An accompanying perspective notes that providing enhanced primary care access was costly and produced a heavy workload. An average of 35 additional hours of appointments per week were made available per practice in the treatment group, resulting in ~33,000 additional primary care appointments booked at primary care practices and £3.6 million in costs. By contrast, about 11,000 emergency department visits were averted, which would have cost ~£827,000. Hence, expanding access to primary care did not result in a cost saving. It adds however, that the intervention may still be cost-effective, which requires longer-term data on health outcomes.
