Structured vs. Unstructured Data
Structured Data
Use controlled vocabs
Advantages
Create complete and accurate EHR for patient , max data completeness[comp] [bush]

Machine learning - easily edited and queried
Support reuse of clinical information [bush]
Clinical research analysis [bush]
Important for secondary use [bush]
Deceasing research costs [bush]
Increasing research speed [bush]
Increase patient-centered research [bush]
Support population health [kruse]
Big data [kong] - simple analysis
Disadvantages
Time-consuming [bush] [whydoctorshate]
Burden for the physicians [bush]
Negative impact on physicians, low acceptance of EHR [bush]
Less flexible [astera]
Limited save options [talend]
