Abstract
Background and Decreased efficacy of metered dose inhaler and dry powder inhalers are
Aim of Study: associated with errors in inhalational techniques.
The aim of the study: to study the association of errors in the technique for using
two types of inhalers with demographic and other variables.

Material and Methods: Five hundred adult patients with respiratory diseases who were currently using
an inhaler device were enrolled in this study. Patient’s demographics and
duration of inhaler therapy and assessment of inhaler technique were recorded by
interview and direct observation.

Results: Out of 500 enrolled patients, 465 patients were using the device with wrong
technique. Among 465 patients, 188 patients were using metered dose inhaler and
277 patients were using dry powder inhalers. Technical errors were common in
both the devices but more common with metered dose inhaler device. Failure to
exhale before the inhale through device was most common error with metered
dose inhaler (68.6%) and dry powder inhalers (71.4%). Association of errors with
female gender is seen in both metered dose inhaler and dry powder inhalers users.
Reduction in the numbers of errors is seen with increase in the duration of therapy
and regular training on follow-up visits.

Conclusions: Dry powder inhalers and metered dose inhalers are commonly used in
management of respiratory patients. Therefore, the errors in using these devices,
technique and handling errors are common in both dry powder inhalers and
metered dose inhaler users. More error was found in old age, female and short-
term users. However regular training on follows up visits can solve this current
problem.

Keywords: metered dose inhaler, dry powder inhalers, inhalational technique, technical
