The Effectiveness of Cell Salvage in Extracorporeal Circulation Surgeries in Relation to Use of Health Resources After Use: A Systematic Review and Meta-analysis.

Background Alternatives to allogeneic blood transfusions are sought for resource management reasons and it is necessary to investigate the efficiency and efficacy on Cell Salvage use. The objective of this study is to analyze the effectiveness of the Cell Salvage system in addressing factors related to healthcare service utilization that may lead to increased healthcare expenditure. Methods A systematic review with meta-analysis was conducted through literature search in Medline, CINAHL, Scopus, Web of Science, and Cochrane Library. Inclusion criteria were studies in English/Spanish, without year restriction and Randomized Controlled Trials design, conducted in adults. Results Twenty-six studies were included in the systematic review, involving a total of 4,781 patients (nexperimental group=2,365; ncontrol group=2,416). Significant differences favored the Cell Salvage system in units of transfused Red Blood Cells, in terms of units (p=0.04; SMD=-0.42 95% CI=-0.83 to –0.02) and individuals (p=0.001; RR=0.71, 95% CI=0.60 to 0.84) transfused. No significant differences were found in ICU (p=0.93) and hospital stay duration (p=0.21), number of reoperations (p=0.68), and number of units and individuals transfused in terms of platelets (p>0.05). Conclusions Cell Salvage use holds high potential for reducing healthcare costs and indirectly contributing to improving blood and blood product reserves within blood banks. Results obtained thus far do not provide definitive evidence regarding the duration of hospital stay, ICU stay, need for reoperation, or the quantity of transfused platelets. Therefore, it is recommended to increase the number of studies to assess the impact on the economic models of the Cell Salvage system.
