Associations between Race/Ethnicity, Uterine Fibroids, and Minimally Invasive Hysterectomy in the VA Healthcare System

Surgical Management of Fibroids: A Changing Landscape

Background: Uterine fibroids affect patients' quality of life and contribute significantly to health care costs. Studies from 2009 to 2011 demonstrated that fibroids disproportionately affect Black women, with lower odds of uterine preservation and minimally invasive approaches. Objective: This is a retrospective cohort study of data abstracted from the National Surgical Quality Improvement Program database from 2015 to 2019 examining trends in surgical management of uterine fibroids and exploring disparities in surgical approach in a modern cohort. Results: In total, 52,909 women underwent hysterectomy and 15,485 women underwent myomectomy between 2015 and 2019. Over the study period, the overall number of surgeries for fibroids increased by 44.2% with minimally invasive hysterectomy responsible for the majority of this increase. The proportion of patients who underwent myomectomy significantly increased (20.85% to 24.62%, p value <0.0001), whereas hysterectomy significantly decreased (79.15% to 75.38%, p value <0.0001). Bivariate analysis identified younger age, non-White race, and body mass index (BMI) <25 as significantly associated with performance of myomectomy. Non-Hispanic Black (adjusted odds ratio [aOR]: 3.55, 95% confidence interval [CI]: 3.23-3.89), Asian (aOR: 3.26, 95% CI: 2.80-3.80), and Hispanic Black (aOR: 5.50, 95% CI: 3.29-9.25) women were more likely to undergo myomectomy than non-Hispanic White women. Conclusion: Surgical treatment for fibroids increased over time, shifting toward uterine preservation. Myomectomy performance is associated with lower age and BMI and identifying as a racial and/or ethnic minority. These trends may represent improved access to surgical treatment of fibroids, resulting from the growth of minimally invasive gynecological surgery as a specialty and advocacy for equitable health care for all patients.

Uterine Fibroids

This JAMA Insights in the Women’s Health series discusses the incidence, diagnosis, and treatment of uterine fibroids.

Uterine fibroids and longitudinal profiles of the vaginal microbiota in a cohort presenting for transvaginal ultrasound

Bacterial vaginosis, characterized in part by low levels of vaginal Lactobacillus species, has been associated with pro-inflammatory cytokines which could fuel uterine fibroid development. However, prior work on the associations between uterine fibroids and vaginal bacteria is sparse. Most studies have focused on assessment of individual taxa in a single sample. To address research gaps, we sought to compare short, longitudinal profiles of the vaginal microbiota in uterine fibroid cases versus controls with assessment for hormonal contraceptives (HCs), a possible confounder associated with both protection from fibroid development and increases in Lactobacillus-dominated vaginal microbiota. This is a secondary analysis of 83 reproductive-age cisgender women who presented for transvaginal ultrasound (TVUS) and self-collected mid-vaginal swabs daily for 1-2 weeks before TVUS (Range: 5-16 days, n = 697 samples). Sonography reports detailed uterine fibroid characteristics (N = 21 cases). Vaginal microbiota was assessed by 16S rRNA gene amplicon sequencing and longitudinal microbiota profiles were categorized by hierarchical clustering. We compared longitudinal profiles of the vaginal microbiota among fibroid cases and controls with exact logistic regression. Common indications for TVUS included pelvic mass (34%) and pelvic pain (39%). Fibroid cases tended to be older and report Black race. Cases less often reported HCs versus controls (32% vs. 58%). A larger proportion of cases had low-Lactobacillus longitudinal profiles (48%) than controls (34%). In unadjusted analysis, L. iners-dominated and low-Lactobacillus profiles had higher odds of fibroid case status compared to other Lactobacillus-dominated profiles, however these results were not statistically significant. No association between vaginal microbiota and fibroids was observed after adjusting for race, HC and menstruation. Results were consistent when number of fibroids were considered. There was not a statistically significant association between longitudinal profiles of vaginal microbiota and uterine fibroids after adjustment for common confounders; however, the study was limited by small sample size.

