Brief summary

Staphylococcus aureus bacteremia (SAB) is associated with high morbidity and mortality rates with an incidence disproportionately higher in vulnerable populations. Management according to evidence-based care parameters, in particular Infectious Diseases (ID) consultation, is associated with improved mortality. SAB management is suboptimal in Alberta compared to other jurisdictions. An Alberta-based pilot study confirmed that timely recommendations to optimize SAB care, including ID consultation, was associated with improved adherence to all evidence-based quality-of-care indicators. Leveraging this pilot work, the investigators aim to implement OPTIMUS-SAB, an enhanced model of the pilot, to optimize and standardize SAB management across Alberta. The implementation study will be a zone-based acute care site stepped wedge design. OPTIMUS-SAB will consist of a centralized SAB care team whom will receive automated notification of all blood cultures positive for S. aureus allowing them to review the patient's medical chart and make preliminary management recommendations according to an evidence-based care bundle. The investigators will evaluate adherence to evidence-based SAB quality-of-care indicators before and after OPTIMUS-SAB implementation and expect this to improve with a resultant reduction in duration of bacteremia, length of stay, readmission rates, and mortality. In turn, this will translate into cost savings for the health care system.

Design outcomes

Primary

MeasureTime frameDescription
Adherence to quality-of-care indicatorsWithin 90 daysDefined as: 1. ID involvement and time to ID involvement, defined by the presence of an ID consult note and/or recommendations in the chart. 2. Repeat blood cultures, to document clearance of bacteremia, within 72 hours from the last positive blood culture. 3. Guideline-concordant empiric antibiotic administered and time to receipt. 4. Guideline concordant definitive antibiotic administered and time to receipt. 5. Therapeutic drug monitoring of patents treatments with vancomycin. 6. Appropriate dose adjustment of antimicrobials based on renal function according to local guidelines. 7. Echocardiogram (transthoracic or transesophageal) performed within 72 hours of diagnosis. 8. Source control achieved. 9. Appropriate duration of antibiotic therapy ordered and delivered.

Implementation evaluation3 yearsUser experience and feedback from patients and providers will be collected at the start and end of each active implementation phase. This information will be paired with assessments of barriers, facilitators, and contextual factors informed by the Consolidated Framework for Implementation Research (CFIR) and Normalization Process Theory during the pre-implementation phase and at the end of active implementation.
