Slide 2

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

Analytic Power   Cost to Collect
Low High
High POA Codes, Albumin Glasgow Coma Score
Low Hemoglobin FEV1

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.
