RESUMEN
BACKGROUND: Studies evaluating surgical-site infection have had conflicting results with respect to the use of alcohol solutions containing iodine povacrylex or chlorhexidine gluconate as skin antisepsis before surgery to repair a fractured limb (i.e., an extremity fracture). METHODS: In a cluster-randomized, crossover trial at 25 hospitals in the United States and Canada, we randomly assigned hospitals to use a solution of 0.7% iodine povacrylex in 74% isopropyl alcohol (iodine group) or 2% chlorhexidine gluconate in 70% isopropyl alcohol (chlorhexidine group) as preoperative antisepsis for surgical procedures to repair extremity fractures. Every 2 months, the hospitals alternated interventions. Separate populations of patients with either open or closed fractures were enrolled and included in the analysis. The primary outcome was surgical-site infection, which included superficial incisional infection within 30 days or deep incisional or organ-space infection within 90 days. The secondary outcome was unplanned reoperation for fracture-healing complications. RESULTS: A total of 6785 patients with a closed fracture and 1700 patients with an open fracture were included in the trial. In the closed-fracture population, surgical-site infection occurred in 77 patients (2.4%) in the iodine group and in 108 patients (3.3%) in the chlorhexidine group (odds ratio, 0.74; 95% confidence interval [CI], 0.55 to 1.00; P = 0.049). In the open-fracture population, surgical-site infection occurred in 54 patients (6.5%) in the iodine group and in 60 patients (7.3%) in the chlorhexidine group (odd ratio, 0.86; 95% CI, 0.58 to 1.27; P = 0.45). The frequencies of unplanned reoperation, 1-year outcomes, and serious adverse events were similar in the two groups. CONCLUSIONS: Among patients with closed extremity fractures, skin antisepsis with iodine povacrylex in alcohol resulted in fewer surgical-site infections than antisepsis with chlorhexidine gluconate in alcohol. In patients with open fractures, the results were similar in the two groups.

INTRODUCTION: Patient-centered treatment and research should focus on the outcomes that matter to patients. The primary aim of this study was to determine the outcome preferences of patients after musculoskeletal trauma. The secondary aim was to identify discrepancies between outcome preferences of surgeons and patients. METHODS: A Best-worst scaling choice experiment survey was administered to patients with operative lower extremity injuries and orthopaedic surgeons who take trauma call. Participants completed 13 choice sets of 3 randomly-ordered outcomes, including: a full recovery (back to normal) without any problems; a problem that requires additional surgery or hospital stay versus medication or treatment in clinic/emergency department; minimal to moderate versus severe pain for 6 weeks; need for crutches/walker versus wheelchair for 6-12 weeks; being unable to work for 6-12 weeks; requiring 2-4 weeks in a facility; a perfect versus poor or worst-possible EuroQol 5 Dimension (EQ-5D) score at 1 year; and death. Within each set, participants ranked their "most-preferred" to "least-preferred" outcomes. Responses were aggregated to calculate the relative importance, or marginal utility, of each outcome stratified by respondent type. RESULTS: Fifty-five patients and 65 surgeons participated. The most preferred outcome for patients and surgeons was a full recovery (back to normal) without any problems, followed by minimal to moderate pain for 6 weeks and a perfect EQ-5D score. The least preferred outcomes were death and the worst EQ-5D score, which had similar marginal utility, followed by a poor EQ-5D score and a problem that needs another surgery or stay at a hospital, which also had similar marginal utility. Surgeons, in comparison to patients, assigned a higher marginal utility to perfect EQ-5D scores at one year (3.55 vs. 2.03; p < 0.0001) and a 2-4 week stay in a facility (0.52 vs. -0.21; p = 0.001), and a lower marginal utility to severe pain for 6 weeks (-0.58 vs. -0.08; p = 0.04) and a poor EQ-5D score (-1.88 vs. -1.03; p = 0.02). CONCLUSIONS: A full recovery (back to normal) without any problems was the most-preferred outcome for both patients and surgeons. Patient-centered care and research should focus on both patients' return to baseline and the avoidance of complications. LEVEL OF EVIDENCE: N/A.

