The long-term effect of policies restricting contact between residents and pharmaceutical company representatives (PCRs) during internal medicine training is unknown. The McMaster University Department of Medicine in Hamilton, Ontario, implemented a policy restricting PCR contact with trainees in 1992, whereas the Department of Medicine at the University of Toronto, Toronto, Ontario, has no such policy. ⋯ Policies restricting PCR access to internal medicine trainees and the amount of contact during residency appear to affect future attitudes and behavior of physicians.

High levels of variation and inefficiency exist in current clinical practice regarding use of cervical spine (C-spine) radiography in alert and stable trauma patients. ⋯ We have derived the Canadian C-Spine Rule, a highly sensitive decision rule for use of C-spine radiography in alert and stable trauma patients. If prospectively validated in other cohorts, this rule has the potential to significantly reduce practice variation and inefficiency in ED use of C-spine radiography.

Randomized Controlled Trial Multicenter Study Clinical Trial
Caring for the critically ill patient. High-dose antithrombin III in severe sepsis: a randomized controlled trial.
Activation of the coagulation system and depletion of endogenous anticoagulants are frequently found in patients with severe sepsis and septic shock. Diffuse microthrombus formation may induce organ dysfunction and lead to excess mortality in septic shock. Antithrombin III may provide protection from multiorgan failure and improve survival in severely ill patients. ⋯ High-dose antithrombin III therapy had no effect on 28-day all-cause mortality in adult patients with severe sepsis and septic shock when administered within 6 hours after the onset. High-dose antithrombin III was associated with an increased risk of hemorrhage when administered with heparin. There was some evidence to suggest a treatment benefit of antithrombin III in the subgroup of patients not receiving concomitant heparin.
