The study analyzed the process of diffusion as it functions in regard to changes in nursing practice in a selected segment of Canadian hospitals. Three aspects of diffusion were investigated: (1) the flow of new information in nursing through a newwork of hospitals; (2) factors affecting the adoption of new nursing practices; and (3) factors influencing delay in the adoption process, rejection of innovations, or the discontinuation after adoption. The population comprised 85 public general hospitals in the province of British Columbia. An analytical survey method was used and the structured interview technique employed to gather data from the Director of Nursing of each hospital. Significant findings in regard to sources of information included: (1) the importance of interpersonal communication with colleagues; (2) the high ranking of continuing education programs as an initial source of new knowledge; and (3) the role of the hospital supply house salesman in disseminating information to nurses. Influence came from the major teaching and research centers of Vancouver, and from large, centrally located hospitals of the province. Factors influencing delay, rejection or discontinuation were shown to be related both to characteristics of the new practice and to characteristics of the individuals involved in making the decision to adopt innovations.
