LLM Classifications

HAI 90.0% confidence 2026-01-17 22:28
Reasoning:

The patient meets all criteria for a CLABSI. The central line was in place for more than 2 days at the time of culture, and the clinical notes state there is no clear alternative source for the Klebsiella pneumoniae bacteremia.

Supporting Evidence:
OTHER - 2026-01-16
Patient with Klebsiella pneumoniae bacteremia. Central line in place for 3 days. No clear alternative source identified.
Clinical note explicitly states no clear alternative source for the bacteremia and confirms central line presence for >2 days.
Confidence: 90% Model: gemma2:27b Prompt: clabsi_v1
HAI 80.0% confidence 2026-01-17 22:07
Reasoning:

Based on the clinical notes, the patient has a central line in place for 3 days and no clear alternative source is identified. This meets the NHSN CLABSI criteria, and therefore, I have classified this as a hai_confirmed with high confidence.

Supporting Evidence:
Assessment/Plan
Patient with Klebsiella pneumoniae bacteremia. Central line in place for 3 days.
Central line was in place for >2 calendar days, meeting NHSN CLABSI criterion
Assessment/Plan
No clear alternative source identified.
Lack of evidence for an alternative infection source supports CLABSI attribution
Confidence: 80% Model: llama3.1:70b Prompt: clabsi_v1
