F/U labs in transient population

Calling out to correctional nurses...

I need feedback in how your facility handles f/u labs within a transient population. Example H&H ordered X 3 months. First month OK but second month inmate is transfered to another facility. How do you track the labs to ensure contunity of care?

Thank you in advance for your replies.

We receive kite, inmate has appt with provider, labs ordered, inmate receives first lab (usually) then is transfered out. We have no way of knowing short of reviewing med rec or the inmate tells us. Need new system. Help!
