Introduction
The oropharyngeal swallow involves a rapid, highly coordinated set of neuromuscular
actions beginning with lip closure and terminating with opening of the upper esophageal
sphincter. The central coordination of this complex sensorimotor task uses a widespread
network of cortical, subcortical, and brainstem structures. Many diseases and disorders
affecting the central swallowing network or downstream peripheral nerves, muscles,
and structures may result in an impaired oropharyngeal swallow, i.e., neurogenic oropharyngeal
dysphagia (OD). In addition, aging is also associated with multifactorial changes
of swallowing physiology for which the term presbyphagia has been coined [1]. OD has
been reported in about 10–27% of older community dwelling residents [2–4]. In the
nursing home, setting numbers are significantly higher and cross the 50% margin, which
is similar to figures reported for older individuals admitted to hospital with a diagnosis
of pneumonia [5]. Disease-specific prevalence data for OD are also substantial. Thus,
disordered swallowing is reported in more than half of acute stroke patients and patients
with traumatic brain injury, at least one-third of patients with Parkinson’s disease
and dementia and a significant number of patients with neuromuscular disorders, such
as amyotrophic lateral sclerosis and myasthenia gravis [6–11]. In view of the demographic
shift, especially with increasing numbers of very old people, i.e., those aged over
85 years, these already alarming figures will further increase in the coming years
since many underlying pathologies, particularly stroke, dementia and Parkinson’s disease,
are age related [12]. It has been estimated up to 16 million US, 40 million EU and
8 million Japanese citizens require care for dysphagia. The clinical consequences
of dysphagia are directly linked to the patient’s overall prognosis, and may include
aspiration pneumonia, malnutrition, and dehydration. In the presence of disordered
swallowing, mortality is increased and elevated rates of infectious complications
have been reported for several medical conditions, such as stroke or Parkinson’s disease,
but are also present in other patient populations [13]. In addition, older patients
discharged from general hospitals with both dysphagia and malnutrition presented a
mortality rate of 65.8% at 1 year follow-up [14].
The ESSD FEES Accreditation Program
The above-mentioned data indicate that swallowing impairment is a nearly ubiquitous
problem in the today’s medical world. Affected patients are either treated as outpatients
or on an inpatient basis, where dysphagia is observed at all levels of care, from
the general ward to the intermediate care/stroke unit and the intensive care unit.
To manage all the needs of patients with dysphagia, two complementary strategies should
be established: first the development of well-coordinated multidisciplinary teams
and dysphagia units in hospitals and second, the creation of a new professional profile,
the deglutologist, to bring together knowledge and skills from different disciplines,
to fully cover the diagnostic and therapeutic needs of our patients with dysphagia.
Usually, the first step in systematic evaluation of OD is a clinical swallowing evaluation.
Patients that show any sign of dysphagia are referred for instrumental assessment
if their condition allows it and if there is potential for change in the clinical
management of the patient.
Together with the videofluoroscopic swallowing study (VFSS), fiberoptic endoscopic
evaluation of swallowing (FEES) is today the most commonly chosen method for the instrumental
assessment of swallowing [15]. In terms of day-to-day practicality, the merits of
FEES are that (i) it can be performed at the bedside, thus facilitating examination
of severely motor-impaired, bedridden or uncooperative patients, for example in the
intensive care unit or the stroke unit; (ii) follow-up examinations can be performed
at short notice and, if necessary, frequently; and (iii) oropharyngeal secretion management
and efficacy of cleaning mechanisms, such as coughing and throat clearing, can be
assessed simply and directly. During recent years FEES has been successfully applied
in diverse patient populations and disease patterns. Among others, studies describing
FEES in stroke and traumatic brain injury patients [16–18], patients with neurodegenerative
(dementia, Parkinson’s disease) [9, 19, 20] and neuromuscular diseases (for example
ALS, myasthenia gravis, myotonic dystrophy) [21–24] as well as head and neck cancers
[25–27] have been published. FEES is also being increasingly applied in pediatrics
[28–30], geriatrics, [31, 32] and intensive-care medicine [33, 34].
Despite the numerous possible applications of FEES and the undisputed need for qualified
dysphagia assessment in this area of expertise, this technique is rarely taught systematically.
