The University of Pennsylvania School of Nursing has agreed to sell its operation serving low-income people 55 and older sick enough for a nursing home but want to keep living at home, to Trinity Health.

Terms of the deal, which was disclosed Tuesday, were not released. Penn said it plans to continue to use the program's West Philadelphia facility for training and research.

Trinity, which operates so-called Living Independence for the Elderly programs, or LIFE programs, through Mercy Health System of Southeastern Pennsylvania and other Philadelphia-area properties, is already the area's largest operator of the program that combines Medicare and Medicaid benefits.

In May, Trinity's local LIFE programs had 1,104 participants. Penn had 433. A third operator, NewCourtland LIFE, had 393.

Penn said it expected all 108 of the LIFE program's employees to be hired by Trinity, subject to standard hiring practices.

The deal came to light through a layoff notice filed last month with the Pennsylvania Department of Labor and Industry.

Trinity said the filing was standard practice during a change in ownership and that it did not expect any dramatic changes.
