mortality rate

mortality rate

# ppl who die of disease/anyone at risk of dying due to illness (including those who do not have disease)

Proportionate mortality

(# deaths specific cause in defined pop @ specific time/total # deaths in defined pop @ specific time) X 100 = proportionate mortality

Case fatality rate

(# ppl dying during time frame after onset or diagnosis/# ppl w disease) X 100 = % Case Fatality

Mortality rate all causes

(total # deaths due to all causes in 1 year/# ppl in population at mid-year) X 1,000 = mortality rate

most important predictor of mortality

age

Mortality is good for

High fatality rate Duration of disease, survival, is short.

Quality of Life Measurement

Impact of disease on afflicted individuals above and beyond mortality.

Mortality rate vs. Case fatality rate

Mortality denominator represents all at risk of dying. Case Fatality denominator limited to those who already have disease.

Disablility-adjusted life year

Years of life lost to pre-mature death & years lived w/ a disability of specified duration and severity.

YPLL

Years potential life lost Expected age =75 death at 50 YPLL= 75-50= 25
