Computer-based patient care information systems (PCIS) have emerged as an integral component of healthcare organisations.
Currently, 4 models of PCIS exist : the centralised model, the hub-and-spoke model, the network model, and the distributed model.
The centralised model has the advantage of a central patient database ; however, a major disadvantage of this model is the inability to easily interface with other software packages.
The hub-and-spoke model links satellite or feeder systems into a mainframe computer ; thus, each satellite has the ability to work independently.
This system is limited by the ability to interface satellite systems with the mainframe computer.
The network model works via a local area network (LAN) using client server technology which allows for high speed data access and transfer.
The network model does not provide an integrated view of patient information and can access only I host system at a time.
The distributed model is similar to the network model in design but provides for data and system integration via relational databases.
This allows for the creation of a central data repository and support for decision-support tools.
Computer-assisted decision-support has the potential to significantly improve clinical decision-making.
Six types of computer-assisted decision-support have been defined : alerting, interpreting, assisting, critiquing, diagnosing and managing. (...)
