Incoming residents’ knot-tying and suturing skills: Are medical school boot camps sufficient?

One-week radiology boot camp for pre-clerkship medical students: A novel format improving image interpretation and confidence

RATIONALE AND OBJECTIVES

To measure change in radiology knowledge, confidence in radiology skills, and perceptions pertaining to radiology following a one-week boot camp elective for undergraduate medical students.

MATERIALS AND METHODS

A five-day comprehensive radiology boot camp was developed including sessions on image interpretation, procedural skills, and appropriate image ordering. A multiple-choice quiz was administered before and after the elective, utilizing radiology questions from the validated AMSER STARS database. Additionally, a pre- and post-elective survey was administered assessing radiology career interest, confidence in radiology-based skills, and the potential ability of radiology-based skills to increase confidence in specialties other than radiology. Responses from the assessments were analysed using paired t-tests.

RESULTS

15 students enrolled in the course and 14 completed all assessments. The average score on the quiz increased from 50.1% to 66.0% (p<0.001). On the post-elective survey, the average student confidence score increased by more than one point on a six-point Likert scale in each of radiographic interpretation (p=0.004), ultrasound interpretation (p=0.0002), CT/MRI interpretation (p=0.02), general radiology knowledge including procedural skills (p=0.0001), and appropriate image ordering (p=0.004). Average student satisfaction with the elective was 8.1 out of 10.

CONCLUSION

A one-week radiology boot camp for pre-clerkship medical students improved radiology knowledge and confidence in radiology skills, showing potential for this format to meet the demand for increased radiology content in undergraduate training. Students indicated that confidence in radiology knowledge would increase confidence on non-radiology clerkship rotations, highlighting the importance of how a one-week radiology bootcamp can impact both future radiology and non-radiology clerkship experiences.

The development and evaluation of "Training the trainer" curriculum for surgical residents: Feasibility study

BACKGROUND

Over the last decades, there has been greater emphasis on enhancing teaching skills and concepts of Train-The-Trainer (TTT) have been widely adopted across surgical training programs. Current TTT curricula, however, mostly address teaching generic principles without specific guidance on how to teach technical skills among residents. The aim of this proof-of-concept study was to design a bespoke TTT curriculum for surgical technical skills and evaluate its impact.

MATERIAL AND METHODS

A bespoke TTT curriculum was developed to address key teaching surgical skills including a training framework, and performance enhancing feedback. The curriculum was delivered to 41 junior surgical residents in this feasibility study and focused on promoting a training framework including three domains; "set" involving pre-operative preparation, "dialogue" referring to teaching techniques and "closure" covering structured feedback. It was evaluated using Kirkpatrick's model: (i) course feedback; (ii) training quality assessment on a suturing simulated scenario using (a) Competency Assessment Tool (CAT) and a (b) Structured Training Trainer Assessment Report (STTAR) tool; (iii-iv) follow-up survey after one year.

RESULTS

The TTT curriculum was well-perceived, with a median score of 4/5 ("agree") across all components of evaluation forms. The simulated training scenario demonstrated a significant reduction in suturing errors following delivery of training (pre-TTT [4.25; IQR:4.42]; post-TTT [2.34; IQR:2.38], p-value = 0.014). Improvement in teaching was also noted and reflected in 'Set' (pre-TTT [3.50; IQR: 3.00] and post-TTT [5.00; IQR: 0.00], p-value = 0.019) and 'Closure' (pre-TTT [4.75; IQR: 1.88] and post-TTT [5.00; IQR: 0.00], p value = 0.007). 25% of participants contributed to the long-term survey highlighting that most practiced skills within 6 months of the curriculum with positive feedback from their learners.

CONCLUSION

This proof-of-concept study confirms the feasibility and acceptability of delivering a bespoke Train-The-Trainer curriculum to surgical residents. It provides a structured training framework that can enhance teaching technical skills.

