Trend of female first authorship in Journal of Orthopaedic Science, the official journal of the Japanese orthopaedic association from 2001 to 2021: An observational study.

BACKGROUND: Women are underrepresented in orthopaedic surgery, especially in Japan. Authorship is associated with representation and career advancement, but the academic representation of women in Japanese orthopaedic surgery has not been elucidated. This study aimed to elucidate the proportion of female first authorship and its associating factors, as well as trends in the Journal of Orthopaedic Science (JOS), the official journal of the Japanese Orthopaedic Association. METHODS: The study reviewed original articles published in JOS from 2002 to 2021 using data from PubMed on March 16, 2022. The gender of the first and last authors was determined using genderize. io, an online gender detection tool and manual search. The study used multivariable logistic regression to identify the factors associated with female first authorship and visualized the trend of predicted probability using restricted cubic spline curve. RESULTS: Among 2272 original articles, 148 (6.5%) and 79 (3.5%) had female first and last authors, respectively. Compared with 2002-2006, female first authorship significantly increased in 2012-2016 (adjusted odds ratio [aOR], 2.04; 95% confidence interval [CI], 1.09-4.05; p = 0.03) and 2017-2021 (aOR, 2.72; 95% CI, 1.46-5.276; p = 0.002). Affiliation with an institution in Japan (aOR, 0.51; 95% CI, 0.35-0.74; p < 0.001) and affiliation in orthopaedics (aOR, 0.16; 95% CI, 0.11-0.23; p < 0.001) were negatively associated with female first authorship. Around 2020, the trend showed a gradual then rapid increase in women with non-orthopaedic affiliations. Only a very small increase was observed in women with an orthopaedic affiliation. CONCLUSIONS: Female first authorship in JOS has been increasing. However, the proportion of female authors remains low. Authors outside of Japan and not affiliated with orthopaedics largely affect female authorship statistics. The results indicate the persistent gender gap in the academic representation of women in Japanese orthopaedic publications.

Analysis of authorship trends in vascular surgery demonstrates a sticky surgical floor for women.

OBJECTIVE: Prior research in vascular surgery has identified significant gender disparities in leadership positions, but few data exist regarding gender disparities in vascular publications. This study aims to evaluate authorship trends by gender in the three highest impact factor vascular surgery journals. METHODS: In this bibliometric analysis, PubMed was searched for articles published in the European Journal of Vascular and Endovascular Surgery, the Journal of Vascular Surgery, and Annals of Vascular Surgery from 2015 to 2019. The web-based application Genderize used predictive algorithms to classify names of first and last authors as male or female. Statistical analyses regarding trends in authorship were performed using Stata16. RESULTS: A total of 6457 articles were analyzed, with first author gender predicted with >90% confidence in 83% (4889/5796) and last author gender in 88% (5078/5796). Overall, 25% (1223/4889) of articles had women first authors, and 10% (501/5078) had women last authors. From 2015 to 2019, there was a slight increase in the proportion of articles written by women first authors (P = .001), but no increase in the proportion of articles written by women last authors (P = .204). The proportion of articles written by women last authors was lower than the proportion of active women vascular surgeons in 2015 (8% of articles vs 11% of surgeons; P = .015), 2017 (9% of articles vs 13% of surgeons; P < .001), and 2019 (11% of articles vs 15% of practicing surgeons; P < .001). The average number of last-author publications was higher for men (2.35 ± 3.76) than for women (1.62 ± 1.88, P = .001). The proportion of unique authors who were women was less than the proportion of active women vascular surgeons in 2017 (10% unique authors vs 13% surgeons; P = .047), but not in 2015 (9% unique authors vs 11% surgeons; P = .192) or 2019 (13% unique authors vs 15% surgeons; P = .345). Notably, a woman last author was associated with 1.45 higher odds of having a woman first author (95% confidence interval, 1.17-1.79; P = .001). CONCLUSIONS: Over the past 5 years, there has been no significant increase in women last authors among top-tier journals in vascular surgery. Women remain under-represented as last authors in terms of proportion of published articles, but not in terms of proportion of unique authors. Nevertheless, women last authors are more likely to publish with women first authors, indicating the importance of women-led mentorship in achieving publication gender equity. Support for women surgeons through grants and promotions is essential not only for advancing last authorship gender equity, but for advancing junior faculty and trainee academic careers.

