Aim:
To assess intensive care nurses' self-reported adherence to recommended microaspiration-prevention practices and explore potential implementation determinants.
Design:
Multicentre, cross-sectional.
Methods:
From December 2024 to February 2025, nurses in 31 intensive care units at 17 hospitals in Henan Province, China, completed a questionnaire on 22 preventive practices and 43 implementation-related items informed by the Theoretical Domains Framework. Bivariate analyses, a fully adjusted three-level mixed-effects model accounting for unit and hospital clustering, and generalised estimating equation sensitivity analyses examined associations.
Results:
Of 510 respondents, 476 were analysed. Mean adherence was 77.17/110 (70.15% of maximum), with basic care scoring highest (73.6%) and risk management lowest (67.2%). After adjustment, adherence was lower in units with 10-14, 15-19 and ≥ 20 beds than in those with < 5 beds; the 5-9-bed group did not differ. Both training exposures were associated with higher adherence in the primary analysis; only evidence-based practice training remained significant in the 14-item analysis. The lowest-scoring items concerned near-term implementation intention (3.10), competing priorities (3.21), and professional responsibility (3.29); the highest concerned time efficiency (4.19), workflow compatibility (4.15) and interest (3.94).
Conclusion:
Self-reported adherence varied across practices and domains. Intensive care unit bed capacity and training exposure were associated with adherence, and implementation-related findings identified potential areas for further investigation.
Implications For Nursing Practice:
Findings may guide intensive care unit nurses, nurse managers, and educators in strengthening targeted microaspiration-prevention training, clarifying responsibilities, integrating preventive practices into routine workflows, and reinforcing bedside supervision, particularly in units with 10-14, 15-19, or ≥ 20 beds.
Reporting Method:
The Strengthening the Reporting of Observational Studies in Epidemiology guidelines were followed. Patient or Public Contribution: None.

Sputum culture and sensitivity is a medical procedure used to diagnose bacterial infections in the respiratory tract and select the most appropriate antibiotics for treatment. This process involves analyzing sputum samples of thick and opaque secretions produced in the lungs and airways. These samples are collected from patients and then sent to the laboratory for analysis.
The test can identify various pathogens responsible for respiratory infections, including Streptococcus,...

Position the patient correctly to facilitate drainage of the affected lung segments. Manual or mechanical percussion and vibration can also be employed.
