Givens: Diabetes case (DM) in service area
1. CDC showed Prevalence rate for DM is 10.7 per 1,000 population and 5-year annual mean incidence rate for DM is 7.9 per 1,000. Calculate the estimate no. of persons with DM in the targeted service area in the previous year.
2. There are at least ten hospital in area treating 7,060 DM patients. hosptial A's Market share for DM treatment is 6.66%.
a. How many patients with DM were treated at Hospital A in the previous year?
b. assume no changes in market share, est how many patients with Dm coulf potentially have been treated at Hospital A the previous year?
c. Assuming no change in market share, no deaths among paitent in population with DM, and static growth in the pop of Hospital A service area, est how many pateints with DM can be expected to be treated at Hosptial A the following year?

Answer to question# 1)
The total population of target area is: 1271755
The prevalence rate = 10.7 per thousand = 0.0107
Thus total prevalant cases = 1271755 * 0.0107 = 13607.7785 ~ 13608
The incident rate = 7.9 per 1000 = 0.0079
Thus total new cases = 1271755 * 0.0079 = 10046.8645 = 10047
.
total number of cases to be treated = 13608 + 10047 = 23655
