Design outcomes

Primary

MeasureTime frame
Current information as of 29/09/10: Death or maternal infectious morbidity (one or more of the following: antibiotic use for maternal febrile morbidity during postnatal hospital stay, antibiotic use for endometritis, wound infection or peritonitis) or further operative procedures; or blood transfusion of >1 unit of whole blood or packed cells. Initial information at time of registration: Death or serious maternal morbidity (one or more of the following: antibiotic use for maternal febrile morbidity during postnatal hospital stay, antibiotic use for endometritis or wound infection; further operative procedures on the wound; blood transfusion).

Blood transfusion 8. Interventions used for severe primary Post-Partum Haemorrhage (PPH) 9. Stillbirth after trial entry 10. Apgar score less than three at five minutes 11. Laceration of baby at time of caesarean section 12. Death of the baby by six weeks of age 13. Other severe maternal morbidity Health service utilisation: 1. Duration of operation (from incision to closure) 2. Duration of hospital stay post-caesarean section 3. Duration of stay in Intensive Care Unit post-caesarean section 4. Number and duration of re-admissions to hospital within six weeks of the caesarean section Added as of 13/03/2013: Follow-up Study Outcomes Women?s health and mortality 1. Following the CORONIS birth and before any subsequent pregnancy, any new onset or worsening of: 1.1. pelvic pain 1.2. dysmenorrhoea 1.3. deep dyspareunia 1.4. urinary symptoms of poor stream and/or frequency which did not respond to antibiotics 2. Diagnostic laparoscopy or diagnostic laparotomy (not related to pregnancy) 3. Hysterectomy or tubal/ovarian surgery (not related to pregnancy) 4. Bladder or bowel damage in those women who have had surgery, excluding diagnostic laparoscopy and diagnostic laparotomy (not related to pregnancy). 5. Following the CORONIS birth, any new onset of: 5.1. abdominal hernia 5.2. bowel obstruction 6. Woman?s death Reproductive status 7. Number of women with no subsequent pregnancy 7.1. Voluntary infertility 7.2. Involuntary infertility 8. Use of fertility treatments Subsequent pregnancies 9. Number of women having any subsequent pregnancy and for these women, the following outcomes will be measured: 9.1.
