A hepatitis C awareness initiative dramatically raised the rate of HCV screening and treatment in a large American Indian population – the ethnic group with the highest rate of HCV infection and HCV-related mortality in the United States, according to a report published May 13 in Morbidity and Mortality Weekly Report.
Cherokee Nation Health Services undertook the effort in 2012 to improve detection and management of HCV. It included a reminder in eligible patients’ electronic health records (EHRs) to offer screening; HCV education for primary care physicians and other health care providers; establishment of an HCV registry to monitor the clinical care of patients who initiated antiviral treatment; and outreach efforts by public health nurses to HCV patients, including home visits.

In 2014, an additional initiative was implemented to expand services for the rapidly increasing number of patients diagnosed as having HCV. This allowed a transition from having a single clinic staffed by only one caregiver with expertise in HCV management to five clinics staffed by three physicians, two nurse practitioners, and two pharmacists with HCV expertise, said Dr. Jorge Mera, director of infectious diseases, Cherokee Nation Health Services, Tulsa, Okla., and his associates.
An analysis of deidentified data in the HCV registry and EHRs showed that 92,012 patients aged 20 years and older had at least one visit with Cherokee Nation Health Services after the program was implemented, between October 2012 and July 2015. The proportion of this patient population that was tested for HCV antibodies rose fivefold, from 3.6% to 18.2% during the study period. A total of 715 patients were antibody positive, and 388 of them were found to have chronic HCV infection. Approximately 60% of these patients initiated antiviral treatment, and approximately 90% of them achieved a sustained virologic response and were essentially cured, Dr. Mera and his associates said (MMWR. 2016 May 13;65[18]:461-6).
The program included a component that particularly targeted baby boomers – patients born between 1945 and 1965 – for HCV screening. Across the Indian Health Service clinics in 34 states that adopted this component of the program, such screening increased fourfold in this high-risk population during the study period (MMWR. 2016 May 13;65[18]:467-9).
These efforts, the first of their kind in the United States, may help eliminate hepatitis C as a health disparity for American Indian/Alaska Native populations and also may serve as a model for other health care settings, the investigators added.
