INTRODUCTION
Entrustable Professional Activities (EPAs) are a new concept in medical education that has aroused much interest among medical educators. Introduced in 2005, nearly 15 years later it has been the subject of hundreds of publications and, currently, several medical education programs in different countries have incorporated the use of EPAs. However, few studies have been published in the literature in Portuguese. The aim of this paper is to introduce and explain this concept starting with a brief historical review.
Brief historical review
Medicine is one of the oldest and most respected professions in the world. It has been a highly selective career option and very attractive to young people, and those who carry the title of doctor have often been viewed as respectable members of society.1 In many societies, the right to see and treat patients has been limited to well-educated and trained professionals, either in a university community or in a professional association with its own norms and rules.
In the twentieth century, many Western countries started to regulate the medical profession at the national level, assuming responsibilities for the health of the population and the protection of citizens against incompetent medical professional practice. This led to the concept of competency and the identification of components of the medical curriculum. It was only after the establishment of a massive increase in postgraduate training after World War II, and the need to define educational goals in higher education,2 that outcome- and competency-based education became a guiding principle for medical educators.3 - 5 Competency-based medical education was adopted in different countries in the 1990s and early 21st century and its structure has been used to describe the full amplitude of the medical profession in terms of competencies.6 - 10
Particularly in postgraduate training, professional associations such as the Royal Colleges were uncomfortable with the model according to which, within a certain period of time, license to practice would be automatically achieved without any rigorous assessment of training competency. The need to move from the time-based to the competency-based medical education model was felt.11 , 12 The prestigious 2010 Carnegie Foundation’s report on the reform for medical schools and residencies also proposed a model with fixed standards and flexible paths.13
While national regulators of medical training and professional records reinforced requests for medical schools and students to meet the new standards, not everyone agreed. Some clinical educators14 , 15 and students16 - 18 expressed their criticism in the bibliography. For them there was a need to establish a better connection between competencies and daily practice in health care.
What are EPAs and why was the concept created?
The desire to bridge the gap between well-designed competency structure and clinical practice with the patient led to the creation of EPAs.19 The EPAs are units of professional practice that constitute the daily practice of clinicians.20 They can be conceived as responsibilities or tasks that must be performed in patient care. These tasks can be simple or complex. An attending physician or resident in a clinical ward, called at night by the nursing staff, should be able to assess the patient’s clinical worsening and implement actions to stabilize them. This could be an EPA for an intensive care resident. A trainee resident in Obstetrics, if there are no signs of complications, can be trusted to attend to a birth. A sixth-year undergraduate student may be called upon to perform the examination and evaluate a patient with a known chronic condition, if necessary, to perform diagnostic tests, to prepare drug treatment and to do all necessary work which should only be completed and supervised by a member of the hospital’s clinical staff. This can be an EPA. Even a younger student can contribute to health care with simple but meaningful tasks that need not be checked if the student is well trained to do them and report their results.21 EPAs are professional activities that typically have a beginning and an end and are only entrusted to trained personnel. A great part of medical practice can be described as an activity that the professional must be able to perform. What is critical in medical education at the end of the training is that this activity must be performed with safety. This means that student assessment should be focused on the student’s ability to do so and to deal with any unexpected events that might occur during the activity. General competencies, such as adequate communication skills, professionalism and collaborative skills (teamwork) are of critical importance and should be evaluated, but they especially useful to inform the key objectives of training: professional activities.
HOW CAN WE ASSOCIATE EPAS WITH COMPETENCIES?
EPAs comprise the description of a task and do not depend on people. They define a profession in an operational manner.19 , 22 They are a list of tasks that each clinical department, clinical ward or health worker must do on a day, week, or any other period of time. Job descriptions may list general EPAs and task lists apply to those specific things that must occur within a planned time frame.
Competencies describe people. Students who become competent professionals must acquire competencies that include knowledge, skills and attitudes. Professionals have competencies; but they never have EPAs. EPAs and competencies (or competency domains) can be represented using a matrix model ( Figure 1 ).

Figure 1 indicates EPAs at different levels of training and associates them to the most important competency domains (according to the Canadian CanMEDS model), which should be present when performing EPAs.23 This easily proves that an EPA requires multiple competencies from the student, which should be applied in an integrated manner.
