The Kootenay Boundary (KB) region has a high incidence of pertussis compared to other areas in the province of British Columbia (BC), and NPs [nurse practitioners] can be effective agents of change to reduce this incidence. The focus of this project is to critically examine and provide a guide to NPs working in primary care on the following question: what is the role of the NP in primary health care in increasing the immunization rates of adult dTap and subsequently decreasing pertussis morbidity in the KB population?
