We propose a systematic and complete inspection of the bronchial segments, splitting the bronchoscopy into four landmarks to help guide novice bronchoscopists through the bronchial maze. As more specific guidelines that govern bronchoscopy training are needed14, we propose that our systematic and stepwise approach should be evaluated using three basic outcome measures: DC, SP, and PT. 
DC and PT are established outcome measures and the first used when evaluating broncho...

Lung cancer is the leading cause of cancer mortality1. Flexible bronchoscopy is essential to navigate through the bronchial tree and identify the correct segments for the diagnosis and staging of lung cancer and allocation to the correct treatment for the patient2. Lower yields of diagnostic biopsy material, higher complication rates, and increased patient discomfort are seen in the early part of a trainee&#39;s learning curve3,4,5. To ensure independent/unsupervised practice on patients, satisfactory educational levels must be met. A training modality to ensure basic competence is simulation-based mastery learning, where the trainee practices until proficiency criteria are met6. Several tools have been developed to assess bronchoscopy performance7,8, and the following performance measures have been established: (1) diagnostic completeness (DC)-proportion of visualized segments9; (2) structured progress (SP)-number of segments visited in the correct progression order10; and (3) procedure time (PT)-time from passing through the vocal cords to the end of the procedure9.
Novice bronchoscopists can be confused by the maze, looking like similar bronchi, and several fail to complete a course in simulation-based bronchoscopy11, even though it has been identified as the most important technical procedure to learn in pulmonary medicine12. Therefore, through this protocol, we propose a stepwise, structured progression through the bronchial tree (Figure 1), relying on four landmarks as a guide. We suggest that novice operators should be taught according to this approach to ensure visualization of all the bronchial segments in a structured way, in the shortest amount of time, with correct handling of the scope.

systematic bronchoscopy: the four landmarks approach

Flexible bronchoscopy is a technically difficult procedure and has been identified as the most important procedure that should be integrated into a simulation-based training program for pulmonologists. However, more specific guidelines that govern bronchoscopy training are needed to meet this demand. To ensure patients a competent examination, we propose a systematic, stepwise approach, splitting the procedure into four &#34;landmarks&#34; to support novice endoscopists navigating the bronchial maze. The procedure can be evaluated based on three established outcome measures to ensure a thorough and effective inspection of the bronchial tree: diagnostic completeness, structured progress, and procedure time.
The stepwise approach relying on the four landmarks is used at all simulation centers in Denmark and is being implemented in the Netherlands. To provide instant feedback to novice bronchoscopists when training and to relieve time constraints from consultants, we suggest that future studies should implement artificial intelligence&#160;as a feedback and certification tool when training new bronchoscopists.

Systematic Bronchoscopy: the Four Landmarks Approach

This protocol provides novice bronchoscopist with a memorable way to learn how to navigate the bronchial tree using the four landmarks approach. For the unexperienced operator is quite difficult to find the way in the bronchial three when performing a bronchoscopy. We have developed a four-landmark approach, meaning that you should find four landmarks and you can always go back to the four landmarks when you lose your way, and then you can proceed.And we use the four landmarks in connection with the angles. This is the distal end of the endoscope, this is a handle, so when I turn my wrist, I can turn the distal end of the endoscope in different angles. And these angles, we connect with the four landmarks.With the development of artificial intelligence, we hope to develop an automatic bronchial identification system that can help novice bronchoscopist to identify the individual segments and ensure a full inspection of the bronchial tree. Bronchoscopy has historically been taught with a see one, do one, teach one"approach. But with this protocol, we present a standardized way of teaching bronchoscopy.

The four landmarks approach has been taught at CAMES since 2011, where the simulation-based bronchoscopy course is concluded by passing a finalizing test13. From 2015-2017, 77 participants entered the course, of which only 33 (43%) completed it11. The low completion rate was due to several factors: time constraints, the course not being mandatory, maternity leave, and no protected time to train. Of those who completed the course, 14 (42%) found the most important factor for...
