RESUMEN

¼ Nuclear imaging techniques, including bone scintigraphy, labeled leukocyte scintigraphy, positron emission tomography (PET), and single-photon emission computed tomography (SPECT) combined with computed tomography (CT), have wide applications in orthopaedics for evaluating trauma, painful total joint arthroplasty, musculoskeletal infection, and orthopaedic oncology.¼ Three-phase bone scintigraphy is a first-line, highly sensitive nuclear medicine study for evaluating orthopaedic pathology when initial studies are inconclusive. However, its specificity is limited, and findings may be falsely positive for up to 2 years after total joint arthroplasty because of physiologic bone remodeling.¼ Labeled leukocyte scintigraphy or gallium scintigraphy can improve diagnostic accuracy in patients with a positive bone scan and suspected musculoskeletal or periprosthetic joint infection.¼ 18-Fluorodeoxyglucose PET/CT demonstrates high sensitivity and specificity for diagnosing bone neoplasms, infections, and metabolic disorders. Emerging PET/magnetic resonance imaging technology offers reduced radiation exposure and greater soft-tissue detail but presents technical and cost challenges.¼ SPECT/CT provides valuable functional and anatomic detail for characterizing the extent and location of bone pathology, serving as an important adjunct to other imaging modalities.¼ Ultimately, the choice of nuclear imaging modality should consider the specific clinical context, diagnostic accuracy, impact on management, and cost-effectiveness on a case-by-case basis.

RESUMEN

INTRODUCTION: Social media offers physicians marketing opportunities previously unavailable. We sought to evaluate social media use and its correlation with public rankings among Association of Hip and Knee Surgeons members. METHODS: A list of members and demographics was collected. Social media sites were reviewed for each surgeon, and a score was calculated based on active use. The US News and World Report (NWR) was used to determine rating and number of reviews. The Spearman correlation coefficient and independent samples t-test were used to measure correlation and compare means between the groups, respectively. RESULTS: A total of 2436 members were analyzed. The average social media score was 4.14. The average US NWR score was 4.25. A strong correlation was observed between social media and US NWR scores (r = 0.74, P < 0.01) but not with the number of reviews (r = 0.40, P = 0.17). A strong association with US NWR rating (r = 0.74, P = 0.04) and a weak correlation with the total number of reviews (r = 0.61, P = 0.06) were found. CONCLUSIONS: Social media use is correlated with US NWR scores. Association of Hip and Knee Surgeons members may be underutilizing social media for the promotion of their practices. Future studies are needed to evaluate whether it affects patient volume and outcomes.

RESUMEN

OBJECTIVES: To identify what transportation barriers pediatric patients face when traveling to a major metropolitan orthopaedic center, how these barriers affect care, and what changes can be made to address this issue. STUDY DESIGN: A cross-sectional transportation survey was administered to 107 caregivers of patients being seen in the orthopaedic clinic at a tertiary children's hospital in a large metropolitan area. Using logistic regression analysis, we compared socioeconomic characteristics, transportation methods, and scheduling practices among caregivers who reported missing at least one visit in the past and those who reported never missing a visit. RESULTS: 13% (14/108) of caregivers reported missing one or more past visits due to late arrival or transportation issues. Families that traveled more than 45 minutes to clinic (P = 0.04), waited more than one week to schedule a visit (P = 0.002), or reported difficulty scheduling a visit (P = 0.02) were significantly more likely to have a history of nonattendance. In addition, patients who were nonambulatory (P = 0.007), used a mobility device (P = 0.007), or were non-White (P < 0.05) were significantly more likely to have missed a visit. CONCLUSION: Travel time, difficult or delayed scheduling, and patient ambulatory status were all associated with missing orthopaedic clinic visits although other socioeconomic factors were not related. Interventions to improve orthopaedic clinic attendance should focus on promoting accessibility for patients with mobility limitations and encouraging simple and timely scheduling practices.

