In HealthEconomicsHackathon/inflatably: Inflating Costs to Present Value (PV) Using Different Source Rates

#' PSSRU annual inflation hospital and community health services (HCHS)
#'
#' Until 2016/2017, a hospital & community health services (HCHS) index was calculated
#' by the Department of Health (now DHSC). The hospital and community health services (HCHS)
#' pay and price inflation was a weighted average of two separate inflation indices: the pay
#' cost index was calculated using the annual increase in NHS salaries and the Health Service
#' Cost Index (HSCI) measured the price change for each of 40 sub-indices of goods and
#' services purchased by the HCHS. These were weighted according to the proportion of
#' expenditure on pay and prices to give the HCHS pay and prices index.
#' In 2016, this index was discontinued, and in 2018, in collaboration with the DHSC,
#' PSSRU have developed a new inflation index.
