RESUMEN
BACKGROUND: Identifying ideal candidates for orthopaedic surgery residency is difficult. Data available for applicant selection are evolving; preclinical grades and the Alpha Omega Alpha (AOA) honors society are being phased out at some medical schools. Similarly, three-digit United States Medical Licensing Examination (USMLE) Step 1 scores have been eliminated. There is renewed interest in improving resident selection to provide a diverse, comprehensive educational opportunity that produces orthopaedic surgeons who are prepared for practice. QUESTIONS/PURPOSES: We sought to identify whether (1) academic achievements, (2) letters of recommendation, (3) research activity, and (4) miscellaneous factors available on Electronic Residency Application Service (ERAS) applications were associated with outstanding residency performance. METHODS: Ten faculty members (22% of all full-time faculty) with extensive educational involvement for at least 7 years, whose expertise covered all subspecialty departments at an urban, academic orthopaedic surgery residency program, were given an anonymous survey on the performance of the four most recent classes of residency graduates (24 residents). This survey was developed due to the lack of a validated residency outcomes tool or objective metrics for residency performance. The evaluated criteria were decided upon after discussion by a relatively large group of academic orthopaedic surgeons considering the factors most important for graduating orthopaedic residents. The faculty were selected based on their long-term knowledge of the residency, along with their diversity of specialty and backgrounds; there were no nonresponders. Faculty graded each resident on a scale from 1 to 10 (higher is better) on six criteria: surgical technical skills, research productivity, clinical knowledge, professionalism, personality, and fellowship match. The mean of the faculty ratings made by all faculty for all six criteria was calculated, producing the overall residency performance score. Factors available on each resident's ERAS application were then correlated with their overall residency performance score. Categorical ERAS factors, including AOA status, five or more honors in core clerkships, at least three exceptional letters of recommendation, collegiate athletics participation, expertise with a musical instrument, and research (6-year) track residents, were correlated with overall residency performance score via point biserial analysis. Continuous ERAS factors including USMLE Step 1 and Step 2 scores, number of publications before residency, number of research years before residency, medical school ranking, and number of volunteer experiences were correlated with overall residency performance score via Pearson correlation. USMLE Step 1 three-digit scores were evaluated despite their recent elimination because of their historic importance as a screening tool for residency interviews and for comparison to USMLE Step 2, which retains a three-digit score. Application factors with a p < 0.2 on univariate analysis (five or more honors in core clerkships, at least three exceptional letters of recommendation, research track residents) were included in a stepwise linear regression model with "overall residency performance score" as the outcome variable. All p values < 0.05 were considered significant. RESULTS: The mean overall residency performance score was 7.9 ± 1.2. Applicants with at least five honors grades in core clerkships had overall residency performance scores 1.2 points greater than those of their peers (95% confidence interval (CI) 0.3 to 2.0; p = 0.01, Cohen ƒ 2 = 0.2, representing a small effect size). ERAS applications including at least three exceptional letters of recommendation were associated with a 0.9-point increase in residency performance (95% CI 0.02 to 1.7; p = 0.046, Cohen ƒ 2 = 0.1, representing a small effect size). Participation in the residency research (6-year) track was associated with a 1-point improvement in residency performance (95% CI 0.1 to 1.9; p = 0.03, Cohen ƒ 2 = 0.2, again, representing a small effect size). Together, these three factors accounted for 53% of the variance in overall residency performance score observed in this study. CONCLUSION: Past clinical excellence, measured by core clerkship grades and exceptional letters of recommendation, is associated with slightly improved overall orthopaedic residency performance scores. Applicants meeting both criteria who also complete a research track residency may perform substantially better in residency than their counterparts, as these three factors accounted for half of all the variance observed in the current study. Although minimum requirements are necessary, traditionally used screening factors (such as USMLE scores, AOA status, medical school rank, and number of publications) may be of less utility in identifying successful future residents than previously thought. LEVEL OF EVIDENCE: Level III, therapeutic study.

