The Importance of Perceived Barriers to Women Entering and Advancing in Orthopaedic Surgery in the US and Beyond.

BACKGROUND: Global perceptions of barriers to women in orthopaedics have not been assessed. The purpose of this study was to determine the importance of international barriers to women entering and advancing within orthopaedic surgery. METHODS: An anonymous, online survey was distributed to women medical students, trainees, and practicing surgeons via Women in Orthopaedics Worldwide, the "Women in Ortho" Facebook page, and individual programmes. Participants were asked to rate perceived barriers to (1) pursuing training and (2) career advancement on a scale of 1-5, with 5 being the most important and relative to other barriers. Descriptive statistics and univariate analyses were employed. RESULTS: The survey yielded 237 US (84.0%) and 45 international (16.0%) respondents. Per entering orthopaedic surgery, the most important barriers were male-dominated culture, lack of a strong women mentor, and lack of female representation at home institution. Compared with the US surgeons/trainees, international respondents cited greater societal disapproval (2.8 ± 1.2 vs. 3.4 ± 1.3, P = 0.01). Medical students assigned less importance to lack of exposure, more to lack of resources for creating competitive applications (P < 0.05). Regarding career advancement, lack of women leadership, family responsibilities, and gender-biased selection for promotion were the most important. International surgeons/trainees noted greater concern for societal disapproval (3.5 ± 1.5 vs. 2.6 ± 1.3, P = 0.003) and were more likely to rank sexual harassment in their top three (17.6 vs. 4.2%, P = 0.02). CONCLUSION: While notable differences exist, there is striking similarity across countries and position levels in perceived barriers to women entering and advancing in orthopaedic surgery.

Wearable sensor and machine learning accurately estimate tendon load and walking speed during immobilizing boot ambulation.

Achilles tendon injuries are treated with progressive weight bearing to promote tendon healing and restore function. Patient rehabilitation progression are typically studied in controlled, lab settings and do not represent the long-term loading experienced during daily living. The purpose of this study is to develop a wearable paradigm to accurately monitor Achilles tendon loading and walking speed using low-cost sensors that reduce subject burden. Ten healthy adults walked in an immobilizing boot under various heel wedge conditions (30°, 5°, 0°) and walking speeds. Three-dimensional motion capture, ground reaction force, and 6-axis inertial measurement unit (IMU) signals were collected per trial. We used Least Absolute Shrinkage and Selection Operator (LASSO) regression to predict peak Achilles tendon load and walking speed. The effects of using only accelerometer data, different sampling frequency, and multiple sensors to train the model were also explored. Walking speed models outperformed (mean absolute percentage error (MAPE): 8.41 ± 4.08%) tendon load models (MAPE: 33.93 ± 23.9%). Models trained with subject-specific data performed significantly better than generalized models. For example, our personalized model that was trained with only subject-specific data predicted tendon load with a 11.5 ± 4.41% MAPE and walking speed with a 4.50 ± 0.91% MAPE. Removing gyroscope channels, decreasing sampling frequency, and using combinations of sensors had inconsequential effects on models performance (changes in MAPE < 6.09%). We developed a simple monitoring paradigm that uses LASSO regression and wearable sensors to accurately predict Achilles tendon loading and walking speed while ambulating in an immobilizing boot. This paradigm provides a clinically implementable strategy to longitudinally monitor patient loading and activity while recovering from Achilles tendon injuries.

Does Time to Imaging and Surgery for Distal Radius Fractures Vary based on Geographic Socioeconomic Disadvantage?

BACKGROUND: While disparities in aspects of distal radius fracture (DRF) management and orthopedics at large have been studied, disparities in time to DRF evaluation and treatment are unknown. We sought to determine if geographic socioeconomic disadvantage is associated with time to imaging in the emergency department (ED) and time to surgery for DRFs. METHODS: We performed a time-to-event analysis of 105 patients undergoing DRF surgery after ED triage within our hospital system between January 1, 2015, and January 1, 2020. Area Deprivation Index (ADI) national percentile was used as the metric of geographic socioeconomic disadvantage for each patient's ZIP code of residence. We performed Cox regression analysis to determine hazard ratios to undergo DRF imaging and surgery for patients in each ADI group, adjusting for potential confounders, α = 0.05. RESULTS: There was no association between geographic socioeconomic disadvantage and time to DRF imaging, after adjusting for confounders. However, compared to patients from the least disadvantaged areas, patients from the most disadvantaged areas (ADI Quartiles 3 and 4) had an adjusted hazard ratio for surgery of 0.55 [0.32, 0.94] (P = .03), and were thus 45% [6%, 68%] less likely to undergo surgery for DRF at any time following ED triage. CONCLUSIONS: Operative patients from more socioeconomically disadvantaged neighborhoods see disparities in time to surgery for DRF. Equitable access to timely surgical care is needed and may be improved with increased access to orthopedic surgeons, patient education, support in navigating the health system, and improved continuity of fracture care. LEVEL OF EVIDENCE: Level III.

