ABSTRACT
Las infecciones por Streptococcus pneumoniae originan una importante morbilidad y mortalidad. Entre las personas más susceptibles a su desarrollo se encuentran las de mayor edad, los pacientes inmunodeprimidos y aquellos con comorbilidad, pudiendo presentar además una mayor gravedad y una evolución más desfavorable. Las pautas de vacunación frente al neumococo tienen como objetivo disminuir la incidencia de estas infecciones. Las recomendaciones para ello han ido cambiando a lo largo de los años. La reciente aprobación de la vacuna neumocócica conjugada 20-valente simplifica la pauta previa, al unificar las indicaciones de vacunación en población adulta a partir de los 60 años con y sin factores predisponentes, así como en menores de 60 años con condiciones de riesgo. Está autorizada para mayores de 18 años, por lo que en menores se mantiene la pauta previa: a) si no hay factores ni condiciones de riesgo, se indican tres dosis de vacuna neumocócica conjugada 13 o 15-valente a los 2, 4 y 11 meses; b) si existen factores o condiciones de riesgo, a partir de los 2 años de edad puede ser necesario asociar la vacuna neumocócica de polisacáridos de 23 serotipos.

Streptococcus pneumoniae infections cause significant morbidity and mortality. Among the people most susceptible to infections are the elderly, immunosuppressed patients, and those with comorbidities, presenting a greater severity and a more unfavorable condition. Vaccination guidelines against pneumococcus aim to reduce the incidence of these infections, whose recommendations have changed over the years. The recent approval of the 20-valent conjugate pneumococcal vaccine simplifies the previous regimen, by unifying the indications for vaccination in the adult population aged 60 years and older with and without predisposing factors, as well as in those aged under 60 years with conditions of risk. It is authorized for the individuals aged over 18 years, so the previous regimen has been maintained in minors: a) if there are no risk factors or conditions, three doses are indicated: 13- or 15-valent pneumococcal conjugate vaccine at 2, 4, and 11 months and b) if there are risk factors or conditions, it may be necessary to associate the 23 serotypes pnemococcal polysaccharide vaccine from 2 years of age.

BACKGROUND: Knowing the cost of hospitalizations for exacerbation in bronchiectasis patients is essential to perform cost-effectiveness studies of treatments that aim to reduce exacerbations in these patients. OBJECTIVES: To find out the mean cost of hospitalizations due to exacerbations in bronchiectasis patients, and to identify factors associated with higher costs. METHODS: Prospective, observational, multicenter study in adult bronchiectasis patients hospitalized due to exacerbation. All expenses from the patients' arrival at hospital to their discharge were calculated: diagnostic tests, treatments, transferals, home hospitalization, admission to convalescence centers, and hospitals' structural costs for each patient (each hospital's tariff for emergencies and 70% of the price of a bed for each day in a hospital ward). RESULTS: A total of 222 patients (52.7% men, mean age 71.8 years) admitted to 29 hospitals were included. Adding together all the expenses, the mean cost of the hospitalization was EUR 5,284.7, most of which correspond to the hospital ward (86.9%), and particularly to the hospitals' structural costs. The adjusted multivariate analysis showed that chronic bronchial infection by Pseudomonas aeruginosa, days spent in the hospital, and completing the treatment with home hospitalization were factors independently associated with a higher overall cost of the hospitalization. CONCLUSIONS: The mean cost of a hospitalization due to bronchiectasis exacerbation obtained from the individual data of each episode is higher than the cost per process calculated by the health authorities. The most determining factor of a higher cost is chronic bronchial infection due to P. aeruginosa, which leads to a longer hospital stay and the use of home hospitalization.
