The goal of this stepped-wedge cluster randomized trial is to assess the impact of a laboratory test overuse intervention bundle on laboratory test utilization in 6 health authorities (16 hospitals) in British Columbia. The main question it aims to answer is if the intervention bundle, inclusive of healthcare provider and patient engagement tools, can be effectively implemented for hospitalized medical inpatients in 16 hospitals across BC and reduce laboratory test over-use. Researchers will compare hospital clusters that receive the intervention at different (sequential) time points to see if there are significant changes in the measured outcomes after the intervention.
Patients: The study will include all adult general medical patients that are admitted to the selected hospital during the study period under general internal medicine or family medicine (hospitalist) provider groups.
Attending Physicians: All physicians who provide patient care in the general internal medicine or family medicine (hospitalist) provider groups in selected hospitals
Learners and allied health staff (Medical Students/Resident physicians/Clinical Assistants/ Nurse Practitioners, etc.): All those who help take care of patients and can order labs during the study period in the under general internal medicine or family medicine (hospitalist) provider groups in selected hospitals The date range for both groups will extend from May 2024 until study completion in October 2026.
Patients: all patients in specialized medical units (e.g., coronary care, dialysis units, bone marrow transplants units etc.), in critical care, pediatric, obstetrical, surgical, and psychiatric units.
