Slide 3

Background

• Promise of e-prescribing:
  • Improved safety.
  • Value.
  • Efficiency.
• Slow spread to community-based practices:
  • Uncertain what drives successful e-prescribing uptake in community setting.

Slide 4

Study setting

eRx Collaborative: Blue Cross Blue Shield of Massachusetts; Neighborhood Health Plan; Tufts Health Plan; DrFirst; Zix Corporation

• Initiated by BCBSMA and Tufts Health Plan.
• Partnered with ZixCorp, providing physicians with PocketScript system.
• Program began in early 2004.

Prior studies—e-rx and costs

Slide 7

Prior studies—e-rx and safety

• Most alerts over-ridden by prescribers (Weingart et al. Arch Int Med 2003)
• Reviews suggest reduced ADEs, but inadequate studies in outpatient setting (Ammenwerth et al. JAMIA 2008)

Slide 8

Study questions

• What is the experience of community-based practices that adopt electronic prescribing systems?
• What barriers remain to successful adoption and use of e-prescribing?
• Where has e-prescribing succeeded; has it created new problems?

Slide 9

Study design

Focus groups:

• Conducted spring 2008.
• Prescribers and office staff:
  • Internal medicine, pediatrics, FP, cardiology, nephrology.
• Both current and former users:
  • High/low volume, abandoned, transitioned to electronic medical record (EMR).

Interviews:

• Detailed discussions with prescribers.

Slide 10

Findings

• E-prescribing positives.
• Ongoing challenges/barriers.

Slide 11

E-prescribing positives

• Prescription security.
• Financial gain.
• Office efficiency.
• Medication safety.
• Insurance issues.
• Communication with pharmacy.

Slide 12

E-prescribing positives (continued)

Prescription security:

• Less people touch the actual prescription.
• Patients cannot lose the prescription.
• Patients cannot tamper with prescription.

Slide 13

E-prescribing positives (continued)

Financial gain:

• Direct incentives a major factor:
  • Initial adoption subsidized.
  • Later incentives for ongoing use.
• Potential gains in patient satisfaction:
  • "If we can reduce wait times, we've succeeded."
  • Unclear of ROI in terms of practice billing.

Slide 14

E-prescribing positives (continued)

Office efficiency:

• Major changes in practice workflow:
  • Less calls for front-end staff.
  • Refills and other non-critical medication issues can be batched for MD review.
• Frees staff time and attention:
  • Less interruption of work.
  • Pharmacy information is updated and accurate.
  • Perceived ROI, but hard to quantify.

Slide 15

E-prescribing positives (continued)

Medication:

• Quick review of patient medication history:
  • Available round the clock, out of office.
• Alerts about drug-drug interactions:
  • Office staff appreciated reminders.
  • Physicians less certain, many alerts dismissed.
• Ability to identify patients on a specific drug:
  • Especially useful for recalls:
    • "I can identify all the patients on..."

Slide 16

E-prescribing positives (continued)

Insurance issues:

• Can see if a drug is not covered:
  • Avoids callbacks, increased patient satisfaction.
• Ability to identify patients on a specific drug:
  • Also useful for prescribing incentive programs.

Slide 17

E-prescribing positives (continued)

Communication with pharmacy:

• Timely flow of information.
• Ability to send specific messages.
  • E.g.: "No more refills until patient sees doctor."

Slide 18

Ongoing challenges/barriers:

• Learning curve.
• Usability.
• Reliability.
• Safety concerns.
• Patient resistance.
• Data security.

Slide 19

Ongoing challenges/barriers (continued)

Learning curve:

• New skill: "not covered in medical school."
• Difficult for older prescribers.
• High burden on champions/superusers.
• New tasks for some personnel—source of resistance.
• Lack of support.
• "Locked in" with initial vendor choice.

Slide 20

Ongoing challenges/barriers (continued)

Usability:

• Types of devices/interfaces.
• Problems with some pharmacies.
• Inability to transmit to PBMs.

Reliability:

• Connectivity/network problems, loss of productivity.
• Resistance for sick patients or weekends.

Slide 21

Ongoing challenges/barriers (continued)

Safety concerns:

• Selecting wrong patient.
• Selecting wrong drug (Cipro/Cialis).
• Some doses/formulations not in system.
• Drug alerts not perceived as helpful: "ignore almost all."
• Some alerts may be handled by non-prescribers in the process of queuing.

Slide 22

Ongoing challenges/barriers (continued)

Patient resistance:

• Wanting something in hand (older pts).
• Bad experiences with failed transmissions.
• Inability to transmit to PBMs.

Data security:

• Concern about whether transmitting patient data creates liability exposure.
• Concern about prescribing data and tracking/profiling.
• Who owns the data: cost of changing.

Slide 23

Summary observations:

• Overall positive experience—almost none would "turn back the clock."
• Successes: office efficiency, pharmacy communication, formulary information, prescription security.
• Barriers/challenges: learning curve, reliability, questionable safety impact.

Slide 24

Summary observations (continued)

Benefits more apparent in larger practices with high volume of chronic mediations.

• More opportunities to streamline workflow.
• Prescription volume/management is seen as a major issue at baseline.
• Possible financial gains easier to perceive.

Slide 25

Next steps

• On-site visits to observe system use, validate focus group observations.
• Large-sample survey to test generalizability of initial findings.
• Quantitative studies of e-rx impact on cost, safety, adherence, clinical outcomes.
