Acceptability of a hypothetical dengue vaccine and the potential impact of dengue vaccination on personal vector control behavior: a qualitative study in Fortaleza, Brazil.

BACKGROUND: Dengue is the most rapidly spreading viral vector-borne disease in the world. Promising new dengue vaccines have contributed to a growing consensus that effective dengue control will require integrated strategies of vaccination and vector control. In this qualitative study, we explored the perspectives of residents of Fortaleza, Brazil on acceptability of a hypothetical safe and effective dengue vaccine, specific drivers of dengue vaccine acceptance or hesitance, and the expected impact of dengue vaccination on their personal vector control practices. METHODS: A total of 43 in-depth interviews were conducted from April to June 2022 with Fortaleza residents from a diverse range of educational and professional backgrounds, with and without recent personal experiences of symptomatic dengue infections. Data were analyzed using the principles of inductive grounded theory methodology. RESULTS: Our findings indicate that knowledge of dengue transmission, symptoms, and prevention methods was strong across respondents. Respondents described willingness to accept a hypothetical dengue vaccine for themselves and their children, while emphasizing that the vaccine must be demonstrably safe and effective. Respondents expressed diverse perspectives on how receiving a safe and effective dengue vaccine might influence their personal vector control behaviors, relating these behaviors to their perception of risk from other Aedes mosquito-carried infections and beliefs about the role of vector control in maintaining household cleanliness. CONCLUSIONS: Our study findings provide community-level perspectives on dengue vaccination and its potential impact on personal vector control behavior for policymakers and program managers in Fortaleza to consider as new dengue vaccines become available. With the introduction of any new dengue vaccine, community perspectives and emerging concerns that may drive vaccine hesitancy should be continuously sought out. Improved urban infrastructure and efforts to engage individuals and communities in vector control may be needed to optimize the impact of future dengue vaccinations and prevent rising cases of other arboviruses such as Zika and chikungunya.

Expanding access to parasite-based malaria diagnosis through retail drug shops in Tanzania: evidence from a randomized trial and implications for treatment.

BACKGROUND: Tanzania has seen a reduction in the fraction of fevers caused by malaria, likely due in part to scale-up of control measures. While national guidelines require parasite-based diagnosis prior to treatment, it is estimated that more than half of suspected malaria treatment-seeking in Tanzania initiates in the private retail sector, where diagnosis by malaria rapid diagnostic test (RDT) or microscopy is illegal. This pilot study investigated whether the introduction of RDTs into Accredited Drug Dispensing Outlets (ADDOs) under realistic market conditions would improve case management practices. METHODS: Dispensers from ADDOs in two intervention districts in Tanzania were trained to stock and perform RDTs and monitored quarterly. Each district was assigned a different recommended retail price to evaluate the need for a subsidy. Malaria RDT and artemisinin-based combination therapy (ACT) uptake and availability were measured pre-intervention and 1 year post-intervention through structured surveys of ADDO owners and exiting customers in both intervention districts and one contiguous control district. Descriptive analysis and logistic regression were used to compare the three districts and identify predictive variables for testing. RESULTS AND DISCUSSION: A total of 310 dispensers from 262 ADDOs were trained to stock and perform RDTs. RDT availability in intervention ADDOs increased from 1% (n = 172) to 73% (n = 163) during the study; ACT medicines were available in 75% of 260 pre-intervention and 68% of 254 post-intervention ADDOs. Pre-treatment testing performed within the ADDO increased from 0 to 65% of suspected malaria patients who visited a shop (95% CI 60.8-69.6%) with no difference between intervention districts. Overall parasite-based diagnosis increased from 19 to 74% in intervention districts and from 3 to 18% in the control district. Prior knowledge of RDT availability (aOR = 1.9, p = 0.03) and RDT experience (aOR = 1.9, p = 0.01) were predictors for testing. Adherence data indicated that 75% of malaria positives received ACT, while 3% of negatives received ACT. CONCLUSIONS: Trained and supervised ADDO dispensers in rural Tanzania performed and sold RDTs under real market conditions to two-thirds of suspected malaria patients during this one-year pilot. These results support the hypothesis that introducing RDTs into regulated private retail sector settings can improve malaria testing and treatment practices without an RDT subsidy.

