Lost opportunity cost of surgical training in the Australian private sector

Application of 3D Printing in Cleft Lip and Palate Repair

This manuscript reviews the transformative impact of 3-dimensional (3D) printing technologies in the treatment and management of cleft lip and palate (CLP), highlighting its application across presurgical planning, surgical training, implantable scaffolds, and postoperative care. By integrating patient-specific data through computer-aided design and manufacturing, 3D printing offers tailored solutions that improve surgical outcomes, reduce operation times, and enhance patient care. The review synthesizes current research findings, technical advancements, and clinical applications, illustrating the potential of 3D printing to revolutionize CLP treatment. Further, it discusses the future directions of combining 3D printing with other innovative technologies like artificial intelligence, 4D printing, and in situ bioprinting for more comprehensive care strategies. This paper underscores the necessity for multidisciplinary collaboration and further research to overcome existing challenges and fully utilize the capabilities of 3D printing in CLP repair.

Cleft lip and palate surgery simulator: Open source simulation model

Objective

Cleft lip and palate is the most common craniofacial birth anomaly and requires surgery in the first year of life. However, craniofacial surgery training opportunities are limited. The aim of this study was to present and evaluate an open-source cleft lip and palate hybrid (casting and three-dimensional (3D) printing) simulation model which can be replicated at low cost to facilitate the teaching and training of cleft surgery anatomy and techniques.

Design

The soft tissue component of the cleft surgery training model was casted using a 3D printed 5-component mold and silicone. The bony structure was designed to simulate the facial anatomy and to hold the silicone soft tissue.

Setting

Two groups, one group of trainees and one group of expert surgeons, at University Hospital Basel in Switzerland and Pontifical Catholic University of Chile in Santiago, Chile, tested the cleft lip and palate simulation model. Participants completed a Likert-based face and content validity questionnaire to assess the realism of the model and its usefulness in surgical training.

Results

More than 70 % of the participants agreed that the model accurately simulated human tissues found in patients with unilateral cleft lip and palate. Over 60 % of the participants also agreed that the model realistically replicated surgical procedures. In addition, 80-90 % of the participants found the model to be a useful and appropriate tool for teaching the anatomy and surgical techniques involved in performing unilateral cleft lip and palate repair.

Conclusion

This open-source protocol provides a cost-effective solution for surgeons to introduce the cleft morphology and surgical techniques to trainees on a regular basis. It addresses the current financial barrier that limits access to commercially available models during the early stages of surgeon training prior to specialization in the field.

Process-oriented metrics to provide feedback and assess the performance of students who are learning surgical procedures: The percutaneous dilatational tracheostomy case

PURPOSE

Assessing competency in surgical procedures is key for instructors to distinguish whether a resident is qualified to perform them on patients. Currently, assessment techniques do not always focus on providing feedback about the order in which the activities need to be performed. In this research, using a Process Mining approach, process-oriented metrics are proposed to assess the training of residents in a Percutaneous Dilatational Tracheostomy (PDT) simulator, identifying the critical points in the execution of the surgical process.

MATERIALS AND METHODS

A reference process model of the procedure was defined, and video recordings of student training sessions in the PDT simulator were collected and tagged to generate event logs. Three process-oriented metrics were proposed to assess the performance of the residents in training.

RESULTS

Although the students were proficient in classic metrics, they did not reach the optimum in process-oriented metrics. Only in 25% of the stages the optimum was achieved in the last session. In these stages, the four more challenging activities were also identified, which account for 32% of the process-oriented metrics errors.

CONCLUSIONS

Process-oriented metrics offer a new perspective on surgical procedures performance, providing a more granular perspective, which enables a more specific and actionable feedback for both students and instructors.

[Survey on training in orthopedics/trauma surgery : Is Germany ready for a competence-based training?]

