The PREP system of nursing interventions, designed to increase preparedness (PR), enrichment (E), and predictability (P) in families providing care to older people, was pilot tested for acceptability and preliminary effectiveness. Eleven family units were assigned to the PREP group and 11 to a standard home health control group. The PREP group scored approximately one SD higher than the control group (p <.05) on the Care Effectiveness Scale, indicating greater preparedness, enrichment, and predictability. Further, on a rating of overall usefulness, the PREP group rated their assistance from PREP nurses (M = 9.75) as significantly higher (p <.01) than the control group rated assistance from the home health nurse or physical therapist (M = 6.57). Although not statistically significant, mean hospital costs for the PREP group ($2,775) were lower than for the control group ($6,929). Results provided support for a full intervention trial. ©1995 John Wiley & Sons, Inc.