Introduction: When considering treatment options for geriatric patients with lower extremity fractures, little is known about which outcomes are prioritized by patients. This study aimed to determine the patient preferences for outcomes after a geriatric lower extremity fracture. Materials and Methods: We administered a discrete choice experiment survey to 150 patients who were at least 60 years of age and treated for a lower extremity fracture at a Level I trauma center. The discrete choice experiment presented study participants with 8 sets of hypothetical outcome comparisons, including joint preservation (yes or no), risk of reoperation at 6 months and 24 months, postoperative weightbearing status, disposition, and function as measured by return to baseline walking distance. We estimated the relative importance of these potential outcomes using multinomial logit modeling. Results: The strongest patient preference was for maintained function after treatment (59%, P < .001), followed by reoperation within 6 months (12%, P < .001). Although patients generally favored joint preservation, patients were willing to change their preference in favor of joint replacement if it increased function (walking distance) by 13% (SE, 66%). Reducing the short-term reoperation risk (12%, P < .001) was more important to patients than reducing long-term reoperation risk (4%, P = .33). Disposition and weightbearing status were lesser priorities to patients (9%, P < .001 and 7%, P < .001, respectively). Discussion: After a lower extremity fracture, geriatric patients prioritized maintained walking function. Avoiding short-term reoperation was more important than avoiding long-term reoperation. Joint preservation through fracture fixation was the preferred treatment of geriatric patients unless arthroplasty or arthrodesis provides a meaningful functional benefit. Hospital disposition and postoperative weightbearing status were less important to patients than the other included outcomes. Conclusions: Geriatric patients strongly prioritize function over other outcomes after a lower extremity fracture.
RESUMEN
Objectives: To determine venous thromboembolism (VTE) testing patterns in an orthopaedic trauma population and to evaluate for differences in VTE surveillance by prophylaxis regimen through a secondary analysis of the ADAPT trial. Design: Prospective randomized trial. Setting: Level I trauma center. Patients: Three hundred twenty-nine adult (18 years and older) trauma patients presenting with an operative extremity fracture proximal to the metatarsals/carpals or any pelvic or acetabular fracture requiring VTE prophylaxis. Intervention: VTE imaging studies recorded within 90 days post injury. Main Outcome Measurements: Percentage of patients tested for VTE were compared between treatment groups using Fisher's exact test. Subsequently, multivariable regression was used to determine patient factors significantly associated with risk of receiving a VTE imaging study. Results: Sixty-seven patients (20.4%) had VTE tests ordered during the study period. Twenty (29.9%) of these 67 patients with ordered VTE imaging tests had a positive finding. No difference in proportion of patients tested for VTE by prophylaxis regimen (18.8% on aspirin vs. 22.0% on LMWH, P = 0.50) was observed. Factors associated with increased likelihood of VTE testing included White race (adjusted odds ratio [aOR]: 2.61, 95% CI: 1.26-5.42), increased Injury Severity Score (aOR for every 1-point increase: 1.10, 95% CI: 1.05-1.15), and lower socioeconomic status based on the Area Deprivation Index (aOR for every 10-point increase: 1.14, 95% CI: 1.00-1.30). Conclusions: VTE surveillance did not significantly differ by prophylaxis regimen. Patient demographic factors including race, injury severity, and socioeconomic status were associated with differences in VTE surveillance. Level of Evidence: Level I, Therapeutic.
