Background: The Chinese government has promoted the ‘tiered medical services’ policy in which diseases are classified by severity, mode of onset and difficulty of treatment since 2015 to optimize medical resources. We evaluated the diagnosis and treatment of acute exacerbation (AE) of chronic obstructive pulmonary disease (AECOPD) under the tiered system. Methods: We conducted a cross-sectional study. COPD characteristics and treatments were compared among hospitals in different tiers. Associations were examined by univariate and multivariable logistic regression analysis. In addition, multivariate logistic regression was performed to identify the possible influencing factors of antibiotics, glucocorticoids and anticoagulant usages. Results: Eligible COPD patients (n = 432) were consecutively recruited from eight hospitals in different tiers in China. Patients in the countryside preferred the community hospitals, whereas patients in cities preferred second-tier and teaching hospitals when they suffer from AECOPD. It indicates most COPD patients are likely to treat their disease locally. The severity of COPD AE increased with tiers of hospitals (p < 0.001). However, our results clearly show that most community hospitals can only deal with mild exacerbation of COPD. Approximately 90% of AE patients received antibiotics. We speculated that antibiotics abuse might exist in the three tiers of hospitals. Multivariate analysis demonstrated that long-term antibiotics usage (⩾14 days) was associated with moderate exacerbation [odds ratio (OR): 5.295, 95% confidence intervals (CI) 2.248–12.473, p < 0.001], radiographic progression (OR: 2.176, 95% CI: 1.047–4.522, p = 0.037), positive sputum etiology (OR: 3.073, 95% CI: 1.477–6.394, p = 0.003) and increased white blood cells (OR: 2.470, 95% CI: 1.190–5.126, p = 0.015). The proportion of glucocorticoids increased with the hospital hierarchy (18.6% versus 45.6% versus 69.2%, p < 0.001). The proportions of severe cases in the second-tier hospitals were 26.9%; however, non-invasive positive pressure ventilation (NPPV) rate was only 14.7%. Anticoagulant is not commonly used in AECOPD, and the community hospitals had the lowest proportion of anticoagulation regimen (1.7% versus 14.3% versus 20.5%, p = 0.002). Conclusions: The ‘tiered medical services’ policy in AECOPD management has been unsatisfactory in the past years. Irrational treatment strategies in different hospitals were still found when comparing with international guideline. Further reform of the policy is still needed to optimize the management of AECOPD in China.
