Visits to a hospital by patients or their visitors are almost always a stressful experience, especially the first visit. This stress can rapidly escalate, if they cannot get to where they need to go, quickly – be it to get treatment or to visit a loved one. The difficulty to find way can be compounded for the patient or a visitor if they are less able-bodied person e.g. if they are visually impaired, colour blind, or wheelchair bound etc.
Hence, hospital and clinic designers need to have a comprehensive Way Finding and Signage strategy to assist in efficient functioning of a hospital or a clinic. This is not limited to just providing department names on wall mounted boards with arrows pointing in the right direction. Way finding requires thorough analysis of various aspects of a modern medical facility including
There is a huge variety of signage available in the market ranging from printed wood and plastic panels, small hand-held audio devices to LED and even high definition LCD and plasma displays being used to help people find their way and access information. Hospitals also use interactive computer displays to provide public information including route maps and locations of various functions and general knowledge of interest to the public.
One of the latest developments is the use of environmentally friendly materials such as water based paints, re-programmable LED scrolling signs and as mentioned above use of latest HD TV technology to name a few. The last two can also be programmed to provide assistance in several different languages and signs.
Hospital medical signage, as you can see, has an important role to play in the smooth and efficient running of a modern patient friendly hospital. Get it wrong and you may have a lot of irate patients and visitors, which in turn would affect staff morale and even safety.

Planning Pathology labs including microbiology, biochemistry and haematology should be fairly simple and straight forward. But we know from experience that if careful thought is not given at the design and planning stage, the simplest of things can and most probably will go wrong.
So what do we really need to watch out for? Although designing a hospital is a painstaking procedure best left to the professionals, still the following three basic aspects pertaining to hospital lab design need to be remembered:
Lab Benching
The material and surface are your first consideration. For labs that deal with strong chemicals, Trespa (a brand name and material by Trespa) is the best choice in the market. Within Trespa, there are two types – Trespa Athlon and Trespa TopLab (both registered trademarks of Trespa) .
Athlon is more impact and scratch resistant while TopLab is more chemical resistant.
The other important aspect is the height & depth of the lab benching. Generally recommended height is 920mm for standing and depths are 600mm or 750mm but you will come across situations where an 800mm deep benching is required. This maybe needed to accommodate a deep equipment above or below the lab benching.
You need to remember that with a 750mm deep benching the space below is less than that due to the back panel which hides the services running behind such as electrical cables and water and drain pipes. Make sure you know the height and depth of your under bench fridges and cupboards as well as how big and heavy your worktop mounted analysers and centrifuges are.
Services
The second important consideration is the quantity and type of services required for each piece of equipment dotted around the labs and the need for power, data, potable or special water (distilled, de-ionised, RO), lab gasses, sinks and drainage. Some of these are normally placed at regular measurements around the labs depending on the activities being carried out.
Environment
Depending on chemicals and equipment used, fumes and heat dissipation (such as -70 degree freezers and blood fridges) issues can be significant. This has to be dealt with ventilation and convection cooling/air-conditioning.
While on ventilation, attention needs to be given to the fume cabinets and safety cabinets that require very careful and purpose built exhausts. These can be re-circulating (requiring specific filtration) or exhaust type that take the extract out to a certain level outside the building.

Of all the clinical areas in any hospital, X-Ray, CT, and Fluoroscopy need much more planning and co-ordination than any other thing imaginable. This is mostly due to the fact that the equipment used and its implications on the building structure and services is much more complex with the exception of the MRI. We will deal with MRI in another article and will only discuss factors to be considered while designing an X-Ray room, which, in principle will hold for the CT & Fluoroscopy rooms as well.
Room Dimensions, Entrance and Access Route
As X-Rays are large and heavy pieces of kit, first and foremost consideration should be: Can the largest part be brought to its intended location from the entrance via any corridors and lifts? You should consult the equipment manufacturer’s specific model pre-installation guide before you make the purchase and involve an architect to ensure the kit will pass through all doors and corners and will not get stuck in the lift doors (if the location is not on ground floor)!
The manufacturers will advise of the critical room dimensions for the equipment to work and intended clinical procedures to be carried out successfully with regards to the prevailing local regulations.
Structure
As clinicians will know, X-Ray equipment consists of the floor mounted table, wall mounted chest bucky and (mostly) ceiling mounted X-Ray tube. In addition, there is the operator’s control console and the generator cabinet with a couple of Emergency Stop buttons.
The ceilings and walls must be strong enough to not only take the weight of these items but have proper pattresing to attach the equipment as recommended.
All these pieces of equipment require power and interaction hence cables run between these items. With the table being in the middle of the room, there is a need for having a floor trunking with removable lid between the wall and the table to house any cables. The exact location, dimensions and details of this trunking must be established with the equipment manufacturer. If your hospital is a new build, you need to pass that information together with the floor loading and ceiling slab deflection and minimum vibration requirements to your structural engineer and the architect. If it is an existing building, you are best advised to establish the above requirements and involve your builder, architect and a structural engineer before purchasing the equipment.
Most probably, the services between the floor mounted equipment and the ceiling mounted tube will be run on surface mounted floor to ceiling wall trunking with removable lid.
Make sure that the ceiling is strong enough to take the load of the tube and that the area above does not have any equipment or plant that makes vibrations. In addition, the veiling mounted tube glides along the length of the table on two rails. These rails are mounted on secondary steel attached to the ceiling. This secondary steel is usually UniStrut or MarsStrut which are registered trademarks and you will normally employ specialist sub-contractors to install these as the radiographic equipment suppliers work once the room is complete with all services available, secondary steel installed and floor and wall trunkings and high level cable trays in place and room finished to builder’s clean.
Services & Environment
Will suffice to say that you will require power and data (check if broadband) as per the manufacturer’s specification. The equipment will generate significant heat and hence cooling will also be required. Make sure you ask whether humidity control is also required as generally people do not understand differences between comfort cooling, air-conditioning and humidity control.
There will usually be an emergency stop button at the control console and another possibly near the table.
The actual location of all services and equipment will have to be precise according to the supplied drawings provided specifically for your project by the equipment manufacturer.
Radiation Protection
Depending on the equipment, room size and location of the equipment and adjacent areas, a qualified Radiation Protection Advisor must be employed to advise on what materials must be used for walls and doors (and floor and ceiling if required) to ensure the X-Ray equipment radiation is contained an does not harm anyone. (The operator in the room operates from behind a lead screen).
I hope that the above main points will help you think and plan ahead when you want to add/update your next imaging room and will allow you to quiz manufacturers, builders, architects and engineers involved to give you the best and most effective and economical solution for your money!
As always I would love to hear your feedback, comments and your experiences – good or (God forbid) bad.

