Preterm oral feeding scale to assist in deciding initial oral feeding of preterm infants in neonatal intensive care units.

Background: The inconsistency in decisions to commence oral feeding indicates that health professionals require clearer guidelines to determine when to initiate oral feeding in preterm infants. This study applied the Taiwan version of Preterm Oral Feeding Readiness Assessment Scale (TW-POFRAS) to clinical decision-making, especially for preterm infants with a birth weight less than 1,500 g or gestational age (GA) less than 32 weeks.

Methods: This was a single-center observational cross-sectional study and 81 preterm infants were recruited. Lengths of stay from admission to initial one-meal oral feeding, to one-day all-meal oral feeding, and to discharge were analyzed. Scale scores, physician orders, and smooth oral intake of 5 mL of milk were analyzed. Kappa coefficients were examined to determine concordances within the results.

Results: At least moderate concordance was evident (k = 0.492). Most preterm infants can begin to consume one meal of the least 5 mL of milk smoothly and proceed to consume a full day of meals with a week; they are typically discharged from the hospital within a month, except for those with a birth weight less than 1,500 g or a GA less than 32 weeks. For 17 of 81 participants, assessment results for physician orders, 5-mL milk consumption, and scale scores were inconsistent. Participants with a birth weight less than 1,500 g or GA less than 32 weeks were able to meet the 5-mL standard by the postmenstrual age of 35 weeks, at latest.

Conclusion: We recommend that TW-POFRAS should be used in conjunction with physicians' clinical decision-making for oral feeding readiness for preterm infants in the NICU.
