Clinical characteristics and changes in inhaled drugs of newly diagnosed patients with chronic obstructive pulmonary disease in some hospitals in Hunan and Guizhou from 2017 to 2023
Objective To compare the clinical characteristics and changes in inhaled drugs of newly diagnosed chronic obstructive pulmonary disease(COPD)patients in some hospitals in Hunan and Guizhou from 2017 to 2023,in order to further understand the current status of COPD diagnosis and treatment.Methods This cross-sectional study included stable COPD patients who were initially diagnosed in the respiratory and critical care departments of 13 hospitals in China from January 1,2017 to December 31,2023.They were divided into 7 groups based on the time of their initial visit:the 2017,2018,2019,2020,2021,2022,and 2023 groups.Basic information of the patients,the percentage of forced expiratory volume per second(FEV1％pred),FEV1/forced vital capacity(FVC),COPD assessment questionnaire(CAT)scores,the number of acute weightings in the past year,and inhalation drug regimens were collected.Results The CAT scores of patients with COPD who visited from 2017 to 2019 were significantly higher than those from 2020 to 2023(all P＜0.05);The FEV1％pred and FEV1/FVC of patients with COPD showed an increasing trend from 2017 to 2023;The proportion of patients using long-acting muscarine anticholinergic(LAMA)gradually decreased between 2017 and 2023,with 8.0％(134/1 665)of patients with COPD using single drug LAMA in 2023.The proportion of patients using double branch dilators has been increasing year by year in 2018,2019,2020,and 2021,and the proportion of patients using double branch dilators for COPD has stabilized in 2021,2022,and 2023,with no statistically significant difference between groups(P＞0.05).The proportion of patients with COPD who used triple inhalation drugs was the lowest in 2020 and 2021(P＜0.05).In 2017,2018,2019,2022,and 2023,the proportion of patients with COPD who used triple inhalation drugs was 45.2％(364/806),54.0％(730/1 352),55.5％(742/1 337),45.8％(717/1 565),and 51.1％(851/1 665),respectively.The compliance with inhalation prescriptions and Global Initiative for Chronic Obstructive Pulmonary Disease(GOLD)documents for newly diagnosed patients with COPD from 2017 to 2023 was 47.9％(386/806),35.1％(474/1 352),33.7％(451/1 337),40.3％(405/1 005),31.2％(372/1 193),28.4％(445/1 565),and 58.8％(979/1 665),respectively.Conclusions With the migration of time,the clinical symptoms of newly diagnosed COPD patients have been alleviated,indicating a trend of forward shift in treatment time;The proportion of double bronchodilators used has increased,and the proportion of triple inhaled drugs used is relatively high.The compliance with GOLD documents is still not ideal.
