Brief Summary

One in five hospitalized patients is prescribed an antimicrobial at the time of discharge, and a large proportion of these post-discharge antimicrobials are unnecessary. The investigators will evaluate a novel method for reviewing post-discharge antimicrobial prescriptions in real-time with the goal of improving antimicrobial selection and duration.

Detailed Description

Antimicrobial stewardship programs (ASPs) work to improve antibiotic prescribing within hospitals. ASPs often restrict their activities to inpatient antimicrobial-prescribing. However, at least 40% of all antimicrobial exposure associated with an acute-care hospital stay is prescribed at the time of hospital discharge (i.e., post-discharge). Post-discharge antimicrobials mediate clinical outcomes after discharge and may facilitate the spread of antimicrobial resistance.

Several studies have shown that post-discharge antimicrobial use is often inappropriate. For example, using national VA data, the investigators found that 61% of fluoroquinolone treatment days were prescribed at hospital discharge; manual chart reviews at 9 hospitals found that 40% of these post-discharge fluoroquinolone prescriptions were either unnecessary or sub-optimal. Other studies have found that 53-79% of all post-discharge antimicrobials are either unnecessary or sub-optimal.

Post-discharge antimicrobials are an important target for antimicrobial stewardship. However, inpatient stewardship metrics do not capture post-discharge antimicrobials and ASPs frequently do not evaluate these prescriptions. A 2016 VA survey found that less than 50% of hospitals routinely reviewed targeted antimicrobials at discharge. According to a 2016 survey in Michigan, only 17% of 48 hospitals had a process for reviewing outpatient antimicrobial orders at discharge.

It is unclear how inpatient stewardship resources can be effectively leveraged to improve post-discharge antimicrobial use. If the goal is to improve post-discharge antimicrobial use, a potentially effective strategy may be an audit-and-feedback process focused solely on prescriptions for patients who will soon be discharged. In this trial, the investigators will evaluate the feasibility and effectiveness of such a process.

Prospective audit-and-feedback at dischargeProspective audit-and-feedbackWhen hospitals are in the intervention arm, they will perform the audit-and-feedback process focused on patients receiving antimicrobials who have an anticipated discharge.
Primary Outcome Measures
NameTimeMethod
Post-discharge antibiotic length of therapyEvery 2-week-period through study completion (48 weeks total)

The primary outcome will be post-discharge antimicrobial length of therapy (LOT) per 100 admissions. The investigators will calculate this by adding post-discharge LOT across all patients on the participating services and dividing by the number of patient-admissions discharged from those services during the study period.

Secondary Outcome Measures
NameTimeMethod
Inpatient antibiotic length of therapyEvery two-week period through study completion (48 weeks total)

Inpatient antibiotic LOT will be calculated by adding inpatient LOT across all patients on the participating services and dividing by the number of patient-admissions discharged from those services during the study period.

Percentage of participants with hospital readmission30 days from discharge

Hospital readmissions reflect the need for (re) admission to an acute-care bed at a participating facility for any indication within 30 days of the patient's discharge.
