Multi-parametric magnetic resonance imaging of the prostate in Victoria, Australia; unintended consequences of changing Medicare Benefits Schedule access.

Abstract

ObjectiveTo assess whether prostate biopsy rates have altered with the July 2018 change in Australian Medicare Benefits Schedule (MBS) rebates supporting multiparametric magnetic resonance imaging (mpMRI) for diagnosing prostate cancer.MethodsBiopsy data (both trans-rectal and trans-perineal) were obtained from the Victorian Agency for Health Information from July 2016 to June 2022. The data were stratified by financial year, age group and hospital type (public vs private). Comparison was made between rates pre and post the mpMRI MBS code change.ResultsThere was an 11.9% increase in the number of biopsies performed per year compared to the pre-MBS change period. There is a significant decreasing trend (P<0.001-4) in number of biopsies in the 40-49, 50-59 and 60-69-year-old age groups with a significant increasing trend (P<0.001) in the 70-79 and 80-89-year-old age groups. There was a 32.9% reduction in the mean number of biopsies performed per year in public hospitals, compared with an 18.3% increase in private.ConclusionContrary to expectations, and proposed funding, there has been an increase in the number of prostate biopsies since MRI became more easily available. This change will put increased pressure on the health budget and the large increase in biopsies in elderly patients was not anticipated when the changes were proposed. A review of the criteria is suggested.
