Hydrocephalus Clinical Trial
Official title:
Investigating the Efficacy of Simulation Curricula in Neurosurgical Education
This study aims to investigate the efficacy of simulation in neurosurgical training.
This study aims to investigate the efficacy of simulation in neurosurgical training. This
will be assessed using accuracy and speed tests in the placement of external ventricle drain
catheters (EVDs). EVD placement is a relatively simple neurosurgical procedure aimed at
inexperienced young trainees.
This study has two arms. The recruits are inexperienced trainees and/or interns and students
who have never performed EVD placements before. The recruits are randomly assigned (using
computer-based randomisation) to either Arm A or Arm B.
Recruits to Arm A undergo simulation training (computer simulation of the procedure,
followed by simulation on a dead animal model), after which the recruits will attempt to
perform an EVD procedure on their own, on a 3D-printed skull model that we designed.
Recruits to Arm B will witness an EVD placement as performed by an experienced surgeon,
after the recruits will attempt to perform an EVD procedure on their own, using the
aforementioned 3D-printed skull model. This mimics the ''see one, do one'' paradigm
prevalent in surgical training.
The efficacy of the simulation training will be assessed using the following criteria:
i. Accuracy test:
The accuracy of the catheter placement is assessed in both arms and compared to investigate
whether there is a difference in the accuracy of the catheter placement in both arms.
ii. Speed test:
The speed of catheter placement is assessed in both arms and compared to investigate whether
there is a difference in the speed of the catheter placement in both arms.
iii. Subjective surveys
The researchers will gauge the extent of the trainees' confidence in their surgical skills
and their satisfaction with their training before and after completion of the simulation
training using a questionnaire to be designed for this purpose. The trainees will assess
their own familiarity with and confidence in the procedure using a scale from 0 ("not
familiar with the procedure", "I have no confidence in being able to perform this procedure
independently") to 10 ("I am an expert at this procedure", "I am able to perform this
procedure independently with complete confidence"). This data will be collected and input
into a statistical software (Statistical Lab v. 3, CeDiS) to analyse the difference (if any)
in the trainees' familiarity with the procedures and their confidence in being able to
perform them in both arms.
