Long Term Care Patients
Pamela L. Stamm, PharmD, CDE, BCPSAssociate Professor of Pharmacy Practice
Auburn UniversityJune 25, 2012
Where do you provide care?
a) Community pharmacy
b) Long term care pharmacy
c) Hospital
d) Academia
e) I am retired!!!!!!!
Objectives
1. Differentiate COPD from other respiratory diseases2. Outline an algorithm for chronic COPD treatment3. Compare and contrast tiotropium and ipratropium’s
safety and efficacy in COPD4. Describe the role of inhaled corticosteroids in COPD5. Assist patients in avoiding inhaler misuse6. Minimize the risk of adverse effects of COPD therapy7. Identify medications which could interfere with
respiration in the patient with COPD
OVERVIEW OF COPD
Basic Stats
• 24+ million in the US have COPD• 50% are undiagnosed
• 13% of all nursing home residents have COPD
• 40% chance will enter the nursing home
• 4th leading cause of death• >100,000 die annually from COPD
Which are COPD Risk Factors?
a) Smoking
b) Air pollution
c) Gender
d) History of childhood respiratory infections
e) Occupational dusts and chemicals
Which of the following persons have COPD?
Recognizing COPD / Hallmark Symptoms
Hallmark COPD Symptoms
• Dyspnea (progressive, persistent, worse w/ exercise)
• Cough (dry, productive, or intermittent)• Sputum production
Other patient characteristics:• Exposure to risk factors• Family History
Diagnosis
• Via spirometry: • Postbronchodilator only• Reduced FEV1:FVC ratio < .7
• Reversibility
OVERVIEW OF COPDTREATMENT GUIDELINES
Four Components of COPD Management
Four Components of COPD Management
1. Assess and monitor disease
2. Reduce risk factors
3. Manage stable COPD
4. Manage exacerbations
1. Assess and monitor disease
2. Reduce risk factors
3. Manage stable COPD
4. Manage exacerbations
How to reduce disease progression?
a) Smoking cessationb) Add albuterolc) Add antimuscarinicd) Pulmonary rehabilition
Data suggests Long Acting Bronchodilators and Inhaled Corticosteroids may reduce progression
Benefit of Cessation
• ASK Identify tobacco users at all visits.
• ADVISE Strongly urge users to quit.
• ASSESS Determine willingness to quit
• ASSIST Aid quitting
• ARRANGE Schedule follow-up contact.
Strategies to aid cessation
Cessation Therapy
• Comparing monotherapies
• Combined therapy vs monotherapy
• Extended therapy
Monotherapy vs. Placebo

Which statement is true?
a) Pharmacotherapy doesn’t increase cessationb) Most data supports extended NRT treatment c) Cessation rates drop once treatment in
stoppedd) 6 month data suggests combining patch and
lozengee) Both C and D are true
Importance of Counseling in Cessation
Counseling by health professionals significantly increases quit rates
Brief (3-minute) counseling urging cessation results in 5-10% cessation
Pharmacotherapy is recommended when counseling is insufficient

GOLD Guidelines . 2011. http://www.goldcopd.org/
Approach to selecting therapy
• Step 1: Assess impact of symptoms
• Step 2: Assess risk of exacerbations
• Step 3: Combine results of steps 1 and 2
• Step 4: Select drug therapy
COPD Assessment Test (CAT): http://catestonline.org• 8-item measure of health status impairment in COPD
0-10 Low 10-20 Medium21-30 High31-40 Very High
Breathlessness Measurement using the Modified British Medical Research Council (mMRC) Questionnaire:
• Relates well to other measures of health status and predicts future mortality risk.
Step 1: Assess Symptoms
I never cough 0-5 I cough all the timeI have no phlegm (mucous) in my chest at all
0-5 My chest is completely full of phlegm (mucous)
My chest does not feel tight at all
0-5 My chest feels very tight
When I walk up a hill or one flight of stairs I am not breathless
0-5 When I walk up a hill or one flight of stairs I am very breathless
I am not limited doing any activities at home
0-5 I am very limited doing activities at home
I am confident leaving my home despite my lung condition
0-5 I am not at all confident leaving my home because of my lung condition
I sleep soundly 0-5 I don't sleep soundly because of my lung condition
I have lots of energy 0-5 I have no energy at all
Modified MRC (mMRC)Questionnaire
0 □ I only get breathless with strenuous exercise1 □ I get short of breath when hurrying on the
level or walking up a slight hill
2 □ I walk slower than people of the same age on the level because of breathlessness, or I have to stop for breath when walking on my own pace on the level
3 □ I stop for breath after walking 100 meters or after a few minutes on the level
4 □ I am too breathless to leave the house or I am breathless when dressing or undressing

