Physiologic measurement of patient acuity has been used to predict patient outcomes, length of stay, and resource utilization. To date, these tools are not sufficiently comprehensive to inform nurse staffing assignments and have limited practical application. The Complexity Assessment and Monitoring to Ensure Optimal Outcomes (CAMEO©) acuity tool was initially developed and validated to quantify patient acuity in terms of complexity of nursing cognitive workload in pediatric intensive care units (ICU).
