Project Overview

PGxBridge is a healthcare systems strategy project designed to accelerate pharmacogenomic adoption in Australian clinical practice. The project responds to a structural gap in precision medicine: pharmacogenomic science is clinically useful, but it remains disconnected from the real prescribing workflow. Instead of framing the solution as a standalone app, PGxBridge proposes a national precision prescribing infrastructure layer that embeds genomic intelligence directly into electronic medication ordering. The proposed model integrates four components: smart prescription triggers, rapid PGx testing pathways, clinician-facing decision support, and a reimbursement strategy through pilot subsidies, insurer co-funding, and eventual MBS integration.

Strategic Framing

Problem

Pharmacogenomics remains outside routine prescribing workflows, creating clinical, operational, and reimbursement friction.

Insight

The adoption gap is not caused by weak science, but by poor system integration at the moment prescriptions are written.

Solution

Embed PGx intelligence into EHR prescribing through trigger-based testing, rapid workflows, and actionable clinical decision support.

What I Did

  • Framed the problem as a healthcare system adoption challenge rather than a pure technology or awareness problem.
  • Designed a four-layer precision prescribing infrastructure: smart trigger, rapid PGx pipeline, clinical decision support, and reimbursement engine.
  • Built the health economics logic around medication-related admissions, avoided readmissions, testing cost, and pilot-scale cost-offset assumptions.
  • Mapped the stakeholder incentives across clinicians, hospitals, patients, pathology labs, insurers, and government health authorities.
  • Developed the implementation roadmap from a cardiology-focused clopidogrel pilot to multi-drug expansion and national infrastructure adoption.
  • Created a clinical decision support demo showing how PGxBridge would surface CYP2C19 risk and recommend safer prescribing alternatives inside an EHR-style workflow.
  • Positioned the project as a healthcare transformation proposal rather than a consumer health product.

System Design

Four-Layer Infrastructure

  • 1. Smart prescription trigger inside EHR workflow
  • 2. Rapid saliva-based PGx testing pathway
  • 3. Traffic-light clinical decision support interface
  • 4. Reimbursement pathway through subsidy, insurer, and MBS

Pilot Strategy

  • Start with post-PCI clopidogrel prescribing
  • Target high-risk, high-cost, evidence-backed use case
  • Measure alert acceptance, turnaround time, switch rate, and avoided readmission
  • Scale into SSRIs, warfarin, tamoxifen, and national PGx infrastructure

Reflection

This project helped me understand that healthcare innovation is rarely won by technology alone. The hardest part is not proving that pharmacogenomics works scientifically, but designing a system where clinicians can actually use it at the point of care. The strongest learning was the importance of workflow-native design. A recommendation is only valuable if it appears at the exact moment a clinical decision is being made, in a form that reduces cognitive load rather than adding another task. This shaped the entire PGxBridge logic: clinicians should not need to interpret raw alleles; the system should translate genomic evidence into prescribing decisions. Another key reflection was the role of business strategy in healthcare systems. Reimbursement, stakeholder incentives, implementation sequencing, and operational feasibility are not secondary details — they determine whether a clinical innovation scales. The project pushed me to think like a healthcare strategy consultant: define the adoption bottleneck, identify the highest-ROI starting point, build a credible pilot, and connect the solution to system-level economics. Overall, PGxBridge became less of a product mockup and more of a strategic infrastructure proposal for precision medicine adoption.
