Input: No randomised controlled trials or controlled clinical trials were identified for the original review or this update.  We summarised the results of five observational studies (including one with two reports) in the Discussion section of this review. In the absence of randomised controlled trials or controlled clinical trials, the 'best' evidence to date is based on three ‘low’ and two ‘very low quality’ observational studies. These suggest 'very low quality evidence' for an advantage for mental health domains (only) of quality of life without increasing healthcare costs, and 'low level quality' evidence for reduced hospitalisation for MDC in low-intensity outpatient settings; and 'very low quality' evidence for improved disability in high-intensity settings. The evidence for survival is conflicting. These conclusions are tentative and the gap in current research should not be interpreted as proof that MDC is ineffective. Further research is needed into appropriate study designs; outcome measurement; caregiver needs; and the evaluation of optimal settings, type, intensity or frequency and cost-effectiveness of MDC in the MND population. Future research should focus on observational designs to assess care and outcomes in 'real-life' settings. The interface between neurology, rehabilitation and palliative care should be explored to provide long-term support for MND.
Output:

This review did not find any high quality randomised controlled trials that examined the effectiveness of such multidisciplinary care, either when originally published in 2009 or for the update in 2011. The evidence from low quality studies suggests that such care may improve some aspects of quality of life, reduce the frequency of hospitalisation and hospital length of stay and improve disability in persons with ALS or MND. The evidence for multidisciplinary care on survival is conflicting. The gap in current research should not be interpreted as proof that multidisciplinary care is ineffective. Further research into types of appropriate studies, caregiver needs and various aspects of multidisciplinary care in the MND population is needed.
