Optimizing nurse assignments is crucial for maintaining quality care and improving patient outcomes, as nurse staffing represents 40% of hospital costs. A change from assigning nurses at random to using scientific criteria has affected operations, funding, worker happiness, and patient safety. Patient diagnoses, continuity of care, and nurse-to-patient ratios are important factors to take into account. Improving nursing productivity and lowering turnover now depend on skill mapping, which assesses nurses' competencies according to hospital requirements. Improving nurse satisfaction and the caliber of patient care requires effective staffing strategies that are adapted to the needs and acuity of the patients. This review of the literature looks at how skill mapping and acuity tools can be combined to improve patient outcomes, maximize resource usage, and improve nursing activities. It demonstrates how useful Perroca's instrument is in guiding care planning and management decisions.
