^aThe number of patients included in the mSLICC is not given as some patients may be included in some months (when they have a regular GP) and not others; the mean of the percentage of all patients with appointments each month is given instead. The SLICC includes all appointments. ^bCompared with whole adult population. BB = Bice–Boxerman Continuity of Care Index. eFI = electronic Frailty Index. mSLICC = modified St Leonard’s Index of Continuity of Care. UPC = Usual Provider of Care Index.
