General Planning Considerations

Sterilisation department in a hospital

The sterilisation department in a hospital is known by many acronyms, e.g.:

CSD Central Sterilisation Department

CPD Central Processing Area

SSD Sterile Service Department

TSSD Theatre Sterile Service Department

TSSU Theatre Sterile Service Unit

CSSD Central Sterile Service Department (the most widely used term in the South African context)

Location and functional relationship

Functional relationships to other departments

See Figure 1. The CSSD should be centrally located with ready access to all related service areas, such as the ICU, in-patient units and emergency unit. The department should also have direct access, either horizontally or vertically, to the operating theatres.

Deliveries and transportation routes

Trolleys are used as mode of transport for both receivables and deliveries. In order to cater for the high volume of trolleys to and from the CSSD receiving and dispatch areas, the entry/exit points should ideally be separated to create a uni-directional traffic flow and also to avoid cross-contamination through the division of the clean and dirty material.

Access for plant and equipment maintenance

Plant and equipment in service areas would need access from outside the CSSD, in order not to compromise the desired level of cleanliness in the unit. In some situations direct access between the plant area and the steriliser is required in order to allow access for maintenance staff to the equipment controls in the CSSD area side.

Figure 1: Departmental relationships (IUSS:GNS Adult Inpatient Services)

Primary function of a CSSD

The primary function of a CSSD is to provide an efficient, economic, continuous and quality supply of sterilised items, when needed, to all patient-care service points in the hospital, and to receive returned contaminated items for cleaning. This process is generally referred to as the “decontamination life cycle” (see Figure 2).

Figure 2: Decontamination life cycle

Activities in a CSSD can functionally be sorted under the following primary zones:

Dirty Decontamination Zone
Clean IAP (Inspection and Packing Zone)
Sterile Clean Zone

In addition to the above primary zones, supporting activities are accommodated in the CSSD.

Support zone

In order to identify the functional relationship between the various spaces, the convention is used throughout this guide to indicate the respective zones in the following colours:

In order to create a work space for maintaining a clean environment suitable for handling sterile articles, access to the red, blue and green zones is restricted and subjected to “red-line” principle.

In addition to the above, the red area (decontamination zone) is divided with a hard barrier from the IAP area, in order to prevent contaminated particles from freely entering the relatively cleaner IAP area. This barrier could be a solid brick wall, or glass wall.

Activities comprising the decontamination cycle should allow a progressive work-flow pattern that commences with a “dirty” entry and receiving area, proceeds to a cleaning, decontamination and drying area, into a sorting and packing area, through to sterilisation and cooling area, to finish with sterile storage, distribution and exit areas.

Figure 3: Work flow through the primary zones

Activities in a CSSD

The main activities of the “decontamination life cycle” taking place in a CSSD can be listed as follows:

receiving of soiled (and contaminated) returns
cleaning of trolleys
sorting returned trays

sorting, disassembling, cleaning and drying of all returned medical devices
checking functionality and cleanliness of cleaned medical devices
assembling, packing and wrapping of trays
sterilisation
cooling of sterile packs
storage of sterilised items
dispatching of orders
quality control
maintenance
record keeping
receiving new supplies.

These activities can be classified under the following functional areas:

Decontamination

Decontamination involves the use of automated and manual cleaning to remove harmful blood-borne pathogens on the surfaces of equipment and instruments. Soiled items for re-use (medical devices, textiles and equipment) are received in the sterilising department after use in the various clinical departments. These could be operating theatres, emergency department and various wards. Medical devices, equipment and other contaminated articles will be sorted, disassembled, pre-rinsed and cleaned in the decontamination/dirty area. Used linen is put into linen bags and sent to the laundry. Waste items are sorted into suitable containers, according to policy, for appropriate disposal methods.

If items are heavily soiled a manual washing procedure will precede the automated cleaning process by washer-disinfectors. For manual cleaning, a double- (two-) sink arrangement is optimal, one for cleaning and one for rinsing. Automated washers or washer-disinfectors can be provided as single or double-door designs (the latter to allow for physical separation of the dirty and clean areas of the decontamination area).

Inspection

Decontaminated medical devices and equipment are visually inspected for functionality, damage and cleanliness according to required standards, the manufacturer’s instructions and written protocols.

Packing

Decontaminated instruments, equipment and other articles are sorted, assembled, counted and packed prior to sterilizing.

Sterilisation

Sterilisation is a defined process used to render a surface or product free from viable organisms, including bacterial spores. Depending on the product this procedure could vary from steam sterilisation, dry heat sterilisation, to low temperature sterilising processes.

Storage

Sterile items are stored in a clean controlled environment to prevent re-contamination before use.

Workflow

Design solutions should follow work-flow principles, separating dirty and clean areas. The workspaces in the decontamination and clean areas should be designed as open-plan work areas subdivided by benches and/or equipment into functional work areas. These work areas should be arranged to allow for a progressive work flow that commences with a ‘dirty’ entry and receiving area, proceeding to a cleaning, decontamination and drying area, into a sorting and packing area, through to a sterilisation- and cooling area, with sterile storage, distribution and exit areas completing the process.

