Site-Tailored CDI Optimizer
The same lab values should not produce the same query at every hospital. This engine reads de-identified ICU data from an academic medical center and a community hospital network, finds conditions with clinical evidence but missing or vague documentation, and routes each one by that site's policy and its physicians' learned agreement patterns. A model trained on one site barely beats a coin flip at the other.

Pipeline
- Adapters map each site's raw tables (MIMIC-III and eICU have different schemas, units and code systems) to one shared encounter model.
- Condition rules flag clinical evidence for 10 CC/MCC conditions, such as Sepsis-3 or SIRS criteria, KDIGO creatinine rise, SpO2 with ventilatory support, BNP with IV diuretics, and hemoglobin drop with transfusion.
- Documentation check compares the evidence to what the site actually documented (billed codes at Site A, the clinician problem list at Site B) and labels it absent or nonspecific.
- Agreement model: a logistic model per site learns how often its physicians document the condition when evidence is present. Low-likelihood queries are held back, and conditions a site almost never documents go to education, not one-off queries.
- Ranking by impact (MCC over CC) × agreement likelihood, with a bump when an MCC would lift a low severity of illness, plus a DRG tier-shift estimate where grouper data exists.
Generative AI layer
An optional step drafts each query with Claude from the cited indicators only, following the ACDIS/AHIMA compliant-query practice: no leading, every reasonable option plus "Other" and "Unable to determine", and no mention of reimbursement. A grounding check blocks any draft that cites a number not present in the evidence, and note-review quotes must match the note verbatim. The queries on this page come from the rule-based template, so no API key is needed to view them.
Data and limits
- Site A: MIMIC-III Clinical Database Demo v1.4 (Beth Israel Deaconess Medical Center). Site B: eICU Collaborative Research Database Demo v2.0.1 (non-teaching Midwest hospitals). Both are open-access demo sets on PhysioNet under the Open Database License, accessed through the ricu demo packages.
- Demo sets are small (129 and 628 ICU stays), so the confidence intervals are wide. Billed codes and problem lists stand in for physician documentation, and DRG shifts are tier estimates rather than full regrouping.
- This is a portfolio demonstration and is not validated for clinical or billing use.
