A Business Case for Asthma Education

1
A Business Case for Asthma Education
Environmental Interventions

• Polly Hoppin, University of Massachusetts Lowell
• Study Co-investigators Molly Jacobs Laurie
  Stillman

2
Best Practices for Asthma Management
NAEPP/NHLBI Guidelines

• Measures of assessment and monitoring
• Education for a partnership in asthma care
• Control of environmental factors
• Pharmacologic therapy
• New guidelines underscore importance of patient
  education environmental interventions
• Implementation of Guidelines needs attention
• Less headway made on 2 and 3

3
Effectiveness of Asthma Education Environmental
Interventions on Health Outcomes

• Across risk levels
• Increased symptom free days other quality of
  life measures
• Improved lung function
• Reduced use of rescue medications

4
Challenges to Delivering Asthma Education

• Disease highly complex, requiring tailored
  education interventions
• Time in standard office or sick visit
  insufficient
• Limited coverage for discrete asthma education
  visits
• Range of providers not reimbursed

5
Challenges to Delivering Environmental
Interventions

• Evidence of health effectiveness relatively new
• Lack of awareness among clinicians
• Environmental interventions considered beyond the
  scope of medical care
• Lack of evidence regarding cost-effectiveness
• Lack of sustainable funding sources

6
Who is Currently Paying for Environmental
Interventions and Asthma Education?

• Federal Grants
• State Local Health Departments
• Some Private Foundations
• Some Health Plans

7
Why Should the Health Sector Care?

• Nationally Asthma costs over 16 billion in
  direct indirect expenses
• Over 70 of costs borne by the health sector
• Many costs preventable

8
Establishing a Business Case for Health Care
Decision-making

• Are there cost savings?
• Savings from reduced health expenditures exceed
  the cost of the program
• Is there cost-effectiveness?
• Investments in a new service are reasonable for a
  given health outcome

9
Primary Findings

• The health sector stands to benefit from
  investing in asthma education environmental
  interventions
• Education
• Services targeted to high risk patients realize
  cost-savings
• Home-based environmental interventions
• Assessment, services supplies targeted to high
  risk patients are cost-effective

10
Evidence on Costs

• Literature review 1986-2006
• Dozens of research intervention studies
• Fewer rigorous studies (RCT or well-designed
  pre-post)
• Fewer including a cost evaluation
• 16 asthma education studies 2 environmental
  intervention studies
• Additional cost evaluations needed
• Standardized cost evaluation approaches needed

11
Evidence on Costs Education

• Findings Vast majority of studies demonstrated
  cost savings
• Across the 20-years of studies Savings 7 to
  36 for every 1 invested in asthma education
• High risk patients ? lower health service
  utilization? cost savings
• Lower risk patients, not as high health service
  utilization? less cost savings, but increase in
  quality of life measures.
• Studies vary
• Setting clinic, telephone, hospital or home
  individual or group
• of visits 1-8
• Personnel nurse, physician, respiratory
  therapist, medical social worker, health educator
  
• Similar educational content
• basic physiology of asthma
• medications and medication compliance
• asthma triggers and trigger avoidance
• self management techniques

12
Evidence on Costs Environmental Interventions

• Findings Program costs not offset by
  utilization yet evidence of cost effectiveness
  2-28 per symptom free-day gained (SFD).
• Study design
• Setting home
• of visits 5-9
• Personnel environmental counselor community
  health worker
• Interventions
• Home assessment
• Extensive education regarding trigger avoidance
• Mattress/pillow encasements
• Pest abatement
• Vacuum cleaner w/ HEPA filter
• Smoking cessation

13
Are Costs for Environmental Interventions
Reasonable?

• Findings 2-28 per symptom free-day gained
  (SFD)
• Limitations Based on 2 published cost
  evaluations
• Comparison with accepted pharmacotherapy
• 7.50 per SFD for inhaled corticosteroid
• 11.30 per SFD for budesonide
• 523 per SFD for Xolair

14
Evidence on Costs Practice Literature

• Combining asthma education environmental
  interventions in comprehensive asthma management
• Optima Health saved 4.10 for every 1 spent on
  their high-risk member program
• Monroe Plan for Medical Care realized a 20
  reduction in total asthma-related medical costs
• Asthma Network of Western Michigan comprehensive
  care costs 2,500 per person annually saves 800
  per child per year.

Framework for Implementation

Mechanisms for Implementation

• Public and private payers
• Health provider groups
• Employers
• Policy Makers