For this reason, the European Society of Swallowing Disorders (ESSD) has decided to
offer and organize an interdisciplinary pan-European training curriculum for FEES
in neurogenic and geriatric dysphagia. This ESSD FEES accreditation program expands
on the German FEES curriculum which is in use since 2014 [35, 36].
The ESSD is an international, nonprofit, multidisciplinary society, legally registered
by the Department of Justice of the Generalitat de Catalunya, expedient nº 46,577,
www.myessd.org. The legal framework for this initiative is defined in the aims of
the society as recorded in the Articles of the Association, those directly relevant
to this activity are the following:
To promote care, education and research in swallowing physiology and swallowing disorders.
To represent and promote the field to national and international authorities and societies
and the European Union
To create professional standards of practice and guidelines.
To consolidate the Society as the society for dysphagia and swallowing disorders in
Europe.
Also recorded in the Articles, the activities the ESSD will carry out to achieve these
aims include the following:
Promote the development of guidelines and best practice and recommended reading using
the network of experts and associations
Organize or promote training through workshops and courses
Represent the field to the European Union and Commission and to international and
national institutions and national governments
The ESSD provides an appropriate framework for developing this kind of professional
training and accreditation, being both multidisciplinary and international, and has
sought the endorsement of other medical societies. In addition to accreditation in
FEES in neurogenic and geriatric dysphagia, the ESSD is developing professional accreditation
programs in other methods of instrumental assessment such as VFSS and high resolution
manometry. Given the need for instrumental assessment of dysphagia in neurogenic and
geriatric patients, the multidisciplinary team management needed for dysphagia and
the lack of training in FEES of the professions of the team, ESSD has the scope to
be able to achieve this with the backing of other medical profession societies.
The ESSD FEES accreditation program pursues three aims: First, the definition of quality
standards and systematic procedures, designed to guarantee the consistent performance
of FEES throughout Europe. In the long run, the intended standardization of terminology,
examination algorithms and interpretation of results will not only facilitate professional
communication within a given hospital, but will also contribute to the optimization
of understanding between the various sites involved in the treatment of an individual
patient over time, e.g. acute clinic, rehabilitation clinic, outpatient care; Second,
a formal accreditation program leading to a valorization of FEES as an independent,
clinically relevant and sought-after qualification; Third, to provide a clear pathway
to regulate the use of FEES by several professional domains, inside a multidisciplinary
team, as practiced in other parts of the world and even in other disciplines.
The diagnostics and therapy of swallowing disorders are relevant to many disciplines.
This training curriculum is therefore open to all clinicians with an interest in this
topic. It also offers health care professionals the opportunity to acquire qualifications
in the area of instrumental dysphagia assessment and to expand their range of activities.
At this point, attention should explicitly be drawn to the fact that the present curriculum
addresses neurogenic and geriatric OD. Therefore, neither the diagnostics of structural
changes in the mouth and throat (e.g. tumors or anatomical variants), nor the examination
of swallowing disorders due to such ailments (e.g. structural changes after surgery
or irradiation) are dealt with in detail in this training program and patients with
any of these disorders should be referred to an otorhinolaryngologist or a phoniatrician.
Finally, this training curriculum will provide a thorough education for using FEES
to evaluate the oropharyngeal swallow in neurological and geriatric patients and to
establish a formal diagnosis of OD. It should be noted that management of OD requires
a multidisciplinary team providing further knowledge and skills for complex cases
and rehabilitation planning. The ESSD will evaluate whether more advanced training
should be offered according to the feedback and experience from this basic level.
Prerequisites
The following prerequisites have been defined for qualification in the area of FEES
within this curriculum and will be reviewed by the ESSD:
Two years of clinical practice focused on the care of neurological or geriatric patients
is required for doctors and health care professionals. Three months of this period
shall be completed in a neurological or geriatric department or a facility involving
the care of these patients such as dysphagia or FEES units
Along with the acquisition of the FEES certificate, the following requirements specific
to each professional group must be fulfilled in order to attain the status of a FEES
instructor: allied health professionals must be in possession of at least 5 years
of experience in the area of diagnostics and therapy of neurogenic, geriatric OD.
Physicians must have acquired a specialist title.
Qualification Levels
The ESSD FEES accreditation program is divided into two stages: the FEES certificate
and the FEES instructor certificate.
