What consequence arises when emergency department throughput exceeds five to seven critical casualties per hour?

When emergency department throughput exceeds five to seven critical casualties per hour, most critical care processes become unmanageable due to the overwhelming demand placed on the available resources. This situation can lead to bottlenecks in patient assessment and treatment, as the staff may be unable to keep up with the volume of cases presenting simultaneously. Emergency departments are structured to function optimally under a certain capacity; exceeding this threshold can compromise patient safety and care quality. Triage processes become strained, leading to delays in treatment, potential mismanagement of critical cases, and an increased likelihood of errors, ultimately impacting patient outcomes negatively.

In this context, while improved patient outcomes, reduced staffing requirements, or shortened treatment times may seem like potential benefits, they are unrealistic when the department is overwhelmed. The focus shifts from effective care to merely attempting to manage an unmanageable volume of cases, underlining the complexity and challenges faced in emergency care environments.
