OBJECTIVES:(1) To demonstrate how a risk assessment tool modified to account for the COVID-19 virus during the current global pandemic is able to provide risk assessment for low-energy geriatric hip fracture patients. (2) To provide a treatment algorithm for care of COVID-19 positive/suspected hip fractures patients that accounts for their increased risk of morbidity and mortality. SETTING:One academic medical center including 4 Level 1 trauma centers, 1 university-based tertiary care referral hospital, and 1 orthopaedic specialty hospital. PATIENTS/PARTICIPANTS:One thousand two hundred seventy-eight patients treated for hip fractures between October 2014 and April 2020, including 136 patients treated during the COVID-19 pandemic between February 1, 2020 and April 15, 2020. INTERVENTION:The Score for Trauma Triage in the Geriatric and Middle-Aged ORIGINAL (STTGMAORIGINAL) score was modified by adding COVID-19 virus as a risk factor for mortality to create the STTGMACOVID score. Patients were stratified into quartiles to demonstrate differences in risk distribution between the scores. MAIN OUTCOME MEASUREMENTS:Inpatient and 30-day mortality, major, and minor complications. RESULTS:Both STTGMA score and COVID-19 positive/suspected status are independent predictors of inpatient mortality, confirming their use in risk assessment models for geriatric hip fracture patients. Compared with STTGMAORIGINAL, where COVID-19 patients are haphazardly distributed among the risk groups and COVID-19 inpatient and 30 days mortalities comprise 50% deaths in the minimal-risk and low-risk cohorts, the STTGMACOVID tool is able to triage 100% of COVID-19 patients and 100% of COVID-19 inpatient and 30 days mortalities into the highest risk quartile, where it was demonstrated that these patients have a 55% rate of pneumonia, a 35% rate of acute respiratory distress syndrome, a 22% rate of inpatient mortality, and a 35% rate of 30 days mortality. COVID-19 patients who are symptomatic on presentation to the emergency department and undergo surgical fixation have a 30% inpatient mortality rate compared with 12.5% for patients who are initially asymptomatic but later develop symptoms. CONCLUSION:The STTGMA tool can be modified for specific disease processes, in this case to account for the COVID-19 virus and provide a robust risk stratification tool that accounts for a heretofore unknown risk factor. COVID-19 positive/suspected status portends a poor outcome in this susceptible trauma population and should be included in risk assessment models. These patients should be considered a high risk for perioperative morbidity and mortality. Patients with COVID-19 symptoms on presentation should have surgery deferred until symptoms improve or resolve and should be reassessed for surgical treatment versus definitive nonoperative treatment with palliative care and/or hospice care.

INTRODUCTION/BACKGROUND:The purpose of this study was to combine a validated middle-age and geriatric trauma risk assessment tool (STTGMA) with a novel cost-prediction tool to create an objective triage tool for elderly hip fractures that would guide value-based care initiatives. METHODS:From October 2014 to January 2018, all patients aged ≥55 years who were admitted with a primary diagnosis of hip fracture to a single level 1 trauma center were enrolled. Upon evaluation in the emergency department, demographics, injury severity, and functional status were recorded to calculate the trauma triage score (STTGMARisk). A model to predict high-cost hip fracture patients was created using similar variables (STTGMACost). RESULTS:Three hundred sixty-one consecutive operative hip fracture patients were enrolled. Inpatient mortalities were skewed toward STTGMARisk3 with 21.4% of patients in this high-risk group ultimately expiring during their hospitalization. High-cost patients were correctly skewed to the STTGMACost2 and STTGMACost3 groups with 88.9% of all high-cost operatively treated hip fracture correctly triaged to these cohorts. Statistically significant variations were found in cost within each STTGMARisk group. CONCLUSIONS:A simple risk score calculated upon admission (STTGMARisk and STTGMACost) was able to be used as a triage tool not only to differentiate increased mortality risk but also to predict high-cost patients based on resource utilization in hip fracture patients. LEVEL OF EVIDENCE/METHODS:Prognostic, level II.

