Impact Of Nutrition Support On Clinical Outcome In Hospitalized Aging Patients At Nutritional Risk

Objective:According to the method of nutritional risk screening2002, we look at the impact of nutrition support for the patient at nutritional risk of aged inpatients on outcomeMethods:It is a prospective cohort study.2117patients from two departments (gastrointestinal department and neurological department) in Peking union medical college hospital and Beijing University third Hospital were recruited from May2011to April2012consecutively, nutritional risk screening tool and the close clinical observations were done by authors.. Data were collected from502patients with presumptive diagnosis and with the age over than60years old. According to the definitions of Infection events and hospital stay(LOS) were recorded by4tinmes a weekly follow-up until the patients were discharged.Results:Totally, there were2117patients recruited consecutively, including625older patients (Ages≥60).508old patients with presumptive diagnosis were included for the follow-op of infectious complications, in which60.6percent (302/502) patients had nutritional risk]。 Of the“at-risk”patients, the complication rate was significantly higher in the nutritional-support group than in the no-support group [8.7%(9/103) vs18.6%(37/199),P=0.019]. Subgroup analysis showed the complication rate was significantly higher in the parenteral nutrition support group[6.8%(5/73),P=0.02],but not in the enteral nutrition group [8.2%(1/22),P=0.059] when compared with the no-support group. Multivariate analysis showed nutritional support was a protective factor for complications in at-risk patients when adjusted for confounders [15(IQR11) v17(IQR10), P=0.096).].No significance difference in length of stay (Los)was found., but with trend.Conclusion:The findings showed that nutritional support was beneficial to the older patients at nutritional risk according to Nutritional Risk Screening2002by a lower complication rate.