RESUMEN
INTRODUCTION: Financial toxicity is highly prevalent in patients after an orthopaedic injury. However, little is known regarding the conditions that promote and protect against this financial distress. Our objective was to understand the factors that cause and protect against financial toxicity after a lower extremity fracture. METHODS: A qualitative study was conducted using semi-structured interviews with 20 patients 3 months after surgical treatment of a lower extremity fracture. The interviews were audio-recorded, transcribed verbatim, and analyzed using thematic analysis to identify themes and subthemes. Data saturation occurred after 15 interviews. The percentage of patients who described the identified themes are reported. RESULTS: A total of 20 patients (median age, 44 years [IQR, 38 to 58]; 60% male) participated in the study. The most common injury was a distal tibia fracture (n = 8; 40%). Eleven themes that promoted financial distress were identified, the most common being work effects (n = 14; 70%) and emotional health (n = 12; 60%). Over half (n = 11; 55%) of participants described financial toxicity arising from an inability to access social welfare programs. Seven themes that protected against financial distress were also identified, including insurance (n = 17; 85%) and support from friends and family (n = 17; 85%). Over half (n = 13; 65%) of the participants discussed the support they received from their healthcare team, which encompassed expectation setting and connections to financial aid and other services. Employment protection and workplace flexibility were additional protective themes. CONCLUSION: This qualitative study of orthopaedic trauma patients found work and emotional health-related factors to be primary drivers of financial toxicity after injury. Insurance and support from friends and family were the most frequently reported protective factors. Many participants described the pivotal role of the healthcare team in establishing recovery expectations and facilitating access to social welfare programs.

BACKGROUND: The purpose of this study was to externally validate a predictive score for fracture-related infections, establishing generalizability for absolute and relative risk of infection in the setting of orthopedic fracture surgery. MATERIALS AND METHODS: This was a retrospective, case-control study performed at a level I academic trauma center that included 147 patients with fracture-related infection in the study group and 300 control patients. We analyzed the same 8 independent predictors of fracture-related infection cited by a previous study. We then used the area under the receiver operating characteristics curve (AUC) to compare the derivation and validation cohorts. The validation and derivation cohorts were then compared by grouping patients into 4 strata of Wise score groups. This allowed for comparison of AUC and risk of fracture-related infection in our institution with those in the previously studied institution. RESULTS: The resulting data yielded an AUC (0.74) nearly identical to that of the previously studied institution. It was also found that the relative risk of infection correlated with the Wise score in the same way the initial model did with the absolute risks being similar. CONCLUSION: The previous predictive model was externally validated and shown to be generalizable to a different patient population. The relative risk of a fracture-related infection can be determined using this scoring model preoperatively with the goal of aiding in patient counseling and surgical decision-making, giving a quantitative value to patient risk factors.

RESUMEN
"All or none" approaches to the use of contact precautions for methicillin-resistant Staphylococcus aureus (MRSA) both fail to recognize that transmission risk varies. This qualitative study assessed healthcare personnel perspectives regarding the feasibility of a risk-tailored approach to use contact precautions for MRSA more strategically in the acute care setting.
RESUMEN
OBJECTIVE: This study was undertaken to evaluate hip fracture simulator training and orthopedic resident skill attainment. We hypothesized that after 6 training sessions, improvement in post-training scores in junior residents would exceed that of senior residents and that senior residents would attain expert level proficiency sooner. DESIGN: Thirty orthopedic residents from a single institution completed 6 training sessions. Sessions included a pretest, 9 training modules, and post-test. An expert score was obtained from the average scores of 8 trauma fellows and attending orthopedic traumatologists. The primary outcome measure was overall score. SETTING: A single academic institution. PARTICIPANTS: Orthopedic residents (postgraduate years [PGYs] 1-5). RESULTS: Twenty-six residents completed the study. The mean overall post-training score was 87% of the expert level. Factors associated with post-training score changes were additional training sessions (4.2% improvement [p < 0.01]), time between training sessions (0.3% decrease [pâ¯=â¯0.05]) and PGY5 class (12.1% improvement [pâ¯=â¯0.03]). Fifty-four percent of residents attained the expert overall score. Expert score attainment was not associated with an additional year of training or case log volume. Post-training scores plateaued for the PGY1s and showed linear improvement for the PGY5s. CONCLUSIONS: Differences in trends between training levels suggest this simulator is a useful adjunct to a 5-year orthopedic residency training program.

