Deficiencies associated with the use of inhaler devices for asthma

Objective: To study the deficiencies associated with the use of inhaler devices among children with asthma.

Design: Observational descriptive study

Method: Study population comprised consecutive children seen at all medical clinics of Lady Ridgeway Hospital using inhaler devices for asthma. Study was carried out from February 2008 until 150 patients were enrolled. Data was collected using an interviewer administered questionnaire. Technique of using inhaler was checked. Knowledge about maintenance of the device was assessed.

Results: Of the 150 patients 63% were in the 5-13 year age group. Fifty six percent were using the inhaler for 1-4 years. Seventy one percent in the below 2 year age group used the Holding chamber (Babyhaler). Forty percent in the 2-4 year age group used a volume spacer and a face mask. Eighty four percent in the 5-13 year age group used a dry powder inhaler or volume spacer without the face mask. Steroids alone were used by 84% of children while 16% used combination drugs. Compliance was good in 85%. Technique was satisfactory in 67% cases.

Conclusion: There are major deficiencies in the usage of inhaler devices among patients with asthma.
