Abstract:

Objective

Current evidence shows that serum electrolyte levels play an important role in the occurrence and development of chronic obstructive pulmonary disease (COPD), but the research on its correlation with the poor prognosis of patients with acute exacerbation of chronic obstructive pulmonary disease (AECOPD) is still limited. Therefore, this study aimed to investigate the correlation between serum electrolyte levels and poor prognosis in patients with AECOPD, in order to provide new clues for the prognosis management of AECOPD.

Methods

This retrospective study ultimately included 535 AECOPD patients admitted to Lanzhou University First Hospital from October 2021 to May 2023. Serum electrolyte levels (sodium and calcium) were assessed as exposure factors, while the poor prognosis of AECOPD (presence or absence of readmission within one year) served as the outcome factor. Cox regression analysis, subgroup analysis, sensitivity analysis, and Kaplan-Meier survival analysis were used to evaluate the correlation between serum sodium and calcium and the risk of readmission within one year.

Results

Compared with patients non-readmitted within one year, readmitted patients had lower sodium and higher calcium levels (P<0.05). Multivariate Cox regression analysis confirmed that lower sodium and higher calcium levels were independently associated with the risk of readmission within one year (P<0.05). Most of the subgroup analyses and the two sensitivity analyses also consistently confirmed the robustness of the association. Finally,Kaplan-Meier survival analysis showed significant differences in cumulative risk of readmission within one year among different sodium and calcium groups (P<0.05).

Conclusion

Serum sodium and calcium levels are independently associated with the risk of readmission within one year in patients with AECOPD,suggesting that serum electrolyte levels may have important clinical value in the prognostic management of AECOPD patients.