Designing an operating theatre outlines the intricacies of the hospital design process. An operating theatre suite consists of the Theatre, the Anaesthetic room, Scrub room and the Dirty Utility (or just Utility) room. We will look at planning just the Operating Theatre itself in this hospital design guide article.
The size and room dimensions vary but as an indication it should be about 7 meters wide by 8 meters long (56 square meters).
Any surgeon will tell you that over-riding principles while designing an operating theatre are:
There are different arguments for either having all equipment and instruments on mobile trolleys to allow 100% flexibility on use of the theatre and ease of cleaning the theatre versus mounting a great majority of equipment on ceiling mounted theatre pendants. The ceiling slab must be able to hold the weight of the theatre lights, pendants and the equipment if mounted on the pendants. It is highly recommended that you check with your structural engineer.
Ceiling Mounted Equipment:
1. Pendants
Expect a Surgical and an Anaesthetic Pendant in any theatre which have power, data and various gas outlets. There are several major suppliers on the market with numerous different types. Pendants can be rigid, rigid, retractable or fully articulated. Theatres require fully articulated pendants for maximum flexibility. A lot of co-ordination is required between medical gas, electrical, and pendant trade contractors together with electrical, mechanical and structural engineers/consultants while installing pendants to ensure all structural steel support is in place, gas pipes are properly connected and power and data cables run at the correct programmed dates.
Various life saving equipment must be powered off Un-interruptible Power Socket(s) – UPS, in case of power failure during surgery.
2. Theatre Lights
There used to be the Gas Discharge lights or Halogen lights. Aspects to consider were bulb life, costs associated and Theatre down time while bulbs were changed.
There is a new kid on the block in the last couple of years – LED technology. About 30% more expensive compared to the existing technology but very long life bulbs (over 20,000 hours), ease of maintenance (couple of minutes to replace an LED), cheap cost of replacement (fraction of older technology) and ability to vary light temperature hence helping to diagnose cancerous cells etc.
Theatre Lights must be backed up by a battery back up in case of power failure during surgery. Suggested time can be 3 hours back up. Note that general lighting and emergency escape lighting should also be on similar battery/UPS back up time.
3. Camera
In a teaching facility, a camera (now a days High Definition Camera) and microphone is also required for one way video (from Operating Theatre to Lecture Theatre and/or Seminar Rooms) and two-way audio for surgeons and students to communicate. The camera can either be installed in the handle of the main Theatre Light of installed on a separate ceiling mounted arm. Consider all implications for power and data transfer (HD requires much higher bit rate transfer). Consider a wireless Reality TV / Big Brother style microphone on the surgeon to allow freedom of movement.
In Orthopaedic Theatres you would need to consider the largest ceiling mounted item – The Laminar Flow or the Ultra Clean Ventilation (UCV) Canopy. This item will need a separate article as we are planning a general Theatre in this article.
Wall Mounted Equipment:
1. Surgeons Panel
The panels can the older style steel type or the more current Membrane Type panels which allow ease of cleaning/disinfection. The membrane can be made anti-microbial by inclusion of silver nitrate. A newer version of panels can be touch screen however its not proving very popular as it can take several screen touches to reach a certain function, whereas other two panel types have all the buttons available in the panel.
For ease of cleaning and aesthetics, the panels should be flush mounted.
Note that all the pendants, theatre lights, general lights, gas alarm panel, IPS/UPS, and warning signs for X-Ray in-use / Laser in-use signs outside Theatre, air sampling ducts, clocks etc need considered and carefully co-ordinated among the trade contractors and design consultants for services and wiring.
Floor Mounted Equipment:
1. Theatre Table
Generally these are rechargeable and don’t necessarily require power socket close by.
2. Trolleys
Trolleys are used for instruments and equipment such as video endoscopes and anaesthetic equipment.
We mentioned ease of cleaning at the start. To enable this the walls should have special plastic enamel paint to allow chemical cleaning if required in case of disinfection. The ceiling is generally constructed of plaster board or special metal to ensure it is air-tight and easily cleaned.
Airflow regime is an important part of moving the air from clean areas towards dirty and out of the Operating Theatre suite to ensure the Theatre is the most clean environment for operating on the patients.
I trust the above has given you some basics to consider when planning your next operating theatre.
