4 1. Aim To ensure the correct blood sample is taken from the right patient in a safe, correct manner first time To minimise the risk of introducing harmful micro-organisms into the blood stream 2. Objective This policy is to ensure all clinical staff (including medical staff) that are responsible for venous blood sampling within NHS Forth Valley are fully aware of the policy content and control measures required to perform the procedure correctly, and to minimise infection and risk of harm to the patient. 3. Responsibility a All clinical staff: i) must adhere to the policy ii) are responsible for minimising the potential of cross infection iii) are responsible for maintaining their competency in venepuncture b Venepuncture Assessors: i) must be experienced and competent in venepuncture ii) iii) iv) must be able to offer help and support to learners and practitioners performing venepuncture must act as a role model and actively promote good practice within their clinical area must peer assess other staff members within their own clinical area annually using the assessment criteria provided by Practice Development Unit v) must keep records of these assessments at ward level for audit purposes vi) vii) viii) must challenge inappropriate practice must ensure a copy of signed competency sheet is sent to Practice Development Unit for entry into database must attend an assessors update day, at least every 3 years, to ensure their knowledge is up-to-date Version st August 2015 Page 4 of 14

5 c Managers: i) are responsible for ensuring that clinical staff are aware of this policy and that it is adhered to d Practice Development Unit: i) are responsible for delivering initial evidence based venepuncture training, either face to face training or via e-learning module ii) iii) iv) will supply all clinical staff at training session with a competency sheet to complete following theory session and advise staff how to achieve competency will fast-track and familiarise new clinical staff with Forth Valley guidelines who have completed training and competency within another Health Board will annually invite venepuncture assessors to attend an update session v) must keep the policy up to date vi) vii) will audit compliance with the policy will hold a database of all current venepuncture assessors 4. Background Venepuncture or phlebotomy is the term used to describe the insertion of a needle into a vein to withdraw blood, for haematological, biochemical or bacteriological analysis. Venepuncture is a practical skill that can be performed by a range of health care professionals. It is the most common invasive procedure undertaken in healthcare. 5. Education and Training Only clinical practitioners who have received appropriate training and supervision will undertake venepuncture Following training, a period of supervised practice with a final competency assessment will be undertaken There is an expectancy that competency will be achieved within 6 months of initial theory training if this is not achieved further discussion with Practice Development will be required The individual practitioner and the Practice Development Unit will keep written records of competency Ward based nominated venepuncture assessors and Practice Development Unit staff can assess competence Annual update and re-assessment will occur for all clinical staff to ensure competency is maintained All clinical staff undertaking venepuncture are responsible for ensuring that their practice will promote and protect the interests and dignity of the patients Version st August 2015 Page 5 of 14

6 Detailed information regarding the venepuncture procedure can be found in the LearnPro e-learning module 6. Risk Management To manage the risk, it is advisable that a risk assessment is carried out to identify why staff are unable to obtain blood using the safest method of blood collection, for example, very small or difficult veins, and also to ensure control measures are in place to make blood collection as safe as it can be, for example, using the Blood Transfer Device. 7. Infection Control In order to reduce the risk of cross infection, standard infection control precautions must be adhered to at all times. In particular: Sharps management i. A safety device must be used to prevent needlestick injury ii. sharps must be disposed of immediately after use in a sharps bin Hand hygiene i. level 2 handwash must be performed prior to undertaking the procedure ii. the use of gloves does not negate the need for hand hygiene iii. hands must be decontaminated after removing gloves and apron Personal Protective Equipment (PPE) apron and gloves must be worn during the procedure Skin must be cleaned using an antiseptic containing 70% isopropyl alcohol and allowed to air dry for thirty seconds before venepuncture. After cleaning the skin, the insertion site must not be re-palpated. If under certain circumstances this is not possible then sterile gloves must be worn 8. Prior to Procedure The request form must be completed before the blood sample is taken Informed consent must be obtained prior to the procedure. If consent directly from the patient is not possible then it must be obtained as per Adults with Incapacity (Scotland ) Act 2000 The correct identification of the patient must be confirmed prior to the procedure: o The patient must be asked to positively identify him or herself by giving their full name (first and last name) and date of birth prior to being bled o Identity must not be assumed even for familiar patients who are regular attenders or long-standing in-patients o This must be checked against the details on the request form and, for inpatients, what is on the patient identification band o All inpatients must wear a patient identification band (with exception to Mental Health, Learning Disabilities and Older People Services) Version st August 2015 Page 6 of 14

7 o The full name and date of birth stated by the patient must EXACTLY MATCH the information on the patient s identification band and the information on the request form if there is any doubt, the patient should be asked to spell out their name to the requestor The person taking the sample must be satisfied that the identity of the patient matches the information on the request form, and the sample, and (for in-patients) the patient identification band BEFORE signing the request form and sending it to the laboratory If a patient is unconscious or unable to positively identify him/herself for other reasons (ie, confusion, neonates and small children), then identity must be confirmed by rigorous inspection of the patient s identification band. Verification of the patients identification should be obtained from a carer, if present at the patients beside and checked against the patient identification band Patients whose identity is unknown: If a patient is admitted unconscious and their identity is unknown, the following procedure must be followed: o The patient must be allocated a unique identification number o The minimum identifying dataset must include this number plus the gender of the patient (ie, Unknown Male A123456) o An identification wristband including this minimum data must be attached to the patient o This dataset must be used on samples and request forms until additional identification details become available o When additional identification details become available, the laboratory must be informed o The use of such temporary identification numbers increased the risk of confusion and errors in patient identification and should only be used when absolutely necessary 9. Order Communications (Order Comms) Samples NHS Forth Valley are in the process of transferring blood sample requesting from paper to electronic. Tests are requested as per the Order Comms Instructions within the DatrOCM Order Communications Application. When using this system the following is required when labelling the blood bottles prior to sending them to the laboratory: Labels are placed length ways on the sample bottle. Place label away from ends - do not allow ends to be covered. Label needs to be smooth and clear for the scanner. Please make sure the colour of the bottle matches the colour printed on the label. Always check the patient s information printed on the label (Name, DOB, CHI) is correct. Version st August 2015 Page 7 of 14

