Learning objectives At the end of the session attendees will be able to discuss: The evidence demonstrating the clinical and economic comparative effectiveness of SIT Potential gaps in SIT access, coverage, reimbursement, and utilization Adherence to immunotherapy: problems and potential solutions 3
Discussion points The Present Increased body of evidence demonstrates the clinical and economic comparative effectiveness of SIT However, SIT access, coverage, reimbursement, and utilization has not gained ground The Past Must be critically evaluated to identify gaps Can direct our course The Future Requires identification, understanding, collaboration, learning, and then education Identify constituents Understand needs that will compellingly support AIT value propositions for each constituent Collaborate so that outcomes of efforts are meaningful Learn!!! Then educate… The role of AIT as “preventive care” may be key Poor adherence (even in the face of extraordinary efficacy) always = failure This needs to be addressed for AIT adoption /acceptance by the non-A/I health care community 4
Trends in Total Annual AR-Related Expenditures: 2000 to 2005 5 % Distribution of Total U.S. AR-Related Expenditures Prescription medications consistently account for over half of U.S. AR-related health care expenditures Shares in treatment type have not changed despite increase in published research demonstrating benefits of SIT Soni A. Allergic rhinitis: Trends in use and expenditures, 2000 and 2005. Statistical Brief #204, 2008. Note that dollars originally reported in USD 2005 were adjusted o USD 2010 values using the U.S. Department of Labor Bureau Consumer Price Index for Health Care (http://data.bls.gov/cgi-bin/surveymost?cu) .
Trends in the U.S. Estimated Prevalence of AR: 2000 and 2005 6 Based on the Household Component of the Medical Expenditure Panel Survey Respondents reported experiencing related symptoms, visiting a physician, or obtaining a prescription drug to treat allergic rhinitis. Total U.S. AR-related expenditures nearly doubled from 2000 to 2005 U.S. Estimated Prevalence of AR: 2000 and 2005 85% % of Total U.S. Population $ Billions 22 Million In both 2000 and 2005, more females reported experiencing allergic rhinitis than males (7.6 percent versus 4.9 percent in 2000 and 8.2 percent versus 6.4 percent in 2005).Differences between females and males significant (P<.05) for both 2000 and 2005.

SLIT: What About Adherence/Compliance? Swim With Dolphins, Cut DepressionDesignA trainer directed half of each session; patients played freely with the dolphins during remainder Control group was given an equal amount of attention from human staff. Results. Greater reduction in mean severity of the depressive symptoms in the dolphin therapy group than in the control group
Children’s compliance with allergenimmunotherapy according to administration routes Open study 1998 to 2003 comparing SCIT (1886 pts), SLIT (806 pts), LNIT (82 pts) 1234 hospital setting, 1540 private Coverage for immunotherapy services varied per region “Noncompliance” SCIT 10.9% vs SLIT 21.5% (p<.0005) Panjo et al JACI 2005;116
Comparison of Reason for Discontinuation Of Immunotherapy Between Different Administration Routes Panjo et al JACI 2005;116:1380-81
SLIT Compliance Design: Survey of 433 pollen & dust mite pts with AR ± asthma to asses compliance with daily SLITonemonodose containers
Compliance assessed by unscheduled telephone calls during 3rd and 6th month of therapy.
76.3% of pts at 3 months
74.8% at 6 months
By coverage status: higher compliance group:
81% of full coverage group
70% of partially covered group
82% of pts with no coverage
How adherent to sublingual immunotherapy prescriptions are patients? The manufacturers' view Collected the Italian sales figures from 2 large manufacturers representing 60% of AIT market
Number of SLIT treatments sold in 2006 as first prescriptions,
How many of the same SLIT prescriptions were prescribed as renewals in subsequent years, until 2009.
In Italy SLIT is a named patient product, and each treatment sold can be tracked

