Design outcomes

Primary

MeasureTime frame
Primary outcome will be a composite of stillbirth, neonatal mortality and neonatal morbidity. Stillbirth is defined as intrauterine foetal death of a foetus that was alive at randomisation. Neonatal mortality is defined as live births with death day 0-27. Neonatal morbidity is defined as at least one of the following variables: Apgar score 12 mmol/l in umbilical artery or pH <7.00 in umbilical artery, HIE I-III, intracranial haemorrhage, neonatal convulsions, meconium aspiration syndrome (MAS), mechanical ventilation, obstetric brachial plexus injury.

Secondary

MeasureTime frame
Current secondary outcome measures as of 14/04/2020: 1. Secondary neonatal outcomes 1.1. Perinatal mortality, stillbirths and neonatal mortality assessed from patient notes on live births with death at 0 to 27 days 1.2. Stillbirths assessed from patient notes at 0 days 1.3. Neonatal mortality assessed from patient notes on live births with death at 0 to 27 days 1.4. Neonatal morbidity (at least one of the following variables: Apgar score 12 mmol/l in umbilical artery or pH 12 mmol/l in umbilical artery or pH 1000 ml) 4.10. Duration of labour (minutes) 4.11. Wound infection 4.12. Urinary tract infection 4.13. Endometritis, sepsis 4.14. Breastfeeding at discharge and 4 weeks after childbirth 4.15. Women’s attitudes and experiences at randomisation (Sub study) The following data on women’s attitudes, experiences and health-related quality of life will be collected by questionnaires (web based or postal): at randomisation in subpopulations in Gothenburg, Falun and Örebro 4.15.1 Personality (Big Five) 4.15.2 Health related quality of life (Euro-Qol –VAS & Euro-Qol-5D) 4.15.3 Depression/anxiety (HADS), 4.15.4 Self-efficacy (The General Self-Efficacy Scale [GES]) 4.16. Women’s attitudes and experiences 3 months after randomisation. The following data on women’s attitudes, experiences and health-related quality of life will be collected by questionnaires (web-based or postal) 3 months after randomisation in subpopulations in Gothenburg, Falun and Örebro 4.16.1 Health-related quality of life (Euro-Qol –VAS & Euro-Qol-5D) 4.16.2 Depression/anxiety (HADS) 4.16.3 Self-efficacy (The General Self-Efficacy Scale [GES])
