Collaboration in the presence of cerebral edema: The complications of steroids.
BACKGROUND
Brain tumor patients often present with neurological changes in the presence of cerebral edema. High-dose dexamethasone is often required for symptom management in brain tumor patients. There are limitations in the foundational research that support the recommendations for appropriate prescribing of dexamethasone. Understanding these limitations can help prescribers and care teams collaborate to better manage this unique patient population as well as identify areas for further research.


METHODS
Evidence-based clinical practice guidelines for the management of adult brain tumor patients were reviewed from several certifying organizations. A complex database search and literature review was completed regarding relevant evidence used within these guidelines and for any supporting literature. The search was limited to MEDLINE, Cumulative Index to Nursing and Allied Health, Cochrane Library, and the National Guideline Clearinghouse using keywords. Each selected evidence-based guideline underwent appraisal using the Johns Hopkins Evidence-based Practice Model.


RESULTS
All clinical practice guidelines identified recommendations for appropriate dosing and tapering of dexamethasone. The management of steroid-induced side effects was addressed in two of the reviewed guidelines. Only one guideline identified specific nursing interventions for monitoring steroid-related side effects. No guideline addressed interval timing of provider or nursing-based interventions as well as the role of collaboration between provider and nurse in monitoring for steroid toxicities.


CONCLUSIONS
More high-quality, well-controlled studies are needed around dexamethasone dosing for the management of cerebral edema. Clinical practice guidelines need to encompass both the prescriber and nursing-based interventions. Collaboration between disciplines is a necessity when monitoring and managing steroid-induced toxicities in brain tumor patients. Future evidence-based guidelines need recommendations for appropriate interval screening tests and quantifiable tools needed to aid in monitoring steroid-induced complications.
