International Comparisons of High-Need, High-Cost Patients: New Directions in Research and Policy

Oct. 15th, 2021 — In partnership with ICCONIC, Health Services Research (HSR) is publishing an upcoming special issue, “International Comparisons of High-Need, High-Cost Patients: New Directions in Research and Policy.” The issue, to be released online November 4th, 2021 and in print November 12th, 2021, features six original research articles examining variation in healthcare utilization, spending, and outcomes among high-need, high-cost (HNHC) patients across eleven countries—Australia, Canada, England, France, Germany, the Netherlands, New Zealand, Spain, Sweden, Switzerland, and the United States.

Key Findings:
  1. Use of patient vignettes helps overcome some issues of data comparability across countries.
  2. Comparisons of care trajectories reveal important insights, including potential substitution effects across different care settings.
  3. There are relatively similar patterns of spending and utilization by age and sex across countries.
  4. HNHC patients incur more resource use than their healthier counterparts, but where this resource use occurs differs by health system.
  5. Drivers of high spending differ across countries, with the US having high prices per unit.
  6. These is substantial variation in health outcomes across countries, which does not appear to be correlated with health spending.
  7. Improvements in data access and data comparability are needed to carry out more robust health system comparisons in the future.
