Community-based specialist palliative care teams and health system costs at end of life: a retrospective matched cohort study.

backgroundAccess to community-based specialist palliative care teams has been shown to improve patients' quality of life; however, the impact on health system expenditures is unclear. This study aimed to determine whether exposure to these teams reduces health system costs compared with usual care.

methodsWe conducted a retrospective matched cohort study in Ontario, Canada, using linked administrative data. Decedents treated by 1 of 11 community-based specialist palliative care teams in 2009/10 and 2010/11 (the exposed group) were propensity score matched (comorbidity, extent of home care, etc.) 1 to 1 to similar decedents in usual care (the unexposed group). The teams are comprised of a core group of specialized physicians, nurses and other providers; their role is to manage symptoms around the clock, provide education and coordinate care. Our primary outcome was the overall difference in health system costs (among 5 health care sectors) between all matched pairs of exposed versus unexposed patients in the last 30 days of life.

resultsThe total cohort of decedents included 3109 matched pairs. Among matched pairs, the mean health system cost difference was $512 (95% confidence interval [CI] -$641 to -$383) lower in the last 30 days among exposed than among unexposed patients. In the last 30 days, the mean home care costs of the exposed group were $189 higher (95% CI -$151 to $227) than those of the unexposed group, but their mean hospital costs were $733 lower (95% CI -$950 to -$516).

interpretationOur study suggests that health system costs are lower for patients who have access to community-based specialist teams than for those who receive usual care alone, largely because of decreased hospital costs. Ensuring access to in-home palliative care support, as provided by these teams, is an efficacious strategy for reducing health care expenditures at the end of life.
