Questions:
Question #1: How do stewardship and microbiology work together to impact patient care?
Question #2: What are some examples of evidence- based initiatives that involve a partnership between microbiology and stewardship that can improve antibiotic use and antimicrobial resistance testing on a larger scale?
Question #3: Describe some examples of novel interventions or innovations implemented at your program which have helped improve antibiotic use.
Question #4: What are some national challenges faced by microbiology labs, and how can stewardship programs advocate for the needs of microbiology labs?
Question #5: In what additional ways would you like to see clinical microbiology and antimicrobial stewardship teams working together in the future?
