CDC Screening Recommendation for Baby Boomers and Hepatitis C Virus Testing in the US Military Health System

Evaluating the Impact of an Educational Intervention on Hepatitis C Screening in a Midwest Regional Psychiatric Unit

INTRODUCTION

Affecting more than 3.9 million Americans, the hepatitis C virus (HCV) attacks the liver by causing inflammation. Left untreated, HCV can lead to serious consequences. Targeting high-risk individuals in the inpatient psychiatric setting can lead to increased testing and referral.

AIMS

This quality improvement project determined whether an intervention-consisting of a pretest, educational session, posttest, and screening implementation-increased staff knowledge about HCV screening recommendations, identified at-risk individuals, and increased the number of patients screened and referred for treatment.

METHOD

An online HCV educational session was provided to 30 staff at a Midwest regional psychiatric unit. An online pre/posttest was conducted to determine staff knowledge and understanding prior to and after the educational session. An HCV screening tool checklist was incorporated into the electronic health record (EHR) system. A 3-month pre/post-intervention chart review was completed to determine the number of patients identified and screened for HCV.

RESULTS

A comparison of the 30 staff members' mean pre/posttest scores were calculated using an unpaired t test, showing a prescore mean of 55.15 ± 19.09 and a postscore mean of 85.75 ± 13.44, p < .001. A chi-square analysis indicated that there was a statistically significant post-intervention increase in the percentage of high-risk patients identified (5.6%-36.4%, p < .001) and screened (5.6%-31.4%, p < .001) for HCV compared with pre-intervention.

CONCLUSION

The study intervention increased staff knowledge of HCV guidelines and the number of at-risk patients identified and screened for the disease.

Universal HCV Screening of Baby Boomers is Feasible, but It is Difficult

BACKGROUND/OBJECTIVE

Our objective was to assess the impact of mass mailing and the inclusion of Best Practice Advisory (BPA) "Pop-Up" tool in the electronic medical record (EMR) on HCV screening rates.

METHODS

Between June 2015 and March 2020, two interventions were developed for primary care physicians (PCP). An educational letter along with a blood requisition form, signed on behalf of the PCPs, was sent to patients. We also developed a BPA "Pop-Up" screening tool to alert PCPs to order HCV screening tests on patients with no previous screening. Data were collected and analyzed prospectively.

RESULTS

When we started the screening program in June 2015, 33,736 baby boomers were eligible for screening, and the hospital system added an additional 26,027 baby boomers between June 2015 and March 2020. Of the 89 primary care providers employed by the hospital, 75 agreed to participate at different time periods. We screened 23,291 (43.5%) of 53,526 eligible patients during study period. Of these, 399 (1.7%) had HCV antibody, but HCV RNA was positive in only 195 (1%). HCV antibody positivity rates were higher in men, blacks, and in 1951-1960 birth cohorts. Spontaneous clearance rates appeared to be lower in men (OR 0.59, 95% CI 0.39-0.90, P = 0.015) and in blacks (OR 0.31, 95% CI 0.20-0.50, P < 0.001).

CONCLUSION

Although a formal screening program increased screening rates for HCV among baby boomers, about 50% of baby boomers remained unscreened. In this community screening program, we found that men and blacks are less likely to have spontaneous HCV clearance.

Update on Hepatitis C Epidemiology: Unaware and Untreated Infected Population Could Be the Key to Elimination

Globally, the World Health Organization (WHO) estimates that 71 million people have chronic hepatitis C virus (HCV) infection. A significant number of these will develop cirrhosis or liver cancer. Currently, during the COVID-19 outbreak, a high mortality rate has been found in patients with COVID-19 and cirrhosis. New direct-acting antiviral agents can cure more than 90% of HCV-infected patients. The new WHO strategy has introduced global goals against viral hepatitis, including a 30% reduction in new HCV cases and a 10% reduction in mortality by 2020. HCV transmission has changed considerably, reflecting both the evolution of medicine and health and social changes. The HCV is usually spread through blood-to-blood contact. After the discovery of HCV in 1989, antibody screening has drastically decreased the incidence of post-transfusion hepatitis. Nowadays, routine blood donor screening by nucleic acid amplification testing for the presence of HCV RNA has been introduced in many countries. It is conceivable that HCV screening could be offered to people born between 1946 and 1964 in the developed world and to people at high risk for HCV infection such as those who have received blood transfusions, blood products or organ donations before the 1990s, prisoners, health care workers, drug users and infants born to HCV-infected women. To achieve HCV elimination, health programmes should include improvement to access to health care services, increased screening and new projects to identify a submerged portion of patients with HCV infection. Submerged people with HCV infection are both people who are unaware of their condition and people diagnosed with HCV but not yet treated. Based on these premises, this review will examine and discuss the epidemiological changes in contracting HCV, highlighting the ways in which to identify a submerged portion of patients with HCV infection.

Population-based screening of hepatitis C virus in the United States

PURPOSE OF REVIEW

This review summarized the recent evidence on the performance of population-based hepatitis C virus (HCV) screening, published and indexed to PubMed, in the Unite States during the 2-year window from 1 January 2017 to 31 December 2018.

RECENT FINDINGS

A majority of the selected articles in this review focused on the birth cohort 1945-1965 because of the HCV screening recommendations released after August 2012. However, the articles for the high-risk population applied to all ages because the recommendations for this specific population have remained largely unchanged since 1998. The reported rates of HCV screening varied substantially not only across the three different populations (i.e. general, underserved, and high-risk) but also within each population.

SUMMARY

More vigilant monitoring of HCV screening performance of younger birth cohorts is needed as these individuals have been experiencing a higher incidence of HCV infection than those in the birth cohort 1945-1965. In addition, to meet the goal of eliminating HCV infection as a US public health problem by 2030, significant improvement in more accurately and comprehensively reporting the trends in population-based HCV screening across different populations is warranted in the future.
