Antimicrobial Stewardship

Question 1

Factors influencing AMR?

Answer 1

• Widespread antibiotic use encouraging selective pressure (i.e surviving
  bacteria develop resistance).
• Antibiotic use by medical professions (including dentists), veterinary
  practices, farming.
• Patients surviving longer with more medical conditions and hospital contact.
• More invasive procedures and prosthetic devices e.g. dialysis patients.
• In UK increased bed pressure encourages spread of resistant organisms.

Question 2

SELECTIVE PRESSURE?

Answer 2

wipe out other microbes and allow the resistant bacteria to dominate and multiply
