244 responses A Questionnaire on the Prevention of Wrong-sided Nerve Blocks in the North Western Deanery Lie J 1 & Naylor K 2 1 Specialty Trainee (ST6), 2 Consultant Anaesthetist Insert your Logos/QR Code here BACKGROUND The number of peripheral nerve blocks being performed each year is at an all time high, leading to an increase in wrong-sided nerve blocks In 2009 the National Patient Safety Agency (NPSA) published data showing that wrong sided nerve block is commoner than wrong sided surgery In the UK 67 wrong site blocks were reported by the Safe Anaesthesia Liaison Group (SALG) & NPSA in a period of 15 months 2 In the USA the American Society of Anaesthesiologists reported an increase in wrong sided block from 2% to 16% 4 There is likely to be significant undereporting 3 Complications include 5 : 1.Increased risk of nerve damage 2.Prolonged recovery 3.Delay in mobilisation 4.Contribution to wrong sided surgery 5.Increased anaesthetic induction time and stress OBJECTIVES RESULTS 30.7% of respondents had been involved in wrong-sided nerve blocks or near-misses in the past. 1. Pre-procedure Verification (on ward) Pre-anaesthetic assessment. Anaesthetic site marking -performed by the professional responsible for the planned procedure - involve the patient in the site marking process -mark is made near or at the procedure site -mark is sufficiently permanent to be visible after skin preparation and draping. A standardised marking system should be agreed either with the use of sticker, clinicians’ initials or coloured marker pen Alternatively, a “Wrong Side” sticker or equivalent can be placed on the opposite site with the help of the patient. 2. WHO sign-in (in anaesthetic room) The person performing the block confirms: -correct patient, correct surgical site, correct nerve block -verified with the use of the surgical consent form -confirmation with the patient 3. Anaesthetic time-out (“Stop before you Block”) -“time-out” just before commencement of procedure -designated member of the team starts the time-out -all team members present -confirm correct patient, correct site & procedure Repeat if the same patient is having a second nerve block at a different place Document the completion of time-out along with the block details ideally incorporating this into the WHO checklist. CONCLUSIONS REFERENCES METHODS  Nearly 1/3 of our anaesthetists had personal experience of a wrong sided block or near miss.  Survey suggests a step-wise process of verification, marking & time-out would be useful in reducing incidence  The development of the proposed guideline will help improve patient safety in this area 1 Alert: NPSA/2009/PSA002/U1; WHO Surgical Safety Checklist – 27 January Safe Anaesthesia Liaison Group Report: wrong site blocks during surgery; November Barach P, Seiden ST & Morley J. Wrong-site anaesthesia adverse events: can they be stopped? Presented at the annual meeting of the American Society of Anaesthesiologists, October 19, 2008, Orlando, Florida, A773 4 Bierstein K. Preventing wrong-site surgery. ASA Newsletter 2007; 71: The Royal College of Anaesthestists; Bulletin 70: November 2011 PROPOSED GUIDELINE An invite to complete the survey was sent to all anaesthetists of any grade in our deanery. Their grades, their frequency in performing peripheral nerve blocks, their involvements of any wrong-sided nerve blocks or near-misses and their awareness of any guidelines at their hospitals were recorded. Free text sections were used for their routine practices in prevention of wrong-sided nerve blocks and suggestions on further improvement. 59.8% of respondents were aware of local guideline at their hospitals, with 19.7% weren’t aware & 20.5% were unsure. What do you usually do to prevent wrong- sided nerve blocks?? (Top 6 responses) What do you think will be useful in preventing wrong-sided nerve blocks?? Confirm with awake patient verbally (before GA) % Check surgical site marking by surgeons % Check consent form % Check again prior to block ("time- out")/Stop before you block % Check with ODP/anaesthetic assistant % WHO check list % *Multiple comments are allowed, so percentages are out of a total of 244 respondents Education Regular workshops Increasing awareness Warning signs 5 Avoid distraction Lock door 58.9% (144) of respondents were consultants, followed by 14.8% (36) ST5-7 & 11.1% (27) ST To survey the anaesthetists in the North Western Deanery on their experiences of wrong-sided nerve blocks or near-misses and their suggestions on how to prevent them from happening in future. 2.To develop a universal guideline for the Deanery.
