Clinical Characteristics of Pathogens Causing Nosocomial Infections in Elderly Patients with Mental Disorders
摘要
Abstract
Objective To investigate the type of pathogens and clinical characteristics of nosocomial infection in elderly patients with mental disorders.Methods 461 elderly patients with mental disorders admitted to the psychiatric department of our hospital from January 1,2015 to December 31st,2016 were selected as the research objects.The clinical data of all patients were analyzed by systematic review method.According to the results of data,the incidence of nosocomial infection in all hospitalized patients was counted,and the main pathogenic bacteria and clinical characteristics of the infected patients were analyzed by related clinical examination results.Results The age and length of hospital stay in the infection group were higher than those in the uninfected group,and the BMI was less than that in the uninfected group,and the difference was statistically significant(P ＜ 0.05).The specimens were examined 140 times,a total of 8 types,25 strains of pathogenic bacteria were isolated and cultured,the positive rate was 17.86％.9 strains of G + bacteria,accounting for 36％;16 strains of G-bacteria,accounting for 64％,of which the most common pathogenic bacteria infection was Salmonella Shigella infection,and G-bacteria infection was more common.Most of the nosocomial infections (71.43％)were the first infection,and the upper respiratory tract infection (45.71％)was the most common;Patients with schizophrenia had the highest proportion of nosocomial infection (62.86％),and winter(41.43％) was the season of high incidence of infection.Multivariate analysis showed that age and length of hospital stay were independent influencing factors for nosocomial infection in elderly patients with mental illness (P ＜ 0.05).Conclusion The main pathogenic bacteria causing nosocomial infections in elderly patients with mental illness are gram negative bacteria,mainly respiratory tract infection,and the length of stay and age are closely related to the occurrence of nosocomial infection.关键词