The hazards of off-road motor sports: Are four wheels better than two?

BACKGROUND: Off-road motorsports are an increasing popular activity, yet the relative safety profile of all-terrain vehicles (ATV) to off-road motorcycles (ORMC) has not been compared. STUDY DESIGN: A retrospective review of the 2002-2006 US National Trauma Data Bank of ATV and ORMC crash victims. Patients were described according to demographic (age, sex, race and ethnicity, insurance status) and injury characteristics (Injury Severity Score, hypotension, motor component of the Glasgow Coma Score, presence of a severe head or extremity injury) known to affect trauma outcomes. Logistic regression evaluated the independent effect of an ATV vehicle on mortality, intensive care unit (ICU) admission, and placement on a ventilator relative to ORMC. The anatomic distribution of severe injuries was compared between survivors and decedents within each vehicle type. RESULTS: A total of 34,457 patients met inclusion criteria, of whom, 24,582 were ATV patients and 9875 were ORMC patients. ATV patients had 51% higher risk-adjusted odds of death (OR 1.51; 95% CI 1.03-2.20), 55% higher risk-adjusted odds of being admitted to an ICU (OR 1.55; 95% CI 1.42-1.70), and 42% higher risk-adjusted odds of being placed on a ventilator (OR 1.42, 95% CI 1.17-1.72) compared to ORMC crash victims. Decedents in both vehicle types were more likely to suffer severe head, thoracic, and abdominal injuries relative to their surviving counterparts. CONCLUSION: For injured riders, ATVs are associated with increased mortality and higher resource utilisation compared to ORMCs. Both groups suffer distinct anatomic injuries, suggesting the need for focused areas of injury prevention planning and research.

Community Health Workers' Provision of Family Planning Services in Low- and Middle-Income Countries: A Systematic Review of Effectiveness.

This systematic review evaluates the strength of the evidence that community health workers' (CHW) provision of family planning (FP) services in low- and middle-income countries is effective. In a search of eight databases, articles were screened by study design and outcome measure and ranked by strength of evidence. Only randomized trials, longitudinal studies with a comparison group, and pre-test/post-test studies met inclusion criteria. A total of 56 studies were included. Of those studies with relevant data, approximately 93 percent indicated that CHW FP programs effectively increased the use of modern contraception, while 83 percent reported an improvement in knowledge and attitudes concerning contraceptives. Based on these findings, strong evidence exists for promoting CHW programs to improve access to FP services. We recommend a set of best practice guidelines that researchers and program managers can use to report on CHW FP programs to facilitate the translation of research to practice across a wide range of settings.

Unconscious Race and Class Biases among Registered Nurses: Vignette-Based Study Using Implicit Association Testing.

BACKGROUND: Implicit bias is an unconscious preference for a specific social group that can have adverse consequences for patient care. Acute care clinical vignettes were used to examine whether implicit race or class biases among registered nurses (RNs) impacted patient-management decisions. STUDY DESIGN: In a prospective study conducted among surgical RNs at the Johns Hopkins Hospital, participants were presented 8 multi-stage clinical vignettes in which patients' race or social class were randomly altered. Registered nurses were administered implicit association tests (IATs) for social class and race. Ordered logistic regression was then used to examine associations among treatment differences, race, or social class, and RN's IAT scores. Spearman's rank coefficients comparing RN's implicit (IAT) and explicit (stated) preferences were also investigated. RESULTS: Two hundred and forty-five RNs participated. The majority were female (n=217 [88.5%]) and white (n=203 [82.9%]). Most reported that they had no explicit race or class preferences (n=174 [71.0%] and n=108 [44.1%], respectively). However, only 36 nurses (14.7%) demonstrated no implicit race preference as measured by race IAT, and only 16 nurses (6.53%) displayed no implicit class preference on the class IAT. Implicit association tests scores did not statistically correlate with vignette-based clinical decision making. Spearman's rank coefficients comparing implicit (IAT) and explicit preferences also demonstrated no statistically significant correlation (r=-0.06; p=0.340 and r=-0.06; p=0.342, respectively). CONCLUSIONS: The majority of RNs displayed implicit preferences toward white race and upper social class patients on IAT assessment. However, unlike published data on physicians, implicit biases among RNs did not correlate with clinical decision making.

