Patients on ECMO are monitored 24/7 by a team of highly trained ECMO team comprising nurses, physicians, respiratory therapists, and perfusionists promptly intervening to any potential emergency situation. Simulation-Based Training (SBT) allows clinicians to experience and practice realistic hands-on procedures and scenarios without any risk. In ECMO, cannulation is a critical procedure performed to externally reroute the blood flow so it can be re-oxygenated by the ECMO machine before being recirculated through the patient's body. In a close collaboration with Hamad Medical Corporation (HMC), this project aims to develop a cost effective, realistic, and user-friendly ECMO simulator focusing on the venous and arterial cannulation procedure, The main features of this simulator include cannulation emergencies caused by low pressure flow, excessive force, recirculation, or mispositioned wire/cannula. Therefore, the ECMO cannulation simulator will not only greatly contribute to the initial and ongoing local training of HMC ECMO clinicians but also contribute to improving patient care by lowering the risks associated with the cannulation process

For further information see: https://creativecommons.org/licenses/by-nc-nd/4.0/This invited review article was presented orally on the occasion of the South West Asian Chapter conference of the Extracorporeal Life Support Organization (ELSO) held in New Delhi, India in January 2018. It has an educational focus on the topic of extracorporeal membrane oxygenation (ECMO), which is increasingly being used as a lifesaving bridge therapy. A case is being made regarding the adage “practice makes perfect” to be considered in the context of simulation-based education to ensure patient safety. Technology-enhanced simulation-based deliberate practice should be used more commonly to support clinicians in the development of all their professional skills. This is an ethical imperative that may be addressed using low-cost simulation modalities that are sometimes proven to be as effective as more expensive approaches. Educators can now design their programs according to published best practice standards for the benefit of their learners, and ultimately the patients they care for. Simulation-based education clearly has a place and important role to play in preparing ECMO teams dealing with routine procedures as well as emergency situations. Several solution and approaches are being presented alongside innovative work currently being done in collaboration between a regional ELSO center of excellence and an academic institution. This innovative simulator is composed of several modules serving different functions required for the simulation of ECMO emergencies at a much lower cost than using the real machine and its various expensive disposable components.Peer reviewedFinal Published versio

An evaluation of an educational intervention to reduce inappropriate cannulation and improve cannulation technique by paramedics

Background: Intravenous cannulation enables administration of fluids or drugs by paramedics in prehospital settings. Inappropriate use and poor technique carry risks for patients, including pain and infection. We aimed to investigate the effect of an educational intervention designed to reduce the rate of inappropriate cannulation and to improve cannulation technique. Method: We used a non-randomised control group design, comparing two counties in the East Midlands (UK)as intervention and control areas. The educational intervention was based on Joint Royal Colleges Ambulance Liaison Committee guidance and delivered to paramedic team leaders who cascaded it to their teams. We analysed rates of inappropriate cannulation before and after the intervention using routine clinical data. We also assessed overall cannulation rates before and after the intervention. A sample of paramedics was assessed post-intervention on cannulation technique with a ‘‘model’’ arm using a predesigned checklist. Results: There was a non-significant reduction in inappropriate (no intravenous fluids or drugs given) cannulation rates in the intervention area (1.0% to 0%) compared with the control area (2.5% to 2.6%). There was a significant (p,0.001) reduction in cannulation rates in the intervention area (9.1% to 6.5%; OR 0.7, 95% CI 0.48 to 1.03) compared with an increase in the control area (13.8% to 19.1%; OR 1.47, 95% CI 1.15 to 1.90), a significant difference (p,0.001). Paramedics in the intervention area were significantly more likely to use correct hand-washing techniques post-intervention (74.5% vs. 14.9%; p,0.001). Conclusion: The educational intervention was effective in bringing about changes leading to enhanced quality and safety in some aspects of prehospital cannulation

Addressing the challenges of ECMO simulation

This document is the Accepted Manuscript. The final, definitive version of this paper has been published in Perfusion, May 2018, published by SAGE Publishing, All rights reserved.Introduction/Aim: The patient’s condition and high-risk nature of extracorporeal membrane oxygenation (ECMO) therapy force clinical services to ensure clinicians are properly trained and always ready to deal effectively with critical situations. Simulation-based education (SBE), from the simplest approaches to the most immersive modalities, helps promote optimum individual and team performance. The risks of SBE are negative learning, inauthenticity in learning and over-reliance on the participants’ suspension of disbelief. This is especially relevant to ECMO SBE as circuit/patient interactions are difficult to fully simulate without confusing circuit alterations. Methods: Our efforts concentrate on making ECMO simulation easier and more realistic in order to reduce the current gap there is between SBE and real ECMO patient care. Issues to be overcome include controlling the circuit pressures, system failures, patient issues, blood colour and cost factors. Key to our developments are the hospital-university collaboration and research funding. Results: A prototype ECMO simulator has been developed that allows for realistic ECMO SBE. The system emulates the ECMO machine interface with remotely controllable pressure parameters, haemorrhaging, line chattering, air bubble noise and simulated blood colour change. Conclusion: The prototype simulator allows the simulation of common ECMO emergencies through innovative solutions that enhance the fidelity of ECMO SBE and reduce the requirement for suspension of disbelief from participants. Future developments will encompass the patient cannulation aspect.Peer reviewe

Systematic review of new medics’ clinical task experience by country

OBJECTIVES: There is a need for research which informs on the overall size and significance of clinical skills deficits among new medics, globally. There is also the need for a meta-review of the similarities and differences between countries in the clinical skills deficits of new medics. DESIGN: A systematic review of published literature produced 68 articles from Google/Scholar, of which 9 met the inclusion criteria (quantitative clinical skills data about new medical doctors). PARTICIPANTS: 1329 new medical doctors (e.g., foundation year-1s, interns, PGY1s). SETTING: Ten countries/regions. MAIN OUTCOME MEASURES: 123 data points and representation of a broad range of clinical procedures. RESULTS: The average rate of inexperience with a wide range of clinical procedures was 35.92% (lower CI 30.84%, upper CI 40.99%). The preliminary meta-analysis showed that the overall deficit in experience is significantly different from 0 in all countries. Focusing on a smaller selection of clinical skills such as catheterisation, IV cannulation, nasogastric tubing and venepuncture, the average rate of inexperience was 26.75% (lower CI 18.55%, upper CI 35.54%) and also significant. England presented the lowest average deficit (9.15%), followed by New Zealand (18.33%), then South Africa (19.53%), Egypt, Kuwait, Gulf Cooperation Council countries and Ireland (21.07%), after which was Nigeria (37.99%), then USA (38.5%), and Iran (44.75%). CONCLUSION: A meta-analysis is needed to include data not yet in the public domain from more countries. These results provide some support for the UK General Medical Council’s clear, detailed curriculum, which has been heralded by other countries as good practice

A comparative study between visual, near infrared and infrared images for the detection of veins for intravenous cannulation

The process of identification and locating of veins plays an important role to reduce health care cost and suffering of patients during intravenous cannulation. This paper compares between three technologies to assess their suitability and capability for the detection of veins. Three types of cameras are used in this study, a visual camera, an infrared camera and a near infrared camera. The collected data has then been subjected to analysis and comparison using different image processing techniques, namely grayscale, invert grayscale, histogram equalisation, edge detection (difference of Gaussians) and unsharp mask enhancement to improve the visualisation of veins. In this study, the near infrared images supported by suitable LED illumination has been found to be the most effective technology and the most cost effective for the visualisation of veins
