably, using NLP tools (caTIES) to extract data from pathology reports for CER • Overall, a good first attempt at an HMORN-wide implementation

  5. Progress, Emerging Opportunities Current pathology repository • Counts, accumulation rate • 522,740 reports (1/17/2011) • +81,924 since 1/27/2010 (+1,500/wk) • Also coding w/ SNOMED (UIMA/cTAKES) • Full text indexed repository • Google-like exploration • Reformatting, data warehousing project • Re-extract text from HL7 (Spring 2011) • Add CUIs to Virtual Data Warehouse

  6. Progress, Emerging Opportunities • Next multi-site HMORN-based proposal? • Pathology as “gateway” for local NLP • Deployment is a reach in many applied settings • Security Roundtable for Cloud-Deployed Clinical NLP • Seattle, May 22-23, 2011 • Local security issues
