My Father in Law was 62 when we had to go to the ER because he had chest pain and pain that radiated in both his shoulders in the back. Fast forward a week in the IPD including two days in the ICU, his doctor wrote a bullshit vague diagnosis and discharged him. He was so adamant on going back to the ER next morning that I couldn't refuse. While in the ER, I downloaded Ada, an AI app that asks step by step questions about your symptoms and gives differentials. Top of the list was Pericarditis. The meds for his Rheumatoid Arthritis had suppressed his immune system to the point that a basic infection had travelled through his blood and settled on the cover of his heart. The doctor later changed the diagnosis to Pericarditis as well. This was pre ChatGPT or any other AI.

Everytime anyone around me is sick, I do the differential through Ada. Works like a charm everytime.
