Systems medicine and the public's health

Innovative 'systems' approaches to biomedical research offer substantial promise for advancing knowledge and improving health care, as outlined by Bousquet et al. in this issue. However, they are unlikely to improve population health without concurrent efforts to address environmental and social contributors to health, including conditions such as poverty, substandard housing, and restricted access to employment and education. Biomedical researchers have a responsibility to promote realistic expectations for systems or 'P4' medicine, and to join others in calling for broad efforts to promote equitable access to health care and social conditions that promote well-being.
