Drops of Colostrum, Layers of Evidence: A Synthesis on Oropharyngeal Colostrum for Preterm Infants
The Question and the Practice
In a composite 40-bed level III neonatal intensive care unit, some nurses swab the inside of a preterm baby's cheeks with drops of the mother's colostrum in the first days of life, while others do not, because the unit has no policy. Colostrum is rich in immune factors, and the practice aims to deliver them to the oral lining of babies who are too small or sick to feed. The question for this synthesis is: in preterm infants born before 32 weeks (P), does oropharyngeal colostrum in the first week (I), compared with no colostrum or placebo (C), reduce sepsis, necrotizing enterocolitis and death (O) before hospital discharge (T)?
The Sources
Four sources, appraised in earlier modules, form the evidence base. A Cochrane review included six small randomized trials with 335 infants (Nasuf et al., 2018). A later systematic review pooled 17 randomized trials of colostrum or mother's own milk applied to the mouth (Kumar et al., 2023). A third review included 21 randomized trials with 2,393 infants and focused on sepsis and mortality (Anne et al., 2024). Finally, a Brazilian clinical trial compared 138 very low birth weight infants given colostrum with infants treated before the practice began, a nonrandomized design with historical controls (Martins et al., 2024).
Findings by Outcome
The table below arranges the main findings by outcome so that agreement and conflict are visible.
Table 1
Synthesis of Findings by Outcome
| Outcome | Nasuf et al. (2018) | Kumar et al. (2023) | Anne et al. (2024) | Martins et al. (2024) |
|---|---|---|---|---|
| Sepsis | No significant difference; very low quality | Reduced; low to very low certainty | Culture-proven sepsis reduced; high certainty | Not the focus |
| Necrotizing enterocolitis | No significant difference | Any stage reduced; stage 2 or higher not significant | Reduced; moderate certainty | Not the focus |
| Death before discharge | No significant difference | No significant difference | Reduced; high certainty | Reduced compared with historical controls |
| Time to full feeds | About 2.6 days sooner | About 1.75 days sooner | Sooner; low certainty | Not reported in abstract |
| Harms | None identified; data limited | None significant | No reduction in other morbidities; no harms reported | Not reported |
What the Evidence Shows Together
Across all four sources, one finding is consistent: babies who received oropharyngeal colostrum reached full enteral feeds sooner, by roughly two days. For sepsis and necrotizing enterocolitis, the direction of effect favors colostrum in every source, but statistical significance and certainty change over time. The Cochrane review found no significant differences, the 2023 review found reductions in sepsis and any-stage necrotizing enterocolitis with low certainty, and the 2024 review found reductions in culture-proven sepsis, necrotizing enterocolitis and death, rating certainty as high for sepsis and death. The nonrandomized trial reported a large reduction in mortality, but comparing babies with those treated in an earlier period cannot separate the effect of colostrum from other improvements in care over time, so it adds little weight. Taken together, the evidence has moved from no detectable effect to a probable benefit, and every source agrees that the practice appears safe.
Why the Reviews Disagree
The disagreement is best explained by the growth of the evidence rather than by error. The Cochrane review searched literature available up to 2018 and found only six small trials with 335 infants, too few events to detect differences in outcomes such as death. By 2023, 21 trials with more than 2,000 infants were available, giving far more statistical power. The reviews also differ in scope: one included mother's own milk as well as colostrum, and another focused on culture-proven sepsis. Certainty ratings differ as well; the 2024 review rated its sepsis and mortality findings as high certainty while the 2023 review rated similar findings as low, which suggests that judgments about bias in the included trials are not settled. Both newer reviews share authors, so they are not fully independent. The newer reviews also note that few extremely preterm infants were included, which limits confidence for the smallest babies (Anne et al., 2024).
Certainty, Benefit, Cost and Risk
Overall, the evidence is moderate in certainty: consistent in direction, supported by many randomized trials, but limited by small studies, variable quality and incomplete data for the smallest infants. Against that uncertainty stand three practical facts. The intervention uses the mother's own colostrum, which costs nothing and is already collected for later feeding. It carries no identified harms in any source. And it gives mothers a meaningful role in their baby's care in the first days, when many feel helpless. When benefit is probable, harm unlikely and cost negligible, moderate certainty is usually enough to support adopting a practice, while continuing to monitor outcomes.
Questions the Evidence Leaves Open
The synthesis also identifies questions the sources cannot yet answer. Protocols varied across trials in dose, frequency and duration, from every two hours to every three hours and from two days to a week or more, so the best regimen is unknown. Few trials reported whether mothers who took part expressed more milk or breastfed longer, although this is a plausible benefit of involving them early. None measured long-term development in a way that allows firm conclusions. And the effect in infants born before 28 weeks, who have the highest risk of sepsis and necrotizing enterocolitis, is the least certain. These gaps do not argue against adoption, but they shape how the unit should implement and monitor the practice.
Synthesis Statement
The body of evidence supports offering oropharyngeal colostrum to preterm infants born before 32 weeks, beginning in the first days of life and continuing through the first week, as a safe, low-cost practice that probably reduces sepsis and necrotizing enterocolitis, may reduce mortality and shortens the time to full feeds. It should be delivered by a standard protocol, with mothers supported to express colostrum early. Because evidence for extremely preterm infants is thinner, the unit should track outcomes for babies born before 28 weeks separately. The next module will plan how to implement this recommendation.
Conclusion
Synthesizing four sources shows how evidence on a simple practice can mature: early small trials found nothing definite, while larger pooled analyses now suggest real benefit. Organizing findings by outcome, explaining the disagreement, and weighing certainty against cost and risk produces a clear statement that the unit can act on.

How this NUR 506 Module 6 example is structured
Synthesis is organized by finding, not by source. After stating the question and the practice, the paper introduces the four sources briefly and then presents a table with outcomes down the side and sources across the top, which makes agreement and disagreement visible. The main discussion takes each outcome in turn. A separate section explains why an older review and newer ones disagree. The paper then judges overall certainty, weighs it against benefit, harm and cost, and ends with a synthesis statement the unit can take forward.

NUR 506 Module 6 questions, answered
What does a NUR 506 synthesis paper ask for?
A synthesis assignment typically asks what the body of evidence, taken together, supports: where studies agree, where they conflict and why, how strong the evidence is overall and what it means for practice. It is organized by themes or outcomes rather than by describing one study after another.
Why might two systematic reviews on the same question disagree?
Reviews can differ in search dates, inclusion criteria, which outcomes they pool and how they rate certainty. A newer review may include many trials published after an older one. Comparing these features usually explains the disagreement better than assuming one review is wrong.
What is oropharyngeal colostrum?
It is the practice of placing tiny amounts of a mother's colostrum, usually 0.1 to 0.2 milliliters, on the inside of a preterm baby's cheeks with a swab or syringe in the first days of life, often before the baby can be fed by mouth. The aim is immune protection through contact with the oral lining rather than nutrition.
