Screening residents for infant lumbar puncture readiness with just-in-time simulation-based assessments.

Background: Determining when to entrust trainees to perform procedures is fundamental to patient safety and competency development.

Objective: To determine whether simulation-based readiness assessments of first year residents immediately prior to their first supervised infant lumbar punctures (LPs) are associated with success.

Methods: This prospective cohort study enrolled paediatric and other first year residents who perform LPs at 35 academic hospitals from 2012 to 2014. Within a standardised LP curriculum, a validated 4-point readiness assessment of first year residents was required immediately prior to their first supervised LP. A score ≥3 was required for residents to perform the LP. The proportion of successful LPs (<1000 red blood cells on first attempt) was determined. Process measures included success on any attempt, number of attempts, analgesia usage and use of the early stylet removal technique.

Results: We analysed 726 LPs reported from 1722 residents (42%). Of the 432 who underwent readiness assessments, 174 (40%, 95% CI 36% to 45%) successfully performed their first LP. Those who were not assessed succeeded in 103/294 (35%, 95% CI 30% to 41%) LPs. Assessed participants reported more frequent direct attending supervision of the LP (diff 16%; 95% CI 8% to 22%), greater use of topical analgesia (diff 6%; 95% CI 1% to 12%) and greater use of the early stylet removal technique (diff 11%; 95% CI 4% to 19%) but no difference in number of attempts or overall procedural success.

Conclusions: Simulation-based readiness assessments performed in a point-of-care fashion were associated with several desirable behaviours but were not associated with greater clinical success with LP.
