Objective: To assess the agreement between the functions of seven conf
igurations of Patient Data Management Systems (PDMS) and the Dutch spe
cifications prepared by the users prior to use. Design: An observation
al descriptive study with hospital visits of seven configurations of f
ive different PDMS systems including three commercial systems and two
locally developed systems, Setting: Seven Dutch level I intensive care
units in university and teaching hospitals. Measurements and results:
A substantial disagreement was found between the Dutch specifications
and the actual functions of the PDMS configurations tested. Between t
he PDMS configurations, major differences in key features, including '
'automated charting'', ''information and care planning'', and ''manage
ment information'', were observed. Automated charting is adequately su
pported by the three commercial systems. All configurations tested had
limited functions supporting care planning. In none of the configurat
ions tested was the required function present to support unit manageme
nt with reports on resource utilisation and outcome performance. The a
utomatic calculation of prognostic scores was either absent or incorre
ct. The implementation, the (continuous) configuration and the trainin
g required a substantial investment in costs and human resources. Conc
lusion: Today none of the PDMSs tested satisfy the Dutch specification
s, This can be explained by technical impossibilities of the systems a
nd shortcomings in the actual configuration or in the unit organisatio
n. The PDMS might beg:a come a valuable tool in improving the quality
of ICU practice, but full implementation of these systems according to
the specifications still has a long way to go.
