Abstract

Asthma and chronic obstructive pulmonary disease (COPD) patients usually use metered-dose inhaler (MDI) for treatment. MDI device is ineffective if used without correctly used. This study was designed to evaluate patients’ knowledge on asthma and COPD diseases and their MDI salbutamol inhalation technique. A set of questionnaire with 15 questions was given to patients with asthma (n=30) and COPD (n=31) at Institut Perubatan Respiratori to test patients’ knowledge on their disease and this was followed with evaluation on patients’ MDI salbutamol inhalation technique. Descriptive statistics was used to analyse patients’ demographic backgrounds, level of patients’ knowledge on their disease and level of MDI salbutamol inhalation technique. Chi square test and Pearson correlation coefficient were used to analyze the variables. Result showed asthmatic patients having better knowledge (mean=10.30) than COPD patients (mean=8.39). There was no significant difference (p=0.723) on knowledge between asthmatic and COPD patients. Patients for both diseases had inefficient technique (83.6%) while only 16.4% patients were able to demonstrate efficient technique in using MDI salbutamol. There was a strong correlation between level of knowledge and MDI salbutamol inhalation technique (p<0.001) among patients. These findings established that patients should be properly educated regarding their disease and medicine to achieve the optimum result.
