Insights
Hepatitis C virus (HCV) screening increased slightly in the Military Health System after CDC recommendations for baby boomers. Interventions are needed to boost testing awareness and provider screening.
Area of Science:
- Hepatology
- Public Health
- Epidemiology
Background:
- Chronic hepatitis C virus (HCV) is a prevalent blood-borne infection in the US.
- An estimated 2.7 to 3.9 million Americans were living with HCV in 2014.
- The Centers for Disease Control and Prevention (CDC) issued a universal screening recommendation for baby boomers in August 2012.
Purpose of the Study:
- To determine the proportion of individuals screened for HCV within the US Department of Defense Military Health System.
- To compare HCV screening rates before and after the 2012 CDC recommendation for baby boomers.
- To assess patient and system factors associated with HCV screening.
Main Methods:
- Analysis of a 5% random sample of Military Health System beneficiaries.
- Inclusion of medical claims data from July 2011 to September 2013.
- Comparison of screening rates and associated factors in two periods: pre-recommendation (July 2011-July 2012) and post-recommendation (September 2012-September 2013).
Main Results:
- HCV screening rates were 1.7% before the recommendation and 2.4% after.
- Screening was associated with benefit type (Prime) and care source (direct care) in both periods.
- Male sex and Black race were associated with testing only before the August 2012 recommendation.
Conclusions:
- A modest increase in HCV screening occurred post-recommendation, but rates remain low.
- Enhanced interventions are necessary to increase awareness of national HCV testing guidelines among baby boomers.
- Improved provider knowledge and performance of screening are crucial for increasing HCV detection rates.
Objectives:
Chronic hepatitis C virus (HCV) is the most common blood-borne infection in the United States, with an estimated 2.7 to 3.9 million cases as of 2014. In August 2012, the Centers for Disease Control and Prevention (CDC) recommended 1-time HCV testing of all baby boomers. The objectives of this study were to (1) determine the proportion of people screened for HCV in the US Department of Defense Military Health System before and after the CDC screening recommendation for baby boomers and (2) assess whether certain patient or system factors were associated with screening for HCV before and after August 2012.
Methods:
We used a dataset containing 5% of beneficiaries randomly selected from the Military Health System Data Repository medical claims database for the period July 2011 through September 2013.
Results:
Of 108 223 people eligible for HCV screening during the first period (July 2011 through July 2012), 1812 (1.7%) were screened. Of 109 768 people eligible during the second period (September 2012 through September 2013), 2599 (2.4%) were screened. HCV screening receipt was related to benefit type (Prime before August 2012: adjusted odds ratio [aOR] = 2.16; 95% confidence interval [CI], 1.89-2.46; Prime after August 2012: aOR = 1.93; 95% CI, 1.73-2.16) and care source (direct care before August 2012: aOR = 1.80; 95% CI, 1.57-2.07; direct care after August 2012: aOR = 2.45; 95% CI, 2.18-2.75); male sex (aOR = 1.17; 95% CI, 1.06-1.29) and black race (aOR = 1.20; 95% CI, 1.05-1.37) were associated with HCV testing only before August 2012.
Conclusions:
Interventions should be implemented to increase awareness and knowledge of the current national HCV testing recommendation among baby boomers to seek out testing and health care providers to perform screening.
