• Context of conventional health services delivery at each prison, in the predemonstration and demonstration periods.

• Inadequate or inefficient practices in the predemonstration period that werepotentially amenable to improvement via telemedicine.

• Barriers to effective use of the telemedicine network, as configured for this demonstration.

• Clinical feasibility for various specialties.

• Other constraints that affected the cost-effectiveness of the demonstration.
