Stanford Tested AI for Discharge Summaries. The Biggest Benefit Wasn't Time.

Administrative work remains one of the largest sources of physician workload. Discharge summaries are a prime example, requiring clinicians to accurately document a hospital stay while ensuring continuity of care after discharge.
A team at Stanford Medicine evaluated whether an AI assistant could help.
AI drafts, physicians approve
Researchers developed MedAgentBrief, an AI agent that generated discharge summaries from the electronic health record. During a 10-week pilot in a 24-bed hospitalist unit, 11 physicians received AI-generated drafts each morning.
The summaries followed a standardized structure, including the reason for admission, hospital course, and diagnosis-specific updates. Physicians reviewed, edited, or discarded the drafts before finalizing them.
Adoption was high, with clinicians consistently choosing to work from the AI-generated summaries.
Safe enough, but not independent
The researchers reviewed 100 AI-generated summaries.
They found omissions in 25% of cases and inaccuracies in 20%. Hallucinations occurred in only 2%. Most issues were judged unlikely to cause patient harm, and no summary was associated with severe harm.
The findings reinforce the intended role of the technology: a drafting assistant rather than an autonomous documentation system.
Less cognitive work, not just less time
Physicians estimated the AI saved more than 10 minutes per discharge summary. Electronic health record data suggested the actual time savings were closer to three minutes.
Yet clinicians still reported lower burnout.
The study suggests that reviewing a draft requires less mental effort than writing a summary from scratch. For many physicians, reducing cognitive workload may be as valuable as reducing documentation time.
Why It Matters
The next generation of clinical AI may deliver its biggest impact by reducing administrative burden, allowing physicians to spend more attention on patient care rather than documentation.
