smoking in perspective
Smoking in Perspective
  • Kills more than 440,000 Americans each year
  • 23% of adult Americans smoke
  • 3,000 children and adolescents become regular tobacco users every day
  • Causes cancer, heart disease, stroke, pulmonary disease, adverse pregnancy out-comes, and shortens life expectancy 14 years
  • Adds $157 billion in costs per year
  • One-third of all tobacco users in U.S. will die prematurely
environmental tobacco smoke second hand smoke
Environmental Tobacco Smoke(Second-hand Smoke)
  • Causes all the diseases that primary smoking causes.
  • Responsible for approximately 40,000 US deaths annually (most from CAD).
  • Leads to 1 million ER visits/yr for asthma.

Health Benefits of Quitting

  • Cancers:

Lung - after 10 years, former smokers have 70% lower risk compared to smokers

Oral & Esophageal - 50% risk after 5 years

  • Cardiovascular disease:
    • CHD - 50% reduction in 12 months
    • Stroke - in 10 years risk is that of nonsmoker
    • PVD - 50% reduction in risk for former
    • smokers
clinical preventive services priorities
Clinical Preventive Services Priorities
  • In spite of best intentions, adult patients have an average of 12 risk factors requiring 24 preventive services.
  • Resources are limited, and knowledge that an intervention is effective is not sufficient to set priorities.
  • Therefore, interventions were assessed on two criteria.
clinically preventable burden cpb cost effectiveness ce
Clinically Preventable Burden (CPB) & Cost Effectiveness (CE)
  • CPB is the product of the burden of disease targeted by the service and its effectiveness and is represented as Quality Adjusted Life Years (QALY)
    • Proportion of disease and injury prevented if delivered to 100% of the target population
  • CE=costs of prevention - costs averted divided by the QALY’s saved expressed in 1995 dollars
summary
Summary
  • Screening and brief counseling for behavior change regarding tobacco use, problem drinking, and physical activity are delivered to less than 50% of the eligible US population.
  • Tobacco cessation services are highly cost-effective and can result in a significant reduction in disease burden.
  • Regular counseling is expected to improve patient health substantially.
slide18

Tobacco use presents a rare confluence of circumstances

  • A highly significant health threat
  • A disinclination among clinicians to intervene consistently
  • The presence of effective interventions
tobacco dependence as a chronic disease
Tobacco Dependence as a Chronic Disease
  • Tobacco dependence demonstrates features of a chronic disease:
    • Long-term disorder
    • Periods of relapse and remission
    • Requires ongoing rather than acute care
opportunity for intervention
Opportunity for Intervention
  • 70% of smokers have made at least one unsuccessful quit attempt.
  • 46% of smokers try to quit each year.
  • More than 70% of smokers visit a health care setting each year.
  • Effective treatments exist which produce long-term or permanent abstinence.

recommendations24
RECOMMENDATIONS

It is essential that clinicians and health care delivery systems (including administrators, insurers, and purchasers) institutionalize the consistent identification, documentation, and treatment of every tobacco user seen in a health care setting.

recommendations25
RECOMMENDATIONS

Brief tobacco dependence treatment is effective, and every patient who uses tobacco should be offered at least brief treatment.

conclusion
CONCLUSION

There is a strong dose-response relation between the intensity of tobacco dependence counseling and its effectiveness. Treatments involving person-to-person contact (via individual, group, or proactive telephone counseling) are consistently effective, and their effectiveness increases with treatment intensity (e.g., minutes of contact).

RECOMMENDATION

Numerous effective pharmacotherapies for smoking cessation now exist. Except in the presence of contraindications, these should be used with all patients attempting to quit smoking.

  • Six first-line pharmacotherapies reliably increase long-term smoking abstinence rates:

• Bupropion SR • Nicotine Nasal Spray

• Nicotine Gum • Nicotine Patch

• Nicotine Inhaler • Nicotine Lozenge

pharmacotherapeutic interventions
Pharmacotherapeutic Interventions
  • All patients attempting to quit smoking should be encouraged to use pharmacotherapy except under special circumstances such as:
    • Medical contraindications
    • Smoking fewer than 10 cigarettes/day
    • Pregnant/breastfeeding women
    • Adolescents
effects of nicotine
Effects of Nicotine
  • Release of dopamine & norepinephrine
  • Boost of energy and euphoria
  • Improved concentration, hand-eye coord.
  • Anorexia
  • Regular use creates physiologic dependence withdrawal, and cravings
slide35

Nicotine Addiction

  • Per milligram dose, nicotine is the most addictive substance known to man.
  • Nicotine acts in the locus ceruleus which controls arousal, concentration, stress reduction, and appetite.
  • Nicotine is a stimulant in the reward pathway causing dopamine release creating dependency.
assessing nicotine addiction
Assessing nicotine addiction:
  • How soon after you wake up do you smoke your first cigarette?
  • How many cigarettes do you smoke in a day?

