Variation in Sexual Orientation Documentation in a National Electronic Health Record System

Sexual and Gender Minority Status and Suicide Mortality: An Explainable Artificial Intelligence Analysis

Objectives: Suicide risk is elevated in lesbian, gay, bisexual, and transgender (LGBT) individuals. Limited data on LGBT status in healthcare systems hinder our understanding of this risk. This study used natural language processing to extract LGBT status and a deep neural network (DNN) to examine suicidal death risk factors among US Veterans. Methods: Data on 8.8 million veterans with visits between 2010 and 2017 was used. A case-control study was performed, and suicide death risk was analyzed by a DNN. Feature impacts and interactions on the outcome were evaluated. Results: The crude suicide mortality rate was higher in LGBT patients. However, after adjusting for over 200 risk and protective factors, known LGBT status was associated with reduced risk compared to LGBT-Unknown status. Among LGBT patients, black, female, married, and older Veterans have a higher risk, while Veterans of various religions have a lower risk. Conclusion: Our results suggest that disclosed LGBT status is not directly associated with an increase suicide death risk, however, other factors (e.g., depression and anxiety caused by stigma) are associated with suicide death risks.

Differences by Sexual Orientation in Patient-Centered Care Outcomes for Veterans Utilizing Primary Care Services at the Veterans Health Administration

Purpose: This study examined the differences by sexual orientation in patient-centered care outcomes (including health care experiences and health-related screening) of veterans utilizing Veterans Health Administration (VHA) primary care. Methods: VHA's adapted version of the Consumer Assessment of Healthcare Providers and Systems was used to compare the health care experience of primary care services among sexual minority (SM) and heterosexual veterans. Health care experience measures were dichotomized to "always" versus "less" and stratified by SM status. Health-related screening measures were dichotomous. Survey data were weighted using provided sample weights. Descriptive statistics were performed on sociodemographic characteristics. Logistic regression coefficients were represented as adjusted odds ratios (aORs). A total of 66,348 veterans were included in the analytic sample, of which 2.9% (n = 1,935) identified as SM. Sexual orientation was ascertained by self-report measures by veterans. Results: SM veterans were significantly younger (56.95 years vs. 63.43 years, p < 0.001), were less likely to report that their provider showed respect for what they had to say (aOR: 0.76; 95% confidence interval [CI]: 0.61-0.95), that they were asked about difficulties taking care of their health (aOR: 0.81; 95% CI: 0.67-0.96), and their provider listened carefully to them (aOR: 0.71; 95% CI: 0.57-0.87) compared to heterosexual veterans. Conclusion: Health care experiences differed between SM and heterosexual veterans who sought VHA primary care, suggesting the need to increase provider trainings, which may improve cultural competency and promote a more welcoming and inclusive environment.

HIV Testing and Preexposure Prophylaxis Prescriptions Among U.S. Commercially Insured Transgender Men and Women, 2014 to 2021

BACKGROUND

Transgender persons are disproportionately affected by HIV, but preexposure prophylaxis (PrEP) use has been low in this population. Clinical encounters for gender-affirming hormone therapy (GAHT) provide opportunities for HIV prevention.

OBJECTIVE

To estimate the number of commercially insured transgender women (TGW) and transgender men (TGM) in the United States and their use of HIV prevention services.

DESIGN

Retrospective analysis of secondary data.

SETTING

Merative MarketScan commercial databases from 2014 to 2021.

PARTICIPANTS

TGW and TGM, defined as those with transgender-related diagnoses and prescriptions for feminizing or masculinizing GAHT.

MEASUREMENTS

HIV testing and PrEP use.

RESULTS

A substantially increasing trend was observed in the prevalence of transgender-related diagnosis codes from 2014 to 2021 and in the proportion of persons who used GAHT. The increases were driven by persons aged 18 to 34 years. In 2021, among 10 613 TGW with a test for or a diagnosis of a sexually transmitted infection (STI) in the previous 12 months, 61.1% had an HIV test; among those, 20.2% were prescribed PrEP. Among 4184 TGM with STI risk, 48.3% had an HIV test; among those, 10.2% were prescribed PrEP. The prevalence of TGW and TGM who had a test for or a diagnosis of an STI, had an HIV test, and were prescribed PrEP increased substantially from 2014 to 2021.

LIMITATION

The findings represent only persons with commercial health insurance who sought health care services for GAHT.

