Many Preterm Babies Still Exposed to Early Antibiotics

Antibiotics given to protect preterm babies come with potential risks. Unnecessary early antibiotic therapy for preterm babies can be avoided if clinicians have specific guidelines.

Most preterm babies, who are at risk for sepsis but who may not have a culture confirmation of infection, are on antibiotic therapy in the first few days of life, a new study found.

Findings of the study suggest neonatal antibiotic stewardship efforts are needed to help clinicians identify infants at lowest risk for infection to avoid unnecessary antibiotic exposure.

Antibiotics - Use and Abuse
Antibiotics are among the most used and abused medications. This article explains some general features about antibiotics.

Why the Research is Interesting

Antibiotics are commonly used in neonatal intensive care units. Empirical (early, without culture confirmation) antibiotic therapy is frequently given to very low-birth-weight (less than 1,500 grams) infants when they are born because of their risk for sepsis combined with the clinical instability of premature infants. Previous studies suggest these antibiotics given to protect infants also are associated with potential risks.

Who and When

Interaction of Antibiotics with Dairy Products
Antibiotics like tetracyclines and fluoroquinolones used in the treatment of bacterial infections interact mainly with dairy products and lead to adverse side effects.

40,364 very low-birth-weight infants, including 12,947 extremely low-birth-weight infants (less than 1,000 grams), who survived for at least a day at 297 hospitals between 2009-2015; the study used an administrative database

What and When (Study Measures)

Natural Antibiotics to Fight Bacterial Infections
Fighting infections the natural way and preventing them is always more effective than consuming medicines and antibiotics to treat them.

Antibiotics initiated within the first 3 days of age and subsequent antibiotics given for more than five days (exposures); trends over time in early antibiotic initiation and duration from 2009-2015.

Study Design
This was an observational study by Dustin D. Flannery, D.O., of Children's Hospital of Philadelphia, and coauthors. Researchers were not intervening for purposes of the study and they cannot control natural differences that could explain study findings.

Top 10 Alarming Risks of Low Birthweight in Babies
Low birthweight is a term given to babies who weigh less than 2,500 grams at birth. These babies look much smaller than babies with normal birthweight.

Result of the study

The majority of premature infants had early antibiotic initiation (78.6 percent of very low-birth-weight infants and 87 percent of extremely low-birth-weight infants) and rates of initiation of empirical early antibiotic therapy didn't change over time.

Study Limitations
The database didn't have information to compare the severity of infants' early illness or information to identify infants with culture-confirmed infections; hospitals in the southern United States were over represented.
