Epidemiological distribution of multidrug-resistant bacterial infections in a psychiatric specialty hospital from 2021 to 2023
Objective To analyze the epidemiological characteristics of multidrug-resistant(MDR)bacterial infections in a psychiatric specialty hospital,providing evidence for effective infection control and prevention measures to reduce the likelihood of patients acquiring such infections during hospitalization.Methods Data on common clinical MDR bacterial infections in hospitalized patients from January 2021 to December 2023 were collected through the hospital infection management information monitoring system.The three-way distribution of MDR bacteria was analyzed,and sta-tistical analysis was performed using SPSS 25.0 software.Results A total of 917 cases of MDR bacterial infections were identified in the hospital's microbiology department.Of these,576 were male patients and 341 were female patients,with significant differences in gender distribution(x2=60.2,P＜0.01).The infection rate in male patients(2.56％)was significantly higher than that in female patients(1.62％)(x2=46.3,P＜0.01).The average age of male patients was(68.5±14.8)years,while the average age of female patients was(71.6±15.7)years,showing a statistically signifi-cant difference(P＜0.01).The distribution of MDR bacterial infections varied significantly across different hospital de-partments,with the highest detection rates observed in the ICU,general psychiatric wards,geriatric psychiatry,neurolo-gy,chronic psychiatric wards,and general psychiatric wards in decreasing order.There was also a statistically significant seasonal variation in the detection of MDR bacteria,with the first quarter showing the highest infection rates(x2=1 923,P＜0.01).Conclusion MDR bacterial infections are more prevalent in male patients compared to females,with male patients being younger on average.The distribution of these infections varies across different seasons,with a significant peak in the first quarter,indicating a seasonal pattern of occurrence.
