BALANCE on the Wards: A Pilot RCT — BALANCE-Wards  

Bacteremia Clinical Trial

Official title: Bacteremia Antibiotic Length Actually Needed for Clinical Effectiveness- BALANCE on the Wards: A Pilot RCT

Status Completed

Clinical Trial Summary

The burden of bloodstream infections is large and increasing over time. Antibiotic overuse continues to drive increased rates of antimicrobial-resistant pathogens across Canada. However, prospective audits have revealed that 30-50% of antibiotic utilization is unnecessary or inappropriate. If shorter duration therapy is as effective as longer duration therapy for these infections, antimicrobial consumption would be decreased. A pilot trial (approved by the Sunnybrook Research Ethics Board), is underway in critically ill patients at 17 Canadian ICUs. Investigators have successfully demonstrated feasibility with respect to protocol adherence and recruitment rates in the ICU. Investigators now aim to conduct a similar pilot RCT among non-ICU patients admitted to hospital wards with bloodstream infections to determine feasibility and protocol adherence of the same trial protocol.

Clinical Trial Description

Bloodstream infections are a common and serious problem, and are associated with increased morbidity and mortality. At the same time, antibiotic overuse is also a common and serious problem, in that 30-50% of antibiotic use is unnecessary or inappropriate, and results in avoidable drug side effects such as kidney failure, Clostridium difficile infection, increased costs, and spiraling antibiotic resistance rates. The greatest contributor to antibiotic overuse is excessive durations of treatment.

Extensive research has demonstrated that shorter duration antibiotic treatment (less or equal to 7 days) is as effective as longer duration treatment for a variety of infectious diseases, but this question has not been directly studied in the setting of bloodstream infection. Our team's systematic review of the medical literature, national survey of Canadian infectious diseases and critical care physicians, and multicentre retrospective study all support the need for a randomized controlled trial comparing shorter (7 days) versus longer (14 days) antibiotic therapy for bloodstream infections.

Prior to performing the main trial, our pilot RCT in critically ill patients is near-completion.

In order to increase the generalizability to non-critically ill patients, Investigators want to conduct a similar pilot RCT in non-critically ill patients (BALANCE on the Wards) to establish the feasibility of the research design, and to optimize the definitive trial.

Investigators will conduct a randomized concealed allocation trial of shorter duration (7 days) versus longer duration (14 days) antibiotic treatment for patients with bloodstream infections across all non-ICU hospital wards in Sunnybrook Hospital (BALANCE on the Wards). Our ongoing BALANCE pilot RCT in ICU is approved by the Sunnybrook REB (PIN: 187-2014). The BALANCE on Wards pilot trial will use the same protocol, informed consent form and the case report forms that are approved by the Sunnybrook REB with minimal changes to make it ward specific. If the investigators are able to achieve the primary outcome of this trial in Sunnybrook hospital, the main BALANCE trial will potentially involve enrolment of non-ICU patients at all (or a subset of) participating sites.

If eligibility criteria and study procedures are substantially unchanged, results of the both the pilot BALANCE RCTs will be rolled into the dataset for the main BALANCE RCT. ;
