Asthma is an obstructive lung disease with high prevalence. Symptom control in asthma remains poor despite significant advancements in treatment guidelines and inhalational devices. This is often attributed to inadequate patient adherence to the inhaler technique and insufficient education on its long-term use. Through this study, we aimed to assess the impact of reinforcement of proper inhaler technique on asthma symptom control and quality of life. A prospective cohort of 400 asthma patients using dry powder inhalers and metered dose inhalers was recruited in the outpatient clinic of our hospital. At the time of recruitment, the correctness of inhaler technique usage was assessed, and the pre-test Inhaler Technique Score (ITS) was recorded for each patient. Then, a ten-step inhalation technique was taught through demonstration, and the post-test ITS score was recorded again. This was done for each patient at monthly intervals for 3 months. Along with it, two tailored questionnaires, the Asthma Control Test (ACT) and Asthma Quality of Life Questionnaire (AQLQ), were administered at each visit to assess disease control and quality of life. Significant enhancements in inhalation technique were noted from the first to the third visit using the ten-step inhalation usage scores, which improved from 6.91 to 9.87 (out of 10) (p<0.001), paralleled by ACT score increases from 17.06 to 19.37 (out of 25) (p<0.001) from visits one to two, and from 19.37 to 20.52 (out of 25) (p<0.001) from visits two to three, signifying improvement in symptom control. Quality of life similarly improved from 4.45 to 5.12 to 5.45 (out of 7) (p<0.001) across the three visits as assessed by AQLQ. In conclusion, promoting proper inhaler technique through structured education programs is crucial for optimizing long-term asthma management and enhancing patients' quality of life.
