NCT01141452

Brief Summary

The objective of this study is to compare the effectiveness, cost-effectiveness and direct healthcare costs of managing chronic obstructive pulmonary disease (COPD) in primary care patients with evidence of COPD who either initiate inhaled corticosteroid (ICS) therapy, or have an increase in their ICS dose, as hydrofluoroalkane (HFA) beclometasone dipropionate (BDP) (hereafter Qvar®), CFC-BDP (hereafter BDP) and fluticasone propionate (FP) via pressurised metered-dose inhalers.

Outcome Measures

Primary Outcomes (2)

  • Total number of exacerbations; exacerbation rate ratio; time to first after IPD

    Where exacerbations are defined as: * Unscheduled hospital admissions / A\&E attendances:\* * For COPD (definite code) and * Lower respiratory tract infections (LRTI) treated with antibiotics * Acute use of oral steroids * Antibiotics use with a lower respiratory read code within a ±5-day window

    Two-year outcome period

  • COPD treatment success

    * No recorded hospital attendance for COPD or respiratory related events (i.e. with a lower respiratory read code), including: * Admission * A\&E attendance * Out of hours attendance * No exacerbations of COPD ("definite" plus "possible" prescriptions as defined above) * No consultations, hospital admissions or A\&E attendance for lower respiratory tract infections (LRTI) requiring antibiotics.

    Two-year outcome period

Secondary Outcomes (10)

  • COPD treatment success factoring in change in therapy

    Two-year outcome period

  • COPD treatment success factoring in change in therapy unrelated to cost savings

    Two-year outcome period

  • Change in ICS dosing

    Two-year outcome period

  • Rate of hospitalisations

    Two-year outcomes

  • SABA usage

    Two-year outcome

  • +5 more secondary outcomes

Study Arms (6)

IPDA FP MDI

Patients who were on inhaled corticosteroid therapy as part of their baseline therapy (any ICS therapy) who, at an index prescription date, stepped-up ICS dose as fluticasone via metered dose inhaler

Drug: Fluticasone propionate metred dose inhaler

IPDA HFA-BDP MDI

Patients who were on inhaled corticosteroid therapy as part of their baseline therapy (any ICS therapy) who, at an index prescription date, stepped-up ICS dose as extra-fine hydrofluoroalkane beclomethasone dipropionate via metered dose inhaler

Drug: Extra-fine hydrofluoroalkane beclomethasone MDI

IPDA CFC-BDP MDI

Patients who were on inhaled corticosteroid therapy as part of their baseline therapy (any ICS therapy) who, at an index prescription date, stepped-up ICS dose as chlorofluorocarbon beclomethasone dipropionate via metered dose inhaler

Drug: Chlorofluorocarbon beclomethasone metered dose inhaler

IPDI CFC-BDP MDI

Patients who were not receiving inhaled corticosteroid therapy as part of their baseline therapy but who, at an index prescription date, initiated ICS as chlorofluorocarbon beclomethasone dipropionate via metered dose inhaler

Drug: Chlorofluorocarbon beclomethasone dipropionate

IPDI HFA-BDP MDI

Patients who were not receiving inhaled corticosteroid therapy as part of their baseline therapy but who, at an index prescription date, initiated ICS as hydrofluoroalkane beclomethasone dipropionate via metered dose inhaler

Drug: Hydrofluoroalkane beclomethasone metred dose inhaler

IPDI FP MDI

Patients who were not receiving inhaled corticosteroid therapy as part of their baseline therapy but who, at an index prescription date, initiated ICS as fluticasone propionate via metered dose inhaler

Drug: Fluticasone propionate metred dose inhaler

Eligibility Criteria

Age40 Years - 80 Years
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)
Sampling MethodNon-Probability Sample
Study Population

Primary care COPD patients who at an index prescription date either initiated ICS therapy as extrafine HFA-BDP, CFC-BDP or FP via MDI or had an increase in baseline BDP-equivalent ICS dose the index data as extrafine HFA-BDP, CFC-BDP or FP via MDI

You may qualify if:

  • Aged ≥40 years at index prescription date
  • COPD diagnosis:
  • diagnostic code, and
  • ≥2 prescriptions for COPD therapy in baseline year (at different points in time)
  • For the ICS increase cohort (i.e. IPDA) ≥1 of these prescriptions must be for ICS therapy.
  • Commence ICS therapy at any time (even if before COPD diagnosis is made)

You may not qualify if:

  • \- A diagnostic read code for any other chronic respiratory disease (except asthma)
