Application Effect Analysis of Bundle Nursing Intervention

Application Effect Analysis of Bundle Nursing Intervention Strategy Based on Targeted Surveillance in Reducing ICU Device-Associated Infections

This study aims to evaluate the impact of a multidisciplinary collaborative bundle nursing intervention based on targeted surveillance on the incidence of ICU device-associated infections (DAIs). The control group received routine nursing care, while the intervention group implemented a "targeted surveillance-multidisciplinary collaboration-bundle intervention" system. Infection rates, clinical outcomes, and intervention implementation were compared between the two groups.

Inclusion Criteria:

• Length of ICU stay ≥48 hours
• receipt of at least one invasive device operation (urinary catheter, ventilator, or central venous catheter [CVC])
• age ≥18 years
• signed informed consent by the patient or family member (authorized representative for patients with impaired consciousness)

Exclusion Criteria:

• Presence of DAI at admission;
• failure to complete at least one targeted surveillance indicator record during hospitalization
• voluntary discharge or loss to follow-up after transfer
• combination of severe immunodeficiency diseases (e.g., AIDS, long-term use of immunosuppressants after organ transplantation)
