Case Study 1
• George W., a 75-year-old retired office worker with a 10-year history
of COPD recently has been experiencing more shortness of breath
and difficulty helping his wife around the house. He also has
required frequent SABA refills.
• George smoked a pack of cigarettes a day for 50 years, but quit at
diagnosis of COPD. He has osteoarthritis, particularly in the hands,
and also suffers from type 2 diabetes mellitus (DM). He has had
several transient ischemic strokes over the last few years.
• Medications:
– LABA using a dry powder inhaler as COPD maintenance
therapy, as well as a SABA for rescue therapy and an oral
glucocorticoid for treatment of acute exacerbations
– A sulfonylurea for glucose control
– An antiplatelet agent to reduce the risk of stroke
– A nonsteroidal anti-inflammatory drug for osteoarthritis
15
In elderly patients with cognitive problems and/or physical
disabilities, what would you typically prescribe for maintenance therapy?
1. I don’t prescribe therapy for these patients
2. I prescribe a short‐acting beta2‐agonist (SABA) for rescue therapy as needed rather than a LABA for maintenance 3. I prescribe a LABA using a breath‐activated inhaler (ie, nebulizers
that generate aerosol only on inspiration) for these patients and a SABA for rescue therapy as needed
4. I prescribe a LABA /inhaled corticosteroid (ICS) fixed dose combination
5. I prescribe a LABA using a nebulizer for these patients and a SABA for rescue therapy as needed
14

Case Study 1—Poor Disease Control
Case Study 1—Course of Action
• Signs of possible nonadherence
– Frequent exacerbations
– Patient is going through rescue medication
too quickly
– Forced expiratory volume in 1 second
(FEV1)% predicted has declined more than
expected
• George is asked about his use of LABA and SABA
therapy, and he admits to inconsistent use of LABA
maintenance therapy and difficulty in using his inhaler
• An office demonstration of how he is using the LABA
inhaler shows that his technique is poor, and, as a result,
it is unlikely that much of the medication is reaching the
lungs
• George is prescribed a LABA using a nebulizer
• He is educated on the need to use the maintenance
therapy and to reserve rescue medication only for
breakthrough episodes
16
17
Case Study 1—Follow-up
COPD
• At the next visit 3 months later, George expresses
satisfaction with the nebulizer and its ease of use
• He reports needing less rescue medication and having
fewer symptoms. He is able to help around the house
and has even begun taking a short walk every morning

Epidemiology of COPD
Epidemiology of COPD
• ~14 million American adults have been diagnosed with
COPD1
• COPD death rate increased 102.8% between
1970 and 2002
– The true prevalence is probably higher because many
individuals with mild grade COPD remain asymptomatic2
• 63% of adults with expiratory airflow obstruction are not
aware of their problem
– Among the 6 leading causes of death, only COPD and DM had
an increase in the death rate
• Death rate in DM increased 3.2% during that time period
– Death rates decreased in heart disease (-52.1%), cancer
(-2.7%), accidents (-41%), and stroke (-63.1%) between 1970
and 2002
• Chronic and unspecified bronchitis accounts for 11.7
million visits to physicians’ offices, hospital outpatient
clinics, and emergency departments (ED) annually1
– Other COPD accounts for 6.1 million visits
• COPD is the third leading cause of death in the U.S.3

COPD—Disease Course
COPD—Assessment
• The natural course of COPD is variable
• COPD is a progressive disease
• COPD is a chronic, incurable disease, but treatment can
reduce symptoms, increase exercise tolerance, improve
quality of life (QOL), reduce exacerbations, and perhaps
decrease mortality
• Spirometric assessment
– However, the correlation between FEV1, symptoms,
and impairment of a patient’s health-related QOL is
weak

COPD—Assessment
COPD—Classification
• Symptom assessment
• Revised 2011 GOLD Guidelines published in December
presented a new system for classifying COPD
– Modified British Medical Research Council (mMRC)1
questionnaire
• Measures breathlessness
• Score ranges from Grade 0 (only get breathless with
strenuous exercise) to Grade 4 (too breathless to leave the
house or breathless when dressing or undressing)
– COPD Assessment Test (CAT)1
• 8-item unidimensional measure of health status impairment1
– Score for individual items ranges from 0 (best) to 5
(worst)2
• Designed to be relevant worldwide1
• Total score ranges from 0-401