It is critical to the functional efficiency and safety of the CSSD that these spaces are sequentially linked for one-way flow-through of instrumentation. The separation between the dirty area, where soiled goods are collected, and the clean area where washed and disinfected instruments are inspected, sorted and packed, is realised by a high throughput pass-through washer disinfector barrier.

Treated instruments are unloaded and managed directly in the clean packing area by different staff.

General design considerations

Design for infection control

The design of a CSSD plays an essential role in addressing infection control issues to minimise the risk of infection transmission.

Planning and design features to support infection control should include the following:

Restricted/controlled access
Unidirectional work flow, progressing from dirty to clean to sterile areas
Controlled air flow with positive air pressure from clean to dirty areas
Containment of steam and moisture, preventing potential contamination of stored sterile articles.
Building and layout details that would facilitate easy cleaning
Selection of suitable building materials and finishes
Selection of fixtures, fittings and equipment with suitable detail, materials and finishes for easy cleaning, and prevention of build-up of harmful organisms
Adequate facilities for cleaning and waste management
Access to the area should be limited and controlled. This should prevent any unauthorised person from entering the area without permission
Staff/visitors should have access to hand-washing facilities, separate from those used for cleaning devices, before entering or leaving the areas.
The flow of both staff and equipment must allow no cross-over of soiled and clean materials
The operating procedure for infection control in a CSSD falls outside the scope of this guideline.

Design for Occupational, Health and Safety

Planning and design features to support occupational health and safety include the following:

Selection of floor finishes with a non-slip finish
Selection of fixtures, fittings and equipment with suitable detail, materials and finishes to prevent personal injury through accidents or misuse
Provision of suitable and adequate facilities to support and encourage a high level of personal hygiene, with special reference to hand hygiene
Provision of adequate dispensing points for the appropriate personal protection items (PPE) for the specific area to enable strict enforcement of PPE requirements in the protection of healthcare workers, especially as preventive measures against HIV aids
Top-loading, worktop equipment should be accessible to staff members of all heights
Ill-considered dimensions and layouts of fixtures and fittings could have a significant negative effect on occupational health and safety of staff.

As the requirements of the Occupational Health and Safety Act will apply, this section needs to be read in conjunction with the OHS-related guidelines.

Design for change and technology

Although it is difficult to predict future trends in CSSD technology, it is advisable to allow some flexibility and adaptability in space requirements, electrical consumption and layout, and also in air-handling capacity. Current trends that need to be considered are the following:

The increasing complexity of surgical procedures requires more intricate equipment and instruments that need specialised care and handling during the sterilisation procedure
Integrated computerised tracking facilities have become widely used and have become an essential tool in the validation of the sterilisation process
Changing staff-flow patterns due to changing work-flow patterns as a result of procedural and/or equipment innovations
Design towards sustainable architecture, i.e. water-saving equipment, and equipment with reduced toxic emissions. Constant improvements and innovations lead to products that run more economically and reach a higher level of environment compatibility
The facility should be able to reasonably accommodate access and positioning of possible outsize equipment. Consideration for this possibility should be given from (and including) point of delivery to point of positioning
It is advisable to allow capacity for extra machinery in the event of increased production demand.

Ergonomic and user-comfort considerations

Sterile services departments should be designed to protect staff from avoidable risks of injury. Badly designed elements such as height, depth and design of workstations and counters, shelving and the layout have an impact on the occupational health and safety of staff. Workspaces should therefore be sufficiently flexible and adaptable to accommodate adequate working space for individual comfort, and to reduce any unnecessary physical stress or risk of injury to the body from any repetitive and/or periodic actions such as lifting, pulling, pushing, etc.

Ergonomics considers the understanding of human-equipment interaction and design to minimise safety risks and achieve the optimum use of equipment. When particular high risks are identified, these should be minimised when designing the facility – while providing good lighting (preferably natural light), adequate ventilation, plenty of space, and comfortable humidity/temperature conditions. Workbenches and chairs must be height-adjustable, allowing staff to adopt the correct posture when sitting or standing.

Enough space must be available to allow for organisation of the workspace. All materials, for example those in the packing area, should be located within easy reach of the workbench (packaging materials, indicators, etc.). A similar concept should apply to device-sorting or manual-cleaning areas. There should be adequate space to manoeuvre, queue, and unload trolleys or other means of transportation. This will allow not only for good ergonomics but also for efficient work practices.

The provision of a pleasant interior environment can contribute to staff morale. Temperature and humidity control (air-conditioning), in particular in areas where heat-associated equipment (such as steam sterilisers and thermal washer-disinfectors) is used, is preferred. Provision must be made for adequate heat extraction systems from heat generating equipment such as autoclaves and instrument washers. This should be done as close to the source as possible i.e. above autoclave doors and instrument washers. This heat source can be utilized to pre-heat water going to the boilers. Consideration should also be given to ensure there is adequate lighting (preferably natural) and noise control.

