Abstract
AIM: To estimate the cost effectiveness and cost utility ratios of a restrictive vs liberal transfusion strategy in acute myocardial infarction (AMI) patients with anemia. METHODS AND RESULTS Patients (n = 666) with AMI and hemoglobin between 7-8 and 10 g/dL recruited in 35 hospitals in France and Spain were randomly assigned to a restrictive (n = 342) or a liberal (n = 324) transfusion strategy with 1-year prospective collection of resource utilization and quality of life using the EQ5D3L questionnaire. The economic evaluation was based upon 648 patients from the per-protocol population. The outcomes were 30-day and 1-year cost-effectiveness, with major adverse cardiovascular event averted (MACE) as the effectiveness outcome; and 1-year cost utility ratio.The 30-day incremental cost-effectiveness ratio was €33,065€ saved per additional MACE averted with the restrictive versus the liberal strategy, with an 84% probability for the restrictive strategy to be cost-saving and MACE reducing (i.e.dominant). At 1-year, the point estimate of the cost-utility ratio was 191,500 € saved per QALY gained; however cumulated MACE were outside the pre-specified non-inferiority margin, resulting in a decremental cost effectiveness ratio with a point estimate of €72,000 saved per additional MACE with the restrictive strategy. CONCLUSION In patients with acute myocardial infarction and anemia, the restrictive transfusion strategy was dominant (cost-saving and outcome-improving) at 30 days. At 1 year, the restrictive strategy remained cost-saving but clinical noninferiority on MACE was no longer maintained. TRIAL REGISTRATION ClinicalTrials.gov Identifier: NCT02648113.

Abstract
IMPORTANCE The optimal transfusion strategy in patients with acute myocardial infarction and anemia is unclear. OBJECTIVE To determine whether a restrictive transfusion strategy would be clinically noninferior to a liberal strategy. DESIGN, SETTING, AND PARTICIPANTS Open-label, noninferiority, randomized trial conducted in 35 hospitals in France and Spain including 668 patients with myocardial infarction and hemoglobin level between 7 and 10 g/dL. Enrollment could be considered at any time during the index admission for myocardial infarction. The first participant was enrolled in March 2016 and the last was enrolled in September 2019. The final 30-day follow-up was accrued in November 2019. INTERVENTIONS Patients were randomly assigned to undergo a restrictive (transfusion triggered by hemoglobin ≤8; n = 342) or a liberal (transfusion triggered by hemoglobin ≤10 g/dL; n = 324) transfusion strategy. MAIN OUTCOMES AND MEASURES The primary clinical outcome was major adverse cardiovascular events (MACE; composite of all-cause death, stroke, recurrent myocardial infarction, or emergency revascularization prompted by ischemia) at 30 days. Noninferiority required that the upper bound of the 1-sided 97.5% CI for the relative risk of the primary outcome be less than 1.25. The secondary outcomes included the individual components of the primary outcome. RESULTS Among 668 patients who were randomized, 666 patients (median [interquartile range] age, 77 [69-84] years; 281 [42.2%] women) completed the 30-day follow-up, including 342 in the restrictive transfusion group (122 [35.7%] received transfusion; 342 total units of packed red blood cells transfused) and 324 in the liberal transfusion group (323 [99.7%] received transfusion; 758 total units transfused). At 30 days, MACE occurred in 36 patients (11.0% [95% CI, 7.5%-14.6%]) in the restrictive group and in 45 patients (14.0% [95% CI, 10.0%-17.9%]) in the liberal group (difference, -3.0% [95% CI, -8.4% to 2.4%]). The relative risk of the primary outcome was 0.79 (1-sided 97.5% CI, 0.00-1.19), meeting the prespecified noninferiority criterion. In the restrictive vs liberal group, all-cause death occurred in 5.6% vs 7.7% of patients, recurrent myocardial infarction occurred in 2.1% vs 3.1%, emergency revascularization prompted by ischemia occurred in 1.5% vs 1.9%, and nonfatal ischemic stroke occurred in 0.6% of patients in both groups. CONCLUSIONS AND RELEVANCE Among patients with acute myocardial infarction and anemia, a restrictive compared with a liberal transfusion strategy resulted in a noninferior rate of MACE after 30 days. However, the CI included what may be a clinically important harm. TRIAL REGISTRATION ClinicalTrials.gov Identifier: NCT02648113.

Abstract
OBJECTIVE To estimate the cost effectiveness of tranexamic acid (TXA) use to prevent postpartum hemorrhage. DESIGN A trial-based economic evaluation. SETTING 15 French university maternity hospitals. POPULATION women enrolled in the TRAAP randomized controlled trial comparing TXA versus placebo in women with vaginal delivery. TRAAP failed to show a reduction in postpartum hemorrhage of at least 500 ml in the intervention arm but evidenced significant lower rates of secondary outcomes related to blood loss METHODS & MAIN OUTCOME MEASURES We estimated direct medical costs from within-trial hospital resources collected prospectively from the study report form. All resources were costed at their value to the hospital. We estimated incremental cost per incremental hemorrhage averted. RESULTS Among the 4,079 women in the TRAAP trial, data necessary to calculate costs were available for 3,836 (94.0%). The average total costs in the TXA and control groups were €2,278 ±388 and €2,288 ±409 per woman respectively (p= 0.79). In women with postpartum hemorrhage of at least 500 ml (trial primary endpoint), costs were €2,359±354 and €2,409±525 (p=0.14); for provider-assessed clinically significant postpartum hemorrhage and postpartum hemorrhage of at least 1000 ml, costs were respectively €2,316±347 versus €2,381±521 (p=0.22) and €2,321±318versus €2,411±590 (p=0.35) in the tranexamic and placebo groups, respectively. The probabilistic sensitivity analysis showed that the use of TXA had a 65-73% % probability of being cost saving and outcome improving. CONCLUSIONS Our findings support the use of TXA as both bleeding events and cost may be reduced 3 out of 4 times.

