Abstract

Background & aims: COVID-19 patients present a high hospitalization rate with a high mortality risk for those requiring intensive care. When these patients have other comorbid conditions and older age, the risk for severe disease and poor outcomes after ICU admission are increased. The present work aims to describe the preliminary results of the ongoing NUTRICOVID study about the nutritional and functional status and the quality of life of adult COVID-19 survivors after ICU discharge, emphasizing the in-hospital and discharge situation of this population. Methods: A multicenter, ambispective, observational cohort study was conducted in 16 public hospitals of the Community of Madrid with COVID-19 survivors who were admitted to the ICU during the first outbreak. Preliminary results of this study include data retrospectively collected. Malnutrition and sar-copenia were screened at discharge using MUST and SARC-F; the use of healthcare resources was measured as the length of hospital stay and requirement of respiratory support and tracheostomy during hospitalization; other study variables were the need for medical nutrition therapy (MNT); and patients' functional status (Barthel index) and health-related quality of life (EQ-5D-5L). Results: A total of 176 patients were included in this preliminary analysis. Most patients were male and older than 60 years, who suffered an average (SD) weight loss of 16.6% (8.3%) during the hospital stay, with a median length of stay of 53 (27-89.5) days and a median ICU stay of 24.5 (11-43.5) days. At discharge, 83.5% and 86.9% of the patients were at risk of malnutrition and sarcopenia, respectively, but only 38% were prescribed MNT. In addition, more than 70% of patients had significant impairment of their mobility and to conduct their usual activities at hospital discharge. Conclusions: This preliminary analysis evidences the high nutritional and functional impairment of COVID-19 survivors at hospital discharge and highlights the need for guidelines and systematic protocols, together with appropriate rehabilitation programs, to optimize the nutritional management of these patients after discharge.

Quality index

Bibliometric impact. Analysis of the contribution and dissemination channel

The work has been published in the journal CLINICAL NUTRITION due to its progression and the good impact it has achieved in recent years, according to the agency WoS (JCR), it has become a reference in its field. In the year of publication of the work, 2022, it was in position 14/88, thus managing to position itself as a Q1 (Primer Cuartil), in the category Nutrition & Dietetics.

From a relative perspective, and based on the normalized impact indicator calculated from World Citations provided by WoS (ESI, Clarivate), it yields a value for the citation normalization relative to the expected citation rate of: 5.1. This indicates that, compared to works in the same discipline and in the same year of publication, it ranks as a work cited above average. (source consulted: ESI Nov 14, 2024)

This information is reinforced by other indicators of the same type, which, although dynamic over time and dependent on the set of average global citations at the time of their calculation, consistently position the work at some point among the top 50% most cited in its field:

  • Weighted Average of Normalized Impact by the Scopus agency: 6 (source consulted: FECYT Feb 2024)
  • Field Citation Ratio (FCR) from Dimensions: 8.25 (source consulted: Dimensions Jun 2025)

Specifically, and according to different indexing agencies, this work has accumulated citations as of 2025-06-05, the following number of citations:

  • WoS: 22
  • Scopus: 24
  • OpenCitations: 30

Impact and social visibility

From the perspective of influence or social adoption, and based on metrics associated with mentions and interactions provided by agencies specializing in calculating the so-called "Alternative or Social Metrics," we can highlight as of 2025-06-05:

  • The use, from an academic perspective evidenced by the Altmetric agency indicator referring to aggregations made by the personal bibliographic manager Mendeley, gives us a total of: 140.
  • The use of this contribution in bookmarks, code forks, additions to favorite lists for recurrent reading, as well as general views, indicates that someone is using the publication as a basis for their current work. This may be a notable indicator of future more formal and academic citations. This claim is supported by the result of the "Capture" indicator, which yields a total of: 139 (PlumX).

With a more dissemination-oriented intent and targeting more general audiences, we can observe other more global scores such as:

  • The Total Score from Altmetric: 8.4.
  • The number of mentions on the social network X (formerly Twitter): 15 (Altmetric).

It is essential to present evidence supporting full alignment with institutional principles and guidelines on Open Science and the Conservation and Dissemination of Intellectual Heritage. A clear example of this is:

  • The work has been submitted to a journal whose editorial policy allows open Open Access publication.
