Pulmonary Disease, Chronic ObstructiveNCT01615783
Clinical and Economic Burden of Patients With Chronic Obstructive Pulmonary Disease in a Medicaid Population
An observational study of Pulmonary Disease, Chronic Obstructive, run by GlaxoSmithKline.
Trial summary
Reports suggest that the Medicaid population includes a higher percentage of smokers than the general population. A high prevalence of smokers in a population is likely to lead to a higher burden of chronic obstructive pulmonary disease (COPD). Read more about this study

Study population: Medicaid recipients (aged >=40 years) diagnosed with COPD (International Classification of Disease, Ninth Revision, Clinical Modification (ICD-9 CM) codes: 491.xx, 492.x, 496.xx) and newly initiated on Chronic Obstructive Pulmonary Disease (COPD) maintenance medication (maintenance therapies include ipratropium alone/combination ipratropium-albuterol (IPR), tiotropium (TIO), inhaled corticosteroid (ICS), long-acting beta-agonist (LABA), and combination product of inhaled corticosteroid and long-acting beta-agonist (ICS/LABA)) will be identified and matched in a 1 to 3 ratio to non-COPD Medicaid recipients on age (exact), gender, race, index year, Medicare dual eligibility, pre-index long-term care use. Index date was defined as the date of the first chronologically-occurring COPD maintenance medication during an identification period (01/01/2004 to 12/31/2006) for COPD patients, and as the date of the first medical or prescription claim during the index year of the corresponding matche

About this study
Reports suggest that the Medicaid population includes a higher percentage of smokers than the general population. A high prevalence of smokers in a population is likely to lead to a higher burden of chronic obstructive pulmonary disease (COPD). Few studies have evaluated the economic burden of COPD in a Medicaid population. The objective of this observational, retrospective cohort study is to estimate the economic burden of COPD in subjects with a COPD diagnosis who are enrolled in Medicaid and are receiving maintenance treatment covered by Medicaid.
Specifically, the null hypothesis for the primary outcome measure is that no difference is observed in all-cause costs between subjects with and without COPD. The test hypothesis is that there is a difference in all-cause costs between subjects with and without COPD.

Secondary outcomes to be evaluated include all-cause resource use and COPD-related costs for the COPD cohort.
The study uses a medical and pharmacy administrative claims database called MarketScan Medicaid Database that contains the medical, surgical, and prescription drug experience of nearly 7 million Medicaid recipients. This analysis will use data from 8 states.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Subjects with COPDOther
Medicaid beneficiaries diagnosed with Chronic Obstructive Pulmonary Disease (COPD) and newly initiated on a maintenance medication
Subjects without COPDOther
Medicaid beneficiaries without a COPD diagnosis but having at least one medical or pharmacy claim during each year of the identification period
| Study group | Role | What they receive |
|---|---|---|
| Medicaid beneficiaries | Medicaid beneficiaries with at least one medical or pharmacy claim during each year in the identification period (2004-2006) Receives: Other: Subjects with COPD; Other: Subjects without COPD |
What is being measured
The primary outcome is the main question the study is designed to answer.
Incremental costs of COPD
Mean difference in all-cause costs between subjects with and without COPD. Incremental total costs and components of incremental total costs including pharmacy, medical, and long-term care will be reported
Measured: 1 year
Secondary outcomes (2)
All-cause resource use
The mean number of visits of each type of medical resource use including inpatient hospitalizations, emergency department [ED] visits, physician visits, outpatient visits, home healthcare visits/durable medical equipment, and long-term care visits.
Measured: 1 year
COPD-related costs
Mean total, pharmacy, medical and long-term care costs associated with COPD in the cohort of subjects with a COPD diagnosis

The record says: finished, as of the sponsor's last update on 25 Jun 2012. Status can change between updates, so confirm with the study contact before making plans.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Incremental costs of COPD (time frame: 1 year). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 25 Jun 2012.
