Amyotrophie spinale type 1 : enquête multicentrique des pratiques de soins et d’accompagnement palliatif sur deux périodes successives de 10 ans

Abstract

Questions about care practices and the role of palliative care in pediatric neurodegenerative diseases have led the Neuromuscular Committee of the French Society of Neurology to conduct a retrospective study in spinal muscular atrophy type 1, a genetic disease most often leading to death before the age of 1 year. A retrospective multicenter study from pediatricians included in the reference centers of pediatric neuromuscular diseases was carried out on two 10-year periods (1989-1998 and 1999-2009). The 1989-1998 period included 12 centers with 106 patients, the 1999-2009 period 13 centers with 116 children. The mean age of onset of clinical signs was 2.1 months (range, 0-5.5 months), the median age at diagnosis was 4 months (range, 0-9 months) vs 3 months. The median age of death was 7.5 months (range, 0-24 months) vs 6 months. The care modalities included physiotherapy (90 %), motor support (61 % vs 26 % for the previous period), enteral nutrition by nasogastric tube (52 % vs 24 %), and 3.4 % of children had a gastrostomy (vs 1.8 %). At home, pharyngeal aspiration was used in 64 % (vs 41 %), oxygen therapy in 8 %, noninvasive ventilatory support in 7 %. The mean age at death was 8.1 months (range, 0-24 months) vs 7 months, the time from diagnosis to death was 4 months vs 3 months. Death occurred at home in 23 % vs 17 %, in a pediatric unit in 62 % vs 41 %. The use of analgesics and sedative drugs was reported in 60 % of cases: 40 % morphine (vs 18 %) and benzodiazepines in 48 % (vs 29 %). Respiratory support was limited mostly to oxygen by nasal tube (55 % vs 54 %), noninvasive ventilation in 9 % of the cases, and intubation and assisted mechanical ventilation (2 %). These results confirm a change in practices and the development of palliative care in children with a French consensus of practices quite different from the standard care in North-America and closer to the thinking of English medical teams. A prospective study within the 2011 national hospital clinical research program (PHRC 2011) is beginning in order to evaluate practices and the role of families and caregivers.
