Dear Brainstrust
Some time ago, I came across a novel configuration of a single room that provides for both protective (positive pressure barrier) and isolation (negative pressure) requirements. Extensive testing was described at the Hospital Infection Society Conference, Amsterdam 2006. It was specified under Building Note 4 by HEFMA but the link no longer works and I’ve been unsuccessful with chasing down the design. Concept involves an isolation room with a positive pressure anteroom and exhaust from the ensuite room which is entered from the main room. The design is relatively fail-safe and does not need to be manually configured.
I wondered whether anyone has come across this? Has anyone built functioning dual purpose isolation/barrier rooms? We are building a new paed ICU and we need both types of room !
thanks
John

Hi John, someone on this list posted a link to a portable isolation / negative pressure / antechamber system that looked quite interesting, where you could set up such a system over a single bed without having to have a specific room purpose built.
I can’t remember the product / company however, and am not sure on the clinical efficacy/evidence around this type of equipment / system but may be worth a look (if someone else can recall the post with the link to the company – I deleted it as not much call in my area for this!!!)
Good luck!

Dear John,
We’ve got 2 dual-purpose isolation rooms currently in service that were probably based on older guidelines (before my time here).
These rooms have the ability to switch from positive to negative pressure by the flick of a key-switch (the ante-room is always positive pressured with the exhaust located in the ensuite).
Current guidelines do not support these designs owing to the huge risk they pose if activated incorrectly by staff e.g. sputum positive TB cases having positive pressure instead of negative pressure by inattentive staff, etc.
It would be preferable, from a risk perspective, that your Type 5 negative pressured rooms remain as dedicated negative pressured ones… these settings are thus pre-configured and your Engineering departments then conduct regular servicing and monitors the air pressure exchanges.
We are currently undergoing a major hospital redevelopment and have factored in dedicated Type 5 negative pressured rooms in our planning for various wards.
Airflow for these rooms come via positive pressure from the anteroom and from the doorway leading to the ward corridor (if the door is temporarily opened)… the air then flows to the negative pressured exhausts in the ensuite and the main room.
The air is exhausted out of the building immediately and does not get re-circulated (some older designs filter the exhausted air from these rooms or not at all, and re-circulate it… this is not ideal).
I’m very keen to have a look at the functional design of this novel concept isolation room should you manage to find the link, John.

Hi John
When we renovated our ICU in 2004, we created 4 isolation rooms at
positive pressure relative to the anteroom and sluice room.The anteroom and sluice room is at negative pressure relative to the
isolation room and corridor. These are used primarily for our Burns
patients and immunocompromised patients with ARO’s.Although in principle you should be able to utilise this for
immunocompromised patients with airborne infections as the ante room is
negative to corridor we opted not to take this risk. I cant recall us
ever having a Burns or immunocompromised patient with airborne
infections and if we did we would place them in a negative pressure room
with ante room negative to room and corridor.Our Burns unit was built in 2005 with positive pressure rooms, ante
rooms negative to isolation room but negative to corridor. We have not
had any ARO outbreaks in this unitRegards

Dear all,
thanks everybody for your replies very useful!I was particularly after the design that does not require switching of ventilation
Thanks to Marija, I’ve located the design which is described in the UK document, The link has been updated on the built environment web page. The design is called a positive pressure ventilated lobby room. Would be very interested to hear from anyone with experience of this design. Donna, is this the design you have ?

Hi John
It was something we came up with and designed with our engineer based on
infection prevention principles as there was not much out there in
recommendations when the design was started around 2002. So it has not
been validated except that we have not had any ARO outbreaks in our unit
despite having to care for long term patients have very resistant ARO’s.Regards

HEFMA but the link no longer works and I’ve been unsuccessful with
chasing down the design. Concept involves an isolation room with a
positive pressure anteroom and exhaust from the ensuite room which is
entered from the main room. The design is relatively fail-safe and does
not need to be manually configured.I wondered whether anyone has come across this? Has anyone built
functioning dual purpose isolation/barrier rooms? We are building a new
paed ICU and we need both types of room !thanks