Outcomes of trauma care at centers treating a higher proportion of older patients: the case for geriatric trauma centers.

BACKGROUND: The burden of injury among older patients continues to grow and accounts for a disproportionate number of trauma deaths. We wished to determine if older trauma patients have better outcomes at centers that manage a higher proportion of older trauma patients. METHODS: The National Trauma Data Bank years 2007 to 2011 was used. All high-volume Level 1 and Level 2 trauma centers were included. Trauma centers were categorized by the proportion of older patients seen. Adult trauma patients were categorized as older (≥65 years) and younger adults (16-64 years). Coarsened exact matching was used to determine differences in mortality and length of stay between older and younger adults. Risk-adjusted mortality ratios by proportion of older trauma patients seen were analyzed using multivariate logistic regression models and observed-expected ratios. RESULTS: A total of 1.9 million patients from 295 centers were included. Older patients accounted for one fourth of trauma visits. Matched analysis revealed that older trauma patients were 4.2 times (95% confidence interval, 3.99-4.50) more likely to die than younger patients. Older patients were 34% less likely to die if they presented at centers treating a high versus low proportion of older trauma (odds ratio, 0.66; 95% confidence interval, 0.54-0.81). These differences were independent of trauma center performance. CONCLUSION: Geriatric trauma patients treated at centers that manage a higher proportion of older patients have improved outcomes. This evidence supports the potential advantage of treating older trauma patients at centers specializing in geriatric trauma. LEVEL OF EVIDENCE: Prognostic and epidemiologic study, level III.

Unconscious race and social class bias among acute care surgical clinicians and clinical treatment decisions.

IMPORTANCE: Significant health inequities persist among minority and socially disadvantaged patients. Better understanding of how unconscious biases affect clinical decision making may help to illuminate clinicians' roles in propagating disparities. OBJECTIVE: To determine whether clinicians' unconscious race and/or social class biases correlate with patient management decisions. DESIGN, SETTING, AND PARTICIPANTS: We conducted a web-based survey among 230 physicians from surgery and related specialties at an academic, level I trauma center from December 1, 2011, through January 31, 2012. INTERVENTIONS: We administered clinical vignettes, each with 3 management questions. Eight vignettes assessed the relationship between unconscious bias and clinical decision making. We performed ordered logistic regression analysis on the Implicit Association Test (IAT) scores and used multivariable analysis to determine whether implicit bias was associated with the vignette responses. MAIN OUTCOMES AND MEASURES: Differential response times (D scores) on the IAT as a surrogate for unconscious bias. Patient management vignettes varied by patient race or social class. Resulting D scores were calculated for each management decision. RESULTS: In total, 215 clinicians were included and consisted of 74 attending surgeons, 32 fellows, 86 residents, 19 interns, and 4 physicians with an undetermined level of education. Specialties included surgery (32.1%), anesthesia (18.1%), emergency medicine (18.1%), orthopedics (7.9%), otolaryngology (7.0%), neurosurgery (7.0%), critical care (6.0%), and urology (2.8%); 1.9% did not report a departmental affiliation. Implicit race and social class biases were present in most respondents. Among all clinicians, mean IAT D scores for race and social class were 0.42 (95% CI, 0.37-0.48) and 0.71 (95% CI, 0.65-0.78), respectively. Race and class scores were similar across departments (general surgery, orthopedics, urology, etc), race, or age. Women demonstrated less bias concerning race (mean IAT D score, 0.39 [95% CI, 0.29-0.49]) and social class (mean IAT D score, 0.66 [95% CI, 0.57-0.75]) relative to men (mean IAT D scores, 0.44 [95% CI, 0.37-0.52] and 0.82 [95% CI, 0.75-0.89], respectively). In univariate analyses, we found an association between race/social class bias and 3 of 27 possible patient-care decisions. Multivariable analyses revealed no association between the IAT D scores and vignette-based clinical assessments. CONCLUSIONS AND RELEVANCE: Unconscious social class and race biases were not significantly associated with clinical decision making among acute care surgical clinicians. Further studies involving real physician-patient interactions may be warranted.

