Answer #1

Mortality Rate are the death rates where as Morbidity Rates are the disease rates.

1. Mortality rates are often measured by the frequency of occurrence of death in a defined population during a specified interval. So this includes time, place and person.This means the prevalence of disease in certain place, among certain population during a specific time frame exactly gives the rates of the mortality.

2. Risk Adjusted Mortality Rate is that which is adjusted for prediction of risk of death.It is used to observe performance of some hospitals.

Risk Adjusted Mortality Rates = Observed Mortality Rates / Predicted Mortality Rates × Over all Mortality Rates.

Standardization of Mortality Rates : Death of a population can be adjusted to standard age i.e. a weighted average of the specific age related deaths in a specific population.

Standardized Mortality Rate = Observed deaths/ Expected deaths × 100

    Incidence and prevalence rates can also be used to compare the rates of disease across different settings (places), people, or time. We therefore need measures of comparison. The ratio of two measures of disease frequency is called the relative risk. The difference between two measures of disease frequency is called the risk difference, or rate difference. In some cases, it involves a measure in an exposed group (or groups) and a measure in an unexposed or comparison group. In other...
