ObjectiveTo understand the use of antibiotics in inpatients and the incidence and trend of hospital infections， to explore the implementation effect of comprehensive management measures， and to provide reference for hospitals to use antibiotics reasonably. MethodsBased on the hospital infection monitoring and management system， a retrospective analysis and comparison were conducted on the use of antibiotics， submission of microbial test samples， and incidence of hospital infections among inpatients in a tertiary hospital from 2012 to 2021. ResultsFrom 2012 to 2021， the use of antibiotics showed a downward trend， from 50.82% in 2012 to 41.29% in 2021. At the same time， the use rate of restricted and special antibiotics had also decreased， and the use rate of restricted and special antibiotics in patients without hospital infection was significantly lower than that in patients with hospital infection， and the microbial testing rate was also on the rise. The annual incidence rate of hospital infection was 0.69%‒1.92%， and the annual case-time prevalence rate was 0.79%‒2.17%. The annual average rate of the above two in 10 years was 1.18% and 1.34%， respectively. The results of the exponential smoothing model also showed that the utilization rate of antibiotics was decreasing and the incidence of nosocomial infection was stable. ConclusionLarge general hospitals took comprehensive management measures to strengthen the management of rational use of antibiotics， which led to a decline in the use rate of antibacterial drugs for inpatients and an increase in the rate of microbial examination. At the same time， the overall incidence of hospital infection was relatively stable， suggesting that the comprehensive management measures of antibacterial drugs in hospitals had achieved certain results. The current measures need to be optimized in the future to continuously improve the management level of rational use of antibacterial drugs.

Objective To understand the epidemiological characteristics of norovirus infectious diarrhea in Pudong New Area of Shanghai, and to provide reference for prevention and control of diarrhea caused by norovirus. Methods Epidemiological data and stool samples from diarrhea cases of 15 hospitals in 2015-2019 years were collected. The two subtypes of norovirus G I and G II were detected by RT-PCR and analyzed. Results A total of 9 397 diarrhea samples were collected in 2015-2019 years, and 1 938 positive norovirus samples were detected, with a positive rate of 20.62%. The majority of serotypes were GII (88.60%). Diarrhea caused by norovirus occurs all year round, with high incidence season in 2-3and 10-12 months every year. There was no significant difference in the positive rate of norovirus between different sexes（χ2=2.611，P=0.106）. The positive rate of the 15-64 year old group was higher than that of the 0-14 year old group and the 65 year old and above group（χ2=153.634，P<0.001）. The highest positive rate was for cadres /worker/ business services / teachers / medical staff / drivers. The positive rate of norovirus in diarrhea cases with vomiting was significantly higher than that in patients without vomiting. Conclusions Diarrhea caused by norovirus is related to season, age and occupation. Because there is no effective antiviral drugs and vaccine prevention, continuous monitoring should be carried out and targeted preventive measures should be carried out according to epidemiological characteristics.