INTRODUCTION/BACKGROUND:Total hip arthroplasty (THA) is often used for displaced femoral neck fracture. In this study, institutional hip arthroplasty data were compared with the National American College of Surgeons National Surgical Quality Improvement Program (NSQIP) data for any differences in outcomes between our hospital, with an integrated hip fracture care pathway, and those of the country as a whole. METHODS:Elective THA was compared with arthroplasty performed for acute fracture. Outcomes for both groups included thromboembolic event (VTE), death, and deep prosthetic infection. RESULTS:Institutional data revealed no increased rate of infection after THA for fracture compared with elective. National Surgical Quality Improvement Program analysis revealed higher infection rates in fracture arthroplasty. There was an increased VTE rate in fracture performed for arthroplasty compared with elective in both institutional and NSQIP data. CONCLUSIONS:When performed at an academic medical center with an integrated care program, THA for fracture can have similar infection rates to elective THA. By contrast, national data showed significantly higher rates of infection and VTE for arthroplasty for fracture compared with elective. The contrast in complication rates may be related to well-functioning comprehensive interdisciplinary pathways. Patient-centered care pathways may be optimal for hip fracture patients.

Purpose/UNASSIGNED:The purpose of this study was 2-fold: 1) to investigate the age-related frequency, demographics and distribution of the middle-aged and geriatric orthopedic trauma population and 2) to describe the age-related frequency and distribution of hospital quality measure outcomes and inpatient cost. Methods/UNASSIGNED:All patients > 55 years of age who required orthopedic, trauma, or neurosurgery consults at 3 hospitals within an academic medical center from 2014 to 2017 were prospectively followed. On initial evaluation, each patient's demographics, injury severity, and functional status were collected. Patients were grouped into low and high-energy mechanism cohorts and divided into 5 groups based on age. Hospital quality measures including length of stay, complications, discharge location, and cost of care was compared between age groups. Data were analyzed using ANOVA and Chi-square tests. Results/UNASSIGNED:A total of 3965 patients were included in this study of which 3268 (82%) sustained low-energy trauma and 697 (18%) sustained high-energy trauma. With increasing age, more patients had more comorbidities, were less likely to be community ambulators, and more likely to use assistive devices (p < 0.05). Patients in older age groups had longer lengths of stay, more complications, were more likely to need ICU level care, and were less likely to be discharged home (p < 0.05). Rates of mortality were also greater in patients of more advanced age in both low and high-energy cohorts, and the calculated risk triage tool (STTGMA) score increased with each age bracket (p < 0.05). Total cost of care differed between age groups in the low-energy cohort (p = 0.003). Conclusion/UNASSIGNED:This epidemiological study provides a clear picture of the frequency and distribution of demographic, physiologic characteristics, outcomes, and cost of care in a middle-aged and geriatric orthopedic trauma population as evaluated by the STTGMA risk tool. Risk profiling of geriatric trauma patients allows for the establishment of baseline norms.

OBJECTIVES/OBJECTIVE:Investigate the efficacy of a novel geriatric trauma risk assessment tool (STTGMA) designed to predict inpatient mortality to risk stratify measures of hospital quality and cost of care in middle-aged and geriatric orthopaedic trauma patients. DESIGN/METHODS:Prospective cohort study SETTING:: Academic medical center PATIENTS:: 1592 patients aged 55 and older who were evaluated by orthopaedic surgery in the emergency department between 10/1/2014-9/30/2016. INTERVENTION/METHODS:Calculation of inpatient mortality risk score (STTGMA) using each patient's demographics, injury severity, and functional status. Patients were stratified into minimal, low, moderate, and high-risk cohort groups based on risk of <0.9%, 0.9-1.9%, 1.9-5%, and >5%. MAIN OUTCOME MEASUREMENTS/METHODS:length of stay, complications, disposition, readmission, and cost RESULTS:: 1278 patients (80.3%) sustained low-energy injuries and 314 patients (19.7%) sustained high-energy injuries. The average age was 73.8 ± 11.8 years. The mean length of hospital stay was 5.2 days with a significant difference between the STTGMA risk groups. This risk stratification between groups was also seen in complication rate, need for ICU/SDU care, percentage of patients discharged home, and readmission within 30-days. The mean total cost of admission for the minimal risk group was less than one-third that of the high-risk cohort. CONCLUSIONS:the STTGMA tool is able to risk stratify hospital quality outcome measures and cost. Thus, it is a valuable clinical tool for health care providers in identifying high-risk patients in efforts to continue to provide high-quality resource conscious care to orthopaedic trauma patients.

