The proportions of patients with age≥8O years old， smoking，concurrent diabetes melitus，concurrent coronary heart disease，Glucocorticoid use > 7 days，invasive operation and fuzzy state of consciousness in the infection group were higher than those in non-infection group （ P<0.05 ），and the hospitalization time was longer than that in non-infection group （ P<0.05 ）.Multivariate logistic regression analysis results revealed that age≥8O years old， glucocorticoidus>ys，ospialatiti，siveeationdfusateofsiossreallidepedentcto respiratory tract infection in elderly patients with respiratory system diseases （ P<0.05 ）.Conclusion Gram-negative bacteria are the mainpathogenicbacteriaofrespiratorytractifectioninlderlypatientsithrespiratorysystemdiseases，andstrengthentheoitoring andcontrolofindependentriskfactorsiliicalpracticeducethsfespiatoryactifectionilderlyatientsihspatrydiseases，and improve the prognosis of patients.
