Changes within the health care system necessitate changes in nursing practice. Given the financial environment and the need to balance the cost/quality equation, case management will become increasingly important and has the potential to become the predominant care delivery system of the 1990s. This transition represents a tremendous opportunity for nursing. The CCM role offers many potential advantages and benefits for individual nurses and the profession as a whole. Nurses practicing as case managers have the opportunity to function in a highly professional, independent manner with a great deal of interdisciplinary collaboration. In addition to the challenges and satisfactions of the work itself, the nurse case manager may also enjoy a higher salary and more scheduling control and flexibility. The broader advantages of case management include its benefits to patients and institutions and its fit with current trends in the health care environment. Nurse case managers manage hospital systems to produce optimal clinical outcomes for patients in the shortest time using as few resources as possible. This approach to care delivery places nurses in a position to demonstrate the tremendous contribution they can make to achieving the institution's goal of delivering high-quality, cost-effective care. Thus, case management fits extremely well with current trends in health care financing and outcome measurement. The model described in this article illustrates one approach to implementing these important concepts in a critical care setting.
