The meaning and use of the cumulative rate of potential life lost.
Background The'years of potential life lost' (YPLL) is a public health measure in widespread use.
However, the index does not apply to the comparisons between different populations or across different time periods.
It also has the limit of being cross-sectional in nature, quantifying current burden but not future impact on society.
Methods A new years-lost index is proposed-the'cumulative rate of potential life lost' (CRPLL).
It is a simple combination of the'cumulative rate' (CR) and the YPLL.
Vital statistics in Taiwan are used for demonstration and comparison of the new index with existing health-status measures.
Results The CRPLL serves the purpose of between-group comparison.
It can also be considered a projection of future impact, under the assumption that the age-specific mortality rates in the current year prevail.
For a rare cause of death, it can be interpreted as the expected years (days) of potential life lost during a subject's lifetime.
Conclusions The CRPLL has several desirable properties, rendering it a promising alternative for quantifying health status.
