Does a mixed training course on the Oxford unicompartmental knee arthroplasty improve non-technical skills of orthopaedic surgeons?

Consensus statement on unicompartmental knee replacement: A collaboration between BASK and EKS

BACKGROUND

The aim of this study was to deliver consensus recommendations for the clinical practice of unicompartmental knee arthroplasty (UKA).

METHODS

Members of the British Association for Surgery of the Knee (BASK) and European Knee Society (EKS) were invited to attend a joint meeting in London, UK (December 2019). A formal consensus process was undertaken at the meeting incorporating a multiple round Delphi exercise, with group discussion of areas of agreement and disagreement between rounds. Eighty delegates attended the meeting and five consensus statements were considered and revised, with a threshold level of 80% agreement required as the definition consensus.

RESULTS

Five consensus statements with accompanying supporting evidence and text were agreed following two rounds of the process: (1) UKA should be offered as a successful alternative to TKA in patients undergoing arthroplasty who meet agreed indications; (2) When consenting a patient for UKA, information including the benefits and risks that are specific to UKA, should be tailored to and discussed with the individual patient; (3) Evidence suggests that surgeons should avoid low-volume use of UKA to optimise outcomes for their patients; (4) Surgeons should use the contemporary evidence-based indications and contraindications for medial UKA; (5) Knee arthroplasty surgeons should have exposure to and training in UKA.

CONCLUSIONS

The agreed joint BASK-EKS consensus statements on UKA practice are recommended as the contemporary basis of optimal care for these patients and should inform future training and service developments.

Training Tools for Nontechnical Skills for Surgeons-A Systematic Review

OBJECTIVE

Development of nontechnical skills for surgeons has been recognized as an important factor in surgical care. Training tools for this specific domain are being created and validated to maximize the surgeon's nontechnical ability. This systematic review aims to outline, address, and recommend these training tools.

DESIGN

A full and comprehensive literature search, using a systematic format, was performed on ScienceDirect and PubMed, with data extraction occurring in line with specified inclusion criteria.

SETTING

Systematic review was performed fully at King's College London.

RESULTS

A total of 84 heterogeneous articles were used in this review. Further, 23 training tools including scoring systems, training programs, and mixtures of the two for a range of specialities were identified in the literature. Most can be applied to surgery overall, although some tools target specific specialities (such as neurosurgery). Interrater reliability, construct, content, and face validation statuses were variable according to the specific tool in question.

CONCLUSIONS

Study results pertaining to nontechnical skill training tools have thus far been universally positive, but further studies are required for those more recently developed and less extensively used tools. Recommendations can be made for individual training tools based on their level of validation and for their target audience. Based on the number of studies performed and their status of validity, NOTSS and Oxford NOTECHS II can be considered the gold standard for individual- and team-based nontechnical skills training, respectively, especially when used in conjunction with a training program.

Randomized clinical trial to evaluate mental practice in enhancing advanced laparoscopic surgical performance

BACKGROUND

Mental practice, the cognitive rehearsal of a task without physical movement, is known to enhance performance in sports and music. Investigation of this technique in surgery has been limited to basic operations. The purpose of this study was to develop mental practice scripts, and to assess their effect on advanced laparoscopic skills and surgeon stress levels in a crisis scenario.

METHODS

Twenty senior surgical trainees were randomized to either conventional training or mental practice groups, the latter being trained by an expert performance psychologist. Participants' skills were assessed while performing a porcine laparoscopic jejunojejunostomy as part of a crisis scenario in a simulated operating room, using the Objective Structured Assessment of Technical Skill (OSATS) and bariatric OSATS (BOSATS) instruments. Objective and subjective stress parameters were measured, as well as non-technical skills using the Non-Technical Skills for Surgeons rating tool.

RESULTS

An improvement in OSATS (P = 0.003) and BOSATS (P = 0.003) scores was seen in the mental practice group compared with the conventional training group. Seven of ten trainees improved their technical performance during the crisis scenario, whereas four of the ten conventionally trained participants deteriorated. Mental imagery ability improved significantly following mental practice training (P = 0.011), but not in the conventional group (P = 0.083). No differences in objective or subjective stress levels or non-technical skills were evident.

CONCLUSION

Mental practice improves technical performance for advanced laparoscopic tasks in the simulated operating room, and allows trainees to maintain or improve their performance despite added stress.