Incremental Cost of Emergency Versus Elective Surgery.

OBJECTIVE: To determine hospital costs and the adjusted risk of death associated with emergent versus elective surgery. BACKGROUND: Emergency surgery has a higher cost and worse outcomes compared with elective surgery. However, no national estimates of the excess burden of emergency surgery exist. METHODS: Nationwide Inpatient Sample (NIS) data from 2001 to 2010 were analyzed. Patients aged 18 years or older who underwent abdominal aortic aneurysm repair, coronary artery bypass graft, or colon resection for neoplasm were included. Using generalized linear models with propensity scores, cost differences for emergent versus elective admission were calculated for each procedure. Multivariable logistic regression was performed to investigate the adjusted odds of mortality comparing elective and emergent cases. Discharge-level weights were applied to analyses. RESULTS: A total of 621,925 patients, representing a weighted population of 3,057,443, were included. The adjusted mean cost difference for emergent versus elective care was $8741.22 (30% increase) for abdominal aortic aneurysm repair, $5309.78 (17% increase) for coronary artery bypass graft, and $7813.53 (53% increase) for colon resection. If 10% of the weighted estimates of emergency procedures had been performed electively, the cost benefit would have been nearly $1 billion, at $996,169,160 (95% confidence interval [CI], $985,505,565-$1,006,834,104). Elective surgery patients had significantly lower adjusted odds of mortality for all procedures. CONCLUSIONS: Even a modest reduction in the proportion of emergent procedures for 3 conditions is estimated to save nearly $1 billion over 10 years. Preventing emergency surgery through improved care coordination and screening offers a tremendous opportunity to save lives and decrease costs.

Unconscious race and class bias: its association with decision making by trauma and acute care surgeons.

BACKGROUND: Recent studies have found that unconscious biases may influence physicians' clinical decision making. The objective of our study was to determine, using clinical vignettes, if unconscious race and class biases exist specifically among trauma/acute care surgeons and, if so, whether those biases impact surgeons' clinical decision making. METHODS: A prospective Web-based survey was administered to active members of the Eastern Association for the Surgery of Trauma. Participants completed nine clinical vignettes, each with three trauma/acute care surgery management questions. Race Implicit Association Test (IAT) and social class IAT assessments were completed by each participant. Multivariable, ordered logistic regression analysis was then used to determine whether implicit biases reflected on the IAT tests were associated with vignette responses. RESULTS: In total, 248 members of the Eastern Association for the Surgery of Trauma participated. Of these, 79% explicitly stated that they had no race preferences and 55% stated they had no social class preferences. However, 73.5% of the participants had IAT scores demonstrating an unconscious preference toward white persons; 90.7% demonstrated an implicit preference toward upper social class persons. Only 2 of 27 vignette-based clinical decisions were associated with patient race or social class on univariate analyses. Multivariable analyses revealed no relationship between IAT scores and vignette-based clinical assessments. CONCLUSION: Unconscious preferences for white and upper-class persons are prevalent among trauma and acute care surgeons. In this study, these biases were not statistically significantly associated with clinical decision making. Further study of the factors that may prevent implicit biases from influencing patient management is warranted. LEVEL OF EVIDENCE: Epidemiologic study, level II.

Association between intentional injury and long-term survival after trauma.

