How to use
Before you start
Have the patient's current EVD data at hand: pathology, drain status, output, ICP, exam, vitals, labs.
Minimum to run: primary pathology and drain status. Everything else is optional.
Blank ≠ normal. Unentered fields are treated as "not assessed," not as reassuring.
De-identified or simulated inputs only. Nothing is stored or transmitted. Educational prototype, not a medical device, does not replace clinical judgment or escalation.
-
Entering the patient
Work top to bottom through the numbered sections. Conditional fields open as needed: aSAH reveals Hunt-Hess and modified Fisher; postoperative reveals procedure and post-op day.
Use the sliders for ICP, drain height, and output; abnormal values flag automatically.
Enter what you have. The assessment sharpens with more detail.
-
Generating the assessment
Run once pathology and drain status are in.
Missing the minimum → the tool states exactly what it needs, no guess.
Unreliable exam (sedated, unassessable) → a caveat prints and the output will not read as reassuring.
-
Reading the output, top to bottom
Banner: highest level of concern (escalate / intervene / routine).
Assessment: one-line clinical summary.
Impression: prioritized differential.
Recommended next steps: action list across all active concerns.
Evidence-to-action: problem list, per-problem management, and supporting guideline sources.
Diagnostic synthesis: each finding traced to its inference.
-
Use case-fit
Adult patients; management of an indwelling drain, not insertion.
Bedside recognition, escalation triage, rounding, and handoff documentation.
Thresholds tagged as institutional convention require local calibration before real use.
