The health watchdog's calling for reform of the current models of care for older people.
Hiqa says the Covid-19 pandemic has highlighted the need for immediate changes in nursing homes.
The Oireachtas Covid-19 committee will meet this morning to discuss Hiqa's recent report on the impact the pandemic has had on nursing homes.
Nursing homes account for more than half of the country's deaths from the virus.
The watchdog will also speak about the impact the pandemic has had on current residents.
On recent inspections, some older people spoke of their fear of contracting the virus.
Others felt a deep sense of isolation and loneliness as a result of the visiting restrictions.
Infectious diseases consultant, Eoghan de Barra, says more visiting restrictions are likely in the coming weeks.
Hiqa's recent report on the impact of the pandemic in nursing homes made 86 recommendations.
It wlll say today that a large number of them need to be implemented immediately.
