Why might crude death rates be misleading?
What is SMR? Can SMR of one population be compared to SMR of another population? In the indirect method, what data from the reference (standard) population is used?
Homework Answers
1) Crude death rates might be misleading because it doesn't take into account age or sex difference among the population which has an important effect on many health outcomes such as mortality,heart disease ,Cancer , infectious diseases and injury .
2) SMR(Standardized Mortality Ratio) :- It is the ratio of observed deaths in the study group to expected deaths in the general population.This ratio can also be expressed as a percentage simply by multiplying by 100.
3)SMR of one population can't be compared with SMR of another population because they are calculated using different weighting schemes that depend upon the age structures of the index/ study population.SMR can however be compared if we make the assumption that the ratio of rates between index and reference population is constant.
4) In indirect method ,age/sex specific mortality rates data from reference (Standard)population is used.

The one situation where an entire, closed population was tested was the Diamond Princess cruise ship and its quarantine passengers. The case fatality rate there was 1.0%, but this was a largely elderly population, in which the death rate from Covid-19 is much higher. Projecting the Diamond Princess mortality rate onto the age structure of the U.S. population, the death rate among people infected with Covid-19 would be 0.125%. But since this estimate is based on extremely thin data —...

Epidemiologists are concerned with population growth as it relates to potential healthcare issues. Why do rates and measures of population change use the “total mid-year population” instead of the “end-of-year population?” What makes one measurement more effective than the other? Choose a real or a hypothetical example to explain how using the “end-of-year population” affects data collection and outcomes. Compose an essay addressing the topics above. You must format your paper in accordance with APA guidelines. It should be 3...

Define cost smoothing, and describe the consequences it can have on costs. What is cost smoothing? A. Cost smoothing describes a costing approach that allocates indirect costs to cost objects based on the budgeted average indirect cost rates multiplied by the budgeted quantities of the cost allocation bases. B. Cost smoothing describes the method of calculating the average fixed manufacturing overhead cost of each unit produced or service performed. C. Cost smoothing describes a costing system that uses direct costs...
