Abstract
Since Medicare first implemented the home care Outcome and Assessment Information Set (OASIS) in 1999, we have learned a great deal about depression among the homebound elderly.

With depression rates at almost 15%, home care-along with nursing homes-has among the highest rates of any healthcare setting (Bruce et al., 2002; Parmelee et al., 1992; Jones et al., 2003).
