Abstract

STUDY OBJECTIVES: To estimate periprocedural bleeding risk before elective percutaneous coronary intervention (PCI) by using a point-of-care bleeding risk calculator and to document changes in anticoagulant use and bleeding complications after implementation of use of this calculator.

DESIGN: Prospective observational pilot study with a historical control cohort.

SETTING: Tertiary care medical center.

PATIENTS: The pilot cohort consisted of 100 patients undergoing ad hoc PCI during elective cardiac catheterization procedures between January and May 2013, whose bleeding risk and accompanying PCI anticoagulant recommendations were determined by the use of a pre-PCI point-of-care bleeding risk calculator. The historical control cohort consisted of all patients who underwent elective PCI at the same facility between April 1, 2011, and March 31, 2012, before implementation of use of the bleeding risk calculator.

MEASUREMENTS AND MAIN RESULTS: The pre-PCI bleeding risk calculator distinguished patients in the pilot cohort as high risk (score 12 or higher) or low risk (lower than 12) for bleeding after a PCI procedure. The primary outcome was bivalirudin use in the pilot cohort compared with its use in the historical control cohort. Implementation of the bleeding risk calculator significantly decreased bivalirudin use compared with bivalirudin use in the historical control cohort (87% in the control cohort vs 60% in the pilot cohort, p

CONCLUSION: A simple bleeding risk calculator can substantially reduce overall bivalirudin use by specifically decreasing its use among patients at low bleeding risk while maintaining its use among patients at high bleeding risk. The incidence of bleeding complications remained unchanged despite decreasing bivalirudin use among patients undergoing elective coronary catheterization who were at low risk for bleeding.
