In nhds: National Hospital Discharge Survey 2010 Data

#' @title National Hospital Discharge Survey 2010 data
#' @description The United States National Hospital Discharge Survey (NHDS) 2010
#'   data is public domain data from the US [Center for Disease
#'   Control](https://www.cdc.gov). This is de-identified patient data with
#'   summary information about each patient at the end of a hospital admission,
#'   including demographic information, admission diagnoses, comorbidities and
#'   procedure codes, death or disposition. There are no identifiers in the
#'   data, so a simple count was included.
