Abstract:
Objective To explore the clinical characteristics and prognostic factors of elderly patients with commu-nity-acquired bloodstream infection(CA-BSI),and provide basis for clinical treatment and prevention.Methods Medical records of elderly patients diagnosed with CA-BSI in a tertiary first-class hospital of Changsha from 2017 to 2021 were collected.Patients were divided into a survival group and a death group according to the prognosis after 30 days hospitalization.The differences in clinical data between two groups of patients were compared,and influen-cing factors for the prognosis in CA-BSI patients were analyzed.Results A total of 575 elderly CA-BSI patients were included in the analysis,with 535 cases in the survival group and 40 cases in the death group.Univariate ana-lysis results suggested that death of elderly CA-BSI patients was related to gender,age,history of hemodialysis,glucocorticoid usage,indwelling catheter,concomitant heart disease,albumin,creatinine,and sequential organ fai-lure assessment(SOFA)score(all P＜0.05).Multivariate logistic regression analysis results suggested that old age(OR=1.062,95％CI:1.016-1.109),high SOFA score(OR=1.161,95％CI:1.067-1.262),glucocorti-coid usage(OR=6.006,95％CI:2.441-14.774)were independent risk factors for the death of elderly CA-BSI patients,while normal albumin(OR=0.942,95％CI:0.891-0.995)was a protective factor.Conclusion Elderly CA-BSI patients have high risks of death.It is necessary to improve the immunity of patients as well as use antimi-crobial agents and glucocorticoids rationally,so as to reduce the risk of death in patients.
