Study Type

Study Type

Describes the nature of a clinical study. Study types include interventional studies (also called clinical trials), observational studies (including patient registries), and expanded access.
Observational

Enrollment (Actual)

Enrollment

The number of participants in a clinical study. The "anticipated" enrollment is the target number of participants that the researchers need for the study.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

12 years to 64 years (Child, Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

Sampling Method

Non-Probability Sample

Study Population

Health plan members with asthma aged 12 to 64 years receiving two or more prescriptions for BFC or FSC during 6/1/2007-9/30/2010 who are naive to ICS/LABA combination therapy.

Description

Inclusion Criteria:

  • Continuous health plan enrollment for 12 months before and after index Rx
  • At least two prescription fills for BFC or FSC within 12 months
  • Asthma claims diagnosis, and 12 to 64 years of age at the time of first prescription

Exclusion Criteria:

  • Evidence of COPD
  • Claims diagnosis of any of inflammatory diseases or cancer
  • Presence of Rx for more than one type of ICS/LABA combination on index date
  • Chronic steroid use or Xolair use prior to ICS/LABA index treatment

Cohorts and Interventions

Advair
FSC patients new to ICS/LABA combination therapy

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Rate of asthma exacerbations
Time Frame: 12 months
The rate is defined as the total number of asthma exacerbations for all patients in the cohort divided by the total number of person years. An asthma exacerbation is defined as any of three conditions: Asthma related inpatient hospitalization or Asthma related emergency department visit or Oral corticosteroid use.
12 months
Asthma Related Inpatient Hospitalizations
Time Frame: 12 months
12 months
Asthma Related Emergency Department visits
Time Frame: 12 months
12 months
Use of Oral Corticosteroids (OCS)
Time Frame: 12 months
A pharmacy claim for any of the OCS medications
12 months

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Asthma controller medication use (SABA, ICS, LABA, LTRA, XOLAIR, THEOPHYLLINE)
Time Frame: 12 months
Asthma controller use (0 vs. 1 and total number of fills for each).
12 months
Asthma Related Healthcare Utilization
Time Frame: 12 months
Asthma Related Healthcare Utilization: Outpatient/office visits, Inpatient length of stay, ICU admission and length of stay.
12 months
Asthma Related Healthcare costs
Time Frame: 12 months
Asthma Related Healthcare costs (plan paid, patient paid and plan + patient paid)costs of all Asthma related medication and Asthma related outpatient/office, ED and Inpatient visits.
12 months

These dates track the progress of study record and summary results submissions to ClinicalTrials.gov. Study records and reported results are reviewed by the National Library of Medicine (NLM) to make sure they meet specific quality control standards before being posted on the public website.

Study Major Dates

Study Start

Study Start

The actual date on which the first participant was enrolled in a clinical study. The "anticipated" study start date is the date that the researchers think will be the study start date.
June 1, 2012

Primary Completion (Actual)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.

Study Completion (Actual)

Study Completion

The date on which the last participant in a clinical study was examined or received an intervention/treatment to collect final data for the primary outcome measures, secondary outcome measures, and adverse events (that is, the last participant's last visit). The "anticipated" study completion date is the date that the researchers think will be the study completion date.
