What must be done with patients at the CCP for documentation purposes?

Tagging patients with a bar code at the Casualty Collection Point (CCP) is essential for accurate tracking and documentation during an active shooter incident or other mass casualty scenarios. This method facilitates the efficient management of patient information, allowing responders to link medical treatment and assessment to each individual. This process minimizes the potential for errors in patient care and ensures that each patient's status is clearly recorded, which is critical for maintaining a comprehensive account of the incident.

Implementing barcodes aids in quick retrieval of data related to patient treatments, transfers, and outcomes, thus enhancing the overall response and coordination efforts. While other options may involve aspects of patient care or documentation, tagging with a bar code is specifically tailored to ensure meticulous tracking and accountability in chaotic environments, making it the most effective choice for documentation purposes at the CCP.
