Racial and Ethnic Differences in Limiting Life-Sustaining Treatment in Trauma Patients

Introduction: Differences in health care between racial and ethnic groups exist. The literature suggests that African Americans and Hispanics prefer more aggressive treatment at the end of life. The aim of this study is to assess racial and ethnic differences in limiting life-sustaining treatment (LLST) after trauma. Study Design: We performed a 2-year (2013-2014) retrospective analysis of Trauma Quality Improvement Program database. Patients with age ≥16 and Injury Severity Score (ISS) ≥ 16 were included. Outcome measures were the incidence and the predictors of LLST. Multivariable logistic regression was performed to control for confounding variables. Results: A total of 97 024 patients were identified. Mean age was 49 (21) years, 68% were male, 68% were white, and 14% were Hispanic. The overall incidence of LLST was 7.2%. Based on race, LLST was selected as consistent with goals of care more often in white when compared to African American individuals who experience serious traumatic injury (8.0% vs 4.5%; P < .001). Based on ethnicity, LLST was more often selected in non-Hispanics (7.5% vs 5.2%, P < .001) when compared to Hispanics. On regression analysis, the independent predictors of LLST were white race (odds ratio [OR]: 2.7 [1.6–4.4], P = .02), non-Hispanic ethnicity (OR: 1.9 [1.4-4.6]; P = .03), severe head injury (OR: 1.7 [1.1-3.2]; P = .04), and ISS (OR: 3.1 [2.4-5.1]; P < .01). Conclusions: Differences exist in selecting LLST between different racial and ethnic groups in severe trauma. African Americans and Hispanics are less likely to select LLST when compared to whites and non-Hispanics. Further studies are required to analyze the factors associated with selecting LLST in African Americans and Hispanics.

Splanchnic Hypoperfusion

Splanchnic hypoperfusion as reflected by gastric intramucosal acidosis has been recognized as an important determinant of outcome in shock. A comprehensive splanchnic hypoperfusion-ischemia reperfusion (IRP) protocol was evaluated against conventional shock management protocols in critical trauma patients. The study was a prospective randomized trial comparing three therapeutic approaches to hypoperfusion after severe trauma in 151 trauma patients admitted to the intensive care unit. Group 1 patients received hemodynamic support based on conventional indicators of hypoperfusion. In group 2, resuscitation was further guided by gastric tonometry-derived estimates of splanchnic hypoperfusion and included more invasive hemodynamic monitoring and additional administration of colloid or crystalloid solutions, or inotropic support. Group 3 patients additionally received therapies specifically aimed at optimizing splanchnic perfusion and minimizing oxidant-mediated damage from reperfusion. The three groups were similar based on age, Injury Severity Score, and Acute Physiology and Chronic Health Evaluation II Scores. There were no statistically significant differences in mortality rates, organ dysfunction, ventilator days, or length of stay between any of the interventions. Techniques of optimization of splanchnic perfusion and minimization of oxidant-mediated reperfusion injury evaluated in this study were not advantageous relative to standard resuscitation measures guided by conventional or tonometric measures of hypoperfusion in the therapy of occult and clinical shock in trauma patients.

