Determinants of disinfectant use among nurses in U.S. healthcare facilities

Abstract

Background Disinfectant use among healthcare workers has been associated with respiratory disorders, especially asthma. We aimed to describe disinfectants used by U.S. nurses, and to investigate qualitative and quantitative differences according to workplace characteristics and region. Methods Disinfectant use was assessed by questionnaire in 8,851 nurses. Hospital characteristics were obtained from the American Hospital Association database. Results Working in a hospital was associated with higher disinfectant use (OR: 2.06 [95%CI: 1.89-2.24]), but lower spray use (0.74 [0.66-0.82]). Nurses working in smaller hospitals (<50 beds vs. ≥200 beds) were more likely to use disinfectants (1.69 [1.23-2.32]) and sprays (1.69 [1.20-2.38]). Spray use was lower in the West than in the Northeast (0.75 [0.58-0.97]). Conclusion Disinfectant use was more common among nurses working in smaller hospitals, possibly because they perform more diverse tasks. Variations in spray use by hospital size and region suggest additional targets for future efforts to prevent occupational asthma.

Staphylococcus aureusextracellular vesicles (EVs): surface-binding antagonists of biofilm formation

“…Although not conclusive, both of these findings help to explain the predominance of S. aureus on different surfaces and are of particular importance within hospital settings where bleach is commonly used as a disinfectant 62-64 .…”

Association of hand and arm disinfection with asthma control in US nurses

“…However, chlorhexidine and povidone iodine are currently the agents the most commonly used for surgical hand/arm antisepsis [7]. Moreover, in a survey of a sample of the hospitals where NHSII nurses work, a chlorhexidine solution was used for surgical hand/arm antisepsis in 7 out of 8 hospitals surveyed [13]. Chlorhexidine is a skin sensitizer [6], and cases of occupational asthma or occupational airway allergy due to chlorhexidine have been reported in nurses [14].…”

Development of a bar code-based exposure assessment method to evaluate occupational exposure to disinfectants and cleaning products: a pilot study

“…Other disinfectants frequently used included hypochlorite bleach and hydrogen peroxide. Consistently, in a large study of US nurses,25 participants working in a hospital reported using mostly alcohol, hypochlorite bleach and quats (41%, 24% and 15%). In the same population, nurses were classified as highly exposed to alcohol, hypochlorite bleach or quats by a JTEM (41%, 34% and 48%) 24.…”
