Current smoking and quit-attempts among US adults following Medicaid expansion

The objective of this study was to estimate the influence of the Affordable Care Act (ACA) Medicaid Expansion on current smoking and quit attempts in expanded and non-expanded states. We analyzed data from the Behavioral Risk Factor Surveillance System (BRFSS) between 2003 through 2015 to evaluate changes in current smoking and quit attempts using multivariable logistic regression and generalized estimating equations (GEE), adjusting for socioeconomic factors. Time periods evaluated were: 2003–2009 (pre-expansion) and 2011–2015 (post-expansion), and in supplemental analysis, also 2011–2017. Overall, smoking prevalence among adults in expanded and non-expanded states were 16% and 17% (p < 0.001), respectively, and quit attempt prevalence for expanded and non-expanded states were 56% and 57% (p = 0.05), respectively. In adjusted models comparing post- versus pre- expansion periods, current smoking declined by 6% in both expanded (RR: 0.94, 95% CI: 0.93–0.94) and non-expanded (RR: 0.94, 95% CI: 0.94–0.95) states. Quit attempts increased by 4% (RR: 1.04, 95% CI: 1.04–1.05) in expanded states, and by 3% (RR: 1.03, 95% CI: 1.02–1.03) in non-expanded states. States that imposed barriers to utilization of smoking cessation services e.g. prior authorization, saw only a 3% increase in quit attempts regardless of expansion status, while expanded states that did not impose barriers experienced a 6% (RR: 1.06, 95% CI: 1.05–1.06) increase in quit attempts. Reducing administrative barriers to smoking cessation programs may enhance further declines in smoking rates among US adults.

Disparities in the prevalence of comorbidities among US adults by state Medicaid expansion status

INTRODUCTION

About 92% of US older adults have at least one chronic disease or medical condition and 77% have at least two. Low-income and uninsured adults in particular experience a higher burden of comorbidities, and the Medicaid expansion provision of the Affordable Care Act was designed to improve access to healthcare in this population group. However, a significant number of US states have declined expansion. The purpose of this study is to determine the distribution of low-income and uninsured adults in expanded versus non-expanded states, and evaluate the prevalence of comorbidities in both groups.

METHODS

Data from the 2013 Behavioral Risk Factor Surveillance System (BRFSS) dataset was analyzed, and Medicaid expansion status was assessed from the Center for Medicare and Medicaid Services report on State Medicaid and CHIP Income Eligibility Standards. Next, age adjusted mean number of comorbidities between expanded and non-expanded states was compared, with adjustment for socio-demographic differences.

RESULTS

Expanded states had a higher proportion of adults with income of at least $50,000 per year (39.6% vs. 35.5%, p<0.01) and a lower proportion of individuals with no health insurance coverage (15.2% vs. 20.3%, p<0.01) compared with non-expanded states. Among the uninsured, there was a higher proportion of obese (31.6% vs. 26.9%, p<001), and higher average number of comorbidities (1.62 vs. 1.52, p<0.01) in non-expanded states compared to expanded states. Overall, the prevalence of comorbidities was higher among BRFSS participants in states that did not expand Medicaid compared with those in expanded states.

CONCLUSION

States without Medicaid expansion have a greater proportion of poor, uninsured adults with more chronic diseases and conditions.

Public preferences for colorectal cancer screening tests: a review of conjoint analysis studies

A wide range of screening technologies is available for colorectal cancer screening. There is demand to discover public preferences for these tests on the rationale that tailoring screening to preferences may improve uptake. This review describes a type of study (conjoint analysis) used to assess people's preferences for colorectal cancer screening tests and critically evaluates research quality using a recently published set of guidelines. Most primary studies assessed preferences for colonoscopy and fecal occult blood testing but newer technologies (e.g., capsule endoscopy) have not yet been evaluated. Although studies often adhered to guidelines, there was limited correspondence between stated preferences and actual screening behavior. Future research should investigate how studies can go beyond the guidelines in order to improve this and also explore how test preferences may differ by important population subgroups.
