Big problem here: You get more KPI, not better outcomes. Things like no doctor being willing to risk working a high risk patient.
We have already seen it with things like Medicare Advantage plans doing sign-up meetings on the second floor of buildings without elevators etc.
Medicare Advantage is a clusterfuck from start to finish (denying more claims than Medicare while also costing taxpayers more), precisely because it tries to micro-manage KPIs.
If you want to look at them done correctly, look at the FEP program. High-level KPIs that are difficult to game (without actually improving service & outcomes) tied to financial incentivizes.