For larger facilities, provision may need to be made for managers’ offices, general staff areas (for eating and drinking) and storage areas that are separated from the decontamination area. Good interior design also contributes to staff morale. The aim should therefore be to create an attractive and cheerful environment throughout the department.

Sound

Noise must be controlled

A threshold of 60dBA (decibel) must not be exceeded
The walls and ceilings should be made of absorbent materials so that they do not reflect sound
Insulation of sterilisers and washer-disinfectors in technical walls will reduce the noise level
Offices should allow confidential discussions to take place in privacy, away from noisy mechanical or high-volume human areas.

Natural light

Natural lighting is highly desirable, especially in the work areas, and should be used wherever possible, especially in areas such as the cleaning and packing areas. However, direct sunlight on work spaces should be avoided.

Natural ventilation

Natural ventilation through opening-section windows should be limited to offices and staff rooms. However, this is not recommended as it could promote contamination of the internal space by outside sources. Mechanical ventilation should be provided through the remainder of the CSSD, with good primary and secondary filters which must be monitored with differential manometers linked to an alarm system.

Communication

Provision must be made for communication systems to minimise the passage of staff to and from the clean zone. Glass partitions, communication panels, IT and video links for data transfer, intercom and telephones can serve as appropriate means of communication.

Glass partitions should be used to permit observance of the activities within the clean zone (from the outside) without having to enter it. The glass panels must be of a non-opening design and must be waterproof and flush-mounted.

CSSD Area Determination

Determination of size and layout

The size of a CSSD in a hospital is unique to that hospital, as the size, layout and function of a CSSD are defined in the Operational Policy Statement that guides the operational management of the hospital. The operational policies specific to the CSSD precede sketch design stage. These policies are developed by the project team in consultation with health; service stakeholders, who should have the knowledge and experience to analyse the various processes in and related to the CSSD.

These operational policies define the “What, How, When, Where, Who and With What” of any activity and/or process and are major space determinants which could significantly affect the planning and design of the CSSD, as they can have an impact on the size, configuration and the nature of accommodation. Operational policies will vary from unit to unit depending on a wide range of factors, both external and internal to the CSSD.

Determining factors external to the CSSD

Examples of these space determinants could include the following:

number of theatres/case mix
surgical procedures
extent of storage in the theatres and wards
distribution system that will be used (vertical, horizontal, trolleys, lifts)
amount of space needed for waste management
processing needs for re-usable textiles (receiving, transporting, collecting, storing)
staff facilities to be shared with adjacent departments. See annexure A for a generic set of Standard Operating Policies (SOP) for a typical sterile service department.

Determining factors internal to the CSSD

Examples of these space determinants could include the following:

types of processing equipment to be used (washer, washer-disinfectors, single- or multi-chamber washers, ultrasonic cleaners, endoscope processors)
types of packaging to be used (disposable wraps and pouches, re-usable wraps, rigid containers
echnology to be used for sterilisation (high temperature or low temperature sterilisation, other chemical sterilants, steam)
anticipated inventory storage
anticipated volume of consumable supplies
type of documentation and record-keeping system to be used (manual vs computerised)
instrument inventory
equipment inventory
projected workload
staffing structure – number of offices
staffing policy - number of staff to be accommodated
types of cleaning equipment selected such as multi chamber or single chamber
number of sterilisers and whether front or double sided loading
emergency sterilisation requirements.

CSSD area determination

Hoët (1989 cited in AFS Working Group, 2008b, p.281) has estimated the following ratios as a broadbased calculation of CSSD space:

0.7 m²/bed from 0 to 300 beds
0.6 m²/bed from 300 to 600 beds
0.5 m²/bed for more than 600 beds.

Based on these ratios, the following table can be compiled:

Table 2:Ratio of hospital bed to CSSD area

BED SIZE	CALCULATION	SURFACE AREA
200 BEDS	0.7 m² /bed	210 m²
400 BEDS	0.6 m² /bed	240 m²
600 BEDS	0.5 m² /bed	300 m²
800 BEDS	0.5 m² /bed	400 m²
1000 BEDS	0.5 m² /bed	500 m²
1200 BEDS	0.5 m² /bed	600 m²

AFS Working Group (2008b, p.291) states that the CSSD has few internal corridors, the commonly used net to department functional factor adopted is 1.30. The 1.30 factor anticipates that the internal circulation must be added to connect functional areas and individual rooms. This minimal surface area required can be estimated as being 200m² useful and 260m² net floor areas.

Based on the above assumption, AFS Working Group (2008b, p.291) calculates the useful surface area using the MSO ratio based on the number of beds used for Medical – Surgery – Obstetrics (MSO), using the following calculation basis:

Table 3: Ratio of MSO to CSSD area

MSO – NR OF BEDS	USEFUL SURFACE AREA/BED	USEFUL SURFACE AREA	NET SURFACE AREA
< 200 BEDS	200	200 m²	260 m²
200 – 300 BEDS	1,5 m² /bed	300 – 400 m²	400 - 520 m²
300 – 400 BEDS	1,2 m² /bed	350 – 420 m²	450 – 550 m²
450 + BEDS	1,0 m² /bed	450 m²	600 m²

Studies done by Putsep and Cowan (1983, p.8) produced the following ratios depending on the ‘active’ nature of the bed.

