Reporting on Neurological Decline as Identified by Hourly Neuroassessments

BACKGROUND: Hourly neurological examinations (neuro exam) have been widely used to monitor for a decline in neurological status, allowing for timely intervention. There are, however, limited data behind this common practice. The objective of this study was to identify how frequently neurological decline occurred across various diagnoses and whether that decline (1) was identified by a scheduled neurocheck and (2) altered management. METHODS: A cross-sectional survey was performed in a neurological intensive care unit at a tertiary care academic medical center. Clinical neuroscience nurses caring for patients with hourly neurological assessments completed a brief survey at 12-hour shift completion. RESULTS: Data were collected from 212 nurse's shifts. Neurological changes were identified by nurses in 14% (n = 30) of shifts. The neurological change was identified during a scheduled neurocheck 67% of the time, with the detection of changes more likely to occur during a scheduled neuro exam than at other times (P < .05). There was no change to the care plan in 55% of the cases of neurological decline. Patients with subarachnoid hemorrhage were more likely to have a decline detected. CONCLUSION: Findings suggest that many patients undergo hourly neurological exams without ever identifying a neurological deterioration. In many instances of neurodeterioration, there was no change to the treatment plan pursued. Primary diagnoses and neurological changes may not be entirely independent, and therefore, hourly neuro exams may have greater yield in some diagnoses than others. Replication is warranted with a larger sample to evaluate the risks and benefits of neuroassessments.