OBJECTIVES/OBJECTIVE:(1) To assess the correlation of psychosocial factors and long-term outcomes of proximal humerus fractures all in surgical repair; (2) to identify specific psychosocial factors with favorable and unfavorable outcomes; and (3) to assess the correlation between DSM-V mental health diagnoses and long-term Disabilities of Arm, Shoulder, and Hand (DASH) scores. DESIGN/METHODS:Prospective cohort study. SETTING/METHODS:Academic medical center. PATIENTS/METHODS:Patients were screened and identified on presentation to the emergency department or in the clinical office for inclusion in an institutional review board-approved registry. One hundred eighty-five proximal humerus fractures of 247 met inclusion criteria. INTERVENTION/METHODS:Surgical repair of proximal humerus fractures. MAIN OUTCOME MEASURE/METHODS:All patients were prospectively followed up and assessed for clinical and functional outcomes at latest follow-up visit (mean = 24.8 months) using the DASH questionnaires along with ranges of motion and pain level. Psychosocial factors at 3 months were obtained from the DASH survey. RESULTS:Concomitant diagnosis of depressed mood (P = 0.001), anxiety (P < 0.0005), low energy level (P = 0.003), and fatigue (P = 0.001) correlated significantly with poorer outcome. All 6 psychosocial factors correlated directly and significantly with pain at latest follow-up (P < 0.0005). Multiple regression analysis revealed that the strongest predictor of the overall DASH score was the extent of interference with social life (P = 0.001). CONCLUSION/CONCLUSIONS:Analysis demonstrated that psychological and social factors at 3 months postoperatively have a strong correlation with negative long-term (>1 year) outcomes after proximal humerus fixation. Clinicians may offer psychological support and encourage social support to these patients postoperatively to improve pain and treatment outcomes. LEVEL OF EVIDENCE/METHODS:Prognostic Level III.

OBJECTIVES/OBJECTIVE:To investigate the ability of a validated geriatric trauma risk prediction tool to stratify hospital quality metrics and inpatient cost for middle-aged and geriatric patients admitted from the ED for operative treatment of an ankle fracture. DESIGN/METHODS:Prospective cohort study SETTING:: Single Academic Medical Center PATIENTS:: Patients aged 55 and older who sustained a rotational ankle fracture and were treated operatively during their index hospitalization INTERVENTION:: Calculation of validated trauma triage score, Score for Trauma Triage in Geriatric and Middle Aged (STTGMA), using patient's demographic, injury severity, and functional status. Patients were stratified into groups based on scores to create a minimal-, low-, moderate-, and high-risk cohort. MAIN OUTCOME MEASUREMENTS/METHODS:length of stay, complications, need for ICU/SDU level care, discharge location, and index admission costs RESULTS:: Fifty ankle fracture patients met inclusion criteria. Mean length of stay was 7.8 ± 5.2 days with a significant difference among the four risk groups (4.6 day difference between low and high risk). 73.1% of minimal risk patients were discharged home compared to 0% of high-risk patients. There was no difference in complication rate or in need for ICU level care between groups. However, high-risk patients had a mean total inpatient cost two times greater than that of minimal risk patients. CONCLUSION/CONCLUSIONS:The STTGMA tool is able to meaningfully stratify older ankle fracture patients requiring operative fixation with regards to hospital quality metrics and cost. This information may allow for efficient targeted reductions in costs while optimizing outcomes. LEVEL OF EVIDENCE/METHODS:Prognostic, Level III.

