*In the analysis, we use hospital admissions at 6 months as this measure includes subsequent hospital admissions at 1 and 6 months.
†Total unadjusted health and social care and societal costs were also significantly different using non-parametric testing such as the Wilcoxon (Mann–Whitney) test.
†The total intervention costs include 74 patients allocated to the hospital group that crossed over to CGAHAH and 29 patients allocated to CGAHAH crossed over to hospital, the cost incurred for initial hospital-at-home admission by the hospital arm is averaged over 274 patients, although the costs arise from the 74 patients who crossed over from the hospital group to CGAHAH. Similarly, the costs incurred for initial hospital admissions from the CGAHAH are averaged over 563 patients, although arise from the 29 patients who crossed over.
**Home care services are part of personal social services, data collected from the HRU questionnaire.
Total adjusted costs were adjusted for baseline gender known cognitive decline, baseline utilities and pre-randomisation costs and site as a random effect.
***Health care costs include primary care, outpatient attendance and hospital admissions.
