Primary Outcome Measures:
  • Adverse Drug Events [ Time Frame: 6 months ]
    Adverse drug events are measured through use of a computerized surveillance system augmented by focused structured human review

  • Medical Errors [ Time Frame: 6 months ]
    Medical Errors are identified through a computerized surveillance system with structured human review

Enrollment: 228
Study Start Date: August 2001
Study Completion Date: August 2007

Arms Assigned Interventions
Placebo Comparator: Routine Care
Usual care of patients in the ambulatory setting
Other: Routine Care
Routine Care
Experimental: Basic Clinical Decision Support
Providers use basic clinical decision support
Other: Basic Clinical Decision Support
The computerized physician order entry (CPOE) intervention provides physicians with a menu of medications from the formulary, default doses, and a range of potential doses for each medication. Physicians were required to enter dosage, route, and frequency for all orders. Also, CPOE ensured that all orders were legible and included the prescribing physician's signature. For a number of medications, the system displayed relevant laboratory results on the screen at the time of ordering. Other features included consequent orders, which are orders that should follow from other orders, and drug-allergy checking, drug-drug interaction checking, and drug-laboratory checking. This included checking for the most frequent drug allergies, about 80 carefully selected drug-drug interactions, and several drug-laboratory combinations
