managed care for the public

In class we often refer to Kaiser and their questionable service to the private sector, however it will be very interesting to see how managed care works for the "vulnerable" population since one can assume it will be even less desirable.  I would specifically like to know how they initially screen patients for outpatient appointments since Kaiser was recently under scrutiny for their system of screening over the phone using a script-like method to filter patients into the correct category.  If an HMO as large and well known as Kaiser has problems at this primary level then I'm sure a managed care facility treating the greater public is just as, if not more, overburdened in that department.  It would also be interesting to find out how they handle the medication side and how pharmacy coverage works.  Finally, I would ask if there were any statistical figures calculated to measure misdiagnosis, incorrect treatment, and such to account for accuracy.  Overall, I am looking forward to learning about their system which will hopefully eliminate any negative generalizations that I have about managed care.
