Contamination: concept analysis and nursing implications.
OBJECTIVE
To analyze the concept of contamination and discuss the implications for nursing practice, research, and education.


METHODS
Published research articles, official governmental publications, policy reports, and textbooks.


RESULTS
Various attributes of contamination are described using the Walker and Avant method of concept analysis and include: (a) exposure to a contaminant, and (b) contaminant exists in a dose sufficient to cause adverse health effects. The major antecedents of contamination include the presence of a contaminant, dose, duration of exposure, route of exposure, and individual human differences. Major consequences of contamination include organ and systemic responses, and psychological, social, and economic effects.


CONCLUSIONS
Contamination is an important concept and is essential to the discipline of nursing. The concept of contamination is separate from exposure. Precision in the use of diagnostic language describing contamination incidents will lead to greater accuracy in outcomes and interventions for individuals and groups experiencing overt or covert contamination resulting from accidental or intentional acts. Broad agreement on the definition, antecedents, and consequences of contamination will improve the likelihood of successful management of contamination events.


CONCLUSIONS
The nursing profession makes an important contribution to the improvement of individual, community, and societal environmental health. Clarifying the concept of contamination is an important first step in building the nursing science that will lead to identifying sound nursing interventions.
