We propose a set of standards to aid the physician in the care of older patients. These standards are based on the practical experiences of our own group and of others with years of clinical practice in geriatric medicine. The standards also reflect the guidelines, position papers, and deliberations of various organizations concerned with the care of older people. This article does not discuss specific illnesses or the common geriatric syndromes. The proposed standards cover comprehensive care and assessment, especially of vulnerable elders and prevention of disease and disability. We also propose standards for facilitation of care across the health service continuum, care of the nursing home resident, and palliative and hospice care.
