Deputy Toibin feels the issue stems from bed shortages, staffing gaps, and lack of consultant cover.
Aontu's leader is demanding the Health Minister take accountability over serious overcrowding in a Midlands hospital.
Meath West TD Peadar Toibin says a memo has been sent to staff in Midland Regional Hospital Tullamore on reaching a "black escalation" status.
The term is the most severe declared by a hospital in the HSE system, meaning it's clinically unsafe.
Deputy Toibin feels it's a mix of bed capacity, staffing and consultant cover issues contributing to the situation.
He says the retention of nurses and doctors is adding to the problem:
