An important factor in treatment is focusing on active
reduction of risk factors, especially smoking. The 5 As can help
begin the process. The 5 As are: Ask, Advise, Assess, Assist and
Arrange.
Ask patients if they smoke, or have ever smoked. If
the response is “yes,” advise them to quit. Clinical
studies on smoking cessation show that patients often report that
their health care provider knew they smoked, but didn’t say
anything about it. In my practice I always tried to remember to tell
my patients to stop smoking, but some of them have told me I didn't
do enough. Now, every time I see them, I remind them that they have
to quit smoking. More important, you have to assure patients that
they are not going to be alone. You are going to work on this together.
Assess the patient's willingness to make a quit attempt.
Assist them in the quit attempt, and then Arrange for a follow-up.
These 5 As are essential for understanding the principles of smoking
cessation. When you ask and you know they have the disease and then
you advise they have to stop smoking, you try to identify and assess
the willingness of the patient to quit. Then you’re going to
provide support, assisting the patient to quit as well and arranging
follow-up. This is not something the patients are going to do alone,
this is what the patients are going to do working with you. You’re
going to do it together, understanding the need to remove this important
risk factor of COPD.
You Ask, you Advise, but how can you help the patient
stay motivated to quit smoking? The tobacco prevention and dependency
guidelines published by the CDC (see Resources) and the National
Institute of Health have established what is called the 5 Rs, to
increase an individual’s motivation to cease smoking. They
are Relevance, Risks, Rewards, Roadblocks and Repetition. We will
go over these because they are going to be essential when you establish
your patient's plan for smoking cessation.
The first R is Relevance. Encourage patients
to identify why quitting is relevant. It’s relevant for their
condition. It is relevant for the people around them.
Risks. Ask the patient to identify potential
negative consequences of tobacco use like being short of breath,
having heart disease, developing cancer. Point out it’s a bad
role model for young people. Today we also recognize the effects
of secondhand smoke on people around smokers. We know that children
of parents who are smokers are more likely to develop chronic airway
disease, more likely to develop asthma, more likely to have more
bronchitis when they are in their 20s and it carries over to their
40s and 50s.
Rewards. Ask the patient to identify potential
benefits of stopping tobacco use. They are going to cough less, improve
their exercise capacity, live longer, and they are going to save
money. It’s very expensive to smoke today.
Roadblocks. Sit with your patients and identify
the potential barriers to smoking cessation, impediments to quitting.
It’s not going to be an easy road. They are going to have to
work hard, but in the end it is going to be very fruitful for them.
Repetition is the fifth R. Repeat this message at each
interaction. Every time you see your patients you have to do the
5 As and the 5 Rs. You need to ask “do you continue to smoke?” If
the answer is yes, you need to give them reasons why they have to
be motivated to stop smoking.
I tell my patients that smoking cessation is a combination
of behavior modification and pharmacotherapy. Using pharmacotherapy
alone is not going to do the job. Behavior modification or support
groups alone are not going to work. You have to marry both of these
interventions. Smoking is a habit that is part of the patient's way
of life. Just like the way they walk, the way they talk, the way
they comb their hair, smoking is a part of them. So, they need to
identify where they smoke and what they do when they smoke. Then
you have to start behavioral interventions. There is a lot of support
for people trying to quit smoking. There is support on-line, there
are 24-hour support telephone numbers, there are support groups and
other support programs.
Clinical studies for pharmacological interventions
have been very successful in showing that smoking cessation can be
achieved. There is considerable evidence to support the view that
cigarette smoking is primarily maintained by an addiction to nicotine.
Nicotine creates a dependency and as a consequence of that, we can
intervene in different ways.
There are five forms of nicotine replacement therapy:
the nicotine gum, the patch, the nasal spray, the inhaler, the lozenge.
My recommendation, based on what I prescribe for my patients, is
to give either a gum or a nasal spray to use when patients feel the
urge to smoke. It provides the acute relief and acute satisfaction
experienced when they smoke.
Buproprion, an antidepressive, has demonstrated efficacy
in clinical studies. More recently the Cochrane study looked at interventions
with a new drug, varenicline, that have demonstrated that it is more
effective than buproprion in smoking cessation.
Varenicline is a non-nicotinic agent. The mechanism
of action is a partial agonist of the nicotine receptor in the brain.
This is the area in the brain where patients receive satisfaction
and that is where nicotine attaches when the patient smokes. This
compound is an agonist that blocks that receptor so the patient has
already experienced the satisfaction. There are two placebo controlled
trials that demonstrate in a continuous abstinence the superiority
of varenicline versus buproprion when it is given, and the studies
show different designs. In one clinical study the patients received
the medication for up to twelve weeks. In the other clinical study
the patients received another course of therapy three months after
they had stopped smoking. The second study concluded that varenicline
is more efficacious against placebo, nicotine replacement, and buproprion.
More important, it proved that after your patient has stopped smoking
if you repeat the course of therapy three months later, at the end
of the year the patient will be more likely to have stopped smoking.
In any discussion of pharmacotherapy it is essential
to first review treatment goals. The GOLD guidelines as well as those
of the ACP, the American College of Family Physicians and many other
primary care and specialties organizations, have established goals
for therapy for COPD. We want to prevent disease progression. We
want to relieve the symptoms, but at the same time we want to improve
the health status. We want to increase exercise tolerance. We want
to prevent and treat exacerbations and treat complications. We want
to prevent or minimize side effects from treatment.
At the end of the day what we want to do is change
the course of the disease. We would like to prolong survival with
a better quality of life. We want to decrease mortality. To achieve
all this, we also want to minimize any treatment related adverse
events. The goals GOLD has developed are very different from what
we had ten years ago. In the past, our goals were to make the patient
feel better, to breathe better for four to six hours. We didn’t
understand the implications of having the long-acting bronchodilators
we have now. We never thought that we could change the goals of the
treatment of this disease. Now we have broadened the goals and we
can impact the course of COPD. Achieving these goals is possible
today because of the tools, pharmacotherapies and interventions that
we now have available to us.
