Notes: N=13,882. Jail is based on the date from booking into the facility while prison is time from release; dispensations refer to each unique patient interaction where medications were obtained; emergency medical events are based on the date of that encounter; DOC categorizes a release to parole as a release, so our data likely includes individuals under supervision though not specifically identified as such. Prevalence is calculated as the touchpoint N divided by the total number of overdose deaths (13,882). Rate is the touchpoint N for January 1, 2015, through December 31, 2021, divided by the total number of events from the respective administrative data set for that time frame and multiplied by 100,000.
