Rising Trends in Emergency Department Visits Associated With Hepatitis C Virus Infection in the United States, 2006-2014.

OBJECTIVE

Emergency departments (EDs) are critical settings for hepatitis C care in the United States. We assessed trends and characteristics of hepatitis C-associated ED visits during 2006-2014.

METHODS

We used data from the 2006-2014 Nationwide Emergency Department Sample to estimate numbers, rates, and costs of hepatitis C-associated ED visits, defined by either first-listed diagnosis of hepatitis C or all-listed diagnosis of hepatitis C. We assessed trends by demographic characteristics, liver disease severity, and patients' disposition by using joinpoint analysis, and we calculated the average annual percentage change (AAPC) from 2006 to 2014.

RESULTS

During 2006-2014, the rate per 100 000 visits of first-listed and all-listed hepatitis C-associated ED visits increased significantly from 10.1 to 25.4 (AAPC = 13.0%; < .001) and from 484.4 to 631.6 (AAPC = 3.4%; < .001), respectively. Approximately 70% of these visits were made by persons born during 1945-1965 (baby boomers); 30% of visits were made by Medicare beneficiaries and 40% by Medicaid beneficiaries. Significant rate increases were among visits by baby boomers (first-listed: AAPC = 13.8%; all-listed: AAPC = 2.6%), persons born after 1965 (first-listed: AAPC = 14.3%; all-listed: AAPC = 9.2%), Medicare beneficiaries (first-listed: AAPC = 18.0%; all-listed: AAPC = 3.9%), and persons hospitalized after ED visits (first-listed: AAPC = 20.0%; all-listed: AAPC = 2.3%; all < .001). Increasing proportions of compensated cirrhosis were among visits by baby boomers (first-listed: AAPC = 11.5%; all-listed: AAPC = 6.3%). Annual hepatitis C-associated total ED costs increased by 400.0% (first-listed) and 192.0% (all-listed) during 2006-2014.

CONCLUSION

Public health efforts are needed to address the growing burden of hepatitis C care in the ED.
