Hospitalization and associated costs by caregiver identity. Estimates are taken from Model 2 with following variables in final model. Service utilization model. Acute inpatient service: patient age, gender, ethnicity, caregiver identity, comorbid status. Cost model. Acute inpatient cost: age, gender, ethnicity, caregiver identity, comorbid status, marital status, recurrent stroke. Reference group for caregiver identity variable is stroke patients with no caregiver. a Incidence risk ratio of hospitalization by caregiver identity (HOSPITALIZATION), b Multiplier of hospitalization associated costs by caregiver identity (COST). Abbreviation: IRR = incidence rate ratio. *: For hospitalization cost, the y-axis is the ratio of expected cost from Q2 to Q4 to the reference quarter (Q1) respectively
