Positive impact of the Patient Protection and Affordable Care Act Medicaid expansion on Louisiana women with breast cancer

BACKGROUND

Louisiana is one of the few Southern states that enacted the Medicaid expansion of the Patient Protection and Affordable Care Act (ACA). To the authors' knowledge, the issue of how this has affected the breast cancer landscape in Louisiana is unknown. The authors have postulated that ACA expansion had a positive impact for Louisiana women diagnosed with breast cancer.

METHODS

Data from the Louisiana Tumor Registry regarding 14,640 women aged 20 to 64 years who resided in Louisiana and were diagnosed with American Joint Committee on Cancer stage 0 to stage IV breast cancer between 2012 and 2018 were analyzed. The study period was divided into 2 groups: 1) before ACA expansion (January 1, 2012-May 31, 2016); and 2) after ACA expansion (June 1, 2016-December 31, 2018). The chi-square test and multivariable logistic regression models were used to assess the impact of ACA expansion. A P value <.05 was considered statistically significant.

RESULTS

After ACA expansion, the rate of uninsured patients decreased from 5.4% to 3.0% (P < .0001), and the rate of Medicaid recipients increased from 11.6% to 17.7% (P < .0001). The diagnosis of stage I breast cancer increased from 36.8% to 44.7% (P < .0001), whereas the diagnosis of stage III breast cancer decreased from 10.7% to 8.5% (P < .0001). The receipt of radiotherapy after breast-conserving surgery increased from 81.2% to 84.0% (P = .0035), and the receipt of radiotherapy within 90 days increased from 57.2% to 61.7% (P = .0012). After adjustment for sociodemographic and clinical variables, the models demonstrated that ACA expansion decreased the uninsured rate by 48% (odds ratio [OR], 0.52; 95% CI, 0.43-0.63), increased the diagnosis of early-stage disease (stage0 to stage II) by 27% (OR, 1.27; 95% CI, 1.15-1.41), increased receipt of radiotherapy after breast-conserving surgery by 19% (OR, 1.19; 95% CI, 1.03-1.37), and reduced the delay of receipt of radiotherapy by 16% (OR, 0.84; 95% CI, 0.74-0.95).

CONCLUSIONS

ACA expansion in Louisiana reduced the uninsured rate, increased the diagnosis of early-stage disease, and increased access to treatment.

Change in stage of presentation of head and neck cancer in the United States before and after the affordable care act

OBJECTIVE/HYPOTHESIS

Early diagnosis and stage at presentation, two prognostic factors for survival among patients with head and neck cancer (HNC), are significantly impacted by a patient's health insurance status. We aimed to assess the impact of the Patient Protection and Affordable Care Act (ACA) on stage at presentation across socioeconomic and demographic subpopulations of HNC patients in the United States.

STUDY DESIGN

Retrospective data analysis.

METHODS

The National Cancer Database, a hospital-based cancer database (2011-2015), was queried for adults aged 18-64 years and diagnosed with a malignant primary HNC. The outcome of interest was change in early-stage diagnoses between 2011-2013 (pre-ACA) and 2014-2015 (post-ACA) using logistic regression models.

RESULTS

A total of 91,137 HNC cases were identified in the pre-ACA (n = 53,726) and post-ACA (n = 37,411) years. Overall, the odds of early-stage diagnoses did not change significantly post-ACA (aOR = 0.97, 95 % CI 0.94, 1.00; p = 0.081). However, based on health insurance status, HNC patients with Medicaid were significantly more likely to present with early-stage disease post-ACA (aOR = 1.12, 95 % CI 1.03, 1.21; p = 0.007). We did not observe increased odds of early-stage presentation for other insurance types. Males were less likely to present with early-stage disease, pre- or post-ACA.

CONCLUSIONS

We demonstrate a significant association between ACA implementation and increased early-stage presentation among Medicaid-enrolled HNC patients. This suggests that coverage expansions through the ACA may be associated with increased access to care and may yield greater benefits among low-income HNC patients.

Trends in guideline-adherent fertility-sparing surgery for early-stage cervical cancer before and after the Affordable Care Act

OBJECTIVE

To assess trends in guideline-adherent fertility-sparing surgery (GA-FSS) for early-stage cervical cancer relative to Patient Protection and Affordable Care Act (ACA) implementation.

METHODS

National Cancer Database patients treated for Stage IA1-IB1 cervical cancer from 2004 to 2016 were included. Multivariable logistic regression was used to determined trends in GA-FSS relative to the ACA and identify patient factors independently associated with GA-FSS.

