The relation between lung functions and quality of life in a sample of patients with COPD in Damascus hospital- a cross- sectional study.

Abstract

Abstract Background Chronic obstructive pulmonary disease (COPD) is a major and increasing global health problem with an enormous amount of expenditure of direct/indirect healthcare costs. The mortality due to COPD is rising and is expected to become the third leading cause of death globally by 2030. Methods this is cross-sectional study conducted in Damascus hospital among Patients diagnosed with chronic obstructive pulmonary disease (COPD). The entry criteria included the patient's age, place of residence, body mass index, also the variables of the place of residence, and educational level. In addition to the personal variables of the participants included in the questionnaire. Results A significant relationship was found between the increase in the number of packs of smoked cigarettes per year and the increase in CAT. The score for patients, where the average CAT for smoking patients was 10–20 packets/year 21.33, while This average reached 39 in 100 smokers Packet/year, so the value is 0.0006 P value. This indicates that there is a strong statistically significant relationship between the increase in the average CAT Score and the number of cans of cigarettes smoked per year. Also, by studying the relationship between CAT Score and patients' FEV1 severity, we found a statistically significant relationship Strong, as the severity increased, and we found an increase in the average value of CAT in patients, as it reached this average of 12 only when the severity was mild, while it was 34.22 when the FEV1 was Very intense, so worth it P value > 0.0001, which indicates a significant relationship between these two variables. Conclusion Chronic obstructive pulmonary disease is one of the pulmonary diseases that affects the individual’s health and personal life. Our study concluded that there is a relationship between both CAT scores and the GOLD classification in patients. GOLD classification refers to forced expiratory volume which can be tested by spirometry
