Question:

1). An epidemiologic survey of Motor Vehicle Accidents (MVA) in Metroville, a city with a population of 100,000 (during the midpoint of the year), produced the following data for a particular year:

Number of drivers in Metroville during any given month

12,000

Total number of residents injured from MVA

1,800

Total number of deaths from MVA

90

Total number of deaths from all causes

900

The cause-specific mortality rate from using motor vehicles was: (Please provide the step by step work).

Number of drivers in Metroville during any given month

12,000

Total number of residents injured from MVA

1,800

Total number of deaths from MVA

90

Total number of deaths from all causes

900

Explanation / Answer

The cause-specific mortality rate is the mortality rate from a specified cause for a population. The numerator is the number of deaths attributed to a specific cause. The denominator remains the size of the population at the midpoint of the time period. The fraction is usually expressed per 100,000 population.

Therefore the cause specific mortality rate in above case is 90/1,00,000 *100000=90

i.e. Cause specific mortality rate = (Number of deaths assigned to a specific cause during a given time interval) / (Mid-interval population) = 90/100000*100000=90
