  • Analysis of the Spanish National Hospital Discharge Database from 2004 to 2013.

  • Charlson Comorbidity Index, excluding dementia and diabetes.

  • p Value for comparison by year.

  • Poisson regression model to assess trends in incidence rates, analysis of variance and Pearson's χ2 for means and proportions, respectively.

  • N, number of discharges.
