Biohazard Accidents, Harmful Elements to the Wellness of Healthcare Workers, and Their Risk Factors.

BACKGROUND: For healthcare personnel, biohazard accidents pose a significant risk to their health. These exposures can enable the transmission of pathogens such as Hepatitis B, Hepatitis C, and human immunodeficiency virus (HIV). OBJECTIVE: To indicate and quantify the risk associated with higher threatening situations, such as biohazard accidents on repeated occasions or incorrect notifications to injured healthcare professionals. METHODS: A cross-sectional study was conducted at the Poniente Hospital in Almeria (Spain). In total, 592 participants reported 1062 accidents and their characteristics and notifications were analyzed. RESULTS: It was found that women (OR = 1.29) working in the surgical area (OR = 2.92), those on indefinite contracts (OR = 1.67), and those with high work experience (OR = 1.14) were the main risk factors for multiple biohazard accidents. Concerning the incorrect notification of these accidents, the main risk factors were work performance during the afternoon shift (OR = 1.72) and the fact that the accident was caused by the injured worker himself (OR = 1.53). CONCLUSIONS: This study outlined the main factors that can contribute to healthcare professionals suffering these accidents. As a result, corrective measures must be taken against these risk factors to improve safety for healthcare workers in the future.

Fendrix® Vaccine Effectiveness in Healthcare Workers Who Are Non-Responsive to Engerix B® Vaccination.

Hepatitis B (HBV) is a pathogen virus with transmission mechanisms that include contact with the infected blood or bodily fluids of the infected organism. Nowadays, healthcare workers are one of the most exposed groups to HBV. Conventionally, completing a vaccine series dosage with Engerix B® lowers this risk by providing workers with immunity to the virus. However, through the years, we have encountered nonresponsive health personnel to the Engerix B® vaccine; hence, the Occupational Health Service of Poniente Hospital studied the Fendrix® adjuvanted vaccine as an alternative vaccine to develop immunological responses in healthcare workers who do not respond to vaccination with Engerix B®. In our study, we employed a vaccination schedule with the Fendrix® vaccine, performing serology tests on the cases after the application of each dose. The results obtained showed humoral immunity in 92.3% of the cases, with a remarkable increase in antibody titer after the first doses. These encouraging results support the future inclusion of this vaccine as one possible alternative for the immunization to HBV for healthcare workers nonresponsive to Engerix B®.
