Care Pathway Calculator

Healthcare pathways—from diagnosis to treatment—carry significant carbon footprints due to clinical visits, diagnostics, logistics, and energy use. CarePathwayCarbon.org aims to empower healthcare systems, policymakers, and clinicians to estimate and reduce the environmental impact of patient care journeys.

Project Overview

To build a robust, user‑friendly application that supports:

• Carbon footprint calculations aligned with recognised standards (e.g., GHG Protocol, ISO 14044)
• Interactive visualization of emissions by pathway components
• Easy-to-use interface for clinical personnel and sustainability professionals

Back‑end (.NET)

• Built the core calculation engine using .NET, translating carbon footprint methodologies into scalable server logic
• Modeled complex emission factors tied to clinical services, travel, diagnostics, and facility energy use
• Created RESTful endpoints to:
  • Accept pathway input parameters (e.g., number of visits, test types)
  • Deliver calculated total and per‑patient emissions
  • Ensured edge-case handling, input validation, and error resilience

Front‑end (React + TypeScript)

• Designed dynamic, responsive UI for input collection and result visualization
  • Sliders, dropdowns, and number fields for pathway variables
  • Charts and breakdowns showing carbon distribution across pathway elements
• Integrated with backend APIs using typed HTTP clients for predictable data flows
• Implemented user guidance and tooltips explaining emissions logic
• Ensured performance, accessibility, and responsive behavior

Conclusion

By combining .NET-powered calculation precision with a TypeScript-based React UI, we delivered a scalable, reliable, and engaging tool that empowers healthcare leaders to understand, compare, and reduce carbon footprints across clinical pathways. CarePathwayCarbon.org not only informs but enables sustainable decision-making in one of society’s most vital systems.
