Assessing Knowledge and Awareness of Nitrate Contamination: A Survey of Healthcare Professionals

Our study assessed the knowledge, attitudes, and confidence of healthcare professionals (HCPs) about nitrate contamination of drinking water and adverse health outcomes. A cross-sectional survey was administered ( n = 689). Descriptive statistics, nonparametric tests, and linear regression were used to compare means in behavior and examine the effect of knowledge and attitudes on information-sharing practices with patients. Qualitative analysis of open-ended questions identified gaps in knowledge, current access to resources, and preferences for future training and resources. Participants reported a lack of knowledge about the detrimental health effects of nitrates and low confidence in advising their patients about drinking water quality. Participant attitude was a strong and significant predictor of information-sharing behaviors ( B = 0.624, p < .001). Participants also reported a need for additional knowledge and resources via educational videos, virtual training, and websites. Future research should develop targeted interventions to provide education and training for HCPs about nitrate contamination and its effect on adverse health outcomes.
