Incremental cost is cost for the new method

minus

cost for the conventional method

Cost-analysis

Cost-analysis

To get the incremental cost for:

the new method -panoramic + CBCT

a comparison of costs is done with:

the conventional method -panoramic + intraoral radiography

Cost-analysis

Direct cost

•Capital cost - calculated for each radiographic machine:

•Equipment: Purchase cost divided by years of expected lifetime.

•Maintenance: annual cost of service and call out cost.

•Accommodation: cost per m2 multiplied with amount of m2 in clinic and office space.

•Consumables: amount and cost of disposable items used per examination

•Labour cost - total gross employment-cost per year divided with total amount of clinic hours (minus benefit-hours not paid for) to get labour-cost per hour.

•Radiologist: labour-cost per hour multiplied with time for assessment o radiography.•Radiographer: labour-cost per hour multiplied with time for taking radiographs.

Indirect costCost for the patient:

Valuation of time spent is done using information about average and minimum wage-cost in each country according to Eurostat Yearbook 2008.

Cost for time spent on: •Travelling - time spent going to and from the clinic.•Waiting – average time is estimated to 10-15min.•Examination – the total clinic time recorded in a form is divided by two in Cluj and Leuven and by three in Malmö and Vilnius.

“Out of pocket money”:•Cost for transport: cost per km, bus and train-tickets, parking•Fee: according to the tariff in the different countries.