"I Wasn't Presented With Options": Perspectives of Black Veterans Receiving Care for Uterine Fibroids in the Veterans Health Administration

INTRODUCTION

Black women with uterine fibroids experience greater symptom severity and worse treatment outcomes compared with their White counterparts. Black veterans who use Veterans Health Administration (VA) health care experience similar disparities. This study investigated the experiences of Black veterans receiving care for uterine fibroids at VA.

METHODS

We identified Black veterans aged 18 to 54 years with newly diagnosed symptomatic uterine fibroids between the fiscal years 2010 and 2012 using VA medical record data, and we recruited participants for interviews in 2021. We used purposive sampling by the last recorded fibroid treatment in the data (categorized as hysterectomy, other uterine-sparing treatments, and medication only/no treatment) to ensure diversity of treatment experiences. In-depth semistructured interviews were conducted to gather rich narratives of veterans' uterine fibroid care experiences. Transcribed interviews were analyzed using content analysis.

RESULTS

Twenty Black veterans completed interviews. Key themes that emerged included the amplified impact of severe fibroid symptoms in male-dominated military culture; the presence of multilevel barriers, from individual to health care system factors, that delayed access to high-quality treatment; insufficient treatments offered; experiences of interpersonal racism and provider bias; and the impact of fertility loss related to fibroids on mental health and intimate relationships. Veterans with positive experiences stressed the importance of finding a trustworthy provider and self-advocacy.

CONCLUSIONS

System-level interventions, such as race-conscious and person-centered care training, are needed to improve care experiences and outcomes of Black veterans with fibroids.

Health Care Disparities in Patients Undergoing Hysterectomy for Benign Indications: A Systematic Review

OBJECTIVE

To explore how markers of health care disparity are associated with access to care and outcomes among patients seeking and undergoing hysterectomy for benign indications.

DATA SOURCES

PubMed, EMBASE, and ClinicalTrials.gov were searched through January 23, 2022.

METHODS OF STUDY SELECTION

The population of interest included patients in the United States who sought or underwent hysterectomy by any approach for benign indications. Health care disparity markers included race, ethnicity, geographic location, insurance status, and others. Outcomes included access to surgery, patient level outcomes, and surgical outcomes. Eligible studies reported multivariable regression analyses that described the independent association between at least one health care disparity risk marker and an outcome. We evaluated direction and strengths of association within studies and consistency across studies.

TABULATION, INTEGRATION, AND RESULTS

Of 6,499 abstracts screened, 39 studies with a total of 46 multivariable analyses were included. Having a Black racial identity was consistently associated with decreased access to minimally invasive, laparoscopic, robotic, and vaginal hysterectomy. Being of Hispanic ethnicity and having Asian or Pacific Islander racial identities were associated with decreased access to laparoscopic and vaginal hysterectomy. Black patients were the only racial or ethnic group with an increased association with hysterectomy complications. Medicare insurance was associated with decreased access to laparoscopic hysterectomy, and both Medicaid and Medicare insurance were associated with increased likelihood of hysterectomy complications. Living in the South or Midwest or having less than a college degree education was associated with likelihood of prior hysterectomy.

CONCLUSION

Studies suggest that various health care disparity markers are associated with poorer access to less invasive hysterectomy procedures and with poorer outcomes for patients who are undergoing hysterectomy for benign indications. Further research is needed to understand and identify the causes of these disparities, and immediate changes to our health care system are needed to improve access and opportunities for patients facing health care disparities.

Racial Disparities in Uterine Fibroid Treatment Among Veterans Using VA Health Care

INTRODUCTION

Uterine fibroids are common, nonmalignant tumors that disproportionately impact Black patients. We aimed to examine Black and White differences in receipt of any treatment and type of first treatment in the Department of Veterans Affairs, including effect modification by severity as approximated by anemia.

METHODS

We used Department of Veterans Affairs administrative data to identify 5,041 Black and 3,206 White veterans with symptomatic uterine fibroids, identified by International Classification of Diseases, 9th edition, Clinical Modification, codes, between fiscal year 2010 and fiscal year 2012 and followed in the administrative data through fiscal year 2018 for outcomes. Outcomes included receipt of any treatment, hysterectomy as first treatment, and fertility-sparing treatment as first treatment. We stratified all analyses by age (<45, ≥45 years old), used generalized linear models with a log link and Poisson error distribution, included an interaction term between race and anemia, and used recycled predictions to estimate adjusted percentages for outcomes.

