A total of 14,279 patients were hospitalized during the study period with an average of 1,78 hospitalizations episodes per patient in the 8-year interval(0.22 hospitalizations/patient/year). 68.0% of the hospitalizations occurred in male patients and the median length of stay was 18.0 days. Mean hospitalization charges were 3,509.7¤ per hospitalization, summed to a total charge of 89.1M¤. Throughout the study period there was a significant linear decrease in the number of hospitalizations (r = 0.940; B= -47.488; p = 0.001). The last year of the study(2015) had the lowest number of hospitalizations with a total of 2,958 (vs. 3,314 in 2008). When adjusted for the yearly population, there was also a decrease of the number of hospitalizations per 100,000 inhabitants from 31.39 to 28.56 hospitalizations per 100,000 inhabitants between 2008 and 2015, respectively.</jats:p></jats:sec><jats:sec id="S0924933821004259_sec1645" sec-type="conclusions"><jats:title>Conclusions</jats:title><jats:p>We found differences in hospitalization characteristics by gender, age and primary diagnosis.</jats:p></jats:sec><jats:sec id="S0924933821004259_sec1646"><jats:title>Disclosure</jats:title><jats:p>No significant relationships.</jats:p></jats:sec>
