Evaluation of a novel laparoscopic simulation laboratory curriculum

Virtual simulations for neonatal education

Virtual simulation (VS) education involves the use of virtual reality, augmented reality, mixed reality and screen-based platforms, collectively referred to as extended reality, to provide education and assessment. This novel simulation modality supports experiential learning and increases access to practice opportunities, supplementing manikin-based simulation. VS has been used successfully for neonatal resuscitation training in high and low resource settings. Virtual simulators can be used to objectively assess learner performance in neonatal resuscitation knowledge and skills. When implementing VS for neonatal resuscitation training, key considerations include matching learning objectives with suitable technology, pre-session preparation, supporting learners, and debriefing. Additional research is needed to evaluate the impact of VS applications on clinical practice and patient outcomes.

How We Evaluate Postgraduate Medical E-Learning: Systematic Review

BACKGROUND

Electronic learning (e-learning) in postgraduate medical education has seen a rapid evolution; however, we tend to evaluate it only on its primary outcome or learning aim, whereas its effectiveness also depends on its instructional design. We believe it is important to have an overview of all the methods currently used to evaluate e-learning design so that the preferred method may be identified and the next steps needed to continue to evaluate postgraduate medical e-learning may be outlined.

OBJECTIVE

This study aimed to identify and compare the outcomes and methods used to evaluate postgraduate medical e-learning.

METHODS

We performed a systematic literature review using the Web of Science, PubMed, Education Resources Information Center, and Cumulative Index of Nursing and Allied Health Literature databases. Studies that used postgraduates as participants and evaluated any form of e-learning were included. Studies without any evaluation outcome (eg, just a description of e-learning) were excluded.

RESULTS

The initial search identified 5973 articles, of which we used 418 for our analysis. The types of studies were trials, prospective cohorts, case reports, and reviews. The primary outcomes of the included studies were knowledge, skills, and attitude. A total of 12 instruments were used to evaluate a specific primary outcome, such as laparoscopic skills or stress related to training. The secondary outcomes mainly evaluated satisfaction, motivation, efficiency, and usefulness. We found 13 e-learning design methods across 19 studies (4% 19/418). The methods evaluated usability, motivational characteristics, and the use of learning styles or were based on instructional design theories, such as Gagne's instructional design, the Heidelberg inventory, Kern's curriculum development steps, and a scale based on the cognitive load theory. Finally, 2 instruments attempted to evaluate several aspects of a design, based on the experience of creating e-learning.

CONCLUSIONS

Evaluating the effect of e-learning design is complicated. Given the diversity of e-learning methods, there are many ways to carry out such an evaluation, and probably, many ways to do so correctly. However, the current literature shows us that we have yet to reach any form of consensus about which indicators to evaluate. There is a great need for an evaluation tool that is properly constructed, validated, and tested. This could be a more homogeneous way to compare the effects of e-learning and for the authors of e-learning to continue to improve their product.

Development of a Model for the Acquisition and Assessment of Advanced Laparoscopic Suturing Skills Using an Automated Device

BACKGROUND

Needs assessment identified a gap regarding laparoscopic suturing skills targeted in simulation. This study collected validity evidence for an advanced laparoscopic suturing task using an Endo Stitch^TM device.

METHODS

Experienced (ES) and novice surgeons (NS) performed continuous suturing after watching an instructional video. Scores were based on time and accuracy, and Global Operative Assessment of Laparoscopic Surgery. Data are shown as medians [25th-75th percentiles] (ES vs NS). Interrater reliability was calculated using intraclass correlation coefficients (confidence interval).

RESULTS

Seventeen participants were enrolled. Experienced surgeons had significantly greater task (980 [964-999] vs 666 [391-711], P = .0035) and Global Operative Assessment of Laparoscopic Surgery scores (25 [24-25] vs 14 [12-17], P = .0029). Interrater reliability for time and accuracy were 1.0 and 0.9 (0.74-0.96), respectively. All experienced surgeons agreed that the task was relevant to practice.

CONCLUSION

This study provides validity evidence for the task as a measure of laparoscopic suturing skill using an automated suturing device. It could help trainees acquire the skills they need to better prepare for clinical learning.

Evaluation of surgical training in the era of simulation

AIM

To assess where we currently stand in relation to simulator-based training within modern surgical training curricula.

METHODS

A systematic literature search was performed in PubMed database using keywords "simulation", "skills assessment" and "surgery". The studies retrieved were examined according to the inclusion and exclusion criteria. Time period reviewed was 2000 to 2013. The methodology of skills assessment was examined.

RESULTS

Five hundred and fifteen articles focussed upon simulator based skills assessment. Fifty-two articles were identified that dealt with technical skills assessment in general surgery. Five articles assessed open skills, 37 assessed laparoscopic skills, 4 articles assessed both open and laparoscopic skills and 6 assessed endoscopic skills. Only 12 articles were found to be integrating simulators in the surgical training curricula. Observational assessment tools, in the form of Objective Structured Assessment of Technical Skills (OSATS) dominated the literature.

CONCLUSION

Observational tools such as OSATS remain the top assessment instrument in surgical training especially in open technical skills. Unlike the aviation industry, simulation based assessment has only now begun to cross the threshold of incorporation into mainstream skills training. Over the next decade we expect the promise of simulator-based training to finally take flight and begin an exciting voyage of discovery for surgical trainees.

Haemothorax following bullectomy caused by a sharp edge of the Endoloop

A 22-year old man presented with a massive haemothorax 25 days after bullectomy for a spontaneous pneumothorax. Thoracoscopic surgery revealed ongoing bleeding from the chest wall caused by a sharp edge of the Endoloop Ligature (Ethicon Endo-Surgery) used to resect the remaining small part of the lung at the earlier staple bullectomy. The point where bleeding was occurring was clipped and covered using a collagen patch coated with human fibrinogen and thrombin. The protruding sharp edge of the Endoloop was excised together with the surrounding lung tissue, using a stapler. Although prevention of this type of complication is difficult, awareness of the potential problem may help in managing such extremely rare events.