Severity Scores

Achieving adequate perfusion is a key goal of treatment in severe trauma; however, tissue perfusion has classically been measured by indirect means. Direct visualization of capillary flow has been applied in sepsis, but application of this technology to the trauma population has been limited. The purpose of this investigation was to compare the efficacy of standard indirect measures of perfusion to direct imaging of the sublingual microcirculatory flow during trauma resuscitation. Patients with injury severity scores >15 were serially examined using a handheld sidestream dark-field video microscope. In addition, measurements were also made from healthy volunteers. The De Backer score, a morphometric capillary density score, and total vessel density (TVD) as cumulative vessel area within the image, were calculated using Automated Vascular Analysis (AVA3.0) software. These indices were compared against clinical and laboratory parameters of organ function and systemic metabolic status as well as mortality. Twenty severely injured patients had lower TVD (X = 14.6 ± 0.22 vs 17.66 ± 0.51) and De Backer scores (X = 9.62 ± 0.16 vs 11.55 ± 0.37) compared with healthy controls. These scores best correlated with serum lactate (TVD R2 = 0.525, De Backer R2 = 0.576, P < 0.05). Mean arterial pressure, heart rate, oxygen saturation, pH, bicarbonate, base deficit, hematocrit, and coagulation parameters correlated poorly with both TVD and De Backer score. Direct measurement of sublingual microvascular perfusion is technically feasible in trauma patients, and seems to provide real-time assessment of micro-circulatory perfusion. This study suggests that in severe trauma, many indirect measurements of perfusion do not correlate with microvascular perfusion. However, visualized perfusion deficiencies do reflect a shift toward anaerobic metabolism.

Abstract Purpose The number of severely injured patients exceeding the age of 60 has shown a steep increase within the last decades. These patients present with numerous co-morbidities, polypharmacy, and increased frailty requiring an adjusted treatment approach. In this study, we establish an overview of changes we observed in demographics of older severe trauma patients from 2002 to 2017. Methods A descriptive analysis of the data from the TraumaRegister DGU® (TR-DGU) was performed. Patients admitted to a level one trauma center in Germany, Austria and Switzerland between 2002 and 2017, aged 60 years or older and with an injury severity score (ISS) over 15 were included. Patients were stratified into subgroups based on the admission: 2002–2005 (1), 2006–2009 (2), 2010–2013 (3) and 2014–2017 (4). Trauma and patient characteristics, diagnostics, treatment and outcome were compared. Results In total 27,049 patients with an average age of 73.9 years met the inclusion criteria. The majority were males (64%), and the mean ISS was 27.4. The proportion of patients 60 years or older [(23% (1) to 40% (4)] rose considerably over time. Trauma mechanisms changed over time and more specifically low falls (< 3 m) rose from 17.6% (1) to 40.1% (4). Altered injury patterns were also identified. Length-of-stay decreased from 28.9 (1) to 19.5 days (4) and the length-of-stay on ICU decreased from 17.1 (1) to 12.7 days (4). Mortality decreased from 40.5% (1) to 31.8% (4). Conclusion Length of stay and mortality decreased despite an increase in patient age. We ascribe this observation mainly to increased use of diagnostic tools, improved treatment algorithms, and the implementation of specialized trauma centers for older patients allowing interdisciplinary care.

Objective. Pro-protein convertase subtilisin/kexin type 9 (PCSK9) is a circulating protein that impairs LDL clearance by promoting the LDL receptor (LDLR) degradation. Plasma lipid parameters (LDL-C and HDL-C) are related to severity of illness and survival in intensive care patients. Here, we aimed to determine whether circulating PCSK9 concentrations were correlated to the severity of illness in patients with multiple trauma. Methods/Results. Plasma PCSK9 were measured, at day 0 and 8 after admission, by ELISA in 111 patients hospitalized in ICU for severe trauma. Patients were included in the HIPOLYTE study and were randomly assigned to hydrocortisone therapy or placebo. Plasma PCSK9 levels were significantly increased by 161% at day 8 compared to day 0 (481 ± 227 vs 231 ± 117 ng/ml, P=0.0001). Hydrocortisone therapy did not alter PCSK9 concentrations at day 8 compared to placebo (451 ± 216 vs 511 ± 239ng/ml, P=0.33). In the whole population of the study, PCSK9 was positively associated with LDL-C (Pearson coefficient : 0.26, p=0.007) at day 0, but not with markers of severity illness. At day 8, an inverse correlation was found between PCSK9 and HDL-C (β =-653 ; P=0.004). Interestingly, PCSK9 concentrations at day 8 were related to markers of severity illness as injury severity score (β =6.17 ; P=0.0007), length of stay in ICU (β =6.14 ; P=0.0001), duration of both mechanical ventilation (β =8.26 ; P=0.0001) and cathecolamines infusion (β =18.57; P=0.015). Conclusion. PCSK9 appears as a late biomarker of severity illness in patients hospitalized for multiple trauma in ICU. These results open new perspectives for a role of PCSK9 in critical illness.

