Quantitative health impact assessments of chronic mortality,where the
impacts are expected to be observed over a numberof years, are complicated
by the link between death rates andsurviving populations. A general calculation
framework for quantitativeimpact assessment is presented, based on standard
life tablecalculation methods, which permits consistent future projectionsof
impacts on mortality from changes in death rates. Implementedas a series
of linked spreadsheets, the framework offers completeflexibility in the
sex specific, age specific, and year specificpatterns of baseline mortality
death rates; in the predictedimpacts upon these; in the weights or values
placed on gainsin life; and in the summary measures of impact. Impacts
canbe differential by cause of death. Some examples are given ofpredictions
of the impacts of reductions in chronic mortalityin the populations of
England and Wales and of Scotland.
