Abstract
Effectiveness is difficult to define or measure, but is frequently associated with cost. A two phase study conducted with occupational health nurses in Alberta, Canada resulted in a beginning model for effectiveness. In 1997, Phase One of an exploratory descriptive study focused on physical assessment by occupational health nurses (N = 137) and perceptions of effectiveness in practice (n = 104). In 2001, Phase Two used focus groups (n = 7) to determine occupational health nurses' reactions to the preliminary analysis of questionnaire responses on effectiveness. The focus groups confirmed and expanded categories, and reconfigured the developing model. The model makes explicit the foundations, functions, relationships, and goals for effectiveness in occupational health nursing practice. The foundation includes registered nurse (RN) experience and baseline competence comprising occupational health nursing education, RN and occupational health nurse experience, and multidisciplinary knowledge. Ten specific functions and nine relationships describe the occupational health nursing specialty practice and promote achievement of five goals: balance, communication, continuing competence, leadership, and trust. The goal of balance needs articulation in the nursing literature.