Pharmacologic Interventions
Bronchodilators
Includes respiratory muscle training, exercise training, strength and endurance training
Include beta2‐agonists, anticholinergics, and methylxanthines; short acting reserved for rescue; long‐acting used for maintenance for moderate to severe COPD
Inhaled Corticosteroids (ICS)
Influenza and antipneumococcal vaccines may reduce hospitalization due to influenza and pneumonia
Decreases exacerbation frequency in patients with an FEV1 < 60% predicted; does not modify long‐term decline of FEV1
Phosphodiesterase‐4 (PDE‐4) Inhibitors
For patients with significant hypoxemia or evidence of pulmonary hypertension, peripheral edema, or polycythemia; has been shown to increase survival
Improves FEV1 in patients treated with a bronchodilator; reduces moderate and severe exacerbations in patients treated with corticosteroids
Combination Therapy
Beta2‐agonists used with an anticholinergic or theophylline may improve lung function and health status; combining an ICS with a LABA may improve lung function, health status and reduce exacerbations

COPD—Impact of Treatment
GOLD Guidelines on Management of Stable COPD
• Regular and proactive maintenance in primary care
rather than reactive care is beneficial to older patients
with chronic respiratory diseases, reducing the risk of
hospitalization and death
GOLD Guidelines on the Management of Stable COPD, December 2011
• Overall approach to managing stable COPD should be
individualized to address symptoms and improve QOL
• Bronchodilator medications central to the symptomatic management
of COPD (Evidence A)
– Given on as needed basis or on regular basis to prevent or reduce
symptoms and exacerbations
• Principal bronchodilator treatments (Evidence A)
– β2-agonists,
– Anticholinergics
– Methylxanthines, used singly or in combination
• Theophylline is not recommended as first-line therapy

Case Study 2
Polling Question
• Gayle H., a 63‐year‐old receptionist for a pediatrician has been controlled on her SABA rescue medication since being diagnosed with Grade B*
COPD 3 years ago. She smoked half a pack of cigarettes for 35 years and quit at diagnosis. She also suffers from early stage Parkinson’s disease (PD) and hypertension.
• Medications:
– Levodopa for Parkinson’s Disease
– Angiotensin‐converting enzyme (ACE) inhibitor
– SABA
• She uses her SABA rescue medication more and more frequently. Recently, she has been unable to work in her garden, even for a short while, and says she sometimes gets breathless at work and has to take a break and use rescue medication. In elderly patients with cognitive problems and/or physical
disabilities, what device would you typically prescribe for maintenance therapy?

*Grade B, typically GOLD 1 or GOLD 2 and/or 0‐1 exacerbation per year and mMRC grade ≥ 2 or CAT score ≥ 10.
6
Case Study 2—Course of Action
Case Study 2—Follow-up
• Gayle has hand control issues due to the PD, and,
therefore, a LABA using a nebulizer is prescribed
• At a follow-up visit 3 months later, Gayle reports fewer
symptoms of COPD and less use of rescue medication
– Due to PD, she experienced specific problems with
activation, coordinating activation with inhalation, and
positioning her SABA inhaler
• Nebulizers require minimal patient cooperation and
coordination
• Two major issues in Gayle’s stable COPD management:
– General Issue: Under use of maintenance therapy
– Gayle Specific issue: Delivery of the medication
• She is educated on the need to use the LABA regularly,
as prescribed, and to reserve the SABA as rescue
medication for acute symptoms

COPD—Adherence to Maintenance
LABAs and LAMAs (cont)
• Fear of complications may prevent greater use
of long-acting bronchodilators
• Adherence to maintenance regimens is also poor
– Among patients prescribed long-term therapy with
LAMA, LABA, or fixed-dose combinations of ICS and
LABA, a substantial proportion switch therapy
• Persistence, even including those who switch, is
low
– Persistence rates with any long-acting drug at 1, 2,
and 3 years has been found to be 36%, 23%, and
17%, respectively, in an analysis of a large
pharmaceutical database
– There was a small but significant increase in asthma-related
deaths with salmeterol in asthma patients, raising concerns
about LABA monotherapy in asthma patients1
– This increase was not noted in children and adolescents using
formoterol along with concomitant ICS or other LABA/ICS
combinations2,3
• However, COPD is a different disease, occurring in a different
population1
– Safety of LABAs is well-established in the COPD population1,4
– Some increased risk is associated with beta2-agonists in patients
with COPD and concomitant congestive heart failure,1
particularly if they are not treated with a cardioselective betaantagonist

