Our Approach

We use national and regional patient-level datasets to explore variations in the utilization and costs of health services for four types of high-need individuals:

1) An elderly person with dementia

2) A frail elder with hip fracture and replacement

3) A patient with major complex conditions, including heart failure and diabetes

4) A young person with serious mental illness, including schizophrenia or bipolar disorder

Using available data, we aim to compare HN/HC personas across the entire care trajectory in 12 high-income countries: the United States, England, Canada, France, Norway, Sweden, Australia, New Zealand, the Netherlands, Germany, Switzerland and Spain.

Our study focuses on three main questions:

  1. What proportion of the four specific high-need patient types are identifiable in a large, sample of administrative claims data in each country?
  2. Are there meaningful differences in patterns of spending and utilization associated with these four high-need personas across countries?
  3. How do patient outcomes for these high-need personas, including readmissions and mortality, vary by country?
