The impact of energy and protein intake on rehabilitation efficiency in convalescent patients.

Background and objectives: It is well known that more than 40% of patients in the convalescent rehabilitation settings suffer from malnutrition, and that appropriate nutrition management can improve rehabilitation outcomes.

Methods and study design: In this study, we used a change in motor score of Functional Independent Measure (FIM-M) of convalescent rehabilitation to investigate whether daily energy intake could influence the rehabilitation outcomes. Of the 217 patients hospitalized in our convalescent rehabilitation ward (CRW) between September 2016 and February 2017, 162 met the eligibility criteria for this study.

Results: For a 25 kcal/ ideal body weight (IBW)/day cutoff point, 76 patients consumed more than 25 kcal/IBW/day of energy (H-E group), and 86 patients consumed up to 25 kcal/IBW/day of energy (L-E group). Patients in the L-E group had poorer nutritional status than those in the H-E group at CRW admission. Moreover, patients in the L-E group lost some body weight (BW) during hospitalization, whereas patients in the H-E group gained some BW. Furthermore, the FIM-M efficiency in the L-E group was significantly lower than that in the H-E group.

Conclusions: We concluded that appropriate nutritional management given to rehabilitation patients for adequate energy intake to maintain or gain their BW could maximize the outcome of convalescent rehabilitation.
