The Everett Clinic • Physician owned and managed multi-
specialty integrated health-system with a 83-year history
• 14 locations; 60+ clinics• Ancillary services• 260 physicians/ 1,500+ employees• 225,000 patients• 700,000 ambulatory visits annually• 2.5 million Rx annually
![Page 3: Implementing an e-Prescribing System: A Journey, Not a Solution EB Devine, JL Wilson-Norton, NM Lawless, W Hollingworth, RN Hansen, BA Comstock, AW Fisk,](https://reader030.fdocuments.in/reader030/viewer/2022020417/56649f2f5503460f94c48ae9/html5/thumbnails/3.jpg)
• CliniTech Information Resources• Internally-developed EHR began in 1995: charts, labs
and imaging reports• e-prescribing implemented beginning during 2003-05• Features of e-prescribing system
– Web-based– Write new & refill prescriptions – Output = fax/ print– Optimizes choice of medication; generates medication list as
prescriptions are written– Pediatric antibiotic dosing by weight
• Utilizes subscription to commercial drug database as back end
• Builds patient drug database, improving disease management
The Everett Clinic’s e-prescribing system
![Page 4: Implementing an e-Prescribing System: A Journey, Not a Solution EB Devine, JL Wilson-Norton, NM Lawless, W Hollingworth, RN Hansen, BA Comstock, AW Fisk,](https://reader030.fdocuments.in/reader030/viewer/2022020417/56649f2f5503460f94c48ae9/html5/thumbnails/4.jpg)
Implementation of e-prescribing• Several months in development
– Accuracy and relevance of drug database– Screens easy to use and involve minimal manipulation– Basic decision support
• Adopt an icon = “MedMan”• Implement at pilot site; refills first• Voluntary use• Goal: Implement on platform of wireless laptop • Switch to hardwired desktops in exam rooms –
– 505 exam rooms!
• 51 months to last clinic go-live• Now: 5,000 prescriptions/ day (95% written); faxed to 600+
pharmacies• Transition to vendor-purchased EHR in late 2007 – CDS
customized; use becomes mandatory

• Capture lessons learned during implementation• Evaluate impact on medication errors and
adverse drug events • Measure impact on workload / workflow
– Time-motion study– Process metrics (chart pulls, prescriptions written)
• Evaluate impact on human factors– Focus groups– Survey assessing readiness to adopt IT
AHRQ HIT Grant:Specific Aims
![Page 6: Implementing an e-Prescribing System: A Journey, Not a Solution EB Devine, JL Wilson-Norton, NM Lawless, W Hollingworth, RN Hansen, BA Comstock, AW Fisk,](https://reader030.fdocuments.in/reader030/viewer/2022020417/56649f2f5503460f94c48ae9/html5/thumbnails/6.jpg)
Implementation Lessons (1)• Culture
– Visionary leadership; safety-oriented; positive, upbeat work environment
• Two-way communication constant• Iterative implementation• Re-engineering / standardization of workflow integral to
process • Adequate investment in infrastructure a priori; speed is
essential for adoption• End-user prior experience variable and influences user
attitudes• Adequate testing and feedback • Just-in-time, one-on-one training; 24 / 7 help
![Page 7: Implementing an e-Prescribing System: A Journey, Not a Solution EB Devine, JL Wilson-Norton, NM Lawless, W Hollingworth, RN Hansen, BA Comstock, AW Fisk,](https://reader030.fdocuments.in/reader030/viewer/2022020417/56649f2f5503460f94c48ae9/html5/thumbnails/7.jpg)
Implementation Lessons (2)
• Use early adopters as trainers• Users interested in research results as motivation for
adoption– Medication safety, workflow / workload– Focus groups provided opportunity to provide
feedback• Retail pharmacies are stakeholders, too• Patients love looking at their data with their physician• Many exam rooms not large enough for computer
– Need retrofitting
• Maintenance includes ongoing monitoring and development of plans for system downtime
• Customization of purchased system – With great care; detailed work
![Page 8: Implementing an e-Prescribing System: A Journey, Not a Solution EB Devine, JL Wilson-Norton, NM Lawless, W Hollingworth, RN Hansen, BA Comstock, AW Fisk,](https://reader030.fdocuments.in/reader030/viewer/2022020417/56649f2f5503460f94c48ae9/html5/thumbnails/8.jpg)
Medication error study
• Aim – Evaluate the impact of e-prescribing on medication
errors and adverse drug events (ADEs) – Capture error characteristics and severity
• Methods– Pre-/ post- study– Retrospective review, 10,000 scripts (3,000 for pilot
study at 1 internal medicine clinic) – Adopted definition and severity index of the NCC MERP1
– Data sources: prescriptions, EHR, laboratory values, hospital admit / discharge / emergency department notes

Time-motion study• Aim
– Evaluate whether the implementation of e-prescribing was at least time-neutral for physicians and staff members
• Methods– Shadowed each user over
a 4 hour shift – 8am -12 noon, or 1pm-
5pm– With consent of clinician &
patient
•Data collected with Timer ProTM (http://performance-measurement.com)
•Categories adapted from Overhage

Focus group study
• Aim– Explore and describe prescriber & staff experiences
with and perceptions of the e-prescribing system
• Methods– Qualitative research– Universal sample in 3 clinics / 3 stages of
implementation– 30 minutes/ group; 3-8 participants; oral consent– Semi-structured elicitation techniques
• 4 domains – expectations, impact, fears, barriers to adoption
– Analysis with Atlas.ti software
![Page 17: Implementing an e-Prescribing System: A Journey, Not a Solution EB Devine, JL Wilson-Norton, NM Lawless, W Hollingworth, RN Hansen, BA Comstock, AW Fisk,](https://reader030.fdocuments.in/reader030/viewer/2022020417/56649f2f5503460f94c48ae9/html5/thumbnails/17.jpg)
Focus group results•8 focus group; 67 participants (17 prescribers; 52 RNs & MAs)•Computer background influenced perceptions
10 Themes - Perceptions of e-prescribing system
Benefits Accuracy, transparency, integration
Downsides Programming errors; lack of wireless reliability
Efficiency Increased after training period
Expectations Streamline work
Fears Yes, at paper-based clinic
Desired features Prescribers – CDS alerts and favorites lists
Impact Prescribe from home – an unexpected impact
Impressions “I love it!”
Leadership Training, feedback, support
Safety Improved

Research Conclusions•The Everett Clinic / University of Washington a valuable partnership•Medication errors
•e-prescribing reduces medication errors •eliminates types of errors (illegibility, abbreviations)•introduces new types of errors (picking errors)•standardizes care / reduce unnecessary variation•data available to optimize quality & lower cost of prescribing
•Time-motion workload / workflow •e-prescribing has minimal impact on prescriber time (12 seconds per event)
•Workload •95% of prescriptions written electronically•Number of monthly chart pulls decreased from
•5,800 (2003) to 650 (2007) – 9-fold reduction •Focus groups
•impact beneficial – users do not wish to go back to paper-based prescribing
