In this issue of Clinical Infectious Diseases, Naggie et al discuss clinical decision making and present the results of a decision analysis examining the cost of hepatitis C virus (HCV) postexposure prophylaxis (PEP) among healthcare workers who experience a needlestick exposure to HCV-positive body fluids.
The authors discuss that, in an era when we can cure essentially all HCV infections, there are only 3 motivations for PEP. First, it may make sense to use PEP to prevent infections if doing so would decrease HCV transmission during the period of active HCV viremia.
The paper succinctly reviews the evidence and quickly makes clear that among healthcare workers in the United States with a known HCV exposure, basic universal precautions reduce the risk of forward transmission to essentially zero.
A second motivation might be cost. Given that HCV medications are expensive, a shorter course PEP may be cost saving compared with full treatment for HCV infection. To address the possible economic rationale for PEP, the authors developed a decision tree to estimate the costs of PEP for HCV in a hypothetical cohort of 100 healthcare workers who had suffered a needlestick injury.
They used the model to compare the outcomes with PEP to those with a strategy of “no PEP and treat only patients who develop chronic HCV infection.”
A few notable assumptions were made—namely, that PEP was 100% effective at preventing infection, while treatment for chronic HCV was only 98% effective with the first line of therapy.
In addition, individuals who failed first-line treatment for chronic HCV infection were retreated with 100% . . .