OBJECTIVE: To quantify work impairment and economic losses due to lost employment, lost work time (absenteeism), and lost productivity while working (presenteeism) after a lateral compression pelvic ring fracture. Secondarily, productivity loss of patients treated with surgical fixation versus nonoperative management was compared. DESIGN: Secondary analysis of a prospective, multicenter trial. SETTING: Two level I academic trauma centers. PATIENT SELECTION CRITERIA: Adult patients with a lateral compression pelvic fracture (OTA/AO 61-B1/B2) with a complete posterior pelvic ring fracture and less than 10 mm of initial displacement. Excluded were patients who were not working or non-ambulatory before their pelvis fracture or who had a concomitant spinal cord injury. OUTCOME MEASURES AND COMPARISONS: Work impairment, including hours lost to unemployment, absenteeism, and presenteeism, measured by Work Productivity and Activity Impairment assessments in the year after injury. Results after non-operative and operative treatment were compared. RESULTS: Of the 64 included patients, forty-seven percent (30/64) were treated with surgical fixation, and 53% (30/64) with nonoperative management. 63% returned to work within 1 year of injury. Workers lost an average of 67% of a 2080-hour average work year, corresponding with $56,276 in lost economic productivity. Of the 1395 total hours lost, 87% was due to unemployment, 3% to absenteeism, and 10% to presenteeism. Surgical fixation was associated with 27% fewer lost hours (1155 vs. 1583, P = 0.005) and prevented $17,266 in average lost economic productivity per patient compared with nonoperative management. CONCLUSIONS: Lateral compression pelvic fractures are associated with a substantial economic impact on patients and society. Surgical fixation reduces work impairment and the corresponding economic burden. LEVEL OF EVIDENCE: Economic Level IV. See Instructions for Authors for a complete description of levels of evidence.

BACKGROUND: Current guidelines recommend low-molecular-weight heparin for thromboprophylaxis after orthopaedic trauma. However, recent evidence suggests that aspirin is similar in efficacy and safety. To understand patients' experiences with these medications, we compared patients' satisfaction and out-of-pocket costs after thromboprophylaxis with aspirin versus low-molecular-weight heparin. METHODS: This study was a secondary analysis of the PREVENTion of CLots in Orthopaedic Trauma (PREVENT CLOT) trial, conducted at 21 trauma centers in the U.S. and Canada. We included adult patients with an operatively treated extremity fracture or a pelvic or acetabular fracture. Patients were randomly assigned to receive 30 mg of low-molecular-weight heparin (enoxaparin) twice daily or 81 mg of aspirin twice daily for thromboprophylaxis. The duration of the thromboprophylaxis, including post-discharge prescription, was based on hospital protocols. The study outcomes included patient satisfaction with and out-of-pocket costs for their thromboprophylactic medication measured on ordinal scales. RESULTS: The trial enrolled 12,211 patients (mean age and standard deviation [SD], 45 ± 18 years; 62% male), 9725 of whom completed the question regarding their satisfaction with the medication and 6723 of whom reported their out-of-pocket costs. The odds of greater satisfaction were 2.6 times higher for patients assigned to aspirin than those assigned to low-molecular-weight heparin (odds ratio [OR]: 2.59; 95% confidence interval [CI]: 2.39 to 2.80; p < 0.001). Overall, the odds of incurring any out-of-pocket costs for thromboprophylaxis medication were 51% higher for patients assigned to aspirin compared with low-molecular-weight heparin (OR: 1.51; 95% CI: 1.37 to 1.66; p < 0.001). However, patients assigned to aspirin had substantially lower odds of out-of-pocket costs of at least $25 (OR: 0.15; 95% CI: 0.12 to 0.18; p < 0.001). CONCLUSIONS: Use of aspirin substantially improved patients' satisfaction with their medication after orthopaedic trauma. While aspirin use increased the odds of incurring any out-of-pocket costs, it protected against costs of ≥$25, potentially improving health equity for thromboprophylaxis.