BACKGROUND: Patient function after arthrodesis of the first metatarsophalangeal joint (MTPJ) relies on proper positioning of the first MTPJ. To maximize the likelihood of good postoperative function, the dorsiflexion angle, referred to as the fusion sagittal angle, should range between 20° and 30°, corresponding to 10° to 15° of dorsiflexion off the weightbearing axis. However, achieving appropriate sagittal alignment intraoperatively is challenging. The artificial floor technique (AFT) uses a rigid, flat surface to simulate the weightbearing position of the foot intraoperatively to accurately position the first MTPJ without fluoroscopy. This technique has been previously described and is commonly used but, to our knowledge, it has never been validated. QUESTIONS/PURPOSES: (1) Is the AFT a valid and repeatable technique for positioning the fusion sagittal angle between 20° and 30° of dorsiflexion from the first metatarsal? (2) Does the fusion sagittal angle obtained using the AFT vary with foot size? METHODS: In this retrospective study, a search was performed using Current Procedural Terminology codes for patients undergoing first MTPJ arthrodesis by one surgeon between June 2012 and June 2020. The surgical technique used during this time did not vary and consisted of the use of a rigid, flat, sterile surface. The entire foot was placed flat on the surface, simulating the weightbearing position and allowing for an evaluation of the fusion sagittal angle of the first MTPJ. The target sagittal alignment was achieved when the soft tissue of the plantar surface at the distal-most aspect of the proximal phalanx was measured (using a sterile ruler) as 1 cm off the artificial floor. The recommended fusion sagittal angle falls within a range of 20° to 30°, which allows for 1-mm to 2-mm variations in measuring the elevation of the proximal phalanx off the artificial floor. Fixation was achieved with two 2.8-mm threaded, double-pointed Steinmann pins placed through the intramedullary canal of the proximal and distal phalanges and into the first metatarsal. Once fixation was achieved, the fusion sagittal angle was confirmed with the AFT without using fluoroscopy. Postoperatively, patients were allowed to bear weight fully on their heels in a postoperative, rigid-soled shoe. During the study period, 117 patients (135 feet) underwent first MTPJ arthrodesis utilizing the AFT for either first MTPJ arthritis/hallux rigidus, hallux valgus, or inflammatory arthropathy. Of those, we considered patients with preoperative AP and lateral weightbearing radiographs and patients with AP and lateral weightbearing radiographs at 3 months postoperatively after the removal of the internal fixation construct as eligible for analysis. Based on these criteria, 84% (113 of 135) of feet were included in the final radiographic analysis. Sixteen percent (22 of 135) of the feet were excluded because postoperative radiographs demonstrating the removal of the internal fixation construct were absent from the Picture Archiving and Communication System (PACS) in these cases. The length of the whole foot, first metatarsal, and proximal phalanx were measured on preoperative weightbearing radiographs. In addition, fusion sagittal angles were measured on weightbearing radiographs after removal of internal fixation construct at a minimum of 3 months postoperatively (mean 3.5 ± 2.2 months). No patients were lost to follow-up before obtaining those radiographs. Two qualified reviewers independently evaluated each radiograph. We ascertained inter- and intraobserver reliability using intraclass correlation coefficients (ICCs). We determined whether the fusion sagittal angle obtained using the AFT varied with foot size by using a multiple linear regression model. RESULTS: In the entire study group, the mean fusion sagittal angle using the AFT was 27° ± 4°. The interobserver ICC of the fusion sagittal angle measurements was 0.92 (95% confidence interval [CI] 0.56 to 0.97; p < 0.001). The intraobserver ICC for reviewer 1 was 0.95 (95% CI 0.92 to 0.97; p < 0.001) and the intraobserver ICC for reviewer 2 was 0.97 (95% CI 0.88 to 0.98; p < 0.001). Ninety-one percent (103 of 113) of the study group fell within the acceptable range of 20° to 30° ± 2°. The multiple linear regression analyses demonstrated that the preoperative lengths of the whole foot (ß =-0.05 [95% CI -0.12 to 0.02]; p = 0.16), proximal phalanx (ß =-0.13 [95% CI -0.46 to 0.20]; p = 0.44), and first metatarsal (ß = 0.13 [95% CI -0.10 to 0.35]; p = 0.27) were not independently associated with the postoperative fusion sagittal angle. CONCLUSION: The AFT allows for accurate and reproducible positioning of the first MTPJ within the appropriate functional range of dorsiflexion, regardless of foot size. Additionally, this technique can be performed without fluoroscopy and so avoids radiation exposure to the patient and the surgical team. LEVEL OF EVIDENCE: Level III, therapeutic study.