Even a clear task, such as obtaining a medical history, combines different competency domains. Professionalism and communication skills are clearly needed, but medical experience is also indispensable for obtaining a guided, efficient and productive history. ( Figure 1 )
ENTRUSTMENT DECISIONS
EPAs can be delegated to students when they are considered ready to perform them. The decision to transfer responsibility to the student has been referred to as the entrustable decision.24 Such decisions occur every day in the real-life clinical setting. An essential component of training is the regular transfer of responsibilities as the situation permits it. The supervising physician may do so when they realize that the student’s skills at that time correspond to the patient’s complexity and the risks of doing so are acceptable. These are referred to as ‘ad-hoc entrustment decisions’.25 In contrast, the ‘summative entrustment decision’ has a certification nature. These are decisions made at the moment and focused on the students’ future responsibilities. In services where the curriculum is constructed with EPAs, summative entrustment decisions constitute permission to exercise an EPA when there is a sufficient level of confidence among the faculty about the student’s capacity to carry out this responsibility.26 The student is assessed regarding their skill and receives rights and duties when engaged in the clinical care of patients.27 While in regular programs, this right is granted at the end of training, by issuing a diploma or license, in the EPA-based curriculum, it is given to separate EPAs at several times throughout the program, i.e. as soon as it is justified, based on the certainty that the student achieved the program objectives for that EPA. Therefore, an EPA-based curriculum can truly be considered a competency-based curriculum and not just a time-based one. In practice, a reasonable expectation would be that most students would be able to perform all EPAs during undergraduate time, but brilliant students could achieve them earlier, while slower students would do it a little later and those who combined clinical training with research or family assignments, or other legitimate activities, could take longer. Studies have shown, however, that programs that invest heavily in training, simulation, supervision, and frequent feedback can shorten the training process.11 , 28
The ‘ ad-hoc entrustment decisions’, even if they happen often, are determined by more factors than one might think at first sight. Clinical supervisors may not always be aware of these factors but may unconsciously measure them. They are grouped into five factors, which include: a) the perception of students’ characteristics, b) the supervisor’s propensity to delegate responsibility, c) the complexity of the EPA, d) the context, and e) the nature of the teacher-student relationship.24 , 29 - 31 Each of these can be further detailed:
The students’ characteristics include specific skills and experience with EPA, but together with them, three other characteristics of professionalism can be perceived 27 , 32 - 34 integrity (veracity and benevolence in reporting to the clinical supervisor), reliability (stable, predictable behavior, and conscientious working attitude) and humility (the ability to observe one’s own limitations and willingness to ask for help when needed). Additionally, the student needs to know how to handle unknown situations.35
Clinical supervisors may differ greatly in how easily they delegate responsibilities to students 24 ; this is reported as depending on the specialty, experience and personality.30
Logically, a more complex EPA will not be entrusted so early to a trainee but an easier and less risky one. This also goes for unusual activities.
The context includes patient complexity, available facilities, time of day or night, staffing requirements, but also the rules of supervision, restrictions of the working hours, and perception of student mentality.36
The relationship between the student and the clinical supervisor must evolve beyond the initial impressions to allow for criticism in entrustment decisions37 , 38 and this relationship in postgraduate studies has been described as a dance that takes place between the experienced resident and the clinical supervisor, when residents reach the end of their training.39
As the ‘summative-entrustment decision’ is of a certification nature, sometimes referred to as the ‘Statement of Awarded Responsibility’ (STAR)19 , it must be based on sufficiently substantiated trust,26 which, to avoid risks of subjectivity, would include an agreement between multiple observers and multiple observations so that entrustment can be justified.
Recommended sources of information include several direct, longitudinal observations, case-based discussions, and the products of evaluations. Additionally, knowledge and skill assessment scores may be considered.40
It is important to note that an entrustment decision implies acceptance of the risk that the student will encounter at the meeting and which cannot be fully predicted. In particular, the case-based discussion41 , a short, focused conversation, usually after an EPA, should thoroughly investigate the student’s understanding about what was done and should include ‘what-if’ questions to understand whether the student would know what to do when facing unexpected or unfamiliar situations.
SUPERVISION LEVELS AS WORKPLACE ASSESSMENT SCALE
Thus far, we have discussed entrustment decisions as dichotomous decisions: to entrust or not to entrust. However, it is very useful to associate entrustment decisions to decreasing levels of supervision. Five main levels are described: Level 1: The trainee is allowed to be present and observe but not perform the EPA; Level 2: The trainee is allowed to perform EPA under direct and proactive supervision present in the room; Level 3: The trainee is allowed to perform EPA without a supervisor in the room, but readily accessible if necessary, e.g., with indirect and reactive supervision; Level 4: The trainee is allowed to work without supervision, Level 5: The trainee is allowed to supervise novice learners. This structure has been widely recommended.19 , 25 , 40 Although the idea of using EPAs has emerged for postgraduate training programs, recently undergraduate programs have started to use them. This has led to detailed levels of supervision.42 , 43Figure 2 provides a more detailed picture.44 , 45 ( Figure 2 )
The Entrustment-supervision (ES)46 scales can have other formats. In the training of anesthesiologists, such scales have been translated into a nine-point mini-clinical evaluation exercise (mini-CEX) scale, which has been shown to increase the reliability of the evaluation.46 This is due to the close association of evaluation practices with the clinic.47 Recently, Weller et al.48 described a nine-point reliability scale that uses colloquial language for anesthesiology supervisors48 : “I am not comfortable leaving the operating room.” “I can take a brief coffee break.” “I can take a break for lunch.” “I have to check in regularly.” “I can start it and leave the room and wait until you ask me for help.” “I trust the student can initially deal with the whole situation.” “I can just review everything with the student beforehand.” “I can leave the room.” “The student can work as a consultant.”
