About this study

The primary purpose of this study was to evaluate the accuracy of gestational age (GA) estimates by using the New Ballard Score (NBS) in newborns 24 to 27 weeks GA with accurate obstetric estimates of GA. Secondary purposes were: (1) to compare the accuracy of GA estimates derived from the NBS, the original Ballard score, and the physical items of the original Ballard score and (2) to compare these measures of GA and best obstetric estimates of GA as predictors of survival, morbidity, and hospital stay among infants <28 weeks' gestation and among very low birth weight infants in general.

Read the detailed description

The Ballard maturational assessment is commonly used to estimate gestational age (GA) when the menstrual history and other obstetrical estimates of GA are uncertain. The original Ballard Score and the New Ballard Score are based on the assumption that the fetal skin, subcutaneous tissues, and neuromuscular system mature at predictable rates.

Because of variation in maturation rates among healthy fetuses or abnormalities of fetal development, fetal maturation can vary at a given GA. For very premature infants, small differences in GA result in large differences in outcome and may even determine whether intensive care is given.

The primary purpose of this study was to evaluate the accuracy of GA estimates by using the NBS in newborns 24 to 27 weeks GA with accurate obstetric estimates of GA. Secondary purposes were: (1) to compare the accuracy of GA estimates derived from the NBS, the original Ballard score, and the physical items of the original Ballard score and (2) to compare these measures of GA and best obstetric estimates of GA as predictors of survival, morbidity, and hospital stay among infants <28 weeks' gestation and among very low birth weight infants in general.

For this study, eligible infants included those with birth weights of 401-1500g born in the National Institute of Child and Human Development (NICHD) Neonatal Research Network (NRN). Before 48 hours of age, enrolled infants were examined using the New Ballard Score by trained and certified research nurses masked to obstetric estimates of gestational age. A best obstetrical estimate of GA, used for screening of potentially eligible infants, was determined from the last menstrual period, obstetrical measures, and ultrasound findings recorded on the labor and delivery records.

Questions about this trial

What is this clinical trial studying?

An observational study of Infant, Newborn and Infant, Low Birth Weight, run by NICHD Neonatal Research Network at 11 sites in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 8 inclusion and 1 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 8 Jun 2015. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 11 sites in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT01203449, which also lists 1 linked publication.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 8 Jun 2015.
