Why does the Lerxs white paper argue that digitized medical records may still be difficult for computers to use?

### Why this is right A computer needs consistent structure and meaning to compare records reliably. The white paper describes clinical notes with shorthand, diagnosis terms that vary between institutions, and laboratory results stored in inconsistent formats. Digitization alone does not resolve those differences. ### The concept **Interoperability** is the ability of separate systems to exchange and use information. **Semantic interoperability** adds the requirement that the receiving system understands what the exchanged information means. For example, two different written forms for the same diagnosis must be mapped to a shared meaning before software can safely compare them. ### The other options - **B. They are always stored only on paper.**: The paper says many records are digital, but their formats and meanings remain difficult for computers to interpret. - **C. They contain no clinical observations.**: Records contain observations; the problem is that those observations are not consistently represented. - **D. They cannot be connected to any patient identity.**: Identity is a separate platform layer, not the stated reason records are hard for computers to read. ### Terms - **Semantic interoperability**: The ability of systems to exchange information and interpret its meaning consistently. ### Remember Digitized data is not necessarily structured or meaningfully interoperable.