OBJECTIVE: To determine the risk-adjusted mortality of intentionally injured patients within 7 to 9 years postinjury, compared with unintentionally injured patients. BACKGROUND: Violent injury contributes significantly to trauma mortality in the United States. Homicide is the second leading killer of American youth, aged 15 to 24 years. Long-term survival among intentionally injured patients has not been well studied. It is also unknown whether intentionally injured patients have worse long-term survival compared with unintentionally or accidentally injured patients with equivalent injuries. METHODS: Adult trauma patients admitted for 24 hours or more and discharged alive from the Johns Hopkins Hospital from January 1, 1998, to December 31, 2000, were included. The primary outcome was mortality within 7 to 9 years postinjury. Long-term patient survival was determined using the National Death Index. The association between injury intentionality and mortality was investigated using a Cox proportional hazard regression model, adjusted for confounders such as injury severity and patient race, socioeconomic status, and comorbid conditions. Overall differences in survival between those with intentional versus unintentional injury were also determined by comparing adjusted Kaplan-Meier survival curves. RESULTS: A total of 2062 patients met inclusion criteria. Of these, 56.4% were intentionally injured and 43.6% were unintentionally injured. Compared with unintentionally injured patients, intentionally injured patients were younger and more often male and from a zip code with low median household income. Approximately 15% of all patients had died within 7 to 9 years of follow-up. Older age and presence of comorbidities were associated with this outcome; however, intentional injury was not found to be significantly associated with long-term mortality rates. There was also no significant difference in survival curves between groups; intentionally injured patients were much more likely to die of a subsequent injury, whereas those with unintentional injury commonly died of noninjury causes. CONCLUSIONS: There was no significant difference in mortality between intentionally injured and unintentionally injured patients within 7 to 9 years postinjury. These results confirm the long-term effectiveness of lifesaving trauma care for those with intentional injury. However, given that patients with intentional injuries were more likely to suffer a subsequent violent death, interventions focused on breaking the cycle of violence are needed.

Socioeconomic disparity in inpatient mortality after traumatic injury in adults.

BACKGROUND: Prior studies have demonstrated that race and insurance status predict inpatient trauma mortality, but have been limited by their inability to adjust for direct measures of socioeconomic status (SES) and comorbidities. Our study aimed to identify whether a relationship exists between SES and inpatient trauma mortality after adjusting for known confounders. METHODS: Trauma patients aged 18-65 years with an Injury Severity Scores (ISS) of ≥9 were identified using the 2003-2009 Nationwide Inpatient Sample. Median household income (MHI) by zip code, available by quartiles, was used to measure SES. Multiple logistic regression analyses were performed to determine odds of inpatient mortality by MHI quartile, adjusting for ISS, type of injury, comorbidities, and patient demographics. RESULTS: In all, 267,621 patients met inclusion criteria. Patients in lower wealth quartiles had significantly greater unadjusted inpatient mortality compared with the wealthiest quartile. Adjusted odds of death were also higher compared with the wealthiest quartile for Q1 (odds ratio [OR], 1.13; 95% confidence interval [CI], 1.06-1.20), Q2 (OR, 1.09; 95% CI, 1.02-1.17), and Q3 (OR, 1.11; 95% CI, 1.04-1.19). CONCLUSION: MHI predicts inpatient mortality after adult trauma, even after adjusting for race, insurance status, and comorbidities. Efforts to mitigate trauma disparities should address SES as an independent predictor of outcomes.

Increased complications after appendectomy in patients with cerebral palsy: are special needs patients at risk for disparities in outcomes?

BACKGROUND: Cerebral palsy (CP) is a nonprogressive neurologic disorder. Anecdotal evidence suggests there are worse outcomes in this population after common operative procedures like appendectomy. This study aims to classify whether there are relevant disparities in postoperative outcomes in CP versus non-CP patients after open or laparoscopic appendectomy. METHODS: Hospital discharge data from the 2003-2009 weighted Nationwide Inpatient Sample were used. Unadjusted and adjusted multiple logistic regression were used to assess postoperative complications, as well as inpatient mortality, average duration of hospital stay, and cost. RESULTS: Approximately 1,250 patients with CP met the inclusion criteria. After adjusted analysis, CP patients displayed significantly greater odds of the following postoperative complications: Sepsis/organ failure, operation-related infection, pneumonia, urinary tract infection, and acute respiratory distress syndrome. Patients with CP also had a greater cost and in-hospital stay after appendectomy. CONCLUSION: Patients with CP have greater adjusted odds of complications after open or laparoscopic appendectomy. The mechanisms that led to these disparities need to be studied and may include difficulties in patient assessment and communication. Additional education of healthcare providers to improve recognition of symptoms and care for patients with disabilities may be more immediately helpful in decreasing disparities in outcomes.

