Abstract

Background: While sepsis may have especially marked impacts in young adults, there is limited population-based information on its epidemiology and trends. Methods: Population-based longitudinal study on sepsis in adults aged 20-44 years using the 2006-2015 Spanish national hospital discharge database. Cases are identified by an ICD-9-CM coding strategy. Primary endpoints are incidence and in-hospital mortality. Trends are assessed for annual percentage change (AAPC) in rates using Joinpoint regression models. Results: 28,351 cases are identified, representing 3.06 parts per thousand of all-cause hospitalisations and a crude incidence of 16.4 cases/100,000 population aged 20-44. The mean age is 36 years, 58% of cases are men, and around 60% have associated comorbidities. Seen in one third of cases, the source of infection is respiratory. Single organ dysfunction is recorded in 45% of cases. In-hospital mortality is 24% and associated with age, comorbidity and extent of organ dysfunction. Incidence rates increase over time in women (AAPC: 3.8% (95% CI: 2.1, 5.5)), whereas case-fatality decline with an overall AAPC of -5.9% (95% CI -6.6, -5.2). Our results indicate that sepsis is common in young adults and associated with high in-hospital mortality, though it shows a decreasing trend. The substantial increase in incidence rates in women needs further research.

Quality index

Bibliometric impact. Analysis of the contribution and dissemination channel

The work has been published in the journal Journal of Clinical Medicine 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, 2020, it was in position 39/169, thus managing to position itself as a Q1 (Primer Cuartil), in the category Medicine, General & Internal.

From a relative perspective, and based on the normalized impact indicator calculated from the Field Citation Ratio (FCR) of the Dimensions source, it yields a value of: 5.44, which 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: Dimensions Jul 2025)

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 2025-07-09:

  • 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: 51.
  • 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: 53 (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: 1.75.
  • The number of mentions on the social network X (formerly Twitter): 3 (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.
