Evaluation of Inhaler Techniques among Bronchial Asthma Patients Attending a Tertiary Care Hospital in India.

Shivaraj. B. Patil, Sachin Patil, Vikas Joshi, Rajat Mishra, Pradeep J, Prashant Dass.

Background: Inhaled bronchodilator therapy is often used in the treatment asthma. When the technique of inhalation is poor, the drugs are often not delivered appropriately to the site of action leading to poor treatment outcomes. Therefore this study was undertaken to evaluate the use of inhaler technique among asthma patients in India.
Materials and methods: 108 asthma patients using inhaler device who consented for the study were recruited and their demographic data, education, history of asthma and treatment were recorded. Thereafter, an inhaler administration checklist was then used by the investigators to assess the technique of use of the inhalers.
Results: Out of 108 asthma patients, 58 were males. 31 patients used dry powder inhaler (DPI) and 77 patients used pressurized metered dose inhalers (pMDI). Only 17 (22.1%) patients using pMDI and 13 (41.9%) patients using DPI completed all the steps of their respective inhaler technique. Patients with higher educational status are more likely to use the inhalers more accurately. Most common error in the use of pMDI was step 6 (Trigger the inhaler while breathing in deeply and slowly). For DPI the most common error was step 6 (Inhale deeply and forcefully).
Conclusion: This study showed that majority of asthma patients used their inhalers inaccurately. There is need for increased awareness among all the health‑care personnel involved in asthma care to ensure that the asthma patients know correct inhaler technique.

Key words: Pressurized metered dose inhaler, DPI, Inhaler device
