Notes: Intervention group denotes care in a CGA unit; control group denotes conventional care. For each HUI-3 dimension, the average self-rated single-attribute utility scores at index and 3-month follow-up are reported. Similarly, the average self-rated EQ-VAS scores at index and follow-up are reported. At follow-up, the total mortality, number of hospital days and in-hospital care costs are reported. The analyses excluded missing observations for the hearing dimension. P-values were calculated from means by Student’s t-test, except for mortality and rehospitalizations, for which χ²-test was used. For rehospitalizations, percentages were calculated by the use of 198 (intervention group) and 192 (control group) as denominators.
