OBJECTIVES/OBJECTIVE:To identify which factors are predictive of surgical site infection in upper extremity fractures, and to assess whether the timing of operative debridement influences infection risk. DESIGN/METHODS:Retrospective database review. SETTING/METHODS:Hospitals participating in the American College of Surgeons National Surgical Quality Improvement Program (NSQIP) database. PATIENTS/METHODS:Patients in the NSQIP database with fractures involving the upper extremity. INTERVENTION/METHODS:Surgical management of upper extremity fracture, including operative debridement for open injuries. MAIN OUTCOME MEASUREMENTS/METHODS:Surgical site infection, including both superficial and deep infections. RESULTS:A total of 22,578 patients were identified, including 1298 patients with open injuries (5.7% of total). The overall wound infection rate was 0.79%. Patients with open injuries were found to have a higher incidence of infection compared with those with closed injuries (1.7% vs. 0.7%, P < 0.001). Independent risk factors for 30-day infection included open fracture diagnosis, obesity, smoking, and American Society of Anesthesiolgists class >2 (all P < 0.05). Of patients with open fractures, 79.7% were taken expediently to the operating room. The rate of infection did not differ based on whether surgery was performed expediently or not (1.8% vs. 1.1%, P = 0.431). CONCLUSIONS:Based on an analysis of the NSQIP database, the overall risk of surgical site infection following intervention for open or closed upper extremity fractures remains low. Risk factors for infection include open injury, obesity, and cigarette smoking. There was no difference in the infection rate based on the urgency of operative debridement. LEVEL OF EVIDENCE/METHODS:Prognostic Level III. See Instructions for Authors for a complete description of levels of evidence.

AIMS/OBJECTIVE:Tibial plateau fractures are serious injuries about the knee that have the potential to affect patients' long-term function. To our knowledge, this is the first study to use patient-reported outcomes (PROs) with a musculoskeletal focus to assess the long-term outcome, as compared to a short-term outcome baseline, of tibial plateau fractures treated using modern techniques. METHODS:-test. RESULTS:Patient-reported functional outcomes as assessed by overall SMFA were statistically significantly improved at five years (p < 0.001) compared with one-year data from the same patients. Patients additionally reported an improvement in the Standardized Mobility Index (p < 0.001), Standardized Emotional Index (p < 0.001), as well as improvement in Standardized Bothersome Index (p = 0.003) between the first year and latest follow-up. Patient-reported pain and knee ROM were similar at five years to their one-year follow-up. In total, 15 of the patients had undergone subsequent orthopaedic surgery for their knees at the time of most recent follow-up. Of note, only one patient had undergone knee arthroplasty following plateau fixation related to post-traumatic osteoarthritis (OA). CONCLUSION/CONCLUSIONS:2020;102-B(5):632-637.

OBJECTIVES/OBJECTIVE:To evaluate the causes of 30-day readmissions following orthopedic trauma surgery and classify them based on their relation to the index admission. DESIGN/METHODS:Retrospective chart review. SETTING/METHODS:One large, academic medical center. PARTICIPANTS/METHODS:Patients admitted to a large, academic medical center for a traumatic fracture injury over a nine-year period. INTERVENTION/METHODS:Assignment of readmission classification. MAIN OUTCOME MEASUREMENTS/METHODS:Readmissions within 30 days of discharge were identified and classified into: orthopedic complications; medical complications; and non-complications. A chi-square test was performed to assess any difference in the proportion of readmissions between the hospital-reported readmission rate and the orthopedic complication readmission rate. RESULTS:1,955 patients who were admitted between 2011-2018 for an acute orthopedic trauma fracture injury were identified. Eighty-nine patients were readmitted within 30 days of discharge with an overall readmission rate of 4.55%. Within the 30-day readmission cohort, 30 (33.7%) were the direct result of orthopedic treatment complications, 36 (40.4%) were unrelated medical conditions, and 23 (25.8%) were non-complications. Thus, the readmission rate directly due to orthopedic treatment complications was 1.53%. A chi-square test of homogeneity revealed a statistically significant difference between the hospital-reported readmission rate and the orthopedic-treatment complication readmission rate, p < .0005. CONCLUSION/CONCLUSIONS:The use of 30-day readmissions as a measure of hospital quality of care overreports the number of preventable readmissions and penalizes surgeons and hospitals for caring for patients with less optimal health. LEVEL OF EVIDENCE/METHODS:Diagnostic Level III.

