Documented follow-up = B0 + B1 (arm) + B2 (Elixhauser score) + B3 (LOS) + B4 (physician-type) + B5 (physician years employed) + B6 (arm*characteristic)
Italic values represent the denominator and numerator for each outcome measure
*Adjusted for clinical service; test type (pathology vs. other); physician type (hospitalist), years employed (≤ 5 yrs); patient Elixhauser score (≤ 5), median LOS (≥ 4 days). Clustered by attending
aIn sub-group analyses for documented acknowledgment, percentages, ORs, and p values calculated were similar across all characteristics and was statistically significant for Elixhauser (I vs. C: 64.0 vs. 50.0%; adjusted OR 1.84 [0.80, 4.2]; p = 0.04)
