– an opportunity for
Pharmacists
Chad Worz, Pharm.D.
President, Medication Managers, LLC
Adjunct Professor, University of Cincinnati, College of Pharmacy
Objectives and Agenda
S Recognize the burden of disease in older adults
S Acknowledge Burden on our Health Care System
S Describe the pharmacology of treatments and their
impact on the disease process
S Demonstrate the varied administration methods for
treatments and the importance in post acute care
S Recognize the new Treatment Guidelines for COPD
S Define the role of the pharmacist
COPD Defined.
S Chronic Obstructive Pulmonary Disease
(COPD) is a common, preventable and
treatable disease that is characterized by
persistent respiratory symptoms and airflow
limitation that is due to airway and/or alveolar
abnormalities usually caused by significant
exposure to noxious particles or gases.
COPD Defined.
S The most common respiratory symptoms include
dyspnea, cough and/or sputum production. These
symptoms may be under-reported by patients.
S The main risk factor for COPD is tobacco smoking
but other environmental exposures such as biomass
fuel exposure and air pollution may contribute.
Besides exposures, host factors predispose
individuals to develop COPD. These include genetic
abnormalities, abnormal lung development and
accelerated aging.
COPD Has Been Shown to Be a
Common and Costly Condition
COPD is the 3rd leading cause of death in the United
States1,2
COPD is the 2nd leading cause of disability3
By 2010, there were 14.8 million diagnosed COPD
patients in the US4
COPD accounts for an estimated $29.5 billion in
direct healthcare expenses5

COPD in Long Term Care
One of every six admissions to nursing homes was for patients with a history of emphysema or COPD1
In the last 12 months of COPD patients’ lives, one recent study reported there was a 40% likelihood of being admitted to a LTC facility2
Approximately 22% of the respiratory-related healthcare costs are nursing home costs; a greater amount was spent on hospitalizations (approximately 50%)

COPD in Long Term Care
The majority of persons with COPD have cardiovascular
disease including coronary artery disease, heart failure, and
hypertension.
Stroke occurs in a significant portion of persons with COPD.
About 25% of persons with COPD have concurrent asthma.
Age-related and steroid-induced osteoporosis occur frequently
in persons with the disease, and COPD is a risk factor for
nursing home–associated pneumonia.
A significant number of persons with COPD have obstructive
sleep apnea.

COPD in Long Term Care
Depression and anxiety are also common in COPD; one study found that 40% of persons with COPD have depressive symptoms.
Diabetes mellitus occurs in about 25% of persons with COPD.
Malnutrition is a significant issue in some individuals with COPD.
Substantial chronic airway obstruction leads to greater energy requirements due to the increased work of breathing, as well as inactivity from deconditioning

Maintenance Therapy for Long-term
COPD Care–Considerations
Focus of COPD care is shifting from acute treatment to long-term
maintenance1-3
Many patients did not receive any maintenance COPD therapy4
GOLD can be used to inform the prescribing of maintenance therapy3,5
When selecting an inhaled COPD therapy, drug delivery and training
should be considered5

Maintenance Therapy for Long-term
COPD Care–Considerations
In the hospital prior to discharge, patients should start long-acting
bronchodilators, either beta2-agonists and/or anticholinergics with or
without inhaled corticosteroids5
Add 1 or more classes of long-acting bronchodilators when needed5

Short-Acting 2-Adrenergic Agonists
S If response to initial anticholinergic therapy suboptimal, add 2-adrenergic agonist1,2
S Combination MDI (ipratropium and albuterol)1,3,4: S Greater efficacy, equivalent safety
S Lower rate of exacerbations
S Lower total treatment costs
S Improved cost-effectiveness
MDI, metered-dose inhaler
PDE4 Inhibitors
S Roflumilast therapy has a limited role in patients with severe COPD, and no role in patients with mild to moderate COPD.
S It will not decrease the number of hospitalizations.
S It will slightly lower the number of exacerbations requiring oral corticosteroid treatment, but only in select patients (i.e., those with a combination of severe COPD, current bronchitic symptoms, and a previous exacerbation).
Am Fam Physician. 2014 Feb 15;89(4):300-301
Theophylline1
S If response to initial anticholinergic/2-agonist therapy suboptimal, consider adding theophylline
S Long-acting formulations generally preferred
S Modest bronchodilation, mild anti-inflammatory effects
S Useful for noncompliant patients and those who have trouble with inhalation aerosols and those preferring oral drugs
S Titrate dose to serum level up to a maximum of 12 g/mL
S Some patients experience side effects at lower serum levels
1. NCAP. J Respir Dis. 2000;21(suppl):S5-S21.
Anti-Inflammatory Agents
S If bronchodilator response is suboptimal, consider adding an anti-inflammatory drug1 S Corticosteroids (oral/inhaled)
S Useful in few patients1 S Consider 2-week trial of oral corticosteroid (40 mg prednisone QD)
S Discontinue if no response
S If patient responds, taper to minimal effective dose level and switch to inhaled corticosteroid

Administration
S MDI (Metered Dose Inhaler) vs. HHN (Hand Held Nebulizer) S A HHN is not superior to an MDI S The problem is technique (consider a spacer)
S With optimal technique a MDI delivers close to 12% of the drug to the lung.
S In general, the HHN dose needs to be 6 to 10 times higher than the MDI to deliver the same degree of bronchodilation.
S Consider nursing administration time
S Consider the patient
