Appropriateness of metered-dose inhaler use in the Yemeni community pharmacies

Objectives: Metered Dose Inhalers (MDI) are widely prescribed for patients with asthma and Chronic 'Obstructive Pulmonary Disease (COPD). Clinical response to inhaled medication depends on the inhalation technique of the patient. Incorrect technique prevents patients from getting the maximal benefit from their medicines. Inadequate skill in the use of inhalation devices by pharmacists has been well documented. The current study aims to investigate the appropriateness and correct use of MDIs use among community pharmacists and pharmacy technicians in community pharmacies in Sana'a Yemen. Methods: A cross-sectional study was done among the community pharmacies dispensers (pharmacists and pharmacy technicians) in the capital city of Sana'a Yemen, during the period from 1st July 2011 to 26th August 2011. A Simulated Patient (SM) approach was used to investigate the appropriate use of MDIs. Results: Out of 232 participants included in the analysis, 33 (14.2%) were pharmacists and 199 (85.8%) were pharmacy technicians. There was significant difference between the pharmacists and pharmacy technicians in terms of their knowledge of MDI appropriate use (p-value = 0.000). Generally pharmacy technicians had a poor knowledge. On other hand half of pharmacists had a reasonable knowledge of appropriate use of MDI. Experience and age play major role in the appropriate use of MDI. Conclusion: Majority of community pharmacies dispensers have a poor skills of MDI appropriate use. The results of this study recommend the need for interventional educational programs among community pharmacists to improve their counselling skills.
