Objectives: Motor neuron disease (MND) is a neurodegenerative disorder leading to functional decline and death. Multidisciplinary MND clinics provide an integrated approach to management and facilitate discussion on advanced care directives (ACDs). The study objectives are to analyse (1) the prevalence of ACD in our MND clinic, (2) the relationship between ACD and patient demographics and (3) the relationship between ACD decision-making and variables such as NIV, PEG, hospital admissions and location of death.
Methods: Using clinic records, all patients who attended the MND clinic in Liverpool Hospital between November 2014 and November 2019 were analysed. Data include MND subtypes, symptom onset to time of diagnosis, time of diagnosis to death, location and reason of death. ACD prevalence, non-invasive ventilation (NIV) and percutaneous endoscopic gastrostomy (PEG) requirements were analysed.
Results: There were 78 patients; M:F=1:1. 44 (56%) patients were limb onset, 28 (36%) bulbar onset, 4 primary lateral sclerosis and 2 flail limb syndrome presentations. 27% patients completed ACDs, while 32% patients declined ACDs. Patients born in Australia or in a majority English-speaking country were more likely to complete ACDs compared to those born in a non-English-speaking country. There was no significant correlation between ACD completion and age, gender, MND subtype, symptom duration, NIV, PEG feeding, location of death.
Conclusion: One-quarter of patients completed ACDs. ACDs did not correlate with patient age, gender, MND subtype and symptom duration or decision-making regarding NIV, PEG feeding or location of death. Further studies are needed to address factors influencing patients' decisions regarding ACDs.
