Hospital length of stay and nutritional status
Abstract
Purpose of review This review looks at the recent medical literature on the association between hospital length of stay and nutritional status. Recent findings Simple anthropometric parameters underestimate the nutritional risk in hospitalized patients. The Malnutrition Universal Screening Tool and Nutritional Risk Screening are simple screening tools that identify patients who require further monitoring. Recent weight loss appears to be the most important single indicator of nutritional status. Body composition measurements identify patients with muscle mass depletion and excess body fat, both of which are significantly associated with increased length of stay. The Subjective Global Assessment is useful at detecting patients with established malnutrition and the Mini Nutritional Assessment for the elderly is useful at detecting patients who need preventive nutritional measures. The Nutritional Risk Index, which incorporates albumin and weight loss, appears to capture both nutritional risk and poor clinical outcome. Summary Nutritional risk is associated with the length of stay in hospital. The choice of nutritional screening and assessment tools depends on the type of institution (university hospital versus community hospital), the patient populations (acute care versus intermediary care; general hospital versus elderly population) and the resources available.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