BACKGROUND: In an era of increasing healthcare costs, the number and value of nonclinical workers, especially hospital management, has come under increased study. Compensation of hospital executives, especially at major nonprofit medical centers, and the "wage gap" with physicians and clinical staff has been highlighted in the national news. To our knowledge, a systematic analysis of this wage gap and its importance has not been investigated. QUESTIONS/PURPOSES: (1) How do wage trends compare between physicians and executives at major nonprofit medical centers? (2) What are the national trends in the wages and the number of nonclinical workers in the healthcare industry? (3) What do nonclinical workers contribute to the growth in national cost of healthcare wages? (4) How much do wages contribute to the growth of national healthcare costs? (5) What are the trends in healthcare utilization? METHODS: We identified chief executive officer (CEO) compensation and chief financial officer (CFO) compensation at 22 major US nonprofit medical centers, which were selected from the US News & World Report 2016-2017 Hospital Honor Roll list and four health systems with notable orthopaedic departments, using publicly available Internal Revenue Service 990 forms for the years 2005, 2010, and 2015. Trends in executive compensation over time were assessed using Pearson product-moment correlation tests. As institution-specific compensation data is not available, national mean compensation of orthopaedic surgeons, pediatricians, and registered nurses was used as a surrogate. We chose orthopaedic surgeons and pediatricians for analysis because they represent the two ends of the physician-compensation spectrum. US healthcare industry worker numbers and wages from 2005 to 2015 were obtained from the Bureau of Labor Statistics and used to calculate the national cost of healthcare wages. Healthcare utilization trends were assessed using data from the Agency for Healthcare Quality and Research, the National Ambulatory Medical Care Survey, and the National Hospital Ambulatory Medical Care Survey. All data were adjusted for inflation based on 2015 Consumer Price Index. RESULTS: From 2005 to 2015, the mean major nonprofit medical center CEO compensation increased from USD 1.6 ± 0.9 million to USD 3.1 ± 1.7 million, or a 93% increase (R = 0.112; p = 0.009). The wage gap increased from 3:1 to 5:1 with orthopaedic surgeons, from 7:1 to 12:1 with pediatricians, and from 23:1 to 44:1 with registered nurses. We saw a similar wage-gap trend in CFO compensation. From 2005 to 2015, mean healthcare worker wages increased 8%. Management worker wages increased 14%, nonclinical worker wages increased 7%, and physician salaries increased 10%. The number of healthcare workers rose 20%, from 13 million to 15 million. Management workers accounted for 3% of this growth, nonclinical workers accounted for 27%, and physicians accounted for 5% of the growth. From 2005 to 2015, the national cost-burden of healthcare worker wages grew from USD 663 billion to USD 865 billion (a 30% increase). Nonclinical workers accounted for 27% of this growth, management workers accounted for 7%, and physicians accounted for 18%. In 2015, there were 10 nonclinical workers for every one physician. The cost of healthcare worker wages accounted for 27% of the growth in national healthcare expenditures. From 2005 to 2015, the number of inpatient stays decreased from 38 million to 36 million (a 5% decrease), the number of physician office visits increased from 964 million to 991 million (a 3% increase), and the number of emergency department visits increased from 115 million to 137 million (a 19% increase). CONCLUSIONS: There is a fast-rising wage gap between the top executives of major nonprofit centers and physicians that reflects the substantial, and growing, cost of nonclinical worker wages to the US healthcare system. However, there does not appear to be a proportionate increase in healthcare utilization. These findings suggest a growing, substantial burden of nonclinical tasks in healthcare. Methods to reduce nonclinical work in healthcare may result in important cost-savings. LEVEL OF EVIDENCE LEVEL: IV, economic and decision analysis.

We have developed and tested two linked but separable structured inquiry exercises using a set of Drosophila melanogaster GAL4 enhancer trap strains for an upper-level undergraduate laboratory methods course at Bucknell University. In the first, students learn to perform inverse PCR to identify the genomic location of the GAL4 insertion, using FlyBase to identify flanking sequences and the primary literature to synthesize current knowledge regarding the nearest gene. In the second, we cross each GAL4 strain to a UAS-CD8-GFP reporter strain, and students perform whole mount CNS dissection, immunohistochemistry, confocal imaging, and analysis of developmental expression patterns. We have found these exercises to be very effective in teaching the uses and limitations of PCR and antibody-based techniques as well as critical reading of the primary literature and scientific writing. Students appreciate the opportunity to apply what they learn by generating novel data of use to the wider research community.

Purpose When treating limb length discrepancy (LLD), decisions regarding lengthening versus contralateral shortening require careful consideration of deformity and patient factors. Using the National Longitudinal Survey of Youth 1979 (NLSY79) database, and income as a quantitative representation of overall socioeconomic benefit, we sought to determine the height at which incremental gains in height have the greatest value. Methods Using the NLSY79 database, we collected demographic data, height, yearly income from wages, college education (full- or part-time), and receipt of government financial aid. Multiple-linear regression and graphical analysis were performed. Results The study population included 9,652 individuals, 4,775 (49.5%) males and 4,877 (50.5%) females. Mean heights were 70.0±3.0 inches and 64.3±2.6 inches for males and females, respectively. Multiple-linear regression analysis (adjusted-r²=0.33) demonstrated height had a standardized-ß=0.097 (p<0.001), even when accounting for confounding factors. Using graphical analysis, we estimated cut-offs of 74 inches for males and 69 inches for females, beyond which income decreased with incremental height. Conclusions Using income as a quantitative representation of socioeconomic value, our analysis found income increased with incremental height in individuals with predicted heights up to 74 inches for males and 69 inches for females. Shortening procedures might receive more consideration at predicted heights greater than these cut-offs, while lengthening might be more strongly considered at the lower ranges of height. Additionally, our multiple-linear regression analysis confirms the correlation between height and income, when factoring in other predictors of income.
