Insights
International academic service-learning improved feeding and oral care for medically complex children in Guatemala. Staff showed significant gains in knowledge and technique, enhancing care quality.
Area of Science:
- Medical Education
- Pediatric Care
- Global Health Initiatives
Background:
- Children with medical complexities and special needs often require specialized feeding and oral care.
- Medical staff in resource-limited settings may lack targeted training in managing these complex needs.
- International academic service-learning offers a framework for sustainable capacity building.
Purpose of the Study:
- To evaluate a long-term international academic service-learning (I-ASL) intervention.
- To enhance the swallowing, feeding, and oral care techniques of medical staff.
- To improve care for medically complex children with special needs in a Guatemalan orphanage.
Main Methods:
- Utilized the PRECEDE-PROCEED model for program framework and evaluation.
- Focused on five key areas: knowledge, skills, equipment, technique, positioning, and communication.
- Delivered a five-day intervention including verbal instruction, modeling, and small group training.
Main Results:
- Demonstrated statistically significant improvements in staff knowledge regarding feeding and oral care.
- Showcased significant increases in the application of appropriate feeding and oral care techniques.
- Observed enhanced skills in positioning and communication related to patient care.
Conclusions:
- The I-ASL intervention successfully enhanced the skills and knowledge of medical staff.
- The program fostered a strong, collaborative relationship between the I-ASL team and the host organization.
- This model demonstrates potential for improving care for vulnerable pediatric populations globally.
Purpose:
The purpose of this study was to evaluate a long-term on-going international academic service-learning (I-ASL) intervention. Its goal was to improve swallowing, feeding and oral care technique of medical staff in an orphanage in Guatemala to children who are medically complex and have special needs.
Method:
The PRECEDE-PROCEED model was used as the conceptual framework of the program. Five major target areas were identified during the diagnosis, assessment, implementation and evaluation phases of the model: knowledge and skills, feeding equipment, feeding and oral care technique, positioning and communication. Verbal instruction, modelling and small group training was provided by the research team across all visits. A five-day intervention designed to increase feeders' knowledge of feeding and oral care technique, signs and symptoms and complications of dysphagia and to improve their feeding, positioning and oral care technique was implemented and evaluated.
Result:
Statistical analyses showed significant increases in knowledge and appropriate feeding, positioning and oral care technique.
Conclusion:
As a consequence of the intervention, a trusting and mutually supportive relationship was built between the I-ASL team and the host organization.