Table 4: Comparative recommendations for estimating the size of a CSSD (Putsep and Cowan,1983, p.8)

NR OF BEDS	SCANDINAVIA	BELGIUM	NETHERLANDS	RSA¹
	m² PER BED
200 BEDS	1,1 m² /bed	0,6 - 1 m² /bed	0,7 m² /bed	1,0 m² /bed²³
350 BEDS	1,1 m² /bed	0,6 - 1 m² /bed	0,6 m² /bed	1,0 m² /bed
500 BEDS	1,1 m² /bed	0,6 - 1 m² /bed	0,5 m² /bed	1,0 m² /bed
750 BEDS	1,1 m² /bed	0,6 - 1 m² /bed	0,4 m² /bed	1,0 m² /bed

Based on the above data, the areas are as follows:

NR OF BEDS	SCANDINAVIA	BELGIUM	NETHERLANDS	RSA³
	TOTAL AREA
200 BEDS	220 m²	160 m²*⁴	140 m²	200 m²
350 BEDS	385 m²	280 m² *	210 m²	350 m²
500 BEDS	550 m²	400 m² *	250 m²	500 m²
750 BEDS	825 m²	600 m² *	300 m²	750 m²

As the schedules of accommodation on which the above analyses are based have not been included in the study, the equitability of the comparisons is in doubt.

It is however; clear that the size of a CSSD cannot be generically determined on the basis of statistics or averages. Every CSSD has its own set of area determinants that need to be logically evaluated in order to arrive at an area that is the optimal combination of functionality and cost effectiveness.

Proportional allocation of space in a CSSD facility

Table 5: Space allocation in a CSSD (Putsep and Cowan,1983, p.9)

AREA	NUFFIELD PROVINCIAL HOSPITALS TRUST (1963)	ESTIMATED AVERAGE – SWEDISH PRACTICE	NORWEGIAN RECOMMENDATIONS (1978)	HOET (1981)

STERILE SUPPLY				25
STORE DISPATCH	16	29	25
BULK STORE	11	14	20	15
STAFF AREA OFFICE HOUSEKEEPING	23	10	15	15

AFS Working Group (2008b, p.291) states that the areas within the CSSD can be sub-divided as follows:

Receiving: 10% of the surface area

Decontamination: 25% of the surface area

DIRTY 35% IAP 35% of the surface area
CLEAN 35% Sterile Storage 20% of the surface area
STERILE 20% Annexes: 10% of the surface area

SUPPORT 10%

If the generic plan used as basis for this study (LAYOUT 2.1) is subjected to an area analysis, the following table can be compiled (TABLE 4.5) for an autonomous (support services not shared) CSSD of 600m². If staff facilities and corridors are shared with another department (e.g. theatre department), the CSSD’s size reduces to 450m² as per TABLE 4.6, illustrating the difficulty in achieving universally applicable areas, and the effect of hospital-specific policies.

It is significant that the percentage of total areas of TABLE 4.6 compares favourably with the AFS Working Group’s recommendations.

Individual Space Requirements

CSSD Layout Unpacked

Due to the uni-directional sequential nature of the work flow in the CSSD, activities are interrelated and inter-dependent. It is, therefore, critical to the functional efficiency and safety of the CSSD that those areas are sequentially linked for uni-directional flow-through of instrumentation, with no room for back tracking.

The above work flow and interrelationship between the adjacent areas dictates the characteristics of each space. In order to discuss each area individually, it is necessary to have a base plan as a reference point. The typical floor layout based on a 600m² unit will be used for this purpose.

Circulation space for the free and unhindered manoeuvring, loading and unloading of steriliser trolleys

Exhaust over the front of the steriliser doors to extract heat and steam, in order not to compromise the HVAC air flow and temperature. An extraction system which is activated by the autoclave door opening rather than a constant extraction system should be considered
It is generally advisable to install two smaller autoclaves rather than one large one
An extra autoclave should be provided to cater for exceptional demand, maintenance and breakdown
A clear space of 2m in front of the autoclave is needed to facilitate the handling of loading trolleys
No partition wall should be closer than 750mm to any autoclave

The autoclaves must be well insulated. The emission of heat to the environment must be minimal, and adequate extraction facilities should be provided to remove hot air and steam from the autoclave at a rate equivalent to 15 air changes per hour
Require separate installation and accommodation according to manufacturer's recommendations
The size of the area will be dependent on the number and type of sterilisers installed and, importantly, whether the sterilisers are single- or double-sided
A duct enclosure can also minimise heat build-up within the workroom. An exhaust over the front of the steriliser(s) should be considered, to extract both heat (cabinet) and steam (opening door).

