This chapter reviews patient and nursing care models, patient classification systems (PCSs), staffing and scheduling models, leader and manager staffing and scheduling responsibilities, and ways to make self-scheduling a positive experience for nurses. The primary/total patient care delivery model is the oldest model with its origins coming from the work of Florence Nightingale, and echoed in patient care provided by nursing students. PCSs are used to provide a quantitative measure of workload for the determination of staffing needs by measuring the amount of care a patient requires using objective measures such as vital signs, treatments, and number of medications. According to the American Organization of Nurse Executives competencies for nurse managers, the responsibilities of the manager include the following: staff selection, evaluation of staffing patterns, matching staff competencies to assignments, defining the role of the staff members within their scope of practice, and completing and evaluating the orientation process.
