The Relationship Between Lung Function, Disease Severity, and Motivation to Quit Smoking Among Chronic Obstructive Pulmonary Disease (Copd) Patients

Background: Smoking cessation is an important management for Chronic Obstructive Pulmonary Disease (COPD), but many patients continue to smoke due to low motivation. Therefore, further studies exploring motivation to quit smoking are needed. This study examines the relationship between lung function, disease severity, and motivation to quit in COPD patients. Methods: A correlational cross-sectional study was conducted at a pulmonary hospital in Yogyakarta, Indonesia, in February 2024. One hundred adults with COPD who were current smokers were chosen through random sampling. We used the validated Richmond Test to measure patients’ motivation to quit smoking, the COPD Assessment Test (CAT) questionnaire to assess the severity of COPD, and Peak flow meters to assess lung function by measuring peak expiratory flow (PEF). We used descriptive statistics to summarize the characteristics of the participants and Spearman's rank correlation to look at the relationships between the variables, with a p-value of less than 0.05. Results: The average age of the participants was 65 years (SD = 10.62), the average length of time they had been smoking was 23 years (SD = 6.94), and the average number of cigarettes smoked each day was 23 (SD = 7.59). Most of the people who took part (61%) showed moderate motivation to quit smoking. Correlation analysis found a significant correlation between peak expiratory flow and the motivation to quit smoking (p = 0.03) and between the severity of the disease and the motivation to quit smoking (p = 0.04). Conclusion: This study finds a significant correlation between motivation to quit smoking, lung function (PEF), and the severity of COPD. These results show how important it is to assess each patient individually when making smoking cessation programs for this group.
