Outcome after major trauma: 12-month and 18-month follow-up results from the Trauma Recovery Project

BACKGROUND The importance of outcome after major injury has continued to gain attention in light of the ongoing development of sophisticated trauma care systems in the United States. The Trauma Recovery Project (TRP) is a large prospective epidemiologic study designed to examine multiple outcomes after major trauma in adults aged 18 years and older, including quality of life, functional outcome, and psychologic sequelae such as depression and posttraumatic stress disorder (PTSD). Patient outcomes were assessed at discharge and at 6, 12, and 18 months after discharge. The specific objectives of the present report are to describe functional outcomes at the 12-month and 18-month follow-ups in the TRP population and to examine the association of putative risk factors with functional outcome. METHODS Between December 1, 1993, and September 1, 1996, 1,048 eligible trauma patients triaged to four participating trauma center hospitals in the San Diego Regionalized Trauma System were enrolled in the TRP study. The admission criteria for patients were as follows: (1) age 18 years or older; (2) Glasgow Coma Scale score on admission of 12 or greater; and (3) length of stay greater than 24 hours. Functional outcome after trauma was measured before and after injury using the Quality of Well-Being (QWB) Scale, an index sensitive to the well end of the functioning continuum (0 = death, 1.000 = optimum functioning). Follow-up at 12 months after discharge was completed for 806 patients (79%), and follow-up at 18 months was completed for 780 patients (74%). Follow-up contact at any of the study time points (6, 12, or 18 months) was achieved for 926 (88%) patients. RESULTS The mean age was 36 +/- 14.8 years, and 70% of the patients were male; 52% were white, 30% were Hispanic, and 18% were black or other. Less than 40% of study participants were married or living together. The mean Injury Severity Score was 13 +/- 8.5, with 85% blunt injuries and a mean length of stay of 7 +/- 9.2 days. QWB scores before injury reflected the norm for a healthy adult population (mean, 0.810 +/- 0.171). At the 12-month follow-up, there were very high levels of functional limitation (QWB mean score, 0.670 +/- 0.137). Only 18% of patients followed at 12 months had scores above 0.800, the norm for a healthy population. There was no improvement in functional limitation at the 18-month follow-up (QWB mean score, 0.678 +/- 0.130). The majority of patients (80%) at the 18-month follow-up continued to have QWB scores below the healthy norm of 0.800. Postinjury depression, PTSD, serious extremity injury, and intensive care unit days were significant independent predictors of 12-month and 18-month QWB outcome. CONCLUSION This study demonstrates a prolonged and profound level of functional limitation after major trauma at 12-month and 18-month follow-up. This is the first report of long-term outcome based on the QWB Scale, a standardized quality-of-life measure, and provides new and provocative evidence that the magnitude of dysfunction after major injury has been underestimated. Postinjury depression, PTSD, serious extremity injury, and intensive care unit days are significantly associated with 12-month and 18-month QWB outcome.

Morphine Use after Combat Injury in Iraq and Post-Traumatic Stress Disorder

BACKGROUND Post-traumatic stress disorder (PTSD) is a common adverse mental health outcome among seriously injured civilians and military personnel who are survivors of trauma. Pharmacotherapy in the aftermath of serious physical injury or exposure to traumatic events may be effective for the secondary prevention of PTSD. METHODS We identified 696 injured U.S. military personnel without serious traumatic brain injury from the Navy-Marine Corps Combat Trauma Registry Expeditionary Medical Encounter Database. Complete data on medications administered were available for all personnel selected. The diagnosis of PTSD was obtained from the Career History Archival Medical and Personnel System and verified in a review of medical records. RESULTS Among the 696 patients studied, 243 received a diagnosis of PTSD and 453 did not. The use of morphine during early resuscitation and trauma care was significantly associated with a lower risk of PTSD after injury. Among the patients in whom PTSD developed, 61% received morphine; among those in whom PTSD did not develop, 76% received morphine (odds ratio, 0.47; P<0.001). This association remained significant after adjustment for injury severity, age, mechanism of injury, status with respect to amputation, and selected injury-related clinical factors. CONCLUSIONS Our findings suggest that the use of morphine during trauma care may reduce the risk of subsequent development of PTSD after serious injury.

