What is surgical site infection surveillance? Why and how to conduct targeted surveillance for surgical site infections?

The Hospital Infection Surveillance Standards clearly require that targeted surveillance of surgical site infections should be carried out on all day surgery, elective surgery and emergency surgery patients. The hospital infection management department should summarise and analyse the situation in relation to the same period in history and the previous infection situation, identify problems in the monitoring, report to the hospital infection management committee, and provide feedback to the clinical departments on the monitoring results and make recommendations for improvement.

1. Terms and definitions
a. Hospital infection surveillance: long-term, systematic and continuous collection and analysis of the occurrence and distribution of hospital infection and its influencing factors in a certain group of people, and reporting and feedback of the monitoring results to the relevant departments and departments, so as to provide scientific basis for the prevention, control and management of hospital infection.
b. Comprehensive hospital-wide surveillance: Continuously monitor hospital infections and related risk factors for all inpatients and medical staff in all clinical departments.
c. Targeted surveillance: monitoring of hospital infections and their risk factors for high-risk groups and highly infected sites, such as monitoring of hospital infections in intensive care wards, monitoring of hospital infections in neonatal wards, monitoring of infections in surgical sites, monitoring of the clinical application of antimicrobials and monitoring of bacterial drug resistance.
Surgical site infection monitoring content surgical site infection monitoring its specific monitoring method in accordance with WS/T312-2009 ‘Hospital Infection Monitoring Specification’ Appendix C. The monitoring object is all elective and emergency surgery patients who are selected for monitoring surgery; the monitoring content includes general information of patients (hospital number, department, bed number), basic information of patients' surgery (name of surgery, date, surgeon), NNIS risk factor scores (ASA, length of surgery, classification of surgical incision), and information related to surgical site infections (date of infection, diagnosis, pathogens, etc.); the monitoring analysis Mainly includes the incidence rate of surgical site infections, the incidence rate of surgical infections with different risk indices, the exclusive rate of infection incidence among surgeons, and the adjusted incidence rate of infections. Timely feedback should be given after the monitoring to give feedback on the problems found in the monitoring, the results of the monitoring, the analyses of the monitoring, and the recommendations.
