6. By 1985 it had evolved into this 5/9/20142014 KBPRN Collaborative Conference

7. Concerns over Data Accuracy  1985-Devin and Murphy of IBM  Development of architecture for data warehousing  Focusing on high quality, historically complete data, and accurate data 5/9/20142014 KBPRN Collaborative Conference

8. “Big Data”  July 1997  The Problem of Big Data  The term "big data" was used for the first time in an article by NASA researchers Michael Cox and David Ellsworth.  The computer processing cold not keep up with the increase in the large amount of data being generated. 5/9/20142014 KBPRN Collaborative Conference

9. Big data in health care  Knowledge translation between health analytics and the realities of patient care  The statement ‘There are right ways to analytics’ implies we may not be doing analytics correctly  Health care seems to think that big data will improve patient care and population health management  It isn’t about the data and how much you have, but about data management  We are creating data landfills  Turning data into useful information

10. The beginning of Electronic Health Records-1964 http://www.youtube.com/watch?v=t-aiKlIc6uk

11. So what were the promises from this 1964 experiment  Relieve doctors and nurses of some of their paperwork  Better management of diseases  Eliminate errors in medication and tests

12. What is current status  The promise of EHR’s  Have reduced paperwork  Reduced errors in patient medications and testing  Are we making best use of the data  Do we have good tools-software and skilled analyst 5/9/20142014 KBPRN Collaborative Conference

13. Some examples of using EHR data  Example 1 – Patients with last HbA1c >=9  Example 2 – Losing QI incentive pay  Example 3 – Identifying patients with hypertension 5/9/20142014 KBPRN Collaborative Conference

14. Example 1 – Patients with last HbA1c >=9 (HRSA report)  Report showed 85%  Nurse responsible for QI at site questioned data  We found that only the hand-entered results from their in-house labs were picked-up (HRSA treats patients with missing HbA1c as >=9; missing data treated as non-compliant)  Lab reports from outside vendor were missed  True statistic = 7% 5/9/20142014 KBPRN Collaborative Conference

15. Example 2 – Excess prescription of antibiotics among children without proof of bacterial infection  Automated report on children receiving antibiotics showed excess prescribing among providers  Prescribing antibiotics for viral infections  Report was missing the diagnoses that should have been tied to the prescription  Automated report did not match the appropriate diagnoses with the prescriptions  Loss of $20,000 in incentive pay 5/9/20142014 KBPRN Collaborative Conference

16. Example 3 – Identifying patients with hypertension  Worked with 11 primary care centers on under- diagnosis of hypertension  Identified patients based on ICD-9 coding  Noticed significant use of free text coding (the EHR allowed providers to use free text)  Found significant amount of patients with consistently high blood pressure readings but no diagnosis of hypertension (EHR missed this biomarker)  Found nearly 2000 patients missed across all sites 5/9/20142014 KBPRN Collaborative Conference

18. John Snow and the Broad Street pump  John Snow’s chemical and microscopic examination was not able to conclusively prove the danger of the Broad Street pump.  Snow created a map to show how the cholera cases were clustered around the pump.  Pump handled removed upon new conclusion 5/9/20142014 KBPRN Collaborative Conference

19. John Snow Revisited  How could electronic health records have help…?  EHR identifies all cases of cholera  Look at location indicators (addresses)  Create thematic map  Removed pump handle 5/9/20142014 KBPRN Collaborative Conference

20. Identifying patients at-risk for diabetes  Previously, relied on provider intervention at point of care to identify diabetes risk and think/make effort to refer the patient  One patient at a time  Inefficient  Identify at-risk patients using existing data  Clinic-wide  More efficient 5/9/20142014 KBPRN Collaborative Conference

22. Using de-identified data from 14 WV primary care centers, we did the following:  Standardized the data in a common format (CDEMS)  Identified established patients by site (those receiving care for 12 months of more)  Excluded patients with a diagnosis of diabetes or pre- diabetes  Identified persons at risk for pre-diabetes based on CDC’s Group Lifestyle Balance criteria:  Age > 45 with last recorded BMI >25  Age 25, with HTN, hyperlipidemia, gestational diabetes, family history of diabetes, or cardiovascular disease  Last fasting blood glucose in the range of 100-125 5/9/20142014 KBPRN Collaborative Conference

23. Identifying patients Identified persons at risk for pre- diabetes based on CDC’s Group Lifestyle Balance criteria:  Age > 45 with last recorded BMI >25  Age 25, with HTN, hyperlipidemia, gestational diabetes, family history of diabetes, or cardiovascular disease  Last fasting blood glucose in the range of 100-125

24. Results  14 primary care centers:  130,021 active patients  106,367 (81.8%) are established (receiving care for 12 months or more)  94,283 (88.6%) do not have a diagnosis of diabetes or pre-diabetes  Those patients are the focus of the analysis 130,021 active 106,367 established 94,283 no dx of DM or pre-DM

25. Results-Identifies 10,673 (11.3%)

26. Discussion  Patients at-risk for pre-diabetes and in need of targeted screening can be identified using EHR data  Streamlines opportunity for patient identification, screening, and referral  No need for additional data collection at the sites  Making meaningful use of existing data 5/9/20142014 KBPRN Collaborative Conference

27. Discussion  Early identification and intervention  opportunity for prevention  Improving outcomes and quality of life, and reducing long-term costs of care  Implementation highlights  Algorithms built using de-identified data  Identified data used to create lists of at-risk patients at individual sites  Each site contacted patient in an effort to recruit them for intervention 5/9/20142014 KBPRN Collaborative Conference

28. Questions or comments

29. Some closing comments  At one time there were 450 different EHR’s in country  EHR’s need better Import/Export functions  Common Import/Export data formats  Should EHR’s be permitted to charge extra for analytics  EHR’s charge for each site to be connected to state Information Exchanges ($10,00)
