Impact of Smoking on the Lungs
Even low levels of tobacco smoke significantly effect smoking-responsive genes in the small airway epithelium

Smoking, COPD & GenderLung function reduction and COPD severity
were the same for male and female subjects, but women were:• younger • started smoking at a later age• had smoked fewer pack-years Differences were more pronounced in the early-
onset and low exposure COPD subgroupsSorheim, et al. Thorax. 2010

So Why Do People Use Tobacco?
![Page 7: Addressing Persistent Tobacco Use in Persons with Cardiopulmonary Disease Audrey Darville, PhD, APRN, CTTS Certified Tobacco Treatment Specialist UK HealthCare/UK](https://reader035.vdocuments.us/reader035/viewer/2022062516/56649e2a5503460f94b17fdc/html5/thumbnails/7.jpg)
The Tobacco Industry wants us to believe tobacco use is a personal choice
![Page 8: Addressing Persistent Tobacco Use in Persons with Cardiopulmonary Disease Audrey Darville, PhD, APRN, CTTS Certified Tobacco Treatment Specialist UK HealthCare/UK](https://reader035.vdocuments.us/reader035/viewer/2022062516/56649e2a5503460f94b17fdc/html5/thumbnails/8.jpg)
Case Study
Mr. J., 46, has severe heart disease from multiple heart attacks and continues to smoke 2 PPD. When asked about his tobacco use, he replied it had nothing to do with his heart attacks, so there was no point in talking about it as he just gets “ugly” when he doesn’t smoke.
![Page 9: Addressing Persistent Tobacco Use in Persons with Cardiopulmonary Disease Audrey Darville, PhD, APRN, CTTS Certified Tobacco Treatment Specialist UK HealthCare/UK](https://reader035.vdocuments.us/reader035/viewer/2022062516/56649e2a5503460f94b17fdc/html5/thumbnails/9.jpg)
What was the origin of his beliefs?
• After his heart attacks his doctor told him he needed to cut out eating salt and fat and lose weight. He said “nothing about smoking” (that the patient heard)• Many family members smoke and their hearts
were OK• Stress would kill him faster than smoking and his
life was pretty stressful• “If someone tells me to do something, I’m going to
do the opposite. That’s just how I am.”
![Page 10: Addressing Persistent Tobacco Use in Persons with Cardiopulmonary Disease Audrey Darville, PhD, APRN, CTTS Certified Tobacco Treatment Specialist UK HealthCare/UK](https://reader035.vdocuments.us/reader035/viewer/2022062516/56649e2a5503460f94b17fdc/html5/thumbnails/10.jpg)
Is he ready to quit (and does it matter)?•Consider how complex it is to describe
the effects of tobacco on the heart•Consider his experiences with tobacco
and quitting
![Page 11: Addressing Persistent Tobacco Use in Persons with Cardiopulmonary Disease Audrey Darville, PhD, APRN, CTTS Certified Tobacco Treatment Specialist UK HealthCare/UK](https://reader035.vdocuments.us/reader035/viewer/2022062516/56649e2a5503460f94b17fdc/html5/thumbnails/11.jpg)
Is it the Habit or the Drug?
• “Choice” is the Tobacco Industry message…• Do we consider tobacco use (nicotine
addiction) a chronic disease?• Addiction is not logical: We generally
won’t convince someone that nicotine patches are cheaper than cigarettes• Are we dispelling “myths of smoking”
effectively?
![Page 12: Addressing Persistent Tobacco Use in Persons with Cardiopulmonary Disease Audrey Darville, PhD, APRN, CTTS Certified Tobacco Treatment Specialist UK HealthCare/UK](https://reader035.vdocuments.us/reader035/viewer/2022062516/56649e2a5503460f94b17fdc/html5/thumbnails/12.jpg)
Cessation “Myths” to be challenged
