Insights
The Oral FEeding Assessment in premaTure INfants (OFEATINg) scale is a validated tool for assessing preterm infants
Area of Science:
- Neonatal care
- Pediatric feeding
- Clinical assessment tools
Background:
- Neonatal units require tools to assess premature infants transitioning from gastric tube to oral feeding.
- Evaluating infant readiness for oral feeding is crucial for successful transition and development.
Purpose of the Study:
- To validate the Oral FEeding Assessment in premaTure INfants (OFEATINg) instrument.
- To assess the psychometric properties of the OFEATINg scale.
Main Methods:
- A psychometric validity and reliability study was conducted in Neonatal Intensive Care Units.
- Evaluated reliability, convergent, discriminant, and construct validity, sensitivity, and specificity.
- Analyzed 621 feedings from 56 preterm infants (31-35 weeks postconceptional age).
Main Results:
- Confirmatory factor analysis supported a 3-factor, 13-indicator model.
- Cronbach's alpha was 0.78, indicating good internal consistency.
- High inter-rater reliability was observed (Pearson 0.9, ICC 0.95).
Conclusions:
- The OFEATINg scale is a valid and reliable instrument for assessing oral feeding readiness in preterm infants.
- Clinicians can use OFEATINg to evaluate infant abilities and guide feeding transition decisions.
Abstract:
Professionals that work in neonatal units need to identify the strengths and weaknesses of the premature infant who is in the transition process from feeding through a gastric tube to oral feeding. The main aim of this study was to validate the Oral FEeding Assessment in premaTure INfants (OFEATINg) instrument. A psychometric validity and reliability study was conducted in Neonatal Intensive Care Units of two public, metropolitan, university hospitals. The study population were premature infants at a postconceptional age of 31-35 weeks. The study included evaluation of the reliability, convergent, discriminant and construct validity, sensitivity and specificity of the OFEATINg instrument. A total of 621 feedings of 56 preterm infants were evaluated. Confirmatory factor analysis identified 3 factors and 13 indicators with a good fit to the model. Cronbach's alpha coefficient was 0.78. The instrument showed high indices of inter-rater reliability (Pearson 0.9 and intraclass correlation coefficient 0.95). The OFEATINg scale is a valid and reliable instrument for evaluating the readiness for oral feeding of preterm infants. It may enable clinicians to evaluate the physiological and behavioral abilities involved in the oral feeding process and help them make decisions related to the transition to full oral feeding.Clinical trial registration: This study was prospectively registered at the two Institutional review boards.
