Stacey Richter interviews neurosurgeon Dr. Ahilan Sivaganesan (Dr. Siva) about replacing vague healthcare "value" claims with quantified outcomes and unit-level costs, introducing his Operative Value Index (OVI). They discuss how hospitals often lack true internal episode costs and how common quality metrics miss patient-reported outcomes and appropriateness across the full care journey.

Using time-driven activity-based costing (TDABC) and condition- or procedure-specific patient-reported outcomes, OVI creates a common mathematical language to compare surgeons, practices, or health systems, risk-adjust for confounders, and support steering/tiering and direct contracting for self-funded employers.

Siva describes transparency via bubble charts that spur clinician behavior change without new incentives and argues this infrastructure is essential as bundled payments and risk-based arrangements expand, framing a "Yahoo vs Google" shift from fee-for-service volume to measurable value.
