Point Prevalence = number of cases/total number of persons
Here, the total population is 30,276, and the number of persons who developed hypertension is 17,620.
That is, the number of cases = 17,620 and the total number of persons = 30,276.
Hence,
Point Prevalence = number of cases/total number of persons
Point Prevalence = 17620/30276
Point Prevalence = 0.582
Point Prevalence = 58.2%
The point prevalence of hypertension among individuals who are prescribed drugs, after the drug’s first year on the market is 58.2%.
