  1. Context Integration of EMR and PACS Increases Radiologist Use of EMR John Mongan, MD, PhD David Avrin, MD, PhD Department of Radiology, UC San Francisco

  2. PACS-EMR Context Integration • Clinical history essential for accurate interpretation * EMR data changes interpretation in 6% of cases 1 • EMR historically separate from PACS • Context integration opens same patient in PACS, EMR 1. Franczak et al. Health Aff. 2014 May;33(5):800–6.

  4. Why doesn’t everyone have integration? • $$$ • < 50% adoption even in academic centers 1 • No quantitative data on benefits 1. Forsberg et al . J Am Coll Radiol. ePub ahead of print 2016 Mar 22

  5. Does integration provide quantifiable benefit? • Context integration implemented at UCSF in August 2014 • Does integration save radiologist time? • Does integration increase radiologist use of EMR?

  7. Data collection • EMR usage data obtained from security audit logs * Trainee accounts on active clinical service across sample period * “Summary report” and protocol module accesses removed * Non-clinical accesses removed • Study volume data obtained from report database • Sample period 180 days prior, 180 days post (following 60 day run-in)

  8. Events collected • 37 users • 51,926 studies • 21,018 EMR accesses

  13. Impact of time savings • Each EMR access 46 seconds faster • Multiplied by average number pre-integration accesses, extrapolated to one year • Integration saves over 8 hours per radiologist per year

  14. Impact of increased EMR usage • 8.2 percentage point increase in EMR access • EMR data changes interpretation in 6% of cases 1 • Integration changes 1 read in every 200 cases 1. Franczak et al. Health Aff. 2014 May;33(5):800–6.

  15. Conclusion • PACS-EMR integration achievable with software available today • Integration saves time and likely improves accuracy • Effects are durable and self-reinforcing • EMR integration should be considered an essential feature of a PACS workstation
