Can patient education initiatives in primary care increase patient knowledge of appropriate antibiotic use and decrease expectations for unnecessary antibiotic prescriptions?

BACKGROUND Healthcare globally is increasingly threatened by antibiotic resistance. Misunderstanding of the appropriate use of antibiotics is common within the general population, therefore patient education could be a useful tool to employ against antibiotic resistance. Patient satisfaction with healthcare is important, and antibiotic awareness is crucial to avoid disappointment when antibiotic stewardship is practiced. AIM This review aims to identify whether patient education is an effective tool to improve knowledge and awareness of the appropriate use of antibiotics and whether it has an effect on expectations of or prescription rates of antibiotics. METHOD Embase, Medline, Web of Science, PubMed, and Cochrane Library were searched to identify studies examining the impact of various forms of patient education on awareness of appropriate antibiotic use and antibiotic prescription rates. Reference lists of eligible studies were also screened. RESULTS Three hundred and fourteen unique studies were identified, of which 18 were eligible for inclusion. All studies were of good quality. Three studies examined public health campaigns, five examined leaflets, two examined posters, three examined videos, four used mixed interventions and one study examined a presentation. The results were too heterogenous to perform a meta-analysis. CONCLUSION Patient education is an effective tool to increase public knowledge and awareness of the appropriate use of antibiotics, and can reduce the expectation of or prescription rates of antibiotics. The form of patient education matters, as interventions involving active learning and engagement demonstrate significant positive outcomes, whereas passive forms of learning do not appear to have any effect on understanding or prescriptions.