RESULTS

There was evidence of effect modification by anemia for receipt of any treatment but not for any other outcomes. Across age and anemia sub-groups, Black veterans were less likely to receive any treatment than White veterans. Adjusted racial differences were most pronounced among veterans with anemia (<45 years, Black-White difference = -10.3 percentage points; 95% confidence interval, -15.9 to -4.7; ≥45 years, Black-White difference = -20.3 percentage points; 95% confidence interval, -27.8 to -12.7). Across age groups, Black veterans were less likely than White veterans to have hysterectomy and more likely to have a fertility-sparing treatment as their first treatment.

CONCLUSIONS

We identified significant Black-White disparities in receipt of treatment for symptomatic uterine fibroids. Additional research that centers the experiences of Black veterans with uterine fibroids is needed to inform strategies to eliminate racial disparities in uterine fibroid care.

Hysterectomy inequities between black and white patients in the US military health system: A retrospective cohort study

OBJECTIVE

To evaluate multicomponent aspects of hysterectomy-related care in the US Military Health System including the probability of open hysterectomy (versus vaginal or laparoscopic hysterectomy), probability of having a length of stay > 1 day, and discharge milligram morphine equivalent dose (MED). Analyses sought to identify the presence and strength of healthcare inequities between Black and white patients.

METHODS

In this retrospective cohort study, records of patients (N = 11,067) ages 18-65 years enrolled in TRICARE who underwent a hysterectomy between January 2017 to January 2021 in US military treatment facilities (direct care) or civilian facilities (purchased care) were included. Graphic representations illustrated provider and facility variation. Generalized additive mixed models (GAMMs) evaluated inequities across outcomes. Sensitivity analyses included only direct care receipt and added a random effect for the facility.

RESULTS

There was significant variation in provider use of open versus vaginal or laparoscopic hysterectomies, as well as provider and facility discharge MED. The GAMMs indicated Black patients were more likely to receive an open hysterectomy [log(OR) -0.54, (95 %CI -0.65, -0.43), p < 0.001] and have a length of stay > 1 day [log(OR) 0.18, (95 %CI 0.07, 0.30), p = 0.002], but had similar discharge MED [-2 mg (95% CI -7 mg, 3 mg), p = 0.51], relative to white patients. Patients receiving care in purchased care, relative to direct care, were more likely to receive a vaginal or laparoscopic hysterectomy [log(OR) 0.28, (95 %CI 0.17, 0.38), p = 0.002] and received approximately 21 mg lower discharge MED (95 %CI 16-26 mg less, p < 0.001), but were more likely to have a hospital stay > 1 day [log(OR) 0.95, (95 %CI 0.83, 0.1.10), p < 0.001]. Additional gynecological conditions (e.g., uterine fibroids) and prescription receipt were associated with some, but not all outcomes.

CONCLUSION

Improving timely care receipt, especially for uterine fibroids, increasing access to vaginal and laparoscopic hysterectomies, and reducing unwarranted variation in discharge MED could improve care quality and equity in the US Military Health System.

Racial disparities in uterine fibroids and endometriosis: a systematic review and application of social, structural, and political context

IMPORTANCE

Uterine fibroids and endometriosis are 2 of the leading causes of morbidity among reproductive-aged women. There are significant racial disparities in disease prevalence, incidence, age of onset, and treatment profile in fibroids. The data on endometriosis are less clear.

OBJECTIVE

To conduct a systematic review of racial disparities in prevalence of uterine fibroids and endometriosis in the United States and summarize the literature on these 2 highly prevalent benign gynecologic conditions using a framework that explicitly incorporates and acknowledges the social, structural, and political contexts as a root cause of racial disparities between Black and White women.

EVIDENCE REVIEW

A systematic review regarding racial disparities in prevalence of fibroids and endometriosis was conducted separately. Two separate searches were conducted in PubMed to identify relevant original research manuscripts and prior systematic reviews regarding racial disparities in uterine fibroids and endometriosis using standardized search terms. In addition, we conducted a structured literature search to provide social, structural, and political context of the disparities.

