Abstract: Objective: To understand the characteristics of hospital acquired infections in inpatients of the Oral and Maxillofacial Surgery Department and propose appropriate prevention and control strategies. Methods: The data on hospital acquired infections, etiological test results of 49,815 inpatients who underwent surgery in the Oral and Maxillofacial Surgery Ward of Peking University School and Hospital of Stomatology from January 2018 to December 2024, as well as the targeted surveillance data of pulmonary infections in 2024 were reviewed. The characteristics of hospital acquired infections in inpatients of the Oral and Maxillofacial Surgery Department and the control countermeasures were analyzed. Results: The common types of hospital acquired infections in inpatients of the Oral and Maxillofacial Surgery Department were surgical site infections and pulmonary infections. The common pathogens of hospital acquired infections were Pseudomonas aeruginosa, Klebsiella pneumoniae, and Streptococcus viridans. The overall detection rate of multidrug-resistant bacteria was 13.45%, and the detection rate of drug-resistant Escherichia coli was the highest. Conclusions: Effective hospital infection control relies on actively conducting hospital infection monitoring, revealing infection characteristics and risks, and providing a foundation for achieving infection control goals.
