Brief Summary

The purpose of this study is to reduce the exposure of broad-spectrum antimicrobials by optimizing the rapid detection of CAP pathogens and improving rates of de-escalation following negative cultures. To accomplish this, we will perform a 3-year, pragmatic, multicenter 2 X 2 factorial cluster randomized controlled trial with four arms: a) rapid diagnostic testing b) pharmacist-led de-escalation c) rapid diagnostic testing + pharmacist-led de-escalation and d) usual care

Detailed Description

Community-acquired pneumonia (CAP) is a leading cause of hospitalization and inpatient antimicrobial use in the United States. However, diagnostic uncertainty at the time of initial treatment and following negative cultures is associated with prolonged exposure to broad-spectrum antimicrobials. We propose a large multicenter cluster randomized controlled trial to test two approaches to reducing the use of broad-spectrum antibiotics in adult patients with CAP a) routine use of rapid diagnostic testing at the time of admission and b) pharmacist -led de-escalation after 48 hours for clinically stable patients with negative cultures.

When a patient is admitted with a diagnosis of pneumonia, it will trigger the admission order set and if the physician is in a hospital randomized to the rapid diagnostic testing arm, a CDSS-based alert will be generated in real time, and the form will append orders for viral and UAT testing. For physicians at a hospital randomized to the control condition, ordering will proceed as usual (standard-of-care). A second CDSS algorithm will identify study patients who have negative culture results (blood and/or sputum) for greater than 48 hours and generate a list for the antimicrobial stewardship pharmacist, who will be a member of the study team. The alerts will be audited by the clinical pharmacist daily on weekdays at a centralized location. In clinically stable patients from hospitals randomized to the de-escalation arm, the pharmacist will communicate their recommendations for de-escalation to the clinical providers via a phone call, Epic chat, or page. The primary outcome will be the duration of exposure to broad-spectrum antimicrobial therapy defined by the number of days of antibiotic therapy from initiation to discontinuation. Secondary outcomes will include detection of influenza/RSV, de-escalation and re-escalation to broad-spectrum antibiotics after de-escalation, total antibiotic duration, in-hospital mortality, ICU transfer after admission, healthcare-associated CDI and acute kidney injury after 48 hours.

Rapid diagnostic testing (RDT)Rapid Diagnostic TestingRapid diagnostic testing: Eligible patients at hospitals randomized to this arm will undergo testing for viral pathogens (from November-April) and pneumococcal UAT testing. If the patient is not being admitted to the ICU, and the patient has an admitting diagnosis of pneumonia, the form will append orders for viral testing and UAT testing to providers in hospitals randomized to receive it.

The alerts will be audited by the pharmacist daily on weekdays at a centralized location. The pharmacist will attempt to determine whether each patient is clinically stable. If the patient appears stable, the pharmacist will communicate their recommendations for de-escalation to the clinical providers via a phone call or page.

The alerts will be audited by the pharmacist daily on weekdays at a centralized location. The pharmacist will attempt to determine whether each patient is clinically stable. The validated measures of clinical stability in patients with CAP are a) resolved vital sign abnormalities b) normal mental status c) ability to eat. If the patient appears stable, the pharmacist will communicate their recommendations for de-escalation to the clinical providers via a phone call or page.