• In order to quit you really have to want to quit• Medications are more harmful than smoking• Some people just can’t/won’t quit• Medicine won’t work unless you want to quit• You don’t need to talk about it, you just need to
do it• Don’t try to quit smoking when you’re trying to
get sober or quit drugs, it’s too stressful• Reducing your smoking or switching to
smokeless/e-cigs are better for your health
![Page 13: Addressing Persistent Tobacco Use in Persons with Cardiopulmonary Disease Audrey Darville, PhD, APRN, CTTS Certified Tobacco Treatment Specialist UK HealthCare/UK](https://reader035.vdocuments.us/reader035/viewer/2022062516/56649e2a5503460f94b17fdc/html5/thumbnails/13.jpg)
What’s Motivation Got to Do with It?
•What constitutes “Motivation”?•How is it different than “Readiness”?•What is the clinical evidence for the role of motivation in behavior change?
![Page 14: Addressing Persistent Tobacco Use in Persons with Cardiopulmonary Disease Audrey Darville, PhD, APRN, CTTS Certified Tobacco Treatment Specialist UK HealthCare/UK](https://reader035.vdocuments.us/reader035/viewer/2022062516/56649e2a5503460f94b17fdc/html5/thumbnails/14.jpg)
Motivation
According to Google…• The reason or reasons one has for
acting or behaving in a particular way.• The general desire or willingness of
someone to do something.
![Page 15: Addressing Persistent Tobacco Use in Persons with Cardiopulmonary Disease Audrey Darville, PhD, APRN, CTTS Certified Tobacco Treatment Specialist UK HealthCare/UK](https://reader035.vdocuments.us/reader035/viewer/2022062516/56649e2a5503460f94b17fdc/html5/thumbnails/15.jpg)
Components of Motivation
Importance/Salience“I really have to quit”“Smoking is killing me”
Confidence/Self-efficacy“I’m too stressed to quit right now”“I’ve tried to quit so many times”
![Page 16: Addressing Persistent Tobacco Use in Persons with Cardiopulmonary Disease Audrey Darville, PhD, APRN, CTTS Certified Tobacco Treatment Specialist UK HealthCare/UK](https://reader035.vdocuments.us/reader035/viewer/2022062516/56649e2a5503460f94b17fdc/html5/thumbnails/16.jpg)
Readiness versus Motivation
•Readiness focuses on the barriers•Motivation explores the REASONS behind the barriers
![Page 17: Addressing Persistent Tobacco Use in Persons with Cardiopulmonary Disease Audrey Darville, PhD, APRN, CTTS Certified Tobacco Treatment Specialist UK HealthCare/UK](https://reader035.vdocuments.us/reader035/viewer/2022062516/56649e2a5503460f94b17fdc/html5/thumbnails/17.jpg)
The Science in a nutshell…
•Motivational interviewing may help people quit and is widely used•Most effective when used by trained
professionals• Avoids aggressiveness and confrontation•More is better
Motivational interviewing for smoking cessation (Cochrane Review). 2010
![Page 18: Addressing Persistent Tobacco Use in Persons with Cardiopulmonary Disease Audrey Darville, PhD, APRN, CTTS Certified Tobacco Treatment Specialist UK HealthCare/UK](https://reader035.vdocuments.us/reader035/viewer/2022062516/56649e2a5503460f94b17fdc/html5/thumbnails/18.jpg)
How it WorksA content analysis of a Randomized Control Trial found counseling:• Supports confidence about quitting and reduces perceived
difficulty quitting• Prompts avoidance of access to cigarettes• Improves quitting self-efficacy• Reduces perceived difficulty of quitting over time• Protects against guilt and demoralization following lapses• Supports the importance of receiving social support• Strengthens motivation and confidence• Eases withdrawal distress during cessation efforts
McCarthy, et. al. Addiction. 2010.

