I believe Pharmavixen works in a setting like this, but in canada.
Cheers!
I work in a city jail, which is largely a "remand" centre, meaning the place where inmates reside after being arrested, before being sentenced (the "innocent until proven guilty" crowd). Because we get people right off the street, there's lots of drug and alcohol WD, and lots of untreated ailments; our doc diagnoses a couple of new type II diabetics every wk.
We also get people on track with their HIV meds, a service that wins us much praise from the HIV/AIDS treatment community, as all the meds are given DOT. We see CD4s increase, viral loads go down.
I don't do much dispensing; there's 600 of them and one of me, so the dispensing is delegated to the nurses, who pour most of the medication orders. I maintain the drug supply and prepare the methadone doses, and sometimes administer the methadone. The nurses will also hand me the charts of the more medically-complicated inmates to vet their medication orders. And I help them with the pharmacy software system.
I have spoken to American colleagues, and they do more dispensing, as Corrections is a much, much bigger industry in the US and their facilities have adequate pharmacy staffing. Per capita, the US has one of the highest incarceration rates in the world; there are over 2 million people in jail in your country. Most of these people are in state prisons, and there's about 160,000 or thereabouts in federal prisons. For more info, check out the
Federal Bureau of Prisons National Formulary, which talks about pharmacy practice in this setting.
Though if you go into Corrections, you may have to consider whether or not to be involved in preparing the solutions for lethal injection, if you have capital punishment in your state. Personally, I am opposed to capital punishment (not for religious reasons; I don't like the government having the power to execute its own citizens), and couldn't work in such a setting.
