This video is a recording of the live webinar hosted by He Ako Hiringa on 22 November 2022. Dr Sharon Gardiner and associate professor Matire Harwood highlight the importance of antimicrobial stewardship in New Zealand.

In this video, Dr Gardiner discusses how:

  • 1.3 million deaths were attributable to antimicrobial resistance (AMR) globally in 2019
  • Aotearoa New Zealand has high antimicrobial use, and much is inappropriate
  • although relatively insulated from AMR to date, we are now at a tipping point
  • we can slow AMR by using antimicrobials only when needed, and using them well
  • a collective, equitable response is needed to ensure we keep antimicrobials working.

Dr Harwood discusses:

  • recommendations from Kotahitanga: Uniting Aotearoa against infectious disease and antimicrobial resistance.
