Roadmap

Three phases, in order of what's possible now.

Phase 2 and Phase 3 items are contingent on IRB approval, institutional partnership, and regulatory assessment — they are not commitments to a timeline.

Current sprint

Assembling open-data inputs (WorldPop, OpenStreetMap, GASTAT, MOH) for the first end-to-end Phase 1 pipeline run.

Phase 1 — Planning tier

In development

Open data only. Facility validation, both axes, quadrant classification, internal validation, manuscript.

Deliverables

  • Facility validation module (OSM vs. MOH)
  • Access engine (2SFCA, 30 and 60-minute catchments)
  • Vulnerability engine (socioeconomic, environmental, disease)
  • Quadrant classifier
  • Internal validation (sensitivity analysis, expert review)
  • Manuscript for peer review

Dependencies

  • IRB exemption for secondary analysis of public data

Phase 2 — Siting optimiser

Planned

Institutional data via KAIMRC IRB; location-allocation modelling; external clinical outcome validation.

Deliverables

  • Location-allocation siting optimiser
  • Integration of institutional data (MNGHA BESTCare records, Saudi Biobank)
  • External validation against clinical outcomes

Dependencies

  • KAIMRC IRB approval
  • Institutional data-sharing agreement

Phase 3 — Patient tier

Permission-dependent

National data linkage through institutional partnership; patient-facing emergency department routing, with fixed safety constraints.

Deliverables

  • Live ED occupancy feed integration
  • Triage questionnaire and estimated wait-time model
  • Single-cluster pilot deployment

Dependencies

  • National data linkage (NPHIES, Sehhaty, Weqaya)
  • SFDA regulatory clearance as clinical decision support
  • Emergency physician oversight