Factors Influencing Hospital Readmission after Lower Extremity Bypass for Chronic Limb-Threatening Ischemia.

Objectives: Unplanned hospital readmission is a leading source of hospital resource expenditure, and preventing readmission may improve both patient quality of life and healthcare costs. The factors influencing hospital readmission after lower extremity bypass (LEB) for chronic limb-threatening ischemia (CLTI) remain incompletely investigated. Methods: A regional, multi-institutional database was retrospectively reviewed for all patients who underwent LEB for CLTI between 1995 to 2020. The primary outcome was unplanned hospital readmission up to 30 days following bypass. Results: A total of 1315 patients underwent LEB across all institutions, of whom 843 (64.1%) underwent bypass for CLTI. The 30-day hospital readmission rate was 25.3%, and the leading causes of readmission were wound-related complications (51.6%). There was no difference in age, sex, or race between readmitted and non-readmitted patients. Conduit type and bypass target were also similar between groups. Readmitted patients more frequently underwent LEB for tissue loss (58.2% vs 50.2%, P = 0.042). On multivariable analysis, wound infection (odds ratio [OR] 9.1, 95% confidence interval [CI] 6.2-13.2, P < 0.001) and non-infectious wound complications (OR 2.0, 95% CI 1.0-3.9, P = 0.041) were independently associated with hospital readmission. Factors not associated with hospital readmission included patient age, conduit type, distal bypass target, and other medical comorbidities. Conclusions: One quarter of patients are readmitted within 30 days following lower extremity bypass for chronic limb-threatening ischemia. Efforts to mitigate wound infection and non-infectious wound complications may decrease rates of unplanned hospital readmission.

What to scale first? A cross-sectional analysis of factors affecting cesarean delivery rates at first referral units in Bihar, India.

BACKGROUND: Low rates of caesarean delivery (CD) (<10%) hinder access to a lifesaving procedure for the most vulnerable populations in low-resource settings, but there is a paucity of data regarding which factors contribute most to CD rates. OBJECTIVES: We aimed to determine caesarean delivery rates at Bihar's first referral units (FRUs) stratified by facility level (regional, sub-district, district). The secondary aim was to identify facility-level factors associated with caesarean delivery rates. METHODS: This cross-sectional study used open-source national datasets from government FRUs in Bihar, India, from April 2018-March 2019. Multivariate Poisson regression analysed association of infrastructure and workforce factors with CD rates. RESULTS: Of 546,444 deliveries conducted at 149 FRUs, 16961 were CDs, yielding a state-wide FRU CD of 3.1%. There were 67 (45%) regional hospitals, 45 (30%) sub-district hospitals, and 37 (25%) district hospitals. Sixty-one percent of FRUs qualified as having intact infrastructure, 84% had a functioning operating room, but only 7% were LaQshya (Labour Room Quality Improvement Initiative) certified. Considering workforce, 58% had an obstetrician-gynaecologist (range 0-10), 39% had an anaesthetist (range 0-5), and 35% had a provider trained in Emergency Obstetric Care (EmOC) (range 0-4) through a task-sharing initiative. The majority of regional hospitals lack the essential workforce and infrastructure to perform CDs. Multivariate regression including all FRUs performing deliveries demonstrated that presence of a functioning operating room (IRR = 21.0, 95%CI 7.9-55.8, p < 0.001) and the number of obstetrician-gynaecologists (IRR = 1.3, 95%CI 1.1-1.4, p = 0.001) and EmOCs (IRR = 1.6, 95%CI 1.3-1.9, p < 0.001) were associated with facility-level CD rates. CONCLUSION: Only 3.1% of the institutional childbirths in Bihar's FRUs were by CD. The presence of a functional operating room, obstetrician, and task-sharing provider (EmOC) was strongly associated with CD. These factors may represent initial investment priorities for scaling up CD rates in Bihar.

