  1. aThe daily expense was calculated for each patient as total psychiatric/non-psychiatric expenses of 3 years divided by the total psychiatric/non-psychiatric hospital days
  2. bThe denominator for the mean was patients with non-psychiatric admission in the 3-year observation period
  3. cThe proportion of the non-psychiatric expense in the total expense was calculated as total non-psychiatric expense/(total psychiatric expense + total non-psychiatric expense)*100%
