A bloodstream infection in a patient with a central line does not answer where the organism came from. The investigation should begin with the reason for the line and follow its entire life, from insertion through each access, dressing change, culture, and removal. Other possible infection sources must be evaluated on the same timeline.
Identify the catheter and why it was needed
Record the catheter type, manufacturer, lot, insertion site, number of lumens, insertion date, and operator. The order and treatment plan should explain why central access was selected and whether the need continued each day. A peripherally inserted central catheter, temporary central venous catheter, implanted port, and dialysis catheter can present different clinical questions.
Preserve the insertion checklist, consent, ultrasound images, procedure note, and names of everyone present. The record should show hand hygiene, skin preparation, barrier precautions, equipment used, any break in technique, and any difficulty or repeat attempt.
Follow daily care and every access
Build a calendar of dressing and cap changes, line entries, infusions, blood draws, flushing, and site observations. Medication administration, pharmacy, nursing, and device records may reveal accesses that do not appear in a short line note. Identify redness, drainage, tenderness, a loose or wet dressing, or a damaged connector and what the staff did in response.
Staffing assignments, training records, supply substitutions, and infection-control audits may become relevant if the chart suggests a repeated practice rather than one isolated event. Evidence about general staffing should still be connected to the actual people and care at issue.
Reconstruct the infection timeline
Align temperatures, heart rate, blood pressure, laboratory results, symptoms, cultures, antibiotics, imaging, and transfer decisions. Keep the original microbiology reports, including collection site, time, organism, susceptibility, and time to positivity. Peripheral and line-drawn cultures can carry different meaning, and contamination must be considered.
If the line was removed, preserve the removal note, catheter-tip culture, condition of the site, and replacement-line records. A new line may create a second timeline that should not be merged with the first.
Distinguish surveillance from clinical causation
CDC’s current intravascular-catheter recommendations address personnel education, insertion, skin preparation, dressings, access, replacement, and removal. The guideline in effect and applicable to the catheter and setting should be used, not a generic checklist.
A CLABSI surveillance definition, a treating clinician’s diagnosis, and an expert causation opinion serve different purposes. A surveillance classification may help organize records, but it does not by itself establish the source of infection or civil liability.
Measure the consequences and test alternatives
Document sepsis, intensive care, organ injury, additional antibiotics, line removal or replacement, procedures, and added hospitalization. The analysis should compare other plausible sources, including urinary, pulmonary, wound, abdominal, or device-related infection, and explain why the central line is or is not the most likely source.
