Prognostic risk factors in elderly patients with type 2 diabetes mellitus complicated with pulmonary infection
Objective To investigate the pathogenic bacteria distribution and prognostic-related factors in elderly pa-tients with type 2 diabetes mellitus(T2DM)complicated with pulmonary infection.Methods A retrospective study was con-ducted on the clinical data of 196 elderly patients with T2DM complicated with pulmonary infection who received hospitalization treatment in People's Hospital of Daxing District from September 2017 to September 2022.Their clinical data and pathogenic bacteria identification results were analyzed.They were divided into survival group(136 cases)and death group(60 cases)ac-cording to their prognosis.The distribution of pathogenic bacteria was compared between the two groups and the related factors affecting the prognosis of patients were explored.Results A total of 219 strains of pathogenic bacteria were isolated from these 160 elderly patients.Among them,23 ones(14.38% )were simultaneously infected with two types of pathogenic bacteria,and 7 ones(4.38% )were simultaneously infected with three types of pathogenic bacteria.The types of pathogens included 139 strains of Gram-negative bacteria(63.47% ),67 strains of Gram-positive bacteria(30.59% ),and 13 strains of fungi(5.94% ).There was no statistically significant difference in the distribution of pathogenic bacteria between the death group and the survival group(P＞0.05).Multivariate logistics regression analysis showed that ALB＞40 g/L,CRP＞10×109/L,FBG＞12.79 mmol/L,hypoxemia,pathogenresistanceandmultipleinfectionswereindependentriskfactorsfordeathinelder-ly patients with T2DM complicated with pulmonary infection(P＜0.05).Conclusion ALB,CRP,FBG,hypoxemia,patho-gen resistance and multiple infections may be the main factors affecting the prognosis of patients.Clinical attention should be paid to prevention and control.
