Assessing Asthma Control using Asthma Control Test and Spirometry
Journal Title: International Journal of Contemporary Medical Research - Year 2017, Vol 4, Issue 8
Abstract
Introduction: The goal of asthma treatment is to obtain and maintain a good control of symptoms. The focus of asthma control is now shifting to an assessment and treatment approach. This study aimed at assessing asthma control using ACT scores and to determine its relationship with lung function parameters among persons with asthma in the Department of respiratory medicine. Material and methods: It was a cross-sectional study. The study included 66 patients with bronchial asthma proved by bronchodilator reversibility and was conducted over a period of two years. The ACT was administered to assess the control of asthma. Spirometric test was done in patients using a portable spirometer. Results: As per Asthma control test 80% had well controlled asthma while 20% had uncontrolled asthma. As per analysis with spirometer (FEV1) 68% had uncontrolled asthma while 32% had asthma under control. The Pearson correlation coefficient in the relationship between ACT and FEV1 (% predicted value) was 0.5., with moderate correlation between ACT and spirometry. The intra-class correlation the η (eta) value was found to be >0.011 which was not significant. Conclusion: Our study showed that the results of the asthma control test did not match with the results of spirometric analysis. Thus, FEVI by itself is not a reliable tool measuring of asthma control. ACT is a simple method that addresses multiple clinical dimensions of control that are relevant to the well – being of the patient and provides a quantitative assessment of asthma control.
