Brief Summary
This study will compare the absolute and relative effectiveness of asthma management in patients on inhaled corticosteroid (ICS) maintenance therapy as Easi-breathe® (EB) - beclometasone dipropionate (BDP) breath-actuated inhaler (BAI) - and as-needed (prn) reliever medication (short-acting beta2-agonist \[SABA\] therapy) via either a BAI (i.e. Easi-breathe® \[EB\] salbutamol) or via a pressurised metered dose inhaler (MDI) (e.g. MDI salbutamol).

Outcome Measures
Primary Outcomes (2)
Proxy asthma control
Control defined as: * No recorded hospital attendance for asthma, including admission, Accident \& Emergency (A\&E) attendance, out-of-hours attendance, or Out-Patient Department (OPD) attendance, AND * No prescriptions for oral steroids, AND * No GP consultations, hospital admissions or A\&E attendance for lower respiratory tract infections (LRTI) requiring antibiotics.
One-year outcome period
Total number of asthma exacerbations and exacerbation rate ratio
Where exacerbation is defined as an occurrence of: * Unscheduled hospital admissions / A\&E attendance for asthma, OR * Use of oral steroids
One-year outcome period
Secondary Outcomes (3)
Treatment success 1
One-year outcome period
Treatment success 2 (independent of possible cost savings)
One-year outcome period
Respiratory-related hospitalisations and referrals.
One-year outcome period

Interventions
Eligibility Criteria
Asthma patients on SABA therapy (any available) monotherapy who, at the index date, either: (i) IPDI: initiate ICS therapy as BDP EB at the index date and also receive reliever therapy as either\*: * Salbutamol EB, or * Salbutamol MDI, OR, who (ii) IPDA: receive a recorded increase in ICS therapy as BDP EB at the index date and also receive reliever therapy as either\*: * Salbutamol EB, or * Salbutamol MDI.
You may qualify if:
- Aged: 4-80 years:
- Paediatric cohort (aged 4-11 years), and
- Adult cohort (aged 12-80 years )
- Evidence of asthma:
- a diagnostic code for asthma, and / or
- ≥2 prescriptions for asthma at different points in time during the prior year and/ or
- ≥2 prescriptions for asthma therapies during the outcome year, including ≥1 ICS prescription (in addition to that received at IPD) - IPDI cohort only
- Be on current asthma therapy (for the IPDA cohort only):
- ≥1 ICS prescription in the prior year, and
- ≥1 other asthma prescription during the baseline year.
- 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
- received a combination inhaler in addition to a separate ICS inhaler in the baseline year; and/or
- received a long-acting beta2-agonsist (LABA) in addition to a separate ICS inhaler in the baseline year
- received ICS therapy during baseline year via DPI (in IPDA cohort only).