Blunt carotid artery dissection : incidence, associated injuries, screening, and treatment

Blunt carotid dissection (BCD) is a rare injury occurring in less than one in 1,000 victims of blunt injuries. Using a 4-year experience in a trauma system with 14 cases of BCD, we performed a matched blunt trauma patient case-control analysis to determine if there were patterns of injuries that were associated with increased risk of BCD. Patients with combinations of head, facial, and cervical spine injuries with or without extremity fractures proved to be at significantly increased risk for BCD. Duplex scanning appears to be a useful screening tool for these patients. Anticoagulation was the preferred treatment once neurologic deficits were present.

Outcome after major trauma: discharge and 6-month follow-up results from the Trauma Recovery Project

BACKGROUND The study of both short-term and long-term outcomes after major trauma has become an increasingly important focus of injury research because of the improved survival rates attributable to the evolution of sophisticated trauma care systems. The Trauma Recovery Project (TRP) is a large prospective epidemiologic study designed to examine multiple outcomes after major trauma in adults aged 18 years and older, including quality of life, functional outcome, and psychologic sequelae such as depression and posttraumatic stress disorder (PTSD). Patient outcomes were assessed at discharge and at 6, 12, and 18 months after discharge. The specific objectives of the present report are to describe functional outcomes at the discharge and 6-month follow-up time points in the TRP population and to examine the association of putative risk factors with functional outcome. METHODS Between December 1, 1993, and September 1, 1996, 1,048 eligible trauma patients triaged to four participating trauma center hospitals in the San Diego Regionalized Trauma System were enrolled in the TRP study. The admission criteria for patients were as follows: (1) age 18 years or older, (2) Glasgow Coma Scale score on admission of 12 or greater, and (3) length of stay greater than 24 hours. Functional outcome after trauma was measured before and after injury using the Quality of Well-Being (QWB) scale, a more sensitive index to the well end of the functioning continuum (range, 0 = death to 1.000 = optimum functioning). Functional outcome was also measured using a standard activities of daily living (ADL) scale (range, 13 = full function to 47 = maximum dysfunction). Follow-up at 6 months after discharge was completed for 826 patients (79%). RESULTS The mean age was 36 +/- 14.8 years; 70% of the patients were male; 52% of the patients were white, 30% were Hispanic, and 18% were black or other. Less than 40% of study participants were married or living with a partner. The mean Injury Severity Score was 13 +/- 8.5, with 85% blunt injuries, and a mean length of stay of 7 +/- 9.2 days. QWB scores before injury reflected the norm for a healthy adult population (mean, 0.810 +/- 0.171). After major trauma, QWB scores at discharge showed a significant degree of functional limitation (mean, 0.401 +/- 0.045). At 6-month follow-up, QWB scores continued to show high levels of functional limitation (mean, 0.633 +/- 0.122). Limitation measured using the standard ADL scale found only moderate dysfunction at discharge (mean, 30.0 +/- 7.7) and at 6-month follow-up (mean, 15.0 +/- 4.2). Postinjury depression, PTSD, serious extremity injury, and length of stay were significant independent predictors of 6-month QWB outcome. CONCLUSION Postinjury functional limitation is a clinically significant complication in trauma patients at discharge and a 6-month follow-up. The QWB yields a more sensitive assessment of functional status than traditional ADL instruments. Postinjury depression, PTSD, serious extremity injury, and length of stay are significantly associated with 6-month QWB outcome.

Perceived threat to life predicts posttraumatic stress disorder after major trauma: risk factors and functional outcome.