Counting the lives lost: how many black trauma deaths are attributable to disparities?

BACKGROUND: The number of black trauma deaths attributable to racial disparities is unknown. The objective of this study was to quantify the excess mortality experienced by black patients given disparities in the risk of mortality. MATERIALS AND METHODS: We performed a retrospective analysis of patients aged 16-65 y with blunt and penetrating injuries, who were included in the National Trauma Data Bank from 2007-2010. Generalized linear modeling estimated the relative risk of death for black patients versus white patients, adjusting for known confounders. This analysis determined the difference in the observed number of black trauma deaths at Level I and II centers and the expected number of deaths if the risk of mortality for black patients had been equivalent to that of white patients. RESULTS: A total of 1.06 million patients were included. Among patients with blunt and penetrating injuries at Level I trauma centers, white males and females had a relative risk of death of 0.82 (95% confidence interval [CI], 0.80-0.85) and 0.78 (95% CI, 0.74-0.83), respectively, compared with black patients. Similarly, at Level II trauma centers, white males and females had a relative risk of death of 0.84 (95% CI, 0.80-0.88) and 0.82 (95% CI, 0.73-0.91). Overall, of the estimated 41,613 deaths that occurred at Level I and II centers, 2206 (5.3%) were excess deaths among black patients. CONCLUSIONS: Over a 4-y period, approximately 5% of trauma center deaths could be attributed to racial disparities in trauma outcomes. These data underscore the need to better understand and intervene against the mechanisms that lead to trauma outcomes disparities.

Increased risk of pneumonia among ventilated patients with traumatic brain injury: every day counts!

BACKGROUND: Patients with traumatic brain injury (TBI) frequently require mechanical ventilation (MV). The objective of this study was to examine the association between time spent on MV and the development of pneumonia among patients with TBI. MATERIALS AND METHODS: Patients older than 18 y with head abbreviated injury scale (AIS) scores coded 1-6 requiring MV in the National Trauma Data Bank 2007-2010 data set were included. The study was limited to hospitals reporting pneumonia cases. AIS scores were calculated using ICDMAP-90 software. Patients with injuries in any other region with AIS score >3, significant burns, or a hospital length of stay >30 d were excluded. A generalized linear model was used to determine the approximate relative risk of developing all-cause pneumonia (aspiration pneumonia, ventilator-associated pneumonia [VAP], and infectious pneumonia identified by the International Classification of Disease, Ninth Revision, diagnosis code) for each day of MV, controlling for age, gender, Glasgow coma scale motor score, comorbidity (Charlson comorbidity index) score, insurance status, and injury type and severity. RESULTS: Among the 24,525 patients with TBI who required MV included in this study, 1593 (6.5%) developed all-cause pneumonia. After controlling for demographic and injury factors, each additional day on the ventilator was associated with a 7% increase in the risk of pneumonia (risk ratio 1.07, 95% confidence interval 1.07-1.08). CONCLUSIONS: Patients who have sustained TBIs and require MV are at higher risk for VAP than individuals extubated earlier; therefore, shortening MV exposure will likely reduce the risk of VAP. As patients with TBI frequently require MV because of neurologic impairment, it is key to develop aggressive strategies to expedite ventilator independence.

National cost of trauma care by payer status.