Fixtures, Fittings and Equipment

The maintenance area in particular should be well ventilated by natural means assisted by mechanical extraction if necessary. Note that this only achievable with single door autoclaves. Where double door autoclaves are used care must be taken to identify an access point from within the unit, which causes least disruption.

Fixtures, fittings and equipment

As per manufacturer’s specifications.

Services

As per manufacturer’s specifications.

Building and Services

Building components, materials and finishes

Floors

Carpet or similar soft flooring should be avoided.

Impermeable, non-slip floor covering is recommended. PVC welded sheet vinyl, coved up the wall, ensures a watertight, hygienic surface which will withstand daily cleaning.

Small-diameter coving puts undue stress on the floor vinyl and is prone to cracking over time. Largerdiameter coving has the added advantage that in certain cases it prevents trolley wheels from being pushed against the wall, acting as an added wall protection.

Walls

Walls should be washable, preferably cladded by welded sheet vinyl. Durable polyurethane wall finishes are rapidly appearing on the market and selected products could also be suitable in certain circumstances.

Walls should be adequately protected against damage by loose equipment and wheeled traffic by buffer rails and corner guards, which should be appropriately sited to reflect the specifications of trolleys in use. Protruding elements of different trolleys are of varying height. This should be considered in the selection of wall protection.

Ceilings

Suspended modular ceilings with inlay panels are not suitable.

A minimum below-ceiling height of 2 800mm is recommended. If ceilings are lower, precautions must be taken with respect to the arrangement and number of air vents as well as to the temperature of the air circulated. This below-ceiling height will have implications for the noise level prevailing within the CSSD.

Ceilings should be:

washable, impermeable and non-porous
sealed to prevent ingress of airborne particles or other contaminants from the ceiling void

resistant to humidity in zones where steam and moisture may be encountered.

Windows

The walls and partitions must feature as many glass panels as possible to facilitate supervision, and also to create a feeling of spaciousness.

Windows to the outside are highly desirable in the working areas. However, these windows should be non-opening, sealed and preferably flush fitting, in order to prevent the windowsills from being used as storing space. If this is unavoidable, the sills should be angled.

Doors

Doorways should be positioned to allow trolley movement, and doors and corridors should be wide enough to accommodate trolley turning circles and protruding trolley fittings.

Door frames and door leaves should be designed and finished with protection cladding and bumper rails to withstand the inevitable bumps by trolleys.

Doors should be adequately sized to allow clear passage of current as well as possible future equipment.

Automatic/semi-automatic doors make it easier for collection and distribution of trolleys. If not automated doors should be self-closing. If the design allows it, doors should open towards the higher pressure side where possible to overcome problems with weakening door closers, which may lead to lock-outs.

Vision panels should be provided.

Hatches

Where hatches are required to accommodate transfer of articles between the decontamination area and IAP area, for example, they should have purpose-designed close-fitting sections to preserve the integrity of the ventilation system.

Ducts

Service ducts should:

allow easy access and should ideally not be in the clean and sterile areas
be protected as far as possible from unauthorised entry
allow for eventual removal and replacement of major plant and equipment
allow enough space to access equipment for cleaning or replacement.

Fixtures, Fittings and equipment

The selection of equipment should be fully coordinated with the facility’s design in order that utility and space requirements are considered during design development.

Sterile storage shelving

Packs should be stored away from direct sunlight and water and should not be stored next to or under sinks, or on the floor where they are likely to get wet or damaged. Sterile packs should be stored at least 250 mm above the floor, and 450mm below the ceiling or sprinkler heads and at least 50 mm from side walls to allow for air circulation in the room and to prevent contamination during cleaning. The shelves should be 400mm apart and be adjustable in increments of about 50mm.

Shelving should be stainless steel, slatted, 375mm deep, easily cleaned and allow air to circulate around stored packs. Freestanding or mobile shelving provides a practical solution for handling the flow of products in and out of storage and cleaning. It allows staff to access all sides of the storage area for rotation of sterile packs. Open shelving is more commonly used as it allows dust to pass through making them easier to clean than solid shelves.

Worktop furniture

Work benches for standing activities should have a worktop height of 900mm and be constructed of stainless steel. Furniture should be movable with height adaption facilities.

Hand-wash basins

Hand washing remains one of the most significant ways in which cross-infection through contact can be avoided. To enhance this, staff should be aware of its importance and hand-wash facilities should be available in appropriate places and be accessible.

The selected system for soap- and towel-dispensers is a hospital policy and dictates the type of dispenser to be specified.

Ultrasonic cleaners

Ultrasonic cleaners are mechanical pre cleaners and often used as an initial step in the process of cleaning surgical instruments. Ultrasonic cleaners are a mechanical system that uses sound waves along with water and detergent to remove soil from instruments. Both tabletop and floor units are available. Floor units are designed to accommodate large quantities of instruments at one time and can have either single or double chambers. Following the ultrasonic cleaning process, instruments are placed into washer/disinfectors. Instruments and trays are loaded into the unit on the decontamination side of the CSSD facility, and removed upon completion of the cycle on the clean side of the facility.

