  1. a Patient’s indirect cost was calculated by multiplying the average length of stay by 2018 GDP per capita and dividing by 365
  2. b Hospital’s standard input (net cost) was approved by 60% of hospital charges [23]
  3. c The specific input of ERAS was converted into the purchasing power parity of 100 yuan = 40.47 Swiss francs [24]
  4. d The absolute turnover of beds was assumed in this study because of the shortage of beds in tertiary hospitals (the average utilisation rate of beds in tertiary hospitals reached 97.5% in 2018 [18])
  5. Assuming that there are 30 days per month and the department has 20 beds [18]. The formula for calculating hospital benefit was as follows: hospital benefit = hospital charges per capita × number of patients admitted within one month = average hospitalisation cost × (20 × 30 ÷ average hospital stays).
