Summary
Pediatric gastrointestinal foreign bodies have dynamic risk trajectories. Multidisciplinary team (MDT) involvement improves outcomes for high-risk cases, suggesting a shift from static to dynamic management strategies.
Area of Science:
- Pediatric Gastroenterology
- Clinical Risk Assessment
- Health Services Research
Background:
- Gastrointestinal foreign bodies in children present evolving risks.
- Conventional classification may miss progressive complications.
- Dynamic risk assessment is needed for pediatric foreign bodies.
Purpose of the Study:
- To characterize risk trajectories of pediatric gastrointestinal foreign bodies.
- To evaluate the impact of multidisciplinary team (MDT) involvement on adverse outcomes.
Main Methods:
- Explanatory sequential mixed-methods design with 198 pediatric cases.
- Latent class growth modeling for risk trajectory identification.
- Multivariable regression and critical incident technique for qualitative analysis.
Main Results:
- Four risk trajectories identified: stable low-risk (52%), slow progression (28%), sudden high-risk (12%), and occult perforation (8%).
- MDT involvement significantly improved outcomes for sudden high-risk (OR=3.87) and occult perforation (OR=5.67) trajectories.
- Qualitative analysis highlighted MDT's role in decision-making and outcome improvement.
Conclusions:
- Dynamic, trajectory-based monitoring is superior to static classification for pediatric gastrointestinal foreign bodies.
- MDT involvement is crucial for timely interventions at critical decision points.
- A risk monitoring framework with dynamic imaging can enhance clinical management.
