ESPEN guideline on nutritional support for polymorbid medical inpatients

Open access

Abstract

BACKGROUND: Disease-related malnutrition in polymorbid medical inpatients is a highly prevalent syndrome associated with significantly increased morbidity, disability, short- and long-term mortality, impaired recovery from illness, and cost of care. AIM: As there are uncertainties in applying disease-specific guidelines to patients with multiple conditions, our aim was to provide evidence-based recommendations on nutritional support for the polymorbid patient population hospitalized in medical wards. METHODS: This update adheres to the standard operating procedures for ESPEN guidelines. We did a systematic literature search for 15 clinical questions in three different databases (Medline, Embase and the Cochrane Library), as well as in secondary sources (e.g. published guidelines), until July 12th. Retrieved abstracts were screened to identify relevant studies that were used to develop recommendations (incl. SIGN grading), which was followed by submission to Delphi voting. RESULTS: From a total of 3527 retrieved abstracts, 60 new relevant studies were analyzed and used to generate a guideline draft that proposed 32 recommendations (7x A, 11x B, 10x O and 4x GPP), which encompass different aspects of nutritional support including indication, route of feeding, energy and protein requirements, micronutrient requirements, disease-specific nutrients, timing, monitoring and procedure of intervention. The results of the first online voting showed a strong consensus (agreement of >90%) on 100% of the recommendations. Therefore, no final consensus conference was needed. CONCLUSIONS: Recent high-quality trials have provided increasing evidence that nutritional support can reduce morbidity and other complications associated with malnutrition in polymorbid patients. The timely screening of patients for risk of malnutrition at hospital admission followed by individualized nutritional support interventions for at-risk patients should be part of routine clinical care and multimodal treatment in hospitals worldwide. Use of this updated guideline offers an evidence-based nutritional approach to the polymorbid medical inpatients and may improve their outcomes.

TL;DR

This ESPEN guideline update provides 32 evidence-based recommendations on nutritional support for polymorbid medical inpatients, covering screening, assessment, energy/protein requirements, intervention, monitoring, and post-discharge continuation. It concludes that timely screening and individualized nutritional support can reduce morbidity and complications in this population.

Key findings

  • From 3527 screened abstracts, 60 new relevant studies were analyzed and a total of 100 studies were included; the guideline proposes 32 recommendations (7 A, 11 B, 10 O, 4 GPP), with >90% agreement on 100% of recommendations in the first online Delphi vote.
  • In a meta-analysis restricted to polymorbid patients using the guideline’s definition, nutritional support significantly reduced mortality (OR 0.68; 95% CI 0.51–0.91) and hospital readmissions (OR 0.64; 95% CI 0.45–0.90).
  • The EFFORT trial reported lower adverse clinical outcomes (adjusted OR 0.79, 95% CI 0.64–0.97) and lower 30-day mortality (adjusted OR 0.65, 95% CI 0.47–0.91) with individualized nutritional support targeting 1.2–1.5 g protein/kg/day, with per-patient cost savings of 199 € within 30 days.
  • Continued post-discharge nutritional support lowered mortality in a meta-analysis of 2438 patients (OR 0.63, 95% CI 0.48–0.84); in NOURISH, 90-day mortality was 4.8% vs 9.7% (RR 0.49, 95% CI 0.27–0.90, p=0.018).

Methods

  • Update of the 2018 ESPEN guideline following ESPEN standard operating procedures, conducted by a multidisciplinary team of 14 European specialists; it retained 12 PICO questions and addressed 3 non-PICO topics, with a new question on biomarkers predicting treatment response.
  • Systematic literature search for 15 clinical questions in Medline, Embase, and the Cochrane Library, plus secondary sources, with the primary-source update performed on 12 July 2022 since April 2016; abstracts were screened, full texts reviewed, and discrepancies resolved by consensus or a third reviewer.
  • Evidence was graded using SIGN, recommendations were drafted and submitted to online Delphi voting in April 2023; because of strong consensus on the first vote, no final consensus conference was held.

Limitations

  • The paper states that the rigorous methodological approach led to a lower number of included trials, that many published studies did not report multiple comorbidities or use typical key terms, and that there are no MeSH terms dedicated to multiple chronic conditions; authors were contacted for 16 papers, and for 11 unreachable papers the working group made consensus decisions (7 included, 4 excluded).
  • The paper states that some included studies were conducted in older populations, and that evidence for certain recommendations (e.g., recommendations 11, 22, and 23) is limited to the subgroup of polymorbid older patients; for some questions no studies were identified (e.g., comparing energy prediction equations with weight-based formulae, and multivitamin/multi-trace-element supplementation vs no supplements in exclusively orally fed polymorbid inpatients).
  • Evident from the text: many recommendations are graded O or GPP (10 O, 4 GPP), and several cited studies are small, non-randomized, underpowered for clinical outcomes, or at high risk of bias; the authors repeatedly call for further large-scale and head-to-head trials.

Each contradiction between two passages listed here was confirmed by an independent check.

  • Same trial has conflicting findings for energy intake

    Major

    The discussion of the protein-fortified menu trial says the intervention significantly improved energy intake, but a later discussion of the same trial [148] says there was no significant difference in energy intake between groups.

  • Conflicting three-month muscle-mass changes in the same trial

    Minor

    Two accounts of the Hegerová trial give the intervention group's change in lean body mass from admission to three months after discharge as +1.3 kg and −0.4 kg, respectively.

  • Cited publication predates the stated study period

    Minor

    The cost-effectiveness discussion describes a retrospective study using data through 2010, but its cited reference [44] is dated 2003.

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.

A language model drew the claims from the paper on 2026-10-23, under version 3 of the claim definition (model deepseek-v4.1-flash, prompt extract-v3).

A second model labelled each claim on 2026-10-23 (model jev-1.13-20260917, definition revision gold-guideline-v0.2).

Cited sources are checked with a language model’s help (gpt-6-sol).

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.