Racial Ethnic

Accumulating evidence suggests that reproductive potential and function may be different across racial and ethnic groups. Racial differences have been demonstrated in pubertal timing, infertility, outcomes after assisted reproductive technology (ART) treatment, and reproductive aging. Recently, racial differences have also been described in serum antimüllerian hormone (AMH), a sensitive biomarker of ovarian reserve, supporting the notion that ovarian reserve differs between racial/ethnic groups. The existence of such racial/ethnic differences in ovarian reserve, as reflected by AMH, may have important clinical implications for reproductive endocrinologists. However, the mechanisms which may underlie such racial differences in ovarian reserve are unclear. Various genetic factors and environmental factors such as obesity, smoking, and vitamin D deficiency which have been shown to correlate with serum AMH levels and also display significant racial/ethnic variations are discussed in this review. Improving our understanding of racial differences in ovarian reserve and their underlying causes may be essential for infertility treatment in minority women and lead to better reproductive planning, improved treatment outcomes, and timely interventions which may prolong reproductive lifespan in these women.

The purpose of this study was to determine the incidence of wound dehiscence after repeat trauma laparotomy. We performed a retrospective analysis of adult trauma patients who underwent laparotomy at an urban level 1 trauma center during the past 5 years. Patients were divided into single (SL) and multiple laparotomy (ML) groups. Demographic, clinical, and outcome data were collected. Data were analyzed using χ2, t testing, and ANOVA. Overall dehiscence rate was 0.7 per cent. Multiple laparotomy patients had damage control, staged management of their injuries, or abdominal compartment syndrome as the reason for reexploration. SL and ML patients had similar age and sex. ML patients had a higher rate of intra-abdominal abscess than SL patients (13.7% vs 1.2% P < 0.0001), but intra-abdominal abscess did not predict wound dehiscence in the ML group ( P = 0.24). This was true in spite of the fact that ML patients had a significantly higher Injury Severity Score (ISS) than SL patients (21.68 vs 14.35, P < 0.0001). Interestingly, wound infection did not predict dehiscence. Patients undergoing repeat laparotomy after trauma are at increased risk for wound dehiscence. This risk appears to be associated with intraabdominal abscess and ISS, but not wound infection. Surgeons should leave the skin open in the setting of repeat trauma laparotomy, which will allow serial assessment of the integrity of the fascial closure.

Stress Dose

Corticosteroids play an important role in responding to physiologic stress in the human body. However, its application in critical care remains heavily debated. The purpose of this study was to identify patient characteristics associated with receiving stress-dose steroids during the intensive care unit stay after traumatic injury and its effect on in-hospital mortality. Patients admitted to the University of Virginia trauma center between January 1, 2011, and December 31, 2015, were identified using our Trauma Registry. Stress dose steroids were defined as 100 mg IV hydrocortisone every eight hours. Patients who received stress-dose steroids were identified using the Clinical Data Repository. Patient characteristics associated with increased likelihood of receiving stress-dose steroids during admission were age >65, diabetes mellitus, congestive heart failure, burn injuries, Injury Severity Score >15, lower blood pressure (141/80 vs 125/76 mm Hg), and higher heart rate (87 vs 94/min). Patients who received stress-dose steroids were found to have increased mortality but not after controlling for the aforementioned patient factors associated with increased likelihood of receiving stress-dose steroids. The use of stress-dose steroids in critically ill patients with refractory hypotension does not appear to affect in-hospital mortality.