FEES Certificate
The holder of a FEES certificate is accredited by the ESSD as able to perform FEES
to assess neurogenic, geriatric OD, to prepare the related report and to define clinical
consequences in collaboration with the multidisciplinary team. Key learning objectives
of this educational step are (i) to safely pass the endoscope in a standard setting,
(ii) to know and carry out the standard FEES protocol, (iii) to recognize the main
findings of FEES (iv) to differentiate normal from pathological findings, (v) to recommend
further treatment according to the findings and in the context of the management provided
by the multidisciplinary team.
Training consists of the following sections (Fig. 1):
Either
12 h online education module and 16 h on-site Workshop
Or
24 h on-site Workshop
Plus
FEES practice under direct supervision and
FEES practice under indirect supervision

Online Learning
Twelve hours online learning module on pathophysiology, diagnosis, and management
of OD and its complications will be provided. Graduates of ESSD Postgraduate Diploma
on Swallowing Disorders, www.postgraduateswallowingdisorders.com, do not need to do
this step.
Workshop
The workshop consists of 16 hours of training in theoretical and practical knowledge
(the on-site workshop will be 24 h if the 12 h online module is not implemented).
The theoretical topics covered are listed in Table 1. Handling of the endoscope will
be practiced (a minimum of ten times) using a medical dummy. The participants will
then improve their technical skills by means of reciprocal examination (a minimum
of five times). Interpretation of typical endoscopic findings will be practiced using
suitable video sequences. Each participant will analyze at least 25 sequences independently.
At the end of the workshop candidates will have to pass a theoretical exam on the
online and on-site content.

FEES Under Direct Supervision
The second phase involves performing FEES under direct supervision in a hospital.
Handling of the endoscope as well as planning of the interventions will be practiced
during 30 explorations, and concise reports of the findings will be prepared in each
individual case. These will include standard cases as well as a minimum of five complex
cases. The latter will include patients with compromised respiratory function, tracheotomized
patients, patients whose ability to cooperate is impaired due to ailments such as
aphasia or an acute confusional state, as well as patients displaying motor restlessness
caused by, for example, a movement disorder (Table 2). It is the responsibility of
the participants to find and contract a clinic where they can do this practice. ESSD
will help them find a supervisor in the country they work in but participants need
to have permission to practice in hospitals.

FEES Under Indirect Supervision
During the last stage of the program, 30 FEES will be performed independently and
documented in the training record book. At least 5 will involve complex cases. The
supervisor from the previous stage will be available for questions and will also discuss
critical findings with the trainee.
The education ends with a practical examination which involves performing FEES independently.
In addition, the examinee should write a systematic report, consider additional diagnostic
steps where necessary, and make suggestions regarding further management. Ideally,
detailed rehabilitation planning should be provided in the context of a multidisciplinary
team. The test also comprises assessment and diagnosis of three additional FEES sequences
prepared by the examiner. Finally, selected findings recorded during the training
period are discussed with the examinee (Fig. 2).
Fig. 2
Examination components of the FEES certificate and FEES instructor certificate
FEES Instructor Certificate
The FEES instructor possesses more profound knowledge and skills. He/she has the ability
to independently assess all cases, including complex ones. He/she is licensed to organize
FEES-training seminars, can offer work-shadowing opportunities and is entitled to
administer the theoretical and practical FEES-certificate examinations in agreement
with the ESSD. Key learning objectives of this educational step include (i) to safely
pass the scope in difficult clinical situations, (ii) to adapt the FEES procedure
to the given clinical situation and to use disease-specific protocols, (iii) to explain
the pathophysiology of observed important findings, (iv) to identify subtler pathological
findings, (v) to make more accurate suggestions regarding further management in the
multidisciplinary team context.
To become a FEES instructor, additional systematic practical training is required
that comprises a minimum of 150 FEES, 30 of which must pertain to complex cases. These
evaluations, including complications, must be documented in the FEES training record
book. Difficult diagnoses are to be discussed with the instructor.
At the end of this educational period, a practical examination will be taken in a
hospital. This test includes two FEES, one of which must be a complex case. Besides
implementing the standard FEES protocol, the examinee must also adapt the procedure
as needed without external help, explain his examination steps and be able to implement
special FEES protocols (such as the FEES-Tensilon-Test or the FEES-Levodopa-Test).
