 The vast majority of UK neonatal units, 70 of 161, 44 percent, currently routinely administer probiotics to preterm infants. Most of these units, 64 of 70, 91 percent, have guidelines available and most, 59 of 70, 84 percent, require enteral feeding before commencing probiotics. Additionally, 69 of 70, 99 percent, units would stop probiotics if the infant was diagnosed with necrotizing enterocolitis and 57 of 70, 81 percent, would also stop if enteral feeds were withdrawn. Furthermore, 24 of 91, 26 percent, units that do not currently use probiotics plan on introducing them within the next year.
