Overview and Justification
Esophagogastroduodenoscopy (EGD) is an endoscopic procedure that is useful for the diagnosis and treatment of conditions of the upper gastrointestinal (GI) tract. It is a tool that many family physicians use to assist with diagnosing esophageal, gastric, and duodenal pathologies, some of which can only be diagnosed with direct visualization. In fact, for the diagnosis of upper GI tract inflammations, ulcers, and neoplasms, the sensitivity and specificity of EGD are greater than those of radiographic studies.1
For many years, family physicians have demonstrated the ability to learn EGD and perform the procedure safely and effectively in institutional and office settings.2-5 Their complication rates compare favorably with others in the GI literature.6-9 Performing EGD increases family physicians’ knowledge of the anatomy and physiology of the upper GI tract and their ability to detect significant upper GI pathology. As physicians are under increasing pressure to work in the most efficient and cost-effective manner possible to make accurate diagnoses and develop efficacious treatment plans, EGD is a useful tool in the family physician's armamentarium.
Because family physicians practice in all regions, including rural and underserved areas, their ability to perform EGD improves patients’ access to care. Patients also benefit from more rapid diagnosis and treatment, as well as enhanced continuity of care. In addition, family physicians may find that the benefits of performing upper GI endoscopy include increased patient satisfaction, better working relationships with gastroenterologist colleagues, improved understanding of the pathology in individual cases, and a greater comfort level with chosen treatments.
Section I - Scope of Practice for Family Physicians
Esophagogastroduodenoscopy can be a natural extension of the comprehensive care provided in a family medicine practice. Gastrointestinal complaints are often first reported to a family physician. Since family physicians are trained to diagnose, treat, and, if necessary, appropriately refer patients who have GI disorders, knowing when EGD is required is one aspect of their role.
Family physicians choose a personal scope of practice based on factors that include their training experiences, their practice interests, and the needs of their patient populations. Therefore, individuals must assess the appropriateness of performing EGD in their practice. As with all clinical procedures, family physicians should consider the safety, purpose, and potential outcomes of an EGD so that it can be performed in an appropriate setting.
EGD is safe and rarely causes significant physical stress for the patient. However, IV sedation does carry a measurable risk and significant post-procedure observation is required. Physicians who perform in-office procedures requiring IV sedation should be able to provide the same level of care that is available in an outpatient or hospital GI lab. This includes appropriate personnel trained in resuscitation and airway management during both the procedure and recovery, as well as telemetry, pulse oximetry, and end-tidal CO2 monitoring. Family physicians performing EGD may need to obtain privileges to provide moderate sedation in accordance with state regulations and/or hospital or facility requirements.
The Society of American Gastrointestinal and Endoscopic Surgeons (SAGES) recommends that patients being considered for endoscopy in the office setting should be evaluated according to the American Society of Anesthesiologists (ASA) physical status classification system.10 The guidelines state that patients who have an ASA score of III (i.e., severe systemic disease, such as chronic obstructive pulmonary disorder [COPD] or poorly controlled diabetes11) should be further assessed to determine the impact of their specific health condition(s) on the risk of anesthesia and the endoscopic procedure in the office setting.10 According to SAGES, patients who have an ASA classification of IV should not undergo an in-office endoscopic procedure.
Section II - Clinical Indications
There are numerous indications for EGD, as noted on the list of indications for GI endoscopy from the American Society for Gastrointestinal Endoscopy (ASGE) (Table 1).

Section III - Training Methodology
Family physicians can obtain EGD training through a family medicine residency or a post-residency fellowship. The Society of Teachers of Family Medicine (STFM) Group on Hospital Medicine and Procedural Training includes EGD on its list of recommended advanced procedures that are within the scope of family medicine and require focused training (in residency or fellowship) in order for residents to be able to perform them independently by graduation.12 A task force of Council of Academic Family Medicine (CAFM) member organizations and experienced faculty and program directors published a consensus statement for procedural training in family medicine residency that includes EGD as one of the more complex or advanced procedures for which training may be offered to interested residents in some family medicine residencies.13
Other options for obtaining EGD training include preceptorship, self-study resources, and CME activities or conferences. The AAFP and its chapters have provided hands-on CME opportunities focused on clinical procedures for decades. In fact, the first national course in EGD for family physicians was sponsored by the AAFP in 1989. Other organizations also offer procedural skills training through accredited CME activities and conferences. Any training approach should develop both the cognitive skills involved in knowing when to perform EGD and how to properly interpret and manage findings, and the technical skills involved in safely performing the procedure. EGD training should also address how to recognize and promptly treat procedure-related complications.
Section IV - Testing, Demonstrated Proficiency, and Documentation
The amount of EGD experience needed to gain and maintain proficiency is user dependent and related to local credentialing and privileging guidelines. Core cognitive and motor skills recommended for achieving competence in the performance of EGD are listed in Tables 2 and 3.

