Parkinson’s disease: symptoms and medications at the end of life

Abstract

ObjectivesPeople with Parkinson’s disease (PwP) have a high palliative symptom burden throughout their disease course, equivalent to advanced malignancy. We aim to establish trends in symptom frequency and prescribing in the 72 hours prior to death for PwP.MethodsRetrospective case note review of PwP who died between February 2019 and September 2020.Results51 patients were included. 60.78% of patients (n=31) had agitation and 58.82% (n=30) had pain in the final 72 hours. Patients with cognitive impairment were 4.67 times more likely to experience agitation (p=0.035) compared with those without, with higher total midazolam doses (29.18 mg vs 11.4 mg, p=0.21). Terminal motor symptoms were recorded in three patients. 28.57% of patients received the recommended dose of rotigotine for dopaminergic therapy.ConclusionsPwP have a significant symptom burden at the end of life (EOL) with levels of terminal agitation at the higher end of those expected in the general population. There was a trend towards higher doses of sedation, rather than analgesia, in people with coexistent cognitive impairment.Terminal stiffness, despite being seldom documented in the literature, is an important although infrequent symptom.Rotigotine use at EOL remains commonplace and better understanding of its effect and dosing is required.
