Case study 03
The 112,000-character summary
A case study from the 433-record AI indexing review
The setup
One record in the 433-record dataset had a human Medical Summary of 112,000 characters, roughly 56 pages of single-spaced text. By any measure, this was an exhaustive document. The human reviewer clearly invested significant time and attention. The intuitive assumption is that this level of effort would close the gap between human and AI indexing.
It didn’t.
What the AI found that the human missed (9 clinician-documented items)
| Finding | Why it matters |
|---|---|
| Diabetes mellitus type 2 | A major metabolic comorbidity affecting wound healing, surgical risk, medication choices, and recovery timelines. Missing it means downstream clinicians don’t know this patient is diabetic. |
| Acute right hemiparesis status post t-PA | The patient had a stroke severe enough to receive t-PA (a clot-busting drug administered only in acute stroke). A life-threatening event that changes the entire clinical picture, anticoagulation, neurological monitoring, rehabilitation planning. |
| Symptomatic cholelithiasis | Gallstones causing symptoms, relevant to surgical planning and abdominal symptom evaluation. |
| Revision to laparoscopic sleeve gastrectomy | The patient had prior bariatric surgery. This affects nutritional status, GI anatomy, and is critical context for any future abdominal procedure. |
| H. pylori gastritis | An active gastric infection requiring treatment, relevant to the patient’s GI history and medication interactions. |
| Plantar fasciitis | A musculoskeletal condition affecting mobility and rehabilitation planning. |
| 3 additional clinician-documented findings | The study identified 9 total; the 6 above are the most clinically significant. |

“When even a 112,000-character summary leaves out a stroke and a prior bariatric surgery, the bottleneck isn’t human effort, it’s human bandwidth. A person reading hundreds of pages cannot hold every detail, and the details that slip through are unpredictable.”
Supporting data point
Across all 433 records, 18 summaries were described by the reviewer as “thorough” or “exhaustive.” Every single one still had identified gaps.
