Abstract
Improper inhalation technique with beta-agonist metered-dose inhalers (MDIs) decreases efficacy of the bronchodilator. The success of demonstrating the correct technique and the pharmacist's role in patient education has been reported. To obtain information regarding the routine patient education practice of pharmacists when dispensing a beta-agonist MDI (albuterol), the following study was performed. Fifty-two prescriptions for an albuterol MDI were presented to 52 randomly chosen community pharmacists in three Tennessee cities. Twenty-six independent and 26 chain pharmacies were evaluated. Pharmacists' practice with regard to patient education, instruction, and demonstration of the correct usage of the MDI was observed and recorded. Overall, 13 percent of the pharmacists initially offered to educate the patient-investigator (PI) regarding the correct usage of the MDI without being asked for information. Fifty-three percent of pharmacists offered information only upon being asked specifically how to use the MDI. Of the pharmacists who offered to educate the PI, 71 percent discussed less than half of the eight steps correctly. Only 1 of the 52 pharmacists actually demonstrated MDI inhalation technique, and this in response to a request. No pharmacist asked the PI to perform the technique while he/she observed. No pharmacist offered information on delivery enhancement devices. Our results demonstrate that few pharmacists educate patients on the correct usage of an MDI, and that many pharmacists are not aware of the correct technique.
