Abstract：Objective To investigate the pathogenic bacteria distribution and the influencing factors of nosocomial infection in patients with mental illness over 60 years old.Methods Review method was used to analyze 1 806 psychiatric patients, and according to the period of nosocomial infection, the infection of 1 806 patients were divided into the infection group (88 cases) and the non-infection group (1 718 cases). The incidence of nosocomial infection and pathogen distribution of psychotic patients were observed and analyzed, and at the same time single factor and multiple factors were used to screen related risk factors for nosocomial infection.Results Among the 1 806 psychiatric patients, the incidence of nosocomial infection was 4.87% (88/1 806), and the main infection site was urinary tract infection and respiratory tract infection. Among the 88 infected patients, 8 pathogenic bacteria were isolated and cultured, with 16 strains, and the positive detection rate was 18.18% (16/88), among which 4 strains of gram-positive bacillus accounted for 25.00%. 12 strains of gram-negative bacillus accounted for 75.00%, and shigella infection was common. Through unconditioned Logistic multi-factor analysis, adverse drug reactions (OR=5.233, P=0.025), combined basic diseases (OR=4.406, P=0.031) and invasive operations (OR=5.590, P=0.030) were the main risk factors for nosocomial infection in patients with mental illness.Conclusion Gram negative bacteria are the main pathogenic bacteria in nosocomial infection of elderly psychiatric patients with a greater incidence of nosocomial infection, mainly in the urinary tract and respiratory tract. According to related risk factors, we should improve the quality and skills of nursing staff, strengthen the prevention and treatment of underlying diseases, reduce drug adverse reactions, and then reduce the nosocomial infection occurrence.
