Improvement in Breast Reconstruction Disparities following Medicaid Expansion under the Affordable Care Act

Racial and ethnic disparities in reception of muscle flap closure during oncologic spinal surgery

BACKGROUND

Racial disparities persist in surgical outcomes after spine surgery for primary and metastatic cancers. Muscle flap closure of spinal defects after oncologic resection has been shown to reduce wound complication rate with favorable cost-effectiveness. It is currently unknown whether racial disparities may affect the reception of this treatment.

METHODS

Spinal surgery procedures for tumor resection and subsequent reconstruction were identified in the 2011-2022 National Surgical Quality Improvement Program databases. Cases were propensity score matched for covariates like age, comorbidities, number of vertebral levels reconstructed, and length of stay to isolate the predictive impact of race on reception of muscle flap closure (p < 0.05).

RESULTS

A total of 9467 patients who underwent oncologic spine surgery and had known race and ethnicity were identified in the final cohort. Two hundred thirty-two (2.5%) cases included muscle flap closure during the index surgery. After matching (n = 4196), minority race/ethnicity was associated with lower rates of muscle flap closure (2.2%) than non-Hispanic White race/ethnicity (3.8%) (p = 0.0037). Upon weighted univariate logistic regression, minority racial and ethnic identification also predicted lower likelihood of muscle flap closure (OR: 0.57, 95% CI: 0.52-0.63, p < 0.001). Among patients who received muscle flap closure, the overall rate of all major or minor thirty-day postoperative complications was not different depending on race and ethnicity (p > 0.05).

CONCLUSION

There are evident racial disparities in the reception of muscle flap closure after oncologic spine surgery. Further work may investigate the role of intersecting socioeconomic factors like insurance status and hospital characteristics.

LAY SUMMARY

Muscle flap closure is a surgical technique within plastic surgery that has been associated with lower rates of complications after spine surgery to remove tumors. Our study shows that minority racial and ethnic groups are less likely on average to receive muscle flap closure.

Disaggregation of Asian American, Native Hawaiian, and Pacific Islander populations in postmastectomy breast reconstruction

PURPOSE

Asian American, Native Hawaiian, and Pacific Islander (AANHPI) patient populations are often defined as one monolithic group in medical research despite cultural, socioeconomic, and clinical heterogeneity. Although the general AANHPI population is underrepresented in reception of postmastectomy breast reconstruction, existing literature has not characterized the disaggregation of such rates for AANHPI ethnic subgroups.

METHODS

Patients who underwent mastectomy were identified in the 2007 to 2020 registries within the Surveillance, Epidemiology and End Results database. Patients were stratified by race and ethnicity, and additional demographic and oncologic variables were collected. Multivariate binary logistic regression was conducted to assess for reception of postmastectomy immediate breast reconstruction (p < 0.05).

RESULTS

Among 33,422 AANHPI patients who underwent mastectomy, South Asian patients were associated with the highest breast reconstruction rates (33%) and Melanesians with the lowest (15%). Overall, AANHPI patients were associated with a lower breast reconstruction rate than non-Hispanic Whites (27% vs. 35%; p < 0.001). This difference increased from 6.4% in 2007 to 10% in 2020. After controlling for demographic and oncologic covariates, all AANHPI ethnic subgroups predicted a lower likelihood of breast reconstruction than non-Hispanic Whites (p < 0.001). Odds ratios for reconstruction ranged from 0.17 [95% confidence interval (95% CI), 0.11-0.27] for Melanesian patients to 0.45 (95% CI, 0.42-0.48) for South Asian patients.

CONCLUSIONS

Disparities in the receipt of immediate breast reconstruction exist within the AANHPI patient population in the United States. This analysis supported the need for disaggregation in plastic surgery research for improved knowledge and targeted interventions.