OBJECTIVES: To estimate the generalizability of treatment effects observed in the VANCO trial to a broader population of patients with tibial plateau or pilon fractures. METHODS: Design and Setting: Clinical trial data from 36 United States trauma centers and Trauma Quality Programs registry data from more than 875 Level I-III trauma centers in the United States and Canada.Patient Selection Criteria: Patients enrolled in the VANCO trial treated with intrawound vancomycin powder from January 2015 to June 2017 and 31,924 VANCO-eligible TQP patients admitted in 2019 with tibial plateau and pilon fractures.Outcome Measure and Comparisons: Deep surgical site infection and gram-positive deep surgical site infection estimated in the TQP sample weighed by the inverse probability of trial participation. RESULTS: The 980 patients in the VANCO trial were highly representative of 31,924 TQP VANCO-eligible patients (Tipton generalizability index 0.96). It was estimated that intrawound vancomycin powder reduced the odds of deep surgical infection by odds ratio (OR) = 0.46 (95% confidence interval [CI] 0.25-0.86) and gram-positive deep surgical infection by OR = 0.39 (95% CI, 0.18-0.84) within the TQP sample of VANCO-eligible patients. For reference, the trial average treatment effects for deep surgical infection and gram-positive deep surgical infection were OR = 0.60 (95% CI, 0.37-0.98) and OR = 0.44 (95% CI, 0.23-0.80), respectively. CONCLUSIONS: This generalizability analysis found that the inferences of the VANCO trial generalize and might even underestimate the effects of intrawound vancomycin powder when observed in a wider population of patients with tibial plateau and pilon fractures. LEVEL OF EVIDENCE: Therapeutic Level III. See Instructions for Authors for a complete description of levels of evidence.

OBJECTIVE: To identify technical factors associated with nonunion after operative treatment with lateral locked plating. DESIGN: Retrospective cohort study. SETTING: Ten Level I trauma centers. PATIENT SELECTION CRITERIA: Adult patients with supracondylar distal femur fractures (OTA/AO type 33A or C) treated with lateral locked plating from 2010 through 2019. OUTCOME MEASURES AND COMPARISONS: Surgery for nonunion stratified by risk for nonunion. RESULTS: The cohort included 615 patients with supracondylar distal femur fractures. The median patient age was 61 years old (interquartile range: 46 -72years) and 375 (61%) were female. Observed were nonunion rates of 2% in a low risk of nonunion group (n = 129), 4% in a medium-risk group (n = 333), and 14% in a high-risk group (n = 153). Varus malreduction with an anatomic lateral distal femoral angle greater than 84 degrees, was associated with double the odds of nonunion compared to those without such varus [odds ratio, 2.1; 95% confidence interval (CI), 1.1-4.2; P = 0.03]. Malreduction by medial translation of the articular block increased the odds of nonunion, with 30% increased odds per 4 mm of medial translation (95% CI, 1.0-1.6; P = 0.03). Working length increased the odds of nonunion in the medium risk group, with an 18% increase in nonunion per 10-mm increase in working length (95% CI, 1.0-1.4; P = 0.01). Increased proximal screw density was protective against nonunion (odds ratio, 0.71; 95% CI, 0.53-0.92; P = 0.02) but yielded lower mRUST scores with each 0.1 increase in screw density associated with a 0.4-point lower mRUST (95% CI, -0.55 to -0.15; P < 0.001). Lateral plate length and type of plate material were not associated with nonunion. ( P > 0.05). CONCLUSIONS: Malreduction is a surgeon-controlled variable associated with nonunion after lateral locked plating of supracondylar distal femur fractures. Longer working lengths were associated with nonunion, suggesting that bridge plating may be less likely to succeed for longer fractures. LEVEL OF EVIDENCE: Therapeutic Level III.
