Abstract Occupational exposure to disinfecting and cleaning agents is common and high in hospitals. The aim of the study was to determine whether self-reported occupational exposure various cleaning and disinfecting agents among hospital workers is accurate, in comparison to expert assessment. Hospital workers were interviewed by questionnaire regarding tasks and use of cleaning and disinfecting agents. The expert assessment involved a standardised procedure to estimate intensity, frequency and probability of exposure for each job. The analysis focused on eight exposures: formaldehyde, glutaraldehyde, bleach, alcohol, quaternary ammonium compounds, ammonia, sprays and latex gloves. Agreement and differences between self-reported and expert estimates were subjected to statistical analysis. Underestimations of self-reported exposures compared to expert assessments were observed especially for formaldehyde (26.5% vs 32.7%), ammonia (7.4% vs 18.8%), alcohol (64.9% vs 93.0%) and quaternary ammonium compounds (16.6% vs 70.9%). A large underestimation of self-reported exposure and a lack of knowledge of product components were observed. Findings show the relevance of expert assessment in epidemiological studies to limit measurement bias. This work underlines the need for health education programmes on the occupational risks induced by these types of products.
