With the current drive towards improving efficiency and saving costs across hospitals, barn operating theatres have become a new and innovative way to use theatres.

The term ‘barn theatre’ refers to the open-plan design of the main surgical area, where each patient is treated in a dedicated space alongside the next patient, with a specialised air canopy over each station to prevent the spread of infection. The barn theatres have adjoining anaesthetic rooms and traditional recovery areas. Benefits of barn theatres include lower infection rates, improved safety and enhanced team working.

However, for multiple operations to take place in a single open space, it is essential that the ventilation system provides the protection against cross-contamination that would normally be provided by the intervening theatre walls. It’s also essential that the correct doors are specified to maintain the correct room pressures and prevent the spread of infection.

The open plan design of the barn theatre can offer lots of potential and numerous benefits, including:

– Opportunities for enhanced team working
– Greater peer awareness of contemporary surgical practice and standards
– Improved supervision for non-consultant surgeons
– Opportunities to develop non-doctor anaesthetists in a safe environment
– Efficient space utilization
– Reduced infection rates through improved theatre discipline.

Although the concept of the barn theatre is still relatively new, there have been an increasing number of barn theatres completed within the past few years; including Wrightington Hospital in Lancashire, Broadgreen Hospital in Liverpool and Chase Farm Hospital in London. There are a few other similar projects, including those at Salford Royal Hospital and the Royal Orthopaedic Hospital in Birmingham.

Dortek have supplied specialist doors to a number of these theatres, with Wrightington hospital and Chase Farm Hospital being the most recent. Dortek hermetic sealing sliding doors were specified on the recent Chase Farm project to provide maximum hygiene, ease of access and control of air leakage. Our hermetic doors have a 99% air tight seal, which helps prevent air leakage and reduce the risk of cross contamination in these areas. The doors and privacy vision panels were also supplied with lead and laser protection and touchless automations. The hygienic GRP construction of our hospital doors gives them a smooth, non porous and easy to clean surface which is ideal for infection control areas. Unlike timber doors, Dortek hygienic GRP doors have no natural seams, voids or crevices which can harbour bacteria. They are also free from hard to clean lips, joins and ledges (even around vision panels).

In essence barn theatres have numerous benefits, for orthopaedics surgery in particular and are designed to help hospitals treat more people more quickly, safely and cost-effectively. The unique concept means that more operating theatres can be put into smaller spaces with reduced members of operating staff. With multiple surgeons working alongside each other it’s also an ideal opportunity to share best practice and standards.

In the following video, Dr Alan McGlennan, medical director at Chase Farm Hospital, talks through the benefits of the new barn theatres in more detail. https://vimeo.com/281403947

Dortek has recently completed a project for a new state of the art cleanroom facility which will enable a leading international gene and cell therapy company to expand its bioprocessing operations and manufacturing capabilities.

From the outset Dortek were appointed to work alongside the project team to design, manufacture and install specialist hygienic GRP doors for the facility. Dortek doors were installed into GMP cleanroom suites, production areas and quality control laboratories.

The specialist areas have been designed in full compliance with MHRA regulations and conform to ISO cleanroom standards. This includes the use of zoned HVAC systems to maintain the segregation, cleanliness, air pressures and other environmental controls.

Choosing the correct door system is a critical part of the design within these facilities as the doors will dictate compliance with standards, ease of traffic movement, hygiene, fire regulations and balance of air movement. As well as this, doors must be seamless, waterproof, resistant to cleaning regimes and free of voids and organic material such as wood where bacteria could multiply.

Dortek supplied 160+ hygienic door systems, some doors had hermetic sealing for air pressure differential and VHP fumigation control. Doors were also supplied with fire and smoke test certifications. More than 60% of the hinged and sliding doors are automated and interlocked, actuated by touchless sensors for greater facility control against cross contamination.

Dortek hygienic GRP doors are completely free from cracks and joints making them the most hygienic solution. The moulded seamless construction of a Dortek door makes it easy to clean, non-absorbent and able to withstand the intensive cleaning regimes which are often used in cleanrooms and research laboratories.

Dortek’s Marketing Manager, Sheree Headspith, said: ‘We have built a strong reputation for supplying our specialist hygienic GRP doors to the biotechnology industry and the number and quality of projects we are being specified on continues to grow. We are delighted to be able to offer our expertise and knowledge on doors for these highly specialist facilities which are required to meet strict regulations and high standards of cleanliness.’

Here’s some advice about key design considerations when specifying doors in hospitals and other hygiene critical facilities.

