Flow chart depicting 'pre-authorisation and feedback' and 'prospective audit and feedback' Chung GW et al. Virulence 2013;4(2):151–157

One way to organise the different stewardship strategies into a conceptual framework is to place them into four categories based on two factors:

1) Do they occur before prescribing or after prescribing?

2) Do they require an active or passive interaction with prescribers?

A hybrid approach of active and passive, before and after prescribing methods is likely to have the greatest impact. Please see below for summaries of the most widely used AMS interventions and highlights some pros and cons to each strategy.

Institution-specific treatment guidelines (e.g. skin and soft tissue infections, abdominal infections, pneumonia, surgical prophylaxis)

Institutional guidelines that tailor recommendations from national guidelines to local resistance data, patient population, and formulary.

Classification: Passive pre-prescription

Click for Pro/Cons

Provide Education

Education provided in large-group format or through written AMS and hospital resources (e.g. policy, newsletters, etc.) to expand clinical providers’ knowledge about antibiotics and infectious diseases

Classification: Passive pre- or post-prescription

Click for Pro/Cons

Pre-authorization

Requirement for providers to seek AMS program or infectious diseases review and approval of antibiotic therapy prior to initiation.

Classification: Active – pre-prescription

Click for Pro/Cons

Prospective Audit and Feedback

AMS program review of patients on select antibiotics after initiation of therapy with directed feedback to the provider.

Classification: Active post prescription

Click for Pro/Cons

Automatic Stop Orders

The use of an antibiotic is permitted for a defined period of time and then requires approval for continuation.

Classification: Active post prescription

Click for Pro/Cons

Cascading or Tiered Antibiotic Susceptibility Reports

A collaborative effort with microbiology to select specific susceptibility tests to include in clinical culture reports while censoring others.

Classification: Passive post prescription

Click for Pro/Cons

Peer Comparison Data Feedback to Prescriber

Feedback of antibiotic use and/or appropriateness of prescribing data to the prescriber to allow comparison to other prescribers.