Public and Private Payer “Push Back”: The Zero-Sum Game Oregon Medicaid, Spring 2010 Prioritized List: AR on Line 573 Below the current funding line (Line 502) “Most patients with AR will not qualify for any treatment for the condition. Patients who also have asthma have immunotherapy available to them on Line 11.” PRIORITIZATION OF HEALTH SERVICES A Report to the Governor and the 76th Oregon Legislative Assembly 2011 Condition: SPASTIC DYSPHONIA Treatment: MEDICAL THERAPY Line: 584 Condition: MACROMASTIA Treatment: BREAST REDUCTION Line: 585 Condition: ALLERGIC RHINITIS AND CONJUNCTIVITIS, CHRONIC RHINITIS Treatment: MEDICAL THERAPY Line: 586 (line 574 in 2008) Condition: CANCER OF LIVER AND INTRAHEPATIC BILE DUCTS Treatment: LIVER TRANSPLANT 21
Health Economics of SIT (15 Studies from 1995 to 2011) 22 Poor outcomes for SIT are shown in red font. AR = allergic rhinitis; Clin = clinical; FU = follow-up; MR = medical records review; RC = retrospective claims analysis; SDT = symptomatic drug therapy; SIT = allergen-specific immunotherapy; SLIT = sublingual immunotherapy.
Pharmacoeconomics of allergen immunotherapy compared with symptomatic drug treatment in patients with allergic rhinitis and asthma Method: 30 pts (mean age, 35 yrs ) with Parietaria-induced rhinitis & asthma randomized to SCIT (20 pts) or medications (10 pts) for 3 years Inclusion: PST >5 mm wheal, AR + Ashma (GINA class 2 or 3) for 2 years Evaluated before treatment and annually for 6 years in the pollen period Nose, eyes, and lung symptom scores, and drug consumption via patent diary Economic costs: pt registered monthly:# of medical visit, medications, allergy injections Ariano et al, Allergy Asthma Proc 2006;27
Pharmacoeconomics of allergen immunotherapy Significant improvement in symptom scores and medication use after 1st year of treatment Ariano et al, Allergy Asthma Proc 2006;27
Sustained significant reductions in cost beginning in the 3rd year subcutaneous allergen immunotherapy Results: significant difference in costs favor of SIT vs control 15% the second year 48% the third year (80% reduction ) 80% reduction maintained up to 6th year, 3 years after stopping immunotherapy Net saving per patient: $830/year. Conclusion: SCIT has significant economic advantages over pharmocotherapy alone Ariano et al Allergy Asthma Proc 2006;27
U.S. Health Economics of SIT 26 AR = allergic rhinitis; RC = retrospective claims analysis; SDT = symptomatic drug therapy; SIT = allergen-specific immunotherapy.
Donahue 1995: Patients with AR completing 3.5 years of SIT incurred higher health care costs than those with <3.5 years of SIT (not adjusted for baseline differences in disease severity and costs)
Sullivan 2000: $8,851/5 years = $1,770 annual benefit for SITvs SDT among patients with AR
Hankin 2008: $401/6 months = $802 median annual benefit for SIT(children with AR in the 6 months after SIT discontinuation vs 6 months prior to SIT initiation)
Hankin 2010: $1,625/18 months = $1,218 mean annual benefit for SITamong children with AR vs match controls not receiving SIT
Hankin 2011: 7,286/18 months = $5,465 mean annual benefit for SITamong adults with AR vs match controls not receiving SIT
Background: Florida Medicaid (1997-2008)
Computerized Florida Medicaid claims records contain
HIPAA-compliant unique patient identifiers Basic demographics (e.g., sex, age, and race/ethnicity) Family identifiers (e.g., mother-child) Health services use ICD diagnosis and HCPCS/CPT treatment codes By settings, dates, physician specialties NDC prescription drug claims Include doses, quantities filled, dates of fill Primary and secondary insurers (e.g., Medicaid with Medicare or self-pay ) 27

Matched Cohort Study in Children Florida Medicaid data set from 1997-2007
Definition of Terms:
AR = ICD-9 code 477.X. IT = CPT 95115, 95117, 95120, 95125,95144, 95165, 95180, and 95199.
Newly diagnosed AR = those whose first AR diagnosis was preceded by a full year in which no AR diagnoses occurred
De novo immunotherapy = first documented immunotherapy claim followed (rather than preceded) their first AR diagnosis
Analysis: Data were highly skewed Wilcoxon signed rank tests to compare the groups’ 18-month median per-patient health care use and costs Health care components included total inpatient stays, total outpatient visits , total pharmacy fills, and total health care use. 32 Hankin CS, Cox L, Lang D, Ann Allergy Asthma Immunol2010;103:79-85.

Managed Care Round Table and Working Group (2006) Payers from the public and private sectors were unaware of SIT as preventive care Although overwhelmed by the costs for treatment of asthma, were not familiar with disease-modifying potential of SIT Specialty expertise required Patient identification and evaluation Testing Preparation and administration Monitoring Documentation and record-keeping 43 Once informed, they “connected the dots” to acknowledge
SIT as preventive care
Agreed that SIT could mitigate the high costs and burden of asthma
Substantial barriers to access to treatment
Poor coordination of care
Primary care’s lack of awareness and low referral rates
Called upon the specialty to “assume a leadership role in collaborating with primary care physicians to educate them regarding the benefits and risks of immunotherapy and appropriate referral of patients with allergic rhinitis.” Levin A, Eavy G, Burgoyne D, Bordeaux M, Hankin CS. Allergy Immunotherapy Working Group consensus statement. Drug Benefit and Trends2008;20:14-20.
Public and Private Payer “Push Back”: Fighting Back Presentations and letters to Oregon Medicaid’s medical director, Health Services Commission (Ariel K. Smits, MD MPH) spearheaded by David Coutin “At this point, additional literature on the effectiveness of treatments for allergic rhinitis would not be helpful.” “The Commission...would be interested in information regarding how treatment of allergic rhinitis impacts healthy life years, burden of suffering, impacts on vulnerable populations, need for medical care, and our other prioritization criteria.” I've spoken again w Director of Oregon HSC. The Commission accepts the findings of Hankin and Cox, but has a rather common issue with Federally Qualified Health Centers (FQHC) payment methodologies for allergy injections, as does Florida. FQHC, where most of medical assistance (MA) patients in OR receive care. They are under federal mandates to bill MA for Dr visits for all encounters with MA patients, thereby driving up overall costs to states to deliver IT Rx. 44
SIT as Preventive Care 2010 Patient Protection and Affordable Care Act (PPACA) Mission: to identify and reduce the incidence of preventable chronic illness and disability “Preventive Clinical Services” designation U.S. Preventive Services Task Force (USPSTF) supported by the U.S. Department of HHS AHRQ Based on rigorous, evidence-based methods to evaluate the expected net health benefit (benefit minus harm) associated with delivery of a specified service As of September 2010, all new insurance policies fully cover preventive care and screening services that receive a USPSTF grade of A or B No patient co-pays or deductibles can be applied to the cost for these services

Conclusions AIT is effective and cost-effective but underutilized Reasons for underutilization are likely multi-factorial with patient factors being significant but payers may begin to restrict access Much more needs to be done to identify, understand, collaborate, learn from, and educate stakeholders and decision-makers Identify constituents Understand gaps that will compellingly support intended value propositions for each constituent Collaborate so that outcomes of efforts are meaningful The role of SIT as “preventive care” may be key Poor adherence (even in the face of extraordinary efficacy) always = failure Several A/I organization sponsored efforts focused on enhancing adherence, and evaluating preventive and cost-efficacy of AIT 58
