Effect of Health Care System Factors on Test Ordering

The influence of resident seniority on supervised practice in the emergency department

“…Some previous studies discussed the impact of residents on ED diagnostic tool before, [ 15 , 16 ] but most were localized, single-hospital trials. One recent multicenter study by Pitts et al [ 6 ] reported increased diagnostic tool use among supervised visits.…”

Serum Magnesium Levels in Pediatric Inpatients: A Study in Laboratory Overuse

“…26,27 Our study identifi ed an example of laboratory overuse that lends itself to efforts for quality improvement, such as using audits to change existing behaviors. 28 Administrative solutions have also been used successfully in decreasing laboratory overutilization.…”

Emergency Department Resource Use by Supervised Residents vs Attending Physicians Alone

We confirmed consistently higher use of several ED resources among supervised visits, even after adjustment for several other possible determinants of resource use that were available in the survey.…”
