University Of Washington Models Predict 72,433 Total Deaths By August

How many people are likely to die in the United States of Covid-19? How many hospital beds is the country going to need? When will case numbers peak? To answer those questions, many hospital planners, media outlets, and government bodies — including the White House — relied heavily on one particular model out of the many that have been published in the past two months: the University of Washington’s Institute for Health Metrics and Evaluation (IHME).

The model first estimated in late March that there’d be fewer than 161,000 deaths total in the US; in early April, it revised its projections to say the total death toll through August was “projected to be 60,415” (though it acknowledged the range could be between 31,221 and 126,703). The model has been cited often by the White House and has informed its policymaking. But it may have led the administration astray: The IHME has consistently forecast many fewer deaths than most other models, largely because the IHME model projects that deaths will decline rapidly after the peak — an assumption that has not been borne out.

On Wednesday, the US death count passed the 60,000 mark that the IHME model had said was the likely total cumulative death toll. The IHME on April 29 released a new update raising its estimates for total deaths to 72,433, but that, too, looks likely to be proved an underestimate as soon as next week. Even its upper bound on deaths — now listed as 114,228 by August — is questionable, as some other models expect the US will hit that milestone by the end of May, and most project it will in June.