Post-Mastectomy Breast Reconstruction Disparities: A Systematic Review of Sociodemographic and Economic Barriers

Background: Breast reconstruction (BR) following mastectomy is a well-established beneficial medical intervention for patient physical and psychological well-being. Previous studies have emphasized BR as the gold standard of care for breast cancer patients requiring surgery. Multiple policies have improved BR access, but there remain social, economic, and geographical barriers to receiving reconstruction. Threats to equitable healthcare for all breast cancer patients in America persist despite growing awareness and efforts to negate these disparities. While race/ethnicity has been correlated with differences in BR rates and outcomes, ongoing research outlines a multitude of issues underlying this variance. Understanding the current and continuous barriers will help to address and overcome gaps in access. Methods: A systematic review assessing three reference databases (PubMed, Web of Science, and Ovid Medline) was carried out in accordance with PRISMA 2020 guidelines. A keyword search was conducted on 3 February 2024, specifying results between 2004 and 2024. Studies were included based on content, peer-reviewed status, and publication type. Two independent reviewers screened results based on title/abstract appropriateness and relevance. Data were extracted, cached in an online reference collection, and input into a cloud-based database for analysis. Results: In total, 1756 references were populated from all databases (PubMed = 829, Ovid Medline = 594, and Web of Science = 333), and 461 duplicate records were removed, along with 1147 results deemed ineligible by study criteria. Then, 45 international or non-English results were excluded. The screening sample consisted of 103 publications. After screening, the systematic review produced 70 studies with satisfactory relevance to our study focus. Conclusions: Federal mandates have improved access to women undergoing postmastectomy BR, particularly for younger, White, privately insured, urban-located patients. Recently published studies had a stronger focus on disparities, particularly among races, and show continued disadvantages for minorities, lower-income, rural-community, and public insurance payers. The research remains limited beyond commonly reported metrics of disparity and lacks examination of additional contributing factors. Future investigations should elucidate the effect of these factors and propose measures to eliminate barriers to access to BR for all patients.

Correlating state-specific and national trends in breast reconstruction after Medicaid expansion: A decade-long update on the Affordable Care Act's impact

While disparities in access to reconstruction persist, a comprehensive analysis comparing state-based outcomes and national patterns in breast reconstruction as a result of Medicaid expansion has never been examined. In this study, we investigated how breast reconstruction rates changed as a result of Medicaid expansion and compared these state-based findings to national counterparts. Patient data from the Healthcare Cost and Utilization Project among states that chose to expand Medicaid were compared with those from states that did not expand. The difference-in-differences estimate of expansion to nonexpansion states was 7.05 (p = 0.10) for implant-based reconstruction, -11.56 (p = 0.01) for autologous reconstruction, and -7.08 (p = 0.18) for overall reconstruction. Comparing rates of nonexpansion states to national trends yielded estimates of -0.06 (p = 0.04), 0.06 (p = 0.01), and 0.004 (p = 0.90) for implant-based, autologous, and overall breast reconstruction, respectively. Similarly, comparing rates of expansion states to national trends yielded estimates of 0.02 (p = 0.38), -0.05 (p = 0.03), and -0.02 (p = 0.44) for implant-based, autologous, and overall breast reconstruction, respectively. In this study on national health policy, Medicaid expansion was associated with a significant increase in autologous rates while state-specific trends alone did not appear to predict the national outcomes of sweeping legislative changes that were differentially applied among states.

Predictors of Complications in Autologous Breast Reconstruction Using DIEP Flaps: Implications for Management

BACKGROUND

Deep inferior epigastric perforator (DIEP) flaps are the standard for autologous breast reconstruction. This study investigated risk factors for DIEP complications in a large, contemporary cohort to optimize surgical evaluation and planning.

METHODS

This retrospective study included patients who underwent DIEP breast reconstruction between 2016 and 2020 at an academic institution. Demographics, treatment, and outcomes were evaluated in univariable and multivariable regression models for postoperative complications.

RESULTS

In total, 802 DIEP flaps were performed in 524 patients (mean age, 51.2 ± 9.6 years; mean body mass index, 29.3 ± 4.5). Most patients (87%) had breast cancer; 15% were BRCA -positive. There were 282 (53%) delayed and 242 (46%) immediate reconstructions and 278 (53%) bilateral and 246 (47%) unilateral reconstructions. Overall complications occurred in 81 patients (15.5%), including venous congestion (3.4%), breast hematoma (3.6%), infection (3.6%), partial flap loss (3.2%), total flap loss (2.3%), and arterial thrombosis (1.3%). Longer operative time was significantly associated with bilateral immediate reconstructions and higher body mass index. Prolonged operative time (OR, 1.16; P = 0.001) and immediate reconstruction (OR, 1.92; P = 0.013) were significant predictors of overall complications. Partial flap loss was associated with bilateral immediate reconstructions, higher body mass index, current smoking status, and longer operative time.

