Inclusion of Sex and Gender in Emergency Medicine Research-A 2018 Update

Sex and gender-based analysis and diversity metric reporting in acute care trials published in high-impact journals: a systematic review

OBJECTIVE

To characterise sex and gender-based analysis (SGBA) and diversity metric reporting, representation of female/women participants in acute care trials and temporal changes in reporting before and after publication of the 2016 Sex and Gender Equity in Research guideline.

DESIGN

Systematic review.

DATA SOURCES

We searched MEDLINE for trials published in five leading medical journals in 2014, 2018 and 2020.

STUDY SELECTION

Trials that enrolled acutely ill adults, compared two or more interventions and reported at least one clinical outcome.

DATA ABSTRACTION AND SYNTHESIS

4 reviewers screened citations and 22 reviewers abstracted data, in duplicate. We compared reporting differences between intensive care unit (ICU) and cardiology trials.

RESULTS

We included 88 trials (75 (85.2%) ICU and 13 (14.8%) cardiology) (n=111 428; 38 140 (34.2%) females/women). Of 23 (26.1%) trials that reported an SGBA, most used a forest plot (22 (95.7%)), were prespecified (21 (91.3%)) and reported a sex-by-intervention interaction with a significance test (19 (82.6%)). Discordant sex and gender terminology were found between headings and subheadings within baseline characteristics tables (17/32 (53.1%)) and between baseline characteristics tables and SGBA (4/23 (17.4%)). Only 25 acute care trials (28.4%) reported race or ethnicity. Participants were predominantly white (78.8%) and male/men (65.8%). No trial reported gendered-social factors. SGBA reporting and female/women representation did not improve temporally. Compared with ICU trials, cardiology trials reported significantly more SGBA (15/75 (20%) vs 8/13 (61.5%) p=0.005).

CONCLUSIONS

Acute care trials in leading medical journals infrequently included SGBA, female/women and non-white trial participants, reported race or ethnicity and never reported gender-related factors. Substantial opportunity exists to improve SGBA and diversity metric reporting and recruitment of female/women participants in acute care trials.

Sex differences in febrile children with respiratory symptoms attending European emergency departments: An observational multicenter study

Objective

To assess sex differences in presentation and management of febrile children with respiratory symptoms attending European Emergency Departments.

Design and setting

An observational study in twelve Emergency Departments in eight European countries.

Patients

Previously healthy children aged 0–<18 years with fever (≥ 38°C) at the Emergency Department or in the consecutive three days before Emergency Department visit and respiratory symptoms were included.

Main outcome measures

The main outcomes were patient characteristics and management defined as diagnostic tests, treatment and admission. Descriptive statistics were used for patient characteristics and management stratified by sex. Multivariable logistic regression analyses were performed for the association between sex and management with adjustment for age, disease severity and Emergency Department. Additionally, subgroup analyses were performed in children with upper and lower respiratory tract infections and in children below five years.

Results

We included 19,781 febrile children with respiratory symptoms. The majority were boys (54%), aged 1–5 years (58%) and triaged as low urgent (67%). Girls presented less frequently with tachypnea (15% vs 16%, p = 0.002) and increased work of breathing (8% vs 12%, p<0.001) compared with boys. Girls received less inhalation medication than boys (aOR 0.82, 95% CI 0.74–0.90), but received antibiotic treatment more frequently than boys (aOR 1.09, 95% CI 1.02–1.15), which is associated with a higher prevalence of urinary tract infections. Amongst children with a lower respiratory tract infection and children below five years girls received less inhalation medication than boys (aOR 0.77, 95% CI 0.66–0.89; aOR 0.80, 95% CI 0.72–0.90).

Conclusions

Sex differences concerning presentation and management are present in previously healthy febrile children with respiratory symptoms presenting to the Emergency Department. Future research should focus on whether these differences are related to clinicians’ attitudes, differences in clinical symptoms at the time of presentation and disease severity.

Sex differences in clinical presentation and risk stratification in the Emergency Department: An observational multicenter cohort study

OBJECTIVE

The aim of this study was to investigate whether sex differences exist in disease presentations, disease severity and (case-mix adjusted) outcomes in the Emergency Department (ED).

METHODS

Observational multicenter cohort study using the Netherlands Emergency Department Evaluation Database (NEED), including patients ≥ 18 years of three Dutch EDs. Multivariable logistic regression was used to study the associations between sex and outcome measures in-hospital mortality and Intensive Care Unit/Medium Care Unit (ICU/MCU) admission in ED patients and in subgroups triage categories and presenting complaints.

