Brief Summary
This study will compare the absolute and relative effectiveness and cost-effectiveness of asthma management in patients in the USA on inhaled corticosteroid (ICS) maintenance therapy as HFA-BDP (Qvar®) pressurised metered dose inhaler (pMDI) compared with fluticasone propionate (FP) pMDI. .

Outcome Measures
Primary Outcomes (4)
Proxy Asthma Control
1. No recorded hospital attendance for asthma, including admission, Emergency Room (ER) attendance or Out-Patient Department (OPD) attendance, AND 2. No prescriptions for acute courses of oral steroids, AND 3. No GP consultations, hospital admissions or ER attendance for lower respiratory tract infections (LRTI) requiring antibiotics.
One-year outcome period
Total number of asthma exacerbations and exacerbation rate ratio
Where exacerbations are defined as an occurrence of: 1. Unscheduled hospital admissions / Emergency Room attendance for asthma, OR 2. Use of acute courses of oral steroids
One-year outcome period
Revised proxy asthma control
No recorded hospital attendance for asthma, including admission, Emergency Room (ER) attendance, out-of-hours attendance, or Out-Patient Department (OPD) attendance, AND No prescriptions for acute courses of oral steroids, AND No GP consultations, hospital admissions or ER attendance for lower respiratory tract infections (LRTI) requiring antibiotics. Average daily, prescribed dose of ≤180mcg salbutamol / albuterol or ≤500mcg terbutaline
One-year outcome period
Risk Domain Asthma Control (in the subgroup of patients aged 12-60, the following additional analysis was done)
Where control is defined as the absence of the following during the one-year outcome period: 1. Asthma-related : * Hospital attendance or admission, OR * A\&E attendance, OR * Out of hours attendance, OR * Out-patient department attendance 2. GP consultations for lower respiratory tract infection 3. Prescriptions for acute courses of oral steroids.
One year outcome period
Secondary Outcomes (6)
Asthma control plus no additional or change in therapy
One-year outcome period
Asthma control plus no additional change in therapy (where change is not driven by possible cost saving)
One-year outcome period
Respiratory-related hospitalizations and referrals
One-year outcome period
Overall asthma control (Risk and Impairment) (in the subgroup of patients aged 12-60, the following additional analysis was done)

Eligibility Criteria
Asthma patients who either: (i) Initiate ICS therapy as one of: * HFA-BDP pMDI * FP pMDI OR (ii) Step up ICS therapy as one of: * HFA-BDP pMDI * FP pMDI
You may qualify if:
- Aged: 5-80 years:
- Paediatric cohort (aged 5-11 years), and
- Adult cohort (aged 12-60 years)
- Non-smokers aged 61-80 years
- Evidence of asthma:
- a diagnostic code for asthma, (ICD 9 codes: 493xx) or
- ≥2 prescriptions for asthma at different points at any time
- Be on current asthma therapy
- ≥1 other asthma prescription during the outcome period
- Have at least one year of baseline data (prior to the IPD) and at least one year of outcome data (following the IPD).
You may not qualify if:
- had been diagnosed with any chronic respiratory disease at any time other than asthma
- received maintenance oral steroid therapy during baseline.
- Aged 12-60 years (paediatrics included in original study - removed to make comparable with USA data)
- Evidence of asthma: a diagnostic code of asthma or ≥2 scripts for asthma in baseline year at different points in time
- Have definite dosing instructions
- Have at least 1 year of up-to-standard (UTS) baseline data before IPD
- Have at least 1 year of UTS outcome data after IPD. Index dates from 1998 onwards were accepted in the study.
- Had a diagnostic read code for chronic obstructive pulmonary disease (COPD) at any time
- Had a diagnostic read code for chronic respiratory disease at any time
- Were on maintenance oral steroid therapy at baseline
