title: Two methods for developing and maintaining a database of clinical information on outpatient encounters: a comparison of process, costs, and benefits.
abstract: We describe and compare two relational databases that capture and store clinical information about ambulatory patients. One system is based on an encounter form; the other is a "parasite" that passively collects data from other hospital computers. We compare the system development processes, costs, and benefits of these two computerization strategies.
