It was developed by the Safer Care Action Team, NHS North East of England. It consists of eight modules dealing with cognitive processing, decision-making, situation awareness, personality types, teamwork, leadership, communication skills, and stress management; these can be delivered in separate sessions or as a single intensive course. This Manual gives detailed and referenced accounts of each subject, and other components of the course are provided in an e-learning package (www.safercare.eu/human/) and a Handbook for participants. Human factors training is widely used in safety-critical industries, but healthcare is a relative late-comer to the field. There are two main differences from other industries that must be addressed. The first, and more obvious one, relates to those issues that are specific to healthcare as opposed to those of primary relevance in other industries. The second is less obvious, but more important. It relates to the fact that healthcare professionals tend to be more sceptical than workers in many other industries – they are disinclined to accept statements of benefit without seeing the evidence. This course has been specially designed with this important difference in mind. iii iv Contributors CLIVE BLOXHAM Clive Bloxham is a consultant pathologist at County Durham and Darlington Hospitals with an interest in cognitive factors in medical practice and how errors occur. GUY HIRST Guy Hirst was a pilot with British Airways from 1972 until 2006 and was one of the pioneers of Human Factors Training in the airline culture. Since 2001 he has been writing and presenting courses in healthcare and is involved in research on healthcare safety. PHIL LAWS Phil Laws is a consultant in intensive care medicine and anaesthesia in Newcastle, and medical lead for the Advanced Critical Care Practitioner Programme and Outreach, with an interest in com- munication, crisis communication for junior doctors and mandatory training for critical care staff. PATRICK MITCHELL Patrick Mitchell is a consultant neurosurgeon in Newcastle upon Tyne with a research interest in surgical safety and decision-making. EMMA NUNEZ Emma Nunez is a registered midwife who now works in patient safety. She is the Safer Care North East Programme manager and chaired the Human Factors Faculty responsible for developing this course. NANCY REDFERN Nancy Redfern is a consultant anaesthetist in Newcastle upon Tyne specialising in obstetric and neuro-anaesthesia, with an interest in medical education, appraisal and mentorship. GAVIN THOMS Gavin Thom is a consultant anaesthetist with interests in perioperative and operative safety, and related human and cultural factors. He is currently joint lead on Project OASIS on surgical safety in South East Asia and recently led the international Global Oximetry Project aimed at improving anaesthetic safety. v vi Introduction Being human, by its very nature, makes us all fallible. The additional titles we bear – doctor, nurse, midwife, pharmacist, dentist, chief executive, non-executive director (the list is endless) as a result of our education, training and technical ability – will never change the fundamental imperfections found among humans. Our day-to-day lives provide numerous opportunities to make mistakes that generally have limited adverse consequences. You might forget to put the bin out on collection day because of some distraction, or you might walk down the stairs with the intention of emptying the washing machine, only to forget what you came down for when you reach the kitchen. These lapses are only minor, no more than an irritation, meaning that you have to make alternative plans for refuse disposal or you have to stop in your tracks and retrace your steps to work out what it was you had meant to do. These kind of mistakes do not harm anyone. However, some lapses carry greater risks. A midwife, for example, driving home in the early hours after finishing her nightshift, pulled to a stop at a red traffic light. As she sat and waited for the lights to change, the CD she was playing came to the end and the player automatically changed to the next disc in the library. At this point she drove off again, right through the red light. She had confused the change in what she heard with the change she was waiting to see in the traffic signals. She laughed about it at the time, but she was well aware of how easily she could have killed or seriously injured herself or someone else. Let us not make the error of thinking that the processes we experience that lead to mistakes in our personal and social lives are any different from the processes we experience that lead to mistakes in our professional life. Why do we tend to think that the title of our professional group removes our fallibility? Why is it that we forget such risks when it comes to delivering some of the most technologically advanced and effective healthcare in the world? What has led us to think this way? When we talk about improving safety and reliability in healthcare, we make regular references to the aviation industry. The aviation industry has considerable knowledge and learning that can be shared with and applied to healthcare, but the industry embarked on a difficult journey when it first introduced human factors training. The following quote is from Jeremy Butler, the General Manager of Flight Training in British Airways at that time. We thank him for allowing us to use his comments here, which reveal a rational, balanced view based on both his own experience and expertise in aviation, and latterly in healthcare. “Flight Ops in British Airways (BA) had for a few years been considering, rather idly, the issues of what we might now call non-technical skills on the flight deck. I had become interested in Human Factors, both at the managerial and front-line levels, and became informed through attending seminars and conferences in the USA. I participated in the United Airlines CRM programme (called something else but I can’t remember the exact name). I was asked by vii Introduction Operating Standards Group (OSG) in BA whether this had any relevance to us. I enjoyed the experience but it was a very psychological course at that time, and I concluded that British pilots were not ready for ‘psychobabble’. Also I believed that the Standard Operating Procedures of BA were greatly superior to those of the manufacturer, which are usually adopted by airline operators. It seemed to me that the principles of the ‘monitored approach’ with workload distribution and shared responsibilities were conducive to achieving safe flight and that Crew Resource Management (CRM) was not necessary in BA. “I believe the Kegworth accident changed the thinking in BA (there was probably active consideration prior to Kegworth, and this confirmed the thinking, but I can’t remember the exact sequence). The Board Air Safety Committee (not sure of the exact name now), decided that we would develop and introduce a CRM programme. The responsibility for this fell to me. This was devolved to various managers and interested flight crew, and we recruited a number of CRM instructors. It is noteworthy that CRM was introduced in BA well before the Civil Aviation Authority (CAA) had made it a requirement (even though it was hugely expensive).

