Knowledge and attitudes of medical and pharmacy students about pharmacogenomics: a systematic review and meta-analysis

Pharmacogenomics (PGx) is rapidly growing branch of molecular genetics with high potentials to influence therapeutics. This review evaluates knowledge and attitudes of medical and pharmacy students about PGx. A literature search was conducted in electronic databases and studies were selected by following precise eligibility criteria. After quality assessment, studies were reviewed systematically, and meta-analyses of proportions were performed to estimate response rates of students. Fifteen studies (5509 students; 69% [95% confidence interval (CI): 60%, 77%] females) were included. Among students, 28% [95%CI: 12, 46] had adequate PGx knowledge; 65% [95%CI: 55, 75] were willing to have PGx test for their own risk assessment; 78% [95%CI: 71, 84] had intention to incorporate PGx in future practice; and 32% [95%CI: 21, 43] were satisfied with current PGx component of curriculum. Age, advanced year of educational program, and more time spent in PGx education were positively associated with PGx knowledge and positive attitudes.