RESUMEN
INTRODUCTION: Inability to drive a motor vehicle due to lower extremity injury is a major inconvenience. Timing of safe return to driving has not been much studied. Objective measurements such as time to brake (TTB) have been proposed; however, utility and concordance of functional outcome measurements have not been previously evaluated. The purpose of this project is to measure these parameters and to assess for associations with ability to safely return to driving, improving the ability of clinicians to assess for measurements of driving readiness without specifically measuring TTB. METHODS: A prospective, cohort study of 232 patients with complex lower extremity injuries to the pelvis, acetabulum, hip, femur, knee, tibia, ankle, and foot was performed. Time to brake (TTB) was measured once weightbearing was allowed. Function was assessed by the Musculoskeletal Function Assessment (MFA) questionnaire, and pain, mobility, and physical functions, via patient reported outcome measurement information system (PROMIS) surveys. RESULTS: Patients with longer TTB had significantly elevated MFA scores indicating increased musculoskeletal dysfunction post-injury. As the MFA score increased by 1 point, TTB increased by 0.013 s (p<0.001). PROMIS metrics were also significantly associated with patients experiencing more pain and worse mobility as TTB increased. DISCUSSION: Many patients continue to exhibit musculoskeletal dysfunction several months post-treatment for complex lower extremity injuries. Patients with better PROMIS metrics and MFA scores, and shorter TTB are more appropriate to return to driving. Surgeons may be better informed about safe driving ability by considering these measurements. LEVEL OF EVIDENCE: II.

Background Optimal lateral ankle imaging is important for the diagnosis and treatment of multiple ankle conditions. The effects of limb deformity on lateral ankle imaging are not well described and are clarified in this osteological study. Materials and methods We utilized an osteological collection and imaged all specimens after the first positioning of the talus in the lateral position and positioning the tibia and fibula to match. We then measured the relative positions of the tibia and fibula and their widths to calculate standard ratios. All measurements were evaluated for reliability using intra-class correlation coefficients. Multiple regression analysis determined how patient characteristics, tibial torsion, and medial proximal tibial angle affected various lateral ankle imaging ratios. Results The intra-class correlation coefficient was excellent for all measurements. In the multiple regression analysis, all five imaging ratios had at least one statistically significant outcome. The anterior tibiofibular interval (ATFI)-tibial width (TW) ratio (ATFI:TW) had only one association with sex and had the lowest standard deviation. All other parameters had variation with tibial torsion and/or medial proximal tibia angle (MPTA). The mean ATFI was 1.06 ± 0.21 cm and 1.19 ± 0.23 cm for females and males, respectively. Conclusions Patient sex and tibial torsion impacted the fidelity of lateral imaging parameters. ATFI:TW may pose the greatest utility given its minimal association with deformity parameters and low standard deviation.
RESUMEN
Astronomical increases in medical expenses and waste produce widespread financial and environmental impacts. Minor changes to minimize costs within orthopaedics, the most used surgical subspecialty, could result in substantial savings. However, few orthopaedic surgeons are educated or experienced to implement cost containment strategies. This study aims to investigate cost containment opportunities and provide a framework for educating and incorporating residents into cost-saving initiatives. Methods: Orthopaedic surgical residents from an academic program with a Level I trauma center were queried during 2019 to 2022 regarding suggestions for cost containment opportunities. Based on feasibility and the estimated impact, 7 responses were selected to undergo cost-saving analyses. Results: The proposed initiatives fell into 2 categories: minimizing waste and optimizing patient care. Eliminating nonessential physical therapy/occupational therapy consults led to the greatest estimated savings ($8.6M charges/year), followed by conserving reusable drill bits ($2.2M/year) and reducing computed tomography scans on lower extremity injuries ($446K/year). Conclusion: Current medical training provides limited formal education on cost-effective care. Efforts to mitigate the growing financial and environmental costs of health care should include encouraging and incorporating resident feedback into cost reduction strategies. This tactic will likely have a positive impact on the behavior of such resident surgeons as they enter practice and have more awareness of costs and value. Level of Evidence: V (cost-minimization study).
