Epidemiology: Smoking and Mental Illness
People with serious mental illness die, on average, 25 years younger than the general population
Poorer health careA 10 year study of elevated coronary heart disease risk in schizophrenia: tobacco use identified as the major causal factor after controlling for BMI/weight
59% of public mental health facilities permit smoking

Epidemiology: Smoking and Mental Illness
Overall smoking in the United States has decreased but the proportion of smokers with psychiatric disorders has increased
75% of those with either addictions or mental illness smoke compared to 21% in the general population
Nearly ½ the cigarettes smoked in the U.S. are smoked by those with psychiatric disorders

Epidemiology: Smoking and Mental Illness
Smoking Prevalence among People with Mental Illnesses
Major Depression 50-60%Anxiety Disorder 45-60%Bipolar Disorder 55-70%Schizophrenia* 65-85%ADHD 40%
*20% of those with schizophrenia started smoking at college age and many began smoking in mental health settings, receiving cigarettes for “good behavior”

Social factors to consider
Limited educationPoverty
Steinberg, Williams, & Ziedonis (2004) found that smokers with schizophrenia spent at least 1/4 of their monthly disability on cigarettes
UnemploymentAbundance of smoking peersUnderground market for cigarettes
LoosiesIndian Reservations

Clinician factors to consider
Psychiatric clinicians have responded slower than other health professionalsCigarettes as behavioral reinforcementBelief that smoking reduction/cessation is not a realistic goalPatients “only pleasure” & “least of their worries”Contributes to “normalizing”

Common Patient Perspectives
“Smoking helps me calm down.”“Smoking helps me concentrate.”“I smoke because I’m bored.”“Smoking is one of the few things I do that I enjoy.”“Sticking to a cessation plan is too hard.”

Yet many smokers with psychiatric illnesses do want to quit
People with mental illnesses want to stop smoking and often seek information about how to stop smoking
They (and we) often lack confidence, however, in their ability to be successful
They often lack social support, which predicts better cessation rates

The same interventions that help the general population are likely to help
our clients if provided at greater intensity and for longer periods of
time

The nature of nicotine addiction
Of all the substances of abuse, nicotine has the highest probability of causing dependency when one has tried it at least once; nicotine may be the most addicting substance known.

Nicotine Pharmacodynamics (Taylor, 2006)
Nicotine binds to receptors in the brain and other
sites in the body
Other:Neuromuscular junctionSensory receptorsOther organs
Central nervous system
Exocrine glands
Adrenal medulla
Peripheral nervous system
Gastrointestinal system
Cardiovascular system
Nicotine has predominantly stimulant effects.

Nicotine Pharmacodynamics: Withdrawal Effects
Although symptoms may peak 24–48 hr after quitting and subside within 2–4
weeks, there is considerable individual
variation in withdrawal symptoms so it is very important
to listen to what your patients tell
you!

Potential neurobiological benefits of nicotine for those with psychiatric disorders
Effects on neurotransmitters postulated to: Reduce negative (deficit) symptoms of the schizophrenic syndromeImprove working memory, attention, & motor speedNormalize impaired sensory gating functionReduce antipsychotic drug side effects, e.g. akathisia

Nicotine Pharmacology & Addiction
Nicotine dependence is a form of chronic brain disease.
Tobacco use is a complex disorder involving the interplay of the following:
Pharmacology of nicotine (pharmacokinetics and pharmacodynamics)
Environmental/social factors
Physiologic factors
Treatment of tobacco use and dependence requires a multifaceted treatment approach

PHS Guideline for Treating Tobacco Use & Dependence
Highly significant health threat
Disinclination among clinicians to intervene consistently
Presence of effective interventions

Types of Interventions
Lower intensity3-10 minutesTargets smokers who are willing, unwilling, and those who recently quit
Higher intensitySession length > 10 minutes4 or more sessionsTend to be coordinated by tobacco dependence specialistsMultiple clinician types

Recommended Clinical Approaches4
The “5 A’s”
for patients willing to make a quit attempt
4
The “5 R’s”
for patients unwilling to make a quit attempt at this time
4
Relapse prevention for patients who have recently quit
4
Intensive interventions should be provided when possible (there is a strong dose-response; more intensity = better quit rates)
4
Health care administrators, insurers, and purchasers should institutionalize guideline findings

Smoking stimulates α4β2 receptorsReceptors become desensitized within minutes (~one cigarette)Receptors re-sensitize after 45 minutes

A Patient-Centered Approach to NRT Dosing
Estimate amount of nicotine patient is getting from smokingGenerally 1-1.5 mg. of nicotine/cigarette
Cover with comparable NRT (often helpful to use a continuous + intermittent form of NRT) mindful that NRT is more slowly absorbed than nicotine from cigarettes; higher peak levels of nicotine result in higher subjective effects of nicotine; often need higher doses of NRT to achieve same effects
Review signs/symptoms of potential side effects including information that combination NRT is not FDA approved/discuss risks & benefits
![Page 35: Practical Skills for Working with your Patients who SmokePractical Skills for Working with your Patients who Smoke Daryl Sharp, PhD, APRN, BC, FNAP ...

35
A Patient-Centered Approach to NRT Dosing
Teach patient signs/symptoms of nicotine withdrawal & nicotine toxicity
On a scale of 0-3 (0=none; 1=mild; 2= moderate; 3= severe)Signs of withdrawal:
AnxietyIrritabilityDifficulty concentratingCravings for cigarettes

Additional NRT Guidelines
Combining the nicotine patch & ad libitumNRT (nicotine gum/nicotine nasal spray) is more efficacious than a single form of NRT
FDA has not approved combination NRT strategy
Certain groups of smokers may benefit from extended use of NRT
Continued use of medication is clearly preferable to a return tosmoking with respect to health consequences
Risks/benefits analysis and patient preferences should inform pharmacotherapy choices

Process of counseling
Studies have shown that the way in which you counsel your clients makes a difference in how successful they are in changing health behaviors
The PROCESS of counseling is as important as the CONTENT of the intervention
![Page 56: Practical Skills for Working with your Patients who SmokePractical Skills for Working with your Patients who Smoke Daryl Sharp, PhD, APRN, BC, FNAP ...

Mobilizing Motivation: Autonomy Support/Motivational Interviewing

AutonomyCompetenceRelatedness
Counselor-client relationship is a partnership (not expert/recipient)
Elicit and acknowledge the client’s perspectiveListen well and reflect

57
Mobilizing Motivation: Autonomy Support/Motivational Interviewing

Ask permissionCheck in with clients about how they are hearing the informationProvide rationale for suggestions you offer
Avoid willfulness and maintain neutrality
Support client initiatives for change

Summary
Few mental health professionals effectively address tobacco dependence currently
Interventions delivered in primary care or other public health settings usually lack intensity needed for SMI population
Effective treatment:Promoting a tobacco free culture in treatment settings
No smoking policiesStaff consistently addressing tobacco use and supporting clients’ efforts to quit
Providing a specialized tobacco dependence serviceEasy access to medications Unlimited treatment sessions

Nursing’s responsibility & challengeIt is unethical to provide health care and
at the same time remain silent (or inactive) about a major health risk
The time to act is NOW!
Failure to act = HARM
Action = HOPE
