The two-day treatment gap between in-center hemodialysis patients is associated with more hospital admissions and an increased mortality rate, according to a report published in Kidney International.

Researchers looked at 5,800 hemodialysis patients in Sheffield, United Kingdom. They found that hospitalization was more likely for patients who had a 2-day interval between treatments than those with a 1-day interval. Health officials attributed this to a build-up of fluid and toxins. The study also offered potential solutions, such as more frequent dialysis treatments and a lower fluid removal goal.
