Perinatal Mortality Rate Calculation – Cost Calculator

Perinatal Mortality Rate (PMR) Calculator

Number of Stillbirths Fetal deaths occurring after 28 weeks of gestation.

Early Neonatal Deaths (0-7 Days) Number of deaths of live-born infants within the first 7 completed days of life.

Total Number of Births Sum of all live births and stillbirths in the same period.

Understanding the Perinatal Mortality Rate (PMR)

The Perinatal Mortality Rate (PMR) is a critical health indicator used to assess the quality of obstetric and neonatal care. It measures the number of stillbirths and early neonatal deaths (within the first seven days of life) relative to the total number of births.

The Perinatal Mortality Formula

To calculate the PMR, use the following standardized formula:

            PMR = [(Number of Stillbirths + Early Neonatal Deaths) / Total Births] × 1,000
        

Key Definitions

Stillbirths: According to the World Health Organization (WHO), for international comparisons, these are fetal deaths weighing at least 1,000g or occurring after 28 completed weeks of gestation.
Early Neonatal Deaths: Deaths of live-born infants occurring during the first seven completed days of life (0-6 days).
Total Births: This includes the total count of both live births and stillbirths.

Example Calculation

Suppose a regional hospital records the following data over one year:

Live Births: 2,450
Stillbirths: 30
Early Neonatal Deaths (0-7 days): 20

Step 1: Determine total births: 2,450 (live) + 30 (stillbirths) = 2,480 total births.

Step 2: Add deaths: 30 (stillbirths) + 20 (neonatal) = 50 perinatal deaths.

Step 3: Apply the formula: (50 / 2,480) × 1,000 = 20.16.

The Perinatal Mortality Rate for this facility is 20.16 deaths per 1,000 births.

Why is PMR Important?

PMR is used globally to evaluate maternal and child health programs. A high PMR often indicates issues such as:

Inadequate prenatal care and maternal nutrition.
Lack of skilled attendance during childbirth.
Poor access to emergency obstetric care.
Suboptimal neonatal resuscitation or post-natal care.

Public health officials use these metrics to allocate resources, improve clinical guidelines, and implement interventions aimed at reducing preventable infant mortality.
