Treatment costs
Costs were collected from societal perspective, so the costs included
direct medical (DMC) and non-medical costs (DNMC) as well as indirect
costs (IC). DMC included patient’s hoteling in hospital, medications
used for hospital patients, laboratory and pathology tests, surgical
costs, and other health services for each patient in the inpatient and
day case tonsillectomy group. DNMC included the transportation costs for
patients and their companions, the money paid for accommodation and
meals by patients’ companions for both hospitalized and day-to-day
tonsillectomy in hospital. IC also included the patients’ average of
absence days from work, the companions’ average of absence days from
work to take care of their patients and the lost productivity.
Costs calculation was according to tariffs of 2018 in the international
dollar (purchasing power parity (PPP)). Furthermore, the exchange rate
of each PPP$ was equal to 12800 rials (IRR)(13).
