Brief Summary
This study will compare the absolute and relative effectiveness of asthma management in patients on inhaled corticosteroid (ICS) maintenance therapy as either extra-fine-particle or larger-particle formulation beclomethasone dipropionate (BDP) via metered-dose inhalers (MDIs) using the propellant hydrofluoroalkane propellant (HFA-BDP), namely Qvar® MDI compared with Clenil® MDI.

Study Arms (6)
IPDI EF HFA-BDP
Patients initiating inhaled corticosteroid therapy as extra-fine HFA-BDP MDI at the index date
IPDI SP HFA-BDP
Patients initiating inhaled corticosteroid therapy as standard particle HFA-BDP MDI at the index date
IPDA SP HFA-BDP

IPDA EF HFA-BDP
Patients increased inhaled corticosteroid therapy as extra fine particle HFA-BDP MDI at the index date
IPDS SP HFA-BDP
Patients increased inhaled corticosteroid therapy as standard particle HFA-BDP MDI at the index date
IPDS EF HFA-BDP

Interventions
IPDI cohort intervention = initiation of intervention drug; IPDS cohort intervention = switching from baseline inhaled corticosteroid therapy to intervention drug without a change in baseline inhaled corticosteroid dose; IPDA cohort intervention = increase in baseline inhaled corticosteroid drug as intervention drug
IPDI cohort intervention = initiation of intervention drug; IPDS cohort intervention = switching from baseline inhaled corticosteroid therapy to intervention drug without a change in baseline inhaled corticosteroid dose; IPDA cohort intervention = increase in baseline inhaled corticosteroid drug as intervention drug
Eligibility Criteria
All patients are aged between 4-80 years and have evidence of asthma and subsequent therapy.
You may qualify if:
- Aged: 4-80 years
- Paediatric cohort (aged 4-11 years), and
- Adult cohort (aged 12-80 years )
- Evidence of asthma and current asthma therapy:
- All cohorts (IPDI, IPDS, IPDA):
- a diagnostic code for asthma, and / or \*≥2 prescriptions for asthma at different points in time during the prior year and/or IPDI only: ≥2 prescriptions for asthma therapies during the outcome year, including ≥1 ICS prescription in addition to that received at IPD
- IPDA and IPDS only:
- ICS prescription in the baseline year, and
- other asthma prescription during the baseline year.
- \*Evidence of "current therapy":
- prescription for ICS during the outcome year (i.e. ≥1 prescription in addition to the prescription at index date
- Have at least one year of up-to-standard (UTS) baseline data (prior to the IPD) and at least one year of UTS outcome data (following the IPD).
You may not qualify if:
- Had a COPD read code at any time; and/or
- Had any chronic respiratory disease, except asthma, at any time; and/or
- Patients on maintenance oral steroids during baseline year
- Received a combination inhaler in addition to a separate ICS inhaler in the baseline year; and/or
- Received ICS therapy during baseline year via DPI (IPDA and IPDS cohorts only).
- If they received multiple ICS prescriptions on the same day at IPD or immediately before
