Summary
A new education program significantly improved healthcare teams' knowledge of Bioelectrical Impedance Analysis (BIA) for fluid management in neonatal intensive care units (NICUs). This training is valuable for implementing BIA technology in clinical practice.
Area of Science:
- Neonatal intensive care
- Medical technology implementation
- Clinical research education
Background:
- Bioelectrical Impedance Analysis (BIA) offers a non-invasive method for assessing body composition.
- BIA may enhance fluid management strategies for critically ill and preterm infants.
- Implementing BIA in Neonatal Intensive Care Units (NICUs) requires specialized training.
Purpose of the Study:
- To develop and assess an educational package for multidisciplinary teams in the NICU.
- The package aims to facilitate the use of BIA in future research.
- Evaluate the effectiveness of the training program.
Main Methods:
- A mixed-methods approach was employed to evaluate the education package.
- The study assessed knowledge acquisition among the multidisciplinary team (MDT).
- Feedback was collected on the training's content, format, and delivery.
Main Results:
- A statistically significant improvement in median knowledge scores was observed, increasing from 2.5 to 4 out of 5 (p < 0.001).
- Participants reported a positive learning experience.
- The education program effectively enhanced staff understanding of BIA.
Conclusions:
- The neonatal education package successfully improved knowledge regarding BIA.
- The training was positively received and is suitable for adoption by other centers.
- This educational model can be adapted for introducing new technologies in intensive care settings.
