LG16: Antimicrobials
Clinical sciences
Advanced Trainees will describe the principles of the foundational sciences.
Eligibility considerations
Advanced Trainees will assess patients’ current conditions and plan the next steps.
Undertaking therapy
Advanced Trainees will monitor the progress of patients during the therapy.
Post therapy
Advanced Trainees will know how to monitor and manage patients post-therapy.
Important specific issues
Advanced Trainees will identify important specialty-specific issues and the impact of these on diagnosis, management and outcomes.
