The Irish Hospice Foundation says it fears it will not be able to provide home care services for children because of HSE cutbacks.
The IHF says the planned €666m in Health Service cutbacks throws the HSE's commitment to fund three of the country's eight Children's Outreach Nurses into doubt.
The IHF itself funds 85% of the children's programme, a level it says is "unsustainable".
CEO Sharon Foley says the HSE needs to clarify where it stands.
