Abstract
To evaluate the cost effectiveness of a short-term home health care program for older people, Home Hospitalization (HH), compared with the alternative of regular ambulatory care with general or geriatric hospitalization as necessary. Our HH was initiated in November 1991 to serve Jerusalem residents. Program staff included physicians, nurses, and paramedical professionals. Other medical/hospital services were provided nonselectively by the general medical personnel of the various hospitals in Jerusalem. Patients over the age of 65 were either referred to the HH program (study group, n = 36,500) or to routine medical care (control group; n = 9000) depending on their Sick Fund assignment. Hospital utilization rates per enrollee were studied prospectively and compared both between the two groups and with hospitalization rates in the year before the initiation of the program. During the first 26 months of operations, the HH program cared for 741 older persons for a total of 37,290 days' care at an average daily costs of $30.06 (1992) and $23.64 (1993). Annual general hospitalization rates per person declined in the study group from 2.80 days in the 1991 baseline period to 2.65 days in 1992 and to 2.54 days in 1993. Hospitalization rates in the control group increased from 2.62 in 1991 to 2.70 days/member and 2.71 days/member in 1992 and 1993, respectively. Annual geriatric hospitalization rates declined considerably in the study group from the 1991 baseline of 1.49 to 1.34 (1992) to 1.33 (1993). The control group experienced a small decrease from 1.64 (1991) to 1.58 (1992) and then a rise to 1.68 days per member in 1993. For the 26-month duration of the program, estimated savings of 20,773 general hospital days ($5.54 million) and 8486 geriatric hospital days ($0.98 million) exceeded its costs ($0.97 million), providing a cost/benefit ratio of 5.7/1. In addition, patient satisfaction was high. The HH program provided a cost effective substitute for care in a geriatric or general hospital for Jerusalem's elderly.
