The Feasibility of Pertussis Immunization in a Canadian Emergency Department

University of Prince Edward Island644 enrolled

Overview

Randomized controlled trial of 2 strategies to provide adults with the Tdap vaccine to patients presenting to the emergency department. Rates of vaccination as well as effects on department efficiency will be measured.

This study is a prospective randomized, controlled trial of two strategies to provide patients with the pertussis vaccine. Eligible adult patients with be offered pertussis vaccination in the Emergency Department vs. a referral to Public Health for pertussis vaccination.

Five statements rated on 5 point likert scale (strongly disagree (1) to strongly agree (5)). The immunization strategy significantly increased my workload; patient care was negatively affected by the immunization strategy; I was unable to provide the standard of care because of the immunization strategy; patient flow within the department was negatively affected by the immunization strategy; the ED should implement the immunization strategy