FINDINGS

A systematic review of the literature indicated that the prevalence of uterine fibroids was consistently higher in Black than in White women with the magnitude of the difference varying depending on population and case definition. Prevalence of endometriosis varied considerably depending on the base population and case definition, but was the same or lower among Black vs. White women. As a result of the social, structural, and political context in the United States, Black women disproportionately experience a range of exposures across the life course that may contribute to their increased uterine fibroid incidence, prevalence, and severity of uterine fibroids. However, data suggest no racial difference in the incidence of endometriosis. Nevertheless, Black women with fibroids or endometriosis experience worse clinical and surgical outcomes than their White counterparts.

CONCLUSION AND RELEVANCE

Racial disparities in uterine fibroids and endometriosis can be linked with differential exposures to suspected etiologic agents, lack of adequate access to health care, including highly skilled gynecologic surgeons, and bias and discrimination within the health care system. Eliminating these racial disparities will require solutions that address root causes of health disparities through policy, education and programs to ensure that all patients receive culturally- and structurally-competent care.

Uterine Weight as a Modifier of Black/White Racial Disparities in Minimally Invasive Hysterectomy Among Veterans with Fibroids in the Veterans Health Administration

Introduction

Uterine fibroids are the most common indication for hysterectomy. Minimally invasive hysterectomy (MIH) confers lower risk of complications and shorter recovery than open surgical procedures; however, it is more challenging to perform with larger fibroids. There are racialized differences in fibroid size and MIH rates. We examined the role of uterine size in black-white differences in MIH among Veterans in the Department of Veterans Affairs (VA).

Methods

Using VA clinical and administrative data, we conducted a cross-sectional study among black and white Veterans with fibroids who underwent hysterectomy between 2012 and 2014. We abstracted postoperative uterine weight from pathology reports as a proxy for uterine size. We used a generalized linear model to estimate the association between race and MIH and tested an interaction between race and postoperative uterine weight (≤250 g vs. >250 g). We estimated adjusted marginal effects for racial differences in MIH by postoperative uterine weight.

Results

The sample included 732 Veterans (60% black, 40% white). Postoperative uterine weight modified the association of race and MIH (p for interaction=0.05). Black Veterans with postoperative uterine weight ≤250 g had a nearly 12-percentage point decrease in MIH compared to white Veterans (95% CI -23.1 to -0.5), with no difference by race among those with postoperative uterine weight >250 g.

Discussion

The racial disparity among Veterans with small fibroids who should be candidates for MIH underscores the role of other determinants beyond uterine size. To eliminate disparities in MIH, research focused on experiences of black Veterans, including pathways to treatment and provider-patient interactions, is needed.

Trends and predictors of hysterectomy prevalence among women in the United States

BACKGROUND

Hysterectomy is the most common nonobstetrical medical procedure performed in US women. Evaluating hysterectomy prevalence trends and determinants is important for estimating gynecologic cancer rates and management of uterine conditions.

OBJECTIVE

This study aimed to assess hysterectomy prevalence trends and determinants using the Behavioral Risk Factor Surveillance System (2006-2016).

STUDY DESIGN

We estimated crude hysterectomy prevalences and multivariable-adjusted odds ratios and 95% confidence intervals for associations of race or ethnicity, age group (5-year), body mass index (categorical), smoking status, education, insurance, income, and US region with hysterectomy. Missing data were imputed. The number of women in each survey year ranged from 220,302 in 2006 to 275,631 in 2016.

RESULTS

Although overall hysterectomy prevalence changed little between 2006 and 2016 (21.4% and 21.1%, respectively), hysterectomy prevalence was lower in 2016 than in 2006 among women aged ≥40 years, particularly among non-Hispanic Black and Hispanic women. Current smoking (odds ratio, 1.38; 95% confidence interval, 1.35-1.41), increasing age (odds ratio, 1.40; 95% confidence interval, 1.39-1.40), living in the South compared with the Midwest (odds ratio, 1.36; 95% confidence interval, 1.34-1.39), higher body mass index (odds ratio, 1.26; 95% confidence interval, 1.25-1.27), Black race compared with White (odds ratio, 1.10; 95% confidence interval, 1.07-1.13), and having insurance compared with being uninsured (odds ratio, 1.26; 95% confidence interval, 1.22-1.30) were most strongly associated with increased prevalence. Hispanic ethnicity and living in the Northeast were most strongly associated with decreased prevalence (odds ratio, 0.73; 95% confidence interval, 0.70-0.76; odds ratio, 0.67; 95% confidence interval, 0.65-0.69).

