Cost-effectiveness of red blood cell transfusion vs. non-intervention in women with acute anaemia after postpartum haemorrhage.

BACKGROUND: Red blood cell (RBC) transfusion is frequently used to treat women with acute anaemia after postpartum haemorrhage. We aimed to assess the economic consequences of red blood cell transfusion compared to non-intervention in these women. METHODS: A trial-based cost-effectiveness analysis was performed alongside the Well-Being of Obstetric patients on Minimal Blood transfusions (WOMB) trial. Women with acute anaemia [Hb 4·8-7·9 g/dl (3·0-4·9 mm)] after postpartum haemorrhage, without severe anaemic symptoms, were randomly allocated to RBC transfusion or non-intervention. Primary outcome of the trial was physical fatigue (Multidimensional Fatigue Inventory, scale 4-20; 20 represents maximal fatigue). Total costs per arm were calculated using a hospital perspective with a 6 weeks time horizon. RESULTS: Per woman, mean costs in the RBC transfusion arm (n = 258) were €1957 compared to €1708 in the non-intervention arm (n = 261; P = 0·024). The 13% difference in costs between study arms predominantly originated from costs of RBC units, as costs of RBC units were six times higher in the RBC transfusion arm. RBC transfusion led to a small improvement in physical fatigue of 0·58 points per day; thus, the costs to improve the physical fatigue score with one point would be €431. CONCLUSION: In women with acute anaemia after postpartum haemorrhage (PPH), RBC transfusion is on average €249 more expensive per woman than non-intervention, with only a small gain in HRQoL after RBC transfusion. Taking both clinical and economic consequences into account, implementation of a non-intervention policy seems justified.

Cost-effectiveness of induction of labour at term with a Foley catheter compared to vaginal prostaglandin E2 gel (PROBAAT trial).

OBJECTIVE: To assess the economic consequences of labour induction with Foley catheter compared to prostaglandin E2 gel. DESIGN: Economic evaluation alongside a randomised controlled trial. SETTING: Obstetric departments of one university and 11 teaching hospitals in the Netherlands. POPULATION: Women scheduled for labour induction with a singleton pregnancy in cephalic presentation at term, intact membranes and an unfavourable cervix; and without previous caesarean section. METHODS: Cost-effectiveness analysis from a hospital perspective. MAIN OUTCOME MEASURES: We estimated direct medical costs associated with healthcare utilisation from randomisation to 6 weeks postpartum. For caesarean section rate, and maternal and neonatal morbidity we calculated the incremental cost-effectiveness ratios, which represent the costs to prevent one of these adverse outcomes. RESULTS: Mean costs per woman in the Foley catheter group (n = 411) and in the prostaglandin E2 gel group (n = 408), were €3297 versus €3075, respectively, with an average difference of €222 (95% confidence interval -€157 to €633). In the Foley catheter group we observed higher costs due to longer labour ward occupation and less cost related to induction material and neonatal admissions. Foley catheter induction showed a comparable caesarean section rate compared with prostaglandin induction, therefore the incremental cost-effectiveness ratio was not informative. Foley induction resulted in fewer neonatal admissions (incremental cost-effectiveness ratio €2708) and asphyxia/postpartum haemorrhage (incremental cost-effectiveness ratios €5257) compared with prostaglandin induction. CONCLUSIONS: Foley catheter and prostaglandin E2 labour induction generate comparable costs.

Induction versus expectant monitoring for intrauterine growth restriction at term: randomised equivalence trial (DIGITAT).

OBJECTIVE: To compare the effect of induction of labour with a policy of expectant monitoring for intrauterine growth restriction near term. DESIGN: Multicentre randomised equivalence trial (the Disproportionate Intrauterine Growth Intervention Trial At Term (DIGITAT)). SETTING: Eight academic and 44 non-academic hospitals in the Netherlands between November 2004 and November 2008. PARTICIPANTS: Pregnant women who had a singleton pregnancy beyond 36+0 weeks' gestation with suspected intrauterine growth restriction. INTERVENTIONS: Induction of labour or expectant monitoring. MAIN OUTCOME MEASURES: The primary outcome was a composite measure of adverse neonatal outcome, defined as death before hospital discharge, five minute Apgar score of less than 7, umbilical artery pH of less than 7.05, or admission to the intensive care unit. Operative delivery (vaginal instrumental delivery or caesarean section) was a secondary outcome. Analysis was by intention to treat, with confidence intervals calculated for the differences in percentages or means. RESULTS: 321 pregnant women were randomly allocated to induction and 329 to expectant monitoring. Induction group infants were delivered 10 days earlier (mean difference -9.9 days, 95% CI -11.3 to -8.6) and weighed 130 g less (mean difference -130 g, 95% CI -188 g to -71 g) than babies in the expectant monitoring group. A total of 17 (5.3%) infants in the induction group experienced the composite adverse neonatal outcome, compared with 20 (6.1%) in the expectant monitoring group (difference -0.8%, 95% CI -4.3% to 3.2%). Caesarean sections were performed on 45 (14.0%) mothers in the induction group and 45 (13.7%) in the expectant monitoring group (difference 0.3%, 95% CI -5.0% to 5.6%). CONCLUSIONS: In women with suspected intrauterine growth restriction at term, we found no important differences in adverse outcomes between induction of labour and expectant monitoring. Patients who are keen on non-intervention can safely choose expectant management with intensive maternal and fetal monitoring; however, it is rational to choose induction to prevent possible neonatal morbidity and stillbirth. TRIAL REGISTRATION: International Standard Randomised Controlled Trial number ISRCTN10363217.

[Complicated but successful resuscitation after amniotic fluid embolism]. / Een gecompliceerde, doch geslaagde resuscitatie na een vruchtwaterembolie.

A 33-year-old woman, gravida IV, para III with unexplained polyhydramnios was admitted to give birth at 29 weeks of pregnancy. Directly after the spontaneous breaking of the membranes, asystolia occurred. Following emergency resuscitation the sinus rhythm returned. Upon the relaparotomy due to a large filling requirement and increasing abdomen size, 'crush' lesions to the spleen and liver were visible; following this a splenectomy was carried out and tampons applied to the liver. After seven months the patient had slight residual symptoms; three weeks after his birth her son was transferred in good condition to another hospital. Amniotic fluid embolism is a rare complication of pregnancy with often serious complications for mother and child. The diagnosis is based on the clinical symptoms of cardiac arrest or sudden profound shock, acute respiratory failure, and/or disseminated intravascular coagulation, occurring in most cases during or soon after delivery, in the absence of an alternative cause (in particular primary cardiopulmonary causes). If the clinical picture deviates from the expected post-resuscitation course alternative diagnoses or resuscitation injuries must be considered.
