Device-Associated Infections
Parent: MOC - Diseases by System · Workflow: MOC - Clinical Microbiology
Disease Notes
- CLABSI ✅
- VAP → Hospital-Acquired Pneumonia
- CAUTI / PJI / shunt (TBD)
Syndromes
| Syndrome | Disease note | First approach |
|---|---|---|
| CLABSI | CLABSI | Paired blood cultures; line removal rules |
| VAP | Hospital-Acquired Pneumonia | Lower resp culture; Respiratory Infections |
| CAUTI | TBD | Urine culture; avoid Rx asymptomatic bacteriuria |
| Prosthetic joint / graft / valve | TBD · Infective Endocarditis | OR cultures; Biofilm; ± explant |
| CSF shunt infection | TBD · CNS Infections | CSF culture/Gram Stain |
Pathogens (starter)
- Staphylococcus aureus · CoNS (TBD)
- Pseudomonas aeruginosa · Klebsiella pneumoniae · Escherichia coli
- Candida on lines (→ MOC - Mycology)
Key Concepts
- Biofilm → antibiotic tolerance ≠ AST resistance
- Source control (remove/replace device) often required for cure
