Contributors Ba’ Pham, PhDRobert Fowler, MD, MSc Peter Tanuseputro, MD, MScDouglas Manuel, MD, MSc Nancy Sikich, MScShamara Baidoobonso, PhD Petros Pechlivanoglou, PhDLes Levin, MD, MSc Murray Krahn, MD, MSc On behalf of the Health Quality Ontario Expert Panel on End-of-Life Care

End-of-Life Care EOL care consumes ~9% of the Ontario healthcare budget Recent policy review for quality improvement Evidence is needed for policy development Support patients according to their wishes and preferences

Objectives To evaluate the cost-effectiveness of in-home palliative team care for EOL patients and their family.

Palliative Team Care Timely identify palliative patients Need assessment Care coordination 24/7 access Symptom, social support interventions Psycho-spiritual care Bereavement care

Methods

Overview Model-based CEA Perspectives Healthcare payer’s (base case) Societal Time horizon: Last year of life Costs in 2014 Canadian dollar

Ontario Palliative Care Decision Model Markov microsimulation model Cycle from 1 to 365 days Cohort of decedents 76 years of age Simulate care transitions Project costs and health outcomes Percentage dying at home Days at home QALY

Model Structure Chronic conditions in LTC home Stable conditions at home Stable conditions at home with HOME CARE

Model Structure Acute illness required inpatient care Acute illness required ER care Chronic conditions in LTC home Stable conditions at home Stable conditions at home with HOME CARE

Model Structure Palliative prognosis required inpatient care Palliative prognosis required acute care in ER Acute illness required inpatient care Acute illness required ER care Chronic conditions in LTC home Palliative prognosis in LTC home Stable conditions at home Palliative prognosis at home with home care Stable conditions at home with HOME CARE

Model Structure Palliative prognosis required inpatient care Palliative prognosis in non-home hospice Palliative prognosis in palliative care ward or ALC Palliative prognosis in complex continuing care Palliative prognosis required acute care in ER Acute illness required inpatient care Acute illness required ER care Chronic conditions in LTC home Palliative prognosis in LTC home Stable conditions at home Palliative prognosis at home with home care Stable conditions at home with HOME CARE

Unpaid Care Cost Borne by Family

Quality of Life of Patients and Spillover Effect on Family

Conclusion In-Home Palliative Team Care is likely to be a dominant strategy The associated costs and consequences on the family is uncertain. Additional data are needed to reduce this uncertainty.

Limitations Impact on time to death was not considered QALY framework may not be appropriate for EOL care
