Concomitant illness and especially the use of urethral catheters, but not advanced age itself, are associated with a higher mortality from bacteremic urinary tract infection. Single agent empiric antimicrobial therapy such as ceftriaxone may be appropriate in older patients with presumed urosepsis, except in catheterized patients or those with other risk factors for Gram-positive or resistant Gram-negative infections.

The introduction of regular visits to nursing home patients by a physician assistant can reduce hospitalization and medical costs of these frail older people.

Assessment of the relation between life indicators and health outcomes is a complex problem. The authors' analysis uses descriptive canonical correlation, and their solution suggests that socioeconomic factors play a major role in health outcomes. The supply of primary care physicians has a lesser but still important role: canonical correlation suggests no apparent role in enhancing health outcomes among the elderly but a larger role in improving health among the young. The authors' analysis does support the notion that specialist physician supply has no correlation with a wide range of health outcomes.
