reducing empiric vancomycin use in pediatric suspected sepsis

Conditions: Sepsis; Sepsis Mrsa; Sepsis Bacteremia; Antimicrobial - Induced Nephropathy; Sepsis, Severe; Septic Shock; Septic Syndrome

Summary: the goal of this quasi-experimental interventional study is to determine the effectiveness of a multifaceted stewardship intervention in reducing overall vancomycin use in five tertiary care pediatric intensive care units (picu). there are two groups of subjects in this study: picu clinicians/sepsis stakeholders and patients admitted to one of the participating picus during the study period. the intervention will at a minimum include: * implementation of a clinical guideline indicating when vancomycin should and should not be used * unit-level feedback on overall vancomycin use within and across centers * clinician education.

vancomycin is among the most commonly prescribed antibiotics in united states children's hospitals, and inappropriate use of vancomycin is common. given the high prevalence of acute kidney injury associated with vancomycin of up to 25%, reducing vancomycin overuse is a key opportunity to reduce preventable patient harm. the primary objective of this study is to determine the effectiveness of a multifaceted stewardship intervention in reducing overall vancomycin use in five tertiary care picus. this intervention will be informed by baseline data surrounding vancomycin use and infections due to organisms requiring vancomycin therapy which will allow selective use of vancomycin, as well as a concurrent mixed methods process and formative evaluation to inform implementation of the intervention. during the baseline period, electronic health record (ehr) data will be used to retrospectively quantify unit-level vancomycin use over 24 months (measured as vancomycin days of therapy \[dot\]/1000 patient days), as well as the frequency of vancomycin use and prevalence of infections due to organisms requiring vancomycin therapy among patients with suspected and confirmed sepsis. during the post-intervention period, which will last approximately 24 months, a multifaceted stewardship intervention to reduce vancomycin use informed by these baseline data, including: * the creation of a consensus guideline for vancomycin use; * ad hoc education related to vancomycin overuse, and; * unit-level feedback on vancomycin prescribing. the feedback on vancomycin use will be provided to clinicians at each site, both within their site (to compare to past performance) and across sites (to compare local performance to the performance of other sites). this intervention will be locally adapted by the investigative team and sepsis stakeholders at each site. data from the ehr will be used to assess vancomycin use (dot/1000 patient days), as well as the secondary outcomes. investigators will perform semi-structured interviews and repeat surveys 9 months after the implementation of the intervention. this mixed-methods process and formative evaluation will help investigators understand which elements of implementation were successful and which were not.
