*Care hours and costs provide interval data. 95% CIs were calculated with bootstrapping based on 1000 samples to allow for skewed data.
†Care hours per week and care costs per week are estimated using the computerised algorithm in the Northwick Park Care Needs assessment (NPCNA) which is built into the UKROC software.
‡The figures for Episode cost differ slightly from table 1 as this is the subsample of patients with paired NPCNA data.