RESUMEN

BACKGROUND: ChatGPT is a natural language processing model developed by OpenAI, which can be iteratively updated and optimized to accommodate the changing and complex requirements of human verbal communication. OBJECTIVE: The study aimed to evaluate ChatGPT's accuracy in answering orthopedics-related multiple-choice questions (MCQs) and assess its short-term effects as a learning aid through a randomized controlled trial. In addition, long-term effects on student performance in other subjects were measured using final examination results. METHODS: We first evaluated ChatGPT's accuracy in answering MCQs pertaining to orthopedics across various question formats. Then, 129 undergraduate medical students participated in a randomized controlled study in which the ChatGPT group used ChatGPT as a learning tool, while the control group was prohibited from using artificial intelligence software to support learning. Following a 2-week intervention, the 2 groups' understanding of orthopedics was assessed by an orthopedics test, and variations in the 2 groups' performance in other disciplines were noted through a follow-up at the end of the semester. RESULTS: ChatGPT-4.0 answered 1051 orthopedics-related MCQs with a 70.60% (742/1051) accuracy rate, including 71.8% (237/330) accuracy for A1 MCQs, 73.7% (330/448) accuracy for A2 MCQs, 70.2% (92/131) accuracy for A3/4 MCQs, and 58.5% (83/142) accuracy for case analysis MCQs. As of April 7, 2023, a total of 129 individuals participated in the experiment. However, 19 individuals withdrew from the experiment at various phases; thus, as of July 1, 2023, a total of 110 individuals accomplished the trial and completed all follow-up work. After we intervened in the learning style of the students in the short term, the ChatGPT group answered more questions correctly than the control group (ChatGPT group: mean 141.20, SD 26.68; control group: mean 130.80, SD 25.56; P=.04) in the orthopedics test, particularly on A1 (ChatGPT group: mean 46.57, SD 8.52; control group: mean 42.18, SD 9.43; P=.01), A2 (ChatGPT group: mean 60.59, SD 10.58; control group: mean 56.66, SD 9.91; P=.047), and A3/4 MCQs (ChatGPT group: mean 19.57, SD 5.48; control group: mean 16.46, SD 4.58; P=.002). At the end of the semester, we found that the ChatGPT group performed better on final examinations in surgery (ChatGPT group: mean 76.54, SD 9.79; control group: mean 72.54, SD 8.11; P=.02) and obstetrics and gynecology (ChatGPT group: mean 75.98, SD 8.94; control group: mean 72.54, SD 8.66; P=.04) than the control group. CONCLUSIONS: ChatGPT answers orthopedics-related MCQs accurately, and students using it excel in both short-term and long-term assessments. Our findings strongly support ChatGPT's integration into medical education, enhancing contemporary instructional methods.

RESUMEN

BACKGROUND: Assessment of orthopaedic surgery trainees is traditionally based on subjective evaluation by faculty. The recent push for value-based health care has placed a premium on improving patient outcomes. As a result, surgical training evaluations for orthopaedic trainees are evolving to include more objective measures to evaluate competency. PURPOSE: To develop and subsequently demonstrate the efficacy of a novel surgical skills assessment for orthopaedic sports medicine fellows. STUDY DESIGN: Case series; Level of evidence, 4. METHODS: A team of 14 fellowship-trained orthopaedic sports medicine surgeons developed objective scoring rubrics for anterior cruciate ligament reconstruction (ACLR) and rotator cuff repair (RCR) using a modified Delphi process. Rubrics were designed based on 10 surgical steps with a grading scale (1-5) based on core competencies with a maximum summative score of 50. Fourteen orthopaedic fellows across a regionally diverse group of sports medicine-accredited fellowship programs were invited to complete both an ACLR and RCR in a surgical skills laboratory at the beginning and end of their fellowship year. Individual surgical steps, overall performance, and total procedure time were evaluated by a single sports medicine surgeon for both sessions. RESULTS: Thirteen of 14 fellows completed both pre- and post-fellowship assessments. For the ACLR procedure, the pre-fellowship mean summative score was 25.4 (SD, 4.4) and the post-fellowship mean summative score was 38.6 (SD, 4.1), which was a statistically significant improvement (P < .001). For the RCR procedure, the pre-fellowship mean summative score was 26.6 (SD, 5.4) and the post-fellowship mean summative score was 38.8 (SD, 4.3), which was also a statistically significant improvement (P < .001). The mean time to completion for the ACLR procedure was 82.3 minutes (SD, 4.3 minutes) pre-fellowship, which improved to 69.7 minutes (SD, 11.6 minutes) post-fellowship (P = .002). The mean time to completion for the RCR procedure was 85.5 minutes (SD, 5.0 minutes) pre-fellowship, which improved to 76.4 minutes (SD, 7.0 minutes) post-fellowship (P < .001). CONCLUSION: This surgical skills program represents the first standardized and reproducible instrument for the evaluation of 2 arthroscopic sports medicine procedures in the United States. Orthopaedic sports medicine fellows improved significantly in aggregate over their fellowship year with regard to the ACLR and RCR. The described program has the potential to serve as both a training tool and formal orthopaedic sports medicine fellow assessment.

