Hypothesis: Fewer neonates managed using information from heart rate characteristics (HRC) will require intubation and mechanical ventilation as a result of sepsis and sepsis-like illness.

Infants will be randomly assigned to one of two groups. One group of infants will have the HRC index known to the physicians caring for them, and physicians will use the HRC index as they desire to aid in clinical management.

Infants in the other group will have the HRC index recorded, but this information will not be displayed to the physicians caring for the infants.

Primary Outcome Measures:
  • Number of Ventilator-free Days [ Time Frame: 120 days ]

Secondary Outcome Measures:
  • Duration of Hospital Stay [ Time Frame: 120 days ]
  • Days on Antibiotics [ Time Frame: 120 days ]
  • Mortality [ Time Frame: 120 days ]

Enrollment: 3003
Study Start Date: August 2005
Study Completion Date: May 2011
Primary Completion Date: February 2011 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: 1
Very low birth weight infants with their HRC index continuously displayed. Clinicians can utilize the HRC score to develop treatment plan.
Device: HeRO heart rate characteristics monitor
24 hour continuous HRC monitoring with display
No Intervention: 2
Very low birth weight infants for whom the HRC index is not displayed. Infants receive standard of care treatment.

Detailed Description:

Following randomization, infants will be managed as usual practice. The treating physicians of the HRC-display group will be able to utilize the HRC score to assist in the care of the infant. The physicians of the no-display group will provide care as per standard.

Clinical symptoms will be treated according to the medical discretion of each physician. Cultures will be obtained and antibiotics administered as per the medical discretion of the physicians.

Clinical, culture results, antibiotic administration, ventilator use, and outcome at 120 days data will be collected on the infants as well as their HRC score calculated by the HeRO heart rate characteristics monitor.
