This paper presents the authors' experience with the development and use of
a document-centered electronic patient record (EPR) in a large teaching ho
spital. The development of the document-centered EPR began with the formula
tion of a set of critical hypotheses to facilitate both the continuation of
the best medical practice and the implementation and use of the EPR. An al
ternate and more conventional approach - the data-centered EPR - is compare
d with the document-centered EPR. Various benefits and pitfalls are discuss
ed. Finally, the choice was to offer both solutions in a tightly linked sys
tem. The need for an EPR which combines the document and data centered appr
oaches is a reflection of the more general discussion of what the medical r
ecord will be in the future. All too often, the need for structured data co
nflicts with the need for free texts and the power of expression. It is not
easy to evaluate the consequences of this initial decision. However, chang
ing the foundations of the EPR after its implementation is difficult and ex
pensive. Therefore, the selection of the correct orientation in a given hos
pital requires a broad-based discussion. (C) 2000 Elsevier Science Ireland
