Hepatitis C

Background Hepatitis C (HCV) is now recognised as a serious public health problem world-wide and the World Health Organisation estimates that around 170 million people are chronically infected with the virus (WHO, 2003). Estimates vary from between 200,000 to 500,000 people infected with HCV in England and Wales. There is also variation in prevalence between groups; for example, 0.4% in women attending antenatal clinics in inner London, and up to 50% in intravenous drug users (National Institute for Clinical Excellence 2006). HCV is a blood-borne virus with infection occurring through the transfer of body fluids. Intravenous drug users are more at risk of contracting the virus through the sharing of needles (Hope VD, et al. 2001). Health care workers are also at risk from 1exposure prone procedures and through occupational injuries such as needle stick injuries. In 2004, 1624 hepatitis C infections were confirmed in Scotland with 851 new cases between during January and June of 2005; 8240 cases of hepatitis infections were reported in England and Wales, and 100 in Northern Ireland. Given that most hepatitis C infections are asymptomatic, reports of new infections reflect increase in testing patterns rather than trends in incidence. (Advisory Group on Hepatitis, 2005). Some people infected with the HCV may clear the virus in the acute stages of the infection. However, most people infected with HCV are unaware that they carry the virus as they remain well and may only develop symptoms of chronic liver disease many years after the initial infection. There is no known available vaccine to prevent transmission of HCV, however, the National Institute of Clinical Excellence (NICE) has recommended a combination of treatment for moderate to chronic hepatitis C, There is no routine testing UK for detecting HCV in asymptomatic pregnant women. Mother to child transmission (vertical transmission) is known to occur but is less common and estimated to be around 6% and higher if there is parallel infection such as with the HIV virus.

Exposure prone procedures are those where there is a risk that injury to the health care worker could result in their blood contaminating a patient's open tissues.

In addition, no significant association has been found between modes of delivery. Studies that have evaluated breastfeeding in infants born to HCVinfected women, suggest an average rate of infection of 4% in both breastfed and bottle-fed infants (Bhola K, Mcguire W, 2007, www.cdc.gov/hepatitis) Health care workers who carry out exposure prone procedures and are aware that they are HCV positive but refuse to be tested, should not be permitted to carry out exposure prone procedures. However, those who are HCV positive have received treatment and remain negative for six months after treatment, can resume exposure prone procedures (HSC2002/010). The UK Departments of Health also recommend that all occupational exposure to blood or body fluids be followed up with the offer of appropriate testing if there is a risk that the patient is a carrier of hepatitis C infection (HSC 1998/063, Ramsay M, 1999). The Nursing and Midwifery Council (NMC) advises registrants of their legal and professional duty to protect the health and safety of their patients by seeking confidential advice if they believe that they have been exposed to, or at risk of HCV rather than self-asses the risk they may pose to others (NMC, 2006). RCM Position The RCM supports specific antenatal testing for hepatitis C (HCV) for pregnant women and their babies appropriate to their individual risks. Testing must be undertaken with the woman’s explicit informed consent after detailed discussions of the implications of HCV for mother and baby and treatment options. This should be supported with clear and concise written information in a format that the woman can understand. While testing for HCV may be in the interest of the woman and her baby, the RCM respects a woman’s right to decline testing. The RCM urges employers to maintain the confidentiality of HCV infected health care workers. RCM recommends that: Women infected with HCV should be appropriately referred for discussion on investigations, treatment options, and the implications for themselves, their sexual partners and family. Where possible, this discussion and any written information should be available in the mother’s first language. Midwives offer women specialist advice and counselling services appropriate to the woman’s individual needs. Midwives support women who have chosen to breast feed as breastfeeding is not contraindicated in HCV infected women. Midwives assure confidentiality of clients’ who are HCV positive and disclose information only on a need to know basis and with the woman’s consent

Midwives adhere to universal precautions in order to minimise the risk of occupational exposure to HCV. Midwives familiarize themselves with UK departments of health policies and guidance relating to exposure prone procedures and HCV infected health care workers. Midwives contact their RCM representative in situations where they perceive an employment relations issue arising as a result of testing or treatment for HCV. Prospective midwifery students who are HCV positive declare their status before commencing training. Midwives seek medical advice and consider testing if they are aware that they may be at risk of HCV infection. Employers provide midwives with full and clear information on the risks of occupationally acquired hepatitis C infection, long-term implications and treatment options.