CONCLUSION

It is important to identify transgender persons to monitor their receipt of HIV prevention services. Encounters for GAHT provide opportunities to offer HIV prevention and other prevention services. Many HIV prevention opportunities were likely missed at clinical encounters for GAHT.

Probable PTSD, PTSD symptom severity, and comorbid PTSD and hazardous drinking among sexual minority women compared to heterosexual women: A meta-analysis

Posttraumatic stress disorder (PTSD) is more prevalent among sexual minority women (SMW) than among heterosexual women. PTSD risk varies among SMW, but no meta-analysis has clarified sexual identity-related disparities in probable PTSD among women or SMW's heterogeneity in PTSD risk. SMW are also at pronounced risk of comorbid PTSD and hazardous drinking (HD). However, the difference in comorbid PTSD/HD between SMW and heterosexual women is understudied. This meta-analysis aimed to provide a comprehensive understanding of differences between SMW and heterosexual women and among SMW across demographic characteristics. Peer-reviewed publications that were written in English and reported quantitative data on PTSD specific to SMW were included. Eligible publications (n = 45) were identified through a systematic search of 11 electronic databases, supplemented by a search of reference lists of relevant papers. We found that probable PTSD, PTSD symptom severity, and probable comorbid PTSD/HD are highly prevalent among SMW, with SMW of color, transgender and gender diverse people, and bi+ women (e.g., bisexual, pansexual, queer) being at greatest risk. These results emphasize the need to improve accurate assessment of trauma-related sequelae among SMW and to develop, disseminate, and implement culturally sensitive treatments to reduce PTSD and comorbid PTSD/HD among at-risk SMW.

Primary sources of health care among LGBTQ+ veterans: Findings from the Behavioral Risk Factor Surveillance System

OBJECTIVE

This study examined the primary source of health care between veterans with lesbian, gay, bisexual, queer and similar identities (LGBTQ+) and non-LGBTQ+ veterans.

DATA SOURCES AND STUDY SETTING

Veterans (N = 20,497) from 17 states who completed the CDC's Behavioral Risk Factor Surveillance System from 2016 to 2020, including the Sexual Orientation and Gender Identity and Health Care Access modules.

STUDY DESIGN

We used survey-weighted multiple logistic regression to estimate average marginal effects of the prevalence of utilization of Veteran's Health Administration (VHA)/military health care reported between LGBTQ+ and non-LGBTQ+ veterans. Prevalence estimates were adjusted for age group, sex, race and ethnicity, marital status, educational attainment, employment status, survey year, and US state.

DATA COLLECTION METHODS

Study data were gathered via computer-assisted telephone interviews with probability-based samples of adults aged 18 and over. Data are publicly available.

PRINCIPAL FINDINGS

Overall, there was not a statistically significant difference in estimated adjusted prevalence of primary use of VHA/military health care between LGBTQ+ and non-LGBTQ+ veterans (20% vs. 23%, respectively, p = 0.13). When examined by age group, LGBTQ+ veterans aged 34 and younger were significantly less likely to report primary use of VHA/military health care compared to non-LGBTQ+ veterans (25% vs. 44%, respectively; p = 0.009). Similarly, in sex-stratified analyses, fewer female LGBTQ+ veterans than female non-LGBTQ+ veterans reported VHA/military health care as their primary source of care (13% vs. 29%, respectively, p = 0.003). Implications and limitations to these findings are discussed.

CONCLUSIONS

Female and younger LGBTQ+ veterans appear far less likely to use VHA/military for health care compared to their cisgender, heterosexual peers; however, because of small sample sizes, estimates may be imprecise. Future research should corroborate these findings and identify potential reasons for these disparities.