Hi John, just a couple of things to point out re the ‘Isolation Guidelines for Infectious Patients in Acute Settings’ (Department of Health UK) which I got to via the link on HICSIG:
The guidelines are only for isolation room design for infectious patients and the exclusions are (p8): ‘This manual does not describe the specialist facilities required in high security infectious disease units, isolation wards for cohorting groups of infectious patients,
protective isolation for severely immuno-compromised patients, critical care areas and special care baby units’. The document also states that ‘The provision of isolation rooms that are switchable from positive to negative air pressure is not recommended because of the risk to people inside and outside the room in the event of the setting being incorrect’ which is what the various guidelines in Australia also stress.
The guide outlines two options for isolation rooms – one is the ‘classic’ negative pressure ventilated room (negative pressure to the corridor) while the other is the positive pressure ventilated lobby (PPVL) room which has a positive pressure anteroom or lobby, a neutral or atmospheric pressure in the isolation room along with negative pressure in the en-suite. Both of these types are outlined as suitable for preventing airborne transmitted infections.
So I think caution needs to be used before using or quoting these guidelines in the design of rooms to provide both protective (positive pressure barrier) and isolation (negative pressure).Cheers
PS – Kevin Moon, an engineer from Victoria has done a lot of work re this issue and was one of the authors of the original Victorian Isolation Room Guidelines back in about 1998 I think. I do not know his current contact details but I could find them and send them to you off-line if you wish to chat to him.

A fair and healthy TasmaniaDear all,
thanks everybody for your replies – very useful!I was particularly after the design that does not require switching of ventilation
Thanks to Marija, I’ve located the design which is described in the UK document, The link has been updated on the built environment web page. The design is called a positive pressure ventilated lobby room. Would be very interested to hear from anyone with experience of this design. Donna, is this the design you have ? Rosie, your design is different – is it specified/validated anywhere?

Dear John,
We’ve got 2 dual-purpose isolation rooms currently in service that were probably based on older guidelines (before my time here).
These rooms have the ability to switch from positive to negative pressure by the flick of a key-switch (the ante-room is always positive pressured with the exhaust located in the ensuite).
Current guidelines do not support these designs owing to the huge risk they pose if activated incorrectly by staff e.g. sputum positive TB cases having positive pressure instead of negative pressure by inattentive staff, etc.
It would be preferable, from a risk perspective, that your Type 5 negative pressured rooms remain as dedicated negative pressured ones… these settings are thus pre-configured and your Engineering departments then conduct regular servicing and monitors the air pressure exchanges.
We are currently undergoing a major hospital redevelopment and have factored in dedicated Type 5 negative pressured rooms in our planning for various wards.
Airflow for these rooms come via positive pressure from the anteroom and from the doorway leading to the ward corridor (if the door is temporarily opened)… the air then flows to the negative pressured exhausts in the ensuite and the main room.
The air is exhausted out of the building immediately and does not get re-circulated (some older designs filter the exhausted air from these rooms or not at all, and re-circulate it… this is not ideal).
I’m very keen to have a look at the functional design of this novel concept isolation room should you manage to find the link, John.

Some time ago, I came across a novel configuration of a single room that provides for both protective (positive pressure barrier) and isolation (negative pressure) requirements. Extensive testing was described at the Hospital Infection Society Conference, Amsterdam 2006. It was specified under Building Note 4 by HEFMA but the link no longer works and I’ve been unsuccessful with chasing down the design. Concept involves an isolation room with a positive pressure anteroom and exhaust from the ensuite room which is entered from the main room. The design is relatively fail-safe and does not need to be manually configured.

Hi John,
See link to the Victorian DOH “Guidelines for the classification and design
of isolation rooms in health care facilities”http://www.health.vic.gov.au/infectionprevention/publications/design_isolati
on_rooms.htmFull PDF at the bottom of the page
As Kevin mentioned in his response dual purpose room are not recommended –
see 2.4 Class A-Alternating pressure (negative/positive pressure) on page 7“Rooms with reversible airflow mechanisms enabling the room to be either
negative or positive pressure are not recommended.(7) Problems with such
rooms include the difficulty of configuring appropriate airflow for two
fundamentally different purposes (see section 5.4), the risk of operator
error, complex engineering and fail safe mechanisms”Regards
