Trial Outcomes & Findings for A Study of Neurophysiologically Based Occupational Therapy Intervention (NBOTI) for Feeding in the NCCU. (NCT NCT00766051)

NCT ID: NCT00766051

Last Updated: 2017-01-02

Results Overview

This outcome measured the number of days it took to go from all tube to all oral feeding or at discharge, whichever came first. Oral feeding percentages were based upon 150 kcal/kg/day. Feeding volumes and weights were taken directly from the nurses notes, and averaged daily. A two sample t-test was used to detect differences between the groups.

Participant Flow

12 infants were recruited for the study. Later, matched historical controls were utilized for comparison (Nov. 2007-March 2010).

There were no group assignments. This study was quasi-experimental as matched historical controls were utilized.

PRIMARY outcome

Timeframe: The time frame was from Baseline until all oral feeding or discharge, whichever came first (at or before 35 days).

Population: The intervention group and matched historical comparison group consisted of Four pairs of Extremely Preterm to Preterm infants with high risk factors, Three pairs of term or near term infants with Gastroschisis, Two pairs of infants term or near term with Omphalocele, and One pair of infants term age with Congenital Diaphragmatic Hernia.

This outcome measured the number of days it took to go from all tube to all oral feeding or at discharge, whichever came first. Oral feeding percentages were based upon 150 kcal/kg/day. Feeding volumes and weights were taken directly from the nurses notes, and averaged daily. A two sample t-test was used to detect differences between the groups.

SECONDARY outcome

Timeframe: The time frame was from Baseline until discharge (at or before 20 days).

Population: The intervention group consisted of Four Preterm infants with high risk factors, Three term or near term infants with Gastroschisis, and Two near term infants with Omphalocele. This outcome measured the correlation between the percentage of oral feedings and the percentage of High Frequesncy Heart Rate Variability.

Oral feeding percentage was based upon 150 kc/kg/day. Heart rate data was recorded about once per week during feeding using a Holter monitor connected to the bedside ecg. This data was downloaded in Cardiology, converted to numerical data as HRV by bioengineers at Politecnico di Milano, Italy. As infants reached 100% of oral feedings, heart rate variability data was analyzed to determine the infants' overall trend toward relaxation, measured as increasing High Frequency Percentage (HF %).

SECONDARY outcome

Timeframe: Upon an infant's entry into the study, and at discharge (at or less than 20 days).

Population: The intervention group consisted of Three Preterm infants with high risk factors, Three term or near term infants with Gastroschisis, Two near term infants with Omphalocele, and One near term infant Congenital Diaphragmatic Hernia.

The Global Confidence Scale of The Mother and Baby Scales (Wolke \[in Brazelton and Nugent\], 1995\]) is a total score measure of mother/parent self efficacy in the NICU as a result of training in NBOTI. It is a total score measure of the parent's perceived efficacy of themselves as confidence in the feeding, handling, caretaking, and interactions needed to foster relationships with their infants. An increase in this score denotes an increase in the parent's perception of their global confidence in caring for their infant. Global Confidence Measure uses a Likert scale. There are three questions, ranging from -3-3. The maximum score is 9, and the minimum score is -9.

SECONDARY outcome

Timeframe: Upon an infant's entry into the study, and again at discharge (at or less than 20 days).

Population: The intervention group consisted of Three Preterm infants with high risk factors, Three term or near term infants with Gastroschisis, Two near term infants with Omphalocele, and One near term infant Congenital Diaphragmatic Hernia.

The Easiness Scale measures the parent's perceived efficacy in the areas of infant irritability, sleeping habits, alertness and responsiveness, and difficulty. The Easiness Scale(Wolke \[in Brazelton and Nugent\], 1995\]) was used to determine mother/parent perceptions of their infants' mood and state in the NICU as a result of training in NBOTI. An increasing score denotes an improvement in parent efficacy in their perception of their infant's easiness.uses a Likert scale. There are four questions, ranging from -3-3. The maximum score is 12, and the minimum score is -12.
