  1. Data Aggregation, Liquidity, andthe Learning Healthcare System: Perspectives from the Indiana Experience Shaun J. Grannis, MD, MS, FACMI, FAAFP Biomedical Informatics Research Scientist, The Regenstrief Institute Associate Professor of Family Medicine, Indiana University School of Medicine

  2. What We’ll Cover The Context The Problem Potential Solutions

  3. Regenstrief Institute Endowed by Sam Regenstrief - Inventor of the low cost front-loading dishwasher Supported the creation of the Institute to apply process improvement to medicine A medical informatics “skunkworks”

  4. Regenstrief Informatics - What We Do Build medical information systems Study systems and supporting technologies Rationalize, organize and standardize health care data Pragmatists - needs driven, create solutions to real-world problems Describe what works and what doesn’t

  5. High Costs and Inefficiencies • Very large and inefficient information enterprise that still operates with substantial amounts of paper • Costs are rising • $2.4 Trillion in 2009, ~$8,000/person • Growth outpacing inflation • Now $2.7 Trillion in annual spending (2012 est.) • May reach $4 Trillion by 2020 (!) 1.

  12. Notifiable Condition Detection

  13. System Overview: Notifiable Condition Detector E-mail Summary Abnormal flag, Organism name in Dwyer II, Value above threshold Realtime Compare to Dwyer I Daily Batch To Public Health Reportable Conditions Databases Inbound Message Potentially Reportable Reportable Condition To Infection Control Record Count as denominator Print Reports

  14. ELR Completeness 4,785 total reportable cases INPC– 4,625 (97%) Health Dept – 905 (19%) Hospitals – 1,142 (24%)

  15. Timeliness ELR identified cases 7.9 days earlier than did spontaneous reporting.

  16. Prepopulated Reporting Forms

  17. Clinical Messaging/Public Health Communication

  18. Sample Pre-populated Reporting Form

  22. Pre-populated form Information flow

  23. Outcome measures Time-to-treatment Timeliness of reporting to public health Completeness of reporting data Level of communication among PH and clinical providers

  24. Syndromic Surveillance

  33. All Health Care is Not Local: An Evaluation of the Distribution of Emergency Department Care Delivered in Indiana

  34. All Health Care is Not Local Over 3 years, 2.8 million patients totaled 7.4 million visits for an average of 2.6 visits per patient. More than 40% of ED visits during the study period were for patients having data at multiple institutions. This population analysis suggests a pull model is necessary, and helps inform the ongoing dialog regarding the merits of peer-to-peer (push) and federated aggregate HIE (pull) NwHIN architectures.

  35. Leveraging Analytics to Enable Accountable Care • Patients receive healthcare from multiple providers and across organizations • More than 40% of ED visits are for patients having data at multiple institutions A network diagram illustrating the connectedness among Indiana EDs that participate in PHESS. Circular nodes represent EDs; node size indicates the visit volume; node color indicates the centrality of the ED. The gray edges connecting nodes indicate where patient crossover occurs. EDs that share proportionally larger number of patients are clustered together. While general clusters of “medical trading areas” emerge, the myriad gray edges clearly illustrate how interconnected all EDs are to one another.

  36. Distribution of patients stratified by the total number of ED visits. Note that six patients visited the ED more than 300 times and a single patient accumulated 385 visits for the 3-year study period.

  37. Shifting nonurgent visits from ED to primary care: During the 6-month trial with 9 Central Indiana hospitals, the 320,000-member managed health plan reduced nonurgent ED visits among members served by these hospitals by 53 percent, while simultaneously increasing primary care office visits by 68 percent. • Cost savings: The shift from ED to primary care visits that occurred during the pilot test saved the health plan an estimated $2 to $4 million over the 6-month period. http://www.innovations.ahrq.gov/content.aspx?id=3988

  38. 84% PPV for predicting which patients who will use ED > 16 times in two years.

  39. Supporting ACO Services • Care management support • HIE Information matched to CMS defined ACO population • Patient care summaries extracted • Delivered to ACO care management systems via CDA documents • Readmission risk stratification (LACE model) • Adaptation underway

  40. Integrating socio-behavioral determinants of health using geospatial information Patient Address Change 1 ADT Processor 2 Update person_address table with new address information person_address table 6 • In real-time, Address Update Detector detects and writes address changes to the post_processing table 3 post_processing table Geo-Coding Application Address Update Detector Call Polis Center web service which returns geo-coded addresses 4 5 Geo-Coding app reads the post_processing table Polis Web Service Comer KF, Grannis S, Dixon BE, Bodenhamer DJ, Wiehe SE.

  41. Improving Efficiency of Data Integration

  42. A Cautionary Note: the Era of “Big Medical Data”, Analytics, and Data Quality

  43. Aggregate Data Example:Diabetes and Obesity Cohort “Coders should pay attention to the BMI because it makes a difference in terms of reimbursement […]. A BMI of 40 or higher - diagnosis code V85.4 - is considered a complicating condition, meaning higher reimbursement when reporting this code along with the appropriate principal diagnosis.” (http://medicalcodingpro.wordpress.com/page/2/) Data often reflect financial incentives, not the true population distribution.

  44. “Using Information Entropy to Monitor Chief Complaint Characteristics and Quality”

  45. Data Quality Missing data rate for a sample of clinical transactions received by the INPC in 2008. Supplemental data is often necessary to enhance practice based population health processes