Although it is not the main ES-scale, it is an excellent illustration of the central idea of entrustability scales: aligning assessment with clinical practice.49
BUILDING A CURRICULUM WITH EPA IN PRACTICE
Applying EPA to the medical curriculum can be considered a process that requires several steps.40
EPA identification
Describing a health service curriculum in terms of EPA requires a reflective process. EPAs as units of practice should not be so small or so large. They must be associated with the work in the clinical setting. Several processes have been described to arrive at adequate EPAs, most of which involve local and international expert groups.23 , 43 , 50 - 52 For a complete program, the adequate number of EPAs is considered to range from 20 to 34
Creating full descriptions of EPAs
A complete description of an EPA includes eight sections, and most can be restricted to one or two pages. These sections are:
Title. An adequate title of the activity, which allows its immediate recognition by students and clinicians. It can be a name or include a verb but should not contain an adjective. It should not be written as an educational objective – since it is an activity.
Specifications and limitations. The activity must be specified in detail and must contain no more nor less than what the EPA means. The specifications can be a list of task components. The limitations pertain to the liability restrictions of entrustment decisions such as ‘only concerning hemodynamically stable patients.’
Potential risks in case of failure. Entrustment decisions are risky, and this section is used to specify and understand adverse events that can occur when the task is not performed well.
Association with a prevalent competency scale. The matrix in figure 1 shows the competencies required for a given EPA. This can be mentioned in the third section and can guide the task performance assessment.
Knowledge, skills and attitudes and experience that may be considered before making a summative entrustment decision.
Sources of information to support entrustment decisions. These may be the specification of a satisfactory number of direct observations, longitudinal observations, case-based discussions, and assessment products that support a summative entrustment decision.
Expected level of supervision for this EPA in this educational program. For most EPAs in undergraduate medical school, this level can be level 3 and for postgraduate programs, level 4.
Optionally, an expiration date (or period) may be added. This means that after a summative entrustment decision, if the student has not practiced the EPA for a certain period of time, the decision may expire and the individual (undergraduate or postgraduate student) must be supervised again.
Determining forms of assessment and their rules
In an educational program, rules and regulations must be transparent. These should include the times or periods when students or residents are expected to meet the criteria of all nuclear EPAs. This may include the possibility of adding elective EPAs for advanced and brilliant students.
Establishing individualized itineraries through portfolios
Medical training based on competency should allow for some flexibility and individualization in the learning itineraries, due to differences in students and the contexts of practice settings. In a program for assistant physicians, which has been based on EPAs since 2010, it was found that in this relatively short, 2.5-year, highly individualized program, students starting with a target of 7 EPAs (average 6.8) ended with slightly fewer completed EPAs (6.6 on average) and 1.5 altered EPAs, as calculated among 101 undergraduate students.53 A widely used approach to student achievement follow-up for the recording of the evaluations of entrustment decisions and feedback is the electronic portfolio, and some models are now commercially offered.
Allowing for flexibility in the amplitude or throughout training
A burning question that often arises is how to accommodate flexibility in the practical training programs, particularly in postgraduate training, where students are planned to provide health care in the service and to do so faster or more slowly can seriously interfere with the established rotation and schedule. The organization of flexible and individualized programs is the consequence of true competency-based training, but it must be borne in mind that it may not be easy.
Basically, there are two approaches. One is to update by adapting the schedule. In countries with access to highly regulated postgraduate training (e.g., the United States of America and Canada annually on July 1st) this seems impossible, but it would be possible in other countries where undergraduate students leave medical school at various times throughout the year and the start of the residency program is equally flexible. Additionally, several programs have the capacity to accommodate pregnancy and maternity leave, and some may combine medical training programs and doctoral programs or residency and doctoral programs. These will not have much difficulty in incorporating the flexibility of the competency-based curriculum.
The other approach is not to adapt time but to distinguish nuclear from elective EPAs and vary the EPAs required for graduation in the portfolio. The Dutch radiology program, which was redesigned based on EPAs, offers that. Residents are expected to add a domain of special interest to their set of nuclear EPAs, but it may also be two or, in rare cases, none. An Academic Medicine supplement of March 2018 was fully devoted to all the details of time-varying competency-based education.54
FINAL CONCLUSIONS
The EPAs first appeared in 2005 and have now become popular in postgraduate programs and, more recently, in undergraduate programs.
Specialization programs in psychiatry, pediatrics, internal medicine, family medicine, anesthesiology, emergency medicine and other areas have documented EPA initiatives.22 , 50 , 55 - 59 EPAs in medical undergraduate programs 42 have become a reality in countries such as the United States of America,52 Canada60 and the Netherlands.61 In Alternative Medicine, Nursing, Medical Assistant training, Veterinary Medicine, Dentistry and Obstetrics, the EPAs have been actively developed and have attracted interest even in teacher training programs.62
A specific topic, such as assessment based on the entrustment decision-making is likely to become a research area of interest and, in North America, the concept of Milestones63 will be related to EPAs.
In brief, EPAs are a new and exciting area of study that has not yet fully developed, but that will likely affect the future of competency-based medical education in many countries.64
