- COVID-19 Vaccine Effectiveness Against Hospitalization in Older Adults, VEBIS Hospital Network, Europe, September 2024-May 2025Publication . Rojas-Castro, Madelyn; Verdasca, Nuno; Monge, Susana; De Mot, Laurane; Trobajo-Sanmartín, Camino; Duffy, Róisín; Túri, Gergő; Kuliese, Monika; Duerrwald, Ralf; Borg, Maria-Louise; Popovici, Odette; Gomez, Verónica; Makarić, Zvjezdana Lovrić; Launay, Odile; Marques, Diogo F.P.; Pozo, Francisco; Witdouck, Arne; Martínez-Baz, Iván; Fitzgerald, Margaret; Oroszi, Beatrix; Jančorienė, Ligita; Buda, Silke; Dziugyte, Ausra; Lazăr, Mihaela; Machado, Ausenda; Tabain, Irena; Nguyen, Liem Binh Luong; Wagner, Eva Rivas; Dufrasne, François; Castilla, Jesús; Domegan, Lisa; Velkey, Viktória; Majauskaite, Fausta; Hackmann, Carolin; Nicolay, Nathalie; Bacci, Sabrina; Rose, Angela M.C.; European Hospital Vaccine Effectiveness GroupWe estimated COVID-19 vaccine effectiveness (VE) against PCR-confirmed SARS-CoV-2 hospitalization in patients ≥ 60 years with severe acute respiratory infection, using a multicenter, test-negative, case-control study across seven sites in six European countries between September 2024 and May 2025. We included 352 cases (115 vaccinated; 33%) and 9980 controls (5024 vaccinated; 50%). VE was 42% (95% CI: 15; 61) 14-59 days post-vaccination, 32% (95% CI: -1; 54) at 60-119 days, and 36% (95% CI: 2; 60) at 120-179 days, and no effect thereafter. Among adults aged 60-79 and ≥ 80 years, we observed moderate VE against COVID-19 hospitalization for up to 2 and 4 months, respectively.
- Surveillance of severe acute respiratory infections associated with SARS-CoV-2, influenza virus and RSV using ICD-10 codes: a case definition accuracy study across five European countries, 2021 to 2023Publication . Sanchez Ruiz, Miguel Angel; Marques, Diogo Fp.; Lomholt, Frederikke Kristensen; Vestergaard, Lasse Skafte; Monge, Susana; Lozano Álvarez, Marcos; Aspelund, Gudrun; Thordardottir, Marianna; Dziugyte, Ausra; Cauchi, John-Paul; Boere, Tjarda M.; Veldhuijzen, Irene K.; Seppälä, Elina; Bøås, Håkon; Paulsen, Trine Hessevik; Machado, Ausenda; Rodrigues, Ana Paula; Hooiveld, Mariette; Alves de Sousa, Luis; Torres, Ana; Carvalho, Carlos; Nunes, BaltazarBackgrounds: Surveillance of severe acute respiratory infections (SARI) using ICD-10 codes from electronic health records (EHR) lacks consensus on optimal case-defining codes.AIMWe determined codes that maximise sensitivity (Se) and positive predictive value (PPV) for SARI associated with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), influenza virus and respiratory syncytial virus (RSV) in Denmark, Iceland, Malta, Norway and Spain.METHODSWe included hospitalisations from week 21/2021 to 39/2023, with ICD-10 diagnostic codes for respiratory disease (three-character codes J00-J99) or COVID-19 (U07.1, U07.2, country-specific codes for Denmark). We assessed Se and PPV of individual codes against laboratory results. Based on Se and PPV rank-sum, we selected the top 10 codes and combined them into 10 sets per pathogen. We identified sets that maximised the clinical utility index (CUI = Se × PPV), categorised as excellent (≥ 0.81), good (0.64-0.80), satisfactory (0.49-0.63) and poor (< 0.49).RESULTSWe assessed 395,163 hospitalisations for SARI-SARS-CoV-2, 313,418 for SARI-influenza and 192,936 for SARI-RSV, all tested. For SARI-SARS-CoV-2, code U07.1 (B34.2A, B97.2A for Denmark) had excellent utility in Denmark, Malta, Norway, Spain (≥ 0.82), and good utility in Iceland (0.79). For SARI-influenza, J09, J10 and J11 performed excellently in Denmark, Norway, Spain (≥ 0.83), satisfactorily in Malta (0.52), and poorly in Iceland (0.43). For SARI-RSV, J12, J20 and J21 achieved highest CUI but had poor utility (0.17-0.34).CONCLUSIONSCOVID-19- and influenza-specific three-character ICD-10 codes accurately identified SARI associated with SARS-CoV-2 and influenza virus. For SARI-RSV, four-character codes should be explored. We recommend context-specific assessments in countries adopting EHR-based surveillance.
