Recommendations for laboratory tests and hematology consultation across surveyed specialties: first and second presentations. The percentages of physicians in each specialty who would have ordered specific hematologic laboratory tests after each of the case patient’s presentations (A and C) and the percentages who would have ordered repeat coagulation studies and consulted a hematologist after reviewing each set of laboratory results (B and D) are shown. Critical care specialists began their case presentation with the second presentation and were given a different set of vital signs from the other specialties (see Figure 1). Rheumatologists were presented with only the initial patient presentation and subsequent laboratory findings, which included PT and aPTT values that were different from those provided to the other specialties (see Figure 1). In addition, the case patient presented to rheumatologists was evaluated and managed on an outpatient basis. Hematologists were not queried about consulting a hematologist in response to hematologic laboratory results.
