The document discusses evaluating the effectiveness of a Train-the-Trainer (TTT) module on supervisors' ability to accurately rate simulated lumbar punctures on infants using a 4-point scale. It describes showing the TTT module to one group of supervisors (intervention group) and not showing it to another group (control group). Both groups will then rate 4 simulated lumbar puncture videos of varying skill levels. The goal is to see if the TTT improved the intervention group's scoring accuracy compared to the control group without the training.

1. The Effect of Train-the-Trainer
Modules on evaluating Simulated
Lumbar Punctures

2. Background
• The former POISE Network used Train-the-
Trainer (TTT) Modules for supervisors for the
Infant Lumbar Puncture (LP) study
• TTT show how infant LPs should be rated on a
4-point Global Assessment Scale (GAS)
• It is unknown if the TTT truly affected the
supervisors’ ability to rate simulated LPs

4. PICO Question
• Population
– In senior residents, fellows, and attendings who have
supervisory exposure to infant LPs,
• Intervention
– Does the completion of a TTT Module
• Comparison
– Compared with no such use
• Outcome
– Improve the Scoring Accuracy when rating 4
standardized simulated LPs on video?

5. Approach
• Record 4 simulated LPs used in the Validation
study reflecting 4 levels of expertise: Novice,
Beginner, Competent, Proficient
• Randomize scenarios on SurveyMonkey
• Approach POISE Network trainers as the
Intervention Group and ask to rate LP videos
• Approach EXPRESS Network trainers as the
Control Group without exposure to the TTT

6. 3 Questions
• Should there be 3 groups: TTT, LP Study
exposure without TTT, and Control?
• What is the optimal scoring method?
• How do we prevent inoculation when
testing a TTT v2.0 Module?