RESUMEN
INTRODUCTION: No guidelines exist for recommending return to driving. This study will examine time to brake (TTB) after lower extremity injuries versus in uninjured people. The potential effect of various types of lower extremity injuries on TTB will be measured. METHODS: Patients with injuries to the pelvis, hip, femur, knee, tibia, ankle, and foot underwent testing using a driving simulator to assess TTB. Comparison was with a control group of uninjured people. RESULTS: Two-hundred thirty-two patients with lower extremity injuries participated. The majority were in the tibia and ankle regions (47%). Mean TTB for control subjects was 0.74 seconds, compared with 0.83 for injured patients, noting a 0.09-second difference (P = 0.017). Left-sided injuries averaged TTB of 0.80 seconds, right-sided injuries averaged TTB of 0.86 seconds, and bilateral injuries averaged TTB of 0.83 seconds, all prolonged versus control subjects. The longest TTB was exhibited after ankle and foot injuries (0.89 seconds) while the shortest was after tibial shaft fractures (0.76 seconds). DISCUSSION: Any lower extremity injury caused a prolonged TTB compared with control patients. Left, right, and bilateral injuries all had longer TTB. Ankle and foot injuries experienced the longest TTB. Additional investigation is warranted to develop safe guidelines for return to driving.

PURPOSE: Cervical spinal cord injury can be a particularly devastating sequela of trauma. The purpose of this study was to describe the imaging findings of adult patients with cervical spinal cord injury without computed tomography evidence of trauma (SCIWOCTET). METHODS: All adult patients (≥18 years) treated for acute cervical SCIWOCTET at a single Level I adult trauma center over an eight-year period were retrospectively identified. CT imaging was evaluated for degenerative changes narrowing the midsagittal canal diameter (SCD) of the cervical spine and relative congenital cervical stenosis (CCS; congenital narrowing of the SCD <13 mm). Magnetic resonance imaging (MRI) scans were evaluated for signal intensity change (SIC) suspicious for cord edema/contusion as well as ligamentous injury, hemorrhage, and epidural hematoma. RESULTS: Ninety-six patients with cervical SCIWOCTET met inclusion criteria. The most common mechanism of injury was fall from standing (47.9%). On CT, 86 patients (89.6%) had CCS. Degenerative changes were present in 95 patients (99.0%). In 98/99 patients (99.0%), the point of narrowest cervical SCD was ≤8 mm. On MRI, 79 patients (82.3%) demonstrated signal intensity change (SIC) indicative of cord edema/contusion, while 16 (16.7%) had ligamentous injury. Intramedullary cord hemorrhage was seen in two patients (2.1%) and epidural hematoma in three (3.1%). CONCLUSION: Degenerative changes or CCS may narrow the minimum cervical SCD beyond the threshold at which low-energy trauma results in C-SCI. Adult patients with cervical spinal stenosis, whether congenital and/or degenerative, and neurologic findings referable to the cervical spine should be assessed for C-SCI.

Despite the rising prevalence of arthroplasty and aging population, limited data exist regarding differences in periprosthetic fracture clinical outcomes compared with native counterparts. This study compares differences in hospital treatment, morbidity, and mortality associated with periprosthetic distal femur fractures at an urban level 1 trauma center. We retrospectively reviewed all adult AO/OTA type 33 fractures (526) that presented to our institution between 2009 and 2018. In total, 54 native and 54 periprosthetic fractures were matched by age and gender. We recorded demographics, operative measures, length of stay (LOS), discharge disposition, and mortality. We used McNemar's and paired t-tests for analysis where appropriate (p < 0.05) (IBM SPSS Statistics for Windows, Version 26.0. Armonk, NY; IBM Corp.). The average age at injury was 74 years ± 12 (native) compared with 73 years ± 12 (periprosthetic). After 1:1 matching, the groups had similar body mass index (31.01 vs. 32.98, p = 0.966 for native and periprosthetic, respectively) and mechanisms of injury with 38 native and 44 periprosthetic (p = 0.198) fractures from low-energy falls. Both groups had 51/54 fractures managed with open reduction internal fixation with a locking plate. The remaining were managed via amputation or intramedullary nail fixation. Mean operative time (144 minutes (±64) vs. 132 minutes (±62), p = 0.96) and estimated blood loss (319 mL (±362) vs. 289 mL (±231), p = 0.44) were comparable between the native and periprosthetic groups, respectively. LOS: 9 days ± 7 (native) versus 7 days ± 5 (periprosthetic, p = 0.31); discharge disposition (to skilled nursing facility/rehab): n = 47 (native) versus n = 43 (periprosthetic, p = 0.61); and mortality: n = 6 (native) versus n = 8 (periprosthetic, p = 0.55). No significant differences were observed. We found no statistical differences in morbidity and mortality in periprosthetic distal femur fractures treated over 10 years at a level 1 trauma center. Native and periprosthetic AO/OTA type 33 distal femur fractures are serious injuries with similar outcomes at a level 1 trauma center.