RESUMEN

INTRODUCTION: This study assesses the accessibility and nature of parental leave policies during orthopaedic surgery residency training after implementation of the Accreditation Council for Graduate Medical Education (GME) mandate for 6 weeks of paid parental leave effective July of 2022. MATERIALS AND METHODS: An audit of orthopaedic surgery residency and affiliated GME websites was conducted to assess the accessibility of parental leave policies during the 2023-2024 academic year. Details on length of leave and nature of renumeration during the leave were recorded. Bivariate analyses were conducted to determine residency program characteristics associated with the accessibility of a parental leave policy. Results were compared with a previous analysis during the 2017-2018 academic year. RESULTS: A total of 200 residency programs were evaluated, and 152 had parental leave policies (76.0%). Compared with 2017 to 2018, a similar percentage of parental leave policies were accessible on residency program websites (3.0% vs. 2.0%, P = 0.777) but fewer were accessible on GME websites (55.5% vs. 80.7%, P < 0.001). More contemporary policies were obtained from program coordinators (18.5% vs. 7.2%, P = 0.003), and more were not available (24.0% vs. 9.0%, P < 0.001). Most policies offered renumeration (86.7%) and leave for 6 weeks in length (75.0%). A higher prevalence of parental leave policy accessibility was found among orthopaedic residency programs with university affiliation (P < 0.001), more faculty members (P = 0.008) and residents (P = 0.017), a higher percentage of female faculty (P = 0.008), affiliation with a top 50 ranked National Institutes of Health-funded orthopaedic surgery department, and accreditation achieved before 2017 to 2018 (P = 0.004). DISCUSSION: Most orthopaedic surgery residency programs do not have accessible parental leave policies on their websites. The new Accreditation Council for GME mandate will require orthopaedic residency programs to provide residents with 6 weeks of paid parental leave during residency training. Accessible policies may be useful to applicants interested in child rearing during orthopaedic residency training.

RESUMEN

OBJECTIVE: To examine the relationship between burnout and occupational fatigue exhaustion and recovery among orthopaedic nurses in Tabriz, Iran. DESIGN: Descriptive, cross-sectional survey and correlational analysis. SETTING: Two hospitals associated with Tabriz University of Medical Sciences, Iran, from August to September 2022. PARTICIPANTS: 92 bedside nurses in orthopaedic wards, each with >1 year of clinical experience. OUTCOME MEASURES: Burnout was assessed using the Copenhagen Burnout Inventory, and occupational fatigue exhaustion/recovery was measured with the Occupational Fatigue Exhaustion/Recovery Scale. Pearson's correlation, independent t-test, one-way analysis of variance and multivariable linear regression analyses determined statistical significance. RESULTS: The mean burnout score was 63.65 (±15.88) out of 100 and the recovery rate was 35.43 (±15.60) out of 100. There were significant correlations between total burnout and each of the exhaustion recovery dimensions: chronic fatigue (r=0.70), acute fatigue (r=0.65) and intershift recovery (r=0.56). Nurses exceeding 44 weekly work hours reported higher burnout (66.52±14.77, p=0.005) than those working fewer hours (56.25±16.12, p=0.005). Rotational shift status was associated with increased burnout (64.97±15.32) compared with fixed shifts (55.54±17.42, p=0.04). Chronic fatigue (B=0.39, 95% CI 0.21, 0.57; t=4.29, p<0.001) and intershift recovery (B=-0.241, 95% CI -0.46, -0.02; t=-2.16, p=0.035) were significant predictors of burnout. CONCLUSIONS: Burnout is a critical concern among orthopaedic nurses and is significantly linked to occupational fatigue/recovery. Addressing chronic fatigue and enhancing intershift energy recovery could mitigate burnout risk. Therefore, optimising work conditions and schedules and developing tailored recovery protocols are vital to safeguarding orthopaedic nurses' well-being.
