Information systems (IS) are increasingly important for measuring and impro
ving quality. In this paper, we describe our integrated delivery system's p
lan for and experiences with measuring and improving quality using IS. Our
belief is that for quality measurement to be practical, it must be integrat
ed with the routine provision of care and whenever possible should be done
using IS. Thus, at one hospital, we now perform almost all quality measurem
ent using IS. We are also building a clinical data warehouse, which will se
rve as a repository for quality information across the network. However, IS
are not only useful for measuring care; but also represent powerful tools
for improving care using decision support. Specific areas in which we have
already seen significant benefit include reducing the unnecessary use of la
boratory testing, reporting important abnormalities to key providers rapidl
y, prevention and detection of adverse drug events, initiatives to change p
rescribing patterns to reduce drug costs and making critical pathways avail
able to providers. Our next major effort will be introduce computerized gui
delines on a more widespread basis, which will be challenging. However, the
advent of managed care in the US has produced strong incentives to provide
high quality care at low cost and our perspective is that only with better
IS than exist today will this be possible without compromising quality. Su
ch systems make feasible implementation of quality measurement, care improv
ement and cost reduction initiatives on a scale which could not previously
be considered. (C) 1999 Elsevier Science Ireland Ltd. All rights reserved.