The current status of the diversity pipeline in surgical training.

OBJECTIVE: Recent initiatives have emphasized the importance of diversity, equity, and inclusion in academic surgery. Racial/ethnic disparities remain prevalent throughout surgical training, and the "diversity pipeline" in resident recruitment and retention remains poorly defined. METHODS: Data was retrospectively collected using two separate datasets. The Association of American Medical Colleges database was used to obtain demographic data on US medical school graduates. The US Graduate Medical Education annual report was used to obtain demographic data on surgical residents. Wilcoxon signed-rank test was used to compare racial/ethnic distribution within surgical residency programs with graduating medical students. Linear regression analysis was performed to analyze population trends over time. RESULTS: The study population included 184,690 surgical residents from 2011 to 2020. Nine resident cohorts were created according to surgical specialty - general surgery, neurosurgery, ophthalmology, orthopedic surgery, otolaryngology, plastic surgery, cardiothoracic surgery, urology, and vascular surgery. Among surgical programs, White residents were overrepresented in 8 of 9 specialties compared to the concurrent graduating medical student class for all years (p < 0.01 each, no difference in ophthalmology). Black residents were underrepresented in 8 of 9 specialties (p < 0.01 each, no difference in general surgery). Asian representation was mixed among specialties (4 overrepresented, 1 equal, 4 underrepresented), as was Hispanic representation (5 overrepresented, 4 equal) (p < 0.01 each). CONCLUSIONS: These data suggest that racial/ethnic disparities are inherent to the process of recruitment and retention of surgical residents. Efforts to improve the "diversity pipeline" should focus on mentorship and development of minority medical students and creating an equitable learning environment.

A cohort study of differences in trauma outcomes between females and males at four Indian Urban Trauma Centers.

Background Studies from high income countries suggest improved survival for females as compared to males following trauma. However, data regarding differences in trauma outcomes between females and males is severely lacking from low- and middle-income countries. The objective of this study was to determine the association between sex and clinical outcomes amongst Indian trauma patients using the Australia-India Trauma Systems Collaboration database. Methods A prospective multicentre cohort study was performed across four urban public hospitals in India April 2016 through February 2018. Bivariate analyses compared admission physiological parameters and mechanism of injury. Logistic regression assessed association of sex with the primary outcomes of 30-day and 24-hour in-hospital mortality. Secondary outcomes included ICU admission, ICU length of stay, ventilator requirement, and time on a ventilator. Results Of 8,605 patients, 1,574 (18.3%) were females. The most common mechanism of injury was falls for females (52.0%) and road traffic injury for males (49.5%). On unadjusted analysis, there was no difference in 30-day in-hospital mortality between females (11.6%) and males (12.6%, p = 0.323). However, females demonstrated a lower mortality at 24-hours (1.1% vs males 2.1%, p = 0.011) on unadjusted analysis. Females were also less likely to require a ventilator (17.3% vs 21.0% males, p = 0.001) or ICU admission (34.4% vs 37.5%, p = 0.028). Stratification by age or by ISS demonstrated no difference in 30-day in-hospital mortality for males vs females across age and ISS categories. On multivariable regression analysis, sex was not associated significantly with 30-day or 24-hour in-hospital mortality. Conclusion This study did not demonstrate a significant difference in the 30-day trauma mortality or 24-hour trauma mortality between female and male trauma patients in India on adjusted analyses. A more granular data is needed to understand the interplay of injury severity, immediate post-traumatic hormonal and immunological alterations, and the impact of gender-based disparities in acute care settings.

The Changing Demographics of Surgical Trainees in General and Vascular Surgery: National Trends over the Past Decade.

