COPD Assessment and Management Bundle Versus Usual Care

Not Applicable

Completed

Conditions: Chronic Obstructive Pulmonary Disease

Interventions: Device: Spirometry test
Drug: Levalbuterol

Registration Number: NCT01833026

Lead Sponsor: University of Illinois at Chicago

Brief Summary: Chronic Obstructive Pulmonary Disease (COPD) is a progressive respiratory (lung) disease that makes it harder to breathe over time. To date, there is no cure for COPD, but it can be managed when diagnosed and proper medical care is provided.

The purpose of this study is to determine if diagnosis and guided therapy with the use of spirometry is related to better patient outcomes (the condition of a patient's health) compared to usual care which may or may not include the use of spirometry. Spirometry is a standardized test used in medical practice that measures how much air your lungs can hold and how forcefully you can breathe out.

For this study, the investigators will compare two groups: 1) intervention (treatment) group and 2) usual care group (control). The intervention group will have a spirometry test and the results will be provided to the primary care physician. The usual care group will not initially have a spirometry test. Both groups will be followed for outcomes.

Detailed Description: The purpose of this study is to determine if diagnosis and guided therapy with the use of spirometry is related to better patient associated outcomes compared to usual care which may or may not include the use of spirometry. To do this, we propose a comparative effectiveness trial of introducing a COPD assessment and management bundle targeted to primary care providers for patients suspected of having COPD versus usual care.

New physician-diagnosis of COPD and/or new physician-diagnosis of asthma with a ≥10 pack year smoking without a spirometry 4 weeks or more after discharge from diagnosis setting.

Outpatient setting

Any patient with an existing physician-diagnosis of asthma within the past 2 years but > 6 months prior to the time of their visit and a ≥10 pack year smoking history, without a diagnosis of COPD, using a respiratory medication in the past year, and no spirometry on record or had a pre-bronchodilator spirometry with evidence of obstruction on record for at least the past 5 years.

Existing Diagnosis

Any patient planning to move away from the city within the next year.
Seen by a pulmonary specialist in the past 3 years.

Arm && Interventions

Group	Intervention	Description
COPD assessment and management recommendations	Spirometry test	Patients with a physician-diagnosed COPD or asthma suspicious for COPD being managed by the physician randomized to the intervention group will perform a spirometry test and provide information regarding their medical history on their initial visit, which is 90 minutes before their doctor's appointment. A letter containing the interpretation of spirometry test results, and recommendations for guideline based therapy based on GOLD guidelines will be available to the primary care doctor at the time of the patient's clinic visit. The doctor may review the results and use his or her own judgment in moving forward with the subject's diagnosis and management. A copy of the spirometry results and assessment based on the GOLD criteria at the time of the test of your subject will be uploaded to his or her electronic health record for future reference. Outcomes will be assessed every 3 months for up to one year through patient telephone calls and medical chart reviews.
Usual Care	Spirometry test	Patients with a physician-diagnosed COPD or physician-diagnosed asthma suspicious for COPD being managed by the physician randomized to the usual care group will provide medical history, not initially have a spirometry, and will be observed as usual care. Outcomes will be assessed every 3 months for up to one year through patient telephone calls and medical chart reviews. At the conclusion of the research study which will be 12 months from the patients' initial visit, patients being managed by the physician randomized to the usual care group will have a spirometry test and these results will not be shared with the doctor or the patients during the study but will be uploaded to the electronic health record after the end of the study for future reference.

Primary Outcome Measures

Name	Time	Method
Number of Participants With Accurate Classification of Irreversible Airflow Obstruction	spirometry was performed at the first visit for intervention group and at 1 year from recruitment for the usual care group, one time assessment for both groups	accuracy of diagnosis was the outcome measure. The results of the spirometry test (done in the beginning for the intervention group and ant the end of 1 year for the usual care groups) were reviewed in conjunction with the initial physician diagnosis of COPD and/or asthma to confirm whether the diagnosis was accurate, not accurate, or indeterminate. Accuracy of diagnosis of COPD was determined by spirometry results if the FEV1/FVC ratio was \<0.7.
