Years of Potential Life Lost (YPPL)
Years of Potential Life Lost (YPPL) (/ji:ərz ɒv pəˈtenʃəl laɪf lɒst/), is a measure of the premature mortality or early death. It is an estimate of the average years a person would have lived if he or she had not died prematurely.
Etymology
The term "Years of Potential Life Lost" is derived from the concept of potential years of life, which refers to the years a person has left to live based on statistical averages. The term "lost" is added to indicate the years that are lost due to premature death.
Definition
YPPL is calculated by subtracting the age at death from a predetermined end point age, often set at 75 years. This measure is used in public health, epidemiology, and healthcare planning to identify and prioritize preventable causes of death.
Calculation
The calculation of YPPL involves the following steps:
- Identify the cause of death.
- Determine the age at death.
- Subtract the age at death from the predetermined end point age (usually 75 years).
The result is the number of years of potential life lost.
