Previous studies have asserted that anesthesia providers are deficient in their knowledge of herbal supplements and their perioperative interactions. The purpose of this project was to examine the impact of an educational handout on Certified Registered Nurse Anesthetists’ (CRNAs) knowledge and attitudes of herbal supplements and their perioperative interactions utilizing a pre-posttest project design. The survey components were sent to approximately 1,600 members of the Illinois Association of Nurse Anesthetists (IANA) with a response of 140 surveys. Data was analyzed using descriptive Cohen’s d and nonparametric statistical tests. Reliability of the instruments used were assessed using Cronbach’s ɑ coefficients. The posttest Cronbach’s ɑ coefficient for attitudes subscale was 0.817, and for the knowledge subscale was 0.915, both of which indicate a high reliability of the consistency of the items in the attitude and knowledge subscale. The Cohen’s d values for attitudes and knowledge were -0.89 and -0.11 respectively. Thus, the tool had a large effect on attitudes and a small effect on knowledge. The p values for attitudes (p = 0.000) and knowledge (p = 0.043) were both statistically significant. There were no statistically significant differences found in the mean scores for attitude or knowledge based on categorical groupings by gender, level of education, years of practice, or age.
