So what is the most significant health care technology implemented in health care in the last thirty years? The DaVinci robotic surgery system? Proton Therapy perhaps? No, not those. We want diagnostic, not treatment, technologies.
The answer is advanced imaging. Thirty years ago, a patient presented with non-specific abdominal pain. How did we diagnose it? Palpate, lab tests, order an x-ray. No conclusive results? Send them off to surgery.
