Clinical information technologies and inpatient outcomes: a multiple hospital study.
Approach to Improving Safety
Setting of Care
Implementation of clinical information technology remains slow in both ambulatory and hospital settings, due to cost issues and concern that IT may not lead to improvements in patient care. Prior studies in this area have found improvements in clinical outcomes associated with computerized provider order entry, but other high-profile failures 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 decision support—was associated with lower mortality rates in common inpatient conditions as well as lower rates of inpatient complications and costs. An accompanying editorial by David Bates discusses the policy implications of the study.
