The Irish Hospital Consultants Association says that the agreement between the government and private hospitals will have a negative impact on private patients.
Last week it was announced private hospitals would be used by the state to treat both Covid-19 and non Covid-19 patients.
However around 500 consultants at private hospitals say a large number of outpatient consultations will be impacted as a result, and will have a detrimental impact on the quality of care received by these patients.
The group says consultants should allow them to continue to treat private patients as well as obligating their new HSE contract.