Patient understanding regarding opioid use in an orthopaedic trauma surgery population: a survey study.

BACKGROUND: Prior studies have assessed provider knowledge and factors associated with opioid misuse; similar studies evaluating patient knowledge are lacking. The purpose of this study was to assess the degree of understanding regarding opioid use in orthopaedic trauma patients. We also sought to determine the demographic factors and clinical and personal experiences associated with level of understanding. METHODS: One hundred and sixty-six adult orthopaedic trauma surgery patients across two clinical sites of an academic institution participated in an internet-based survey (2352 invited, 7.1% response rate). Demographic, clinical, and personal experience variables, as well as perceptions surrounding opioid use were collected. Relationships between patient characteristics and opioid perceptions were identified using univariate and multivariable logistic regressions. Alpha = 0.05. RESULTS: Excellent recognition (> 85% correct) of common opioids, side effects, withdrawal symptoms, and disposal methods was demonstrated by 29%, 10%, 30%, and 2.4% of patients; poor recognition (< 55%) by 11%, 56%, 33%, and 52% of patients, respectively. Compared with white patients, non-white patients had 7.8 times greater odds (95% confidence interval [CI] 1.9-31) of perceiving addiction discrepancy (p = 0.004). Employed patients with higher education levels were less likely to have excellent understanding of side effects (adjusted odds ratio [aOR] 0.06, 95% CI 0.006-0.56; p = 0.01) and to understand that dependence can occur within 2 weeks (aOR 0.28, 95% CI 0.09-0.86; p = 0.03) than unemployed patients. Patients in the second least disadvantaged ADI quartile were more knowledgeable about side effects (aOR 8.8, 95% CI 1.7-46) and withdrawal symptoms (aOR 2.7, 95% CI 1.0-7.2; p = 0.046) than those in the least disadvantaged quartile. Patients who knew someone who was dependent or overdosed on opioids were less likely to perceive addiction discrepancy (aOR 0.24, 95% CI 0.07-0.76; p = 0.02) as well as more likely to have excellent knowledge of withdrawal symptoms (aOR 2.6, 95% CI 1.1-6.5, p = 0.03) and to understand that dependence can develop within 2 weeks (aOR 3.8, 95% CI 1.5-9.8, p = 0.005). CONCLUSIONS: Level of understanding regarding opioid use is low among orthopaedic trauma surgery patients. Clinical and personal experiences with opioids, in addition to demographics, should be emphasized in the clinical history.

Septic Arthritis Among Users of Injection Drugs: Clinical Course and Microbial Characteristics.

Injection drug use (IDU) is a risk factor for septic arthritis (SA) of native joints. Amid the opioid crisis, IDU rates have increased. This study assessed differences in pre-operative characteristics, microbial characteristics, and postoperative outcomes of 177 cases of SA treated operatively from 2015 to 2019 at 3 US hospitals, by self-reported IDU status. Forty cases (23%) involved patients who reported IDU. Patient characteristics, comorbidities, microbial characteristics, duration of hospital stay, discharge destination, follow-up rates, and rates of persistent/secondary infection were compared by self-reported IDU status. Compared with non-IDU-associated SA (non-IDU-SA), IDU-associated SA (IDU-SA) was associated with female sex (P=.001), younger age (P<.001), lower body mass index (P<.001), tobacco use (P<.001), and psychiatric diagnosis (P=.04) and was more likely to involve methicillin-resistant Staphylococcus aureus (P<.001). The IDU-SA was associated with discharge to a skilled nursing facility or against medical advice (P<.001) and with loss to follow-up (P=.01). The 2 groups did not differ in terms of American Society of Anesthesiologists classification, joint involved, Gram stain positivity, presence of bacteremia, peripherally inserted central catheter placement, return to hospital within 3 months, or persistent/secondary positive results on culture within 3 months. Patients with IDU-SA were younger, were more likely to be female, had lower body mass index, and had fewer medical comorbidities but were more likely to use tobacco and to have a psychiatric diagnosis compared with patients with non-IDU-SA. Methicillin-resistant S aureus was more common in the IDU-SA group, as was discharge to a skilled nursing facility or against medical advice. Patients with IDU-SA were less likely to return for follow-up than patients with non-IDU-SA. [Orthopedics. 2021;44(6):e747-e752.].

Is Geographic Socioeconomic Disadvantage Associated with the Rate of THA in Medicare-aged Patients?

