How to minimize the risk for headache? A lumbar puncture practice questionnaire study

Area of Science:

• Neurology
• Medical Procedures

Background:

• The American Academy of Neurology (AAN) recommended atraumatic needles for lumbar puncture (LP) in 2005 to reduce post-LP headache.
• Adherence to these AAN guidelines among neurologists is not well-documented.

Purpose of the Study:

• To assess neurologists' current practices regarding diagnostic LP needle selection.
• To evaluate awareness and acceptance of AAN guidelines for LP.
• To review existing literature on LP practices.

Main Methods:

• An online questionnaire was distributed to neurologists performing diagnostic LPs.
• A literature review identified five relevant studies published between 1998 and 2015.
• Data on needle preference, guideline awareness, and reasons for non-adherence were collected.

Main Results:

• 41% of 284 respondents always used atraumatic needles, a higher rate than reported in previous studies (2-16%).
• Lack of needle availability was the primary reason (73%) for not using atraumatic needles.
• Less than half of respondents knew about the AAN guidelines, with agreement varying from 48-76%.

Conclusions:

• Atraumatic needle use in diagnostic LP has increased but is still suboptimal.
• Needle availability is a significant obstacle to guideline implementation.
• Increased awareness, training, and further research on atraumatic needle benefits are needed to improve practice.