INTRODUCTION: Firearm-related injuries impact the healthcare system, taxpayers, and injured patients due to lost productivity and reduced quality of life. The goal was to quantify the economic costs related to hospitalization for gunshot wounds (GSWs) at a single urban level 1 trauma center. MATERIALS AND METHODS: 941 patients over 27 months were treated for GSW. Elements related to hospitalization including length of stay, surgical procedures, medications and therapies, and subsequent readmission were identified, and costs were determined, inclusive of fixed and variable direct and indirect costs of facility care. Costs were classified based on body region: abdominal, chest, soft tissue, extremity or pelvic girdle, and head/neck/face. RESULTS: Mean age was 30 years, with 94% male. Most patients (81%) were admitted, and 8% sustained fatal injuries. Overall, 12% were seen previously or subsequently for additional, unrelated GSWs. Mean costs per patient were: $66,780 for abdominal GSWs; $3,986 for chest; $3,509 for soft tissue; $19,875 for extremities; $64,533 for head or neck, and means of $25,249 for two regions and $26,638 for three regions. Over the prospective period, 941 individuals sustained GSWs (approximately 35 per month). 37% were to the extremities, 23% were within the skin/subcutaneous tissue, 7% to the abdomen, 7% to the chest, 6% to the head or neck, and 20% to two or more body regions. Total facility costs for these 941 GSWs was $18.9 million, or $698,960 per month. 55% of the patients had Medicaid, and 33% were uninsured, resulting in substantial uncompensated expenses for the trauma center. CONCLUSION: Firearm-related injuries generate considerable expense. Our data underestimated cost, as professional services and indirect costs associated with lost economic productivity of patients and caregivers were excluded. No objective assessment of the disastrous personal and social impact was projected. Moving forward, interventions to prevent initial injury and recidivism in this high-risk population are crucial. LEVEL OF EVIDENCE: Level III.

INTRODUCTION: Patient-specific factors may influence posttraumatic stress disorder (PTSD) development and warrant further examination. This study investigates potential association between patient-reported fear of death at the time of injury and development of PTSD. METHODS: Over 35 months, 250 patients were screened for PTSD at their first posthospitalization clinic visit and were asked "Did you think you were going to die from this injury?" (yes or no). PTSD screening was conducted using the PTSD checklist for DSM-5 questionnaire. A score ≥33 was considered positive for PTSD, and patients were offered ancillary psychiatric services. Retrospectively, medical records were reviewed for baseline demographics and injury information. RESULTS: Forty-three patients (17%) indicated a fear of death. The mean age was 46 years, with patients who feared death being younger (36 versus 48, P < 0.001), and 62% were male. The most common mechanisms of injury were motor vehicle or motorcycle collisions (30%) and ground-level falls (21%). Gunshot wounds were more common among patients who feared death from trauma (44% versus 7%, P < 0.001). PTSD questionnaires were completed a median of 26 days after injury, with an average score of 12.6. PTSD scores were higher for patients with fear of death (32.7 versus 8.5), and these patients required more acute interventions (47% versus 7%), both P < 0.001. After multivariable logistic regression, patients who thought that they would die from their trauma had >13 times higher odds of developing PTSD (odds ratios: 13.42, P < 0.0001). Apart from positive psychiatric history (OR: 5.46, P = 0.001), no factors (ie, age, sex, mechanism, or any injury or treatment characteristic) were predictive of positive PTSD scores on regression. DICUSSION: Patients who reported fear of death at the time of injury were 13 times more likely to develop PTSD. Simply asking patients whether they thought that they would die at the time of injury may prospectively identify PTSD risk. LEVEL OF EVIDENCE: Prognostic Level II.