Social Stressors and Health Among Older Transgender and Gender Diverse Veterans

Purpose: Health disparities in transgender and gender diverse (TGD) veterans compared with cisgender veterans have been documented. However, there is a paucity of literature focused on older TGD veterans. We assessed health conditions and social stressors in older TGD veterans compared with matched cisgender veterans. Methods: Using gender identity disorder diagnosis codes, we identified 1244 TGD veterans (65+ years of age) receiving care in the Veterans Health Administration (VHA) from 2006 to 2018. These TGD veterans were then matched to 3732 cisgender veterans based on age, VHA site, and date of care in VHA. Results: In adjusted models, TGD veterans compared with cisgender veterans were less likely to have alcohol use disorder (adjusted odds ratio [AOR; 95% confidence interval]: [0.70; 0.58-0.85]), drug use disorder (0.59; 0.47-0.74), tobacco use (0.75; 0.65-0.86), and anxiety (0.74; 0.62-0.90). However, compared with cisgender veterans, TGD veterans were more likely to experience depression (1.63; 1.39-1.93), Alzheimer's disease (8.95; 4.25-18.83), cancer (1.83; 1.56-2.14), violence (1.82; 1.14-2.91), social/familial problems (2.45; 1.99-3.02), lack of access to care/transportation (2.23; 1.48-3.37), and military sexual trauma (2.59; 1.93-3.46). Furthermore, compared with cisgender veterans, TGD veterans were more likely to have documentation of a higher count of social stressors: 1 or more stressors (1.64; 1.38-1.95) and 2 or more stressors (1.22; 1.01-1.49). Conclusion: Despite significant disparities in social stressors and health conditions compared with cisgender veterans, TGD veterans had a lower likelihood of substance use and anxiety. Interventions are needed to mitigate social stressors and improve health among the older TGD veteran population.

Alcohol-attributable deaths and years of potential life lost due to alcohol among veterans: Overall and between persons with minoritized and non-minoritized sexual orientations

BACKGROUND

Unhealthy alcohol use is disproportionally experienced by individuals with minoritized sexual orientations. Unlike the general US population, for whom the burden of alcohol as it relates to mortality is consistently monitored across time with national survey data, the impact of unhealthy alcohol use among veterans with minoritized sexual orientations, for whom addressing substance use is a national priority, is largely unknown.

METHODS

Using Alcohol Use Disorders Identification Test Consumption data from the Department of Veterans Affairs electronic health record and underlying cause of death from National Death Index from 2014 to 2018 we quantified alcohol consumption and related mortality among veterans with (n = 102,085) and without minoritized sexual orientations (n = 5300,521). Age adjusted rates of alcohol attributed deaths (AAD) per 100,000 persons and years of potential life lost (YPLL) were estimated by sexual orientation, sex, and sexual orientation stratified by sex.

RESULTS

Alcohol attributable deaths (n = 21,861) were higher among veterans with minoritized sexual orientations than veterans without after adjustment for age (486.5 deaths/100,000 versus 309.7 deaths/100,000, respectively). Veterans with minoritized sexual orientations also experienced more YPLL (13,772.8 years/100,000 versus 7618.9 years/100,000). Years of potential life lost per AAD was higher in women (33.2 years) than men (18.7 years).

CONCLUSIONS

Alcohol consumption results in substantial disability and death among veterans, particularly veterans with minoritized sexual orientations. Findings suggest need for increased alcohol-related services for all VA patients, and potential targeted approaches to for veterans with minoritized sexual orientations and women to offset risk for, and years of potential life lost from, alcohol attributable death.

Annual HIV screening rates for HIV-negative men who have sex with men in primary care

Background

Men who have sex with men (MSM) account for most new HIV diagnoses in the US. Annual HIV testing is recommended for sexually active MSM if HIV status is negative or unknown. Our primary study aim was to determine annual HIV screening rates in primary care across multiple years for HIV-negative MSM to estimate compliance with guidelines. A secondary exploratory endpoint was to document rates for non-MSM in primary care.

Methods

We conducted a three-year retrospective cohort study, analyzing data from electronic medical records of HIV-negative men aged 18 to 45 years in primary care at a large academic health system using inferential and logistic regression modeling.

Results

Of 17,841 men, 730 (4.1%) indicated that they had a male partner during the study period. MSM were screened at higher rates annually than non-MSM (about 38% vs. 9%, p<0.001). Younger patients (p-value<0.001) and patients with an internal medicine primary care provider (p-value<0.001) were more likely to have an HIV test ordered in both groups. For all categories of race and self-reported illegal drug use, MSM patients had higher odds of HIV test orders than non-MSM patients. Race and drug use did not have a significant effect on HIV orders in the MSM group. Among non-MSM, Black patients had higher odds of being tested than both White and Asian patients regardless of drug use.

Conclusions

While MSM are screened for HIV at higher rates than non-MSM, overall screening rates remain lower than desired, particularly for older patients and patients with a family medicine or pediatric PCP. Targeted interventions to improve HIV screening rates for MSM in primary care are discussed.

