CommandGradientErrorinPre-HospitalCare This document discusses the concept of command gradient error and how differences in rank can inhibit communication and compromise patient care. It notes that perceived or actual differences in rank between healthcare providers can lead to a loss of shared understanding of the situation, or joint mental model, which could result in an undesirable event for the patient. It advocates for using graded assertiveness through the PACE model (Probe, Alert, Challenge, Emergency) to overcome rank differences and ensure patient safety remains the top priority.