Emerging simulation technologies in global craniofacial surgical training

The last few decades have seen an exponential growth in the development and adoption of novel technologies in medical and surgical training of residents globally. Simulation is an active and innovative teaching method, and can be achieved via physical or digital models. Simulation allows the learners to repeatedly practice without the risk of causing any error in an actual patient and enhance their surgical skills and efficiency. Simulation may also allow the clinical instructor to objectively test the ability of the trainee to carry out the clinical procedure competently and independently prior to trainee's completion of the program. This review aims to explore the role of emerging simulation technologies globally in craniofacial training of students and residents in improving their surgical knowledge and skills. These technologies include 3D printed biomodels, virtual and augmented reality, use of google glass, hololens and haptic feedback, surgical boot camps, serious games and escape games and how they can be implemented in low and middle income countries. Craniofacial surgical training methods will probably go through a sea change in the coming years, with the integration of these new technologies in the surgical curriculum, allowing learning in a safe environment with a virtual patient, through repeated exercise. In future, it may also be used as an assessment tool to perform any specific procedure, without putting the actual patient on risk. Although these new technologies are being enthusiastically welcomed by the young surgeons, they should only be used as an addition to the actual curriculum and not as a replacement to the conventional tools, as the mentor-mentee relationship can never be replaced by any technology.

In-person versus virtual suturing and knot-tying curricula: Skills training during the COVID-19 era

Background

The coronavirus disease 2019 restrictions on in-person simulation activities necessitated modifying the traditional boot camp skills curriculum for matriculating PGY1 general surgery residents to a virtual format. This study investigated the relative effectiveness of in-person versus virtual instruction on the development of suturing and knot-tying skills.

Methods

In all, 55 residents participated in a validated, proficiency-based, preinternship skills curriculum, 26 in 2019 and 29 in 2020. Both groups received an introduction to the curriculum, were given time for practice and offered one-on-one tutoring by faculty by request, and completed a filmed posttest. The 2019 class received in-person instruction during a boot camp at the end of June, while the 2020 class was provided with suture kits and received instruction via Zoom throughout June. The 2 groups were compared by post-test performance, date of task proficiency, and additional coaching required.

Results

In 2019, 5.7% of the posttest tasks were graded as proficient versus 87% in 2020. The 2020 class outperformed the 2019 class on every metric in every task (P < .001). In 2019, faculty spent 55.5 hours with residents in one-on-one remediation, resulting in proficiency in 64% of the tasks by November. In 2020, 18 hours of one-on-one remediation resulted in proficiency in 92% of the tasks by September.

Conclusion

Learners who received virtual instruction with access to materials at home gained proficiency in suturing and knot-tying skills earlier and with less coaching. These data demonstrate that the virtual curriculum is effective and an improvement on the previous in-person curriculum.

Simulation in surgical education

Simulation is becoming an important tool in surgical education. Surgical faculty have been forced to modify how they teach technical skills. Instead of a complete reliance on teaching in the operating room, a structured curriculum and dedicated time in the simulation center are being used in many centers. Some of the advantages of this approach include the ability to learn and practice new procedures in a safe and nurturing environment. The disadvantages include the significant cost of virtual reality simulators and the competition, between various training programs, to gain access to simulation.

Acquisition and retention of surgical skills taught during intern surgical boot camp

BACKGROUND

Surgical residencies have implemented boot-camps for early acquisition of basic technical skills for interns. However, educators worry that retention is poor. We hypothesized that a structured boot-camp curriculum would improve skills.

METHODS

Interns underwent eight boot-camp sessions at the beginning of residency. Interns completed pre-, post-boot-camp, and end-of-year skills assessments, as well as post-boot camp and end-of-year porcine procedure labs. Proficiency was measured on a 5-point scale and by completion time.

RESULTS

After boot-camp, interns improved all domains of knot-tying. Median time decreased for skin-closure (8.3 vs 9.9 min, p < 0.01), peg transfer (57 vs 87 s, p < 0.01), intracorporeal (178 vs 300 s, p < 0.01), and extracorporeal knot-tying (140 vs 259 s, p < 0.01). At the end-of-year assessment, interns exhibited retention of all skills and improved in knot-tying and central line skills. During the retention porcine lab, interns progressed basic but not complex skills.

CONCLUSIONS

An eight-week boot-camp effectively improved technical skills among surgery interns. Interns retained all skills and improved upon techniques frequently practiced during intern year.
