Abstract
The antimicrobial stewardship program (ASP) is intended to promote the use of appropriate antimicrobial agents in consideration of bacteria and infection sites which cause various infectious diseases. Infection control software can collect information in a short period of time. We report the results of effective antibiotic appropriate use support with the software. In the first year of the 2–year period from January 2013 to December 2014, there were 81 instances of pharmacist support of antimicrobial use by physicians, which increased by 3.4 times to 272 in the second year. The contents of support were often “De-escalation”, “Proposal of the end”, “Proposal of new antimicrobial agents or change in empiric therapy”. Consultation instances totalled 43 in the first year, but increased by 4.3 times to 186 in the second year. Antimicrobial use density of tazobactam/piperacillin in the second year (TAZ/PIPC) (AUD) was significantly reduced compared to the first year, and the resistance rate for TAZ/PIPC of Pseudomonas aeruginosa also decreased significantly. These results presumably indicate that the reduction in the AUD of the TAZ/PIPC is related to decreased resistance rates of P. aeruginosa. We found that pharmacists were able to efficiently gather data in a short period of time by utilizing the infection control software and positively participated in infectious disease therapy, resulting in correct antimicrobial use by physicians.