Photograph 23: Various types of automated washers and washer-disinfectors

Automated washers / Washer-disinfectors

Washer-disinfectors are used to clean and disinfect a range of devices and materials that are intended to be re-used. The cleaning and disinfection process is intended to make the items clean but also safe (microbiologically) for staff to handle (as a prerequisite for packaging and sterilisation), reducing the load of microorganisms on device surfaces and also often for direct/indirect use with a patient (in particular non- and semi-critical devices).

There are many different sizes and types of washers. They may be single or multi-chamber, single (one) or double (two) door, and varying in size/design. In single-door designs, the devices or materials (referred to as the ‘load’) are introduced and removed from the same door, while double-door designs allow for the introduction and removal through separate doors (pass-through design). The pass-through door washers are preferable, as contaminated items can be loaded in the ‘dirty’ area and removed in the ‘clean’. The disadvantage of a single-door washer is that the contaminated and clean items are loaded and unloaded through the same door from the ‘dirty’ side.

Sterilisers (autoclaves)

For maintenance purposes, the side, back, and top panels of free-standing sterilisers should be easily removable and replaceable.

Special foundations are not normally required. The weight of the steriliser, which can be as much as 2 000kg when fully loaded, should be borne by at least four pads, each measuring at least 150 x 150mm. Floor mountings should be designed to minimise vibration.

A steriliser installation will normally be separated into two areas: a plant room containing the steriliser itself, services and ancillary equipment; and an adjacent loading area from which the steriliser is loaded and unloaded. The areas are divided by a partition wall into which the front panel and door of the steriliser are set.

Maintenance staff should be able to enter the plant room without passing through the loading area. Direct access between the plant room and loading area should be provided for use during testing. Page Break

Electrical

Specialist electrical installations

Rapid development of technological innovations in all spheres of electronic devices demands up-to-date knowledge which cannot be captured in a design guide of this nature.

It is therefore imperative that all power be fully accommodated, and that the systems are designed to be responsive to specific equipment. The specific choice of equipment must be established early on to promote a consistent and coordinated plan.

Careful attention must be given to the location and capacity of electric outlets to ensure capacity and compatibility with the equipment to be installed.

Electrical points

Sufficient 13-amp outlets should be provided to supply all portable appliances. Designers should ensure that they have access to a complete schedule of the equipment that requires electrical supplies and a clear understanding of the operational policies regarding the use of all equipment.

Switched socket-outlets should be provided in corridors and in individual rooms to enable domestic cleaning appliances to operate over the whole facility.

Appliances requiring a three-phase supply or those rated in excess of 13-amp single phase should be permanently connected to separate fused sub-circuits. The sub-circuits should be fed from the distribution board and terminate at a local isolator. Designers should agree on the location, type (flush- or surface-mounted), form of indication, type of cable outlet, facilities for locking of isolator in the off position, and labelling of such isolators with the planning team.

Lighting

The layout of artificial lighting should be designed in a modular fashion to accommodate future changes, yet take into consideration current workspace layout.

Light fittings are potentially major sources of dust- and dead-insect build-up. Recessed and sealed fittings utilising recessed fluorescent luminaries with acrylic prismatic lenses would greatly contribute to overcome this problem. However, regular maintenance policies still need to be put in place by hospital management to maintain a clean environment.

It would be preferable to have pendants above workspaces in the IAP area. Examination lighting (examination lamps with foot-operated switches) is required in the IAP (equipment examination) areas.

Light switches with occupancy sensors should be considered to reduce energy consumption.

Emergency lighting is not considered to be essential.

HVAC

A well-designed HVAC system is a critical element in the design for infection control. Through constantspace airflows and differentiation in air pressures, contamination can be contained and clean environments can be maintained.

In order to achieve this it is imperative that 100% constant fresh air is provided to the CSSD through a dedicated air-handling unit complete with primary air heating, cooling, humidification, dehumidification, and filtration. The HVAC must be engineered with excellent energy efficiency through performance management. Refer to IUSS:GNS Building engineering services.

Air flow should be designed so that air flows out of clean areas into dirty areas via positive pressure. Positive air pressure is required in the "clean" areas of the unit to reduce air movements into these areas from the "dirty" areas of the unit, as per the diagram below.

Plant and Services

The various areas within the CSSD should accommodate the equipment manufacturer's recommendations, as space requirements may vary from one manufacturer to another. All items of equipment will need to be itemised and the dimensions of all equipment obtained from manufacturers to ensure they can be suitably housed.

