RESUMO

INTRODUCTION: The use of central catheters in intensive care is essential, but exposes the patient to the risk of a bloodstream infection. Although there is evidence to improve the care for these patients, there is a gap between knowledge and healthcare practices. This study was designed to describe the bundle implementation for central catheters in light of the knowledge translation (KT) conceptual framework in a neonatal unit and assess its impact on care practices with catheters. METHODOLOGY: A time-series quasi-experimental study design was conducted in a Brazilian neonatal unit, through 289 non-participant observations of professional practices before and after the implementation of the bundles. RESULTS: The deployment of two bundles was guided through the steps of a careful selection of adopting KT evidence and context-related and investment factors in the facilitation process. The implementation of the bundles was planned by a group manager, mediated by a facilitator, and guided by targets established by professionals. The biggest impact was on the maintenance of catheters; seven of eleven practices improved significantly (p < 0.01). The insertion of catheters showed lesser impact of change, with high adequacy ratios before implementation, but also presented satisfactory adherence to recommendations. CONCLUSIONS: This is the first Brazilian study using the KT conceptual framework to develop, implement, and evaluate the impact of central line bundles in a neonatal care environment, detailing the implementation process. It highlights the importance of accountability and staff involvement in all stages of the study.
