Trends in lumbar puncture utilization across a health system and in emergency department practice

Listen to this summary

The authors aimed to evaluate trends in lumbar puncture (LP) utilization and success rates within a tertiary care health system, particularly in the emergency department (ED). Their findings revealed a decline in LP volume in the ED, with a notable shift in indications towards idiopathic intracranial hypertension and a decrease in procedural success rates. Additionally, they identified that upright positioning during the procedure was associated with higher success rates compared to the traditional lateral decubitus position.