BACKGROUND The importance of psychological morbidity after major trauma, such as posttraumatic stress disorder (PTSD), is continuing to gain attention in trauma outcomes research. The Trauma Recovery Project is a large prospective epidemiologic study designed to examine multiple outcomes after major trauma, including quality of life (QoL) and PTSD. The specific objectives of the present report are to examine risk factors for PTSD and to assess the impact on QoL at the 6-, 12-, and 18-month follow-up time points in the Trauma Recovery Project population. METHODS Between December 1, 1993, and September 1, 1996, 1,048 eligible trauma patients triaged to four participating trauma center hospitals in the San Diego Regionalized Trauma System were enrolled in the study. The enrollment criteria for the study included age 18 years and older, admission Glasgow Coma Scale score of 12 or greater, and length of stay > 24 hours. QoL was measured after injury using the Quality of Well-being scale, a sensitive index to the well end of the functioning continuum (range, 0 = death to 1.000 = optimum functioning). Early symptoms of acute stress reaction (SASR) at discharge were assessed using the Impact of Events Scale (score > 30 = SASR). PTSD at 6-month follow-up was diagnosed using standardized Diagnostic and Statistical Manual of Mental Disorders, 4th Edition, criteria. Patient outcomes were assessed at discharge and at 6, 12, and 18 months after discharge. RESULTS PTSD was diagnosed in 32% (261 of 824) patients at 6-month follow-up. Perceived threat to life predicted PTSD onset (odds ratio [OR], 1.6; p < 0.01) and early SASR (OR, 2.2; p < 0.001). PTSD was more frequent in women (39%) than in men (29%) and in younger low-income patients. Other major risk factors were penetrating trauma (OR, 2.3; p < 0.001) and assaults (OR, 1.5; p < 0.05). PTSD had a major impact on QoL at 6-, 12-, and 18-month follow-up (Quality of Well-being scale score: 6 months, 0.576 vs. 0.658; 12 months, 0.620 vs. 0.691; 18 months, 0.620 vs. 0.700; p < 0.0001). CONCLUSION These results provide new and provocative evidence that perceived threat to life and mechanism predict PTSD after major traumatic injury. PTSD had a prolonged and profound impact on short- and long-term outcome and QoL.

The impact of major trauma: quality-of-life outcomes are worse in women than in men, independent of mechanism and injury severity.

BACKGROUND The importance of gender differences in quality of life and psychologic morbidity after major trauma is a newly recognized focus of trauma outcomes research. The Trauma Recovery Project is a large, prospective, epidemiologic study designed to examine multiple outcomes after major trauma, including quality of life (QoL), and psychologic sequelae such as depression and early symptoms of acute stress reaction (SASR). The specific objectives of the present report are to examine gender differences in QoL outcomes and the early incidence of combined depression and SASR after injury, controlling for injury severity, specific body area injured, and mechanism. METHODS Between December 1, 1993, and September 1, 1996, 1,048 eligible trauma patients triaged to four participating trauma center hospitals in the San Diego Regionalized Trauma System were enrolled in the study. The enrollment criteria for the study included age 18 years and older, admission Glasgow Coma Scale score of 12 or greater, and length of stay greater than 24 hours. QoL outcome after trauma was measured after injury using the Quality of Well-being scale, a sensitive index to the well end of the functioning continuum (range, 0 = death to 1.000 = optimum functioning). Depression was assessed using the Center for Epidemiologic Studies scale. SASR was assessed using the Impact of Events scale. Patient outcomes were assessed at discharge and at 6, 12, and 18 months after discharge. RESULTS Women (n = 313) were significantly more likely to have poor QoL outcomes at follow-up than men (n = 735) (women vs. men: 12-month follow-up odds ratio [OR] = 2.2, p < 0.001; 18-month follow-up OR = 2.0, p < 0.001). Quality of Well-being scores at each of the 6-, 12-, and 18-month follow-up time points were markedly and significantly lower in women compared with men, independent of injury severity, serious and moderate injury status, lower extremity injury, intentional or unintentional injury type, and blunt or penetrating injury. Women were also significantly more likely to develop early combined depression and SASR at discharge (OR = 1.7, p < 0.01) and to have continuous depression throughout the 18-month follow-up period (OR = 2.3, p < 0.001). CONCLUSION These analyses provide further important and more detailed evidence that women are at risk of worse QoL outcomes and early psychologic morbidity after major trauma than men, independent of mechanism and injury severity. A better understanding of the impact of major trauma in men and women will be an important component of efforts to improve trauma care and long-term outcome in mature trauma systems.

