Methods: Introduction of the Acute Upper GI Bleeds proforma during continued use of "consult forms" gave a proforma group (P) and a "consult form" group (C). The quality of referral information was prospectively assessed. Five critical fields made up the primary outcome measure: Hb, INR, platelets, heart rate and blood pressure. Sample size calculation estimated that 73 referrals would be required to detect a 33% difference between groups P and C for the presence of all 5 of these outcome measures with p= 0.05 and beta = 0.8.
