Databases for Outcomes Assessment

Graphic - Diagram showing how various types of data are rated in terms of data collection from automated to manual. The most automated are standard claims data. Those are followed by present on admission, numerical laboratory, vital signs, and, finally, other clinical data as the most manually collected. Standard claims data, present on admission, and numerical laboratory are labeled as clinically enhanced claims data.

Slide 3

Efficient Use of Clinical Data

Square Graphic. Reading from left to right. Analytic When Power is high, Cost to Collect is low and Cost to Collect is High for Glasgow Coma Score. When Analytic Power is low for Hemoglobin, Cost to Collect is also low. Cost to Collect is also high for FEV1.

Rules for Lab Data Transmission

• Cases for which data are required may be identified by
  • principal diagnosis
  • procedure
  • age group
• Each row will contain information about a single lab test on a single patient
• Data will be limited to
• specified time periods (e.g., from 30 days prior to admission until discharge)
• specified laboratory tests

Slide 11

Preparation for Submission of Lab Data

• Participating hospitals will
  • map their electronic data into the standardized flat file format using tools supplied by the project team
  • submit completed data maps for review by the project team
• Project team will
  • Supply standardized materials to support data mapping by participating hospitals
  • assist individual hospitals in preparing their data maps
  • review completed maps for completeness and accuracy
  • provide feedback and assistance as needed

Slide 12

Transmission & Analysis of Lab Data

• Hospitals will submit a test samples of lab data to the project team
• Project team will analyze test data and work with individual hospitals to ensure completeness and accuracy of data submission
• Hospitals will submit lab data periodically
• Project team will work with individual hospitals to ensure completeness and accuracy of data
• Project team will merge and analyze data
• Project team will report analytic findings to hospitals
