Women's decisional conflict in the pathway of prenatal screening and testing: an explorative study within Finnish public maternity care

Patient reported pregnancy and birth outcomes in genetic neuromuscular diseases

Pregnancy and birth in women with neuromuscular conditions has been associated with more rapid disease progression and obstetric complications. This study assessed the impact of functional status and specific diagnosis on patient reported pregnancy and birth outcomes in 26 genetic neuromuscular diseases. Pregnancy and birth outcomes were collected through electronic patient questionnaires and analysed by mobility group and diagnosis. Free text responses were grouped into themes. 721 pregnancies were reported by 305 women. Miscarriage (21% of pregnancies), caesarean delivery (38% of births) and instrumental vaginal delivery (19% of births) were all more frequent in respondents than in the general population (p<0.05), and were more common in those who were non-ambulant at conception than other mobility levels (p <0.05). Falls occurred during 42% of pregnancies and a deterioration in muscle strength during 43%. There was not an increased incidence of maternal complications, apart from maternal hypertension which was more common in limb girdle muscular dystrophy 2A/R1 (35%) and myotonic dystrophy (24%). Patients offered specific practical advice to prospective mothers. Women with neuromuscular conditions have a more complex antenatal and perinatal course than unaffected women. Prenatal counselling, specialist obstetric review and additional occupational therapy support should be considered.
