PROFILE
Matthew Froggatt
Worked on the hartwigmedical/actin repository to enhance clinical data evaluation by refactoring the rule engine from complication-based to comorbidity-based logic. This involved replacing legacy rules with a new, comprehensive assessment that considers all comorbidities, streamlining risk evaluation and reducing maintenance complexity. Additionally, delivered an API improvement by exposing the text representation of the TrialPhase enum as a public field, simplifying external integration and client code. The work was implemented using Java and Kotlin, with a focus on code organization, enum manipulation, and refactoring. These changes improved decision-support accuracy and laid the foundation for scalable ICD-title coverage.

Aug 1, 2025In August 2025, delivered a comorbidity-based evaluation rule system for ACTIN, refactoring the evaluation logic to replace complication-based rules with a more comprehensive comorbidity-based approach. Deprecated older rules (HAS_ANY_COMPLICATION, HAS_COMPLICATION_WITH_ANY_ICD_TITLE_X) and introduced HAS_COMORBIDITY_WITH_ANY_ICD_TITLE_X to assess risk across all comorbidities. This work, tracked under ACTIN-2388, improves decision-support accuracy, reduces maintenance burden, and sets the groundwork for scalable ICD-title coverage.
