More than 200 opioid overdose deaths likely went unreported in Michigan in 2015, according to a new University of Pittsburgh study.
Initial data said 1,186 people died from accidental opioid overdoses that year, according to the study. But a review by researchers showed that an additional 216 people likely died from unintentional opioid overdoses.
The undercount occurred because medical examiners and other health officials used incomplete data on death certificates. They didn't specify which type of drugs caused the overdose deaths. In order to be counted as an opioid overdose death, opioids need to be listed as the reason for the overdose.
The new numbers mean that in 2015, Michigan's death rate from unintentional opioid overdose was the 13th highest in the nation, with 14.13 deaths per 100,000 people. Old data had Michigan ranked 14
