Effects of complications associated with chronic obstructive pulmonary disease on lung function and hospitalization expenses: A retrospective study

Abstract

This study investigates the impact of complications associated with chronic obstructive pulmonary disease (COPD) on pulmonary function and inpatient medical expenditures in the Zhongshan region. A retrospective analysis of data from January 2012 to December 2021 was conducted, focusing on lung function and hospitalization expenses for COPD patients (n=272). The included cases were initially categorized into a simple group (without comorbidities, n=99) and a nonsimple group (with comorbidities, n=173). Changes in lung function within each subgroup over a decade were evaluated, along with the average annual hospitalization rate, average duration of hospital stay, and mean hospitalization cost for COPD patients. A comparison between the simple group and the nonsimple group of COPD patient's uncovered statistically significant distinctions (P
