As discussed in Chapter 3, data were not available that allowed us to examine the alternatives with a national set of hospitals. Our exploratory analyses drew on two different sets of hospitals. The first set consists of the hospitals that are represented in the HCUP national sample. We were able to explore the sensitivity of DSH allocations to low-income patient definitions that rely on utilization or gross inpatient revenue data by payer class. The results of these simulations are discussed in Chapter 7.
By supplementing these analyses with detailed claim and financial information from California, New York and Wisconsin hospitals, we examined a broader set of potential DSH eligibility and allocation policies. We discuss these simulations in Chapter 8.