Complications From Poor
Maintenance Therapy
Rescue Therapy—SABAs and SAMAs
• Appropriate use of SABAs and SAMAs
– These agents act more quickly than the LABA
salmeterol and LAMAs, and, therefore, are
appropriate as symptom-driven rescue therapy1
• Inappropriate use
– Frequent use of SABAs or SAMAs is a sign of poorly
controlled disease
– SABAs and SAMAS do not provide long-acting relief
of symptoms; in patients with moderate to severe
COPD, they should be used solely as rescue
medication in conjunction with maintenance therapy
with long-acting bronchodilators2
• Failure to adhere to GOLD Guidelines results in
– More frequent exacerbations
– More frequent hospitalizations

Identifying Patients Exhibiting Signs of
Poor Control or Nonadherence
Identifying Patients Exhibiting Signs of
Poor Control or Nonadherence
• Biomarkers
• Evaluating the frequency, severity, and duration of exacerbations
– The only accepted biomarker in COPD is FEV1; however, this
proves less than optimal in many cases for monitoring response to
treatment1
– Exacerbations begin to occur in more severe disease (Grades C & D)1
• Consider re-evaluation of current treatment in patients with frequent
exacerbations (i.e. 2 or more per year)
– COPD Assessment Test—8 items, scored from 0 to 52
• Covers the domains of cough, phlegm, chest tightness, exercise
limitations, limitations of ADLs, sense of confidence, sleep
disturbances, level of energy
• Score of 10 or more indicates a level of symptoms warranting more
aggressive management
– Markers of exacerbation severity3
• Arterial carbon dioxide tension and breathing rate associated with
the severity of COPD exacerbations
– Some promising biomarkers are on the horizon, but clinical data
are not consistent1
• Serum PARC/CCL-18 independently associated with health
outcomes2
• ECLIPSE cohort3
– Fibrinogen, surfactant protein D, and CC-16 may be useful
– More research is needed to determine if these can provide
information about disease phenotype, severity, and/or
progression
• Phenotypes—COPD is a complex and heterogeneous disease4
– In some cases, phenotype may help predict response to
treatment5

COPD—Difficult-to-Treat Patients
COPD—Difficult-to-Treat Patients
• Disabilities may be a barrier to adherence
and disease control1
• Subpopulations of difficult-to-treat COPD patients make disease
management a challenge
– Elderly patients may have cognitive deficits that make
adhering to medication regimens more difficult1
– They may have physical disabilities, such as poor vision or
osteoarthritis, that may make opening medication
packages, reading directions, or effectively operating
medication delivery devices difficult1
– The presence of comorbidities may increase cognitive
effects and physical difficulties as well as require multiple
medications that may decrease adherence1
– COPD itself may affect cognition negatively, particularly in
the elderly2,3
– Elderly1
• Have more comorbidities
• Disorders such as those of the cardiovascular and musculoskeletal
systems (cachexia, muscle dysfunction, osteoporosis) and
psychological disorders (depression and/or anxiety) are common in
COPD patients, and can complicate treatment
– Twenty-five percent of those over age 65 years suffer from 2 of the 5
most common chronic diseases (including COPD) and 10% have 3 or
more; in those 75 years and older, those figures rise to 40% and 25%,
respectively2

COPD Medication Delivery Devices
COPD Medication Delivery Devices
•
• DPI
Number of different types of devices available
• Pressurized metered-dose inhaler (pMDI)
– Breath-actuated device designed to reduce difficulty encountered with
pMDIs; convenient, compact, portable device providing rapid medication
delivery; has dose counter, indicating amount of medication remaining;
some DPIs emit inspiratory-flow signals to prompt proper technique and
adherence
• Single- and multi-dose devices
– Requires the patient to generate sufficient inspiratory force in order to
deaggregate the powdered medication formulation
• The rate of ineffective inhalation due to inadequate peak inspiratory
flow (PIF) correlates with patient age and severity of airflow
obstruction
– Elderly patients with severe COPD may not be able to achieve
adequate inspiratory flow against the resistance of the device
– Requires PIF rate >30 L/min through the device
– Humidity or inappropriately blowing into the device may cause clumping
of powdered medication, resulting in ineffective delivery of medication
• Advantages include multiple dosing (≥100 doses/canister), shorter
administration time, compactness and portability of the device
• An important disadvantage is the requirement of a specific
inhalation technique, which requires adequate patient coordination
– Multiple steps involved
– Most common error is the failure to synchronize inhalation with
pMDI actuation
– 26% of patients demonstrate inadequate breath holding
– 19% have overly rapid inspiration leading to oropharyngeal
deposition instead of pulmonary delivery
• Even with proper technique, pMDIs deposit only 10%-20% of
labeled dose to the lungs, while much of the medication remains in
the mouth and oropharynx
– This can lead to adverse events
• Use of spacer devices eliminates need to coordinate inhalation with
actuation, but spacers are bulky and increase time for medication
delivery

