Repeated education regarding the proper use of inhalers can reduce the error rate in inhaler-using patients and improve COPD patients' quality of life. This study investigates the effect of repeated education on the quality of life of COPD patients during the pandemic of COVID-19 from February to June 2020. Repeated education is provided using direct demonstrations to patients through educational media in the form of short videos made by the researchers for each inhaler type. This is a pre-experimental study design which was carried out prospectively at Grha Permata Ibu Hospital, Depok. The quality of life of 22 subjects was examined using the COPD assessment test (CAT) questionnaire. Each patient was given a direct verbal demonstration of the appropriate use of the inhaler. One month later, each patient was provided further education using less than 2 min of video sent to them online via the WhatsApp application. Final quality-of-life examination and assessment of inhaler technique were carried out three months after the initial examination. Assessment of proper inhaler technique was carried out using a specific checklist regarding the use of inhaler translated by the researcher. Before and after delivery of repeated education, the mean CAT score showed a decrease of two points, i.e., 12.8 ± 1.3 and 10.8 ± 2.0, respectively. This indicated that quality of life of the patients had significant improvement. However, as many as 63.6% of patients still made mistakes in using inhaler even though they had been educated. For DPI-type inhalers, mistake mostly happened at step "breath out gently, away from inhaler". For pMDI-type inhalers, mistake mostly happened at step "while holding breath, remove inhaler from mouth". It can be concluded that repeated education regarding proper inhaler technique with direct demonstrations and further maintained by videos can improve the quality of life in COPD patients.
