Demonstrate commitment to using risk-benefit, cost-benefit, and evidence- based consideration in the selection of therapeutic interventions. Demonstrate ongoing commitment to self-directed learning regarding therapeutic interventions. Seek feedback regularly regarding therapeutic decision making and respond appropriately and productively.

Recognize the importance of and demonstrate a commitment to the utilization of other health care professionals in therapeutic decision making. During the internal medicine core clerkship, the student can put into practice some of the ethical principles learned in the preclinical years, especially by participating in discussions of informed consent and advance directives. Additionally, the student learns to recognize ethical dilemmas and respect different perceptions of health, illness, and health care held by patients of various religious and cultural backgrounds. Basic ethical principles (autonomy, beneficence, nonmaleficence, truth- telling, confidentiality, and autonomy). The role of the physician in making decisions about the use of expensive or controversial tests and treatments. Circumstances when it may be unavoidable or acceptable to breach the basic ethical principles.

Recognize the potential conflicts between patient expectations and medically appropriate care. Therefore, they must master and practice self- directed life-long learning, including the ability to access and utilize information systems and resources efficiently. Key sources for obtaining updated information on issues relevant to the medical management of adult patients. Key questions to ask when critically appraising articles on diagnostic tests: • Was there an independent, blind comparison with a reference (“gold”) standard? Key questions to ask when critically appraising articles on medical therapeutics: • Was the assignment of patients to treatments randomized? Performing a computerized literature search to find articles pertinent to a focused clinical question. Summarizing and presenting to colleagues what was learned from consulting the medical literature. Recognize the value and limitations of other health care professionals when confronted with a knowledge gap. Appropriate care by internists includes not only recognition and treatment of disease but also the routine incorporation of the principles of preventive health care into clinical practice. All physicians should be familiar with the principles of preventive health care to ensure their patients receive appropriate preventive services. Criteria for determining whether or not a screening test should be incorporated into the periodic health assessment of adults. General types of preventive health care issues that should be addressed on a routine basis in adult patients (i. Methods for counseling patients about risk-factor modification, including the “stages of change” approach to helping patients change behavior. General categories of high-risk patients in whom routine preventative health care must be modified or enhanced (e. The potential roles and limitations of genetic testing in disease prevention/early detection. Obtaining a patient history, including a detailed family history, vaccination history, travel history, sexual history, and occupational exposures. Counseling patients about safe-sex practices, smoking cessation, alcohol abuse, weight loss, healthy diet, exercise, and seat belt use.