Extended Use of Pharmacotherapy

  • First-line tobacco dependence medications may be considered for extended use, especially in patients with persistent withdrawal symptoms.
  • Evidence demonstrates that a minority of patients continue ad libitum NRT agents.
  • Does not present known health risks.
  • US FDA has approved bupropion SR for a long-term maintenance indication.
systems interventions
Systems Interventions
  • Health care administrators, insurers, and purchasers should implement systems interventions to promote the consistent identification and treatment of tobacco users:
    • Implement a tobacco-user identification system in every clinic
    • Provide education, resources, and feedback to promote provider intervention
slide63

Systems Interventions (con’t)

  • Dedicate staff to provide tobacco dependence treatments
  • Promote hospital policies that provide inpatient services
  • Include tobacco dependence treatments as a paid or covered service
  • Reimburse clinicians for providing treatment
two questions three minutes very brief counseling
Two Questions, Three MinutesVery Brief Counseling
  • Do you smoke?
  • Do you want to quit?
    • If yes-
      • provide advice
      • set quit date
      • prescribe meds
      • set follow-up
    • If no-
      • provide advice provide advice and move on
remember to
Remember to …

Ask about other forms of tobacco use:

  • Cigars
  • Pipes
  • Smokeless forms (chew and snuff)
slide68

The “5 R’s” to Enhance Motivation for Patients Unwilling To Quit

  • RELEVANCE: Tailor advice and discussion to each patient.
  • RISKS: Discuss risks of continued smoking.
  • REWARDS: Discuss benefits of quitting.
  • ROADBLOCKS: Identify barriers to quitting.
  • REPETITION: Reinforce the motivational message at every visit.
the 5 a s for patients willing to quit
The “5 A’s” For Patients Willing to Quit
  • ASKabout tobacco use
  • ADVISEto quit
  • ASSESS willingness to make a quit attempt
    • willingness to go for intensive treatment
    • gather data regarding their habit
  • ASSISTin quit attempt
  • ARRANGE for follow-up
slide70

Predictive Factors For Cessation

  • Validated predictors of cessation (Farkas, 1996; Dale, 2001)
      • smoking <15 cigs/day and after 30 minutes of waking
      • not smoking daily
      • quit for 6 or more days in 12 months
      • quit for >1 year anytime
elements of a counseling intervention
Elements of a Counseling Intervention
  • Quit Date. Set a stop date, preferably within two weeks. Starting on the quit date, total abstinence is essential.
  • Past quit experience. Identify what helped and what hurt in previous quit attempts.
  • Anticipate triggers or challenges in upcoming attempt. Discuss challenges/triggers and how patient will successfully overcome them.
  • Alcohol. Since alcohol can cause relapse, the patient should consider limiting/abstaining from alcohol while quitting.
  • Other smokers in the household. Quitting is more difficult when there is another smoker in the household. Patients should encourage housemates to quit with them or not smoke in their presence.
slide72

Weight Gain

  • Clinicians should openly address post-cessation weight gain concerns:
    • Acknowledge weight gain is likely but typically limited.
    • Encourage concentration on smoking cessation now, weight control later.
    • Recommend healthy diet and physical activity.
    • Consider pharmacotherapy, particularly bupropion SR and nicotine gum, shown to delay (but not prevent) weight gain.
who is likely to gain the most weight
Who is likely to gain the most weight?
  • “Heavier” smokers

(number of cigarettes)

  • Age <55
  • Underweight women
  • Women who report little physical activity
  • African-Americans
slide75

Preventing Relapse

  • Relapse prevention interventions should be provided with every smoker who has recently quit.
  • Crucial to address relapse the first 3 months after quitting
  • Strategies to use with recent quitters:
    • Encourage continued abstinence.
    • Invite discussion of benefits, success milestones, problems encountered or anticipated.
    • Use or refer to an intensive intervention as appropriate.
in summary
In Summary
  • Brief tobacco dependence treatment is effective and every patient who uses tobacco should be identified, urged to quit, and offered at least one of these treatments:
    • Patients willing to quit should be provided treatments identified as effective.
    • Patients unwilling to quit should be provided an intervention to increase their motivation to quit.
