Cost per faller (in addition to usual care costs) and cost per fall estimates based on adjusted regression coefficients ((standard error), P value) regressing faller (dichotomous) or total number of falls (count) on the overall sum of acute care costs, rehabilitation costs and all costs directly related to falls by subgroup and across all groups

Coefficients adjusted for age, gender, admission diagnosis grouping, whether there was admission to a rehabilitation ward, admission health related quality of life (assessed by the EuroQol 5 Dimensions (EQ-5D) instrument), and history of falls in the 6 months prior to hospital admission.

OLS, ordinary least squares.