CONCLUSION

Nationwide hysterectomy prevalence decreased among women aged ≥40 years from 2006 to 2016, particularly among non-Hispanic Black and Hispanic women. Age, non-Hispanic Black race, having insurance, current smoking, and living in the South were associated with increased odds of hysterectomy, even after accounting for possible explanatory factors. Further research is needed to better understand associations of race and ethnicity and region with hysterectomy prevalence.

Social Vulnerability Index and Surgical Management of Abnormal Uterine Bleeding in Reproductive-Age Women

STUDY OBJECTIVE

To determine whether surgical management of abnormal uterine bleeding (AUB) is associated with Social Vulnerability Index (SVI).

DESIGN

Retrospective cohort.

SETTING

Seven hospitals and four ambulatory surgery centers within large New York health system.

PATIENTS

All patients 15-45 years of age who underwent either a hysterectomy or myomectomy for AUB between January 2019 and October 2021.

INTERVENTIONS

None. Home addresses were linked to Census tracts and SVI scores. SVI is composed of 4 themes that potentially influence a community's vulnerability to health stressors: socioeconomic status, household composition and disability, minority status and language, and housing type and transportation. Multiple logistic regression analyses were performed to evaluate the association between SVI and surgical procedure/approach, adjusting for: age, race and ethnicity, marital status, insurance, language, body mass index, and prior abdominal surgery.

MEASUREMENTS AND MAIN RESULTS

A total of 1,628 patients were included. On regression analysis between SVI quarters and type of surgery, the odds of laparotomy for the hysterectomy group were not impacted by SVI composite score both before and after adjusting for alternative factors (OR and aOR). Amongst those who had a myomectomy, individuals in SVI Q3 had 1.86 (95% CI: 1.27 to 2.72) higher odds of having a laparotomy versus those in SVI Q1. Individuals in SVI Q4 had 1.74 (95% CI: 1.15 to 2.62) higher odds of having a laparotomy versus those in SVI Q1. While some unadjusted odds ratios were statistically significant in the myomectomy group, when adjusted for social, demographic and economic factors the results were not statistically significant.

CONCLUSION

Patients living in more vulnerable communities are less likely to have minimally invasive hysterectomy or myomectomy for management of AUB. Neighborhood characteristics are independently associated with surgical procedure and approach.

Development of an algorithm to assess unmeasured symptom severity in gynecologic care

BACKGROUND

Healthcare disparities research is often limited by incomplete accounting for differences in health status by populations. In the United States, hysterectomy shows marked variation by race and geography, but it is difficult to understand what factors cause these variations without accounting for differences in the severity of gynecologic symptoms that drive the decision-making for hysterectomy.

OBJECTIVE

This study aimed to demonstrate a method for using electronic health record-derived data to create composite symptom severity indices to more fully capture relevant markers that influence the decision for hysterectomy.

STUDY DESIGN

This was a retrospective cohort study of 1993 women who underwent hysterectomy between April 4, 2014, and December 31, 2017, from 10 hospitals and >100 outpatient clinics in North Carolina. Electronic health record data, including billing, pharmacy, laboratory data, and free-text notes, were used to identify markers of 3 common indications for hysterectomy: bulk symptoms (pressure from uterine enlargement), vaginal bleeding, and pelvic pain. To develop weighted symptom indices, we finalized a scoring algorithm based on the relationship of each marker to an objective measure, in combination with clinical expertise, with the goal of composite symptom severity indices that had sufficient variation to be useful in comparing different patient groups and allow discrimination among severe symptoms of bulk, bleeding, or pain.