COPD Medication Delivery Devices
COPD Medication Delivery Devices
• Soft Mist Inhaler
• Nebulizers
– Easiest for patients to use, requires minimal cognitive ability and no
hand-breath coordination, manual dexterity, or hand strength; visible
mist may give patients confidence in medication delivery
• Three types—compressor-driven jet nebulizer, conventional
ultrasonic nebulizer, and high efficiency vibrating mesh nebulizer
(quieter and allows for faster medication delivery)
• However, conventional ultrasonic nebulizers do not readily
aerosolize drug suspensions
– Relatively long duration of medication delivery, poor portability, need for
daily cleaning, and trouble and cost associated with proper maintenance
and replacement of nebulizers
• Cleaning requires disassembling nebulizer and soaking all
components in warm soapy water, rinsing, and air drying before
next use
• Device can last 6 months with proper care, while disposable units
last 2 weeks
– Advantages
• Compact1, portable1, multiple dosing2
• Propellant-free2
• Does not require high generation of inspiratory flow3
• High fine particle fraction2
• High lung deposition (reduced oropharyngeal deposition)2
– Disadvantages
• Requires coordination between actuation and inhalation2
• Requires a slow deep breath and a 10-second breath hold is
recommended2

Higher lung deposition
Negligible residual volumes
Faster rate of nebulization

Cost is comparable to ultrasonic nebulizers but much higher than
conventional jet nebulizers
– Must be cleaned regularly to prevent build-up of deposit and blockage of
apertures; can be challenging to disassemble and re-assemble for
cleaning
– Risk of overdosing using doses approved for use with jet nebulizers
(due to more efficient delivery of medication to the lung)
• Recommendations
– MDI (with or without spacer/holding chamber), nebulizer, and DPI are all
appropriate for delivery of inhaled bronchodilators. Quality of evidence:
good; net benefit: substantial; strength of recommendation: A
– Selection of an appropriate aerosol delivery device for inhaled
bronchodilators includes the patient’s ability to use the device correctly,
patient preference, the availability of the drug/device combination,
compatibility between the drug and the delivery device, the lack of time
or skills to properly instruct the patient in the use of the device or to
monitor its appropriate use, the cost of therapy, and the potential for
reimbursement. Quality of evidence: good; net benefit: substantial;
strength of recommendation: B

Delivery Device Problems in
Select Populations
Delivery Device Problems in
Select Populations
• Physical issues (eg, arthritis, visual problems), the presence of multiple comorbidities, and cognitive issues may compromise a patient’s ability to use a delivery device effectively1
• Deficiencies in inhaler device technique and adherence to treatment regimen may lead to suboptimal health outcomes in COPD patients2
• DPIs require less coordination, but the patient must be able to
generate a certain minimum PIF rate (> 30 L/min) through the
resistance of the device that some older patients may not be able to
achieve1,2
– PIF rates decline with age1
– Evidence also suggests that up to 40% of patients aged > 65
years do not use DPIs correctly3
– Effects of incorrect use of DPIs
• Chronic cough, wheezing, and poorer health-related QOL
associated with incorrect inhalation technique in patients with
asthma4
– User technique, particle size, and type of delivery device affect the efficacy of inhaled medications1
– Evidence indicates that only 36% of elderly patients use an MDI properly1
• Technique is affected by cognitive impairment and physical disability1
• Can be difficult to coordinate actuation and inhalation3
• Use of a large volume spacer (LVS) can improve the patient’s ability to use this device1

Use of Nebulizers in
Subgroups of Patients
Efficacy and Safety of Maintenance Therapy
• Nebulizers may be preferable in certain subgroups of patients
– Elderly1
– Those with severe disease and frequent exacerbations1
– Those with physical and/or cognitive limitations1
– Those who fail to respond satisfactorily to treatment with
hand-held inhalers despite adequate instruction2,3
– Financial issues and patient preferences that enhance
adherence may favor nebulized therapy over other inhaler
devices4
• Nebulized medications are a good option for sicker, frailer
elderly patients, and those with cognitive problems1