OBJECTIVES: To identify comorbidities and injury characteristics associated with surgical site infection (SSI) following internal fixation of malleolar fractures in an urban level 1 trauma setting. DESIGN: Retrospective. SETTING: Level 1 trauma center. PATIENTS/PARTICIPANTS: Seven-hundred seventy-six consecutive patients with operatively managed malleolar fractures from 2006 to 2016. INTERVENTION: Open reduction internal fixation. MAIN OUTCOME MEASUREMENTS: Superficial SSI (erythema and drainage treated with oral antibiotics and wound care) or deep SSI (treated with surgical debridement and antibiotics). RESULTS: Fifty-six (7.2%) patients developed SSI, with 17 (30%) of these being deep infections. An a-priori power analysis of nâ=â325 (α=0.05, ß=0.2) was tabulated for differences in univariate analysis. Univariate analysis identified categorical associations (Pâ<â.05) between SSI and diabetes mellitus, drug abuse, open fracture, and renal disease but not tobacco abuse, body mass index, or neuropathy. Multivariate logistic regression identified categorical associations between diabetes (ORâ=â2.2, 95% CI: 1.1-4.3), drug abuse (ORâ=â3.9, 95% CI: 1.2-12.7), open fracture (ORâ=â4.1, 95% CI: 1.3-12.8), and renal disease (ORâ=â2.7, 95% CI: 1.4-5.0) and any (superficial or deep) SSI. A separate multivariate logistic regression analysis found categorical associations between deep SSI requiring reoperation and diabetes (ORâ=â4.4, 95% CI: 1.6-12.2) and open fracture (ORâ=â4.1, 95% CI: 1.3-12.8). Furthermore, American society of anesthesiologists classification (ASA) Class 4 patients were (ORâ=â9.2, 95% CI: 2.0-41.79) more likely to experience an SSI than ASA Class 1 patients. CONCLUSIONS: Factors associated with SSI following malleolar fracture surgery in a single urban level 1 trauma center included diabetes, drug abuse, renal disease, and open fracture. The presence of diabetes or open type fractures were associated with deep SSI requiring reoperation. LEVEL OF EVIDENCE: Level 3 prognostic: retrospective cohort study.
RESUMEN
BACKGROUND: In the background of increasing competition between trauma centers, this study investigated the relative reimbursement of trauma care provided in an urban trauma setting, comparing patients previously unknown (new) to the system, representing potential sources of new revenue, and those who were known (established), having received medical care previously in the same system. METHODS: A retrospective review of 440 patients with high-energy fractures at a single level 1 trauma center was conducted. Payment to charge (P/C) ratios for professional and facilities services within 6 months of injury were calculated. RESULTS: Mean professional charges per patient were $35,522 and $30,639 (P = 0.11), between new and established patients, respectively, whereas mean professional payments were statistically different, $7,894 and $4,365 (P < 0.001). Mean differences in P/C for facilities payments for new and established patients were not statistically significant, but professional P/C was higher in new patients (P < 0.001), consistent with better insured patients. DISCUSSION: Insurance companies reimburse for professional or facilities services with statistically different P/C ratios. Treating new patients at our institution likely benefits our institution by offering exposure to a more favorable payer mix and more complex patients. LEVEL OF EVIDENCE: Retrospective level III.

OBJECTIVES: To evaluate a noninvasive hemoglobin measurement device in an orthopaedic trauma population. DESIGN: Prospective. SETTING: Level 1 trauma center. PATIENTS/PARTICIPANTS: One hundred five patients consecutively admitted to the orthopaedic trauma service after surgical treatment of fracture. INTERVENTION: Transcutaneous hemoglobin (TcHgb) monitoring using the Masimo Pronto Pulse CO-Oximeter model with Rainbow SET Technology for spot TcHgb measurement. MAIN OUTCOME MEASUREMENTS: TcHgb measurements and standard venipuncture hemoglobin (vHgb) were obtained. Patient preferences for each were recorded. RESULTS: TcHgb measurements were obtained in 100 patients and compared with their corresponding vHgb measurements. The mean vHgb and TcHgb were 10.2 ± 1.9 g/dL and 11.2 ± 2.1 g/dL, respectively, and the mean difference was 1.1 ± 1.6 g/dL, which was statistically different from 0 (P < 0.001). In 76% of cases, the TcHgb device overestimated vHgb. In a subgroup of patients undergoing procedures with minimal expected blood loss (external fixators of knee or ankle, irrigation and debridement, or open reduction and internal fixation of ankle or calcaneal fractures), the mean difference between vHgb and TcHgb was 0.68 ± 1.6 g/dL (P = 0.06). CONCLUSIONS: A preliminary study of TcHgb monitoring with the tested device as a potential screening mechanism to limit unnecessary blood draws showed statistical difference from vHgb; however, the mean bias 1.1 g/dL of hemoglobin was notably small. In a subgroup of patients undergoing procedures with minimal expected blood loss, the device may have merit. Larger studies are required to determine the clinical relevance of differences in measurements between the 2 methods. LEVEL OF EVIDENCE: Diagnostic Level II.

