A new study, “Residence in a Medicaid-expansion state and receipt of alcohol screening and brief counseling by adults with lower incomes: Is increased access to primary care enough?” published in Alcohol: Clinical and Experimental Research, found that people living in U.S. states with expanded Medicaid access are more likely to receive alcohol screening during primary care checkups than people living in states that did not expand Medicaid access. The study also revealed the need for improvements in alcohol screenings for patients who do receive Medicaid – for example, comprehensive, evidence-based screenings or brief counseling.

Led by Aryn Phillips, PhD, an assistant professor at the University of Maryland’s School of Public Health and former predoctoral fellow at the Alcohol Research Group (ARG), a program of the Public Health Institute, the study is the first to examine whether the likelihood of receiving alcohol screening and brief counseling among nonelderly low-income adults is associated with living in states that expanded Medicaid eligibility under the Affordable Care Act. Study co-authors included Kate Karriker-Jaffe, PhD, at RTI International and other researchers.

The research team reviewed data from almost 16,000 low-income adults aged 18 to 64 living in 14 states that expanded Medicaid eligibility before 2017 and nine states that did not. The study found no significant associations between living in Medicaid expansion states and receipt of evidence-based interventions for alcohol misuse.

Findings suggest that expanded Medicaid access may increase screening rates through increased access to primary care. They also highlight the need for policies and programs that limit healthcare provider constraints and support healthcare providers in offering evidence-based screenings and counseling of alcohol use on a consistent basis.

Study researchers noted that the rates of receiving screening and counseling across this low-income sample were low. Only 60 percent of respondents were asked whether they drink and, of those who reported drinking within the last month, only half were asked how much they drank and a third were asked about binge drinking. Of people who reported drinking heavily, less than a third had been offered advice about risky drinking, and less than 20 percent received guidance on how to reduce or quit drinking.

The authors suggest that healthcare provider and system barriers, such as limited training, lack of tools for screening and referral, and time constraints, may be responsible for the low rates of screening and counseling.

“This research suggests that expanding access to medical care was key but it’s not enough.  It is critical that we address these barriers to care to ensure that people who may be at risk for alcohol-related health problems are identified and receive appropriate and effective support,” said Phillips.
