Porter can supply goods to a reception without entering clean area One way workflow When linen is inspected, folded and packed in a CSSD, a separate room should be dedicated for that purpose, to avoid spread of lint. Linen packing table can be used by 2 persons, working together standing on each side. TYPICAL CSSD DESIGN Clean supply/linen goods flow 08/19/11  I Anuradha Desai I Getinge Academy I Public Basic Design of CSSD

Solutions for the Linen room Example – calculated demand of 3.2 people in the Linen packing area, make space for totally 4 persons Drawing shows minimal recommended dimensions to fulfill the work tasks in the linen inspection, folding and packing area. The linen trolley can accommodate approx 1000 liters of linen. This corresponds to 33 baskets, when later packed into baskets. If space is limited – consider inspection, folding and packing at the laundry and only pre-storage, assembly, labeling and sterilization at the CSSD. TYPICAL CSSD DESIGN 08/19/11  I Anuradha Desai I Getinge Academy I Public Basic Design of CSSD

Changing rooms Local requirements should be followed. Different ways to arrange Changing rooms to achieve different outer dimensions of the total changing area. TYPICAL CSSD DESIGN 08/19/11  I Anuradha Desai I Getinge Academy I Public Basic Design of CSSD

A minimum distance of 1500mm between packing tables and minimum 900mm, side facing against a wall, as a good recommendation. TYPICAL CSSD DESIGN Control & packing area - 1 Packing table located sideways from window avoiding light reflexes on instruments and work surface. 08/19/11  I Anuradha Desai I Getinge Academy I Public Basic Design of CSSD

By the inspection of the cleaning result, functional test and packing, height adjustable tables can be used for optimal ergonomic work conditions. Loading trolleys can also be designed as height adjustable units, to support and ease work conditions CAD illustration TYPICAL CSSD DESIGN Control & packing area - 2 08/19/11  I Anuradha Desai I Getinge Academy I Public Basic Design of CSSD

Air lock with a recommended minimum 1400mm width and including hand washbasin. Air lock can also be used as service area at narrow installations. Return transfer hatch for racks - if, as in this design, used by loading of sterilizers. TYPICAL CSSD DESIGN Sterilizer area 08/19/11  I Anuradha Desai I Getinge Academy I Public Basic Design of CSSD

Mobile or stationary storage for sterile goods in baskets and/or containers. An over-pressure shall be kept in sterile store – creating an airflow from sterile store to the surrounding areas. TYPICAL CSSD DESIGN Sterile store - 1 08/19/11  I Anuradha Desai I Getinge Academy I Public Basic Design of CSSD

Open storage units, allowing good ventilation of stored goods as well as a good overview of the content. Inspection and recording of sterilized goods to have a tracing function! Assembly of goods according to received orders from user. CAD illustration TYPICAL CSSD DESIGN Sterile store - 2 08/19/11  I Anuradha Desai I Getinge Academy I Public Basic Design of CSSD

Sterile store - 3 Position Baskets racks so that the baskets easily can be pulled out. Try to achieve corridors width min 1200mm between Basket racks and/or Wire shelf. If space is limited, there are questions to be raised: Will goods be sent out directly to the users? Can goods be stored at the users site? Sterile store capacity, according to demand of individual sites. Lockable Pass-through cabinets available for pickup of goods when CSSD is closed.

INFECTION CONTROL TRENDS & DEVELOPMENTS 08/19/11  I Anuradha Desai I Getinge Academy I Public NEW TRENDS AND DEVELOPMENTS!

Trends and Development Basic design concept for the CSSD/TSSU Controlled room ventilation (air flow) to get good production conditions: - Soiled zone – negative pressure (-) versus adjoining areas - Clean zone – positive pressure (++) versus to all adjoining areas - Sterile zone – positive pressure (+) New demands: 08/19/11  I Anuradha Desai I Getinge Academy I Public - Soiled zone – negative pressure (-) versus adjoining areas - Clean zone – positive pressure (++) versus to all adjoining areas - Sterile zone – positive pressure (+) (-) (++) (+)

Goods carriers Increased usage of solid instrument containers, used as goods carrier for the surgical trays Background - Increased physical protection of the surgical instruments - Paper wrapping may break 08/19/11  I Anuradha Desai I Getinge Academy I Public Consequences Increased washer-disinfector capacity needed (compared to nested empty baskets) Mixed usage occurs – ISO/SPRI/DIN baskets and containers, others? Increased demand on the internal logistic (as T-Doc) within the CSSD. –As if the lid and bottom of the container is one unit that shall be matched together after washer-disinfectors or washer-disinfector / cart washer. (Increased number of work procedures!) More heavy goods carrier (empty container +50% weight compared to empty basket) - Increases the demand of lifting devices - Heavy load program  extends the processing time of the sterilizers

