Clinical information technologies and inpatient outcomes: a multiple hospital study.
Amarasingham R, Plantinga L, Diener-West M, Gaskin DJ, Powe NR. Arch Intern Med. 2009;169:108-114.
Implementation of clinical information technology remains slow in both
and hospital settings, due to cost issues and
that IT may not lead to improvements in patient care. Prior studies in this area have found
in clinical outcomes associated with
computerized provider order entry
, but other high-profile
have lessened enthusiasm for rapid IT implementation. This study, conducted at 41 Texas hospitals, provides support for IT's clinical benefits. Hospitals with electronic health records had lower overall mortality rates, and computerized order entry—particularly when combined with
—was associated with lower mortality rates in common inpatient conditions as well as lower rates of inpatient complications and costs. An accompanying editorial by
discusses the policy implications of the study.
