How physicians can protect themselves from legal risk: document everything

When it comes to medical-legal risk, the danger rarely lies in missing a rare, hard-to-catch diagnosis. According to Dr. John Casey, director of medical education at OhioHealth Doctors Hospital, the bigger threat is failing to document your thought process — especially when a condition wasn't that uncommon to begin with. Speaking at OMED in Las Vegas, Casey emphasized that clear, thorough documentation of clinical reasoning (what you considered, what you ruled out, and why) is a physician's strongest shield against legal action.

Casey also flagged two areas that deserve more attention: AI in clinical settings and the concept of patient capacity. On AI, he noted that tools like AI scribes can actually reduce risk — as long as physicians maintain oversight. On capacity, he stressed that it's often misunderstood: it can fluctuate, vary by domain, and is not the same as legal competence.

Key Takeaways:

• Missing a rare diagnosis is rarely the legal problem — failing to document consideration of common ones is
• AI tools can enhance safety, but physician oversight remains essential
• Patient capacity is nuanced, fluctuating, and domain-specific — worth revisiting beyond medical school training

Why it matters: As AI reshapes clinical workflows and legal scrutiny of medical decisions intensifies, physicians who understand the evolving medical-legal landscape — and document accordingly — are far better positioned to protect both their patients and themselves.