CONCLUSIONS

Prolonged operative time is a significant risk factor for overall complications and partial flap loss in DIEP breast reconstruction. For each additional hour of surgical time, the risk of developing overall complications increases by 16%. These findings suggest that reducing operative time through co-surgeon approaches, consistency in surgical teams, and counseling patients with more risk factors toward delayed reconstructions may mitigate complications.

Racial disparities in postmastectomy breast reconstruction following implementation of the affordable care act: A systematic review using a minority health and disparities research framework

BACKGROUND

This systematic review assesses racial disparities for African American (AA) women in breast reconstruction following the implementation of the Affordable Care Act.

METHODS

Four databases (Ovid Medline, PubMed, Scopus, Web of Science) were searched for peer-reviewed articles published between January 2011 and September 2021.

RESULTS

Out of 917 screened articles, 61 were included. The most common metrics were breast reconstruction rates (57.4%) and clinical outcomes (14.8%). Pooled reconstruction rates were 45.7% in white and 38.5% in AA women. 95.1% of studies found disparities in breast reconstruction rates. The greatest influencers on reconstruction rates were individual interactions in the healthcare system (54%), sociocultural environment (39%), behavioral factors (31%), and community interactions with the healthcare system (36%).

CONCLUSION

Racial disparities in postmastectomy breast reconstruction persist. Focusing on implicit bias, communication barriers and infrastructure are the most promising strategies to create equitable access to breast reconstruction for AA women.

Barriers to breast reconstruction for socioeconomically disadvantaged women

PURPOSE

Socioeconomic disparities in post-mastectomy breast reconstruction exist. Key informants have suggested that finding providers who accept Medicaid insurance and longer travel time to a plastic surgeon are important barriers. Our objective was to assess the relationship between these factors and reconstruction for socioeconomically disadvantaged women in Wisconsin.

METHODS

We identified women < 75 years of age with stage 0-III breast cancer who underwent mastectomy using the Wisconsin Cancer Reporting System. Women in the most disadvantaged state-based tertile of the Area Deprivation Index were included (n = 1809). Geocoding determined turn-by-turn drive time from women's address to the nearest accredited Commission on Cancer or National Accreditation Program for Breast Centers. Multivariable logistic regression determined the relationship between reconstruction, Medicaid, and travel time, controlling for patient factors known to impact reconstruction. Average adjusted predicted probabilities of receiving reconstruction were calculated.

RESULTS

Most patients had early-stage breast cancer (51% stage 0/I) and 15.2% had Medicaid. 37% of women underwent reconstruction. Socioeconomically disadvantaged women with Medicaid (OR = 0.62, 95% CI 0.46-0.84) and longer travel times (OR = 0.99, 95% CI 0.99-1.0) were less likely to receive reconstruction. Patients with the lowest predicted probability of reconstruction were those with Medicaid who lived furthest from a plastic surgeon.

CONCLUSION

Among socioeconomically disadvantaged women, Medicaid and travel remained associated with lower rates of reconstruction. Further work will explore opportunities to improve access to reconstruction for women with Medicaid. This is particularly challenging as it may require socioeconomically disadvantaged women to travel further to receive care.

Persistent and interdependent: Racial disparities and their mechanisms in postmastectomy breast reconstruction

BACKGROUND

Racial disparities in accessing postmastectomy breast reconstruction persist despite expansion of insurance coverage. An updated examination with a broad assessment of mediating factors in a "majority minority" community is needed.

METHODS

Data were collected on all patients undergoing mastectomy for breast cancer from 2011 to 2019 in a private academic center and adjacent safety-net hospital. Multivariable logistic regression was used to assess the effect of race on postmastectomy breast reconstruction, controlling for predetermined potentially mediating and confounding variables.

RESULTS

Of 1,554 patients, 63.8% (n = 203) of non-Hispanic White, 33.4% (n = 102) of Black, and 47.9% (n = 438) of Hispanic patients underwent postmastectomy breast reconstruction. Multivariable logistic regression showed that Black patients (odds ratio [OR] 3.6, 95% confidence internal [CI]: 2.2-5.9; P < .0001) undergo significantly less postmastectomy breast reconstruction than White patients. Age, insurance status, stage, and hospital type mediated this relationship.

CONCLUSION

Black patients have substantially reduced rates of postmastectomy breast reconstruction compared with White patients, which is mediated by socioeconomic factors.
