MSPs will start hearing evidence later about safety and infection rates in Scotland’s NHS.
The inquiry was launched by Holyrood’s health and sport committee after a series of infection outbreaks at the Queen Elizabeth University Hospital in Glasgow.
Two people died after contracting an infection related to pigeon droppings.
The committee’s probe will have a wider focus than an investigation into the QEUH ordered by the health secretary.
The MSP’s inquiry was set up after problems with ventilation, water hygiene and building maintenance were identified at Scotland’s largest hospital.
They want to examine whether infection control is adequate and whether more can be done to improve patient safety.
The committee has already accepted written evidence and will hear from executives responsible for managing and monitoring safety in healthcare settings.