Understanding Disparities…• “Nicotine-dependent individuals
with a comorbid psychiatric disorder made up 7.1% of the population yet consumed 34.2% of all cigarettes smoked in the United States”• Persons with mental illness die, on
average, 25 years younger than the general population
Grant, B.F. , et al. Archives of General Psychiatry 2004.

Putting it into PracticeQuit Rulers:

Helpful to Know…• Age of onset of smoking• Nicotine dependence (high if time to first cigarette is
30 minutes or less)• Prior quit attempts/methods used• Exposure to other smokers/secondhand smoke
![Page 22: Addressing Persistent Tobacco Use in Persons with Cardiopulmonary Disease Audrey Darville, PhD, APRN, CTTS Certified Tobacco Treatment Specialist UK HealthCare/UK](https://reader035.vdocuments.us/reader035/viewer/2022062516/56649e2a5503460f94b17fdc/html5/thumbnails/22.jpg)
Components of Effective Counseling
Promoting Importance of Quitting:Develop discrepancies between
current behavior and desired behaviorPromoting Confidence to quit:
Develop a plan and engage useful tools (including medication) to assist in changing behavior
![Page 23: Addressing Persistent Tobacco Use in Persons with Cardiopulmonary Disease Audrey Darville, PhD, APRN, CTTS Certified Tobacco Treatment Specialist UK HealthCare/UK](https://reader035.vdocuments.us/reader035/viewer/2022062516/56649e2a5503460f94b17fdc/html5/thumbnails/23.jpg)
Tailored Approaches Work: Reducing to Quit
• A Cochrane Review (Lindson, Aveyard & Hughes, 2010) found 10 studies that looked at reducing cigarettes prior to quitting compared to making no change in CPD smoked• Found no significant difference between
the 2 strategies in quit rates, concluding either strategy can be recommended for quitters (tailoring)
![Page 24: Addressing Persistent Tobacco Use in Persons with Cardiopulmonary Disease Audrey Darville, PhD, APRN, CTTS Certified Tobacco Treatment Specialist UK HealthCare/UK](https://reader035.vdocuments.us/reader035/viewer/2022062516/56649e2a5503460f94b17fdc/html5/thumbnails/24.jpg)
ROADBLOCK: Switching to Quit (aka Harm Reduction)?
• Strategy that is causing international controversy in tobacco control• Involves promoting the use of alternate
products (smokeless tobacco including snus, electronic cigarettes most commonly)• A significant amount of harm reduction
science receives funding from the tobacco industry
![Page 25: Addressing Persistent Tobacco Use in Persons with Cardiopulmonary Disease Audrey Darville, PhD, APRN, CTTS Certified Tobacco Treatment Specialist UK HealthCare/UK](https://reader035.vdocuments.us/reader035/viewer/2022062516/56649e2a5503460f94b17fdc/html5/thumbnails/25.jpg)
Is Less Harmful=Not Harmful?• Tobacco industry is aggressively marketing
smokeless and novel tobacco products, such as e-cigarettes, as “less harmful” alternatives to smoking traditional cigarettes• Smokeless use has been associated with an
increased risk of fatal MI and Stroke Piano, et al (2010), Yatsuya & Folsom (2010)
![Page 26: Addressing Persistent Tobacco Use in Persons with Cardiopulmonary Disease Audrey Darville, PhD, APRN, CTTS Certified Tobacco Treatment Specialist UK HealthCare/UK](https://reader035.vdocuments.us/reader035/viewer/2022062516/56649e2a5503460f94b17fdc/html5/thumbnails/26.jpg)
E-cig Concerns• FDA regulation is pending: No current
standards exist• Particulates, including tin, have been found in
the inhaled vapor Williams, et al., Plos One, 2013
• Acute pulmonary effects similar to tobacco smoke effects have been seen in electronic cigarette users Vardavas, et al. Chest 2012
• Case report of lipoid pneumonia attributed to e-cig use McCauley, et al, Chest, 2012

E-cig Marketing Forces At WorkNow that big tobacco companies are major players in the e-cig market there has been an explosion in marketing (déjà vu?):
![Page 28: Addressing Persistent Tobacco Use in Persons with Cardiopulmonary Disease Audrey Darville, PhD, APRN, CTTS Certified Tobacco Treatment Specialist UK HealthCare/UK](https://reader035.vdocuments.us/reader035/viewer/2022062516/56649e2a5503460f94b17fdc/html5/thumbnails/28.jpg)
Additional Evidence-Based Techniques• Expressing Empathy: “What do you like
about smoking? How does it help you?”• Rolling with Resistance: “It’s hard to find a
good time to quit. What do you think will help you move forward?”• Supporting self-efficacy: “Tell me how the
medication is doing for you.”