8 10. Venepuncture Sites Suitable veins for venepuncture are: - antecubital veins - cephalic or basilic veins on the forearm - metacarpal veins on the dorsum of the hand Unless justified by senior medical staff venepuncture must not be performed on patients: - following breast surgery on the arm of the same side as surgery - undergoing haemodialysis on the arm where their fistula is present - lower limbs (except in children) Venepuncture must not be attempted more than twice. It must be passed to a more experienced practitioner Venepuncture must not be performed using a vein proximal to an infusion site 11. Equipment When choosing the device to use for the procedure, consider the following: - are blood cultures required first? - 21g (green) needle for normal use - 22g (black) for more difficult access - butterfly is used for small and difficult vein sampling in adults and always in younger children and babies In normal circumstances in adults, blood collection must only be obtained by using the components of the Vacutainer system as this allows blood to flow directly from vessel to bottle In paediatric and adult patients with difficult access a butterfly/needle and syringe may be used, however, a Vacutainer Blood Transfer Device must be used to safely transfer the blood from syringe to bottles Safety devices must be activated either, after removal from vein and disposed of in sharps bin straight away All equipment is disposable/single use only and must be disposed of as clinical waste A disposable single use tourniquet must be used to prevent cross infection. If this is not possible a rubber wipeable tourniquet can be used. This must be thoroughly cleaned between patient use. 12. Blood Transfusion Samples An error when labelling a blood transfusion sample could result in an incorrect blood component being transfused to a patient, with potentially very serious consequences. The Hospital Transfusion Laboratory (HTL) operates a zero tolerance approach to sample labelling and those taking blood samples for Group & Save or Cross-Match purposes must take extra care to ensure they identify the patient correctly and label the samples accurately: The procedure outlined in section 7 must be strictly followed Version st August 2015 Page 8 of 14

9 The sample bottle must be labelled by hand at the bedside immediately after the sample has been drawn The sample must be labelled with the minimum transfusion dataset: o Forename and surname, o CHI number (or ED or major incident number if CHI not available) o Date of birth o Gender of the patient This dataset must precisely match that on the request form (an addressograph label is permissible on the request form, but care must be taken to ensure it is for the right patient If the identity of the patient is unknown, then the minimum dataset is unknown male/female and a unique identifier (ED or major incident number) This procedure is described in greater detail in the NHS Forth Valley Transfusion Protocol. 13. Blood Culture Samples Contaminated blood cultures are time wasting for the lab and potentially misleading for the clinician therefore correct equipment must be used. The use of a standard syringe and needle to inoculate blood culture bottles carries a high risk of contamination and needlestick injury therefore must not be done. Dedicated blood culture equipment is available for use Contamination is significantly reduced if the following 5 instructions are followed when taking blood cultures: o Tops of blood culture bottles must be cleaned with an antiseptic containing 2% chlorhexidine gluconate & 70% isopropyl alcohol and allow to air dry o Hand hygiene must be performed and PPE must be worn o Skin must be thoroughly disinfected with an antiseptic containing 2% chlorhexidine gluconate & 70% isopropyl alcohol for 30 seconds and allowed to fully air dry. After cleaning the site must not be re-palpated. o Procedure must be performed using strict aseptic non-touch technique o Blood cultures must always be taken first, before other blood samples Non-sterile gloves can be worn as long as care is taken to avoid touching the venepuncture site after skin preparation. If this is not possible then sterile gloves must be worn (compulsory for neonates) Blood culture procedure must be performed as per national guidelines DOH (2010) 14. After Procedure Samples must be taken in correct order of draw (see appendix 1) Samples must be mixed immediately following collection (see appendix 1) Large addressograph labels on the specimen bottle will NOT be accepted by the laboratory Version st August 2015 Page 9 of 14

10 The specimen must be labelled at the bedside AFTER blood is drawn into the sample bottle NEVER pre-label sample bottles The procedure must be fully completed BEFORE moving on to take blood from another patient High risk samples and request form must be labelled accordingly Samples must be transported to lab as soon as possible after procedure Bibliography Department of Health (2010) Taking Blood Cultures A Summary of Best Practice Available at: 03/Document_Blood_culture_FINAL_ pdf Lavery I, Ingram P (2005) Venepuncture: Best Practice, Nursing Standard, Vol. 19, No. 49, pp NHS Forth Valley (2014) Blood Transfusion Protocol Available at: documents/qi/ce_guideline_transfusionpolicies/transfusion-protocol.pdf NHS Forth Valley (2013) Blood & Body Fluids COSHH Generic Risk Assessment.
