3 Background Knee aspiration is a skill all Foundation Doctors (FDs) are expected to perform safely and competently Previously an essential skill for foundation trainees Currently not on the list of procedures required to complete foundation training (1) This has resulted in a lack of teaching of the procedure, and a lack of confidence in trainees to perform it However, it is generally considered and easy and safe procedure compared to more invasive investigations performed by FDs. Data suggests that this has lead to; Delays in referral to specialities Distorted microbiology results caused by the administration of antibiotics prior to joint aspiration (2)

4 Knee Aspiration Aspiration of the knee joint may be performed for the diagnosis of an unexplained effusion or the evacuation of a painful effusion (3) Several approaches documented in the literature (superior lateral approach used within this setting) Steps: Patient in supine position with knee in extension Palpate the knee to identify the and mark the site Clean and prep the area Strict aseptic non-touch technique Attach a large (20-60ml) syringe to an gauge needle Stretch the skin with the one hand and insert the needle in to the joint whilst gently aspirating Withdraw the needle once completed Place sample correct sample pots as required by the trust Dispose of needle in sharps bin Dress the injection site Accurately label the samples and sent to the lab accordingly

6 Near Peer Tutoring Passage of knowledge between persons at similar stage of training Typically two to five years ahead of the trainee (4) Comparable insights and experience (4) Well-accepted amongst trainees (5) Useful for tutors to improve their teaching skills (5)

7 Aim Address the lack of knowledge and technical ability, and the lack of confidence in performing knee joint aspiration by Foundation Doctors

8 Method We designed a teaching session incorporating a mixed educational approach (6) Two separate teaching sessions, each lasting two hours, were given to a group of foundation year 2 (F2) doctors from Royal London, Whipps Cross, St Barts and Newham General hospitals Facilitated by consultants, registrars and clinical skills trainers The aim was to achieve a low trainee to trainer ratio

9 Course Outline Pre course evaluation and questionnaire Case based scenarios in a lecture format Tutorial on knee aspiration Practical sessions Post course evaluation and questionnaire

10 Pre Course Evaluation Only one trainee had aspirated a knee joint prior to the session 26.67% of trainees they had no knowledge 46.67% of the trainees never received teaching related to knee aspiration

11 Pre Course evaluation How were you originally taught knee joint aspiration See one, do one Internet Reading Clinical Skills/Simulation Lab No previous teaching

13 Self Rated Confidence Scores (Pre-Intervention) Indications Asepsis Technique Differential Dx Complications/Risks Interpreting Pathology No confidence Minimal Confidence Some Confidence Considerable Confidence

14 Case Based Scenarios Interactive lecture focusing on two common, clinically significant cases; gout and septic arthritis The use of clinical questions and Buzz Groups to promote small group discussion and interactivity amongst students Relating the topic to clinical practice and discussion of further investigations and management

15

16 Case Example 45 year old Bengali lady 2 day history of right knee swelling and pain No history of trauma, no recent travel. Feverish Recently been treated for a sexually transmitted disease. Past medical history hypertension. Drug history No known allergies, Ramipril. Social history lives alone and works as a receptionist. She smokes 25/day and doesn t consume alcohol. Family history mother has rheumatoid arthritis

17 Red hot swollen knee Range of motion is painful and is restricted from 15 degrees to 40 degrees of flexion. Patella tap test is positive

18 What are you differential diagnosis from the history and examination? Synovial fluid colour yellow, turbid. Volume 40 mls What are your thoughts about the sample fluid? What tests would you send the sample for? Routine or urgent basis?

19 Practical Sessions Pre-course reading material was provided prior to the course; Aspiration and Injection of the Knee Joint: Approach Portal Part Task simulators were used to mimic a real life knee joint Standard superior-lateral approach used which is shown to be 91% (95 CI) effective (3) Other commonly used approaches were discussed The verbal consenting process was reviewed Students performed the procedure under supervision with one-to-one feedback

20 Practical Sessions

21 Post Course Feedback 16 Self Rated Confidence Scores (Post Intervention) Indications Asepsis Technique Differential Dx Complications/Risks Interpreting Pathology No Confidence Minimal Confidence Some Confidence Considerable Confidence Expert Confidence

22 Overall Confidence in Performing Knee Arthrocentesis (Pre and Post Intervention Comparison) Post-Intervention No Confidence Minimal Confidence Some Confidence Considerable Confidence Expert Confidence Pre-Intervention Pre-Intervention Post-Intervention

23 Questions 1. What is the optimal approach when aspirating the knee joint? 2. What is the normal range of serum urate? 3. What is the most common causative organism in adult septic arthritis? 4. Which gene is implicated in Reiter s syndrome? (Reactive arthritis)

24 Results Everyone showed improvement Average pre course score was 63.3% Average post course score was 78.56% Average Improvement of 15.25%

25 Effective teaching method Strongly Disagree Disagree Neither Agree nor Disagree Agree Strongly Agree

26 Conclusions Knee aspiration is an essential skill for foundation doctors to perform. However the majority of trainees do not feel confident in doing so Near Peer tutoring was identified as a effective teaching method Real-time feedback, interactive discussion and simulation based training was used to provide comprehensive Overall improvement in knowledge, technique and confidence was achieved, as evidenced by pre and post course questionnaires and evaluation forms
