    Determination of Face and Content Validity of Cadaveric Model for Holmium Anatomic Endoscopic Enucleation of the Prostate Training: An ESUT AEEP Group Study
    (ELSEVIER, 2021-01-01) Tunc, Lutfi; Bozzini, Giorgio; Scoffone, Cesare Marco; Guven, Selcuk; Hermann, Thomas; Porreca, Angelo; Misrai, Vincent; Ahyai, Sascha; Zor, Murat; Aksoy, Emin; Gozen, Ali S.
    Background: Bench and virtual reality nonbiological simulator models for anatomic endoscopic enucleation of the prostate (AEEP) surgery have been reported in the literature. These models are acceptable but have limited practical applications. Objective: To validate a fresh-frozen human cadaver model for holmium AEEP training and assess its content validity. Design, setting, and participants: Holmium AEEP operations on fresh-frozen cadavers performed by an experienced surgeon were recorded, and a video, including the main steps of the operation, was produced. Outcome measurements and statistical analysis: The video and an accompanying questionnaire were subsequently distributed electronically to ESUT AEEP study group experts and associates (N = 32) for assessment of the AEEP training model. A ten-point Likert global rating scale was used to measure the content validity. Results and limitations: A total of 26 answers were returned (81\%). The experts agreed on the model's suitability for AEEP training (mean Likert score: 8). According to the responses, ``identifying anatomic structures and landmarks{''} was the most valuable aspect of the model in terms of AEEP training (median Likert score: 9). Conversely, the experts found the model's ability, in terms of demonstrating laser and tissue reactions, to be weak (median Likert score: 6) Conclusions: Based on the content validity assessment, the fresh-frozen cadavertraining model for laser AEEP seems to be a promising model for demonstrating and learning the correct prostate enucleation technique. Patient summary: An increasing number of researchers have proposed that anatomic endoscopic enucleation of the prostate (AEEP) should replace transurethral resection of the prostate surgery and become the gold standard for treatment of bladder outlet obstruction due to benign prostatic hyperplasia. AEEP requires anatomic familiarity for enucleation, technical knowledge, and a solid training program before starting with the first cases. This is the first cadaver study to assess the content validity of a fresh-frozen human cadaver model for AEEP training. (C) 2021 The Authors.

    Performance Monitoring via Functional Near Infrared Spectroscopy for Virtual Reality Based Basic Life Support Training
    (FRONTIERS MEDIA SA, 2019-01-01) Aksoy, Emin; Izzetoglu, Kurtulus; Baysoy, Engin; Agrali, Atahan; Kitapcioglu, Dilek; Onaral, Banu
    The use of serious game tools in training of medical professions is steadily growing. However, there is a lack of reliable performance assessment methods to evaluate learner's outcome. The aim of this study is to determine whether functional near infrared spectroscopy (fNIRS) can be used as an additional tool for assessing the learning outcome of virtual reality (VR) based learning modules. The hypothesis is that together with an improvement in learning outcome there would be a decrease in the participants' cerebral oxygenation levels measured from the prefrontal cortex (PFC) region and an increase of participants' serious gaming results. To test this hypothesis, the subjects were recruited and divided into four groups with different combinations of prior virtual reality experience and prior Basic Life Support (BLS) knowledge levels. A VR based serious gaming module for teaching BLS and 16-Channel fNIRS system were used to collect data from the participants. Results of the participants' scores acquired from the serious gaming module were compared with fNIRS measures on the initial and final training sessions. Kruskal Wallis test was run to determine any significant statistical difference between the groups and Mann-Whitney U test was utilized to obtain pairwise comparisons. BLS training scores of the participants acquired from VR based serious game's the learning management system and fNIRS measurements revealed decrease in use of resources from the PFC, but increase in behavioral performance. Importantly, brain-based measures can provide an additional quantitative metric for trainee's expertise development and can assist the medical simulation instructors.
