[Pharmacogenetics in future medical care -- implications for patients and physicians]

Since public acceptance of pharmacogenetic testing will largely influence their implementation in routine medical care, common implications of pharmacogenetic testing from patients', physicians' and scientists' perspective are reviewed.

Broad literature review (MEDLINE; MeSH terms: Pharmacogenetics, Delivery of Health Care, Ethics, Attitude, Patient Acceptance of Health Care) of empirical and theoretical studies describing psychological, family-related, social, and ethical consequences of pharmacogenetic testing to describe relevant aspects for further empirical studies.

Apart from anticipated benefit, acceptance of pharmacogenetic testing might be influenced by the following: Expectation of negative psychosocial consequences, fear of discrimination or violation of privacy. Due to its great complexity, understanding of test results and explanation of their impact pose new challenges for physician-patient relations. Since most studies are conceptual, empirical studies exploring attitudes of patients/physicians and determining medical as well as economic value of pharmacogenetic testing are imperative.
