Introduction Osteodystrophy management includes
dietary phosphorus restriction, which may limit
protein intake, exacerbate
malnutrition-
inflammation syndrome and mortality among
hemodialysis patients. Methods A multicenter randomized controlled trial was conducted in Lebanon, to test the hypothesis that intensive nutrition education focused on
phosphorus-to-
protein balance will improve patient outcomes. Six
hemodialysis units were randomly assigned to the trained hospital dietitian (THD) protocol (210 patients). Six others (184 patients) were divided equally according to the patients' dialysis shifts and assigned to Dedicated Dietitian (DD) and Control protocols. Patients in the THD group received nutrition education from hospital dietitians who were trained by the study team on renal dietetics, but had limited time for
hemodialysis patients. Patients in the DD group received individualized nutritional education on
dietary phosphorus and
protein management for 6 months (2-hour/patient/month) from study renal dietitians. Patients in the control group continued receiving routine care from hospital dietitians who had limited time for these patients and were blinded to the study. Serum
phosphorus (mmol/L),
malnutrition-
inflammation score (MIS), health-related quality of life (HRQOL) index and length of
hospital stay (LOS) were assessed at T0 (baseline), T1 (postintervention) and T2 (post6 month follow up). Findings Only the DD protocol significantly improved serum
phosphorus (T0:1.78 ± 0.5, T1:1.63 ± 0.46, T2:1.69 ± 0.53), 3 domains of the HRQOL and maintained MIS at T1, but this protective effect resolved at T2. The LOS significantly dropped for all groups. Discussion The presence of competent renal dietitians fully dedicated to
hemodialysis units was superior over the other protocols in temporarily improving patient outcomes.
