Assessment of technique of doctors about the use of Metered Dose Inhaler (MDI) in bronchial Asthma & COPD.
Pak J Chest Med Jan ;9(3):13-6.

Inhaled medication is commonly prescribed for the treatment of Asthma and chronic obstructive lung disease, but is often not properly used by the patients. Its correct technique is a prerequisite for proper drug delivery. The incidence of inhaler misuse is high. Unfortunately incomplete knowledge about its proper use is not confined to the patients only. A high proportion of physicians, nurses and pharmacists are also unable to use MDI correctly. A total of 100 doctors ninety males and ten females took part in this study for evaluation of technique about the use of MDI. All adequate technique questions were answered correctly by only 25% of doctors. The most common error was not continuing slow and deep inhalation with activation of canister. It was answered correctly by twenty-five doctors. The question answered best was to keep the MDI mouthpiece between the lips prior to inspiration. It was answered correctly by eighty doctors. The prevalence of incorrect technique is high and is unacceptable. MDI with spacer devices should be used frequently and training courses for family physicians should be arranged so that they should learn proper use of MIDI in the management of Bronchial Asthma and COPD.
