This systematic review evaluated quality improvement (QI) interventions to prevent healthcare-associated infections among neurosurgical and neurological ICU patients. Seventeen primary studies from 14 countries were included in a narrative synthesis; the evidence was predominantly non-randomized. Across studies, structured interventions were associated with lower device-related infection rates. The largest reported change was in EVD-related infections, which fell from 14.35 to 3.21 per 1,000 catheter-days after implementation of care bundles. The review also found reductions in ventilator-associated pneumonia and catheter-associated urinary tract infection rates following structured prevention strategies.
Key findings
- After EVD care-bundle implementation, EVD-related infection rates decreased from 14.35 to 3.21 per 1,000 catheter-days.
- Following structured educational interventions, VAP rates decreased from 68.2 to 47.4 per 1,000 ventilator-days.
- Following structured educational interventions, CAUTI rates decreased from 24.9 to 13.4 per 1,000 catheter-days.
- One study reported 20 consecutive infection-free months after adoption of an interprofessional EVD bundle.
Why it matters
Neurosurgical ICU patients often require invasive devices and may have prolonged stays, creating substantial opportunities for device-associated infection. The review suggests that structured bundles, staff education, and compliance monitoring can reduce infection rates across different neurocritical care settings. These findings highlight infection prevention as a potentially important component of care, while the largely non-randomized evidence warrants measured interpretation.
What to keep in mind
The evidence base was predominantly non-randomized, and the review used a narrative synthesis; the abstract does not report a pooled effect estimate.
