HAI 65.0% confidence 2026-01-18 11:10
Reasoning:

Case meets basic CLABSI eligibility criteria MBI-LCBI: Staphylococcus aureus is not an MBI-eligible organism No exclusion criteria met - classifying as CLABSI CLASSIFICATION: CLABSI - Central line in place 6 days at time of culture - Organism: Staphylococcus aureus - No alternate infection source identified - Meets NHSN CLABSI criteria Review flags: - Documentation quality is poor - limited clinical context

Confidence: 65% Model: llama3.1:70b Prompt: clabsi_extraction_v1
Pending Review 40.0% confidence 2026-01-17 22:31
Reasoning:

While the patient has a central line in place for over 2 days, the clinical notes mention recent abdominal surgery and possible intra-abdominal infection. This raises the possibility of an alternative source for the Staphylococcus aureus bacteremia. Further investigation is needed to determine if the central line is indeed the primary source or if the BSI is secondary to another infection.

Alternative Source: Possible intra-abdominal infection
Supporting Evidence:
Patient Information
Recent abdominal surgery with possible intra-abdominal source
Suggests a potential alternative source for the bloodstream infection.
Clinical Notes Context
Line site appears clean but cannot rule out catheter-related infection.
Indicates uncertainty regarding the central line as the primary source.