Importance of Education
For Pressurized MDIs, Plaza and colleagues • No education group 72% made errors• Education group 48% made errors
Verbal education is better than reading a patient package insert (PI)• Reading PI 89% made errors• Verbal instruction 48% made errors
Respiration 1998;65:195-8. Thorax 2000; 55 (Suppl 3):A61.
Importance of Education
• Knowledge of technique does not guarantee ability (make them show you)
• Ability varies by day
• Pediatrician study showed 26% (10 of 38 ) demonstrated all steps correctly
Ann Allergy Immunol. 1996; 76 (2): 145-148(4)
How Do Pharmacists Fare?
CHEST 1993 ; 104( 6): 1737-1742
Why is Good Technique So Difficult?
• Frequency of errors increases with age and COPD severity
• Patients don’t think it through especially when feeling symptoms
• Cannot inhale forcefully enough due to disease
• Multiple devices with different techniques• It works for them…or so they think
Select the appropriate inhaler for the following steps
pMDI DPI Both
• Shake the inhaler• Prime the inhaler• Remove the cap• Inhale fast and deeply• Hold breath up to 10 seconds (4-10)• Exhale through mouth• Rinse and spit• Clean once weekly by running under water
pMDI DPI
• Shake the inhaler (5 sec)• Remove the cap / inspect
opening• Prime the inhaler (see PI)• Exhale slowly• Open/ closed mouth technique• Inhale slowly and deeply• Hold breath up to 10 seconds
(4-10)• Exhale through mouth• Wait 1 minute between doses• Rinse and spit• Clean once weekly by running
opening under water
• Remove cap (if applicable)
• Activate dose & hold correctly• Exhale slowly• Closed mouth technique only• Inhale fast and deep• Hold breath up to 10 seconds
(4-10)• Exhale through mouth• Wait 1 minute between doses• Rinse and spit• Wipe mouthpiece weekly with
dry tissue
Identifying the Crucial Errors
• Failure to remove cap / cover
• Failure to load dose / prime correctly
• Inhaler held incorrectly (upside down, not level)
• Coordination of inhalation and actuation
• Open mouth technique w/ chamber or DPI
• Inhalation at wrong speed
• Inhalation through nose
What’s wrong with this picture?
Lynn Age 46
• Watch video• Watch for symptoms of COPD• Watch inhaler technique. How does she do?
http://www.youtube.com/watch?v=bt6EC-57sbw
Selecting the Best Inhaler
• Patient dependent, patient preference
• Attempt to select similar inhalers (all DPIs or all pMDIs)
• Provide reminders on device
• Observe patient’s technique

JA, a 58 yo male, c/o increasing SOB…
Recently saw PCP who switched his Oxycodone to an equivalent dose of MS Contin. PMH: COPD, DM, HTN, MI, and Chronic Pain.
Current medications: • glipizide 10mg BID • morphine sulfate SR 30mg Q8 hr• metformin 1000mg BID • morphine sulfate IR 15mg • ramipril 10 mg Qday PRN breakthrough pain• HCTZ 12.5 mg Qday • ASA 81 mg Qday• atenolol 50mg Qday
Which medication(s) could be contributing?
a) Metformin
b) Morphine sulfate
c) Atenolol
d) ASA
Medications that Impair Breathing
• Opioid Agonists• Reduce respiratory drive when in excess• Can reduce dyspnea wo/ significant respiratory
depression • Avoid excessive doses• Monitor for signs of overdose
Medications that Impair Breathing
Beta Antagonists• B1 and B2 receptors in lungs• B2 receptors comprise majority of receptors and
are the only receptors on airway and vascular smooth muscle
• B1 receptors comprise 10-30% at other lung locations
• Theory: antagonism can reduce lung function• Theory: nonselective > selective
Beta Antagonists the Evidence
• FEV1 remains unchanged in patients on BB• Bronchodilator use no different from controls• No difference in ED visits or hospitalizations• Morbidity & mortality benefits in pts w/ cardiac
disease & possibly in those wo/• Should be maintained during acute exacerbations• Reduce mortality in patients w/ concomitant

Summary
• Smoking Cessation is key!
• LABA are ok monotherapy in COPD
• Tiotropium appears safe, ipratropium unclear
• Pt specific inhaler selection and repeated education is essential
• Do not avoid Beta Antagonists or opioids just because your patient has COPD
