Groups2
Group 2 names the comparator: control.
| Group | Title | Description | With the outcome | Analysed | ClinicalTrials.gov code |
|---|---|---|---|---|---|
| Group 1 | Intervention | Patient charts reviewed after intervention initiation for guideline-concordant prostate cancer imaging.~The intervention is comprised of three components: 1) Clinical Order Check, 2) Academic Detailing, and 3) Audit and Feedback.~Clinical Order Check: A Clinical Order Check is an evidence-based, systems-level method to affect significant behavior change. It addresses the intervention functions of education, enablement and incentivization which are effective methods to change behaviors driven by beliefs about capabilities, knowledge, social influences, beliefs about consequences, and environmental context and resources.~Academic Detailing: Academic detailing is an individual and facility-level intervention consistently shown to improve provider behavior. This strategy addresses the intervention functions of persuasion, coercion, modeling, and education which are effective methods for affecting behaviors driven by beliefs about capabilities, knowledge, social influences, beliefs about consequences, and environmental context and resources.~Audit and Feedback: Audit and feedback is an effective, individual-level intervention for changing healthcare provider behavior. Audit and feedback addresses the intervention functions of education, persuasion and incentivization, all of which are important for addressing beliefs about capabilities and consequences, knowledge, and social influence. | 109 | 734 | OG001 |
| Group 2 | Control | No intervention. Patient charts reviewed prior to intervention initiation in stepped wedge design. | 141 | 690 | OG000 |
