Brief Summary

Endoscopic ultrasound (EUS) is a mini-invasive diagnostic procedure in the work-up of various suspicious malignancies. The learning curve of EUS is regarded long but so far the literature of this topic is minimal. Few studies have been published and there are no standardized or validated methods to perform a systematic assessment of endosonographists in training. This study is an observational study dealing with the matter of assessing endosonographists in training.

Detailed Description

Sahlgrenska Univeristy Hospital is tertiary university endoscopy center. At our endoscopy unit physicians/endoscopists train EUS under the supervision of an experienced endosonographist. Endosonographists examining patients referred for a routine, clinical EUS at the Sahlgrenska Univeristy hospital are candidates for being study subjects. Patients will not be examined by the study endosonographists if supervision is lacking.

External, collaborating centers will be invited to participte in the study given that the study inclusion criteria and ethical standard will be ensured.

The investigators of this study have developped a score sheet for the assessment of endosonographists in training to be used in a standard clinical setting. The score sheet is to be used by both the endosonographist in training (performer) for self-assessment and by the supervisor (observer) for assessment of the performer.

First, background data of the performer is recorded (pervious endoscopy experience etc). Then the performer starts the examination under the guidance of the observer. The observer performs continuous evaluation and assessment of the performer according to the skill parameters (N=5) of the Observer score sheet. Each parameter is ranked on a 1-5 scale (1=non-satisfactory performance, 5= excellent performance). Finally the observer is taking over, reevaluates the findings of the performer and finishes the examination.

After the examination the performer fullfills the Performer score sheet. Finally, both the performer and the observer record their preliminary diagosis of the lesion examined.

Adverse events and complications are recorded.

A follow-up of the medical records of the patient is performed 8 weeks after the EUS-examiantion with respect to the final diagnosis of the lesion of interest. The reference standard is set to best available combination of surgery, pathology and imaging reports. The performer´s assessment of the diagnosis is the categorized as CORRECT or FALSE. A correct diagnosis equals 3 Points and a false diagnosis equals 0 Points.

Results in terms of the total and mean score of all perfomers is calculated and collected in a study database. Feasibility of the study assessment sheet is evaluated. Statistical analysis of categorical data is finally applied for evaluating the results with respect to the progress and learning curve of the study participants.
