Breastfeeding Evaluation Indicators System is a Promising Evaluation Tool for Preterm Infants in Neonatal Intensive Care Units (NICUs)

Background: Breast feeding can enhance preterm infants' neurodevelopmental outcome, regulate immune function development. This study aims to develop breastfeeding evaluation indicators system in neonatal intensive care units (NICU) and to provide theoretical basis for all-round evaluation of breast feeding quality for hospitalized preterm infants. Material/Methods: This study was performed based on Avedis Donabedian's theory of medical care quality. Preterm infant breast feeding evaluation indicators system frame was initially formed by using literature review, clinical on-spot observation and expert consultation methods. By using specialists meeting method and Delphi method, evaluation indicators system for preterm infants breastfeeding was verified and established. Breastfeeding evaluation indicators system were performed in NICU of hospitals in Binzhou and Shanghai. Feasibility and usability of indicators system were examined. Results: Breastfeeding evaluation indicators system for preterm infants comprise 3 levels, including level 1 (3 indicators), level 2 (7 indicators), and level 3 (18 indicators). Recognition rates of importance for level 2 and 3 range from 94.4% to 100.0% and 80.6% to 100.0%, respectively. Mean of Likert rating for level 2 and 3 range from 3.31 to 3.89 and 3.03 to 3.97, which are all higher than the average value of 2.50. Kendall's coefficient and its significance test showed that consistency of experts' opinion for indicators' importance is high (P<0.001). This strategy of combining qualitative and quantitative methods could be used in overall evaluation of the breastfeeding quality in NICUs. Conclusions: Indicators system is feasible and is a promising evaluation tool for continuously improving breastfeeding quality for preterm infants in NICUs.
