ADEQUACY OF INHALER TECHNIQUE IN THE PATIENTS OF COPD AND ASTHMA
Objectives: Determining the adequacy of Inhaler technique in COPD and Asthma patients presenting to pulmonary
ward and its association with response to medication.
Background: Incorrect technique when taking inhaled medications frequently prevents patients with Asthma or Chronic
Obstructive Pulmonary Disease (COPD) from receiving the maximal benefit from their medications. Regardless of the
type of inhaler device prescribed, patients are unlikely to use inhalers correctly unless they receive clear instruction,
including a physical demonstration. New high-quality evidence has confirmed that asthma and COPD control can be
improved by brief verbal instruction and physical demonstration of correct inhaler technique, taking only a few minutes
and repeated regularly.
Methodology: Eighty patients were enrolled from the Medical unit of Hatyatabad Medical complex from Oct 2014 to April
2015. All the patients were using metered dose inhalers (MDI) for their asthma or COPD control. Their technique of using
the inhaler was directly observed by the same doctor. They were asked about the response/ benefits of the inhalers.
Results: There were 80 participants,48 with asthma and 32 with COPD.66.25% used standard pressurized metered dose
inhaler with spacer and 33.75% pMDI alone. The majority of patients received their initial inhaler technique instruction
from their doctor .Over half of the participants did not recall having their inhaler technique rechecked. About forty-four
percent (43.75 %) of the patients exhibited correct inhaler technique.
Conclusion: More than half of the patients do not know the exact method of inhaler use. Therefore the patients usually
