Ontology highlight
ABSTRACT: Importance
Trauma centers improve outcomes for young patients with serious injuries. However, most injury-related hospital admissions and deaths occur in older adults, and it is not clear whether trauma center care provides the same benefit in this population.Objective
To examine whether 30- and 365-day mortality of injured older adults is associated with the treating hospital's trauma center level.Design, setting, and participants
This prospective, population-based cohort study used Medicare claims data from January 1, 2013, to December 31, 2016, for all fee-for-service Medicare beneficiaries 66 years or older with inpatient admission for traumatic injury in 2014 to 2015. Data analysis was performed from January 1 to June 31, 2021. Preinjury health was measured using 2013 claims, and outcomes were measured through 2016. The population was stratified by anatomical injury pattern. Propensity scores for level I trauma center treatment were estimated using the Abbreviated Injury Scale, age, and residential proximity to trauma center and then used to match beneficiaries from each trauma level (I, II, III, and IV/non-trauma centers) by injury type.Exposure
Admitting hospital's trauma center level.Main outcomes and measures
Case fatality rates (CFRs) at 30 and 365 days after injury, estimated in the matched sample using multivariable, hierarchical logistic regression models.Results
A total of 433 169 Medicare beneficiaries (mean [SD] age, 82.9 [8.3] years; 68.4% female; 91.5% White) were included in the analysis. A total of 206 275 (47.6%) were admitted to non-trauma centers and 161 492 (37.3%) to level I or II trauma centers. Patients with isolated extremity fracture had the fewest deaths (365-day CFR ranged from 16.1% [95% CI, 11.2%-22.4%] to 17.4% [95% CI, 11.8%-24.6%] by trauma center status). Patients with both hip fracture and traumatic brain injury had the most deaths (365-day CFRs ranged from 33.4% [95% CI, 25.8%-42.1%] to 35.8% [95% CI, 28.9%-43.5%]).Conclusions and relevance
These findings suggest that older adults do not benefit from existing trauma center care, which is designed with younger patients in mind. There is a critical need to improve trauma care practices to address common injury mechanisms and types of injury in older adults.

Project description:Falls are common and associated with adverse outcomes in patients on dialysis. Limited data are available in earlier stages of CKD.We analyzed data from 8744 Reasons for Geographic and Racial Differences in Stroke Study participants ?65 years old with Medicare fee for service coverage. Serious fall injuries were defined as a fall-related fracture, brain injury, or joint dislocation using Medicare claims. Hazard ratios (HRs) for serious fall injuries were calculated by eGFR and albumin-to-creatinine ratio (ACR). Among 2590 participants with CKD (eGFR<60 ml/min per 1.73 m(2) or ACR?30 mg/g), cumulative mortality after a serious fall injury compared with age-matched controls without a fall injury was calculated.Overall, 1103 (12.6%) participants had a serious fall injury over 9.9 years of follow-up. The incidence rates per 1000 person-years of serious fall injuries were 21.7 (95% confidence interval [95% CI], 20.3 to 23.2), 26.6 (95% CI, 22.6 to 31.3), and 38.3 (95% CI, 31.2 to 47.0) at eGFR levels ?60, 45-59, and <45 ml/min per 1.73 m(2), respectively, and 21.3 (95% CI, 20.0 to 22.8), 31.7 (95% CI, 27.5 to 36.5), and 42.2 (95% CI, 31.3 to 56.9) at ACR levels <30, 30-299, and ?300 mg/g, respectively. Multivariable adjusted HRs for serious fall injuries were 0.91 (95% CI, 0.76 to 1.09) and 1.09 (95% CI, 0.86 to 1.37) for eGFR=45-59 and <45 ml/min per 1.73 m(2), respectively, versus eGFR?60 ml/min per 1.73 m(2) and 1.31 (95% CI, 1.11 to 1.54) and 1.81 (95% CI, 1.30 to 2.50) for ACR=30-299 and ?300 mg/g, respectively, versus ACR<30 mg/g. Among participants with CKD, cumulative 1-year mortality rates among patients with a serious fall and age-matched controls were 21.0% and 5.5%, respectively.Elevated ACR but not lower eGFR was associated with serious fall injuries. Evaluation for fall risk factors and fall prevention strategies should be considered for older adults with elevated ACR.

