From the summary:
This report finds that state spending on prisoner health care increased from fiscal 2007 to 2011, but began trending downward from its peak in 2009. Nationwide, prison health care spending totaled $7.7 billion in fiscal 2011, down from a peak of $8.2 billion in fiscal 2009. In a majority of states, correctional health care spending and per-inmate health care spending peaked before fiscal 2011. But a steadily aging prison population is a primary challenge that threatens to drive costs back up. The share of older inmates rose in all but two of the 42 states that submitted prisoner age data. States where older inmates represented a relatively large share of the total prisoner population tended to incur higher per-inmate health care spending.
