This retrospective study describes patterns of interdialytic weight gain (IWG) over the first year of hemodialysis in 27 individuals. IWG increased over the first 12 weeks and appeared to reverse after 12 weeks, increasing again after 32 weeks. Interventions may need to occur after the individual has been receiving treatment for 12 weeks; booster interventions may be indicated after 32 weeks. Variability in the two measures used (mean daily interdialytic weight gain and mean daily percent above dry weight) suggests a need for further study.
