✅ Rule-based evaluator: Meets LCBI 1 for Escherichia coli — HO (HD 4).

Suspected event type LCBI
Date of Event (DoE) 2026-04-15
Hospital day at DoE 4
Onset HO

Repeat Infection Timeframe 2026-04-15 → 2026-04-28 (DoE + 13)
Meets LCBI 1 ✅ Yes
Meets LCBI 2 ❌ No
Meets CLABSI ❌ No
MBI organism present ✅ Yes (eligible for MBI-LCBI if host criteria met)
Why this verdict (6 steps)
  1. Date of Event = 2026-04-15 (from case row).
  2. Admitted 2026-04-12 (HD 1) → DoE on HD 4 → onset = HO.
  3. Infection Window Period = 2026-04-12 to 2026-04-18; RIT = 2026-04-15 to 2026-04-28.
  4. No central line documented — any LCBI here is NOT a CLABSI.
  5. Escherichia coli is a recognized Pathogen — a single positive blood culture is sufficient. **Meets LCBI 1.**
  6. Escherichia coli is an MBI-eligible organism. If host criteria (allogeneic HSCT + grade III/IV GVHD or ≥1L diarrhea/24h, OR neutropenia ANC <500 ×2 within 7d) are met, classify as MBI-LCBI rather than CLABSI.

The IWP (2026-04-12 to 2026-04-18) is anchored on the culture date per NHSN PSC Ch.2 — symptoms inside it count toward the surveillance criteria; symptoms outside don't. The Date of Event (DoE) is 2026-04-15 — the urine culture is the earliest criterion element (no qualifying symptom precedes it). The RIT (2026-04-15 to 2026-04-28) is the 14-day window during which no new event of the same type can be reported, anchored on DoE (DoE through DoE + 13).
