Impact of educational intervention on pressurized metered dose inhaler technique among undergraduate medical students

Background: Inhaled medications form the cornerstone for the management of Asthma and related diseases. Proper technique of pressurized metered dose Inhalers (pMDIs) has proven to be associated with higher level of control of these conditions. Medical personnel who are responsible for training patients must themselves be proficient with usage of pMDI. This study evaluated the outcome of different educational interventions regarding the correct usage of pMDI. Methods: An interventional study was carried out with 60 second year medical students in department of pharmacology, HIMS, Hassan from June to August 2015. Pre and post intervention (after one week and one month) was evaluated based on National Asthma Education and Prevention Program (NAEPP) criteria for the use of pMDI by written and demonstration methods. The interventions included a video clip, an information leaflet and demonstration by a trained faculty. Results: Overall mean scores in pre-test for written knowledge and skill demonstration are 2.13±1.49 and 3.78±1.06 .There was substantial improvement in post intervention scores 7.15±1.41 and 7.37±1.67 (p
