Recommendations of activity restriction in high-risk pregnancy scenarios: a Danish national survey

To describe specific recommendations of activity restriction, place of care, expected beneficial and adverse effects, and recommended antithrombotic prophylaxis in nine clinical scenarios.

A national survey. All members of the Danish Society of Obstetrics and Gynaecology and the Danish Association of Midwives were asked to complete a tested, structured questionnaire.

We sent 1815 invitations; the overall response rate was 54%. A majority of clinicians recommended some form of activity restriction in the nine scenarios. The midwives recommended strict or moderate activity restriction more often than obstetricians in five of the nine scenarios, in women with preterm premature rupture of membranes, preterm labour, cervical ripening, total placenta praevia, and intrauterine growth restriction, whereas no differences were found in the remaining scenarios. Compared to the obstetricians, the midwives also reported that they expected the recommendation to be more effective. Most midwives and obstetricians reported that they thought strict activity restriction was associated with severe or moderate adverse effect, and recommended antithrombotic prophylaxis.

Danish obstetricians and midwives prescribe activity restriction in most high-risk pregnancies. The degree of activity restriction and the presumed effect vary between clinicians. This may reflect different attitudes and lack of guidelines based on clinical studies of a possible benefit of activity restriction.
