Abstract 4114994: Nursing Management Practice Variations related to Externalized Ventricular and Lumbar Drains

Introduction/Background: Nursing management of neurologic patients may include placement of externalized ventricular drains (EVDs) or lumbar drains (LDs) to monitor/drain cerebrospinal fluid (CSF), but knowledge and practice related to EVD management varies widely, despite a high potential for life-threatening complications. Limited data exists relative to the relationship between intracranial pressure (ICP) and CSF drainage. These gaps may undermine patient safety. Research Question: What are the nursing practices and perspectives regarding management of EVDs and LDs? Methods/Approach: A 16-question multiple-choice/text entry survey was distributed electronically to nurses and advanced practice nurses who were members of the American Association of Neuroscience Nurses. Data analysis included chi-square test for multiple choice responses, and qualitative data was analyzed using a six-step thematic analysis and an inductive approach. Results/Data: Of 219 participants, 42.8% reported roles as Neuroscience ICU nurses, and 39.2% managed an EVD at least 75% of the time. Neuro ICU nurses were most likely to have a patient with an EVD ( p =.002). Approximately 63% of respondents reported consulting with colleagues about EVDs nearly every time they cared for a patient with an EVD. Nurses reported a very high care burden, including re-leveling the transducer 4 or more times per shift (n=76), and re-zeroing every 8 hours (n=72) to assure accurate calibration. Of these 82.2% reported that they re-zeroed the EVD more often to obtain an accurate reading. Approximately 25% reported accidental over-drainage, some with negative outcomes. Many (79.3%) reported caring for patients with LDs, 47.4% to diagnose normal pressure hydrocephalus. The nursing care workload was described as 30-120 minutes each shift. Conclusion: A wide heterogeneity of nursing practices was revealed in EVD and LD management. No standardized nursing care practices have been adopted by nurses for the management of CSF. The complications of these practice variations have been shown to result in untoward patient outcomes. Increased patient morbidity and mortality are linked to catheter infection and over/under drainage of CSF and may be directly related nursing practice. This reveals critical need for improved, standardized care nursing practices in the management of EVDs and LDs, and an empiric understanding of the relationship between intracranial pressure and the volume and rate of CSF drainage.
