1. What are the rates of readmission among the physicians in question from '94 - '98 and the readmission rate from '99 - '03? Show your work.

b) What is the marginal cost-effectiveness ratio (expressed in dollars) to determine the cost per health benefit associated with the additional charge of the placental cultures? In other words, if it can be determined that use of placental cultures reduces the number of re-admits, then what is that cost savings per avoided readmission? (Hint: Costs = readmission costs + placental culture costs. Determine net costs and net re-admit rates (per a) above] of the two (2) time periods. The ratio between the two can be expressed as a dollar figure.) Show your work.
