The article by Matsushima et al1 gives a new perspective on regionalization of care for trauma. In elderly patients who have been treated at level 1 and level 2 trauma centers in Pennsylvania, the authors noted a 25% decrease in mortality for those at centers that treat more than 100 geriatric patients annually. These high-volume geriatric trauma centers have lower rates of major complications, even lower incidences of failure to rescue after a major complication when compared with centers with fewer than 100 such patients annually. Conversely, at institutions that have larger numbers of nongeriatric trauma patients, there was a significantly higher rate of major complications for elderly individuals.
