Overview
 Epidemiology
 The
allure of tobacco
 Physicians’ role
 Treatment strategies
 Bribery
 Health Care Reform
It’s Common
45 million adults smoke in
the U.S. (2006 estimate)
 21% of the U.S. adult
population
 Rate highest among 18-44
year-olds at 25%

It’s deadly!
From 2000-2004, smoking
resulted in an annual
average of 443,000 deaths
in the United States.
 This is the equivalent of
the deaths of all the
residents living in Kansas
City, Missouri per year

Annual smoking attributable mortality, years of potential life lost, and economic costs—United
States 2000-2004. Available online at: www.cdc.gov/mmwr/preview/mmwrhtml/mm5425a1.htm.
The breakdown:
Lung Cancer = 29%
CAD = 28%
COPD = 21%
Other Cancers = 8%
Stroke = 3.6%
It’s expensive!
$194 billion/ year in
economic losses in the
U.S. due to smoking
 GDP of Israel in 2008
 $97 billion a year in lost
productivity
 $97 billion spent each year
in heath care costs

The Allure…
 Nicotine!
 Binds
to the nicotinic acetylcholine receptors in the
brain, releasing dopamine and beta-endorphins
 Results in euphoria and relaxation
 Also acts as a stimulant, releasing norepinephrine
and epinephrine into the bloodstream
Wait, why would you want to quit?
 Increased
coagulation (platelet adhesion)
 Vasoconstriction, accelerated atherosclerosis
 Bronchospasm
 Insulin resistance**
 CNS irritability, sleep disturbance
 Cancer: Lung, Head and Neck, Cervical, Bladder
 Emphysema, chronic bronchitis

Physicians’ Role
 Do
we make a difference? YES!
 Brief physician counseling resulted in 56%
increase in smoking cessation compared with
patients who were not counseled at all
 Odds
of quitting: 1.56, CI 1.32-1.84
 Pharmacotherapy
and counseling together increase
patients’ odds of quitting substantially
Lancaster T. Cochrane Database Syst Rev. 2005;(2):CD001292.
How do you broach the subject?
 US
and UK guidelines suggest using the “5 A’s”:
 Ask
your patients about tobacco use
 Advise them to stop smoking
 Assess your patient’s motivation (stage of change) and
need for pharmacotherapy
 Assist with prescriptions and referrals to behavioral
support programs
 Arrange for follow- up on their progress.
Srivistava P, et al. BMJ 2006;332:1324-1326.
Stages of Change Model
 Pre-contemplation–
“Ignorance is bliss”
 Contemplation– Ambivalent about change
 Preparation– ** Planning to act **
 Action– Actively participating in behavior change
 Maintenance– Sustained behavior change
 Relapse– “Fell off the wagon”
Prochaska JO. Am Psychol 1992;47:1102-4.
Types of Treatment

 Only
cold turkey”
5% chance of quitting at 1 year
 Nicotine
replacement
 Antidepressants
 Bupropion
(Zyban, wellbutrin)
 TCAs, SSRIs
 Partial
Nicotine receptor agonists

do I go from

 Not able to perform
statistical analysis– studies
variable

1998;(2)CD001008.
What about bribery?
 Study
of 878 corporate employees
 Randomized to information on smoking cessation
or financial incentives for smoking cessation
 Patients given $100 for completing a course, $250
if tobacco-free at 6 months, and $400 at 12 months
 3 times greater quit rate in those being paid at 9-12
months after enrollment (14.9% vs 5.0% p < 0.001)
Volpp KG, et al. NEJM. 2009;360(7):700-709.
Health Care Reform
 Expands
coverage to 32 million Americans
 Provisions to close Medicare Part D donut hole
 “Patch” to maintain Medicare reimbursement to
Physicians adjusted for inflation/cost of living
 Will it include reimbursement for smoking
cessation or other behavioral change counseling?
 No–
would have to reverse entire payment system to
value prevention over procedures
Take home points
 You
can make a difference!
 Five A’s
 Focus your attention on those in the planning stage
 If you can’t pay your patients– prescribe!
 NRT
plus bupropion
 Varenicline – maybe?
 Nortriptyline
Thank you!
