“…In 2011, injuries were responsible for more than 40 million visits to emergency departments (EDs) in the United States (National Center for Health Statistics & Ambulatory and Hospital Care Statistics Branch, n.d.). Pain is reported in at least 70% of trauma-related injuries (Berben, Schoonhoven, Meijs, van Vugt, & van Grunsven, 2011), and undertreated acute pain may contribute to delirium, particularly in geriatric patients (McKeown, 2015); prolonged need for mechanical ventilation; and delayed mobilization (Barr et al, 2013). Acute pain is cited as a predictor of chronic pain development (McGreevy, Bottros, & Raja, 2011; Trevino, Harl, Deroon-Cassini, Brasel, & Litwack, 2014).…”
