evaluation of the metered-dose inhaler technique among healthcare providers

poor inhaler technique is a common problem both in asthmatic patients and healthcare providers, which contributes to poor asthma control. this study was performed to evaluate the adequacy of metered-dose inhaler (mdi) technique in a sample of physicians and nurses practicing in hospitals of hamadan university of medical sciences. a total of 173 healthcare providers voluntary participated in this study. after the participants answered a questionnaire aimed at identifying their involvement in mdi prescribing and counseling, a trained observer assessed their mdi technique using a checklist of nine steps. of the 173 participants, 35 (20.2%) were physicians and 138 (79.8%) were nurses. only 12 participants (6.93%) performed all steps correctly. physicians performed essential steps significantly better than nurses (85.7% vs. 63.8%, p < 0.05). the majority of healthcare providers responsible for instructing patients on the correct mdi technique were unable to perform this technique correctly, indicating the need for regular formal training programs on inhaler techniques.
