California Department of Corrections and Rehabilitation (CDCR) houses over 170,000 inmates in 33 adult prisons so it can be challenging to provide timely access to healthcare services while ensuring the safety of staff and inmates. Using ExtendSim, a prison medical program was modeled addressing the full continuum of healthcare services. After running over 350 different scenarios, five specific recommendations were made that improved the percent of inmates completing medical processing within six hours from 36% to 91% achieving the goals of the CDCR.
