Background: Preterm birth is an important health concern in countries with limited resources and healthcare access. Topical therapy may be effective for improving outcomes in preterm neonates whose skin barriers are compromised due to immaturity. Objectives: To systematically review the topical VCO's effects in preterm infants on infection, mortality, and dermal maturity. Methodology: Systematic review and meta-analysis of RCTs of topical VCO in preterm infants were conducted. Databases included PubMed, Google Scholar, Clinical trials.gov, Trip, Cochrane Library, and HERDIN. The risk of bias was assessed by two authors independently. RR with 95% CI was used for the pooled estimate of dichotomous outcomes including infection prevention, mortality reduction, and skin irritation. Mean differences with 95% CI were used for the pooled estimate of weight loss and NSCS. Results: Of 110 records identified, 3 RCTs with 2440 patients were included. Prevention of infection had a trend toward VCO (RR = 0.90, [95% CI: 0.64, 1.27] while the results for mortality reduction were inconclusive (RR = 0.45, [95% CI: 0.06, 3.38]. NSC scores showed a beneficial trend toward VCO (RR = -0.03, [95% CI: -0.16, 0.09]. Both secondary outcomes of skin irritation and weight loss had inconclusive results. Conclusions This review showed the lack of evidence of the effectiveness of topical VCO in improving various outcomes in premature infants. The effects on infection prevention and dermal maturation were favorable. However, its effects on preventing mortality, skin irritation, and weight loss were inconclusive.