RESULTS

Odds of GA-FSS increased in the post- compared to pre-ACA cohort (aOR = 1.65; 95%CI: 1.34-2.03). Decreasing age, Asian/Pacific Islander race, higher education and income levels, more recent treatment year, and lower clinical stage were independently associated with increased odds of receiving GA-FSS. In the pre- and post-ACA samples, decreasing age (per 1 year age increase; pre-ACA aOR = 0.87, 95%CI:0.85-0.90; post-ACA aOR = 0.85, 95%CI:0.83-0.87), higher education level (top vs. lowest education quartile; pre-ACA aOR = 2.08, 95%CI:1.19-3.65; post-ACA aOR = 2.00, 95%CI:1.43-2.80), and lower clinical stage (stages IA2 [pre-ACA aOR = 0.19, 95%CI:0.09-0.41; post-ACA aOR = 0.29, 95%CI:0.19-0.45] and IB1 [pre-ACA aOR = 0.06, 95%CI:0.06-0.16; post-ACA aOR = 0.16, 95%CI: 0.12-0.20] relative to stage IA1) were independently associated with increased odds of GA-FSS receipt. After the ACA, Asian/Pacific Islander race (aOR = 2.81, 95%CI: 1.81-4.36) and more recent treatment year (Spearman's ρ = 0.0348, p-value = 0.008) were also independently associated with increased odds of GA-FSS receipt. When adjusted for the pre- vs. post-ACA treatment periods, Medicaid patients were less likely to undergo GA-FSS than privately-insured patients (aOR = 1.65; 95%CI:1.34-2.03).

CONCLUSIONS

Patients were more likely to receive GA-FSS post-ACA. Though the proportion of publicly-insured women increased after ACA implementation, women on Medicaid remained less likely to receive GA-FSS than women with private insurance.

Early impact of the Patient Protection and Affordable Care Act on insurance among young adults with cancer: Analysis of the dependent insurance provision

BACKGROUND

The Patient Protection and Affordable Care Act (ACA) included provisions to extend dependent health care coverage up to the age of 26 years in 2010. The authors examined the early impact of the ACA (before the implementation of insurance exchanges in 2014) on insurance rates in young adults with cancer, a historically underinsured group.

METHODS

Using National Cancer Institute Surveillance, Epidemiology, and End Results data for 18 cancer registries, the authors examined insurance rates before (pre) (January 2007-September 2010) versus after (post) (October 2010-December 2012) dependent insurance provisions among young adults aged 18 to 29 years when diagnosed with cancer during 2007 through 2012. Using multivariate generalized mixed effect models, the authors conducted difference-in-differences analysis to examine changes in overall and Medicaid insurance after the ACA among young adults who were eligible (those aged 18-25 years) and ineligible (those aged 26-29 years) for policy changes.

RESULTS

Among 39,632 young adult cancer survivors, the authors found an increase in overall insurance rates in those aged 18 to 25 years after the dependent provisions (83.5% for pre-ACA vs 85.4% for post-ACA; P<.01), but not among individuals aged 26 to 29 years (83.4% for pre-ACA vs 82.9% for post-ACA; P = .38). After adjusting for patient sociodemographics and cancer characteristics, the authors found that those aged 18 to 25 years had a 3.1% increase in being insured compared with individuals aged 26 to 29 years (P<.01); however, there were no significant changes noted in Medicaid enrollment (P = .17).

CONCLUSIONS

The findings of the current study identify an increase in insurance rates for young adults aged 18 to 25 years compared with those aged 26 to 29 years (1.9% vs -0.5%) that was not due to increases in Medicaid enrollment, thereby demonstrating a positive impact of the ACA dependent care provisions on insurance rates in this population.

Effect of cost-sharing reductions on preventive service use among Medicare fee-for-service beneficiaries

BACKGROUND

Section 4104 of the Patient Protection and Affordable Care Act (ACA) waives previous cost-sharing requirements for many Medicare-covered preventive services. In 1997, Congress passed similar legislation waiving the deductible only for mammograms and Pap smears. The purpose of this study is to examine the effect of the deductible waiver on mammogram and Pap smear utilization rates.

METHODS

Using 1995-2003 Medicare claims from a sample of female, elderly Medicare fee-for-service beneficiaries, two pre/post analyses were conducted comparing mammogram and Pap smear utilization rates before and after implementation of the deductible waiver. Receipt of screening mammograms and Pap smears served as the outcome measures, and two time measures, representing two post-test observation periods, were used to examine the short- and long-term impacts on utilization.

RESULTS

There was a 20 percent short-term and a 25 percent longer term increase in the probability of having had a mammogram in the four years following the 1997 deductible waiver. Beneficiaries were no more likely to receive a Pap smear following the deductible waiver.

CONCLUSIONS

Elimination of cost sharing may be an effective strategy for increasing preventive service use, but the impact could depend on the characteristics of the procedure, its cost, and the disease and populations it targets. These historical findings suggest that, with implementation of Section 4104, the greatest increases in utilization will be seen for preventive services that screen for diseases with high incidence or prevalence rates that increase with age, that are expensive, and that are performed on a frequent basis.
