FACTORS TO BE considered by the CNS before implementing the role in private practice with a physician are discussed. Four CNSs were interviewed regarding their experiences in such a practice. The CNS subroles of expert practitioner, educator, consultant, and researcher are described as they apply in private practice with a physician. A four-step process is proposed to guide the CNS considering entry into private practice. The steps discussed are: self-assessment, evaluation of the legal and financial aspects, development of marketing and cost-justification strategies, and negotiating for a position. A method for cost justification is proposed, and some elements of marketing and negotiating are reviewed.
