This study examines the impact of preventive activities on costs of primary and secondary care in English primary care practices, focusing on people with serious mental illness. The findings suggest that these activities are associated with cost reductions in both primary and secondary care, with the cost savings in secondary care being significantly larger. The financial incentives for primary care physicians to participate in these activities were smaller than the total cost savings produced, indicating the potential for further increasing welfare through changes in incentive design.
A largely unexplored part of the financial incentive for physicians to participate in preventive care is the degree to which they are the residual claimant from any resulting cost savings. We examine the impact of two preventive activities for people with serious mental illness (care plans and annual reviews of physical health) by English primary care practices on costs in these practices and in secondary care. Using panel two-part models to analyze patient-level data linked across primary and secondary care, we find that these preventive activities in the previous year are associated with cost reductions in the current quarter both in primary and secondary care. We estimate that there are large beneficial externalities for which the primary care physician is not the residual claimant: the cost savings in secondary care are 4.7 times larger than the cost savings in primary care. These activities are incentivized in the English National Health Service but the total financial incentives for primary care physicians to participate were considerably smaller than the total cost savings produced. This suggests that changes to the design of incentives to increase the marginal reward for conducting these preventive activities among patients with serious mental illness could have further increased welfare.
