Inside the Loop

We Built the Right Thing. They Said No for the Wrong Reason.

In 1998 iMetrikus connected home health devices to physician dashboards and offered it free to patients. The insurance industry passed. What they said in that meeting has haunted me ever since

San Diego. 1998. A conference room full of insurance executives. And a sentence I have never forgotten.


It started, as most things do, with a problem nobody wanted to admit existed.

The year was 1998. I had spent the previous decade inside operating rooms, building systems that captured data automatically from anesthesia monitors, ventilators, and IV pumps. ARKIVE had taught me one irreducible truth: the moment you stop asking humans to manually transcribe data and let the machines talk directly to each other, everything gets more accurate, more timely, and more useful.

The question I kept asking myself was simple. If we could do this in the OR, why couldn’t we do it at home?

Chronic disease patients (diabetics, cardiac patients, COPD sufferers) were generating diagnostic data every single day. Blood glucose readings. Blood pressure. Weight. Respiratory function. All of it measured, all of it clinically meaningful, almost none of it making it back to the physician between quarterly office visits. The patient drove to the clinic. The doctor reviewed three months of data in twelve minutes. Adjustments were made based on a snapshot, not a story.

We thought we could change that. So we built MetrikLink.


The concept was straightforward, which is not the same as saying it was simple.

MetrikLink was a home health connectivity hub, a small device that sat in the patient’s home and daisy-chained from the telephone line. No cell phones yet. This was 1998. You worked with what existed. We designed specialized adaptors for blood glucose monitors, blood pressure cuffs, thermometers, and scales. We added our own device: a spirometer called AirWatch that measured respiratory function for COPD and asthma patients.

I had spent enough time in China by then to know where to manufacture it affordably. We needed the

cost to be almost nothing because our model was radical for its time: free to the patient. Free to the physician’s office. No subscription. No hardware fee. No per-reading charge.

MetrikLink would upload the day’s diagnostic readings with a single button press. One button. An LED confirmed the transfer was complete. No screen. No menu. No instructions to follow. The whole transaction took seconds. That was intentional. We knew that complexity was the enemy of compliance, and compliance was everything in chronic disease management.

On the clinical side, we built a web portal called MediCompass. Physician offices and hospital clinics logged in and saw their patient population at a glance. Here is where we brought in a concept I had been thinking about since my aerospace days: the dark cockpit.

In aviation, a quiet cockpit is a safe cockpit. Pilots are not bombarded with constant status updates on systems that are performing normally. Instruments only demand attention when something is wrong. We applied the same logic to chronic disease management. MediCompass only surfaced a patient alert when a reading fell outside the bounds of their individual therapy plan. No alert meant the patient was on track. The clinic’s attention was reserved for the patients who actually needed it.

Patients had their own version of MediCompass, designed for home use rather than clinical workflow, where they could see their own trends and understand how their daily choices were affecting their numbers.

The technology worked. The clinical logic was sound. The business model was designed for scale.

All we needed was someone to pay for it.
