The objective of this study was to estimate the direct costs of hospitalized IPD cases. A prospective study was made in children aged <5 years diagnosed with IPD in two high-tech hospitals in Catalonia (Spain) between 2007-2009 (PCV7 period) and 2012-2015 (PCV13 period). Costs were calculated according to 2014 Catalan Health Service rates using diagnostic-related groups. In total, 319 and 154 cases were collected, respectively. Pneumonia had the highest cost (65.7% and 62.0%, respectively), followed by meningitis (25.8% and 26.1%, respectively). During 2007-2015, the costs associated with PCV7 serotypes (Pearson coeffcient (Pc) = 􀀀0.79; p = 0.036) and additional PCV13 serotypes (Pc = 􀀀0.75; p = 0.05) decreased, but those of other serotypes did not (Pc = 0.23 p = 0.62). The total mean cost of IPD increased in the PCV13 period by 31.4% (¿3016.1 vs. ¿3963.9), mainly due to ICU stay (77.4%; ¿1051.4 vs. ¿1865.6). During the PCV13 period, direct IPD costs decreased due to a reduction in the number of cases, but cases were more severe and had a higher mean cost. During 2015, IPD costs increased due to an increase in the costs associated with non-PCV13 serotypes and serotype 3 and this requires further investigation.15 p.application/pdfengcc-by (c) Hernández, Sergi et al., 2020http://creativecommons.org/licenses/by/3.0/esVacuna antipneumocòccicaInfantsPneumococcal vaccineChildrenImpact of the 13-valent conjugated pneumococcal vaccine on the direct costs of invasive pneumococcal disease requiring hospital admission in children aged < 5 years.