RESULTS

The ranges of symptom severity scores varied across the 3 indices, including composite bulk score (0-14), vaginal bleeding score (0-44), and pain score (0-30). The mean values of each composite symptom severity index were greater for those who had diagnostic codes for vaginal bleeding, bulk symptoms, or pelvic pain, respectively. However, each index demonstrated a variation across the entire group of hysterectomy cases and identified symptoms that ranged in severity among those with and without the target diagnostic codes.

CONCLUSION

Leveraging multisource data to create composite symptom severity indices provided greater discriminatory power to assess common gynecologic indications for hysterectomy. These methods can improve the understanding in healthcare use in the setting of long-standing inequities and be applied across populations to account for previously unexplained variations across race, geography, and other social indicators.

Each Uterus Counts: A narrative review of health disparities in benign gynaecology and minimal access surgery

INTRODUCTION

Health disparities exposed by the Covid-19 pandemic have prompted healthcare professionals to investigate disparities within their own specialty. Racial and ethnic disparities in obstetrics are well documented but inequities in gynaecology are less well known. Our aim is to review the literature on two commonly performed procedures, hysterectomy and myomectomy, and one condition, ectopic pregnancy, to evaluate the prevalence of racial, ethnic and socioeconomic disparities in benign gynaecology and minimal access surgery.

METHODS

A narrative review of 33 articles identified from a Pubmed using the following search criteria; "race"; "ethnicity"; "socioeconomic status"; "disparity"; "inequity"; and "inequality". Case reports and papers assessing gynaecological malignancy were excluded.

RESULTS

Despite minimal access surgery having fewer complications and faster recovery than open surgery, US studies have shown that black and ethnic minority women are less likely than white women to have minimally invasive hysterectomies and myomectomies. Uninsured women and patients on Medicaid are also less likely to receive minimally invasive procedures. Contributing factors include fibroid size, geographic location and access to hospitals performing minimal access surgery, and the discontinuation of power morcellation. Ethnic minority women who receive minimally invasive myomectomy have been shown to have a higher risk of complications and prolonged recovery. Black and ethnic minority women also have a higher risk of morbidity and mortality from ectopic pregnancy and are more likely to receive surgical than medical management.

CONCLUSION

Extensive study from the US has demonstrated disparities in access to minimally invasive gynaecological surgery, whereas in the UK the data is infrequent, inconsistent and incomplete. Little is known about the influence of patient preference and counselling as well as institutional bias on health equity in gynaecology. Further research is necessary to identify interventions that mitigate these disparities in access and outcomes.

Contributors to Racial Disparities in Minimally Invasive Hysterectomy in the US Department of Veterans Affairs

BACKGROUND

Minimally invasive hysterectomy for fibroids decreases recovery time and risk of postoperative complications compared with abdominal hysterectomy. Within Veterans Affair (VA), black women with uterine fibroids are less likely to receive a minimally invasive hysterectomy than white women.

OBJECTIVE

To quantify the contributions of patient, facility, temporal and geographic factors to VA black-white disparity in minimally invasive hysterectomy.

RESEARCH DESIGN

A cross-sectional study.

SUBJECTS

Veterans with fibroids and hysterectomy performed in VA between October 1, 2012 and September 30, 2015.

MEASURES

Hysterectomy mode was defined using ICD-9 codes as minimally invasive (laparoscopic, vaginal, or robotic-assisted) versus abdominal. The authors estimated a logistic regression model with minimally invasive hysterectomy modeled as a function of 4 sets of factors: sociodemographic characteristics other than race, health risk factors, facility, and temporal and geographic factors. Using decomposition techniques, systematically substituting each white woman's characteristics for each black woman's characteristics, then recalculating the predicted probability of minimally invasive hysterectomy for black women for each possible combination of factors, we quantified the contribution of each set of factors to observed disparities in minimally invasive hysterectomy.

RESULTS

Among 1255 veterans with fibroids who had a hysterectomy at a VA, 61% of black women and 39% of white women had an abdominal hysterectomy. Our models indicated there were 99 excess abdominal hysterectomies among black women. The majority (n=77) of excess abdominal hysterectomies were unexplained by measured sociodemographic factors beyond race, health risk factors, facility, and temporal or geographic trends.

CONCLUSION

Closer examination of the equity of VA gynecology care and ways in which the VA can work to ensure equitable care for all women veterans is necessary.
