what should all staff be trained on in relation to infection control

how infections are transmitted
how to prevent transmission of infections
what to do in the event of an accident or personal injury
your practice policy on infection control

what should members of staff involved in the decontamination process be trained on

preparing for decontamination
understanding key principles
able to use all cleaning methods
know what kind of sterilisers and what they are used for
understand handpiece lubrication, inspection and wrapping
know how to store instruments after sterilisation
understand record management
understand importance of reporting failures

what is guidance

recommendations for the care of individuals by healthcare professionals based on best available evidence

what is standards

provides guidelines or characteristics for activities and their results aimed at the achievement of the optimum degree of order in a given context

what is legislation

process of enacting statutory laws

what are the key points to consider when purchasing equipment and instruments

undertake review of available decontamination capabilities ensure that all re-usable medical devices are being purchased can be decontaminated review of device manufacturers instructions for reusable devices UKCA mark

what is the procurement contract for Scotland

NP 143

when should manual washing be done

when required by manufacturer's instructions automated cleaning processes not available

what types of records of the cleaning process are required

process records verifiable against skills register/training documents batch records kept indicating who was responsible for cleaning the devices

what are the key elements of the cleaning cycle (sinner circle)

time temperature chemicals energy

what does the documentation of the washer disinfector include

loading procedure choice of operating cycle choice of detergent trained staff record details of items processed

what are the 5 stages of the WD

flush wash rinse thermal disinfection drying

what does steam sterilisation depend on

contact between the steam and all surfaces of the load so all items must be clean and dry before this

what should the sterile product release procedure include and where should it be documented

maintenance and test records are up to date and satisfactory sterilisers automatic controller is indicating a satisfactory cycle temperature and pressure record for cycle shows attainment of required conditions the load was correct for that type of steriliser package is intact and not wet documented in the steriliser batch records

what is parametric release

release of a batch of sterilised items based on data from the sterilisation process

what are the key points of documentation procedure for the steriliser

type of load loading procedure choice of operating cycle sterile product release procedure trained staff record details of items processed drain water reservoir and chamber daily

what are the daily tests for the WD

check cycle used time detergent levels spray arm rotation spray nozzles for blockage remove and clean strainers and filters

what are the weekly tests for the WD

perform safety checks carry out daily tests perform cleaning efficacy tests by residual soil detection

what are the quarterly and annual checks for the WD

validation, verification and maintenance by the CPD

what are the daily checks of the sterilisers

check time temperature pressure indicated steam penetration test (both test device and indicator specified by steriliser manufacturer)

what are the weekly checks of the sterilisers

examine door seal for signs of deterioration or leaks check security and performance of door safety devices ACT and steam penetration air leakage test air detection system function test

what insurance must you have for the steam steriliser and what regulations state this

must have pressure vessel insurance for each steriliser stated by pressure systems safety regulations

what is the general management of the LDU

defined and documented responsibility for managing decontamination of dental instruments within the practice (usually the GDP)

what is risk management of the LDU

all risks associated with decontamination premises, equipment and services are identified, assessed and managed must be comprehensive, written, decontamination policy with clear reference to risk management to cover services, equipment, processes and premises involved in decontamination

what is the quality management system of the LDU

policies and procedures to control the decontamination process

what can the management requirements for an LDU be divided into

general management risk management health and safety training quality management systems

what are the 8 quality management principles

customer focus leadership involvement of people process approach systems approach to management continual improvement factual approach to decision making mutually beneficial supplier relationships

what is an LDU characterised by

sterilises only single wrapped or unwrapped items processed items are not transferred offsite under the control of one or more clinicians who use the re-processed devices does not supply a third party

what should the design layout of the LDU be compliant with

the SHPN 13 part 2

what are the common requirements for all decontamination areas

changing areas and washing facilities should be at lowest end of any air pressure gradient interior should be designed to avoid dust traps and to permit ease of cleaning junctions between walls, floors and ceilings should be covered where possible