The following requirements could be relevant to washer/disinfectors and sterilisers:

doors are to be sized to allow passage of equipment;
electricity loads need to be estimated and catered for;
weight loads need to be estimated and checked structurally;

equipment requiring services such as water and special power need to be accommodated at an early stage;
all sterilisers should be located to have service/maintenance access to equipment from outside the unit whenever possible;
space allowed for and around equipment should be sufficient to allow for the physical equipment as well as circulation/working space around the equipment;
the spaces should be able to reasonably accommodate access and positioning of possible outsize equipment, including point of delivery to point of positioning; and
the area should be designed to allow for periodic ease of routine cleaning or, particularly in dirty areas, for handling of accidental spillages.

In many cases decontamination is at least a two- or even three-step process to include cleaning and disinfection and/or sterilisation; however, cleaning alone or a multi-step process of cleaning, disinfection and sterilisation may also be required for decontamination depending on the final use of the surface/item.

Detergent:

A compound, or a mixture of compounds, intended to assist cleaning. Detergents are a sub-class of surface active agents (‘surfactants’). Also commonly referred to as cleaners or cleaning chemistries, but detergents are only one part of these mixtures.

Device:

Any instrument, apparatus, appliance, material or other article intended to be used for the purpose of diagnosis, prevention, monitoring, treatment or alleviation of disease or other medical/surgical use. A reusable device is designed to be used many times on different patients, being provided with detailed instructions on how it can be safely reprocessed between each patient. A single-use device (SUD) has been designed by a manufacturer to be used on a single patient only and then discarded. The terms ‘device’ and ‘instrument’ are used interchangeably throughout the book.

Disinfectant:

A physical or chemical product for disinfection.

Disinfection:

The antimicrobial reduction of the number of viable microorganisms on a product or surface to a level previously specified as appropriate for its intended further handling or use. There are various levels of disinfection, based on their ability to kill certain types of microorganisms.

Facility:

A complex of buildings, structures, roads and associated equipment, such as a Hospital or Health Care Facility that represents a single management unit for financial, operational maintenance or other purposes.

Fixtures:

Items that are permanently fixed to the building or permanently connected to a service distribution system. These items require service connection (e.g. electrical, hydraulic, mechanical) and includes basins, light fittings, clocks, medical service panels, etc.

Fittings:

Refers to fixed items attached to walls, floors or ceilings that do not require service connections such as, hooks, mirrors, blinds, joinery, pinning and writing boards.

Fumigation:

The delivery of a disinfectant to an area by aerial dispersion, usually in the form of a gas, vapour or aerosol.

Fungi:

A group of cell wall containing eukaryotic microorganisms, that can be further sub-divided into moulds (or filamentous fungi, as they can form long filaments or lines of cells) and yeast (unicellular, single-celled forms).

Gross area:

Gross area includes, in addition to the net area, partitions and circulation internal to the functional area of the department.

Guideline:

Document used to communicate recommended procedures, processes, or usage of particular practices.

Infection:

The detrimental introduction and colonisation of a host (human/animal) by a microorganism.

Infection prevention/control:

Discipline concerned with preventing the spread of infection. Often used interchangeably, ‘prevention’ is more correctly used to describe practices to prevent infection while ‘control’ may also include practices to control the infection after it has taken place (e.g., isolation precautions, antibiotic or other drug-based therapy etc).

Label:

An identification indication on a product or other article. This can include the manufacturer, their address, product/item identification (e.g., serial or part number), instructions for use etc. A product label can include what is physically written on the product (the attached label) but also any other accessory information such as additional instructions for use, the material safety data sheets (MSDS) and technical literature.

Load:

Collectively, all the goods, equipment and materials that are put into a steriliser or washer/disinfector at any one time for the purpose of processing it.

Medical device:

Any instrument, apparatus, appliance, material or other article.

Mobile equipment:

Equipment items (medical or non-medical) that require electrical or mechanical connections or floor space.

Net area:

Net area is the actual floor area in a room or functional area (finish to finish) that can be used by people, furnishings, or equipment.

PPE (Personal Protective Equipment):

Specialised clothing or equipment worn by an employee for protection against a hazard.

Pressure:

The effect that occurs when a force is applied on a surface or the force applied per unit area. For example, atmospheric pressure is the pressure exerted by the earth’s atmosphere and which at sea level is known to be ~101.3kPa (=14.7 lb in^-2, 1 bar, 760 mmHg or 760 Torr).

Process:

A designed sequence of operations or events, possibly taking up time, space, expertise or other resource, which produces some outcome.

Safety:

The condition of being protected from danger, harm or injury.

Soil:

See contamination.

Sterile:

Free from viable organisms.

Sterile barrier system :

Package that provides a barrier to microorganisms and allows aseptic presentation of product at the point of use.

Sterilisation:

Defined process used to render a surface or product free from viable organisms, including bacterial spores.

Tray:

A container, usually with a flat base and upturned edges, used for containing an assembly of surgical instruments for packing to be used in an aseptic procedure.

Validation:

Documented procedure for obtaining, recording and interpreting the results required to establish that a process will consistently yield product complying with predetermined specifications.

Virus:

A class of microorganisms that are unable to grow or reproduce outside a host cell.

Washer-disinfector:

A machine that cleans and disinfects medical devices and other articles used in the context of medical, dental and pharmaceutical practice.

