Abstract:
An electronic health record (EHR) is a systematic collection of health information about an individual
patient. It includes a variety of types of observations entered over time by health care professionals,
recording observations and administrations of drugs and therapies, orders for the administration of drugs
and therapies, and test results. A well known problem is the consistency of EHR’s medication list: often
some of the prescribed drugs are missing, or some information is no more valid, e.g., some prescribed drugs
may be replaced by new drugs, or the dosage may be changed. In this paper we have focused on this
problem. We have restricted on EHRs and on prescriptions that are applications of the HL7 Reference
Information Model (RIM). Further, we have used the Refined Message Information Model (RMIM) to
specify the components that are extracted from prescriptions and transmitted into EHR. We have also
specified the criteria for medication list’s consistency, and the way it can be
maintained. In addition, we
have studied the ways the RIM can be used in linking patient’s prescriptions among themselves such that
the name of the link indicates its semantics. By viewing patient’s prescriptions as a linked data structure we
can improve the effectiveness of prescriptions’ retrieval as well as provide expressive queries on patient’s
health documentation.
