Abstract:
Objective To summarize the progress of research on the influence of nutrition support on quality adjusted life year (QALY) in elderly patients with nutritional risk, and to evaluate the feasibility of QALY as an outcome indicator.Methods Literature in Chinese, English and Japanese relating to the feasibility of QALY and cost-utility in evaluating the influence of nutrition support on the outcomes of patients with nutritional risk published from 1980 to 2013 were searched in Wanfang, China National Knowledge Infrastructure,PubMed, Nature databases.The methodological quality of randomized controlled trials was assessed using Jadad scale combined with Schulz allocation concealment, and the quality of cohort studies with Newcastle-Ottawa scale.Results Totally 10 articles were fotnd, in which 8 were selected, including 6 randomized controlled trial and 2 cohort studies, covering 1 130 patients;the other 2 were excluded for not conforming to inclusion criteria.Four of the 6 randomized controlled trial indicate that QALY is higher and all-cost is lower in the treatment group compared with the control group (or cost-utility is higher in the treatment group).The 2 cohort studies indicate that total parenteral nutrition support at home could improve the QALY of malnourished patients and could save cost compared with nutrition support at hospital when necessary.Conclusions Nutrition support for patients with nutritional risk can improve prognosis, reduce cost, and increase QALY.More large-scale, high-quality randomized controlled trials are needed to evaluate the effect of nutrition support on the QALY of elderly patients with nutritional risk.
