Effect analysis of multi-department cooperation in improving etiological submission rates before antibiotic treatment

Increased bacterial drug resistance has become a serious global public health problem. The application of antibiotics involves various clinical departments, and the rational application of antibiotics is the key to improving their efficacy. To provide a basis for further improving the etiological submission rate and standardizing the rational use of antibiotics, this article discusses the intervention effect of multi-department cooperation in improving the etiological submission rate before antibiotic treatment. A total of 87 607 patients were divided into a control group (n = 45 890) and an intervention group (n = 41 717) according to whether multi-department cooperation management was implemented. The intervention group involved the patients hospitalized from August to December 2021, while the control group involved the patients hospitalized from August to December 2020. The submission rates of the two groups; the rates before antibiotic treatment at the unrestricted use level, the restricted use level, and the special use level in departments; and the timing of submission were compared and analysed. The overall differences in the etiological submission rates before antibiotic treatment at the unrestricted use level (20.70% vs 55.98%), the restricted use level (38.23% vs 66.58%), and the special use level (84.92% vs 93.14%) were statistically significant before and after intervention (P < .05). At a more specific level, the etiological submission rates of different departments before antibiotic treatment at the unrestricted use level, the restricted use level, and the special use level were improved, but the special activities of multi-department cooperation management did not improve the submission timing significantly. Multi-department cooperation can effectively improve the etiological submission rates before antimicrobial treatment, but it is necessary to improve measures for specific departments to improve long-term management and incentive and restraint mechanisms.