 Decontamination involves the use of automated and manual cleaning to remove harmful blood-borne pathogens on the surfaces of equipment and instruments. Soiled items for re-use (medical devices, textiles and equipment) are received in the sterilising department after use in the various clinical departments. These could be operating theatres, emergency department and various wards. Medical devices, equipment and other contaminated articles will be sorted, disassembled, pre-rinsed and cleaned in the decontamination/dirty area. Used linen is put into linen bags and sent to the laundry. Waste items are sorted into suitable containers, according to policy, for appropriate disposal methods.
-If items are heavily soiled a manual washing procedure will precede the automated cleaning process by washer-disinfectors. For manual cleaning, a double- (two-) sink arrangement is optimal, one for cleaning and one for rinsing. Automated washers or washer-disinfectors can be provided as single or double-door designs (the latter to allow for physical separation of the dirty and clean areas of the decontamination area).

 If the generic plan used as basis for this study (LAYOUT 2.1) is subjected to an area analysis, the following table can be compiled (TABLE 4.5) for an autonomous (support services not shared) CSSD of 600m². If staff facilities and corridors are shared with another department (e.g. theatre department), the CSSD’s size reduces to 450m² as per TABLE 4.6, illustrating the difficulty in achieving universally applicable areas, and the effect of hospital-specific policies.

 Due to the uni-directional sequential nature of the work flow in the CSSD, activities are interrelated and inter-dependent. It is, therefore, critical to the functional efficiency and safety of the CSSD that those areas are sequentially linked for uni-directional flow-through of instrumentation, with no room for back tracking.
-The above work flow and interrelationship between the adjacent areas dictates the characteristics of each space. In order to discuss each area individually, it is necessary to have a base plan as a reference point. The typical floor layout based on a 600m<sup>2</sup> unit will be used for this purpose.

 ==Definition of terms==
-Adventitious contamination
+Adventitious contamination:
 The accidental introduction of environmental micro-organisms onto a medical device or product.
-Anatomy
+Anatomy:
 The study of the structure of living things.
-Antimicrobial
+Antimicrobial:
 The ability of a process or product to be effective against microorganisms by either killing them or inhibiting their growth.
-Antisepsis
+Antisepsis:
 Destruction or inhibition of microorganisms in or on living tissue, e.g. the skin, mucous membranes or wounds.
-Antiseptic
+Antiseptic:
 An antimicrobial product or process used on the skin or other living tissues. In some countries antiseptics are labelled as disinfectants or antiseptic disinfectants.
-Asepsis/Aseptic
+Asepsis/Aseptic:
 Free of, or using methods to keep free of, microorganisms.
-Bacteria
+Bacteria:
 Also known as eubacteria. A group of unicellular, prokaryotic microorganisms. Examples include Bacillus, Staphylococcus and Pseudomonas.
-Biocide
+Biocide:
 A general term referring to any chemical or physical antimicrobial agent that inhibits or inactivates life. The term ‘micro-biocide’ are those biocides that are effective against microorganisms. Chemical biocides include chlorine, iodine, alcohols and hydrogen peroxide. Physical biocides include heat and radiation.
-Biofilm
+Biofilm:
 Communities of microorganisms (either singular or multiple species) developed on or associated with surfaces.
-Carrier
+Carrier:
 A device that carries, conveys or transports the load through the department via a trolley/carriage or on a rail/track into/through a decontamination process.
-Cleaning chemistry
+Cleaning chemistry:
 A formulation (or mixture of chemicals) designed for cleaning purposes. Cleaning chemistries are often referred to as ‘detergents’, but detergents are usually only one part of these mixtures that can include biocides, enzymes, buffers, chelating agents and other components.
-Circulation
+Circulation:
 Circulation space is the space required within a department or unit to enable movement and functionality between individual rooms/ spaces.
-Cleaning
+Cleaning:
 The removal of contamination (often referred to as ‘soil’) from a surface to the extent necessary for further processing (e.g., disinfection, sterilisation) or for intended use.
-Contamination
+Contamination:
 The presence of dirt or ‘soil’ that can include various materials, chemistries and bio burden (such as microorganisms). Depending on the situation, contamination may be visible (e.g., a blood spill) or invisible (e.g., the presence of microorganisms). Contamination of a device (e.g., an endoscope) following patient use is generally referred to as ‘soil’.
-Decontamination
+Decontamination:
 Physical and/or chemical means to render a surface or item safe for handling, use or disposal. In many cases decontamination is at least a two- or even three-step process to include cleaning and disinfection and/or sterilisation; however, cleaning alone or a multi-step process of cleaning, disinfection and sterilisation may also be required for decontamination depending on the final use of the surface/item.
-Detergent
+Detergent:
 A compound, or a mixture of compounds, intended to assist cleaning. Detergents are a sub-class of surface active agents (‘surfactants’). Also commonly referred to as cleaners or cleaning chemistries, but detergents are only one part of these mixtures.