Trauma in Pregnancy: Maternal and Fetal Outcomes

OBJECTIVE Pregnancy imposes significant physiologic demands that may confuse and complicate the evaluation, resuscitation, and definitive management of pregnant women who sustain trauma. Accurate prediction of fetal outcome after trauma remains elusive. The objective of this study was to characterize patterns of injury in pregnant women, to determine if pregnancy affects maternal morbidity and mortality after trauma, and to identify predictors of fetal death. METHODS We performed a retrospective, case-control analysis of all injured pregnant patients admitted to the Trauma Service at the University of California San Diego Medical Center from 1985 to 1995. RESULTS We identified 114 injured pregnant patients. Motor vehicle crashes accounted for 70% of injuries, and of these, 46% of patients were not using seat belts or helmets. Violence accounted for 12% of injuries. Injured pregnant women with Injury Severity Scores > 8 demonstrated similar mortality, morbidity, and length of stay to matched nonpregnant control patients. Pregnant women were more likely to sustain serious abdominal injury and were less likely to sustain severe head injury. Identified risk factors for fetal loss include maternal death, overall maternal injury severity, the presence of severe abdominal injury, and the presence of hemorrhagic shock. CONCLUSION There appears to be a group of pregnant women in San Diego at high risk for traumatic injury who should be targeted for preventative strategies including improved seat belt use. Pregnancy does not increase mortality or morbidity after trauma but influences the pattern of injury. Maternal death, high Injury Severity Score, serious abdominal injury, and hemorrhagic shock are risk factors for fetal loss.

The importance of gender on outcome after major trauma: functional and psychologic outcomes in women versus men.

BACKGROUND Outcome after major trauma is an increasingly important focus of injury research. The effect of gender on functional and psychological outcomes has not been examined. The Trauma Recovery Project is a large, prospective, epidemiologic study designed to examine multiple outcomes after major trauma, including quality of life, functional outcome, and psychological sequelae such as depression and early symptoms of acute stress reaction. The specific objectives of the present report are to examine gender differences in short- and long-term functional and psychological outcomes in the Trauma Recovery Project population. METHODS Between December 1, 1993, and September 1, 1996, 1,048 eligible trauma patients triaged to four participating trauma center hospitals in the San Diego Regionalized Trauma System were enrolled in the study. The enrollment criteria for the study included age 18 years and older, admission Glasgow Coma Scale score of 12 or greater, and length of stay greater than 24 hours. Quality of life was measured after injury using the Quality of Well-being scale, a sensitive index to the well end of the functioning continuum (range, 0 = death to 1.000 = optimum functioning). Depression was assessed using the Center for Epidemiologic Studies Depression scale and early symptoms of acute stress reaction were assessed using the Impact of Events scale. Patient outcomes were assessed at discharge and at 6, 12, and 18 months after discharge. RESULTS Functional outcome was significantly worse at each follow-up time point in women (n = 313) versus men (n = 735). Quality of Well-being scale scores were markedly and significantly lower at 6-month follow-up in women compared with those in men (0.606 vs. 0.646, p < 0.0001). This association persisted at 12-month (0.637 vs. 0.6685, p < 0.0001) and 18-month (0.646 vs. 0.6696, p < 0.0001) follow-up. Women were also significantly more likely to be depressed at all follow-up time points (discharge odds ratio [OR] = 1.4, p < 0.05; 6-month follow-up OR = 2.2, p < 0.01; 12-month follow-up OR = 2.0, p < 0.01; 18-month follow-up OR = 2.2, p < 0.01) and to have early symptoms of acute stress reaction at discharge (OR = 1.4, p < 0.05). These differences remained significant and independent after adjusting for injury severity, mechanism, age, and sociodemographic factors. CONCLUSION Women are at risk for markedly worse functional and psychological outcomes after major trauma than men, independent of injury severity and mechanism. Gender differences in short- and long-term trauma outcomes have important implications for future studies of recovery from trauma.

