Hepatitis is an inflammation of the liver with a few main genotypes (A, B, C and E), and Hepatitis C is responsible for the vast majority of liver disease among the US population. Over time, undetected Hepatitis C can severely damage the liver, possibly leading to cirrhosis, liver cancer, or death.
An age group identified as being at high risk for Hepatitis C is the "baby boomer" generation: those born between 1945 and 1965. Individuals born during this period are five times more likely than other adults to be infected with the Hepatitis C virus (HCV) - 75 % of adults with hepatitis C were born within this timeframe, and an estimated 15,000 HCV-associated deaths of this age group will occur each year. In the United States, it is estimated that between 3 and 5 million people have chronic hepatitis C, and most of these people feel fine and do not suspect that they are infected. Most cases are insidious, and often a suspicion may only arise from a routine check preceding a blood donation or a lab test showing elevated liver enzymes done as part of a physical examination.
Barriers to Testing
The CDC highly recommends testing for Hepatitis C for these adults; however, certain barriers associated with this virus may delay or deter testing.
In the years immediately following World War II, the number of surgical procedures greatly expanded nationwide, and the sterilization techniques for common procedures were not as advanced as they are today. As Hepatitis is transmitted via the blood, improper sterilization of equipment was a factor. Before widespread screening of the nation's blood supply began in 1992, the hepatitis C virus could spread via blood transfusions and organ transplant procedures. In the past, doctors had no protocol or screening method to check if a blood supply was virus-free.
Most baby boomers were exposed decades ago and have little or no symptoms, so they do not perceive themselves as being at risk.
When thinking about the transmission of the Hepatitis C virus, a common misunderstanding is that a positive result for someone indicates that they are or were a drug abuser. Many are reluctant to get tested as they feel they would be judged harshly and seen in a negative light, the effects of which can lead to a delay in getting tested and diagnosed, receiving treatment, and having an increased risk of complications and poor quality of life.
Although IV drug use rose to a significant level in the '60s, it is not the only risk factor for contracting Hepatitis C. As outlined above, there are several explanations as to why they may have contracted Hepatitis C not related to the use of recreational drugs. Patients should not fear having a blood test to determine the presence of HCV due to exposure to tainted blood from whatever source. It is certainly not a reflection of a person's behavior.
Recent advances in treatment over the last five years have shown remarkable results in eradicating the virus from the system in almost 95% of those treated and eliminating any further damage to the liver, and limiting spread. Treatment recommendations and evidence-based guidelines for healthcare professionals have been established through a collaboration of the Infectious Diseases Society of America, the American Association for the Study of Liver Diseases, and the International Antiviral Society for HCV management. They are available here.
Nurses can play a key role in educating this population on the health impact of Hepatitis C. Encouraging patients to discuss their concerns with their personal healthcare provider and requesting a lab test is the first step in understanding and managing Hepatitis C. Incorporating this test with other screening protocols as part of an ongoing healthcare management plan for baby boomers is a practical and expedient way to identify new cases. Based on CDC estimates, expansion of testing for baby boomers could identify more than 800,000 cases of HCV and, when connecting those requiring treatment to appropriate care, could save more than 120,000 lives in the ensuing years.
