Abstract

Objectives

Prostate-specific membrane antigen (PSMA) positron emission tomography/computed tomography (PET/CT) has emerged as a promising imaging tool in prostate cancer diagnosis. PSMA PET/CT radiotracers are produced in-house (gallium-68, eg, F-DCFPyL). Nevertheless, the cost per procedure is not well established given that current estimates have several limitations. This study aimed to establish the cost of PSMA PET/CT in Australia.

Methods

Hospitals and diagnostic facilities currently conducting PSMA PET/CT in Australia in metropolitan and regional areas completed a survey of PSMA PET/CT throughput, radiotracers involved, and the cost of assets, departmental staffing, consumables, and occupancy. Total costs were estimated using a top-down microcosting approach, involving identifying all relevant cost components and valuing each component for the average patient, and a gross costing approach, involving apportioning cost components at an aggregated level.

Results

Data were collected from 8 facilities. The most common radiotracer used was Ga-PSMA-11 (4 facilities, 50%). The average cost of PSMA PET/CT was A$1554.77 and A$1306.00 based on the microcosting and gross costing approaches, respectively.

Conclusions

This study provides a detailed and accurate estimation of the cost of PSMA PET/CT in Australia. These costs can be used as a benchmark to identify potential efficiencies and help policy makers set the appropriate reimbursement rate for this procedure. The use of data from facilities using different radiotracers in metropolitan and regional areas and with different throughput increases the generalizability of the results, especially in countries with similar health systems.
