Summary
Radiographs for neonatal long lines show poor reliability in tip visualization and placement assessment. Perceived location, not accuracy, often determined repositioning actions.
Area of Science:
- Neonatal Imaging
- Medical Device Placement
- Radiographic Interpretation
Background:
- Accurate placement of neonatal long lines is critical for effective treatment delivery.
- Radiographs are commonly used to confirm the position of these lines.
- Variability in interpretation can lead to suboptimal patient care.
Purpose of the Study:
- To evaluate the intra- and interobserver variability in interpreting neonatal long line tip positions on radiographs.
- To assess the actions taken based on radiographic interpretations.
Main Methods:
- Digitized radiographs of neonatal long lines were reviewed online by medical professionals.
- Participants identified line tip visibility, anatomical position, and recommended action.
- Interobserver and intraobserver agreement were statistically analyzed.
Main Results:
- Only 50% of interpretations identified the long line tips.
- The right atrium was the most frequently reported position (31%).
- Intraobserver variability showed 27% disagreement on tip visualization.
Conclusions:
- Radiographic assessment of neonatal long line tips demonstrates poor inter- and intraobserver reliability.
- Perceived line tip location significantly influenced decisions regarding repositioning.
