This document is a guide that outlines the ESO Health Data Exchange (HDE) and its benefits for hospitals and emergency medical services (EMS). It describes how HDE enhances situational awareness regarding EMS transport logistics by integrating discrete EMS data elements into patient medical records. This integration is aimed at improving treatment speed and patient outcomes. The guide details how hospitals can leverage HDE to address challenges associated with outdated processes that hinder operational efficiency and clinical insight. It explains that HDE enables hospitals to drive strategic volume by analyzing facility and service line volumes, improve operational efficiency by reducing data gathering and entry time, and support clinical quality by providing access to meaningful data at the point of care. The document also mentions the positive impact of HDE on collaboration between EMS and hospitals, ultimately contributing to better health and safety outcomes for communities.