Introduction/UNASSIGNED:Rising costs of post-acute care facilities for both the patient and payers make discharge home after hospital stay, with or without home help, a favorable alternative for all parties. Our objectives were to assess the effect of marital status, a large source of social support for many, on disposition following hospital stay. Methods/UNASSIGNED:Patients were prospectively entered into an institutional review board-approved, trauma database at a large, academic medical center. Patients aged 55 years or older with any fracture injury between 2014 and 2017 were included. Retrospectively, their relationship status was recorded through review of patient records. A status of "married" was separated from those with a status self-reported as "single," "divorced," or "widowed." Multinomial logistic regression was used to assess whether discharge location differs by marital status while controlling for demographics and injury characteristics. Results/UNASSIGNED:Of 1931 patients, 8.3% were divorced, 29.9% were single, 20.0% were widowed, and 41.8% were married. There was a significant correlation between discharge disposition and marital status. Single patients had 1.71 times, and widowed patients had 1.80 times, the odds of being discharged to a nursing home, long-term care facility, or skilled nursing facility compared to married patients after controlling for age, gender, Score for Trauma Triage in the Geriatric and Middle-Aged score, and insurance type. Additionally, single and widowed patients experienced 1.36 and 1.30 times longer length of hospital stay than their married counterparts, respectively. Discussion/UNASSIGNED:Patients who are identified as "single" or "widowed" should have early social work intervention to establish clear discharge expectations. Early intervention in this way would allow time for contact with close, living relatives or friends who may be able to provide sufficient support so that patients can return home. Increasing home discharge rates for these patients would reduce lengths of hospital stay and reduce post-acute care costs for both patient and payers without materially altering unplanned readmission rates.

Introduction/UNASSIGNED:This study sought to investigate whether a validated trauma triage risk assessment tool can predict time to surgery and delay to surgery. Materials and Methods/UNASSIGNED:Patients aged 55 and older who were admitted for operative repair or arthroplasty of a hip fracture over a 3-year period at a single academic institution were included. Risk quartiles were constructed using Score for Trauma Triage in the Geriatric and Middle-Aged (STTGMA) calculations. Negative binomial and multivariable logistic regression were used to evaluate time to surgery and delay to surgery, respectively. Pairwise comparisons were performed to evaluate 30-day mortality rates and demonstrate the effectiveness of the STTGMA tool in triaging mortality risk. Results/UNASSIGNED:= .046). Discussion/UNASSIGNED:Patients in higher STTGMA quartiles encountered longer time to surgery, greater operative delays, and higher 30-day mortality. Conclusion/UNASSIGNED:Score for Trauma Triage in the Geriatric and Middle-Aged can quickly identify hip fracture patients at risk for a delay to surgery and may allow treatment teams to optimize surgical timing by proactively targeting these patients. Level of Evidence/UNASSIGNED:Prognostic Level III.

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.

Purpose/UNASSIGNED:To characterize the volume and variation in orthopedic consults and surgeries that took place during a period of social distancing and pandemic. Methods/UNASSIGNED:All orthopedic consults and surgeries at an urban level 1 trauma center from 3/22/20-4/30/2020 were retrospectively reviewed (the social distancing period). Data from the same dates in 2019 were reviewed for comparison. Age, gender, Score for Trauma Triage in the Geriatric and Middle Aged (STTGMA) score and injury type were queried. Operating room data collected included: type of surgery performed, inpatient or outpatient status, and if the cases were categorized as elective, trauma or infectious cases. Results/UNASSIGNED:Compared to 2019, there was a 48.3% decrease in consult volume in 2020. The 2020 population was significantly older (44.0 vs 52.6 years-old, p = 0.001) and more male (65% vs 35%, p = 0.021). There were 23 COVID positive patients, 10 of which died within the collection period. Consult distribution dramatically changed, with decreases in ankle fractures, distal radius fractures and proximal humerus fractures of 76.5%, 77.4% and 55.0%, respectively. However, there was no significant difference in volume of hip, tibial shaft and femoral shaft fractures (p > 0.05). In 2020, there was a 41.4% decrease in operating room volume, no elective cases were performed, and cases were primarily trauma related. Conclusions/UNASSIGNED:During a period of pandemic and social distancing, the overall volume of orthopedic consults and surgeries significantly declined. However, hip fracture volume remained unchanged. Patients presenting with orthopedic injuries were older, and at higher risk for inpatient mortality.

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.
