Introduction: Bronchial asthma and chronic obstructive airway disease are the two most common chronic lung diseases encountered at C.U.Shah Medical College. The treatment usually includes the use of bronchodilators and steroids, which are best, delivered through the inhalational route. Metered-dose inhalers are routinely prescribed for this purpose. Metered dose inhalers (MDIs) are an affective modality of treatment for fast relief from asthma flare-ups and other symptoms, and are often used by asthmatic athletes. It has got lots of benefits and some drawbacks depending on usage technique. With proper technique and training drawbacks can be minimized. The aim of this study was to assess the metered dose inhaler technique in patients with chronic lung disease at our hospitals. Method: A cross sectional study was conducted at a Tertiary Health care centre. The inhalation technique was assessed in six steps. Result: Clear evidence showed that only 28% patient could perform all the steps correctly. Percentages of people that followed individual steps properly were: preparation (90%), exhalation (55%), lip closure (70%), inhalation (58%), breath-holding (30%) and puff interval (38%). Conclusion: This study showed that a number of patients in our hospitals were unable to use metered-dose-inhaler properly and therefore indicates the need to make people aware of this technique either by counseling or arranging seminars.