The Impact

It is commonly believed that the electronic medical record (EMR) will improve patient outcomes. However, there is scant published literature to support this claim and no studies in any surgical population. Our hypothesis was that the EMR would not improve objective outcome measures in patients with traumatic injury. Prospectively collected data from our university-based Level I trauma center was retrospectively reviewed. Demographic, injury severity as well as outcomes and complications data were compared for all patients admitted over a 20-month period before introduction of the EMR and a 20-month period after full, hospital-wide use of the EMR. Implementation of the EMR was associated with a decreased hospital length of stay, P = 0.02; intensive care unit length of stay, P = 0.001; ventilator days, P = 0.002; acute respiratory distress syndrome, P = 0.006, pneumonia, P = 0.008; myocardial infarction, P = 0.001; line infection, P = 0.03; septicemia, P = 0.000; renal failure, P = 0.000; drug complication, P = 0.001; and delay in diagnosis, P = 0.04. There was no difference in mortality, unexpected cardiac arrest, missed injury, pulmonary embolism/deep vein thrombosis, or late urinary tract infection. This is the first study to investigate the impact of the EMR in surgical patients. Although there was an improvement in some complications, the overall impact was inconsistent.

Multivariable Regression

Background Factors associated with delayed injury diagnosis (DID) have been examined, but incompletely researched. Methods We evaluated demographics, mechanism, and measures of mental status and injury severity among 10 years’ worth of adult trauma patients at our center for association with DID in a multivariable regression model. Descriptions of DID injuries were reviewed to highlight characteristics of these injuries. Results We included 13 509 patients, 89 (0.7%) of whom had a recognized DID. In regression analysis, ISS (OR 1.04 per point, 95% CI 1.02-1.06) and number of injuries (OR 1.08 per injury, 95% CI 1.04-1.11) were associated with DID. Operative patients had twice the odds of DID (OR 2.02, 95% CI 1.18-3.44). The most common category of DID was orthopedic extremity injury (22/89). Conclusion DID is associated with injury severity and operative intervention. This suggests that the presence of an injury requiring operation may distract the trauma team from additional injuries.

Racial And Ethnic Differences

Abstract Background Numerous studies have documented racial and ethnic differences in the prevalence and incidence of Alzheimer’s disease and related dementias (ADRD). Less is known, however, about racial and ethnic differences in health care expenditures among older adults at risk for ADRD (cognitive deficits without ADRD) or with ADRD. In particular, there is limited evidence that racial and ethnic differences in health care expenditures change over the trajectory of ADRD or differ by types of service. Methods We examined racial and ethnic patterns and differences in health care expenditures (total health care expenditures, out-of-pocket expenditures, and six service-specific expenditures) among Medicare beneficiaries without cognitive deficits, those with cognitive deficits without ADRD, and those with ADRD. Using the 1996–2017 Medical Expenditure Panel Survey, we performed multivariable regression models to estimate expenditure differences among racial and ethnic groups without cognitive deficits, those with cognitive deficits without ADRD, and those with ADRD. Models accounted for survey weights and adjusted for various demographic, socioeconomic, and health characteristics. Results Black, Asians, and Latinos without cognitive deficits had lower total health care expenditures than whites without cognitive deficits ($10,236, $9497, $9597, and $11,541, respectively). There were no racial and ethnic differences in total health care expenditures among those with cognitive deficits without ADRD and those with ADRD. Across all three groups, however, Blacks, Asians, and Latinos consistently had lower out-of-pocket expenditures than whites (except for Asians with cognitive deficits without ADRD). Furthermore, service-specific health care expenditures varied by racial and ethnic groups. Conclusions Our study did not find significant racial and ethnic differences in total health care expenditures among Medicare beneficiaries with cognitive deficits and/or ADRD. However, we documented significant differences in out-of-pocket expenditures and service-specific expenditures. We speculated that the differences may be attributable to racial and ethnic differences in access to care and/or preferences based on family structure and cultural/economic factors. Particularly, heterogeneous patterns of service-specific expenditures by racial and ethnic groups underscore the importance of future research in identifying determinants leading to variations in service-specific expenditures among racial and ethnic groups.
