BACKGROUND Anticoagulants and prescription antiplatelet (ACAP) agents widely used by older adults have the potential to adversely affect traumatic brain injury (TBI) outcomes. We hypothesized that TBI patients on preinjury ACAP agents would have worse outcomes than non-ACAP patients. METHODS This was a 5.5-year retrospective review of patients 55 years(More)
BACKGROUND Trauma centers are more frequently evaluating patients who are receiving anticoagulant or prescription antiplatelet (ACAP) therapy at the time of injury. Because there are reports of delayed intracranial hemorrhage (ICH) after blunt trauma in this patient group, we evaluated patients receiving ACAP with a head computed tomography (CT) on(More)
BACKGROUND Major peripheral vascular trauma is managed by several surgical specialties. The impact of surgical specialty training and certification on outcome has not been evaluated. We hypothesized that general surgeons without specialty training in vascular surgery would have outcomes equivalent to surgeons with vascular training in the management of(More)
BACKGROUND Optimal care of trauma patients requires cost-effective organization and commitment of trauma center resources. We examined the impact of creating a dedicated trauma care unit (TCU) and adding advanced practice nurses on the quality and cost of care at an adult Level I trauma center. METHODS Patient demographic and injury data, length of stay,(More)
BACKGROUND Recent innovations in care have improved survival following injury. Coincidentally, the population of elderly injured patients with preexisting comorbidities has increased. We hypothesized that this increase in elderly injured patients may have combined with recent care innovations to alter the causes of death after trauma. METHODS We reviewed(More)
Elevated serum uric acid (UA) is associated with cardiovascular disease (CVD) but its association with coronary artery calcium (CAC) is inconsistent. This study examined ethnic differences in the association of UA levels with CAC severity and progression. Participants included 202 white and 166 Filipino postmenopausal women without known CVD. White women(More)
BACKGROUND Epidemiologic trends in trauma-related mortality in the United States require updating and characterization. We hypothesized that during the past decade, there have been changing trends in mortality that are associated with multiple public health and health care-related factors. METHODS Multiple sources were queried for the period of 2002 to(More)
BACKGROUND Venous duplex surveillance (VDS) is commonly used in trauma patients considered at risk for deep venous thrombosis. Economic evaluations have not addressed the quality of either the process of care or the outcomes achieved through the use of VDS. We sought to determine the value (quality/cost) of VDS in trauma patients stratified by risk for(More)
BACKGROUND Withdrawal or limitation of care (WLC) in trauma patients has not been well studied. We reviewed 10 years of deaths at our adult Level I trauma center to identify the patients undergoing WLC and to describe the process of trauma surgeon-managed WLC. METHODS This is a retrospective review of WLC. Each patient was assigned to one of three modes(More)
This study examined childhood physical or sexual abuse, involvement in dependency or delinquency systems, psychiatric hospitalization, and suicide as possible risk factors for survival sex among homeless young women. Homeless young women were found to have similarly high rates of childhood sexual abuse, dependency and delinquency systems involvement, and(More)
