Abstract

Background: AECOPD is a severe status of COPD. The prolonged length of hospital stay (LHS) was associated with poor prognosis and higher medical costs in AECOPD patients. Identification of the risk factors for prolonged LHS will help physicians provide targeted and personalized interventions, reduce LHS, and avoid unnecessary health services in COPD patients. This study aimed to explore the risk factors for prolonged LHS in hospitalized AECOPD patients. Methods: In this multicenter cross-sectional study, 598 AECOPD patients were screened. In the end, the LHS of 111 were <7 days (Normal LHS, N-LHS), 218 were 7-10 days (Mild Prolonged LHS, MP-LHS), and 100 were≥11 days (Severe Prolonged LHS, SP-LHS). Demographic data, underlying diseases, symptoms, and laboratory findings were collected. Multiple logistics regression was performed to investigate the independent risk factors for prolonged LHS in AECOPD patients. Results: The significant differences in 11 variables were found by univariate analysis. Since significant collinearities among white blood cells (WBC), neutrophils (NS), and NS% were observed, WBC and NS% were excluded. Therefore, 9 factors were included in multiple logistics regression. Subsequently, our results identified that the rates of hypertension and chronic cor pulmonale (CCP) were independently associated with prolonged LHS in AECOPD patients. Conclusions: Collectively, our results suggested that complications of hypertension and CCP were at a higher risk of prolonged LHS in AECOPD patients. It also indicated that AECOPD combined with hypertension and/or CCP probably more severe. Then, more extensive management should be initially administrated.
