Objective  To collect the data of nosocomial infection surveillance in secondary and tertiary medical institutions in Jiangsu Province and conduct comparative analysis among different regions to find out the gaps and provide basis for targeted continuous improvement. Methods Combined with the requirements of grade hospital evaluation and high-quality development of public hospitals, the data of nosocomial infection incidence in medical institutions of Jiangsu Province in the first quarter of 2023 were collected by autonomous reporting and information capture, and the province was divided into three regions according to location: South Jiangsu, Central Jiangsu and North Jiangsu for analysis, so as to evaluate the regional level. Results  A total of 109 medical institutions were included, including 78 tertiary hospitals and 31 secondary hospitals. The overall incidence rate of nosocomial infection was 0.81% (0.90%). The incidence of central line-associated bloodstream infection (CLABSI), ventilator-associated pneumonia (VAP) and catheter-associated urinarytract infection (CAUTI) were 0.113‰, 1.553‰ and 0.424‰, respectively. The proportion of prophylactic drugs in Class Ⅰ incision and the incidence of surgical site infection in Class Ⅰ incision were 17.72% and 0.16%, respectively. In the above infection indicators, the incidences of CLABSI and VAP were higher in Central Jiangsu, while the other indicators were higher in South Jiangsu than in Central Jiangsu than in North Jiangsu. The utilization rate of antibiotics and the detection rate of pathogens in inpatients were 41.07% and 41.50%, respectively. Among South, North, and Central Jiangsu, the utilization rate of antibiotics was 41.83%, 41.51%, and 39.51%, respectively (χ²=446.789, P<0.001), and the detection rate of pathogens was 46.09%, 40.94%, and 35.09%, respectively (χ²=3036.865, P<0.001). In the detection rate of drug-resistant bacteria infection, the top 3 were carbapenem-resistant Acinetobacter baumannii (0.067%), carbapenem-resistant Klebsiella pneumoniae (0.031%) and methicillin-resistant Staphylococcus aureus (0.029%). Among them, the infection rate of drug-resistant bacteria in South Jiangsu was significantly higher than that in the other two regions. The detection rates of carbapenem-resistant Acinetobacter baumannii and methicillin-resistant Staphylococcus aureus were close to each other (83.77% vs. 53.91%), while the detection rates of carbapenem-resistant Escherichia coli (χ²=95.619, P<0.001), carbapenem-resistant Klebsiella pneumoniae (χ²=520.855, P<0.001) and carbapenem-resistant Pseudomonas aeruginosa (χ²=191.918, P<0.001) in South Jiangsu were significantly higher than those in Central and North Jiangsu. Conclusions  There are significant differences in nosocomial infection surveillance data of medical institutions in different regions of Jiangsu Province. It is emphasized that targeted quality control feedback, supervision and rectification should be carried out while hospital infection monitoring.
