NCT01141465

Brief Summary

This study will evaluate and compare the effectiveness of asthma management in patients with evidence of persistent asthma following a switch in asthma therapy to combination inhaled glucocorticosteroid (ICS) / long-acting bronchodilator (LABA) therapy as either: fixed-combination fluticasone propionate / salmeterol (FP/SAL; Seretide®) via pressurised metered-dose inhaler (pMDI) or dry-powder inhaler (DPI) plus as-needed (prn) reliever therapy (salbutamol as DPI, BAI or pMDI), or fixed-combination budesonide / formoterol (BUD/FOR; Symbicort®) via DPI plus prn reliever therapy (salbutamol as DPI, BAI or pMDI or bricanyl as DPI). The final analysis plan will define exact comparators and age groups to be studied after reviewing baseline data.

Outcome Measures

Primary Outcomes (4)

  • Composite proxy for asthma control

    * 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

  • Exacerbations (total and rate ratio)

    * Unscheduled hospital admissions / A\&E attendance for asthma, AND/OR * Use of oral steroids.

    One-year outcome period

  • GOAL Total Control (proxy measure to replicate total control as measured in the GOAL RCT in a real world patient population

    * No day-time symptoms; * No night-time symptoms; * No exacerbations; * No treatment-related adverse events * PEF ≥80% predicted = "normal" * No SABA use

    6 months (sensitivity analysis at 8 weeks)

  • GOAL exacerbations

    Absence of: * Documented episodes of hospitalisations AND/OR * Exacerbation treatment - oral steroids or antibiotics for asthma over one year

    One year

Secondary Outcomes (4)

  • Compliance with ICS/LABA combination therapy

    One year outcome period

  • Compliance with ICS as part of ICS/LABA combination therapy

    One-year outcome period

  • Treatment success

    One-year outcome period

  • SABA dosage

    One-year outcome period

Eligibility Criteria

Sampling MethodNon-Probability Sample
Study Population

Primary care asthma patients receiving ICS therapy (any of BDP, extrafine HFA-BDP, BUD or FP as pMDI, BAI or DPI) plus as needed SABA reliever therapy who underwent a change in asthma therapy to combination ICS/LABA therapy as FP/SAL (MDI or DPI) or BUD/FOR (DPI) at the same or at least twice the BDP-equivalent dose of ICS prescribed during baseline.

You may qualify if:

  • Aged: 4-80 years: Paediatric cohort (aged 4-11 years); Adult cohort (aged 12-69 years); Elderly cohort (aged 70-80 years.
  • Evidence of asthma: i.e. a diagnostic code of asthma or ≥2 prescriptions for asthma at different points in time during the prior year, including one ICS prescription.
  • Be on current asthma therapy: i.e. ≥1 asthma prescriptions in the prior year, and at least 1 other asthma prescription during the same period.
  • 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:

  • Diagnostic read code for chronic respiratory disease (including COPD) at any time
  • On maintenance oral steroid therapy at baseline
  • Any patients receiving a combination inhaler in addition to their separate ICS inhaler in the baseline year.
