Infection Control at the Bedside: 2026 Best Practices for Nursing Teams
Hand hygiene compliance is necessary but not sufficient. Learn the layered infection-control practices that actually move CAUTI, CLABSI, and SSI rates.
The foundation: standard precautions
Standard precautions assume every patient could be infectious — because in practice, they could be. The non-negotiables:
- Hand hygiene before patient contact, before aseptic task, after body fluid exposure, after patient contact, after contact with patient surroundings
- PPE matched to the exposure risk, donned and doffed in the correct order
- Safe injection practices: one needle, one syringe, one patient, one time
- Respiratory hygiene at triage
Hand hygiene compliance averages around 40-60% in most facilities even after intervention. That is the single largest underperformed safety practice in healthcare.
Transmission-based precautions
Layered on top of standard precautions:
- Contact — gown and gloves; private room or cohort; dedicated equipment
- Droplet — surgical mask within 6 feet; private room preferred
- Airborne — N95 or higher; negative-pressure room; door closed
When in doubt, escalate. De-escalating later is cheaper than a unit-wide outbreak.
Bundle care for device-associated infections
Bundles are small, evidence-based sets of practices that move outcomes when applied consistently. The most important for nursing:
CAUTI bundle
- Insert only when clinically necessary
- Aseptic insertion and maintenance
- Keep drainage bag below bladder, never on the floor
- Daily review of necessity; remove as early as possible
CLABSI bundle
- Hand hygiene before line access
- Maximal barrier precautions on insertion
- Chlorhexidine skin antisepsis
- Optimal site selection
- Daily review of necessity
VAP bundle (where ventilators are nurse-managed)
- Head of bed 30-45°
- Daily sedation interruption and readiness-to-extubate assessment
- Oral care with chlorhexidine
- DVT and peptic ulcer prophylaxis
Audit, feedback, and culture
Bundles without measurement are aspirations. The pattern that works:
- Direct observation audits — not self-report
- Unit-level dashboards that update weekly
- Feedback that is timely and non-punitive
- Visible leadership: managers seen using PPE correctly, not just memos about it
Antimicrobial stewardship is a nursing role
Nurses see indications evolve in real time. Antimicrobial stewardship benefits from nursing input:
- Question broad-spectrum antibiotics after 48 hours without de-escalation
- Flag missing cultures before empiric coverage starts
- Advocate for IV-to-PO switch when the patient is tolerating oral
