Adult malaria mortality during 2019 at Bo Government Hospital, Sierra Leone.

It is uncertain whether malaria is an important cause of death among adults in endemic areas. We performed a chart review of adults admitted to Bo Government Hospital during 2019. Of 893 admissions, 149 (59% female, mean age 58.5 years) had a laboratory diagnosis of malaria and 22 (14.8%) died. Mortality was significantly higher among patients with severe malaria compared with those who had non-severe malaria (6/20 [30%] versus 16/129 [12.4%], p =0.031).  Our results suggest that malaria is a common cause of death in hospitalized Sierra Leonian adults.