OBJECTIVE: Recent initiatives have targeted the issue of gender and ethnic/racial disparities in general surgery and vascular surgery. However, the prevalence of these disparities in general and vascular surgical training programs is unknown. DESIGN: A retrospective analysis was conducted using data from three separate sources, including the US Graduate Medical Education annual report, Electronic Residency Application Service database, and National Resident Matching Program annual report. Demographic information regarding gender distribution and ethnic/racial identity was collected from 328 general surgery residency programs, 59 vascular surgery residency programs, and 100 vascular surgery fellowship programs across the US. The primary outcomes of this study were to evaluate national trends in gender and ethnic diversity in general surgery and vascular surgery training programs, including both traditional fellowship and integrated residency paradigms. RESULTS: From 2011-2020, general surgery residency programs showed a positive trend towards both female applicants (from 31.9%-41.5%) and trainees (from 36.2%-43.1%) (p < 0.0001 each). The proportion of minority trainees decreased, primarily among Black (from 7.2%-5.4%) and Asian trainees (from 21.5%-19.2%) (p < 0.0001 each). Concurrently, the number of vascular integrated residency programs grew from 27 to 59, resulting in a fivefold increase in trainees (from 64-335). Despite this growth, there was no change in the proportion of women applicants or trainees for both vascular integrated residency (24.9% applicants; 36.2% trainees) and fellowship programs (27.4% applicants; 25.9% trainees) over the study period (p = 0.11, 0.89, 0.43, and 0.13 respectively). Moreover, there was no significant change in proportion of minority trainees in both vascular integrated residency and fellowship programs. CONCLUSION: While general surgery programs have expanded in proportion of both female applicants and trainees, racial diversity has decreased. Gender and racial diversity in vascular training has not changed. Future initiatives in general and vascular surgery should focus on recruitment and promotion of proficient women and minority trainees.

A multi-institutional study of patient-derived gender-based discrimination experienced by resident physicians.

BACKGROUND: This study characterizes prevalence, frequency, and forms of patient-derived gender-based discrimination (GBD) experienced by resident physicians, as well as their experiences witnessing and reporting patient-derived GBD. METHODS: A web-based survey was sent to residents from 12 programs at three academic institutions. RESULTS: Response rate was 47.9% (309/645) with 55.0% of respondents identifying as women. Women were more likely than men to experience patient-derived GBD during residency (100% vs 68.8%, p < 0.001), including inappropriate physical contact, receiving less trust from patients, and being mistaken for a nurse (p < 0.001). While 85.9% of residents personally experienced and 95.0% of residents witnessed patient-derived GBD, only 3.4% of residents formally reported patient-derived GBD. Women were more likely to report negative personal and professional consequences of patient-derived GBD. CONCLUSIONS: Patient-derived GBD is pervasive and disproportionately affects women residents. Current reporting mechanisms are not adequately capturing nor addressing patient-derived GBD.

A qualitative assessment of the impact of a uterine balloon tamponade package on decisions regarding the role of emergency hysterectomy in women with uncontrolled postpartum haemorrhage in Kenya and Senegal.

OBJECTIVES: To assess the impact of a every second matters for mothers and babies uterine balloon tamponade package (ESM-UBT) on provider decisions regarding emergency hysterectomy in cases of uncontrolled postpartum haemorrhage (PPH). DESIGN: Qualitative assessment and analysis of a subgroup extracted from a larger database that contains all UBT device uses among ESM-UBT trained health providers. SETTING: Health facilities in Kenya and Senegal with ESM-UBT training and capable of performing emergency hysterectomies. PARTICIPANTS: All medical doctors who had placed a UBT for uncontrolled PPH subsequent to implementation of ESM-UBT at their facility, and who also had the capabilities of performing emergency hysterectomies. PRIMARY OUTCOME MEASURES: The impact of ESM-UBT on decisions regarding emergency hysterectomy in cases of uncontrolled PPH. RESULTS: 30 of the 31 medical doctors (97%) who fulfilled the inclusion criteria were independently interviewed. Collectively the interviewed medical doctors had placed over 80 UBT devices for uncontrolled PPH since ESM-UBT implementation. All 30 responded that UBT devices immediately controlled haemorrhage and prevented women from being taken to emergency hysterectomy. All 30 would continue to use UBT devices in future cases of uncontrolled PPH. CONCLUSIONS: These preliminary data suggest that following ESM-UBT implementation, emergency hysterectomy for uncontrolled PPH may be averted by use of uterine balloon tamponade.