A scoping review of ethics considerations in clinical natural language processing

Objectives

To review through an ethics lens the state of research in clinical natural language processing (NLP) for the study of bias and fairness, and to identify gaps in research.

Methods

We queried PubMed and Google Scholar for articles published between 2015 and 2021 concerning clinical NLP, bias, and fairness. We analyzed articles using a framework that combines the machine learning (ML) development process (ie, design, data, algorithm, and critique) and bioethical concepts of beneficence, nonmaleficence, autonomy, justice, as well as explicability. Our approach further differentiated between biases of clinical text (eg, systemic or personal biases in clinical documentation towards patients) and biases in NLP applications.

Results

Out of 1162 articles screened, 22 met criteria for full text review. We categorized articles based on the design (N = 2), data (N = 12), algorithm (N = 14), and critique (N = 17) phases of the ML development process.

Discussion

Clinical NLP can be used to study bias in applications reliant on clinical text data as well as explore biases in the healthcare setting. We identify 3 areas of active research that require unique ethical considerations about the potential for clinical NLP to address and/or perpetuate bias: (1) selecting metrics that interrogate bias in models; (2) opportunities and risks of identifying sensitive patient attributes; and (3) best practices in reconciling individual autonomy, leveraging patient data, and inferring and manipulating sensitive information of subgroups. Finally, we address the limitations of current ethical frameworks to fully address concerns of justice. Clinical NLP is a rapidly advancing field, and assessing current approaches against ethical considerations can help the discipline use clinical NLP to explore both healthcare biases and equitable NLP applications.

Sexual orientation-related disparities in health conditions that elevate COVID-19 severity

Purpose

The Veterans Health Administration (VA) is the largest single integrated healthcare system in the US and is likely the largest healthcare provider for people with minoritized sexual orientations (e.g., gay, lesbian, bisexual). The purpose of this study was to use electronic health record (EHR) data to replicate self-reported survey findings from the general US population and assess whether sexual orientation is associated with diagnosed physical health conditions that may elevate risk of COVID-19 severity among veterans who utilize the VA.

Methods

A retrospective analysis of VA EHR data from January 10, 1999–January 07, 2019 analyzed in 2021. Veterans with minoritized sexual orientations were included if they had documentation of a minoritized sexual orientation within clinical notes identified via natural language processing. Veterans without minoritized sexual orientation documentation comprised the comparison group. Adjusted prevalence and prevalence ratios (aPR) were calculated overall and by race/ethnicity while accounting for differences in distributions of sex assigned at birth, age, calendar year of first VA visit, volumes of healthcare utilization, and VA priority group.

Results

Data from 108,401 veterans with minoritized sexual orientation and 6,511,698 controls were analyzed. After adjustment, veterans with minoritized sexual orientations had a statistically significant elevated prevalence of 10 of the 11 conditions. Amongst the highest disparities observed were COPD (aPR:1.24 [95% confidence interval:1.23–1.26]), asthma (1.22 [1.20–1.24]), and stroke (1.26 [1.24–1.28]).

Conclusions

Findings largely corroborated patterns among the general US population. Further research is needed to determine if these disparities translate to poorer COVID-19 outcomes for individuals with minoritized sexual orientation.

Implementation of Gender Identity and Assigned Sex at Birth Data Collection in Electronic Health Records: Where Are We Now?

In 2015, the United States Department of Health and Human Services instantiated rules mandating the inclusion of sexual orientation and gender identity (SO/GI) data fields for systems certified under Stage 3 of the Meaningful Use of Electronic Health Records (EHR) program. To date, no published assessments have benchmarked implementation penetration and data quality. To establish a benchmark for a U.S. health system collection of gender identity and sex assigned at birth, we analyzed one urban academic health center's EHR data; specifically, the records of patients with unplanned hospital admissions during 2020 (N = 49,314). Approximately one-quarter of patient records included gender identity data, and one percent of them indicated a transgender or nonbinary (TGNB) status. Data quality checks suggested limited provider literacy around gender identity as well as limited provider and patient comfort levels with gender identity disclosures. Improvements are needed in both provider and patient literacy and comfort around gender identity in clinical settings. To include TGNB populations in informatics-based research, additional novel approaches, such as natural language processing, may be needed for more comprehensive and representative TGNB cohort discovery. Community and stakeholder engagement around gender identity data collection and health research will likely improve these implementation efforts.
