Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
In hospital patients with medical emergency team (MET) calls for suspected sepsis, antimicrobial therapy is currently managed by the admitting, or home, team. Complex cases may be referred to specialist Infectious Diseases (ID) clinicians on request by the treating team. The antimicrobial stewardship (AMS) team (ID physician and pharmacist) currently conduct a post prescription review of a limited patient group, after the prescription of restricted antimicrobial agents or a positive blood culture result. The former group is primarily identified by clinical pharmacists who request review of their patients, but the AMS team also reviews patients on broad spectrum antimicrobial agents identified by other means. This AMS review is a focused review of medical records, pathology results and clinical notes, but does not include a clinical or physical review of the patient. The AMS team then make recommendations about antimicrobial therapy to the treating team.
Currently, patients with MET calls for suspected sepsis are not routinely seen by the AMS team, despite the use of broad-spectrum antimicrobial agents. Many of these patients are not flagged to the AMS team via the current practice, or referral via current notification mechanisms is often delayed.
The intervention will be ongoing standard care as above, as well as an expert ID AMS review at 48 hours after a MET call for suspected sepsis.

Treatment: Drugs
Comparator / control treatment
This study will enroll patients with MET calls for suspected sepsis who would otherwise not be seen by an AMS team. Control patients will continue to receive standard care and management by the treating team as above, which does not currently involve an AMS review for this patient group.

Control patients who are later referred for an AMS review by the treating team will be reviewed as standard care, but will be excluded for the purpose of this study.

Patient allocation will be concealed by sequentially numbered, opaque envelopes sealed by an independent research assistant.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Patient allocation will be determined by computer-generated randomisation.

Statistical methods / analysis
Sample size calculation:
To detect a difference in antimicrobial appropriateness at 72 hours between 50% in the control group and 80% in the intervention group with an a of 0.05 and 80% power, 45 patients are required in each arm of the study. Due to the limited size of the pilot study used to guide sample size calculations, as well as to allow for patient loss, this number will be inflated to enrol approximately 60 patients in each arm.

Statistical analysis:
Descriptive statistics will be derived. Demographic characteristics and primary and secondary outcomes will be compared between the control group and intervention group participants. Dichotomous outcome measurements will be compared using a chi2 or Fisher exact test. Continuous variables will require a t test or a Mann-Whitney test as appropriate. A p value < 0.05 will be considered to be statistically significant.

Summary
Brief summary
Background: Sepsis is one of the leading causes of death in hospital patients. The early administration of broad spectrum antimicrobials improves survival in sepsis. However, the use of these antimicrobials must be balanced with their unintended consequences, such as the development of antimicrobial resistance and adverse effects. Many patients receive prolonged courses of inappropriate antimicrobials in suspected sepsis. The established antimicrobial stewardship (AMS) team currently do a post-­prescription review of restricted antimicrobials and positive blood cultures. They do not routinely review treatment in sepsis, however they may have a role to promote the optimal use of antimicrobials in this setting.
Aim: To determine the impact of AMS intervention in patients with medical emergency team (MET) calls for suspected sepsis
Hypothesis: AMS intervention will improve appropriateness of antimicrobial therapy in suspected sepsis
Participants: Patients with MET calls for suspected sepsis
Method: Randomised controlled trial
Control: Standard care (antimicrobials managed by the home team)
Intervention: Standard care PLUS AMS review 48 hours post MET call
Outcomes: Appropriateness of antimicrobial therapy at 72 hours post MET call