After the completion of upper GI endoscopy, appropriate documentation of the procedure is necessary for continuing care of the patient, medicolegal reasons, and billing. Documentation can be performed by dictating or typing a complete report or by using an endoscopy report template that includes the appropriate indications, medications, findings, and pathology. This type of documentation is also helpful when additional clinical privileges are requested and in clinical studies on EGD.
Section V - Credentialing and Privileges
Family physicians should document all significant training and experience so that this information can be reported in an organized fashion.14 It is the AAFP’s position that clinical privileges should be based on the individual physician's documented training and/or experience, demonstrated abilities, and current competence, and, whenever possible, be evidence based.15 This perspective is in line with the policies of other organizations with influence on credentialing and privileging.
The American Medical Association (AMA) policy on patient protection and clinical privileges states, in part, “Concerning the granting of staff and clinical privileges in hospitals and other health care facilities, the AMA believes: (1) the best interests of patients should be the predominant consideration; (2) the accordance and delineation of privileges should be determined on an individual basis, commensurate with an applicant's education, training, experience, and demonstrated current competence. In implementing these criteria, each facility should formulate and apply reasonable, nondiscriminatory standards for the evaluation of an applicant's credentials, free of anti-competitive intent or purpose.”16
The Joint Commission's standards also require that the decision to grant or deny privileges, and/or to renew existing privileges, must be an objective, evidence-based process in which there are no barriers to granting privileges for a given activity to more than one clinical specialty. The standards state, “Credentialing involves the collection, verification, and assessment of information regarding three critical parameters: current licensure; education and relevant training; and experience, ability, and current competence to perform the requested privilege” [MS.06.01.03].17 All of the criteria should be "consistently evaluated for all practitioners holding that privilege” [MS.06.01.05].17
According to the American Association for Primary Care Endoscopy (AAPCE), "credentialing should not be limited to specific medical specialties.”18 The AAPCE also states, “Credentialing should be based upon demonstrated proficiency rather than a specified number of procedures performed during training.”
Once a hospital determines the experience it will require to qualify for a privilege, it must confirm current competence. The AAFP believes this can be efficiently and fairly achieved through a requirement for references. The reference should have firsthand knowledge of the applicant’s ability to perform EGD competently. The reference’s attestation to competence affirms that the applicant’s training and experience have been adequate for the procedure and individual under review. If, after reviewing references, the hospital still has questions about an individual’s competence, a period of proctoring to observe performance may be appropriate.
This process protects patients and, when uniformly applied, provides a fair mechanism for a hospital to grant a particular privilege. Artificial and arbitrarily high experience requirements should not be created as barriers to the privileging of family physicians. When a minimum volume threshold is required in specific privileging instances, it should be evidence based. If there are not sufficient data, a consensus opinion of experts from within the specialty may be necessary until an evidence-based recommendation becomes available.15 For example, the AAPCE states that if a hospital chooses to require a specific number of procedures during training, the requirement should not exceed 35 EGDs.18
Table 4 lists recommended steps for family physicians applying for GI endoscopy privileges. Privileges for invasive procedures are usually granted provisionally with the requirement that the physician submit progress reports at designated intervals (e.g., three months, six months, one year). In a hospital departmentalized by specialty, the family medicine department should monitor these progress reports for department members and make recommendations for advancement from provisional privileges to active privileges.
To ensure continuous monitoring of quality, physicians may be required to submit an annual census of all invasive procedures that lists any complications that arise. This list should be reviewed by the department chair or a designee. Active privileges are renewed every one to two years by the authority of the department chair.

Section VI - Miscellaneous Issues
A. Public health implications
Little is known concerning the public health implications of family physicians performing EGD. However, it is known that patients, particularly in rural areas, often have better access to family physicians than to other specialists. Improved access to EGD can lead to more efficient diagnosis and treatment, as well as greater patient convenience.
B. Current research agenda
Research concerning EGD in primary care has predominantly comprised case series and descriptive studies that have shown family physicians can safely, accurately, and effectively perform EGD.
Although the findings from this type of research are helpful, evidence is needed from randomized controlled trials and other more powerful study designs. The AAFP supports the need to conduct and publish research regarding the performance of EGD by family physicians. In particular, research is needed to document benefits and harms of the procedure, patient preferences, costs and savings, utilization, and alternatives.
C. Relationships with other organizations
AAFP policy states, “The AAFP seeks to work collaboratively with other specialty societies, when appropriate, concerning issues of procedure skills, including but not limited to: training, privileging and credentialing, and joint political action.”20 Unfortunately, in the past, some specialty societies have been unwilling to work cooperatively with the AAFP on endoscopy issues. In such situations, the AAFP has had no choice but to develop its own educational programs. It would be ideal if the AAFP and other specialty organizations could work together to improve patient care by disseminating information to educate all physicians. The AAFP welcomes opportunities to partner with other groups that have members who perform EGD.