INTRODUCTION: The purpose of this study is to assess the impact of Trauma Recovery Services (TRS), a program facilitating engagement and recovery on satisfaction after orthopaedic trauma. METHODS: Two hundred ninety-four patients with surgically managed extremity fractures were prospectively surveyed. Satisfaction was assessed after 12 months using a 13-question telephone survey, rated on a Likert scale from 1 to 5 (with five being excellent). TRS resource utilization during and after hospitalization was recorded. Eighty-eight patients (30%) used TRS. RESULTS: Overall satisfaction was high with a mean score of 4.32. Although no differences were observed between the control group and patients with TRS utilization in age, sex, race, insurance, smoking history, or employment status, TRS patients sustained more high-energy mechanisms (81% versus 56%) and had more associated psychiatric illness (33% versus 17%), both P < 0.01. Multivariable regression indicated general exposure to TRS to be an independent predictor of higher overall care ratings (B = 1.31; P = 0.03). DISCUSSION: Utilization of TRS was the greatest predictor of better overall care ratings. This study builds on existing evidence demonstrating the positive impact of Trauma Survivor Network programming. We conclude that a hospital-wide program supporting patient education and engagement can effectively increase patient satisfaction after traumatic injury. LEVEL OF EVIDENCE: Prognostic Level II.

OBJECTIVES: What are the differences between elective and trauma patient satisfaction and do patient and diagnosis factors predict physician scores? DESIGN: Prospective cohort study. SETTING: Urban Level 1 Trauma center. PATIENTS/PARTICIPANTS: Three hundred twenty-three trauma patients and 433 elective orthopaedic patients treated at our center by the same surgeons. INTERVENTION: Trauma patients treated surgery for one or more fractures; elective patients treated with hip, knee, or shoulder arthroplasty, or rotator cuff repair. MAIN OUTCOME MEASUREMENTS: Telephone survey regarding patient experience and satisfaction with their care. The survey included questions from Hospital Consumer Assessment of Healthcare Providers and Systems (HCAHPS) surveys, and responses were rated on a 1-5 point Likert scale (5 best). RESULTS: Elective surgery patients had mean age of 56.4 years, and trauma patients were mean 50.3 years of age. Trauma patients rated their likelihood to make a full recovery lower than elective patients (median, interquartile range), 5.0 (1.0) versus 4.0 (2.0) (P < 0.001). After multivariate binary logistic regression, patients who rated the hospital higher (≥4 vs. ≤3) were more likely (odds ratio = 10.0, 95% confidence interval, 6.4-15.8) to score physicians better. Similarly, patients who scored their overall likelihood of recovering ≥4 compared with ≤3 were more likely (odds ratio = 3.6, 95% confidence interval, 2.9-5.6) to rate their physicians more positively. CONCLUSIONS: Patient perceptions including their likelihood to make a full recovery and their overall impression of the hospital predicted higher physician scores. We conclude that these physician scores are subject to patient perception biases and are not independent of the overall care experience. We recommend HCAHPS and physician ratings' web sites include internal controls, such as the patient perception of overall likelihood to recover, to aid in interpreting survey results.

OBJECTIVE: To calculate the revenue generated for injury- and noninjury-related services after the initial injury event in an orthopaedic trauma population. DESIGN: Retrospective cohort study. SETTING: Single Level 1 trauma center. PARTICIPANTS: Four hundred forty adult trauma patients treated operatively for spine, pelvis, and/or upper or lower extremity fractures with ≥1 night stay. INTERVENTION: Operative fracture management. MAIN OUTCOME MEASUREMENT: Revenue for follow-up care and for noninjury-related indications for 24 months. RESULTS: Most patients returned for follow-up (92.3%), generating 6704 visits with professional and technical collections of $8,135,022 and $37,292,722, respectively, per 1000 unique patients. The greatest revenue was from rehabilitation services. Patients were less likely to return if they resided outside adjacent counties [odds ratio (OR) = 0.16], experienced a complication (OR = 0.38), or were older (OR per 10-year increase: 0.66) (all P < 0.0001). More than 70% of trauma patients were new to our system, accounting for 33% of all subsequent noninjury-related visits, most for primary care (25.6%). Male patients [OR = 3.28, 95% confidence interval (CI), 1.08-9.93], nonwhites (OR = 3.41; 95% CI, 1.41-8.28), and patients residing near the trauma center (OR = 16.1, 95% CI, 2.13-121) were more likely to return (P < 0.0001). Realized noninjury-related professional and technical revenue was $506 per operative orthopaedic trauma case. CONCLUSIONS: Demographics and outcomes predict likelihood of follow-up. Rehabilitation services account for the greatest revenue per patient. The greatest number of return visits was for primary care services; awareness of such services, especially in men and in those residing near the hospital system, could improve retention.
