The staggering cost of cancer treatment has led to widespread calls for changes in care delivery. 1 After nearly 50 years, the war on cancer has resulted in breakthrough treatments and survival improvements for multiple cancers. 1 Corresponding advances in care delivery, however, lag far behind.As we near the 50th anniversary of the National Cancer Act of 1971, care delivery is ripe for change. The current adult cancer care model-in which highly trained physicians craft discrete solutions for each patientwill be challenged in the face of increasing treatment complexity, increasing cancer prevalence, looming physician shortages, and rapidly shifting payment models that require health systems to bear financial consequences of unwarranted clinical variation. 1,2 We have an opportunity now to articulate a new model for care delivery. The model, rooted in humanmachine collaboration, could be implemented immediately in cancer care. Furthermore, it could lay a blueprint that may have broad applicability across other clinical domains.

Following the reauthorization of the Children's Health Insurance Program (CHIP) in 2009, fifteen states raised their CHIP income eligibility thresholds to further reduce uninsurance among children. We examined the impact of these expansions on uninsurance, public insurance, and private insurance among children who became newly eligible for CHIP after the expansions. Using a difference-in-differences approach, we estimated that the expansions reduced uninsurance by 1.1 percentage points among the newly eligible, cutting their uninsurance rate by nearly 15 percent. Public coverage increased by 2.9 percentage points, with variations in take-up among the states. A better understanding of these state-level differences in take-up could inform efforts to enroll children who remain uninsured but are eligible for CHIP. CHIP is up for reauthorization in 2015, and further funding will be needed to maintain the program, which provides insurance to children who might not have access to affordable private coverage.
