title: Long-term acute care: a review of the literature.
abstract: Long-term acute care (LTAC) represents a rapidly growing category of Medicare providers, but little is known about its quality, outcomes, and cost-effectiveness. Its defining characteristic, as set by Medicare, is an average length of stay of greater than 25 days. Modern LTAC emerged in the early 1980s as a setting for the weaning of ventilator-dependent patients. The industry has developed greatly in the last few years, with for-profit corporations dominating the field, and as Medicare expenditures have grown, new payment systems have emerged to limit spiraling costs. Although LTAC is mainly known for providing chronic ventilator weaning, the case mix is varied. The majority of outcome studies in this setting have been done on pulmonary patients, with fewer data available on nonventilator patients. This article analyzes studies of LTAC that are currently available, discusses some of the public policy issues surrounding this level of care, and suggests a research agenda, including a role for the field of geriatrics.
