Primary Outcomes (End Points)
|
Before
Primary Outcome Measure:
1.number of targeted high cost scans ordered per visiting provider
[Time Frame: first 365 days after CDS is turned on for the treatment group]
targeted high cost scans are all magnetic resonance (MR) or computed tomography (CT) scans
Secondary Outcome Measures:
1. Number of targeted high cost scans ordered per visiting provider that ACR rates 1-3 ("usually not appropriate")
[Time Frame: first 365 days after CDS is turned on for the treatment group]
targeted high cost scans are all magnetic resonance (MR) or computed tomography (CT) scans
2. Number of non-targeted high cost scans (nuclear medicine) ordered per visiting provider
[Time Frame: first 365 days after CDS is turned on for the treatment group]
3. Number of low cost scans (e.g. x-ray and ultrasound) ordered per visiting provider
[Time Frame: first 365 days after CDS is turned on for the treatment group]

After
Primary Outcome Measure:
• Number of "non-advised" scans ordered per visiting provider
[Time Frame: first 365 days after CDS is turned on for the treatment group] [Safety Issue: No]
"non-advised" scans are (a) all magnetic resonance (MR) or computed tomography (CT) scans that ACR Select rates 1-3 ("usually not appropriate"), and (b) all MR or CT scans rated 4-6 ("may be appropriate") for which an alternative scan (MR, CT, or other modality) rated 7-9 ("usually appropriate") exists
Secondary Outcome Measures:
• Number of scans ordered per visiting provider that ACR Select rates 1-3 ("usually not appropriate")
[Time Frame: first 365 days after CDS is turned on for the treatment group] [Safety Issue: No]
includes magnetic resonance (MR) and computed tomography (CT) scans scored by ACR Select
