Effect of emergency medicine pharmacists on medication-error reporting in an emergency department.

Purpose: The effect of an emergency medicine (EM) clinical pharmacist on medication-error reporting in an emergency department (ED) was studied.

Methods: The medication-error reports for patients seen at a university's ED between September 1, 2005, and February 28, 2009, were retrospectively reviewed. Errors reported before the addition of an EM pharmacist (from September 1, 2005, through February 28, 2006) were compared with those reported after the addition of two EM pharmacists (from September 1, 2008, through February 28, 2009).
