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.
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.
