Nearly 80% of level I\/II centers in the South and West exceeded 80% inpatient occupancy for 75 weeks or longer. In contrast, level III and lower-level centers showed lower occupancy but notable regional variation. Simulation modeling revealed that at sustained influx rates of 1500 to 2000 patients per day, national trauma bed deficits exceeded 20\u202f000 beds within 45 days. Even modest influxes of 241 patients per day saturated all designated trauma beds within 90 days under dynamic length-of-stay assumptions.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec id=\"ab-soi250096-10\">\n                    <jats:title>Conclusions and Relevance<\/jats:title>\n                    <jats:p>The US trauma system, particularly its tertiary centers (level I\/II) are operating under sustained high occupancy with limited reserve capacity for patient surges.
