Abstract:
Objective To analyze the occurrence and risk factors of infection in inpatients, and explore the effective measures to control hospital infection.
Methods The electronic medical records of 13 027 discharged patients from January 2015 to December 2016 were retrospectively analyzed.Based on the results of relevant report of clinician and investigation of full-time staff in infection department, the incidence rate of infection and its influencing factors were analyzed.
Results The incidence rate of infection was 2.70% (352/13 207).The incidence rates of infection in 2015 and 2016 were 2.89% and 2.93%, respectively, and the difference of which was not statistically significant (P>0.05).The main departments of infection were ICU, urology and neurology.The most common locations of infection were the upper respiratory tract, lower respiratory tract, urinary tract and gastrointestinal tract, and surgical incision infection also accounted for a certain proportion.In addition to fungi, 1 180 strains of pathogenic bacteria were isolated.The infection bacteria were mainly the gram negative bacteria, Escherichia coli, Klebsiella Pneumoniae, Pseudomonas aeruginosa and so on, and the gram negative bacteria accounted for 69.66% (822 strains).The results of logistic regression analysis showed that the ventilator use, tracheotomy, indwelling catheter and hemodialysis were the independent risk factors of hospital infection (P < 0.05 to P < 0.01).
Conclusion To control hospital infection, the high-risk factors should be analyzed according to the hospital's situation, and then the prevention and control should be emphasized.The main measures of control infection include the strict implementing disinfection system, strengthening basic nursing work, rational use of antibiotics, and enhancing the hand hygiene compliance of doctors and patients.
