Payment incentives for community-based psychiatric care in Ontario, Canada

BACKGROUND: In September 2011, the government of Ontario implemented payment incentives to encourage the delivery of community-based psychiatric care to patients after discharge from a psychiatric hospital admission and to those with a recent suicide attempt. We evaluated whether these incentives affected supply of psychiatric services and access to care. METHODS: We used administrative data to capture monthly observations for all psychiatrists who practised in Ontario between September 2009 and August 2014. We conducted interrupted time-series analyses of psychiatrist-level and patient-level data to evaluate whether the incentives affected the quantity of eligible outpatient services delivered and the likelihood of receiving follow-up care. RESULTS: Among 1921 psychiatrists evaluated, implementation of the incentive payments was not associated with increased provision of follow-up visits after discharge from a psychiatric hospital admission (mean change in visits per month per psychiatrist 0.0099, 95% confidence interval [CI] −0.0989 to 0.1206; change in trend 0.0032, 95% CI −0.0035 to 0.0095) or after a suicide attempt (mean change −0.0910, 95% CI −0.1885 to 0.0026; change in trend 0.0102, 95% CI 0.0045 to 0.0159). There was also no change in the probability that patients received follow-up care after discharge (change in level −0.0079, 95% CI −0.0223 to 0.0061; change in trend 0.0007, 95% CI −0.0003 to 0.0016) or after a suicide attempt (change in level 0.0074, 95% CI −0.0094 to 0.0366; change in trend 0.0006, 95% CI −0.0007 to 0.0022). INTERPRETATION: Our results suggest that implementation of the incentives did not increase access to follow-up care for patients after discharge from a psychiatric hospital admission or after a suicide attempt, and the incentives had no effect on supply of psychiatric services. Further research to guide design and implementation of more effective incentives is warranted.
