AcademyHealth CEO Aaron Carroll joined Roy Bejarano, Co‑Founder & CEO of SCALE Healthcare for an episode of Analyzing Healthcare for a discussion about the realities facing the U.S. health system today, including escalating costs, insurance design debates, and the trade-offs inherent in every policy choice.
As Bejarano outlined current pressures, such as rising premiums, shrinking coverage, and volatility across insurance markets, Carroll emphasized that these challenges cannot be traced to a single cause. He pointed back to themes he has explored in earlier writing, including a 2010 op‑ed, examining why U.S. health care costs are driven by everything, not one culprit. In that piece, he explains how each part of the system, from outpatient care to salaries, contributes to overall spending.
A key theme throughout the conversation was the need to look beyond insurance models. While public debate often centers on single payer versus free market approaches, Carroll stressed that the true cost drivers lie in how the United States delivers care. Most peer nations rely on publicly run or publicly supported systems for high‑cost specialty and hospital care, a stark contrast to the predominantly private, fragmented landscape in the U.S. Carroll described countries, like Switzerland and Singapore, who offer useful lessons on balancing regulated insurance markets with coordinated delivery systems, whether through Switzerland’s nonprofit insurance model and robust public hospitals or Singapore’s tiered approach to hospital care and patient choice.
Carroll also pointed to structural issues that rarely receive national attention, particularly the workforce and supply constraints that shape access and cost. Much of the physician pipeline, he noted, is dictated by long‑standing Medicare funding caps that limit the number of residency positions each year. Despite large academic health systems possessing significant resources and playing a central role in training clinicians, the number of federally supported residencies has remained largely unchanged. This issue affects the entire system, with only about 50,000 to 100,000 residency slots available annually. Regardless of population growth, hospital consolidation, or rising demand, the supply of new physicians remains constrained. As Carroll acknowledged, this benefits existing clinicians by maintaining higher salaries and job security, but it also drives higher prices, contributes to workforce shortages, and leaves rural and underserved areas with limited access to care.
Debates about insurance models often overshadow these deeper structural problems. Even as hospitals close or consolidate and the U.S. population grows, national discussions continue to focus on coverage rather than the underlying supply of providers needed to meet demand. Without addressing these constraints, Carroll argued, insurance reforms alone cannot resolve issues of affordability, access, or workforce distribution.