BACKGROUND: Several studies have described the burden of trauma care, but few have explored the economic burden of trauma inpatient costs from a payer's perspective or highlighted the differences in the average costs per person by payer status. The present study provides a conservative inpatient national trauma cost estimate and describes the variation in average inpatient trauma cost by payer status. METHODS: A retrospective analysis of patients who had received trauma care at hospitals in the Nationwide Inpatient Sample from 2005-2010 was conducted. Our sample patients were selected using the appropriate "International Classification of Diseases, Ninth Revision, Clinical Modification" codes to identify admissions due to traumatic injury. The data were weighted to provide national population estimates, and all cost and charges were converted to 2010 US dollar equivalents. Generalized linear models were used to describe the costs by payer status, adjusting for patient characteristics, such as age, gender, and race, and hospital characteristics, such as location, teaching status, and patient case mix. RESULTS: A total of 2,542,551 patients were eligible for the present study, with the payer status as follows: 672,960 patients (26.47%) with private insurance, 1,244,817 (48.96%) with Medicare, 262,256 (10.31%) with Medicaid, 195,056 (7.67%) with self-pay, 18,506 (0.73%) with no charge, and 150,956 (5.94%) with other types of insurance. The estimated yearly trauma inpatient cost burden was highest for Medicare at $17,551,393,082 (46.79%), followed by private insurance ($10,772,025,421 [28.72%]), Medicaid ($3,711,686,012 [9.89%], self-pay ($2,831,438,460 [7.55%]), and other payer types ($2,370,187,494 [6.32%]. The estimated yearly trauma inpatient cost burden was $274,598,190 (0.73%) for patients who were not charged for their inpatient trauma treatment. Our adjusted national inpatient trauma yearly costs were estimated at $37,511,328,659 US dollars. Privately insured patients had a significantly higher mean cost per person than did the Medicare, Medicaid, self-pay, or no charge patients. CONCLUSIONS: The results of the present study have demonstrated that the distribution of trauma burden across payers is significantly different from that of the overall healthcare system and suggest that although the burden of trauma is high, the burden of self-pay or nonreimbursed inpatient services is actually lower than that of overall medical care.

Association between hospitals caring for a disproportionately high percentage of minority trauma patients and increased mortality: a nationwide analysis of 434 hospitals.

OBJECTIVE: To determine whether there is an increased odds of mortality among trauma patients treated at hospitals with higher proportions of minority patients (ie, black and Hispanic patients combined). DESIGN: Hospitals were categorized on the basis of the percentage of minority patients admitted with trauma. The adjusted odds of in-hospital mortality were compared between hospitals with less than 25% of patients who were minorities (the reference group) and hospitals with 25% to 50% of patients who were minorities and hospitals with more than 50% of patients who were minorities. Multivariate logistic regression (with generalized linear modeling and a cluster-correlated robust estimate of variance) was used to control for multiple patient and injury severity characteristics. SETTING: A total of 434 hospitals in the National Trauma Data Bank. PARTICIPANTS: Patients aged 18 to 64 years whose medical records were included in the National Trauma Data Bank for the years 2007 and 2008 with an Injury Severity Score of 9 or greater and who were white, black, or Hispanic. MAIN OUTCOME MEASURES: Crude mortality and adjusted odds of in-hospital mortality. RESULTS: A total of 311,568 patients were examined. Hospitals in which the percentage of minority patients was more than 50% also had younger patients, fewer female patients, more patients with penetrating trauma, and the highest crude mortality. After adjustment for potential confounders, patients treated at hospitals in which the percentage of minority patients was 25% to 50% and at hospitals in which the percentage of minority patients was more than 50% demonstrated increased odds of death (adjusted odds ratio, 1.16 [95% confidence interval, 1.01-1.34] and adjusted odds ratio, 1.37 [95% confidence interval, 1.16-1.61], respectively), compared with the reference group. This disparity increased further on subset analysis of patients with a blunt injury. Uninsured patients had significantly increased odds of mortality within all 3 hospital groups. CONCLUSIONS: Patients treated at hospitals with higher proportions of minority trauma patients have increased odds of dying, even after adjusting for potential confounders. Differences in outcomes between trauma hospitals may partly explain racial disparities.
