Hospital Compare sample rates were downloaded from the CMS web site:

Hospital population weights were computed based on estimates imputed from the denominators for Hospital Compare readmissions. Hospital referral region (HRR) rates were computed as the weighted average of the hospital sample rates within the HRR using the population weights.

State rates were computed as weighted averages of the hospital sample rates within the state.
