Abstract

Outpatient parenteral antibiotic treatment (OPAT) has proven efficacious and safe for treating infective endocarditis (IE). However, the 2001 IDSA criteria for OPAT in IE are very restrictive. We aimed to compare the outcomes of OPAT with those of hospital-based antibiotic treatment (HBAT).Retrospective analysis of data from a multicenter prospective cohort study of 2,000 consecutive IE patients in 25 Spanish hospitals from 2008 to 2012.A total of 429 patients (21.5%) received OPAT, and only 21.7% fulfilled IDSA criteria. Males accounted for 70.5%, median age was 68 years (IQR 56-76), 57% had native-valve IE, 27% had prosthetic-valve IE, and 19% had pacemaker/defibrillator IE. The most frequent causal microorganisms were viridans group streptococci (18.6%), Staphylococcus aureus (15.6%), and coagulase-negative staphylococci (14.5%). The median length of antibiotic treatment was 42 days (IQR 32-54), and 44% of patients underwent cardiac surgery. One-year mortality was 8% (42% for HBAT; P<0.001), 1.4% of patients relapsed, and 10.9% were readmitted during the first three months after discharge (no significant differences compared with HBAT). Charlson score (OR 1.21, 95%CI 1.04-1.42; P=0.01) and cardiac surgery (OR 0.24, 95%CI 0.09-0.63; P=0.04) were associated with one-year mortality, whereas aortic valve involvement (OR 0.47, 95%CI 0.22-0.98; P=0.007) was the only predictor of readmission at one year. Failing to fulfill IDSA criteria was not a risk factor for mortality or readmission.OPAT provided excellent results despite the use of broader criteria than those recommended by IDSA; OPAT criteria should therefore be expanded.

Quality index

Bibliometric impact. Analysis of the contribution and dissemination channel

The work has been published in the journal Clinical Infectious Diseases 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, 2019, it was in position 3/92, thus managing to position itself as a Q1 (Primer Cuartil), in the category Infectious Diseases. Notably, the journal is positioned above the 90th percentile.

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: 3.21. 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: 1.31 (source consulted: FECYT Feb 2024)
  • Field Citation Ratio (FCR) from Dimensions: 20.18 (source consulted: Dimensions Jul 2025)

Specifically, and according to different indexing agencies, this work has accumulated citations as of 2025-07-07, the following number of citations:

  • WoS: 60
  • Scopus: 27
  • Europe PMC: 24

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 2025-07-07:

  • 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: 132.
  • 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: 136 (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: 34.45.
  • The number of mentions on the social network X (formerly Twitter): 55 (Altmetric).
