Hardest Part

Preventing hallucinations in medication reconciliations and follow-up care instructions while synthesizing unstructured clinical notes from a multi-day hospital stay.

Min Viable Scope

Generate text drafts strictly for straightforward single-condition inpatient discharges. Deliberately exclude complex ICU transfers, multi-specialty chronic patients, and direct medical billing code generation.

Cold Start Problem

Training a reliable extraction model requires access to real multi-day patient EHR histories locked behind HIPAA compliance. Break this by securing a single community hospital as a design partner, deploying securely to process their data locally in exchange for physician validation feedback.

Time To First Value

1 to 2 weeks of onboarding to map local hospital templates and secure read-only EHR integration

Technical Difficulty

High

Wedge

Target independent regional hospitalist management groups to bypass the multi-year procurement cycles of massive enterprise health systems. Focus exclusively on patients with complex, multi-day stays where the manual synthesis pain is highest, delivering via a SMART on FHIR integration. Expand by moving upstream into daily progress notes and ultimately the admission history and physical (H&P).

Timing

Large language models now possess context windows capable of ingesting the entire longitudinal electronic health record of a multi-day hospital stay simultaneously. This eliminates the chunking and hallucination issues that previously prevented AI from accurately summarizing complex, extended patient encounters.

Why This ICP

Hospitalist groups bear the brunt of inpatient documentation and face direct pressure from hospital administration to improve bed turnover metrics. They feel the acute pain of discharge delays and have the concentrated buying power to adopt specialized tooling faster than broad enterprise hospital IT.

Size Of Prize

~50,000 US hospitalists × $5,000 annual per-seat software spend equates to a ~$250M addressable market for inpatient discharge drafting.

Gap Narrative

Hospital discharge summaries require physicians to manually synthesize days or weeks of clinical notes, labs, and consults, taking 20 to 40 minutes per patient and delaying bed turnover. Current dictation tools only transcribe what the physician dictates, forcing the clinician to still perform the mental synthesis of the entire hospital stay.

Defensibility

Defensibility stems from deep electronic health record (EHR) workflow lock-in and localized style alignment. The core summarization capability is increasingly a commodity provided by foundational models, meaning long-term moats rely entirely on complex, custom integrations into Epic or Cerner that become too operationally disruptive for a hospital to rip out.

Why This Thesis

A Copilot Software approach fits the clinical liability model perfectly because physicians must retain ultimate sign-off on the medical record. Drafting the document in the background and presenting it for review turns a 30-minute blank-page synthesis into a 3-minute editing task without altering the chain of medical accountability.

Kill Thresholds

• Pilot-to-paid conversion rate < 50% after 90 days
• Manual edit ratio > 25% of total generated text
• Physician D30 active usage < 40%
• IT security and EHR integration review > 60 days

Leading Metrics

• Median physician time spent per discharge summary
• Manual edit character ratio per AI-generated document
• Weekly active usage rate per boarded hospitalist
• HL7/FHIR integration deployment time in days

What Proves Right

Hospitalists generate at least 80% of their discharge summaries using the tool within the first 30 days of deployment. Health systems convert 90-day pilots into annual enterprise contracts at a $150k minimum base tier due to measured reductions in bed turnover times. The median time a physician spends drafting a discharge summary drops from 15 minutes to under 4 minutes with minimal manual edits.

What Proves Wrong

Physicians abandon the tool because the AI misses critical post-acute care instructions or medication reconciliations, requiring heavy manual rewriting. Hospital IT departments block pilot deployments due to integration friction with Epic or Cerner workflows. The time spent correcting AI output exceeds the time it previously took to dictate the summary via incumbent tools.