Project description:ObjectiveTo examine sociodemographic predictors of trauma center (TC) transport of severely injured older adults.Data sourcesThe data source was the Healthcare Cost and Utilization Project, New York Inpatient Database (2014).Study designThis study was a secondary analysis of injured older adults. Key sociodemographic variables were age, gender, race/ethnicity, median household income, and primary payer. Confounding variables were injury severity, geographic location, number of chronic conditions, and injury mechanism. The outcome variable was TC transport.Data collection/extraction methodsThe database was filtered on the following criteria: age =/> 55 years, primary diagnosis of injury (International Classification of Diseases, 9th Revision, Clinical Modification [ICD-9-CM], 800.0-957.9, excluding poisoning, late effects, and interfacility transfers), admitted to an acute care hospital in New York.Principal findingsRecords of 33 696 patients were included. Multivariate logistic regression analysis revealed that all variables were statistically significant predictors of TC transport except primary payer. Predictors of TC transport were as follows: higher injury severity (OR 2.1, CI 1.79-2.46; 3.39, CI 2.85-4.05); Asian/Pacific and Hispanic race/ethnicity (OR 2.51, CI 1.92-3.27; OR 1.1, CI 0.86-1.42), highest median household income (OR 1.24, CI 1.01-1.52), high population density (OR 1.32, CI 1.12-1.55; OR 3.2, CI 2.68-2.83), and vehicle crashes (OR 3.39, CI 2.79-4.11). Predictors of non-TC transport were as follows: older age groups (OR 0.92, CI 0.76-1.11; OR 0.79, CI 0.64-0.96; OR 0.77, CI 0.63-0.95), females (OR 0.65, CI 0.57-0.74), Black and "other" race (OR 0.75, CI 0.0.56-1.0; OR 0.96, CI 0.77-1.20), lower median household income (OR 0.76, CI 0.62-0.93; OR 0.86, CI 0.71-1.05), low population density (OR 0.96, CI 0.67-1.36; OR 0.89, CI 0.53-1.51), and number of chronic conditions (OR 0.89, CI 0.87-0.91).ConclusionsSociodemographic factors are a source of disparity for access to TCs. Further research is needed to confirm bias and test bias reduction strategies. Comprehensive education and policies are needed to reduce disparities in access to trauma care.

Project description:Purpose:This study was conducted to investigate the relationships between arterial stiffness, frailty and fall-related injuries among community-dwelling older adults. Materials and Methods:A cross-sectional study of a random sample of older adults aged 60 years and older was conducted. Main study parameters: arterial stiffness was measured by the determining the cardio-ankle vascular index (CAVI); Frailty status was defined using a 7-item frailty screening scale, developed in Russia. This questionnaire included question about falls and fall-related injuries. Orthostatic test and anthropometric tests were done. Medical history (comorbidity, medications), the Osteoporosis Self-assessment Tool (OST), nutritional, physical, cognitive and functional status were evaluated. Results:The study population included 163 people aged 60-89 years. The average predicted value of CAVI in women aged 60-69 was 9.13 ± 0.13, in men, 9.49 ± 0.05; in women aged 70-79, it was 9.49 ± 0.16, in men, 9.73 ±0.11; in women aged 80 and older it was 10.04 ±0.18, in men, 10.24 ±0.10 units. The CAVI above the predicted value was associated with fall-related injuries even after adjustment for age, sex, use of ?-blockers (BBs), history of stroke, and region of residence with the odds ratio 3.52 (95% CI: 1.03 -12.04). Conclusion:Our study revealed an independent association between arterial stiffness and fall-related injuries in older adults over 60 years. The findings suggest that clinicians, especially geriatricians, should pay attention to arterial stiffness of patients with fall-related injuries. Similarly, the patients with CAVI above age-predicted value should be evaluated for risk of falls for prevention of fall-related injuries.