BACKGROUND: Disparities in THA use may lead to inequitable care. Prior research has focused on disparities based on individual-level and isolated socioeconomic and demographic variables. To our knowledge, the role of composite, community-level geographic socioeconomic disadvantage has not been studied in the United States. As disparities persist, exploring the potential underlying drivers of these inequities may help in developing more targeted recommendations on how to achieve equitable THA use. QUESTIONS/PURPOSES: (1) Is geographic socioeconomic disadvantage associated with decreased THA rates in Medicare-aged patients? (2) Do these associations persist after adjusting for differences in gender, race, ethnicity, and proximity to hospitals performing THA? METHODS: In a study with a cross-sectional design, using population-based data from five-digit ZIP codes in Maryland, USA, from July 1, 2012 to March 31, 2019, we included all inpatient and outpatient primary THAs performed in individuals 65 years of age or older at acute-care hospitals in Maryland, as reported in the Health Services Cost Review Commission database. This database was selected because it provided the five-digit ZIP code data necessary to answer our study question. We excluded THAs performed for nonelective indications. We examined the annual rate of THA in our study population for each Maryland ZIP code, adjusted for differences across areas in distributions of gender, race, ethnicity, and distance to the nearest hospital performing THAs. Four hundred fourteen ZIP codes were included, with an overall mean ± SD THA rate of 371 ± 243 per 100,000 persons 65 years or older, a rate similar to that previously reported in individuals aged 65 to 84 in the United States. Statistical significance was assessed at α = 0.05. RESULTS: THA rates were higher in more affluent areas, with the following mean rates per 100,000 persons 65 years or older: 422 ± 259 in the least socioeconomically disadvantaged quartile, 339 ± 223 in the second-least disadvantaged, 277 ± 179 in the second-most disadvantaged, and 214 ± 179 in the most-disadvantaged quartile (p < 0.001). After adjustment for distributions in gender, race, ethnicity, and hospital proximity, we found that geographic socioeconomic disadvantage was still associated with THA rate. Compared with the least-disadvantaged quartile, the second-least disadvantaged quartile had 63 fewer THAs per 100,000 people (95% confidence interval 12 to 114), the second-most disadvantaged quartile had 136 fewer THAs (95% CI 62 to 211), and the most-disadvantaged quartile had 183 fewer THAs (95% CI 41 to 325). CONCLUSION: Geographic socioeconomic disadvantage may be the underlying driver of disparities in THA use. Although our study does not determine the "correct" rate of THA, our findings support increasing access to elective orthopaedic surgery in disadvantaged geographic communities, compared with prior research and efforts that have studied and intervened on the basis of isolated factors such as race and gender. Increasing access to orthopaedic surgeons in disadvantaged neighborhoods, educating physicians about when surgical referral is appropriate, and educating patients from these geographic communities about the risks and benefits of THA may improve equitable orthopaedic care across neighborhoods. Future studies should explore disparities in rates of appropriate THA and the role of density of orthopaedic surgeons in an area. LEVEL OF EVIDENCE: Level III, therapeutic study.

A Bioethical Perspective for Navigating Moral Dilemmas Amidst the COVID-19 Pandemic.

The Coronavirus disease 2019 pandemic has been an unprecedented challenge to healthcare systems and clinicians around the globe. As the virus has spread, critical questions arose about how to best deliver health care in emergency situations where material and personnel resources become scarce. Clinicians who excel at caring for the individual patient at the bedside are now being reoriented into a system where they are being asked to see the collective public as their responsibility. As such, the clinical ethics that clinicians are accustomed to practicing are being modified by a framework of public health ethics defined by the presence of a global pandemic. There are many unknowns about Coronavirus disease 2019, which makes it difficult to provide consistent recommendations and guidelines that uniformly apply to all situations. This lack of consensus leads to the clinicians' confusion and distress. Real-life dilemmas about how to allocate resources and provide care in hotspot cities make explicit the need for careful ethical analysis, but the need runs far deeper than that; even when not trading some lives against others, the responsibilities of both individual clinicians and the broader healthcare system are changing in the face of this crisis.

What Should an Anesthesiologist and Surgeon Do When They Disagree About Terms of Perioperative DNR Suspension?

This case examines perioperative suspension of a do-not-resuscitate (DNR) order during surgery. The commentary considers the appropriateness of DNR orders; types of DNR order suspension in the context of alternative anesthesia techniques; and what is required from a surgeon, anesthesiologist, and patient or surrogate to reach a decision expressing the patient's best interest. It concludes by offering communication recommendations based on joint discussion and decision sharing.

Reconstruction of ulnar defect with vascularized rib graft: A case report.

This case report describes the reconstruction of a segmental ulnar defect using a vascularized rib graft. A 27-year-old man was injured during military service by an improvised explosive device, resulting in bilateral through-the-knee amputations, left hand deformity, and a segmental left ulnar defect. After unsuccessful ulnar reconstruction with nonvascularized autologous bone and allograft bone substitutes, he presented to our institution. We removed the residual allograft fragments from the ulnar defect, harvested a vascularized left sixth rib with the intercostal artery and vein, secured the construct with internal hardware, and performed microanastomoses of the intercostal artery and vein to the posterior interosseous artery and vein. Postoperatively, he had a hematoma at the vascularized graft recipient site caused by anticoagulation therapy for his chronic deep vein thrombosis. Despite this, the rib graft successfully incorporated on the basis of radiographic and clinical examinations at 27 months. He had no pain and good function of the arm. The results of this case suggest that a vascularized rib graft for forearm reconstruction may be a viable option with minimal donor site morbidity. © 2015 Wiley Periodicals, Inc.
