22. Limitations Attributing people to practice sites is imperfect (consistent with plan payments) Results are sensitive to sample sizes Changes in rates are relatively small Slightly differential case-mix over time Secular trends affect the rates 22

23. Next Steps Adding Medicare and Medicaid FFS claims now Compare risk-adjusted (adjusted for age, gender, and health status) rates Program Evaluation Committee focusing on developing a more robust evaluation plan for CTC Comparison groups is slightly different Risk adjustment Meaningful subgroups Statistical tests Accounting for when practices joined CTC 23

24. Total Cost of Care Measures Measure is dollars per member per month ($PMPM) Raw expenditures based on allowed amounts Price-adjusted measures using HealthPartners Total Cost of Care Methodology (National Quality Forum certified) Risk-adjusted (similar to utilization rates) Currently benchmarking against known expenditures from plans as a validity check Using all costs instead of a subset (utilizations measures have exclusions) 24
