Evaluation of health-care providers' knowledge in the science of aerosol drug delivery: Educational sessions are necessary

BACKGROUND: Aerosolized drugs are widely used to treat and control a variety of pulmonary diseases. However, there is increasing evidence that patients are unable to use their drug delivery device correctly. The failure of aerosolized treatment is usually the result of poorly communicated instructions. The aim of this investigation was to evaluate the knowledge of health-care providers in the science of aerosol drug delivery (ADD) and assess the impact of further education on their knowledge.MATERIALS AND METHODS: One hundred and seventeen health-care providers attended a 4-hour educational course on ADD science. The course was conducted from June to August 2018 in Jeddah, Riyadh, and Dammam. Pre-course assessment done with a 12-item multiple-choice questionnaire. Post-course assessment was conducted after the end of course in which participants were asked to rate their knowledge of ADD on a scale of 1-10 (before and after the course).RESULTS: Sixty-six health-care providers (physicians, pharmacists, respiratory therapists, and health educators) completed the course. The participants' clinical experience, on average (+/- standard deviation), was 7.6 +/- 7.3 years. Clinical experience favored physicians over other groups. The precourse score for all participants was 3.2 +/- 1.9 out of 12 and the postcourse score was 6.97 +/- 2.7. There was a significant statistical difference between pre- and postcourse assessment scores (P < 0.05). Differences between the four specialties were insignificant (P = 0.216), without a correlation between clinical experience and preassessment scores (P = 0.202).CONCLUSION: The present data indicate that health-care providers' knowledge of ADD is completely inadequate. There is an urgent need to introduce an ADD educational package in the curricula. An annual competency-based evaluation for health-care providers is critical as well.