Abstract
Background: The benefits of single-use ultrasonic scissors in thyroid surgery are still debated. Although this device has been shown to reduce operating time compared with conventional haemostasis, its cost-effectiveness has never been demonstrated. The aim of this study was to evaluate the efficacy, cost-effectiveness and safety of ultrasonic scissors for total thyroidectomy. Methods: This was a prospective, randomized, multicentre trial conducted at 13 hospital sites. The primary endpoint was the percentage of patients with hypocalcaemia (serum calcium level below 2 mmol/l) on day 2. Secondary endpoints included postoperative complications and costs, with calculation of incremental cost differences and cost-effectiveness ratios. Results: In total, 1329 patients who underwent total thyroidectomy were included in the analysis: 670 were randomized to treatment with ultrasonic scissors and 659 to conventional haemostasis. There was no difference between groups in the rate of complications, including hypocalcaemia on day 2 (19(.)7 per cent in ultrasonic scissors group versus 20(.)3 per cent in conventional haemostasis group; P = 0.743). Median operating times were significantly shorter with ultrasonic scissors (90 versus 100 min with conventional haemostasis; P < 0.001). Total mean(s.d.) direct costs at 6 months were euro4311(1547) and euro4011(1596) respectively (P < 0.001). Conclusion: Ultrasonic scissors were no more clinically effective than conventional haemostasis, but use of these devices was more costly.

Abstract
OBJECTIVES To compare the hospital costs associated with two fluid resuscitation strategies for cirrhotic ascites: one with human albumin 20% (Vialebex 20%) and one with polygeline. METHODS Multicenter prospective randomized double-blinded comparative trial (that also compared efficacy and tolerance). The economic evaluation was based on direct medical costs throughout the follow-up period: days of hospitalization, hospital consultations, medical procedures, and fluid resuscitation products. This cost-minimization study had a 6-month follow-up period. Daily costs in euros were adjusted over a 30-day period. The study was interrupted prematurely because of an alert due to the bovine origin of the polygeline, and the inclusion objectives could therefore not be met. RESULTS The economic analysis included all patients in the efficacy population (group receiving human albumin 20%: n=30, polygeline group: n=38). It found a standardized cost per patient for 30 days of treatment that was significantly lower (p=0. 004) for human albumin 20% (median: 1915 euro; range: 1330-4105) than for polygeline (median: 4612 euro; range: 2138-12234). This difference is related mainly to a reduction in the frequency and duration of hospitalization in specialized units, but also to other aspects of management: hospitalization in other departments, specific solutions for the study products, and hospital procedures. CONCLUSION The economic results of this trial favor a fluid resuscitation strategy that uses human albumin 20% for cirrhotic patients. They are consistent with the clinical results and help assess the cost-benefit ratio of human albumin 20% for this indication.

Abstract
BACKGROUND The question of which colloid (albumin or synthetic colloids) used for plasma expansion following paracentesis or other complications requiring fluid loading in patients with cirrhosis remains controversial. AIMS To compare outcome and hospital-related cost in patients with cirrhosis treated with 20% human albumin with those treated with a synthetic colloid (3. 5% polygeline). METHODS The primary end point was occurrence of a first liver-related complication. RESULTS When the trial was prematurely discontinued because of safety concerns about bovine-derived products, 30 patients were assigned to receive albumin and 38 were assigned to receive a synthetic colloid. Sixty-three patients were included for ascites removal by paracentesis and five patients for ascites removal by paracentesis and renal impairment. The median time to first liver-related complication was not significantly longer in the albumin group (20 vs. 7 days). However, the total number of liver-related complications adjusted to a 100-day period was significantly lower in the albumin group. The median hospital cost for a 30-day period was significantly lower in the albumin group (1915 euros vs. 4612 euros). CONCLUSIONS In patients with cirrhosis and ascites, human albumin appears to be more effective in preventing liver-related complications than synthetic colloid. This may be associated with decreased hospital costs.

Abstract
OBJECTIVE To undertake a cost analysis of therapeutic strategies with plasma exchange (PE) for the treatment of patients with Guillain-Barre syndrome. DESIGN A randomized clinical trial including 556 patients with Guillain-Barre syndrome. We demonstrated that in the group with mild disease (walking possible) two PEs were more effective than none in shortening the time to beginning motor recovery. In the groups with moderate disease (walking impossible) and or severe disease (mechanically ventilated patients) four sessions were more effective than two and no more effective than six in shortening the time to recovery of walking with assistance and for the recovery rate of full muscle strength within 1 year. Data on outcomes and costs was collected. Complete cost data were available on 546 from the 556 patients of the trial. Costs were estimated from the viewpoint of the healthcare system and computed over a 1-year period. Because the analysis of medical outcomes did not show any difference regarding mortality but only on intermediate short-term and long-term outcomes, we carried out a cost minimization analysis. RESULTS In two groups a dominant strategy appeared, with greater efficacy and lower costs in the two-PE arm for the mild group: 21,353 euros vs. 38,753 euros and in the four-PE arm in the moderate group: 59,480 euros vs. 80,737 euros. In the severe group four PEs were as efficient and somewhat less expensive than six: 57,621 vs. 61,056 euros. CONCLUSION The treatment of Guillain-Barre syndrome by PE at the onset of disease appears to have medical justification. The least expensive strategies are either more or equally efficient as more expensive strategies.
