This study explores lumbar puncture operators stress associated with their performance of the procedure, across three experience levels: Experts, Intermediates, and Novices. The study will investigate the association of this potential stress to patient experienced stress and patient related outcomes of the lumbar puncture procedure.

Population

Physicians: Physicians working at departments with frequent performance of LP. Physicians should represent the three experience levels novices, intermediates and experts. Patients: All patients referred for a lumbar puncture with respect to inclusion and exclusion criteria.

Acute Mental Stress Among the Physician and Patient During Lumbar Puncture, and Its Impact on Performance and Patient Related Outcomes

Brief Summary

This study explores lumbar puncture operators stress associated with their performance of the<br /> procedure, across three experience levels: Experts, Intermediates, and Novices.<br /><br /> The study will investigate the association of this potential stress to patient experienced<br /> stress and patient related outcomes of the lumbar puncture procedure.

Detailed Description

The consequences of being in a state of Acute Mental Stress are reduced working memory,
decreased psychomotor performance, and impaired performance. Although some levels of
increased stress response might be beneficial, there seems to be an upper-limit when
performance is reduced.

According to the Cognitive Activation Theory of Stress (CATS), the stress sensation arises
when the requirements exceed the resources for a given task. For the LP procedure, a stress
sensation among novice residents might arise due to the combination of the LP being a complex
procedure depending on both technical as non-technical aspects combined with residents
uncertainties for procedural performance and a fear of doing harm.

Despite a growing recognition of stress among residents, the acute mental stress of residents
performing invasive procedures has been unacknowledged. Within neurology, internal medicine,
and emergency medicine a particular subject for this stress might pertain to residents' first
performance of the lumbar puncture.

However, for non-surgical invasive procedures as the LP, there is a lack of evidence for
measurements of AMS across experience levels and how this potential stress might influence
the performance and patient related outcomes.

Hence, the aim of this study is to explore stress levels across lumbar puncture experience
levels and how this potential stress might affect procedural performance and the patients'
experience of stress and outcomes of the procedure. Additionally, the study will explore a
potential correlation between patient stress and the risk of developing post-dural puncture
headache.
