WORKSHEET #1 Your small community hospital serves an aging population that has needed diagnostic and treatment services for a variety of health conditions. The medical staff has asked for a report that details the incidence and prevalence rates for diabetes, cancer, and arthritis for the past 3 years. It is your responsibility to collect the information and calculate the rates for each. The mid-interval population for 2013 was 55,000, for 2014 it was 56,000, and for 2015 it was 55,000. 2013 2014 2015 Health Condition New Existing New Existing New Existing Diabetes 491 4,491 645 5,008 623 5,620 Cancer 212 6,844 198 6,719 376 7,421 Arthritis 624 9,456 565 10,548 776 9,747 1. To calculate an incidence rate, you will need to find the number of (new/existing) diseases for the period? 2. The denominator for the incidence rate is the 3. The constant for the incidence rate is usually at least population. 4. What number would be contained in the numerator for the incidence rate for cancer in 2013? 5. What number would be contained in the denominator for the incidence rate in 2013? 6. Using a constant of 1000, and rounding to a whole number, what is the incidence rate for cancer for this community in 2013?

While the incidence rate measures the of a disease in a population, the prevalence rate measures the public health burden of the disease in a population. 2. To calculate a prevalence rate, you need to add the new cases to the number of cases for the period. 3. The denominator of the prevalence rate is the. period. during that time 4. The number of new cases for diabetes in 2014 is cases are 5. The population for the area in 2014 was and the existing 6. The prevalence rate for diabetes in 2014, rounded to a whole number, is - per thousand people. 7. The diabetes prevalence rate means that for every thousand people, there are people with diabetes.

What is the incidence rate, rounded to a whole number, for arthritis in 2015? 2. What is the prevalence rate, rounded to a whole number, for arthritis in 2015? 3. The incidence rate for 2015 for arthritis is for the year, whereas the prevalence rate is thousand for the year. new cases per thousand existing cases per 4. If you wanted to compare the incidence of arthritis in women and men in your population, you would need to know the number of new cases in each sex as well as the number of men and women in the total population in 2015 for the
