Why this verdict (8 steps)
  1. IWP = 2026-04-13 to 2026-04-19 (anchored on culture date 2026-04-16 ± 3 days per NHSN PSC Ch.2 UTI).
  2. Date of Event = 2026-04-16 (from case row).
  3. RIT = 2026-04-16 to 2026-04-29 (DoE + 13).
  4. Admitted 2026-04-12 (HD 1) → DoE on HD 5 → onset = HO.
  5. Indwelling urinary catheter (Foley) inserted 2026-04-13 → in place 4 calendar days on DoE → CAUTI attribution applies.
  6. Qualifying urine culture on 2026-04-16: Escherichia coli = 100,000 CFU/mL; Klebsiella pneumoniae = 50,000 CFU/mL — ≥10⁵ threshold met.
  7. Meets **SUTI 1a** — urinary device present + qualifying symptom (fever, suprapubic_tenderness) within IWP + culture criteria met.
  8. Plus the Foley meets the >2-day attribution threshold → **Meets CAUTI.**

The IWP (2026-04-13 to 2026-04-19) 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 2026-04-16 — the urine culture is the earliest criterion element (no qualifying symptom precedes it). The RIT (2026-04-16 to 2026-04-29) is the 14-day window during which no new event of the same type can be reported, anchored on DoE (DoE through DoE + 13).