BACKGROUND AND OBJECTIVE

A high-quality advanced training is a key factor for good and safe patient treatment. Germany is currently revising the advanced training curricula and logbooks aiming to change the training into a competence-based training. The aim of this study was to analyze the day to day reality of orthopedic and trauma surgery advanced training in Germany based on the elements of the advanced training.

METHODS

In March 2020 an online survey on advanced training was carried out with 44 questions on the topics of advanced training curriculum, logbook, educational resources, evaluation, authorized trainer and distribution of working time .

RESULTS

A total of 237 persons completed the survey, of which 208 fulfilled the inclusion criteria. The respondents perceived a lack of clear standards in the advanced training curriculum and 25% did not receive structured learning resources in the form of simulations or courses. Mandatory annual process interviews were performed in only 58%. Most respondents valued the expertise of the trainers in orthopedic and trauma surgery, whereas they rated their competence in supervision and giving feedback as below average. Administrative work consumed 220 min of the daily working time and on average 60min remained per day for respondents to learn operative skills.

CONCLUSION

The survey revealed inconsistencies in the current advanced training curriculum and a lack of supervision and evaluation. The implementation of competence-based advanced training should therefore not only focus on a change of the curriculum but also on implementing competence-based training at all levels of training (learning resources, training, evaluation).

What it takes to become an orthopaedic surgeon: A comparison of orthopaedic surgical training programmes in 10 countries focusing on structure and fellowship requirements

BACKGROUND

The quality of surgical training has been highlighted as one of the most important patient safety issues in the future. Training surgeons and supporting them to do their best should be considered integral in providing optimum and safe care for the individual patient and the best possible return on investment in training medical professionals. In 2011, an international consensus statement defined fundamental principles for surgical training.

PURPOSE

This study examines orthopaedic surgical training to explore the similarities and differences in the requirements for trainees to obtain board certification in ten countries.

METHODS

Countries of the Commonwealth Health Care Comparison: Canada, the United Kingdom, the United States of America, Australia, New Zealand, Germany, France, the Netherlands, Norway and Switzerland were chosen to be compared. The relevant information was extracted from official information from authorities and administrative bodies.

RESULTS

The study revealed significant differences in duration, organisation and assessment of training. So-called "competency-based" training is not featured in every country, and the manner of its implementation is variable. In particular, the numbers in surgical cases required to be accredited varies by country ranging from 1260 (UK) to 340 (Norway).

CONCLUSION

Despite the recommendation in 2011 for some degree of uniformity across surgical training in industrialised countries, evidence suggests wide variation in the training programmes which is likely to be a concern in both quality of training as well as present and future patient safety.

3D Printed Models of Cleft Palate Pathology for Surgical Education

To explore the potential viability and limitations of 3D printed models of children with cleft palate deformity.

BACKGROUND

The advantages of 3D printed replicas of normal anatomical specimens have previously been described. The creation of 3D prints displaying patient-specific anatomical pathology for surgical planning and interventions is an emerging field. Here we explored the possibility of taking rare pediatric radiographic data sets to create 3D prints for surgical education.

METHODS

Magnetic resonance imaging data of 2 children (8 and 14 months) were segmented, colored, and anonymized, and stereolothographic files were prepared for 3D printing on either multicolor plastic or powder 3D printers and multimaterial 3D printers.

RESULTS

Two models were deemed of sufficient quality and anatomical accuracy to print unamended. One data set was further manipulated digitally to artificially extend the length of the cleft. Thus, 3 models were printed: 1 incomplete soft-palate deformity, 1 incomplete anterior palate deformity, and 1 complete cleft palate. All had cleft lip deformity. The single-material 3D prints are of sufficient quality to accurately identify the nature and extent of the deformities. Multimaterial prints were subsequently created, which could be valuable in surgical training.

CONCLUSION

Improvements in the quality and resolution of radiographic imaging combined with the advent of multicolor multiproperty printer technology will make it feasible in the near future to print 3D replicas in materials that mimic the mechanical properties and color of live human tissue making them potentially suitable for surgical training.