Project description:BackgroundMangled extremities are one of the most difficult injuries for trauma surgeons to manage. We compare limb salvage rates for a limb-threatening lower extremity injuries managed at Level I vs Level II trauma centers (TCs).Study designWe identified all adult patients with a limb-threatening injury who underwent primary amputation or limb salvage (LS) using the American College of Surgeons (ACS) Trauma Quality Improvement Program database at ACS Level I vs II TCs between 2007 and 2017. A limb-threatening injury was defined as an open tibial fracture with concurrent arterial injury (Gustilo type IIIc). Multivariable analysis and propensity score matching were performed to minimize confounding by indication.ResultsThere were 712 records for analysis; 391 (54.9%) LS performed and 321 (45.1%) underwent amputation. The rate of LS was statistically higher among patients treated at Level I TCs vs those treated at Level II TCs (47.4% vs 34.8%; p = 0.01). Patients with penetrating injuries (13% vs 9.5%; p = 0.046) and tibial/peroneal artery injury (72.9% vs 50.4%; p < 0.001), as opposed to popliteal artery injury (30.8% vs 58.8%; p < 0.001), were more likely to have LS. The risk-adjusted odds of LS was 3.13 times higher at Level I TCs vs Level II TCs (95% CI, 1.59 to 6.34; p = 0.001). Limb salvage rates were significantly higher at Level I TCs compared with Level II TCs (53.0% vs 34.8%; p = 0.004), even after propensity matching.ConclusionsIn patients with a mangled extremity, limb salvage rates are 50% higher at Level I TCs compared with Level II TCs, independent of case mix and injury severity.

Project description:BackgroundAcute geriatric treatment is a type of early rehabilitation for hospitalized seniors to maintain personal autonomy and to avoid nursing home placement.ObjectiveThe aim of the study was to describe the changes of mobility and functional independence of older trauma patients during acute geriatric treatment.Material and methodsThis study analyzed admission and discharge assessment data from 164 patients in the geriatric department with fall-related injuries. Mobility and performance in activities of daily living were assessed using the short physical performance battery (SPPB), gait speed and Barthel index. We analyzed changes in mobility from admission to discharge (t-test) and examined differences in mobility between patients returning home and those admitted to long-term care (age-adjusted and gender-adjusted linear regression model).ResultsPatients improved their mobility measured by the SPPB by 1.8 points ± 2.1 points, gait speed by 0.10 ± 0.14 m/s and the Barthel index by 13 ± 16 points, all p < 0.001). The number of patients not able to walk decreased from 43% to 14% (p = 0.003). Of the community-dwelling patients 73% were discharged either directly back home or after rehabilitation outside the hospital as a transitional solution.ConclusionIn the context of acute geriatric treatment older trauma patients significantly improved their mobility and performance. The majority of patients could return home.

Project description:Importance:Numerous studies have demonstrated that long-term outcomes after orthopedic trauma are associated with psychosocial and behavioral health factors evident early in the patient's recovery. Little is known about how to identify clinically actionable subgroups within this population. Objectives:To examine whether risk and protective factors measured at 6 weeks after injury could classify individuals into risk clusters and evaluate whether these clusters explain variations in 12-month outcomes. Design, Setting, and Participants:A prospective observational study was conducted between July 16, 2013, and January 15, 2016, among 352 patients with severe orthopedic injuries at 6 US level I trauma centers. Statistical analysis was conducted from October 9, 2017, to July 13, 2018. Main Outcomes and Measures:At 6 weeks after discharge, patients completed standardized measures for 5 risk factors (pain intensity, depression, posttraumatic stress disorder, alcohol abuse, and tobacco use) and 4 protective factors (resilience, social support, self-efficacy for return to usual activity, and self-efficacy for managing the financial demands of recovery). Latent class analysis was used to classify participants into clusters, which were evaluated against measures of function, depression, posttraumatic stress disorder, and self-rated health collected at 12 months. Results:Among the 352 patients (121 women and 231 men; mean [SD] age, 37.6 [12.5] years), latent class analysis identified 6 distinct patient clusters as the optimal solution. For clinical use, these clusters can be collapsed into 4 groups, sorted from low risk and high protection (best) to high risk and low protection (worst). All outcomes worsened across the 4 clinical groupings. Bayesian analysis shows that the mean Short Musculoskeletal Function Assessment dysfunction scores at 12 months differed by 7.8 points (95% CI, 3.0-12.6) between the best and second groups, by 10.3 points (95% CI, 1.6-20.2) between the second and third groups, and by 18.4 points (95% CI, 7.7-28.0) between the third and worst groups. Conclusions and Relevance:This study demonstrates that during early recovery, patients with orthopedic trauma can be classified into risk and protective clusters that account for a substantial amount of the variance in 12-month functional and health outcomes. Early screening and classification may allow a personalized approach to postsurgical care that conserves resources and targets appropriate levels of care to more patients.

