Prevalence characteristics and influencing factors of COPD in Chengdu, 2019-2020 / 公共卫生与预防医学

ABSTRACT

Objective To explore the characteristics of chronic obstructive pulmonary diseases (COPD) in Chengdu from 2019 to 2020 and analyze its influencing factors. Methods A total of 362 patients with COPD from January 2019 to January 2020 in Chengdu Fifth People's Hospital were collected, and the patients’ medical records were analyzed. The patients’ gender, age, number of hospitalizations, days of hospitalization, disease classification and other information were extracted and analyzed. Results A total of 362 COPD patients were included in this study, including 293 males, accounting for 80.94% of the total. The number of COPD patients over 60 years old was significantly higher than that of patients under 59 years old, with the largest age group being 60 to 79 years old and a median age of 72 years old. The average hospitalization times and days were (8.22±8.75) times and (11.03±5.47) days, respectively. Most patients had COPD of grade II or grade III, accounting for 62.83% of the total. In this study, there were 490 cases of complications occurring in 362 patients, with 1.35 complications per capita. There were 394 cases of respiratory diseases, 74 cases of cardiovascular diseases, and 22 cases of other diseases. The incidence of pulmonary infection was the highest (204 cases, 56.35%), followed by bullae and asthma (83 cases and 64 cases, 22.93% and 17.68%, respectively). The proportion of antiasthmatic drug use was the highest and the use time was the longest, which was 220 times (60.77%) and (10.50±6.23) days, respectively. There were 119 cases (32.87%) treated with antibiotics for (7.85±5.21) days. The anticoagulants were used for 105 times (29.01%) and (7.54±3.18) days. Logistic regression analysis showed that smoking history, passive smoking history, age over 50 years old, family history of respiratory disease and respiratory disease history were independent risk factors for COPD. Conclusion The majority of COPD patients in Chengdu from 2019 to 2020 were male, with the highest incidence in the age group of 60-79 years. Pulmonary infection and other respiratory diseases were the most common complications. Antibiotic use met the guidelines.
