To the minor injury unit (MIU) at Swansea's Singleton Hospital
The Singleton Assessment Unit (SAU) will relocate to another part of the hospital, Ward 20, as the heavy duty refurbishment work can not be carried out alongside patients.
The relocation of the SAU will, however, affect the hospital's minor injury unit, which is next door to the SAU.
The minor injury unit will close from Monday, November 12 until early spring 2019.
The MIU's opening hours are 8am to 8pm on weekdays, 8am to 1pm on weekends, and it's staffed by GPs. However, for some time staffing the unit reliably has been a struggle.
The MIU has been forced to close at very short notice because it was open every Sunday for 17 weeks.
Patients can not be notified about short notice closures, so some arrive and find it closed.
Until now, but during the refurbishment they will be in another part of the hospital.
ABMU Health Board states that there is not enough room in Ward 20 to relocate MIU as well, so it is not an option to move both services together.
Doctors are therefore concerned about the safety risks to MIU patients who could not find them.
GP Dr Stephen Greenfield said: "We strongly feel the need to be close to the MIU while the SAU refurbishment is underway, and re-open it in the early spring, once the work is complete.
"If you have any problems, you are a very real risk that if you have arrived, you would not be able to help them."
"If this was to be done, the SAU staff would be able to arrange for an emergency transfer to Morriston Hospital. SAU staff have moved elsewhere.
"For this reason it is safer to temporarily close to MIU completely.
"We can then ensure we can alert people, including a communication campaign, changing our signs, and amending website information and so on.
"Once the work is complete, the MIU will re-open."
The Singleton Assessment Unit (SAU) refurbishment
The Singleton Assessment Unit (SAU) is a "front door service" dealing with patients directly from GPs and other community health professionals.
It also receives patients evaluated as an admission.
The SAU sees about 8,500 medical admissions a year and will be undergo major improvements over the next four months.
The £ 300,000 work will include building new bathrooms, redesigning the layout and providing additional space for non-clinical support staff, freeing up more room for patients.
Demand on Singleton's SAU is increasing, with 16% more patients arriving last winter compared with 2016-17.
Which service to use while the Singleton MIU is closed
While the Singleton is closed, patients are being advised of alternative services including the Minor Injury Unit at Neath Port Talbot Hospital, and the Emergency Department at Morriston Hospital, Swansea.
111 service for advice at any time.
Other recent developments at the hospital include a £ 340,000 investment in a front-door comprehensive assessment service for older people, and £ 230,000 in an early respiratory condition.
Following the upgrade of the MIU, the health board and clinicians at the Singleton Hospital will begin an engagement exercise to talk about the urgent care front door services at the hospital.
