Audit of survival after premature birth

Area of Science:

• Neonatal Medicine
• Perinatology
• Pediatric Survival Statistics

Background:

• Accurate prognosis data for neonates is essential for parental counseling and healthcare resource allocation.
• Local data is particularly important due to variations in care and outcomes across different settings.
• Premature infants, especially those born before 32 weeks gestational age, represent a vulnerable population requiring specific prognostic information.

Purpose of the Study:

• To present local data on the survival rates of infants born before 32 weeks gestational age.
• To provide data for counseling families of premature infants.
• To inform departmental resource allocation strategies based on observed neonatal outcomes.

Main Methods:

• Retrospective analysis of survival to discharge data for infants born below 32 weeks gestational age.
• Data collected over a one-year period from a single clinical unit.
• Calculation of mortality rates per thousand live births for specific gestational age ranges (26-31 weeks).

Main Results:

• No infants born below 26 weeks gestational age survived to discharge.
• Mortality rates per thousand live births were: 875 at 26 weeks, 500 at 27 weeks, 500 at 28 weeks, 615 at 29 weeks, 158 at 30 weeks, and 105 at 31 weeks.
• Significant variation in survival rates observed across different gestational ages within the <32 weeks group.

Conclusions:

• Local survival data for extremely premature infants is vital for accurate prognostication and resource management.
• The study highlights the critical impact of gestational age on neonatal survival outcomes.
• Challenges in data interpretation within a specific clinical setting necessitate careful consideration of local factors.
