Not HAI 80.0% confidence 2026-01-18 13:03
Reasoning:

Case meets basic CLABSI eligibility criteria MBI-LCBI: Escherichia coli IS an MBI-eligible organism MBI-LCBI: Patient meets population criteria - Neutropenia documented in notes (ANC value not extracted) MBI-LCBI: Mucosal barrier injury documented - mucositis (grade 3) CLASSIFICATION: MBI-LCBI - Organism (Escherichia coli) is intestinal/oral flora - Patient meets population criteria (Neutropenia documented in notes (ANC value not extracted)) - Mucosal barrier injury documented (mucositis (grade 3)) Per NHSN, this is MBI-LCBI, not CLABSI Review flags: - Verify ANC value for MBI-LCBI neutropenia criterion - MBI-LCBI classification requires IP verification

Alternative Source: MBI-LCBI (mucosal barrier injury)
Supporting Evidence:
Progress Note: 2026-01-18
Mucositis documented (Grade 3)
MBI-LCBI: Mucosal barrier injury factor
Progress Note: 2026-01-18
Neutropenia documented
MBI-LCBI: Immunocompromised status
Progress Note: 2026-01-18
Stem cell transplant (allogeneic)
MBI-LCBI: Transplant status
Contradicting Evidence:
Progress Note: 2026-01-18
Gut organism (Escherichia coli) in neutropenic BMT patient with severe mucositis
Possible alternate source: gastrointestinal
Confidence: 80% Model: llama3.1:70b Prompt: clabsi_extraction_v1
