Low value preoperative testing does not improve patient outcomes or reduce adverse events. Low value preoperative testing costs patients and healthcare systems without benefit. In a previous study, the investigators identified the systems-level and individual-level drivers of low value preoperative testing. In this study, the investigators will use these drivers of low value testing to design and implement a bundled intervention to reduce low value preoperative testing in Alberta, Canada. The investigators will measure the impact of this intervention on the number of low value tests, adverse events (ICU admissions, length of stay, 30-day readmissions), and patient costs. The investigators will also interview healthcare providers on their experiences with the intervention.