The association of lifetime weight and weight control patterns with bone mineral density in an adult community

We examined the association of lifetime weight and weight change to bone mineral density (BMD) at four skeletal sites, the radial shaft, the ultradistal wrist, the total hip and lumbar spine, in a community-based population of 1043 older white men and women. In those currently overweight (body mass indices (BMI) > 26), the age-adjusted mean BMD at all sites was significantly higher than in those with BMI less than 26. Lifetime maximum BMI was also positively and significantly associated with a higher age-adjusted BMD at all sites except the ultradistal wrist in men. Weight gain or fluctuation of 10 lbs or more between the ages of 40 and 60 was associated with significantly higher age-adjusted mean BMD at all sites compared to weight loss or no weight change in both men and women. Weight at age 18 was unassociated with BMD but weight gain after age 18 was associated with significantly higher age-adjusted mean BMD at all sites. Conversely, dieting, weight loss or a lifetime maximum BMI of less than 24 were all associated with markedly lower BMD at all sites in both sexes. Weight patterns were closely correlated with current BMI; most of these trends persisted but were no longer statistically significant after controlling for current weight.

The impact of major in-hospital complications on functional outcome and quality of life after trauma.

BACKGROUND Little is known about the impact of major in-hospital complications on functional outcome in the short- and long-term period after serious injury. The Trauma Recovery Project (TRP) is a large, prospective, epidemiologic study designed to examine multiple outcomes after major trauma, including quality of life and functional limitation. Patient outcomes were assessed at discharge and at 6, 12, and 18 months after discharge. The specific objectives of the present report are to examine the effect of postinjury complications on functional outcomes at discharge and at 6-, 12-, and 18-month follow-up time points in the TRP population. METHODS Between December 1, 1993, and September 1, 1996, 1,048 eligible trauma patients triaged to four participating trauma center hospitals in the San Diego Regionalized Trauma System were enrolled in the study. The enrollment criteria for the study included age 18 years or older; admission Glasgow Coma Scale score of 12 or greater; and length of stay greater than 24 hours. Quality of life was measured after injury using the Quality of Well-being (QWB) scale, a sensitive index to the well end of the functioning continuum (range, 0 [death] to 1.000 [optimum functioning]). Major in-hospital complications were assessed for 820 patients and were coded as pulmonary, cardiovascular, gastrointestinal, hepatic, hematologic, infections, renal, musculoskeletal, neurologic, and vascular, on the basis of standardized codes used in the Trauma Registry. RESULTS Major in-hospital complications were present in 83 (10.1%) patients. Discharge QWB scores were significantly lower in patients with major complications (0.394 vs. 0.402, p < 0.05). QWB scores were also significantly lower at 6-month follow-up in patients with major complications (0.575 vs. 0.637, p < 0.0001). Types of major complications with significantly lower 6-month follow-up QWB scores were pulmonary, gastrointestinal, infections, and musculoskeletal. Patients with major complications also had significantly lower 12-month (0.626 vs. 0.674, p < 0.01) and 18-month (0.646 vs. 0.681, p < 0.05) follow-up QWB scores. Pulmonary major complications and infections were associated with significantly lower QWB scores at 12-month follow-up. CONCLUSION These results provide new evidence that major in-hospital complications may have an important impact on functional outcomes after major trauma.