The examinee must also be able to develop diagnostic and therapeutic strategies without
assistance. Additionally, he must assess five video sequences prepared by the examiner.
Findings documented throughout the preceding training period will be discussed during
the examination (Table 2). The candidate must also be able to explain and substantiate
the FEES routine established in his institution using appropriate documents (such
as diagnosis forms, clinical algorithms).
The complete FEES-training curriculum is summarized in Fig. 3.

examination, PE practical examination
Regardless of the level of training, the required endoscopies can be performed in
the candidate’s own institution and/or within the scope of work-shadowing opportunities
and workshops in external institutions. Work shadowing is especially meaningful during
the initial stage of training, during which the mediation of technical skills, requiring
intensive personal supervision, is particularly important. For advanced users, workshops
offering discussions on complex cases could be an option, as these are an ideal setting
in which to discuss rare, subtle or difficult-to-interpret findings in a focused manner.
Training Record Book
Complete documentation of the FEES education in the training record book is required.
Task Assignment and Delegation
As stated above, this accreditation program is also open to allied health care professionals,
a group of non-medical professionals. For this reason, the aspects of task assignment
and delegation are briefly addressed here. In principle, this curriculum encourages
the performance of FEES by a multidisciplinary team including physicians and allied
health care professionals. It is the conviction of the ESSD that, within the FEES
team, tasks should be assigned flexibly, taking into account the training level of
each person involved. However, it is important to note that the FEES certificate described
here does not overrule national regulations. Therefore, holders of either the FEES
certificate or the FEES instructor certificate do not automatically acquire the right
to carry out FEES in their home countries as this depends on national regulations.
What the ESSD accredits is that the skills and the knowledge to perform FEES in neurologic
and geriatric patients have been achieved, paving the way for a claim for professional
recognition to widen scope of practice. Whether, and under which conditions, non-medical
professionals are allowed to do FEES is defined by country-specific legal regulations.
Therefore, it is suggested that professionals with an interest in this education should
carefully check those regulations of their home countries before registering.
Applying for the FEES Certificate and the FEES-Instructor Status
Following completion of the different educational steps of this curriculum, requests
for the FEES certificate and the FEES-instructor status can be submitted to the ESSD
FEES accreditation board either by e-mail or regular mail (for further information
with regards to the accreditation board see below).
Transitional Arrangement
Until 31 December 2018, the FEES certificate and the FEES instructor status, including
full entitlement to administer examinations leading to the FEES instructor status,
can be granted within the framework of a transitional arrangement under the conditions
listed below.
Qualifications required for the FEES certificate:
Proof of training in an institution with FEES expertise
2 years of experience in the area of FEES with patients presenting OD
A minimum of 200 performed evaluations
Passing a written onsite exam provided by the accreditation board.
Qualifications required for the FEES instructor certificate:
Five years of experience in the area of FEES with patients presenting OD
A minimum of 500 performed evaluations
Establishment of examination standards within the applicant’s hospital
Internal advanced training for staff members
For physicians specialist title
Passing a written onsite exam provided by the FEES accreditation board.
Exceptionally, holders of comparable certificates from other societies or professions
that include the training of FEES and management of swallowing disorders, such as
otorhinolaryngologists and phoniatricians, may be granted the FEES certificate or
the FEES instructor certificate upon individual application and without sitting an
exam.
All decisions with regards to the transitional arrangement will be taken by the accreditation
board of the ESSD.
Accreditation of Curricular FEES Training Courses
FEES certificate training events planned by FEES instructors must be evaluated and
accredited by the accreditation board. Instructors offering courses with ESSD accreditation
should be members of the ESSD.
Organization and Implementation
All organizational aspects will be managed by the ESSD FEES accreditation board. All
involved medical disciplines as well as health care professionals will be represented
on this board. The following tasks are confined to the accreditation board:
Reviewing applications for the FEES certificate and the FEES instructor certificate
within the transitional arrangement
Reviewing regular applications for the FEES certificate and the FEES instructor certificate
Reviewing and accrediting curricular FEES training courses
Evaluating web-based online material used for FEES courses
Assigning FEES trainees to FEES instructors for practical examinations
