Heat Waves Take Deadly Toll on People
The research team which in addition to Brown also included scholars from Harvard University, Boston University and the organization Texas Prison Community Advocates combined data from the U.S. Bureau of Justice Statistics on mortality in Texas prisons with temperature data from NASA and used a novel epidemiologic analysis to arrive at its findings. The team reported that approximately 13% of mortality during warm months may be attributable to extreme in Texas prison facilities without air conditioning.
It is important to note that while an average of 14 people died each year from heat-related causes in Texas prisons without air conditioning, not a single heat-related death occurred in climate-controlled prisons, said lead study author Julie Skarha, who received her Ph.D. in epidemiology from Brown in June 2022.
“The majority of Texas prisons do not have universal air conditioning,” Skarha said. “And in these settings, we found a 30-fold increase in heat-related mortality when compared to estimates of heat-related mortality in the general U.S. population.”
Study co-author Dr. David Dosa, an associate professor of medicine, and health services, policy and practice at Brown, pointed out that heat is often a silent killer.
“We have seen similar situations in nursing homes, where heat isn’t reported on the death certificate,” said Dosa, a practicing geriatrician with dual appointments at the Providence V.A. Medical Center and Rhode Island Hospital. “It’s only after we run these analyses that we can determine how much of a role heat played in someone’s death.”
