tier p progression) g ) Training and educational availability 8 ProCE, Inc. www.ProCE.com 4 Antimicrobial Stewardship CHS Pharmacy Education Series CHSPSC ASP Initiative Project Goals • Implement new or enhance existing antimicrobial stewardship programs consistent with CDC Core Elements at Community Health Systems (CHS)-affiliated facilities • Improve antimicrobial use • Reduce antimicrobial drug g expenditure p from inappropriate pp p and/or unnecessary antimicrobial use • Increase education and knowledge surrounding antimicrobial stewardship 9 CHSPSC ASP Initiative Project Objectives • Increase the number of sites with core antimicrobial stewardship elements • Increase the number of sites with enhanced antimicrobial stewardship elements • Increase pharmacist documentation of antimicrobial stewardship activities • Increase and expand use of decision support tools • Decrease measures of antimicrobial use • Decrease antimicrobial expenditure • Increase the number of pharmacists with antimicrobial stewardship certification • Conduct ongoing corporate antimicrobial site education and communication • Increase the number of pharmacist competencies pertaining to infectious diseases and antimicrobial stewardship • Conduct baseline competency assessment for pharmacists in antimicrobial stewardship 10 ProCE, Inc. www.ProCE.com 5 Antimicrobial Stewardship CHS
