7 SH Stroke Patients Outcome: Overall LOS  26

8 SH Stroke Patients Outcome: Overall Mortality

9 SH Stroke Patients Outcome: In-hospital Mortality at First Admission

10 SH Stroke Patients Outcome: Overall Readmissions

11 SH Stroke Patients Outcome: Readmissions within 7 days

12 Outline Strategies for Stroke Care and Prevention Targets to reduce the impact of Overall Mortality: Aged patients Subjects with Hemorragic diagnoses Assess presence of Carer at home Targets to reduce the impact of Mortality at First Admission: Aged patients Subjects with Hemorragic diagnoses Patients born in North-East Asia or North America Discharges from Medicine Clayton Targets to reduce the impact of Overall Readmissions: Aged patients Subjects with Hemorragic diagnoses Residents in Springvale, Bentleigh East, Oakleigh Targets to reduce the impact of Readmissions within 7 days after first discharge: Discharges from Emergency Clayton Residents in Dandenong Targets to reduce the impact of Long Stay: Patients Separated, divorced or widowed Aged patients Subjects with Hemorragic diagnoses Residents in Springvale
