Purpose

Postpartum haemorrhage (PPH) is one of the top five causes of maternal mortality in developed and developing countries. The most important treatment of PPH is red blood cell (RBC) transfusion. The decision whether to prescribe RBC transfusion is mostly based on postpartum haemoglobin (Hb) values. RBC transfusion should be aimed to reduce morbidity and especially to improve Health Related Quality of Life (HRQoL). The goal of the WOMB study is to assess the effect of RBC transfusion on HRQoL and to confirm the role of HRQoL in deciding whether RBC transfusion is necessary.

Primary Outcome Measures:

Physical Fatigue [ Time Frame: on day 3 postpartum ] [ Designated as safety issue: No ]
measured with the MFI questionnaire

Secondary Outcome Measures:

Health related quality of life [ Time Frame: delivery - six weeks postpartum ] [ Designated as safety issue: No ]
Health related quality of life measured with the following questionnaires: Euro-Qol, SF-36 and the MFI
Blood usage and the costs [ Time Frame: delivery - six weeks postpartum ] [ Designated as safety issue: No ]
Hemoglobin increase after transfusion [ Time Frame: before- after transfusion ] [ Designated as safety issue: No ]
Hb value and platelet count will be measured before and after red blood cell transfusion
Heart beat, blood pressure, temperature [ Time Frame: before- after transfusion ] [ Designated as safety issue: No ]
heart beat per minute, blood pressure, temperature will be measured before and after red blood cell transfusion
Hospital stay [ Time Frame: delivery - six weeks postpartum ] [ Designated as safety issue: Yes ]
the hospital stay after delivery will be compared between both arms. All admissions in the first 6 weeks postpartum will be registered
Physical complications (infections, thromboembolic events, hemodynamic events, cardiac events, neurologic events, secondary HPP, obstetric interventions, 'rescue' RBC transfusion) with WHO CTC grade 2 or more. [ Time Frame: delivery - six weeks postpartum ] [ Designated as safety issue: Yes ]
all complications and admissions in the first 6 weeks postpartum will be registered

Enrollment:	500
Study Start Date:	May 2004
Primary Completion Date:	March 2011 (Final data collection date for primary outcome measure)

Arms	Assigned Interventions
Active Comparator: Red blood cell transfusion At least one unit of red blood cells will be administered.	Other: Red blood cell transfusion At least one unit of red blood cells will be administered. The target Hb value after transfusion is at least 8.7 g/dL.
No Intervention: Control No red blood cell transfusion. Iron suppletion is allowed and can be administered according to local protocol. If suppletion is prescribed, the type and duration will be registered

Detailed Description:

The WOMB study is a multicenter trial in patients with PPH, where a restrictive RBC transfusion policy will be compared with a more liberal RBC transfusion policy. Primary outcome in this study is fatigue measured with the MFI questionnaire. Inclusion criteria are: 1) 12-24 h after VD or CS; 2) 4.8 ≤Hb≤ 7.9 g/dL; 3) blood loss ≥ 1000mL or Hb decrease ≥ 1,9 g/dL; 4) age≥ 18 years; 5) no anaemic symptoms. Patients will be randomised for a RBC transfusion or not. The total follow-up period is 6 weeks. HRQoL will be measured at T=0 (12-24 hours postpartum) 3 days, 1, 3 and 6 weeks postpartum. At T=0 and 6 weeks postpartum Hb value will be measured. For the patients who receive a RBC transfusion, the effect of the RBC transfusion will be measured with the Hb value, Hct, platelet and leukocyte count, and the temperature of the patient before and after the RBC transfusion. The sample size is 500 patients: 250 allocated to a RBC transfusion and 250 patients allocated to a restrictive policy.