Project description:ObjectiveTo corroborate anecdotal evidence with systematic evidence of a lower threshold for admission among for-profit hospitals.Data sourcesThe study used Florida emergency department and hospital discharge datasets for 2012 to 2014. The treatment variable of interest was for-profit-designated trauma center status. The dependent variable indicated whether a patient with mild-to-moderate injuries was admitted after presenting as a trauma alert and then discharged to home. A separate analysis was conducted of discharges that had a 1-day length of stay.Study designGeneralized estimation equations with logistic distribution models were used to control for the confounding influences and developed for four groups of patients: ICISS = 1 (no probability of mortality), ICISS ? 0.99, ICISS ? 0.95, and ICISS ? 0.85 (zero to 15 percent probability of mortality, which includes all mild and moderate injury patients).Principal findingsFor the ICISS = 1 and ICISS ? 0.99 models, the centers' for-profit status was the most important predictor. In the ICISS ? 0.95 and ICISS ? 0.85 models, injury type played a more important role, but for-profit status remained important. For patients with a 1-day stay, for-profit status was associated with an even higher probability of hospitalization.ConclusionsConsiderable differences exist between for-profit and not-for-profit trauma centers concerning hospitalization among the study population, which may be explained by supplier-induced demand.

Project description:ImportanceTo date, measurement and treatment of older adult fall injury has been siloed within specific care settings, such as a hospital or within a nursing home or community. Little is known about changes in fall risk across care settings. Understanding the occurrence of falls across settings has implications for measuring and incentivizing high-value care across care settings.ObjectiveTo estimate the risk of older adult fall injury within and across discrete periods during a 12-month care episode anchored by an acute hospitalization.Design, setting, and participantsThis cohort study is a longitudinal analysis of 12-month periods that include an anchor hospital stay using national data from 2006 to 2014. Participants included older (aged ≥65 years) Medicare fee-for-service beneficiaries from the Health and Retirement Study. Weekly fall injury rates were computed for 4 periods compared with the anchor hospitalization: at baseline (1-6 months before hospitalization), just before (<1 month before hospitalization), just after (<1 month after hospitalization), and at follow-up (1-6 months after hospitalization). Piecewise logistic regression models estimated weekly marginal risk of fall injury within each period, adjusting for sociodemographic and health characteristics. Fall injury risks for high-risk beneficiaries with a fall injury during the anchor hospitalization were also estimated. Data analysis was performed from November 2019 to April 2020.Main outcomes and measuresFall injuries.ResultsIn total, 10 106 anchor hospitalizations for 4101 beneficiaries (mean [SD] age, 77.1 [7.6] years; 5912 hospitalizations among women [58.5%]) were identified. The overall fall injury risk was 0.77%. In adjusted models, marginal increases in weekly fall injury risk just before hospitalization (0.27 percentage points [95% CI, 0.22 to 0.33 percentage points], or 30.0%; P < .001) were 4 times greater than decreases just after hospitalization (-0.18 percentage points [95% CI, -0.23 to -0.13 percentage points], or -9.2%; P < .001)]. A greater risk differential before and after hospitalization was observed for patients with an inpatient fall injury (1.89 percentage points [95% CI, 1.37 to 2.40], or 309.8%; P < .001; vs -0.39 percentage points [95% CI, -0.73 to -0.04], or -11.6%; P = .03).Conclusions and relevanceAn episode-based assessment of fall injury illustrates substantial variability in period-specific risks over an extended period including an anchor hospitalization. Risk transitions between periods include sizable increases just before hospitalization that do not fully subside after hospital discharge. Financial incentives to coordinate hospital and posthospital care for patients at risk for fall injury are needed. These could include bundled payments for fall injury episodes that incentivize coordination across settings.

