Objectives: This study (1) developed and deployed a program to enhance patient knowledge about antibiotic use; (2) evaluated whether providing patient education is associated with improvements in antibiotic knowledge; and (3) explored the association between antibiotic knowledge and health literacy.
Study Design: Using a prospective pretest-posttest study design, educational seminars were provided to groups of community members. Participant sociodemographic characteristics including a measurement of health literacy were collected at baseline. Antibiotic knowledge was collected before and after the educational seminar.
Methods: Participants were required to be ≥18 years old and English -speaking. Participant knowledge of antibiotic use was measured using a 14-item questionnaire. A knowledge index was constructed by summing the correct answers for a range of 0 to 14. Pre- and post-program knowledge were compared using a paired t-test. Participants were offered a $10 gift card after completing the seminar.
Results: For the 19 participants who took both the pre- and post-test, the antibiotic knowledge index significantly increased by 2 points (p=0.0011) after completing the educational seminar. Although the participants’ Newest Vital Sign (NVS) scores were positively correlated to their pre-test antibiotic knowledge scores; this correlation was not significantly different than zero (p=0.22). However, a positive correlation between NVS scores and post-test antibiotic knowledge scores was found to be statistically significant (p=0.0004).
Conclusions: This study demonstrated: (1) patients have limited understanding of bacteria vs. viruses and treatment; (2) educational programs can improve antibiotic use knowledge; and (3) the educational program may be more effective for those with higher literacy levels.
