What is bronchodilator testing?

Bronchodilator testing will be performed using albuterol, a beta 2-adrenergic bronchodilator which is FDA approved for use in persons aged 4 years and above. Exclusion criteria based on contraindications to albuterol use have been developed based on standard criteria used in other pulmonary function survey research studies, and on product safety information. If the participant passes the initial automatic review of bronchodilator eligibility by the ISIS system, the participant will then be seen by the MEC physician who will evaluate the participant and make a final determination on bronchodilator eligibility based on study exclusion criteria. The physician evaluation consists of verification of the participant’s status with respect to key examination data (pulse, blood pressure, pregnancy status) and additional interview questions. For the latter, proxy informants will be necessary for children 6-15 years of age. Additionally, at this time, the MEC physician may exclude any participant from bronchodilator testing if in their judgment the use of albuterol appears otherwise contraindicated. If the participant is eligible and testing is indicated (the participant is not excluded), then specific written informed consent (see Appendix A) will be obtained. Then the physician will instruct the participant in the use of the spacer and albuterol inhaler. Once the medication is administered, the participant must wait for a minimum of 10 minutes for the medication to take effect before proceeding with repeat spirometry.

What is an exclusion criteria for bronchodilator testing?

A number of bronchodilator medication exclusion criteria relate to prescription medications that the participant may currently be taking. A particular class of drugs may in and of itself constitute an exclusion criterion; or the use of certain prescription drugs in persons with certain co-morbidities may constitute an exclusion criterion. Prescription medication data for each participant is collected in the household interview (SI-RXQ) and is automatically coded according to Multum™ drug class by the ISIS system in about 90 percent of cases. In these cases the ISIS will automatically exclude participants from bronchodilator testing if they are taking certain classes of medications.

What are the side effects of beta 2 bronchodilators?

The most common transient side effects of beta 2-adrenergic bronchodilators include tachycardia, increased blood pressure, arrhythmia, and nervousness. These side effects are usually temporary; however, safety precautions are in place to exclude persons with pre-existing tachycardia, elevated blood pressure, or major arrhythmias from bronchodilator testing. Beta 2-adrenergic bronchodilators are thought to convey an increased risk of arrhythmia in persons taking medications such as MAO inhibitors, or tricyclic antidepressants. Beta 2-adrenergic bronchodilators also may cause hypokalemia, increasing the risk of arrhythmia. Persons taking certain types of diuretics who are not taking potassium supplements are excluded from bronchodilator testing.

What is the FEV1/FVC% of a bronchodilator?

For sample persons aged 8-79 years, the FEV1/FVC% LLN is defined by NHANES III data6 and for children aged 6-7 years it is the reference equations defined by the study of Wang et al.7 When the ISIS system selects the participant for bronchodilator studies, the spirometry technologist will read the following script, which explains the reason for the referral to the MEC physician:

What is reversibility testing?

Reversibility testing with a beta2-adrenergic bronchodilator is being used in the current NHANES to help distinguish between asthma and fixed chronic obstructive pulmonary disease (COPD). It is also being used to establish the best attainable lung function among sample persons who have airflow obstruction. For example, bronchodilator reversibility testing will help to determine the prevalence of poorly reversible airflow obstruction, which is a more objective measure of COPD than the simple reduction of airflow rates measured at baseline spirometry. It also permits estimation of prevalence of fully reversible airflow obstruction, which is usually caused by asthma. The health outcome measures obtained from combining pre- and post-bronchodilator spirometry results using the ATS and GOLD recommendations1,2 will enable a more precise estimation of societal burden of COPD and asthma, which
