Rana Suzette Bonds, MD The University of Texas Medical Interview with: Rana Suzette Bonds, MD The University of Texas Medical Branch MedicalResearch: What is the background for this study? Dr. Bonds: Both anaphylaxis and asthma can be life threatening disorders requiring prompt treatment. Each disorder can be successfully treated with medication which is delivered by devices designed for self-administration. Unfortunately there has been evidence in the literature that patients frequently do not use the devices appropriately. We sought to determine which factors were associated with incorrect use of metered dose inhalers and epinephrine autoinjectors, and to determine if rates of correct use have improved since earlier reports. MedicalResearch: What are the main findings? Dr. Bonds: Sixteen percent of patients used the epinephrine autoinjector properly and 7 percent of patients used the metered dose inhaler correctly. The most common error with the autoinjector was not holding the unit in place for at least 10 seconds after triggering. For patients using the metered dose inhaler the most commonly missed step was exhaling to functional residual capacity or residual volume prior to actuating the canister. Male sex, Caucasian race, and previous medical education correlated with correct use of epinephrine autoinjector device. (more…)
