This year’s Annual Conference research talk was given by Dr Chris McDermott and focused on his research at the Sheffield Institute for Translational Neuroscience (SiTraN). His talk, adequately named ‘Improving the care and evidence base for symptomatic care’, was a very personal and informative talk to all that attended.
Dr McDermott gave a brief introduction about how he became a neurologist and got involved with MND research. He then talked about non-invasive ventilation (NIV) and how, through healthcare research, they have already gained evidence that NIV increases survival and improves the quality of life for people with MND. After this evidence was obtained, the technique gained National Institute of Health and Clinical Excellence (NICE) approval and NIV is now a standard treatment for people with MND who experience respiratory weakness.
Dr McDermott also mentioned how a ‘cough assist machine’ can be used to help patients cough and get rid of secretions and dirt. Information from the literature suggested a reduction of hospital admissions, and infections, in the year following the use of a cough assist machine for other diseases. The results from Dr McDermott’s MND Association funded study, looking at a cough assist machine for people with MND are yet to be analysed.
The rest of Dr McDermott’s talk focused on his current diaphragm pacing trial (known as DiPALS) being part-funded by the MND Association.
Dr McDermott explained that diaphragm pacing is designed so that people with MND do not have to be on long-term ventilation units, as the remote unit can be carried around when in use. Diaphragm pacing is similar to that of a ‘pace maker’, but instead of the heart it stimulates the diaphragm using an electrical current.
A video was shown of how the instrument’s electrodes are placed onto the diaphragm muscle during a 30 minute key-hole surgery procedure. The pacing unit is then controlled by an external remote at present, but if trials are successful an internal unit could be developed.
Dr McDermott stressed that the mechanisms in which diaphragm pacing acts is not known at present but suggested that it may cause stronger contractions or restore co-ordinated breathing.
An American study of 106 people with MND who had advanced respiratory problems previously found that 81% of trial participants were still alive after one year. Dr McDermott went on to explain that this study had no control group to test whether the diaphragm pacing unit improves life over and above that of current standards of care. However, the American study did find diaphragm pacing to be safe.
The DiPALS study in the UK has been recruiting patients with MND since November 2011 and compares NIV alone (control group) and NIV plus diaphragm pacing. Dr McDermott’s study aims to see if there is a difference in survival between the two groups, whether there is an improvement to quality of life, whether it is less intrusive, and whether the treatment is cost-effective. If diaphragm pacing does show a difference, then this could lead to NICE approval and become standard NHS-provided care in the UK. Dr McDermott went on to say that even if the study is found not to be a viable treatment the trial has already importantly shown that people with MND can have a general anaesthetic.
As the study is ongoing the final results are not available. Results are due in autumn 2014.
Overall, it was great to have an update into Dr McDermott’s research which stimulated an abundance of questions from all those that attended, leaving delegates with a real insight into some of the healthcare research funded by the Association.
