Final answer:
The case-fatality rate for opioid overdoses in Never-never Land is approximately 17.49%, calculated by dividing the number of overdose deaths by the estimated number of opioid addicts and then multiplying by 100.
Step-by-step explanation:
To calculate the case-fatality rate for opioid overdoses in Never-never Land, we need to consider the number of opioid overdose deaths and the estimated number of opioid addicts. The case-fatality rate is the percentage of people within a cohort who die from a specific condition, in this case, opioid overdose.
With 405 people dying from an overdose of opiates and an estimated 2,315 individuals addicted to opioids, the case-fatality rate can be calculated as follows:
Case-Fatality Rate = (Number of Deaths from Overdose / Number of Opioid Addicts) x 100
Case-Fatality Rate = (405 / 2,315) x 100 = 17.49%.
This rate indicates that out of all individuals with opioid addiction, approximately 17.49% died from an overdose. The opioid crisis has, unfortunately, resulted in a high number of fatalities among addicts, as shown in the increasing trend of opioid overdose deaths over the years.
