# US healthcare ranks last among peer nations despite highest spending because access and equity failures override clinical quality

The Commonwealth Fund's 2024 Mirror Mirror report compared 10 high-income countries (Australia, Canada, France, Germany, Netherlands, New Zealand, Sweden, Switzerland, United Kingdom, United States) across 70 measures in five performance domains. The US ranked **last overall** while spending more than 16% of GDP on healthcare — far exceeding peer nations.

The core paradox: the US ranked **second in care process** (clinical quality when accessed) but **last in health outcomes** (life expectancy, avoidable deaths). This proves the problem is structural rather than clinical. The US delivers excellent care to those who access it, but access and equity failures are so severe that population outcomes are worst among peers.

## Domain Rankings

- **Access to Care:** US among worst — low-income Americans experience severe access barriers
- **Equity:** US second-worst (only New Zealand worse) — highest rates of discrimination and concerns dismissed due to race/ethnicity
- **Health Outcomes:** US last — shortest life expectancy, most avoidable deaths
- **Care Process:** US ranked second — high clinical quality when accessed
- **Efficiency:** US among worst — highest spending, lowest return

## The Spending Paradox

The top two overall performers (Australia, Netherlands) have the **lowest** healthcare spending as percentage of GDP. The US achieves near-best care process scores but worst outcomes and access, proving that clinical excellence alone does not produce population health.

## Evidence

- 70 unique measures across 5 performance domains
- Nearly 75% of measures from patient or physician reports
- Consistent US last-place ranking across multiple editions of Mirror Mirror
- US spending >16% of GDP (2022) vs. top performers with lowest spending ratios

## Significance

This is the definitive international benchmark showing that the US healthcare system's failure is **structural** (access, equity, system design), not clinical. The care process vs. outcomes paradox directly supports the claim that medical care explains only 10-20% of health outcomes — the US has world-class clinical quality but worst population health because the non-clinical determinants dominate.


### Additional Evidence (extend)

The NHS provides the inverse comparison: ranking 3rd overall in Commonwealth Fund Mirror Mirror 2024 despite having the worst specialty access and longest waiting times among peer nations. This reveals that the Commonwealth Fund methodology weights universal coverage, primary care access, and equity more heavily than specialty delivery outcomes. The US ranks last due to access/equity failures; the NHS ranks high despite specialty failures. Both demonstrate that no system optimizes all dimensions simultaneously—tradeoffs are structural.
