HIT Asthma. A tale of woe & enlightment,

  1. 1. H IT A s t h m a www.CenterForUrbanHealth.org a t a l e o f wo e a n d e n l ig h t e n me n t Yiscah Bracha, M.S. ybracha@CenterForUrbanHealth.orgAHRQ Annual Meeting09SEP08
  2. 2. P r o je c t O b je c t iv e : www.CenterForUrbanHealth.org• Demonstrate use of HIT to improve ambulatory asthma care• Two existing technologies:  Interactive Asthma Action Plan (IAAP) (developed by MN Dept of Health)  Commercially available electronic health record (EHR) (EpicSystems Inc.)
  3. 3. Wha t w e k ne w : www.CenterForUrbanHealth.org• For asthma, IAAP beats Epic in user and patient friendliness• Difficult for Epic user to get to IAAP• Untapped potential to use EHR data to support QI
  4. 4. Wha t w e w a nte d to propos e : www.CenterForUrbanHealth.org• Make IAAP available from within Epic- driven workflow  Brings guidelines to the point of care• Use IAAP database as asthma registry  Evaluate effect of QI initiatives  Identify at-risk patients  Generate reports required by external agencies
  5. 5. O n e s m a ll p r o b le m … www.CenterForUrbanHealth.org• Existing IAAP based on guidelines released in 2002• 2007 guidelines soon to be released• Our project would link the EHR system to a soon-to-be-obsolete tool
  6. 6. W h a t w e a c t u a lly propos e d: www.CenterForUrbanHealth.org• Update IAAP to be consistent with 2007 guidelines• Make updated IAAP available from within Epic- driven workflow  Brings new guidelines to the point of care• Use IAAP database as asthma registry  Evaluate effect of QI initiatives  Identify at-risk patients  Generate reports required by external agencies
  7. 7. E x p e c t e d c h a lle n g e s www.CenterForUrbanHealth.org• Accessing IAAP from Epic  Pushes boundaries both technically & organizationally• Creating & using asthma registry  Technology well-understood; organizational barriers to readiness• Updating IAAP  Trivial technically; no impact organizationally
  8. 8. 3 m o n t h s a f t e r p r o je c t in c e p t io n : www.CenterForUrbanHealth.org• IAAP-EHR interface:  Technical boundaries identified  Organization is ready within those boundaries• Registry  Organizational barriers quickly overcome  Demanding to establish what fields to pull, but a well-understood task.• Update IAAP ….
  9. 9. F a m o u s la s t w o r d s : www.CenterForUrbanHealth.org• “It will be simple to update the existing IAAP to make it consistent with the new guidelines”
  10. 10. Oops : www.CenterForUrbanHealth.org• Original IAAP contained:  Out-of-date, unsupported version of Java  Database not designed to support analysis  List of meds not designed to be updated• “Update” of any kind not possible  Radical shift in perspective from 2002 to 2007  FROM: Treating acute symptoms  TO: Managing chronic disease
  11. 11. T h e s t r u g g le : www.CenterForUrbanHealth.org• Clinicians try to convert guidelines directly into screens:  They get trapped in logical circles from which they cannot escape• Analytically-minded Project Director tries to display their thinking in flow diagrams  Clinicians can’t follow the diagrams• Many expressions of frustration exchanged!
  12. 12. S ome c onc e rns : www.CenterForUrbanHealth.org• Close scrutiny of guidelines reveals:  Ambiguous and/or internally inconsistent recommendations:  Inadequate dosing instructions for young children  Recommendations for formulations not available commercially  Recommendations for off-label uses of drugs  Drugs for young children not approved by FDA
  13. 13. More c onc e rns : www.CenterForUrbanHealth.org• Even with close scrutiny, no answers to front-line clinical questions:  What should the dosing instructions be in the “red zone” of the asthma action plan?  How can we determine the current treatment step for a new patient who is already receiving asthma care?
  14. 14. A n d m o r e s t r u g g le s : www.CenterForUrbanHealth.org• Enormous effort required to communicate needs to software development company• Even with that effort, still uncertainty that they really understand what’s required
  15. 15. T h e t a le o f w o e … www.CenterForUrbanHealth.org• We are failing at our most trivial task  AHRQ will give up on us  We will disappoint the users whose expectations we have raised• We have over-extended ourselves and our budget trying to cope with this• If we succeed, who will be responsible for harm that may arise because we delivered vague guidelines to the point of care?
  16. 16. T h e t a le o f e n lig h t e n m e n t : www.CenterForUrbanHealth.org • Bob* (unexpectedly) says:  This is very interesting!  Let’s reduce your anxiety … there are lots of ways to make lemonade here  We have an agency interest in alternative ways to disseminate guidelines  Document these issues  Analyze them  Make recommendations to future expert panels* Bob Mayes, our AHRQ Task Order Officer
