#' Information of SAPS II score and outcome of 1,000 ICU patients.
#'
#' A dataset containing clinical information of 1,000 patients admitted to Italian Intesive Care Units
#' joining the GiViTI network (\emph{Gruppo Italiano per la valutazione degli interventi in Terapia Intensiva},
#' Italian Group for the Evaluation of the Interventions in Intensive Care Units). The data has
#' been collected within the ProSAFE project, an Italian observational study based on a continuous
#' data collection of clinical data in more than 200 Italian ICUs. The purpose of the project is a
#' continuous surveillance of the quality of care provided in the participating centres.
#' The actual values of the variables have been modified to protect subject confidentiality.
#'
#' The data contain the information to apply the SAPSII model, a prognostic model developed to
#' predict hospital mortality (Le Gall et al., 1993).
#' Both the computed SAPSII score and the associated probability of death are variables of the dataset.
#' The score is an integer number ranging from 0 to 163 describing the severity of the patient (the higher
#' the score, the more severe the patient). The probability is computed from the score through the formula
#' reported in the original paper. The dataset contains also the hospital survival of the patients.
#'
#' @format A data frame with 1000 rows and 33 variables. The dataset contains, for each predictor of the SAPSII score,
#' both the clinical information and the weight of that variable in the score (the variable with the suffix '_NUM').
