This study investigated the mortality risk among patients requiring maintenance dialysis in the 30 days following a hurricane. The researchers followed patients registered in the United States Renal Data System who initiated treatment between 1997 and 2017 in hurricane-afflicted counties. Hurricane exposure was determined as a tropical cyclone event with peak local wind speeds of 64 knots in the county of a patient's residence.
The study found that hurricane exposure was associated with a significantly higher mortality risk in patients requiring maintenance dialysis, even after adjusting for demographic and socioeconomic factors. Overall, the study suggests that patients requiring maintenance dialysis should receive extra attention during and after hurricanes to mitigate their mortality risk.
