Evaluating the cost-effectiveness of fall prevention programs that reduce fall-related hip fractures in older adults.

Objectives: To model the incremental cost-utility of seven interventions reported as effective for preventing falls in older adults.

Design: Mathematical epidemiological model populated by data based on direct clinical experience and a critical review of the literature.

Setting: Model represents population level interventions.

Effects of aerobic exercise training in community-based subjects aged 80 and older: a pilot study.

Objectives: To assess the ability of sedentary, frail subjects aged 80 and older to train in a community-based exercise program and to evaluate clinical factors that predict improvements in peak oxygen consumption (VO2peak).

Design: Pretest, posttest.

Setting: Charlestown Retirement Community, Catonsville, Maryland

Participants: Twenty-two (11 male, 11 female; mean age +/- standard deviation = 84 +/- 4.
