Controlled rehabilitative and supportive care intervention trials in patients with high-grade gliomas and their caregivers: A systematic review

Abstract

Background Patients diagnosed with highgrade gliomas experience a varying and complex symptom burden, and face a high mortality rate. As a consequence, patients with high-grade gliomas and their caregivers have imminent and changing rehabilitative and supportive care needs. Objectives To give a detailed overview of nonpharmacological rehabilitative and supportive care interventions for patients with high-grade gliomas and/or their caregivers, and provide an appraisal of the methodological quality of these studies. Method PubMed, Cumulative Index of Nursing and Allied Health Literature and Embase were searched for literature published from 1995 to May 2013. Data from eight studies were reviewed for substantive methods and results. Methodological quality was described and assessed using the scoring system for appraising mixed methods research and concomitantly appraising qualitative, quantitative and mixed methods primary studies in mixed study reviews. Results The search yielded 914 unique publications, of which 9 were classified eligible for this review. There is preliminary evidence that cognitive group therapy improves memory skills in patients with high-grade gliomas, early physical training improves functional outcome and massage therapy reduces stress. Patients and caregivers found that telephone follow-up and a specialist nurse function was an effective and useful way to achieve information and support. Finally, psycho-education increased feelings of mastery among caregivers. Conclusions As evidence is beginning to emerge, there is a need for well-designed longitudinal and randomised controlled trials of non-pharmacological interventions in high-grade glioma patients and their caregivers in order to develop clinical guidelines for supportive and rehabilitative approaches in this unique population.