RESULTS

Of 148,825 patients, 72,554 (48.8%) were females. Patient characteristics at ED presentation and diagnoses (such as pneumonia, cerebral infarction, and fractures) were comparable between sexes at ED presentation. In-hospital mortality was 2.2% in males and 1.7% in females. ICU/MCU admission was 4.7% in males and 3.1% in females. Males had higher unadjusted (OR 1.34(1.25-1.45)) and adjusted (AOR 1.34(1.24-1.46)) risks for mortality, and unadjusted (OR 1.54(1.46-1.63)) and adjusted (AOR 1.46(1.37-1.56)) risks for ICU/MCU admission. Males had higher adjusted mortality and ICU/MCU admission for all triage categories, and with almost all presenting complaints except for headache.

CONCLUSIONS

Although patient characteristics at ED presentation for both sexes are comparable, males are at higher unadjusted and adjusted risk for adverse outcomes. Males have higher risks in all triage categories and with almost all presenting complaints. Future studies should investigate reasons for higher risk in male ED patients.

Care of Sexual and Gender Minorities in the Emergency Department: A Scoping Review

STUDY OBJECTIVE

This scoping review was conducted to collate and summarize the published research literature addressing sexual and gender minority care in the emergency department (ED).

METHODS

Using PRISMA-ScR criteria, an electronic search was conducted of CINAHL, Embase, Ovid Medline, and Web of Science for all studies that were published after 1995 involving sexual and gender minorities, throughout all life stages, presenting to an ED. We excluded non-US and Canadian studies and editorials. Titles and abstracts were screened, and full-text review was performed independently with 4 reviewers. Abstraction focused on study design, demographics, and outcomes, and the resulting data were analyzed using an ad hoc iterative thematic analysis.

RESULTS

We found 972 unique articles and excluded 743 after title and abstract screening. The remaining 229 articles underwent full-text review, and 160 articles were included. Themes identified were HIV in sexual and gender minorities (n=61), population health (n=46), provider training (n=29), ED avoidance or barriers (n=23), ED use (n=21), and sexual orientation/gender identity information collection (n=9).

CONCLUSION

The current literature encompassing ED sexual and gender minority care cluster into 6 themes. There are considerable gaps to be addressed in optimizing culturally competent and equitable care in the ED for this population. Future research to address these gaps should include substantial patient stakeholder engagement in all aspects of the research process to ensure patient-focused outcomes congruent with sexual and gender minority values and preferences.

Sex bias persists in surgical research: A 5-year follow-up study

BACKGROUND

Federal initiatives have recently addressed the sex bias that exists in biomedical and clinical research. However, improvement to the inclusion of sex as a biological variable remains unknown.

METHODS

We performed a 5-year follow-up study of all clinical and biomedical research articles published in 5 surgical journals from January 1, 2017, through December 31, 2018. Human, animal, and cell subjects were analyzed for study/subject type, sex of participants, sex matching, and sex-based data reporting, analysis, and discussion.

RESULTS

Comparing 2017 to 2018 with 2011 to 2012, slightly more articles reported the sex of the human studied (87% vs 83%; P = .001). Inclusion of both sexes remained high (94% vs 95%; P = .22), but sex-based data reporting (36% vs 38%; P = .17), analysis (35% vs 33%; P = .39), and discussion of results (10% vs 23%; P < .0001) remained unchanged or worsened. Regarding animal research, the number of articles that stated the sex studied remained unchanged (79% vs 78%; P = .67); if stated, slightly more included both sexes (7% vs 3%; P = .002). Regarding cell research, fewer articles reported the sex of the cells studied (5% vs 24%; P = .0001); if stated, more articles included both sexes, but the difference did not reach statistical significance (25% vs 7%; P = .34). Sex matching remained poor with only 50% of human, 4% of animal, and 9% of cell studies matching the inclusion of both sexes by at least 50%.

CONCLUSION

Sex bias persists in surgical research. The majority of articles failed to report, analyze, or discuss results based on sex, which will negatively affect clinical translatability and outcomes of evidence-based medicine.

Emergency Physician Twitter Use in the COVID-19 Pandemic as a Potential Predictor of Impending Surge: Retrospective Observational Study

Background

The early conversations on social media by emergency physicians offer a window into the ongoing response to the COVID-19 pandemic.

Objective

This retrospective observational study of emergency physician Twitter use details how the health care crisis has influenced emergency physician discourse online and how this discourse may have use as a harbinger of ensuing surge.

