Improving access to HCV treatment: external jugular venepuncture can overcome problems with difficult venous access

Many patients requiring antiviral treatment of chronic hepatitis C (HCV) have a background of significant injection drug use (IDU). In a proportion of patients, IDU results in difficulty with blood collection from conventional sites. We audited patients from the Liver Clinics and Drug Health Pharmacotherapy Service of The Royal Prince Alfred Hospital (RPAH) to determine the incidence of difficulty with blood collection. This survey identified the need for an innovative venous access strategy to better manage this group of patients. An external jugular venepuncture (EJV) protocol and education package was developed in collaboration with the Department of Anaesthetics, Gastroenterology and Liver Centre and HCV clinical nurse consultants (CNC). RPAH policy and procedure committee approved the protocol and patient information sheet. Patients with a history of difficulty with blood collection were eligible for the protocol. Patient satisfaction surveys were conducted. The initial survey of patients from the liver clinics and pharmacotherapy service identified that 48 percent had difficulty with blood collection from conventional sites. In the period October 2002 to July 2006, 29 patients (89 percent with history of IDU) were referred for EJV assessment. Major indications for EJV were for blood testing for initiation and monitoring of antiviral therapy and ongoing assessment of HCV infected patients. No adverse events resulted from the procedure. All patients surveyed report high levels of satisfaction with the technique compared to previous venous access attempts. EJV improves access to antiviral therapy and is a safe and effective technique for patients with difficult venous access (DVA). In addition, we have utilised EJV for post-transplant care of patients and used external jugular vein cannulation as vascular access for contrast imaging in hepatocellular carcinoma (HCC) assessment.
