The acceptable duration between occupational exposure to hepatitis B virus and hepatitis B immunoglobulin injection: Results from a Korean nationwide, multicenter study

Occupational exposure to Hepatitis B virus, disease burden and pathways for postexposure prophylaxis management: recommendations for healthcare workers in highly endemic settings

Hepatitis B Virus (HBV) was recognized many decades ago as an important occupational hazard for Health Care Workers (HCWs) globally. HCWs who are directly involved in patient care and are in continuous contact with blood or body fluids have an increased risk of occupationally acquiring the virus. The risk of HCWs in highly endemic areas is greater due to the greater prevalence of infection in the general population. Recommendations are available to guide HBV prevention activities or practices among HCWs. These include the use of the hepatitis B vaccine as a preexposure prophylaxis and the use of hepatitis B immunoglobulin alone or hepatitis B immunoglobulin plus the vaccine as postexposure prophylaxis. The uptake of preexposure prophylaxis has been observed to be low in resource-poor settings where the disease is highly endemic. Postexposure prophylaxis has become the remedy for preventing occupational transmission of HBV in these settings. This review aimed to summarize the available evidence on the risk of transmission of HBV infection, the burden of infection and recommendations for pre- and postexposure prophylaxis for the prevention of occupational acquisition of HBV among HCWs. We conducted a narrative review to summarize the evidence available on the recommended steps of HBV exposure management and the utilization of post-exposure prophylaxis (PEP) for HBV. A comprehensive search was conducted in PubMed, Science Direct, Google Scholar, and Africa Journals Online (AJOL) databases. The keywords used were hepatitis B, hepatitis B virus postexposure prophylaxis, occupational exposures, and recommendations for postexposure to hepatitis B virus. We gleaned evidence from the literature sources and summarized the concepts related to exposure forms, postexposure prophylaxis management pathways and recommendations for the utilization of postexposure prophylaxis among exposed healthcare workers. From the synthesis of evidence, we conclude that HBV infection is a life-threatening condition. However, the disease is preventable by using the HBV vaccine as a preexposure prophylaxis measure. An effective postexposure prophylaxis management program is also available, and the last resort to preventing occupational transmission of HBV among HCWs who non-responders are, or who fail to vaccinate completely against HBV. Irrespective of the availability of these lifesaving interventions, the use of pre- and post-exposure prophylaxis among HCWs in highly endemic regions is suboptimal. Many barriers operating at the individual HCW and health facility levels have been identified as impacting the successful use of HBV preventive measures.

Post-vaccination anti-HBs testing among healthcare workers: More economical than post-exposure management for Hepatitis B

OBJECTIVE

to compare the direct cost, from the perspective of the Unified Health System, of assessing the post-vaccination serological status with post-exposure management for hepatitis B among health care workers exposed to biological material.

METHOD

cross-sectional study and cost-related, based on accident data recorded in the System of Information on Disease Notification between 2006 and 2016, where three post-exposure and one pre-exposure management scenarios were evaluated: A) accidents among vaccinated workers with positive and negative serological status tests for hepatitis B, exposed to known and unknown source-person; B) handling unvaccinated workers exposed to a known and unknown source-person; C) managing vaccinated workers and unknown serological status for hepatitis B and D) cost of the pre-exposure post-vaccination test. Accidents were assessed and the direct cost was calculated using the decision tree model.

RESULTS

scenarios where workers did not have protective titles after vaccination or were unaware of the serological status and were exposed to a positive or unknown source-person for hepatitis B.

CONCLUSION

the direct cost of hepatitis B prophylaxis, including confirmation of serological status after vaccination would be more economical for the health system.

Pattern and serological profile of healthcare workers with needle-stick and sharp injuries: A retrospective analysis

Background:

Needle-stick and sharp injuries (NSSIs) are very hazardous to healthcare workers (HCWs) working in any healthcare setting. The burden of NSSIs is more common in developing countries than in developed countries.

Materials and Methods:

A retrospective analysis was conducted in a multispeciality, tertiary level teaching medical institute. Total 78 NSSIs incidences from 2005 to 2013 were reviewed and included for the study. All the information were retrieved and entered in excel sheet for data analysis.

Results:

Total of 78 NSSIs cases were reported over a period of 9 years. Maximum incidences of NSSI were reported by nurses (61.5%). A higher proportion (41%) of cases occurred in critical units and emergency and the most common procedure (64.1%) was parenteral medication during which HCWs got NSSIs. Almost half (53.8%) of HCWs had received complete HBV vaccination. Out of 78, 40 HCWs only completed follow-up for 6 months and were found non-reactive for viral markers.

Conclusion:

The healthcare workers who were involved in patient care are at risk to get NSSIs. The primary prevention of NSSIs is very important. Every institute should have policies on ongoing training programme, HBV vaccination protocol, smooth system of NSSIs reporting, post-exposure prophylaxis (PEP) facilities and follow-up of HCWs with NSSIs to prevent the occurrence.
