    Abstract:

    Introduction: Transfusion is a mechanism of transmission of Chagas’ disease. There are no studies on the costs of the screening test in Colombian Blood banks.Objective: To estimate the costs of the screening test for Chagas’ disease among Blood donors in two Colombian Blood banks, 2015.Materials and methods: We conducted a micro-costing study from the perspective of the health care provider to estimate the cost of Chagas’ disease testing in two Blood banks, Banco de Sangre de la Cruz Roja, Seccional Bolívar, and Banco de Sangre del Hospital de Yopal, Casanare, taking into account four cost categories: 1) Administrative costs: public services and insurance costs were calculated based on the Blood bank area in square meters; 2) capital costs: building and equipment costs that were annualized using a 3% discount rate and a lifespan of 20 years for building and five for equipment; 3) costs of Chagas’ disease test materials and reagents adjusted by Blood bank production level, and 4) costs of staff in charge of Chagas’ disease test processing. The costs of transfusion Bagsand immunohematology tests are also reported.Results: The cost of Chagas’ disease test in the Blood bank of Seccional Bolívar was COP$ 37,804 (USD$ 12), and the Blood Bag and immunohematology test costs were COP$ 25,941 (USD$ 8.2) and COP$ 6,800 (USD$ 2.2), respectively. In the Blood bank of Yopal, Casanare, the costs were COP$ 77,384 (USD$ 24.6), COP$ 30,141 (USD$ 9.6) and COP$ 12,627 (USD$ 4), respectively. Personnel cost accounted for the highest percentage of the total cost for both Blood banks (47.5% in Seccional Bolívar, and 55.7% in Yopal, Casanare).Conclusion: Our results are an important input for the planning of services and cost-effectiveness studies for screening tests for Chagas’ disease in Colombian Blood banks.Introducción. La transfusión es un mecanismo de transmisión de la enfermedad de Chagas. No se han hecho estudios de costos de la prueba de tamización en bancos de sangre de Colombia.Objetivo. Estimar los costos de la prueba de tamización para la enfermedad de Chagas en donantes de bancos de sangre de Colombia, 2015.Materiales y métodos. Se hizo un estudio de costos desde la perspectiva del prestador de servicios en los bancos de sangre de la Cruz Roja, seccional Bolívar, y del Hospital de Yopal, Casanare, que incluyó: 1) gastos administrativos, es decir, costos de servicios públicos y seguros asignados según los metros cuadrados de las instalaciones del banco de sangre; 2) costos de capital, es decir, edificación y equipos, anualizados con una tasa de descuento de 3 % y considerando una vida útil de 20 y cinco años, respectivamente; 3) costos de insumos y materiales ajustados al nivel de producción, y 4) costos del recurso humano encargado del procesamiento de las pruebas. Se reportó, asimismo, el costo de las bolsas y de las pruebas de inmunohematología.Resultados. En el banco de sangre de la Cruz Roja, seccional Bolívar, el costo de la prueba fue de COP$ 37.804 (USD$ 12), mientras que la bolsa y la prueba de inmunohematología costaron COP$25.942 (USD$ 8,2) y COP$ 6.800 (USD$ 2,2), respectivamente. En el banco de sangre del Hospital de Yopal, los costos ascendieron a COP$ 77.384 (USD$ 24,6), COP$ 30.141 (USD$ 9,6) y COP$ 12.627 (USD$ 4), respectivamente. La mayor participación en el costo de la prueba correspondió al recurso humano (47,5 % en Cartagena y 55,7 % en Yopal).Conclusiones. Estos resultados son importantes para la planificación de los servicios y los análisis de costo-efectividad de la prueba de tamización para la enfermedad de Chagas en los bancos de sangre

  • a smart Blood Bag management system using a load integrated u shaped near field rfid antenna array
    IEEE Transactions on Antennas and Propagation, 2019
    Co-Authors: Mingyo Jeong

    Abstract:

    For improving transfusion safety, a smart Blood Bag management system using a load-integrated U-shaped near-field antenna (LUNA) array is proposed in this paper. The proposed system consists of four LUNAs for ID sensing with Blood information and a switching circuit for the sensing of Blood Bag localization. The LUNA, which is well impedance-matched within the universal ultrahigh-frequency radio frequency identification band, operates in the near-field region for precise localization, and includes a lumped Lattice-type $LC$ -balun which is exploited to cancel out currents through the ground plane of the LUNA and to obtain opposite directional currents in order to reinforce the magnetic field between two microstrip lines in the LUNA. Using a single-pole four-throw switching circuit, a centimeter-level precise localization of Blood Bags can be achieved. The proposed system can be used to prevent the mishandling of Blood transfusions and to manage Blood Bags remotely and effectively.

  • smart Blood Bag management system in a hospital environment
    Lecture Notes in Computer Science, 2006
    Co-Authors: Soojung Kim, Sun K. Yoo, H. O. Kim, Jungji Park, Kukji Seo, Yungchul Chang

    Abstract:

    In order to provide suitable Blood transfusion samples to patients, the Blood Bag should be kept at a uniformly maintained temperature to prevent deterioration during transportation. Therefore, this paper presents a Blood monitoring and management system for use in hospitals. This system may continuously report the temperature of the Blood bank refrigerator, track the location of a Blood Bag to increase staff operation efficiency, and can confirm that the assigned Blood Bag was transported to the intended patient in need of transfusion. We developed and demonstrated the clinical usability of the combined Blood temperature management and tracking system using a ubiquitous sensor network and RFID (Radio Frequency Identification) technology.