Methods

Followers of the three main emergency physician professional organizations were identified using Twitter’s application programming interface. They and their followers were included in the study if they identified explicitly as US-based emergency physicians. Statuses, or tweets, were obtained between January 4, 2020, when the new disease was first reported, and December 14, 2020, when vaccination first began. Original tweets underwent sentiment analysis using the previously validated Valence Aware Dictionary and Sentiment Reasoner (VADER) tool as well as topic modeling using latent Dirichlet allocation unsupervised machine learning. Sentiment and topic trends were then correlated with daily change in new COVID-19 cases and inpatient bed utilization.

Results

A total of 3463 emergency physicians produced 334,747 unique English-language tweets during the study period. Out of 3463 participants, 910 (26.3%) stated that they were in training, and 466 of 902 (51.7%) participants who provided their gender identified as men. Overall tweet volume went from a pre-March 2020 mean of 481.9 (SD 72.7) daily tweets to a mean of 1065.5 (SD 257.3) daily tweets thereafter. Parameter and topic number tuning led to 20 tweet topics, with a topic coherence of 0.49. Except for a week in June and 4 days in November, discourse was dominated by the health care system (45,570/334,747, 13.6%). Discussion of pandemic response, epidemiology, and clinical care were jointly found to moderately correlate with COVID-19 hospital bed utilization (Pearson r=0.41), as was the occurrence of “covid,” “coronavirus,” or “pandemic” in tweet texts (r=0.47). Momentum in COVID-19 tweets, as demonstrated by a sustained crossing of 7- and 28-day moving averages, was found to have occurred on an average of 45.0 (SD 12.7) days before peak COVID-19 hospital bed utilization across the country and in the four most contributory states.

Conclusions

COVID-19 Twitter discussion among emergency physicians correlates with and may precede the rising of hospital burden. This study, therefore, begins to depict the extent to which the ongoing pandemic has affected the field of emergency medicine discourse online and suggests a potential avenue for understanding predictors of surge.

Filling the Regulatory Gap: Potential Role of Institutional Review Boards in Promoting Consideration of Sex as a Biological Variable

Consideration of sex differences in biomedical research is crucial to ensure the safety and effectiveness of drugs and devices for both sexes and to improve the rigor and reproducibility of scientific discoveries. Historically, women were underrepresented in clinical research and sex differences typically were not considered. The U.S. Food and Drug Administration (FDA) and the National Institutes of Health (NIH) have played a role in improving the representation of women in clinical trials and in encouraging the consideration of sex differences. As it is not appropriate for all studies to be reviewed by the FDA nor do all studies have NIH funding, this results in a regulatory gap. We propose that local institutional review boards (IRBs) and institutional animal care and use committees (IACUCs) provide greater oversight by encouraging researchers to consider sex as a biological variable (SABV) during protocol review. In this perspective article, we review how FDA and NIH policies have fostered change and highlight how IRBs and IACUCs could encourage investigators to consider SABV.

Integrating Sex and Gender into an Interprofessional Curriculum: Workshop Proceedings from the 2018 Sex and Gender Health Education Summit

Background: In the last 3 years, the National Institutes of Health (NIH) declared advancement of understanding the role sex as a biological variable has in research a priority. The burden now falls on educators and clinicians to translate into clinical practice the ensuing body of evidence for sex as a biological variable that clearly shows the effect of sex/gender on disease diagnosis and management. The 2018 Sex and Gender Health Education Summit (SGHE) organized an interdisciplinary and interprofessional workshop to (1) analyze common clinical scenarios highlighting the nuances of sex- and gender-based medicine (SGBM) in presentation, diagnosis, or management of illness; (2) utilize valid educational and assessment tools for a multiprofessional audience; and (3) brainstorm standardized learning objectives that integrate both. Materials and Methods: We describe the iterative process used to create these scenarios, as well as an interprofessional forum to develop standardized SGBM case-based objectives. Results: A total of 170 health education professionals representing 137 schools of Medicine, Dentistry, Pharmacy, Public Health, Nursing, Physical, and Occupational Therapy participated in this workshop. After attending the workshop, participants reported a significant increase in comfort level with using diverse educational modalities in the instruction of health profession learners. Recurrent themes included case-based learning, use of sex-neutral cases, simulation, and standardized patient scenarios for educational modalities; and self-assessment, peer assessment, and review of clinical documentation as used assessment tools. Materials created for the workshop included teaching SGBM case scenarios, methods of assessment, and sample standardized objectives. Conclusion: The SGHE Summit provided an interdisciplinary forum to create educational tools and materials for SABV instruction that may be applied to a diverse audience.
