Preconditioning with levosimendan reduces postoperative low cardiac output in moderate-severe systolic dysfunction patients who will undergo elective coronary artery bypass graft surgery: a cost-effective strategy.

BACKGROUND: Patients with moderate-severe systolic dysfunction undergoing coronary artery bypass graft have a higher incidence of postoperative low cardiac output. Preconditioning with levosimendan may be a useful strategy to prevent this complication. In this context, design cost-effective strategies like preconditioning with levosimendan may become necessary. METHODS: In a sequential assignment of patients with Left Ventricle Ejection Fraction less than 40%, two strategies were compared in terms of cost-effectiveness: standard care (n = 41) versus preconditioning with Levosimendan (n = 13). The adverse effects studied included: postoperative new-onset atrial fibrillation, low cardiac output, renal failure and prolonged mechanical ventilation. The costs were evaluated using deterministic and probabilistic sensitivity analysis, and Monte Carlo simulations were performed. RESULTS: Preconditioning with levosimendan in moderate to severe systolic dysfunction (Left Ventricle Ejection Fraction < 40%), was associated with a lower incidence of postoperative low cardiac output in elective coronary artery bypass graft surgery 2(15.4%) vs 25(61%) (P < 0.01) and lesser intensive care unit length of stay 2(1-4) vs 4(3-6) days (P = 0.03). Average cost on levosimendan group was 14,792€ while the average cost per patient without levosimendan was 17,007€. Patients with no complications represented 53.8% of the total in the levosimendan arm, as compared to 31.7% in the non-levosimendan arm. In all Montecarlo simulations for sensitivity analysis, use of levosimendan was less expensive and more effective. CONCLUSIONS: Preconditioning with levosimendan, is a cost-effective strategy preventing postoperative low cardiac output in patients with moderate-severe left ventricular systolic dysfunction undergoing elective coronary artery bypass graft surgery.

Cost-effectiveness of vaccines for the prevention of seasonal influenza in different age groups: a systematic review / Coste-efectividad de la vacunación contra la gripe estacional para diferentes grupos de edad: Una revisión sistemática

BACKGROUND: Given the economic burden of seasonal influenza for the healthcare system, we performed a systematic review aiming to update available evidence on the cost-effectiveness of vaccination of seasonal influenza in different age groups, including children. METHODS: A systematic review of the literature on economic evaluations of seasonal influenza vaccination programs in children and adults was carried out. The following databases were searched (January 2013 - April 2018): Medline and PREMEDLINE, EMBASE, EconLit and databases of the Centre for Reviews and Dissemination (DARE, HTA, NHS EED). RESULTS: A total of 11 economic evaluations were included. Methodological quality of included studies was acceptable. Scientific evidence shows that seasonal influenza vaccination programs in school-age children can be a cost-effective alternative from national health system perspective and can be cost-saving from societal perspective in European countries. However, available evidence does not allow us to conclude that influenza vaccination programs in healthy adults under 65 years of age were a cost-effective alternative in our context, due to the high uncertainty and the lack of studies carried out in Spanish context. CONCLUSIONS: Vaccination programs for the prevention of seasonal influenza in school-age children (3-16 years) can be a cost-effective strategy.

OBJETIVO: Dada la carga económica que supone para el sistema sanitario la gripe estacional, se plantea esta revisión sistemática cuyo objetivo fue actualizar la evidencia disponible sobre el coste-efectividad de vacunación contra la gripe estacional en diferentes grupos de edad, incluyendo población infantil. METODOS: Se llevó a cabo una revisión sistemática de la literatura de evaluaciones económicas de los programas de vacunación contra la gripe estacional en niños y adultos. Se realizaron búsquedas en las bases de datos (enero 2013 ­ abril 2018): Medline y PREMEDLINE, EMBASE, EconLit y en las bases de datos del Centre for Reviews and Dissemination (DARE, HTA, NHS EED). RESULTADOS: Se incluyeron 11 evaluaciones económicas. La calidad metodológica de los estudios incluidos fue buena. La evidencia científica muestra que los programas de vacunación contra la gripe estacional en niños en edad escolar pueden ser una estrategia coste-efectiva desde la perspectiva sanitaria en países europeos. La evidencia científica disponible hasta el momento no nos permite concluir que los programas de vacunación antigripal en adultos sanos de menos de 65 años de edad sean una alternativa costeefectiva en nuestro contexto, debido a la elevada incertidumbre existente y a la escasez de estudios realizados en el contexto español. CONCLUSIONES: Los programas de vacunación contra la gripe estacional en niños en edad escolar (3-16 años) pueden ser una estrategia coste-efectiva desde la perspectiva del SNS.

Cost-effectiveness of cell-free DNA in maternal blood testing for prenatal detection of trisomy 21, 18 and 13: a systematic review.

The aim of this paper was to conduct a systematic review of the cost-effectiveness of the analysis of cell-free DNA in maternal blood, often called the non-invasive prenatal test (NIPT), in the prenatal screening of trisomy in chromosomes 21, 18 and 13. MEDLINE, MEDLINE in process, EMBASE, and Cochrane Library were searched in April 2017. We selected: (1) economic evaluations that estimated the costs and detected cases of trisomy 21, 18 or 13; (2) comparisons of prenatal screening with NIPT (universal or contingent strategies) and the usual screening without NIPT, (3) in pregnant women with any risk of foetal anomalies. Studies were reviewed by two researchers. Data were extracted, the methodological quality was assessed and a narrative synthesis was prepared. In total, 12 studies were included, four of them performed in Europe. Three studies evaluated NIPT as a contingent test, three studies evaluated a universal NIPT, and six studies evaluated both. The results are heterogeneous, especially for the contingent NIPT where the results range from NIPT being dominant to a dominated strategy. Universal NIPT was found to be more effective but also costlier than the usual screening, with very high incremental cost-effectiveness ratios. One advantage of screening with NIPT is lower invasive procedure-related foetal losses than with usual screening. In conclusion, the cost-effectiveness of contingent NIPT is uncertain according to several studies, while the universal NIPT is not cost-effective currently.
