Background Infectious agents, such as bloodborne viruses (BBVs), can potentially be transmitted from healthcare workers (HCWs) to patients. In an effort to reduce this risk to patients, this guideline, which provides a framework for policies on the management of HCWs infected with BBVs in Canada, was developed. Methods A total of six systematic reviews (1995–2016) were conducted to inform the risk of transmission of human immunodeficiency virus (HIV), hepatitis C virus (HCV), and hepatitis B virus (HBV) from infected HCWs to patients and the infectivity of each virus related to source serum viral load. Three environmental scans were conducted to inform sections on disclosure of HCW's serologic status, Expert Review Panels, and lookback investigations. Government partners and key stakeholder organizations were consulted and a Task Group provided technical expertise. Results The risk of HCW-to-patient BBV transmission is negligible, except during exposure-prone procedures where there is a risk of HCW injury and possible exposure of a patient's open tissues to the HCW's blood. Transmission rates were lowest with HIV and highest with HBV (Table 1). Rates varied with several factors including source viral load, nature of potential exposure, infection prevention and control breaches, susceptibility of exposed patient, and use of post-exposure prophylaxis where relevant. The extent of reporting bias for exposure incidents where transmission did not occur is unknown. Current antiviral therapy informed guideline recommendations, with viral load thresholds provided to assist treating physician, Expert Review Panels and regulatory authorities in determining a HCW's fitness for practice. Conclusion Routine Practices (or Standard Precautions) are critical to prevent HCW-to-patient transmission of infections; including BBVs. Recommendations provided in this guideline aim to further reduce the already minimal risk of HCW-to-patient transmission. The guideline provides a pan-Canadian approach for managing HCWs infected with a BBV, with recommendations directly impacting clinical practice related to preventing and controlling healthcare-associated infections.
