The Public Accounts Committee will question the Health Service Executive today over the delay in delivering primary care centres.
Just over a third of the planned centres have been built.
A report by the Comptroller and Auditor General earlier this year said the national network of primary care centres may not be rolled out for another 20 years.
The report found that the Department of Health had a target for the centres to be located in 350 locations.
However, it revealed that only 57 centres were introduced since 2013, bringing the total number to 127 by March this year.
Primary care centres are designed to be a one-stop shop for health services.
The C&AG report recommended that the HSE undertake a cost-effectiveness review of the different delivery methods used to develop primary care centres.
It also recommends that the HSE set a goal for when the full network is intended to be in place and determine how future delivery is to be prioritised.
In an opening statement to the PAC today, the HSE says it would implement the recommendations outlined in the C&AG's report.
The HSE said the 127 primary care centres are operational and a further 77 are in the process of being developed.
It said it will complete a review of primary care centres next year to help understand better how they are being used.
The HSE also said it will consider the utilisation of centres and how this would increase as services in the community are expanded.
It said that this would result in an extra 1,000 frontline staff being employed in community services.