Project description:ImportanceAs the US population ages, public health agencies have released guidelines encouraging aerobic activity and muscle-strengthening exercises among older individuals. Facial trauma from such activities among elderly individuals has long been underappreciated.ObjectivesTo evaluate the incidence of recreational activity-associated facial fractures among older adults and to further delineate injury characteristics including demographics, fracture location, and specific activities.Design, setting, and participantsThe National Electronic Injury Surveillance System was used to collect data on emergency department visits from January 1, 2011, to December 31, 2015, for individuals 55 years of age or older who sustained facial fractures from recreational activities. Individual entries were evaluated for activity code, fracture site, and demographics. Weighting data were used to extrapolate national incidence.Main outcomes and measuresIncidence and location of facial fractures and associated recreational activity.ResultsDuring the study period, there were 20?519 emergency department visits for recreational activity-associated facial fractures among adults 55 years of age or older (8107 women and 12?412 men; mean [SD] age, 66.5 [9.1] years). The annual incidence of facial fractures increased by 45.3% from 2011 (n?=?3174) through 2015 (n?=?4612). Bicycling (26.6%), team sports (15.4%), outdoor activities (10.1%), and gardening (9.5%) were the most common causes of facial fractures. Walking and jogging caused 5.5% of fractures. In cases specifying site of fracture, nasal (65.4%) and orbital (14.1%) fractures were the most common. A greater proportion of men than women sustained bicycle-associated fractures (35.7% vs 14.9%; P?=?3.1056?×?10-170), while more women than men sustained fractures associated with gardening (15.5% vs 6.1%; P?=?2.1029?×?10-97), outdoor activities (14.6% vs 7.7%; P?=?4.3156?×?10-50), and gym exercise (7.7% vs 1.3%; P?=?3.0281?×?10-114). Men harbored a greater likelihood than women of orbital (14.9% vs 12.8%; P?=?6.1468?×?10-5) and mandible fractures (9.3% vs 2.0%; P?=?9.3760?×?10-64). Walking and jogging and gardening comprised a greater proportion of injuries in older cohorts.Conclusions and relevanceFacial fractures sustained from recreational activity increased by 45.3% during a 5-year period among older adults. Although bicycling was the most common activity facilitating these injuries, many other pursuits represent areas of concern. Nasal fractures predominated, although orbital fractures increased with age. These findings offer areas for targeted prevention and provide valuable information for patient counseling. Furthermore, initiatives encouraging greater activity among this population may need to be accompanied by guidelines for injury prevention.Level of evidenceNA.

Project description:PurposeCharacterize ocular trauma and visual outcomes from firework injuries at a level I trauma center.MethodsRetrospective review of all firework injuries at Harborview Medical Center between 2003 and 2013.ResultsThree hundred and twenty-seven patients sustained firework injuries, of which 100 (31%) sustained ocular injuries. The average age of all patients who sustained fireworks injuries was 24.2 years, 89% were male and 54% of injuries occurred within 48?h of 4 July. Ocular injuries were most commonly caused by mortars (24%) and rockets (22%). Rockets were associated with four times the frequency of ocular injuries as compared with non-ocular injuries (P<0.001). Spectators were more likely to sustain ocular injuries than non-ocular injuries (P=0.001). The most common injuries sustained were corneal abrasions (67%), hyphemas (42%), eyelid injuries (39%), and ruptured globes (17%). Twenty-eight percent of patients with ocular injuries required surgical intervention. Ruptured globes occurred in 17% of patients, with the majority being complex corneoscleral lacerations. Fifty-eight percent of patients who sustained ruptured globes were left with no light perception in the affected eye. Average follow-up was 188 days. Average visual acuity significantly improved from logMAR 1.8±1.6 at presentation to logMAR 1.3±1.8 at last follow-up.ConclusionsFirework-related ocular trauma frequently results in vision-threatening pathology. Prompt referral to and treatment by ophthalmologists is critical. This study documents the dangers inherent in the personal use of fireworks and provides data that may help guide public policy to decrease the frequency of these devastating injuries.