BACKGROUND:Little evidence regarding the extent of recovery of radial nerve lesions with associated humerus trauma exists. The aim of this study is to examine the incidence and resolution of types of radial nerve palsy (RNP) in operative and nonoperative humeral shaft fracture populations. MATERIALS AND METHODS/METHODS:Radial nerve lesions were identified as complete (RNPc), which included motor and sensory loss, and incomplete (RNPi), which included sensory-only lesions. Charts were reviewed for treatment type, radial nerve status, RNP resolution time, and follow-up time. Descriptive statistics were used to document incidence of RNP and time to resolution. Independent-samples t-test was used to determine significant differences between RNP resolution time in operative and nonoperative cohorts. RESULTS:A total of 175 patients (77 operative, 98 nonoperative) with diaphyseal humeral shaft injury between 2007 and 2016 were identified and treated. Seventeen out of 77 (22.1%) patients treated operatively were diagnosed preoperatively with a radial nerve lesion. Two (2.6%) patients developed secondary RNPc postoperatively. Eight out of 98 (8.2%) patients presented with RNP postinjury for nonoperatively treated humeral shaft fracture. All patients who presented with either RNPc, RNPi, or iatrogenic RNP had complete resolution of their RNP. No statistically significant difference was found in recovery time when comparing the operative versus nonoperative RNPc, operative versus nonoperative RNPi, or RNPc versus RNPi patient groups. CONCLUSIONS:All 27 (100%) patients presenting with or developing radial nerve palsy in our study recovered. No patient required further surgery for radial nerve palsy. Radial nerve exploration in conjunction with open reduction and internal fixation (ORIF) appears to facilitate speedier resolution of RNP when directly compared with observation in nonoperative cases, although not statistically significantly so. These findings provide surgeons valuable information they can share with patients who sustain radial nerve injury with associated humerus shaft fracture or nonunion. LEVEL OF EVIDENCE/METHODS:Level III treatment study.

The purpose of this study was to evaluate whether patients with hip fractures receiving antiplatelet and direct oral anticoagulants treated within 48 hours of admission had worse surgical and clinical outcomes than those whose surgery was delayed more than 48 hours. Consecutive patients 55 years and older with an operatively treated hip fracture were analyzed. Patients receiving the following anticoagulants were included: antiplatelet drugs, factor Xa inhibitors, and direct thrombin inhibitors. Outcomes included surgical blood loss, procedure time, transfusion requirement, length of stay, complication rate, and need for intensive care unit or step-down unit level care. Patients who underwent surgery within 48 hours of presentation were compared with patients whose surgery was delayed more than 48 hours. Of 551 consecutive operative hip fracture patients, 78 (14.2%) were receiving the anticoagulant medications included in this study. Of these 78 patients, 58 had surgery within 48 hours and 20 had surgery after 48 hours. When comparing the early and delayed fixation cohorts, there was no difference in transfusion requirement, length of surgery, or blood loss. Type of anticoagulant made no difference in transfusion requirement, blood loss, or length of surgery. There was also no difference in the mean number of complications or in the need for intensive care unit or step-down unit level care. In this study, patients receiving antiplatelet therapy, factor Xa inhibitors, or direct thrombin inhibitors who underwent surgical fixation of their hip fracture within 48 hours of admission were at no higher risk for transfusion, increased surgical blood loss, longer operative time, or inpatient mortality.

OBJECTIVES/OBJECTIVE:Analyze the effectiveness of a BPCI (Bundle Payments for Care Improvement) initiative at a large urban medical center for hip fracture patients included in the bundle payment program with respect to improving patient outcomes and reducing cost DESIGN:: Retrospective cohort SETTING:: Single Academic Institution PATIENTS/PARTICIPANTS:: Patients discharged with the DRG codes 469-470 performed for hip fractures between July 2011 and September 2014 were evaluated. A BPCI initiative focused on optimizing care coordination, patient education, expectations, and minimizing post-acute facility and resource utilization was initiated in October 2013. Patient outcomes prior to the introduction of the BPCI initiative were compared to those who participated in the initiative. INTERVENTION/METHODS:Application of BPCI principles MAIN OUTCOME MEASURES:: length of stay, location of discharge, readmission within 90 days, and 90-day episode of care costs RESULTS:: Sixty-one patients received care prior to the initiative, and forty-four patients were treated with the initiative. The mean length of stay decreased from 6.8 to 5.3 days and the percentage of patients discharged home increased by nearly 10% with the introduction of the BPCI initiative (6.6% vs. 15.9%). There was a 13.1% reduction in total 90-day episode of care cost ($57,546 vs. $49,993, p=0.210) upon introduction of the initiative. There was no significant difference in readmission rate between the two cohorts. CONCLUSION/CONCLUSIONS:This study demonstrates the success of one such program for hip fracture arthroplasty patients aimed at care coordination and minimizing post-acute hospitalization facility care both with respect to improved patient outcomes and substantial cost reduction.
