#' danish.ed.primary
#'
#' Data from a Danish study on triage in an emergency department (ED)
#'
#' Data from a prospective cohort study of triage scoring for an emergency
#' department (ED).  The study examined whether the use of patient level
#' measurements would improve an existing triage score. These data are the
#' training data (called primary data in the original manuscript) used for model
#' building. Some variable names have been changed for readability, but the data
#' on 21 variables for the 6,249 participants are otherwise unchanged.

#' @docType data
#' @format A tibble with 6249 rows and 21 variables:
#' \describe{
#'    \item{\code{mort30}}{numeric, 1 if patient died within 30 days of admission, 0
#'    otherwise}
#'    \item{\code{triage}}{factor, triage score given at arrival to ED.
#'    Values \code{green}, \code{yellow}, \code{orange}, \code{red}, from lowest
#'    to highest priority
#'    for treatment.  The value \code{blue} normally denotes severity not
#'    warranting admission to the ED, but no participants coded blue
#'    are in these data.}
#'    \item{\code{age}}{numeric, age in years, rounded to lower integer}
#'    \item{\code{sex}}{factor, values \code{female}, \code{male}}
#'    \item{\code{albumin}}{numeric, serum albumin, in g/L}
#'    \item{\code{creatinine}}{numeric, serum creatinine, in umol/L}
#'    \item{\code{hemaglobin}}{numeric, serum hemaglobin, in mmol/L }
#'    \item{\code{potassium}}{numeric, serum potassium, in mmol/L}
#'    \item{\code{leuk.count}}{blood leukocyte count, in 10E9/L}
#'    \item{\code{sodium}}{numeric, serum sodium, in mmol/L}
#'    \item{\code{c.react.protein}}{numeric, serum C-reactive protein}
#'    \item{\code{oxygen.sat}}{numeric, peripheral arterial oxygen saturation, as a percent}
#'    \item{\code{resp.rate}}{numeric, respiratory rate per minute}
#'    \item{\code{heart.rate}}{numeric, heart rate, beats/min}
#'    \item{\code{systolic.bp}}{numeric, systolic blood pressure, in mmHg}
#'    \item{\code{glasgow.coma.scale}}{numeric, extent
#'    of impaired consciousness in patients with acute medical condition or
#'    trauma, scored between 3 and 15, 3 being the worst and 15 the best. Score
#'    is based on 3 subscales, best eye, verbal and motor responses.}
#'    \item{\code{readmit.hosp}}{factor, readmitted to hospital within 30 days,
#'    values \code{yes}, \code{no}}
#'    \item{\code{days.in.hosp}}{numeric, number of days admitted to hospital}
#'    \item{\code{icu.time}}{numeric, number of days in the intensive care unit.
#'    value 99999 indicates patient not admitted to ICU}