THE GIMLI GLIDER INCIDENT From an article published in Soaring Magazine by Wade H. Nelson If a Boeing 767 runs out of fuel at 41,000 feet, what do you have? Answer: A 132-ton glider with a sink rate of more than 2,000 feet-per-minute and marginally enough hydraulic pressure to control the ailerons, elevator, and rudder. Put veteran pilots Bob Pearson and cool-as-a-cucumber Maurice Quintal in the cockpit and you’ve got the unbelievable but true story of Air Canada Flight 143, known ever since as the Gimli Glider. Flight 143’s problems began on the ground in Montreal. A computer known as the Fuel Quantity Information System Processor manages the entire 767 fuel loading process. The FQIS controls all of the fuel pumps and drives all the 767’s fuel gauges. Little is left for crew and refuelers to do but hook up the hoses and dial in the desired fuel load. But the FQIS was not working properly on Flight 143.

  • 1 Introduction What Is Numeracy? What Makes a Person Numerate?
    Section 1 Introduction 1 1 Introduction What is numeracy? What makes a person numerate? In broadest terms, numeracy (or numeric literacy or quantitative liter- acy) can be viewed as a combination of specific knowledge and skills, which are needed (but do not suffice) to function in the modern world. What other skills, apart from numeracy, do we need to posses? For instance, social intelligence, cross-cultural competency, and new-media literacy. Numeracy involves reasoning from, and about, numeric information (data), which can be presented in a variety of ways (such as numeric, graphic, narrative, visual, and dynamic forms). Inspired in part by questions we routinely ask in mathematics (What is this? Why is this true? How do we know?), we expand numeracy to include critical, evidence-supported thinking, common sense, and logical reasoning in situations and/or contexts that do not explicitly nor implicitly involve numbers or quantitative information. (Examples follow.) In our conceptualization of numeracy, and for the purpose of this course, a numerate person is assumed to be a university student, rather than a general member of our society. (One reason lies in the fact that we must make certain assumptions about the background, mathematical and otherwise.) To make this concept of numeracy more transparent, we now illustrate its aspects in several examples (which are in no way an exhaustive). In the article After 7,500% rally, cryptocurrency founder sells his coins pub- lished in the Globe and Mail, on 20 December 2017, we read “Litecoin dropped about 4 per cent to $ 319 at 1:02 p.m.

I dedicate it to her with my deepest love and gratitude. Thank you for everything, Darling. Andrew Leslie Cole Page i Page ii HOW THIS BOOK CAME ABOUT This project started with a posting for BajanThings.com: “F/O Errol Walton Barrow, Navigator RAF World War II and Prime Minister of Barbados” published in March 2019. Following publication, Melissa Whitney Nelson posted a comment on a Facebook group: Old Time Photos Barbados. She commented that back in 2010 while visiting the UK with her son “she had a chance meeting with a lovely old gentleman with very white hair” at what turned out to be St. Nicolas Church, Great Bookham, Surrey. Following some detective work that “lovely old gentleman with very white hair” was Andrew Leslie Cole; Errol Barrow’s pilot in 88 Squadron 2nd Tactical Air Force (TAF) during World War II. Might Andrew Cole still be alive? Sadly he had died in December 2017. “The Beautiful Blonde in the Bank” is Andrew Cole’s legacy; an unpublished book he wrote in 2001 on his time in the RAF during World War II and flying post war.

  • Gimli Glider from Wikipedia, the Free Encyclopedia
    Software Disasters Gimli Glider From Wikipedia, the free encyclopedia The Gimli Glider aircraft taxiing at San Francisco International Airport in 1985 Air Canada Flight 143 was a Canadian scheduled domestic passenger flight between Montreal and Edmonton that ran out of fuel on July 23, 1983, at an altitude of 41,000 feet (12,000 m), midway through the flight. The Boeing 767 glided to an emergency landing at a former Royal Canadian Air Force base in Gimli, Manitoba, that had been turned into a motor racing track. This unusual aviation incident earned the aircraft the nickname "Gimli Glider".[1] The subsequent investigation revealed that a combination of company failures, human errors and confusion over unit measures had led to the aircraft being refuelled with insufficient fuel for the planned flight. https://en.wikipedia.org/wiki/Gimli_Glider At the time of the incident, Canada's aviation sector was in the process of converting to the metric system. As part of this process, the new 767s being acquired by Air Canada were the first to be calibrated for metric units (litres and kilograms) instead of Imperial units (gallons and pounds). All other aircraft of the company were still operating with Imperial units. For the trip to Edmonton, the pilot calculated a fuel requirement of 22,300 kilograms (49,200 lb). A floatstick check indicated that there were 7,682 litres (1,690 imp gal; 2,029 US gal) already in the tanks. To calculate how much more fuel had to be added, the crew needed to convert the volume (litres) in the tanks to a mass (kilograms), subtract that figure from 22,300 kg and convert the result back into a volume.

But the FQIS was not working properly on Flight 143. The fault was later discovered to be a poorly soldered sensor. An improbable sequence of circuit-breaking mistakes made by an Air Canada technician independently investigating the problem defeated several layers of redundancy built into the system. This left Aircraft #604 without working fuel gauges. In order to make their flight from Montreal to Ottawa and on to Edmonton, Flight 143's maintenance crew resorted to calculating the 767's fuel load by hand. This was done using a procedure known as dipping, or "dripping" the tanks.
