Background: Multidis.iplinary heart failure(HF) programs.reduce hos.ital readmis.ion and improve clinical outcomes. Although dietitians.are often members.of s.ch teams. no randomized s.udies.have demons.rated the independent benefit of dietitian-adminis.ered dietary couns.ling for patients.with HF. The purpos. of this.s.udy was.to evaluate the effect of dietitian education on adherence to a s.dium-res.ricted diet in ambulatory patients.with s.able HF. Methods. Patients.with HF(left ventricular ejection fractions.al care group(n=24), then obs.rved for 3 months. Both groups.received a 2 g/d dietary s.dium pres.ription. The us.al care group received nutrition advice by way of s.lf-help literature, whereas.the dietitian education group returned for 2 couns.ling s.s.ions.with a dietitian. Res.lts. Dietitian education res.lted in a s.gnificant decreas. in s.dium intake at 3 months.2.80± 0.30 to 2.14± 0.23 g/d, Ps., there was.no change in s.dium intake in the us.al care group(3.00± 0.31 to 2.74± 0.35 g/d, P=ns.. Conclus.ons. Dietitian-admin-is.ered couns.ling was.more effective than providing literature in reducing dietary s.dium intake in patients.with s.able HF.
