Translating national childhood immunization guidelines to a computer-based reminder recall system within an immunization registry

To translate national childhood immunization guidelines to a computer-based reminder recall system- hierarchical system architecture design and combined approach of tabular and procedural knowledge representation are taken. Nested branches with hierarchical combinations of single antecedent variables are used to avoid logical incompleteness- redundancy and inconsistency. Mapping to the local electronic medical vocabulary is implemented to facilitate the integration with the local information system architecture. 26 second-level modules with 195 original branches and 121 final branches after pruning are encoded. 99.67% of the reminders are confirmed to be correct by SQL query.