• Nebulized formoterol vs placebo as add-on therapy to
tiotropium bromide in COPD patients
– At 6 weeks, FEV1 AUC significantly greater in formoterol
group than placebo (1.57 vs 1.38 L [P<.0001])1
– Other lung function measures also improved—FEV1,
forced vital capacity (FVC), and post-dose IC at day 1;
these were maintained through week 61
– Dyspnea also improved after 6 weeks to both a statistically
and clinically significant extent2,3
– AEs occurred in 37% of formoterol group vs 51% of
placebo group; the most common AEs in the formoterol
group were acute bronchitis (3.8%), COPD exacerbation
(2.6%), and dyspnea (2.6%)1

Efficacy and Safety of Maintenance Therapy
Safety of Long-Term Use of LABAs in COPD
• Nebulized formoterol, 12-month open-label trial
• Review of clinical efficacy and safety of nebulized
formoterol in COPD1,2
– 569 subjects with COPD received twice daily 20 μg formoterol inhalation
solution for nebulization or 12 μg formoterol fumarate DPI for 52 weeks
– Adverse effects (AEs) and safety profile similar between treatment groups
• AEs experienced by 73% in nebulizer group and 78% in DPI group
– Majority of AEs were mild to moderate in severity and unrelated
to treatment
• Exacerbation experienced by 15.8% of nebulizer group and 17.9% of
DPI group
• No clinically important changes in vital signs and no treatment-related
increases in cardiac arrhythmias, heart rate, or QTc prolongation
• Death occurred in 1.3% and more than 1 serious AE occurred in 16.2%
of nebulizer group, compared with 1.9% and 17.9% of DPI group,
respectively
– 12-week and 1-year studies reveal AEs similar to placebo
and formoterol DPI
• Indacaterol vs formoterol + budesonide or salmeterol +
fluticasone3
– Meta-analysis indicated indacaterol 150 ug* and 300 ug*
were comparable to formoterol + budesonide and
salmeterol + fluticasone for measures of lung function
health status and to salmeterol + fluticasone for
breathlessness
*FDA‐approved indacaterol dose is 75 ug once daily for COPD; 150 ug and 300 ug doses are Donohue JF, et al. Ther Adv Respir Dis. 2008;2:199‐208.

Patient and Caregiver Training
and Education
Strategies for Improving Adherence
and Disease Control
•
• Critical factor in appropriate use of inhalers1,2,3
– Evidence indicates that teaching interventions substantially
increase the likelihood of proper inhaler use4
– Physicians should review patients’ inhaler technique regularly to
ensure that adequate amounts of medication are being
received2,5,6
– Education of caregivers is important as well, as many patients
rely on caregivers
– Self-management education has been associated with a
reduction in hospital admission, with no indication of adverse
effects7
• Odds ratio, 0.64; 95% confidence interval, 0.47 to 0.89
– Training of the patient in the use of inhaler devices often is
poorly addressed8
Use of the appropriate device tailored to the needs of the individual
patient
– Improves patient adherence and ability of patient to use the inhaler
correctly, thereby increasing the likelihood of achieving optimal
outcomes1
– Cost considerations may play a role as well1
• Medications administered using pMDI or DPI devices require
Medicare Part D
• Medicare Part B covers 80% of the cost of nebulizer equipment
and medication, which may make it the more affordable option
– Patient preference should be considered as well1,2
• Survey of 82 patients using nebulizers found that adherence
was high, and reported adverse effects minor and infrequent;
patients felt the benefits of the nebulizer outweighed the
disadvantages3

Conclusions
• COPD is a chronic, progressive disease
• Proper management of the disease can reduce acute
exacerbations, hospitalizations, and symptoms, and improve
QOL for patients
• Maintenance therapy is underutilized overall
• Some populations of patients, such as the elderly, cognitively
impaired, or physically disabled, may have difficulty using
maintenance medication delivery devices, even when
maintenance therapy is prescribed, and thus may receive less
than optimal amounts of medication
• Failure to use maintenance therapy appropriately may result
in increased acute exacerbations, hospitalizations, and costs
• Careful consideration of patient factors in selecting medication
and delivery devices can improve patient outcomes
