Four in ten hepatitis C patients who drank alcohol refrained from it as part of a Duke pilot program that integrates alcohol and hepatitis C treatments. Led by DGHI researcher Rae Jean Proeschold-Bell and Duke physician Andrew Muir, the dual model of care may be a viable option for steering these patients away from alcohol, who may otherwise develop serious health complications that lead to liver failure or death.
The Duke study, featured in the April issue of Digestive Diseases and Sciences, involved hepatitis C patients from the Duke Liver Clinic who received both alcohol treatment and medical care over a six-month period. Of the 53 alcohol-drinking patients in the study, 44 percent had stopped drinking alcohol by the end of the six months. Patients who did not become abstinent by six months still reported a 30 percent drop in alcohol consumption, spending on alcohol and urges to drink.
“We were able to show that integrated hepatitis C-alcohol care is feasible,” said Proeschold-Bell, a DGHI faculty member at the Center for Health Policy and Inequalities Research. “More than that, the study shows that such integrated care results in alcohol reductions that benefit patient health.”
Researchers say the intervention worked in part because it focused on liver health, rather than simply reducing alcohol use. It involved weekly group therapy and bi-weekly individual sessions customized to each patient that address alcohol use, nutrition, stress and family support. Because knowledge alone does not change behavior, the addictions specialist taught patients practical ways to improve other aspects of their lives based on their individual circumstances. Study participants were also evaluated for mental illness and had access to a psychiatrist for care, if needed.
The research team also found ways to increase communication and collaboration between the patient’s hepatologist and addictions specialist, a critical part of the study.
“We didn’t know the extent to which we could get busy medical providers and addictions specialists to collaborate. We had to find ways to fit the collaboration into the clinic flow,” said Proeschold-Bell. “In some instances, we had the addictions specialist use a laptop outside the patient exam rooms so medical providers could easily access her and her knowledge about the patient’s alcohol use and behavior changes.”
To date, studies have shown that adults with hepatitis C are three times more likely to have at least one alcoholic drink a day and almost eight times more likely to have at least three drinks a day, compared to adults without hepatitis C. The combination of alcohol use and hepatitis C speeds the time to liver failure and increases rates of liver fibrosis and cancer.
As strong proponents of clinic-based alcohol treatment, Proeschold-Bell and Muir hope to pursue a larger study that recruits patients from the Duke Liver Clinic, the UNC Liver Clinic and the Durham Veterans Affairs Medical Center.
“Alcohol treatment needs to occur in a trusted and known setting,” said Muir. “This study shows that patients will attend alcohol treatment offered in the liver clinic setting and try to change their behaviors in the context of their lives beyond alcohol use.”
