On March 11th, 2026, I did something most patients never think to do. I wrote a detailed clinical letter to my pulmonologist before my scheduled coronary angiogram.

I listed every medication I was on. I referenced findings from my January review. I flagged my persistent airway sensitivity, post-nasal drip, and exertional breathlessness. I asked a specific, considered question: was there anything from the respiratory side I should be mindful of before a cardiac procedure?

I am a dentist with 25 years of clinical experience. I know how to communicate with specialists. I know what information matters. I sent that letter 16 days before my angiogram.

I got no reply.

By Chance

The angiogram went ahead on March 27th. By chance, my pulmonologist happened to be at the hospital that afternoon. He came to see me post-procedure. He examined me. He changed his hypothesis.

By chance.

That moment stayed with me. Not because the outcome was poor — it wasn't. But because I had done everything right as a patient. I had been proactive, clinically precise, and well-connected. I knew both my specialists personally. And I still fell through the gap.

What happens to patients who don't know the right questions to ask? Who can't write that letter? Who don't have a personal relationship with their specialist? Who are simply waiting — anxiously, quietly — for someone to join the dots?

The Midnight Question

At midnight, post-procedure, I found myself asking ChatGPT why I was tired. What my elevated IMR meant. Whether my medications were interacting with each other.

It answered clearly and calmly.

And that unsettled me more than anything else. Not because the AI was wrong. But because it shouldn't have been necessary. Two of Singapore's finest clinicians were managing my care. The gap wasn't clinical competence. It was communication infrastructure.

The Uncomfortable Truth

Here is something most clinicians won't say publicly.

Doctors are human. They see dozens of patients a day. They carry enormous cognitive load. They forget. And the healthcare system, as it is designed today, quietly passes the baton to the patient — expects them to follow up, connect the dots between specialists who have never spoken to each other, and hold the whole picture together themselves.
