Which time horizon is associated with a Clinical Data Warehouse (CDW) analysis?
Answer
Long-term longitudinal patient history
One critical dimension separating the CDW from operational systems or general DWs is its focus on long-term perspective. While operational systems provide current status, the CDW is built to track patient journeys and treatment effectiveness across extended durations—months or years. This longitudinal view is crucial for public health studies, tracking long-term survival rates post-treatment, and understanding the cumulative impact of care decisions on patient outcomes over the patient's lifetime record.
