Antimicrobial Stewardship

CDC Antibiotic Awareness Week 2021 logo


  • More than half of hospitalized patients have been shown to receive unsupported antibiotics [i]. This includes: 
    • 79% of patients with community-acquired pneumonia (due to excessive duration)
    • 77% of patients with urinary tract infection (due to undocumented infection signs/symptoms)
  • Physicians, nurses, and pharmacy and laboratory staff can work together to improve and optimize antimicrobial use (AU) through effective antimicrobial stewardship (AS) programs (ASP). 
  • ASP interventions have been demonstrated to improve patient outcomes and reduce adverse consequences, including combatting antimicrobial resistance (AR) and mitigating Clostridioides difficile infections.
  • Promote AS in your facility by participating in the following CDPH activities:
CDPH Honor Roll logoCDPH ASP Honor Roll: More than one third (135 of 399) California hospital ASP are Honor Roll members. Apply for Bronze, Silver, or Gold level designation to recognize your facility’s ASP.


Circle of locking armsCalifornia AS Collaborative Network (ASCN): Share ideas and knowledge, and collaborate on AS topics and projects with peers.


CDC NHSN AU Reporting logo National Healthcare Safety Network (NHSN) AU and AR Reporting: One third of hospitals are reporting AU data, and one sixth are reporting AR data to NHSN.  Use the CDPH toolkit to get started with NHSN AU and/or AR data reporting.


CDC Be Antibiotic Proud logo CDC's Be Antibiotics Aware Toolkit: Get involved and promote antibiotic awarenessin your communities using CDC’s resources and tools.
