Abstract
PARRA-TAPIA, Elena; PERALES-ORTIZ, Guillermo; QUEZADA, Amado D and TORRES-PEREDA, Pilar. Occupational health and safety: educational intervention for cleaning workers in research sectors. Salud pública Méx [online]. 2019, vol.61, n.5, pp.657-669. Epub Aug 07, 2020. ISSN 0036-3634. https://doi.org/10.21149/10026.
Objective:
To evaluate the results of educational intervention on health and safety regarding principles of biosafety in cleaning workers of a health institution.
Materials and methods:
Using concurrent mixed methods, we evaluated a total of 31 workers on their knowledge, attitudes, and practices of biosafety and risk perception. We conducted baseline measurements and two follow-ups. Fractional logistic regression models were fitted with study stage as covariate. Additional models included interactions of study stage with key workers characteristics. Thematic qualitative analysis and triangulation was developed.
Results:
The knowledge (+33.3 points, scale 0-100), attitudes (+10.6), and practices (+23.5) increased significantly in the first follow-up; knowledge decreased in the second follow-up (p<0.001). The qualitative findings revealed an improvement in risk prevention attitudes and practices, framed by experiences of vulnerability, stigma, and discrimination.
Conclusions:
The study provides key elements for biosafety research related to vulnerable groups and it is effective in promoting the health of a disadvantaged and invisible sector.
