What action should an officer take when no patient is found after a complete search?

The appropriate action for an officer when no patient is found after a complete search is to review the response printout for further information. This printout contains valuable data regarding the initial call, including location details, nature of the incident, and any additional context that may assist in understanding the situation better. By reviewing this information, the officer may uncover critical insights that could help clarify the circumstances surrounding the response, such as whether there were any reports of a patient that could have been missed.

In contrast, leaving the scene immediately would be premature without exhausting all avenues to gather information. Contacting dispatch for additional details can be useful, but it may not provide the immediate context contained in the response printout. Asking nearby residents for information could potentially yield helpful insights, but it is more systematic to first reference the established information in the printout, which is designed to assist officers in these situations. Therefore, reviewing the response printout helps ensure that no relevant data is overlooked before taking further actions.
