Presentation summary

> Background

> Minnesota quitline collaboration

> Clinic fax research questions and methodology

> Clinic fax referral pilot findings

> Statewide rollout

4

Why this matters

>Tobacco use is the leading preventable cause of death

>Tobacco use causes $2 billion in health care costs in Minnesota each year

>Current smokers have 16% higher health care costs

5

Comprehensive approach to prevention

6

The challenge

> Use of telephone quitlines is low

> Earlier recruitment done with media promotion– Advantages– Disadvantages

7

Innovations

> Use health plan systems to connect smokers to quit lines– Referrals from disease management, prenatal program, etc.– Pharmacy benefit management system (SCRIPS)– Pay for Performance (Recognizing Excellence)

Clinical Background

> Tobacco use is a chronic medical condition

> Brief interventions are effective, but more intensive interventions are:– More effective– More cost-effective

> Arranging follow-up after the office visit is a particular challenge

> Referral to telephone counseling is an easy way to provide follow-up – Phone counseling increases the odds of successful

quitting by 50-70%

10

Clinics and quitlines

> Fewer than 2% of tobacco users in the U.S. use quit line services– Media promotion is needed to encourage calling – Many states offer fax-referral programs, but they are often

underutilized by health care providers

> Multi-faceted interventions improve performance– Systems changes– Leadership– Outreach – Feedback– Incentives

The Clinic Fax program

> Builds on a successful collaboration with Minnesota’s Health Plans and ClearWay Minnesota– Successful coordination since 2002– Direct to provider education and mailings

> Minnesota Clinic Fax Program - Centralized Triage System – Clinical referral mechanism for ALL Minnesotans – Led and designed by Blue Cross– Jointly created materials, forms and information

13

Clinic Fax referral process

Fax Referral

Patient fills out fax referral, staff create EMR order for smoking cessation and obtain verbal consent

Designated staff fax referral/EMR to Central Triage

Feedback to clinic on result of patient contact

Tobacco status assessed and asked if interested in quitting

Quit line contacts patient

14

Clinic Fax referral form (Paper/EMR)

> Clinic information– Pre-populated clinic address and contact– Health care provider

> Patient information– Minimum necessary contact information– Health plan check boxes– Release authorization– Patient signature

> Clinic Feedback– Contact date– Outcome (enrolled, declined, not reached)

15

Compliance and confidentiality

> HIPAA Approved Referral Form– Minimum necessary– Collaborator approved– Cover letters

> Aggregate Data Only– By clinic

> De-identified Referrals – Health plan identity removed from reports

16

Research questions

> What is the feasibility of establishing an integrated clinic fax referral system in Minnesota?

> What is the effect of financial incentives on the rates of physician referral to a state tobacco quitline?

17

Other research questions

– Which clinics respond the most to the incentive?

– Does the offer of financial incentives influence the appropriateness of the referrals?

– What is the cost per additional referral or enrollee?

18

Methodology

> Setting: Fairview Physician Associates (FPA)– Large multi-specialty group providing both primary

care and specialty care in Minnesota– A total of 49 clinics provide adult primary care services

and record tobacco use as a vital sign

> Dates: September 1, 2005 – June 31, 2006

19

Methodology

> Design: Two-group randomized design– Usual care (feasibility) n=25 clinics

> Information and materials mailed to clinics> EMR modified to allow electronic “fax” referral

– Intervention (n=24 clinics)> Launch meeting> Monthly feedback> Financial incentives

– $5000 bonus for clinics referring at least 50 patients during the study period– $25 for each referral past 50

20

Methodology

> Measures– Primary outcome: percentage of smokers referred

to phone counseling– Clinic characteristics– Costs

> Analysis– Unit of analysis: clinic (n = 49)– Primary comparison: 2-sided t-test– Secondary analysis (clinic characteristics): 1- and 2-way

Conclusions

> A fax referral system is feasible (4.2% of smokers referred in usual care clinics)

> Incentives increased referral rates (11.4% vs. 4.2%)

> Incentives appear to be the most beneficial for the majority of clinics with less QI engagement

> No evidence of “gaming the system”

> Cost per caller comparable to media promotion of tobacco quit lines

29

Statewide rollout

– October 1, 2007 program launched statewide– Incentive based on enrollment thresholds– 610 clinics registered as of December 2008 – 260 (42%) of sites are participating in

Recognizing Excellence– Average of 310 referrals a month
