A nudge towards better lumbar puncture practice

Le résumé fourni par la source

BACKGROUND: Despite a body of evidence demonstrating reduced incidence of post-lumbar puncture headache associated with pencil-point (vs bevelled-edge) needles, their use remains variable in the UK. METHODS: A multimodal longitudinal intervention was performed over a 12-month period at a tertiary neurology referral centre. In addition to simulation training using pencil-point needles and an electronic documentation pro forma, a change in the default needles presented in clinical environments was performed. RESULTS: Prior to the intervention, pencil-point needle usage was minimal. Documentation significantly improved throughout the intervention period. Simulation training interventions only resulted in transient, moderate improvements in pencil-point needle usage. However, changing the default produced a marked increase in use that was sustained. No significant changes in operator success rate were found. CONCLUSIONS: In the context of wider literature on the power of default options in driving behavioural choices, changing defaults may be an effective, inexpensive and acceptable intervention to improve lumbar puncture practice.
