May 26, 2021- According to a study by researchers from UCLA, Northeastern University and the University of Utah, the largest increases were among Black Americans (50.3%) and Latinos (49.7%). Spikes were also most pronounced in low-income neighborhoods (46.4%) and in the five states — Alaska, California, Hawaii, Oregon and Washington — that border the Pacific Ocean (63.8%). Public health authorities had expected a sharp increase in overdoses during the pandemic because of the social isolation created by stay-at-home orders. The Centers for Disease Control and Prevention had previously published data on overdose deaths during the early stages of the pandemic, but those reports did not categorize statistics by race and ethnicity, neighborhood-level poverty rates and other relevant metrics, and they drew from data with a lag time of more than seven months. The researchers examined near-real-time data from about 90% of U.S. emergency medical service calls. The researchers write that the emergency medical service data they reviewed serves only as a proxy for actual total number of overdose deaths, so a deeper look at the data will be needed when the final statistics for 2020 are available.
