Developing a Mobile App for Neuroscience Nurses.

In this month's Magnet® Perspectives column, the recipient of the 2016 Magnet Nurse of the Year® Award for New Knowledge, Innovations, and Improvements shares her journey to develop and disseminate a mobile application for nurses who care for neurological patients. "Neuroscience nurse" puts the latest, evidence-based information at the fingertips of nurses at the bedside in an effort to increase confidence when caring for patients with stroke, traumatic brain injury, and other neurological impairments.Nurse practitioner Christi DeLemos explains where she got the idea and how she went about implementing it. She also discusses the ways in which the Magnet® environment at University of California (UC) Davis Medical Center encouraged and supported her. Since neurological nurse was released in 2015, more than 3000 users in 19 countries have downloaded it. The app's success led to the production of a teaching video to help nurses perform a neurological examination. In addition to her role at UC Davis Medical Center, DeLemos is president of the World Federation of Neuroscience Nurses.

Aneurysmal subarachnoid hemorrhage survivors show long-term deficits in spatial reference memory in a pilot study of a virtual water maze paradigm.

BACKGROUND: Limited data exists on the long-term effects of aneurysmal subarachnoid hemorrhage (SAH) on spatial memory. Herein, we used a computerized virtual water maze to evaluate the feasibility of spatial memory testing in pilot cohort of ten patients who survived previous SAH. METHODS: Ten SAH survivors (5.8 ± 5.1 years after initial hemorrhage) and 7 age-matched controls underwent testing in a virtual water maze computer program. Additional subgroup analyses were performed to evaluate spatial reference memory correlation for ventricular size on admission, placement of an external ventricular drain and placement of a shunt. RESULTS: With respect to the spatial memory acquisition phase, there was no significant difference of pathway length traveled to reach the platform between SAH survivors and control subjects. During the probe trial, control subjects spent significantly longer time in target quadrants compared to SAH survivors (F(3, 24) = 10.32, p = 0.0001; Target vs. Right: Mean percent difference 0.16 [0-0.32], p = 0.045; Target vs. Across: Mean percent difference 0.35 [0.19-0.51], p < 0.0001; Target vs. Left: Mean percent difference 0.21 [0.05-0.37], p = 0.0094). Furthermore, patients who initially presented with smaller ventricles performed worse that those patients who had ventriculomegaly and/or required surgical management of hydrocephalus. CONCLUSIONS: Our data demonstrate that SAH survivors have persistent spatial reference memory deficits years after the hemorrhage. Hydrocephalus at presentation and external ventricular drainage were not found to be associated with poor spatial memory outcomes in this pilot cohort. Therefore, other causes such as global cerebral edema or magnitude of initial ICP spike, need to be considered to be examined as root cause as well in subsequent studies. The protocol described in this manuscript is able to demonstrate a spatial reference memory deficit and can be used to study risk factors for spatial memory impairment on a larger scale.
