Though <jats:italic>not alert\u201d falls<\/jats:italic> patients with severe outcomes mostly are \u201chot\u201d transported to the hospital, some of these cases may be due to other acute medical events (cardiac, respiratory, circulatory, or neurological), which may not always be apparent to the emergency medical dispatcher (EMD) during call processing.<\/jats:p><\/jats:sec><jats:sec id=\"S1049023X00008232_sec02\"><jats:title><jats:bold>Objectives:<\/jats:bold><\/jats:title><jats:p>The objective of this study was to characterize the risk of cardiac arrest and \u201chot-transport\u201d outcomes in patients with \u201cnot alert\u201d condition, within the Medical Priority Dispatch System (MPDS\u00ae) Falls protocol descriptors.<\/jats:p><\/jats:sec><jats:sec id=\"S1049023X00008232_sec03\" sec-type=\"methods\"><jats:title><jats:bold>Methods:<\/jats:bold><\/jats:title><jats:p>This retrospective study used 129 months of de-identified, aggregate, dispatch datasets from three US emergency communication centers. The communication centers used the Medical Priority Dispatch System version 11.3\u2013OMEGA type (released in 2006) to interrogate Emergency Medical System callers, select dispatch codes assigned to various response configurations, and provide pre-arrival instructions. The distribution of cases and percentages of cardiac arrest and hot-transport outcomes, categorized by MPDS\u00ae code, was profiled.
