Work-related and individual factors in biological exposure incidents: A scoping review

Abstract

Background and objective: Biological exposure incidents are frequent in the workplace and have serious repercussions on the health of professionals, with millions of cases annually and thousands of infections by blood-borne viruses. The objective of this study was to map and analyze aspects related to work and individual factors associated with biological exposure incidents involving healthcare professionals in the hospital environment.

Methods: This is a scoping review following the JBI methodology. The guiding question was: “What are the aspects related to work and individual factors associated with biological exposure incidents in the hospital environment?” Searches were conducted in electronic databases including LILACS, BVS, MEDLINE/Pubmed, CINAHL, Embase, Scopus, and Web of Science. Studies from primary care professionals, those without clear methodology, case reports, expert opinions, review studies, and grey literature were excluded. Screening and inclusion were conducted by two reviewers with disagreements resolved by a third reviewer.

Results: A total of 10,365 articles were found; applying a temporal limit of the last 5 years yielded 4,542 articles. After removing duplicates, 1,965 studies remained. Following title and abstract screening, 140 articles were selected. After full-text review, 46 studies were included, of which 10 comprised the final sample. Work-related aspects such as high workload, long hours, and rotating shifts increase healthcare professionals' risk of incidents. Similarly, there is an association between individual factors such as fatigue, stress, and drowsiness and such accidents.

Conclusions: Studies underscore the link between biological exposure incidents and inadequate work conditions and organization, exacerbated by physical and mental factors like fatigue, drowsiness, sleep deprivation, and stress.
