3 Procedure for Performing Heel Prick for Newborn Blood Spot Screening Introduction Newborn screening aims to identify babies who are at high risk of having certain serious but rare conditions before they develop symptoms. Screening is not the same as diagnosis; instead it identifies which babies need to go on to have diagnostic tests to determine whether or not they do have the condition. By detecting these conditions early it is possible to treat them and reduce their severity. Newborn blood spot screening is a crucial part of the national child public health programme and is offered to all babies in the United Kingdom. Five conditions are screened for in the Northwest region which are Congenital Hypothyroidism (CHT), Phenylketonuria (PKU), Sickle cell disorders, Cystic Fibrosis (CF) and Medium Chain Acyl-CoA Dehydrogenase Deficiency (MCADD) The blood spot sample should ideally be taken on day 5 by the midwife, and certainly between day 5 and 8 for all babies regardless of milk feeding and prematurity.

6 PROCEDURE ACTION Complete all boxes on the card and apply baby s barcode label (when available). If label is unavailable the NHS number should be handwritten on the card. When completing the card care must be taken to avoid contamination through placing the card on a dirty surface of through touch Verbally confirm baby s full name, date of birth and parents contact details Verbally confirm parental informed consent to procedure and document in records Recommend comfort measures for the baby. Feeding, sucking and engaging the baby through face-to-face contact, voice and touch, is beneficial. Ensure that the baby is cuddled and in a secure position for taking the sample. The blood sample should be taken from a clean heel. If skin is not meticulously clean it should be washed with plain water or alcohol swab. REASONING To ensure correct details and to enable sample / results to be tracked. To avoid contaminating the blood spot sample To ensure you have the correct label/information recorded on the card Comply with NHS Wirral Consent Policy To comfort the baby. To make it easier for the baby to regain his/her calm and comply with the procedure. To prevent contamination of the sample that can affect the results of the test. Decontaminate hands and apply gloves Screening Link Health Visitor will apply yellow soft paraffin to the heel before carrying out the test using a newborn automated device. Depth of incision to be less than or equal to 2.0 mm. Safely dispose of all equipment Decontaminate hands Document in records Universal precaution of taking blood to prevent spread of micro-organisms To reduce pain, bruising and obtain the sample more quickly. To reduce the risk of accidental injury from manual lancets. Manual lancets are not recommended as there is no control on depth of incision. Health and safety of staff and clients To prevent spread of micro-organisms NHS Wirral Record Keeping Policy 6 /15

7 ACTION Allow foot to hang down to increase blood flow. Heel puncture should be performed on the plantar surface of the heel, beyond the lateral and medial limits of the calcaneous, marked by the shaded areas in the diagram. Avoid posterior curvature of the heel. Before activation place automated device firmly against the heel. REASONING To minimize the risk of calcaneal puncture that may lead to calcaneal osteomyelitis (inflammation of the heel bone). The heel puncture should only be taken from the shaded areas indicated by the arrows. Circle filled and Layering Insufficient Evenly saturated multiple applications ACTION REASONING The aim is to fill the circles on the newborn blood spot card completely. Wait up to 15 seconds to allow blood to flow. The laboratory punches out several circles of the blood spot for analysis. The sample needs to be sufficient to screen for all of the conditions and to be retained if retesting is required to check equivocal or positive results. Apply the blood drop to one side of the card. Allow the blood to fill the circle by natural flow, and seep through to the back of the card. Fill the circle completely and avoid layering blood. Dispose of automated device in sharps bin Layering of the blood is unacceptable for testing (see diagram above) because too much blood can cause erroneous results To ensure safe disposal of lancet as per infection control policy, sharps usage and disposal 7 /15 To prevent excessive bleeding and bruising

8 Wipe excess blood from the heel and apply gentle pressure to the wound with cotton wool ball. and to protect the wound. If the blood flow ceases: The congealed blood should be wiped away firmly with cotton wool or gauze. Gently massage the foot, avoid squeezing, and drop the blood onto the card. To disturb the clot and encourage blood flow. Reduce the amount of pain and bruising caused by the procedure. If the baby is not bleeding a second prick is necessary: The second prick should be taken from a different part of the same foot (within the area indicated above) or the other foot. Apply cotton wool and secure with micropore, or spot plaster if required. Remove gloves and dispose in accordance with infection control policy, clinical waste The original site is avoided to prevent sample containing excessive tissue fluid and reduce pain. To avoid soiling linen. To prevent cross infection. 8 /15

9 After taking the blood sample It is important that the laboratory receives the blood sample promptly to ensure that babies with the conditions are seen quickly. Parents also need to know when to expect the results. This will help reduce their concerns about the results, as well as providing an additional safety net in following up missing results. ACTION If a parent does not wish to be contacted about future research about newborn blood spot screening, the health professional collecting the blood sample should mark NO RESEARCH CONTACT on the blood spot card Allow blood spots to air-dry before placing in the glassine envelope The glassine envelope should be placed in an envelope with pre-printed address stickers inserted on and be posted with a first class stamp within 12 hours of taking the sample The professional taking and posting the sample should record the sample date and posting/dispatch date Record taking the test in the Personal Child Health Records and fax the Health Visitor Neonatal Screening Information Form to the family Health Visitor and General Practitioner, followed by the hard copy being sent to the Family Health Visitor complying with Nursing and Midwifery Council and NHS Wirral record keeping guidelines Inform parents how and when they will receive results REASONING In accordance with the Code of Practice for the storage and use of residual blood spots.