Since microorganisms can be transmitted by contact, choosing the right doors can make a huge difference to infection control. Hospital doors can be a major source of contamination as they are the piece of equipment which is touched the most by patients and staff. Hospital doors are also vital for controlling clean air and traffic flow. This is why it’s crucial that the correct door is chosen as it can significantly affect the risk of infection.

Making the right door choice

When specifying hospital doors, considering the following points will not only help infection control, but it will also ensure building regulations are met and the doors operate efficiently, with a long, trouble-free lifespan.

• Hygiene performance
• Inorganic door construction
• X-ray and laser protection
• Hermetic sealing for clean air control
• Fire and smoke regulations
• Automations and accessibility
• Strength, durability and maintenance requirements
• Sound insulation
• Life cycle costs.

Choose Hygienic Door Materials

One of the most important aspects of a successful infection control policy, is choosing the correct materials for both the construction of the room and the components within it.

The Health Building Note 00-09: ‘Infection control in the built environment’ offers valuable guidance for architects and specifiers. ‘Doors should be cleanable, that is, smooth, non-porous and fluid resistant’. This is particularly crucial in areas where infection control is paramount.

Hospital doors should be carefully selected to ensure they are constructed using an inorganic hygienic material such as GRP (Glass Reinforced Polyester). Doors should also be easy to clean and resistant to moisture and disinfection procedures. A smooth construction should be defined as seamless with no texture, voids, reveals or laminated components which can harbor bacteria.

Specifying hygienic GRP doors for infection control

Hygienic GRP hospital doors are manufactured from a high technology moulded composite which has been independently tested. Laboratory tests conducted by IMSL (Industrial Microbiological Services) prove that hygienic GRP doors help prevent bacterial and fungal growth. Dortek Hygienic GRP doors have been independently tested by IMSL for resisting infections such as MRSA, Aspergillus Niger, Staphylococcus Aureus & E Coli.

Critical to the doors hygienic performance is its one-piece moulded GRP construction with no seams, joints or voids where bacteria, dust or dirt can build up undetected. The inorganic construction and water repellency of Dortek doors provides no sustenance for harmful microorganisms. Hygienic GRP hospital doors have no lips, joins or edges (even around vision panels). They have an easy to clean surface which is unaffected by moisture or common cleaning chemicals and disinfectants. Colour is also built into the gel coat of the door to provide continuous long-lasting protection, which is not reduced by impact damage.

Hermetic sealing for clean air control

Hermetically sealing doors should always be considered for reducing cross contamination through air flow in high risk areas such as operating rooms and patient isolation areas.

Hygienic GRP hospital doors can be supplied with hermetic sealing options for controlling air. Hermetic hygienic doors have a unique patented track system so it seals perfectly against the floor and frame. The efficiency of the seal has been officially tested and results show it to be over 99% effective thus helping to reduce the spread of airborne infections, cross contamination and air handling costs.

Third party tested fire ratings and lead protection

In certain areas of a hospital, evacuation in the event of a fire is almost impossible. Intensive care units and operating theatres are obvious examples. Fire doors are often the first line of defence in a fire and their correct specification can be the difference between life and death for building occupants.

Hygienic GRP doors have a vermiculite-core and can provide up to 4 hours fire protection. Vermiculite is a mined mineral rock, which is classed as non-combustible. Hygienic GRP fire doors have been third party tested and have a patented concealed intumescent strip built into the door. This maintains a smooth seamless profile ensuring that there are no seams or ledges where dirt and germs can gather.  It is also ideal for high traffic areas as it never comes lose or needs to be replaced. Hygienic GRP doors can also be supplied with x-ray ratings and sound insulation for the added protection of patients and staff.

Touchless automations to reduce cross contamination

Hygienic GRP Doors can be automated to provide hands-free entry and further reduce the risk of infection. The doors use an intelligent automation which is key for user safety. The automations react to the smallest obstruction and photo sensors stop the door from closing onto passing traffic. Doors can also be provided with access control systems, locking and interface with BMS (Building Management Systems) for extra security.

Durability and life cycle costs

With sustainability at the forefront of the healthcare sector, doors which require frequent servicing or redecoration should always be avoided. Hygienic GRP doors are up to 42% lighter than wood or laminate doors. This removes any need for expensive maintenance work or replacement due to excessive wear on hinges and closers. GRP is an exceptionally strong and heavy-duty material which gives it the lowest whole life cycle costs in comparison to other alternatives.
