Antibiotics are prescribed as per the Antibiotic Therapeutic Guidelines (eTG). Approval is accessed via IDEA3s or duty intensivist in ICU. Requests by treating teams to continue prophylactic antibiotics for more than 24 hours should be referred to the duty intensivist. For complex patients, advise can be sought from the Infectious Diseases physician or registrar at Austin Health. There is an ID consult round at 2pm each Monday with Dr Andrew Mahoney. Approval numbers for antibiotics prescribed on the wards are provided by Dr Andrew Mahoney in business hours, and the Austin Health ID registrar on call when after hours.
