1. What is Pregnancy Mortality Rate?

The Pregnancy Mortality Rate (PMR) measures the number of maternal deaths per 100,000 live births. It's a key indicator of maternal health and healthcare quality in a population.

2. How Does the Calculator Work?

The calculator uses the PMR formula:

Where:

• \( Maternal\ Deaths \) — Number of maternal deaths during pregnancy or within 42 days of termination
• \( Live\ Births \) — Number of live births in the same population and time period

Explanation: The ratio is multiplied by 100,000 to express the rate per standard population size for easier comparison.

3. Importance of PMR Calculation

Details: PMR is crucial for monitoring maternal health, evaluating healthcare systems, and identifying disparities in maternal care access and quality.

4. Using the Calculator

Tips: Enter the number of maternal deaths and live births from the same population and time period. Live births must be greater than zero.

5. Frequently Asked Questions (FAQ)

Q1: What counts as a maternal death?
A: Maternal death is defined as the death of a woman while pregnant or within 42 days of pregnancy termination from any cause related to or aggravated by the pregnancy.

Q2: What is considered a high PMR?
A: According to WHO, PMR above 300 is considered high, 100-299 is medium, and below 100 is low. Developed countries typically have PMR below 20.

Q3: How does PMR differ from maternal mortality ratio?
A: PMR is essentially the same as maternal mortality ratio (MMR), both expressing maternal deaths per 100,000 live births.

Q4: What time period should be used?
A: Typically calculated annually, but can be calculated for any time period as long as deaths and births cover the same period.

Q5: What are limitations of PMR?
A: PMR doesn't account for causes of death or quality of care. Small numbers can lead to unstable rates in small populations.
