Based on information on pathogenic microorganisms from the microbiology laboratory, the Department conducts activities such as isolation status surveys with periodic reports for other departments, and guidance on the proper use of mupirocin, vancomycin, and teicoplanin. The Department also prepares antibiograms twice a year to provide drug sensitivity information in the hospital.

ICT rounds are held every Thursday to gather information onsite. If issues regarding in-hospital infection control or treatment of infectious diseases arise, the Department will consult with physicians and nurses to address the problem.

In the event of an outbreak, training for new staff members, or at the request of patient wards, the Department provides demonstration and instruction on how to wash hands.

The Department requires forms to be submitted upon using carbapenems and anti-MRSA agents. By doing this, AST (Antimicrobial Stewardship Team) will be able to monitor their daily usage status. For long-term or inappropriate use of antimicrobial agents, the Department will discuss with attending physicians to better promote appropriate use. The Department also works together with the Department of Pharmacy to check TDM (therapeutic drug monitoring) status.　

When a nosocomial infection outbreak is suspected, or when multiple multidrug-resistant bacterial colonization cases occur, isolated strains go through genetically analyses to determine and investigate the source of infection and to plan countermeasures.

Wards with frequent nosocomial infection outbreaks are surveyed as needed upon consultation with staffs in the ward.

hen consulted by staffs in wards, or when atypical bacteria are isolated and identified, the Department, together with the Department of Infectious Diseases, will provide information on treatment and countermeasures for the ward staff in charge.

The Department is responsible for handling needlestick/sharps injuries and blood and body fluid exposure of healthcare professionals. In addition, the circumstances that led to these incidents are analyzed by collecting information and compiling a report using the EPINet format.
