Abstract
Aim:
This study examined the predictors of suboptimal interdialytic weight gain among haemodialysis patients.
Method:
A cross-sectional study was conducted among haemodialysis patients from five dialysis units affiliated to a large metropolitan hospital in Melbourne, Australia. Demographic and clinical data were collected from electronic medical records. Interdialytic weight gain was calculated from a midweek run. Regression analysis were performed to determine factors associated with suboptimal interdialytic weight gain
Results:
A total of 269 patients (62% female) with a mean (SD) age of 65.8 (14.8) years participated. Sixty percent were from culturally and linguistically diverse background (CALD) and 44% had severe comorbidity status based on the Charlson Comorbidity Index. With respect to socioeconomic status, 114 (42.4%), 65 (24.1%) and 90 (33.5%) of patients belonged to the most disadvantaged, intermediate and most advantaged groups respectively. The mean (SD) absolute and relative IDWG was 1.68 (0.97) kilograms and 2.17 (1.34) % respectively. The relative IDWG for patients from CALD backgrounds was 43% higher compared to those from non-CALD background and patients who dialysed with arteriovenous fistulas had higher relative IDWG compared to those who had other forms of access. Base weight was negatively correlated to relative weight gain (all p values in adjusted analyses <0.05).
Conclusion:
Among patients on hemodialysis, being from CALD background and dialysing with an access other than an arteriovenous fistula was associated with higher relative IDWG derived from a midweek run. Identifying these factors will inform the timely implementation of interventions targeted at subgroups who experience suboptimal IDWG such as those from CALD backgrounds .
