Researchers and policy-makers have long compared health system performance. International comparisons raise awareness of health systems’ relative strengths and shortcomings, prompting policy debates and informing policy decisions. Yet determining how these international comparisons can be used to improve health system performance is challenging. Health systems can differ in many ways, including how they are governed, how they are funded, how they generate and deploy resources, and how they deliver services. While the international health community widely agrees that these functions influence health system performance, understanding of how much they matter, which ones matter most, and how they are affected by the context in which they operate remains limited. To gain relevant and meaningful insights from health systems comparisons that offer lessons for policy, we must agree on how to compare health systems. In this article, we argue that doing so requires collecting better, more granular data on a broad range of health system characteristics and using those data to choose the most appropriate health system comparators.

The choice of price index has major implications for comparative analysis. Despite their widespread use internationally, general price indices likely underestimate the contribution of price growth to overall health expenditure growth. We find that in addition to its reputation for having high health price levels compared to other high-income countries, the United States also faces health price growth for goods and services paid for by government and households in excess of general price growth. Furthermore, US households are exposed to greater health price growth than households in comparator countries.

Jonathan Cylus and colleagues argue that inflationary pressures mean the NHS may have reached the limit on its ability to contain costs for goods and staff without affecting care.
