Abstract
Background and ObjectiveChronic obstructive pulmonary disease (COPD) is a leading cause of morbidity and mortality worldwide. We aimed to evaluate the temporal trends in hospitalization and mortality from acute exacerbation of COPD (AECOPD) and the associated financial costs over a 10-year period in Beijing, China.MethodsHospital admission records from 2008 to 2017 for all patients aged ≥20 years with a primary discharge diagnosis of AECOPD were retrieved from the Beijing Public Health Information Center Database. Joinpoint regression was used to analyze trends and calculate the annual percentage change (APC) and average annual percent change (AAPC) for AECOPD hospitalization and mortality.ResultsA total of 337,802 AECOPD cases were recorded from 2008 to 2017. An inverse U-shaped trend in the AECOPD hospitalization rate was observed, showing an increase from 150.2 per 100,000 inhabitants in 2008 to 218.7 per 100,000 inhabitants in 2014 (APC: 5.5%, 95% CI: 2.9–8.2), before declining to 161.13 per 100,000 inhabitants in 2017 (APC: −9.7%, 95% CI: −16.0 to-2.9). In-hospital mortality from AECOPD decreased significantly from 3.91% to 2.21% (AAPC: −11.4%, 95% CI: −15.5 to−7.0). A decline in the median length of hospital stay from 13.0 days in 2008 to 12.0 days in 2017 (Ptrend < 0.001) was accompanied by a decrease in the use of mechanical ventilation from 2012 to 2017 (Ptrend < 0.001). However, the total hospitalization cost per case increased from 15953.5 yuan (USD $2281.4) to 19874.5 yuan ($2842.1) during the same period.ConclusionAECOPD remains a heavy burden on the health care system in Beijing. Strategies to better manage COPD and reduce hospitalizations from AECOPD are needed.
