Abstract Objective To investigate the nosocomial infection rate of psychiatric patients in our hospital, analyze the risk factors of nosocomial infection, and summarize the value of standardized intervention in preventing nosocomial infection.Methods A retrospective analysis was made on the clinical data of nosocomial infection in 1 400 inpatients with psychosis admitted to our hospital from June 2016 to January 2019. On January 1st, 2018, the whole hospital began to implement standardized intervention as a time node. Before the time node, 690 patients received were taken as the control group, and routine preventive intervention was given. After the time node, 710 patients were taken as the experiment group, standardized intervention was given, and then related risk factors were analyzed.Results The incidence of nosocomial infection in the experimental group was 4.65% (33/710), and the false negative rate was 0.28% (2/710), which were lower than those in the control group, 10.87% (75/690) and 2.17% (15/690). The difference was statistically significant (P<0.05). The main nosocomial infections in the two groups included the urinary tract, respiratory tract and gastrointestinal tract. The main risk factors for nosocomial infection were: aged over 60 years, schizophrenia, combined with other diseases, hospitalization time 50 days and above, the use of two kinds of antibiotics and above, invasive procedures and adverse drug reactions (OR=2.309, 1.670, 1.898, 1.446, 1.203, 2.061, and 1.790, P<0.05), and the protective factors of nosocomial infection were protective constraints (OR=0.906, P<0.05). The rate of antibacteria use of the experimental group was lower than that of the control group, the daily consumption of disinfectant and hand sanitizer per bed was higher than that of the control group, and the above differences were statistically significant (P<0.05).Conclusion The nosocomial infection rate of mental patients is high, the length of stay in hospital and the age are the risk factors, and the protective constraints are the protective factors.
