Describe the key findings in the Total Risk Analysis research results.
The 5/50 principle - similar to the Pareto principle in that spend is concentrated in a relatively small percentage of the population. Several published studies have shown that for the overall population about 50% of U.S. health care spend can be attributed to roughly 5% of the population. This study shows that the 5/50 principle applies, but the concentration percentages vary by population. In 2017 the top 5% accounted for 63% of the spend for the Commercial population and 43% for the Medicare Advantage population
Consistency - The cost distributions, transition probabilities and source distributions for a specific population were consistent year over year during the study period. That said, the data may not be as consistent in the future because of changes in reimbursement methodologies, treatment patterns and the COVID-19 pandemic.
Coefficient of Variation - defined as the standard deviation divided by the mean, is relatively stable for both the commercial and Medicare populations. The coefficient of variation is a key element in determining the RV risk.
Leveraging - Health care costs increase every year, so the percentage of costs above or below a specified dollar amount changes every year. This concept is referred to as leveraging or the iceberg effect.
