Pharmacogenomics is a growing field of science that explores the genetic contributions in an individual's response to the drug, so as to choose the right drug in the right doses tailored to a patient's genetic makeup. Although pharmacogenomics information is incorporated in chapters discussing relevant drugs, it has not been materialized into clinical practice yet and still, it remains a challenge due to limited knowledge and accessibility of the pharmacogenomic tests to diagnose these polymorphisms. With this background, the objective of the study was to assess the knowledge and perception of pharmacogenomics among second-year MBBS students and to sensitize them regarding pharmacogenomics.
A cross-sectional study was done in which 138 medical students responded to a preformed semi-structured assessment tool. It comprised two main components (1) knowledge and (2) relevance of pharmacogenomics in medical education and clinical practice.
Ninety-five percent students defined pharmacogenomics correctly, but only 54% were aware of genetic variations in drug targets, metabolizing enzymes, and transporters affecting drug therapy. Only 15% knew about the availability of pharmacogenomics tests in India. Eighty-four percent of students felt that incorporating pharmacogenomics education in the MBBS curriculum is a must for precision medicine.
Second-year MBBS students had good knowledge of pharmacogenomics, but knowledge about the application in clinical practice and interpretation of pharmacogenomics was limited. Therefore, we recommend (1) basic pharmacogenomic education at all levels of medical curricula, (2) development of case-based knowledge application modules, (3) regular continuing medical education to update about available screening tools/biomarkers, and (4) patient and public awareness programs so that they receive personalized/precision medicine with optimum efficacy and reduced side effects and health-care costs.
药物基因组学是一个不断发展的科学领域,它探索个体对药物反应的遗传贡献,以便根据患者的基因构成选择正确的药物和正确的剂量。虽然药物基因组学信息已纳入讨论相关药物的章节中,但尚未在临床实践中得到体现,由于对诊断这些多态性的药物基因组学检测的了解和可及性有限,这仍然是一个挑战。在此背景下,本研究的目的是评估二年级医学生对药物基因组学的知识和看法,并使他们对药物基因组学敏感。
我们进行了一项横断面研究,共有 138 名医学生对预先制定的半结构式评估工具做出了回应。它由两个主要部分组成:(1)知识;(2)药物基因组学在医学教育和临床实践中的相关性。
95%的学生正确定义了药物基因组学,但只有 54%的学生知道药物靶点、代谢酶和转运体的遗传变异会影响药物治疗。只有 15%的学生知道印度有药物基因组学检测。84%的学生认为在 MBBS 课程中纳入药物基因组学教育对于精准医学是必须的。
二年级医学生对药物基因组学有很好的了解,但对其在临床实践中的应用和药物基因组学的解释知之甚少。因此,我们建议:(1)在医学课程的各个层次都开展基础药物基因组学教育;(2)开发基于案例的知识应用模块;(3)定期开展继续教育以更新可用的筛查工具/生物标志物;(4)开展患者和公众意识项目,使他们接受个性化/精准医学治疗,以提高疗效,减少副作用和医疗保健费用。
