Agentic Patient 7: How to Use AI as a Caregiver — Without Letting It Diagnose | Pratik Desai

AI couldn't cure his mother's stage 4 cancer. It caught three near-fatal errors, found a same-day appointment, and helped her leave on her own terms.

When Pratik Desai's mother was diagnosed with stage four duodenal adenocarcinoma — a rare cancer with roughly 3,000 US cases a year — she was nearly discharged without an oncology appointment. Over the next 76 days, Desai used AI at her bedside, from 5am to 10pm, to understand each report, prepare for every appointment, and push a stretched health system to move at the pace her diagnosis demanded. This is a frank account of where AI helped, where it didn't, and the line he refuses to cross.

This is a 1:1 interview in The Agentic Patient — a Faces of Digital Health series on how patients and caregivers actually use AI: which tools, which prompts, and which guardrails.

GUEST

Pratik Desai — New Jersey-based AI practitioner; caregiver and builder of a free, local AI tool for patients

WHAT THE CONVERSATION COVERS

- Using AI to interpret a biopsy report and push for a same-day "stat" CT scan

- Why AI and the doctors agreed on the care — and clashed on the speed

- Finding a same-day oncology appointment through an AI-assisted network search

- An error-riddled CT report the AI refused to read — and what it did to trust

- Running three Claude "personas" as built-in second and third opinions

- A local, open-source AI tool that keeps medical data off the cloud

- How to prompt as a patient or caregiver: awareness, knowledge, advocacy — not diagnosis

- Where AI failed him: prognosis, and the rule he broke under pressure

- Defining quality of life when the outcome is already known