Washer-Disinfectors Transition from house steam supply to electrically heated equipment Background: - Big investment and maintenance costs. - Energy loss during steam transport. Transition from external drying to washer-disinfectors with integrated drying. ( An interpretation of SS-EN ISO 15883) ” Air-tight” installation by pass-through installations . Non-vented units (No conn. to ventilation) 08/19/11  I Anuradha Desai I Getinge Academy I Public Consequences Electrically heated washer-disinfectors  longer processing time than steam heated units More washer-disinfectors required at the CSSD - Increased number of washer-disinfectors  possible automation demand Integrated drying extends the processing time More washer-disinfectors required at the CSSD - Increased number of washer-disinfectors  possible automation demand Equipment and installation practise have to be designed to reduce air flow and vent.

Linen reprocessing Reduced usage of reusable sterilized dressing sets for surgeon, patient and equipment. Background - Disposable dressing sets used instead (sometimes cheaper) 08/19/11  I Anuradha Desai I Getinge Academy I Public Consequences Existing CSSD’s planned for reprocessing of reusable linen have spare capacity in their sterilizer barrier Area for linen handling can be reduced and used for other purpose Note! Very important parameter since linen normally stands for 30-40% of total sterilization goods volume Linen usage

Sterilizers Reduced processing time Automation increase ” Air-tight” installation by pass-through installations Service access from unloading side by pass-through installations Sound level reduction Increased water and energy consumption awareness (”Green”) 08/19/11  I Anuradha Desai I Getinge Academy I Public Consequences Number of units required will be less, due to increased efficiency. However, bigger units not always best selection! Installation might require more space totally as fixed or moving automated units are attached to sterilizer. Equipment and installation practise have to be designed to reduce air flow Separated vacuumpumps - on site adapted equipment. Adaptation of automation units and options to actual conditions to be observed – increase awareness.

The processing environment Improved working environment within CSSD The CSSD work getting a higher “status” ” Green concept” Background - Avoid working injury. Sick leave costs money. - Computerized workplace, focus on close connection to surgical department. 08/19/11  I Anuradha Desai I Getinge Academy I Public Consequences Sound-absorbing actions implemented at: - washer-disinfector installations - sterilizer installations (separate located vacuum pump) Focus on equipment with better ergonomics: Height adjustable tables and trolleys, side mounted operator panels with at more convenient operator height. Quote from Handbook for Health and nursing care (Sweden): ” Avoid to carry and lift. Try instead to move by pushing or pulling and reduce the friction by means of assistance” Less energy, water consumption required.

Centralization (”Super CSSD’s”) Outsourced processing by a Super CSSD provides ”factory like” sterile services outside hospitals (UK, NL, FR, Singapore) Background - Low utilization of existing plants. - Big investments required on existing plants to be accredited according to quality standard in accordance with medical devices directive 93/42/EEC - Reduce cost per produced unit 08/19/11  I Anuradha Desai I Getinge Academy I Public Consequences Large scaled CSSD’s as base, but adapted for “fast track” performance Longer opening hours, (7days/24h) Increased number of instruments needed  higher investment for instruments? Optimize the goods flow from and to end users Short circulation time (Penalty fee if delivery delay) Transports considered as dangerous goods  special demands on performance Automation may be required. Smaller chamber units? in standby mode for fast track needed.

Reprocessing time Speed-up reprocessing time including the return and distribution transports. Background - Since outsourcing companies normally do not own the instruments, the high investment made by hospitals in surgical instruments do request a short turn-around time. - Reduced budgets put pressure on supply departments, also at hospitals, for increased efficiency. 08/19/11  I Anuradha Desai I Getinge Academy I Public Consequences Disinfection and sterilization processing time have to be reduced. Inspection and packaging process have to be more efficient. Queue of goods before Washer-disinfectors and Sterilizers as well as before Inspection and Packaging have to be heavely reduced. Logistic assistance must be implemented. REDUCE TIME!

Reprocessing cost Bring investment, running cost and processing area down on reprocessing equipment. Reduce staff Separate purchase of reprocessing equipment to get optimal benefits? 08/19/11  I Anuradha Desai I Getinge Academy I Public Consequences Need for an efficient work flow. Increased use of standardised work routines More productive equipment. Supply of ”superior total package” – ”All” what is required?

Optimize Adaptation of an optimal work flow to each customer requirements . Production area reduction 08/19/11  I Anuradha Desai I Getinge Academy I Public Consequences An initial detailed site condition examination. A more accurate equipment design and evaluation, Peak Demands to be addressed. Requirement of compact interior design proposal and the installed equipment.
