- Methodological guidelines for reducing the complexity of data warehouse development for transactional blood bank systems(2013) TAKECIAN, Pedro L.; OIKAWA, Marcio K.; BRAGHETTO, Kelly R.; ROCHA, Paulo; LUCENA, Fred; KAVOUNIS, Katherine; SCHLUMPF, Karen S.; ACKER, Susan; CARNEIRO-PROIETTI, Anna B. F.; SABINO, Ester C.; CUSTER, Brian; BUSCH, Michael P.; FERREIRA, Joao E.Over time, data warehouse (DW) systems have become more difficult to develop because of the growing heterogeneity of data sources. Despite advances in research and technology, DW projects are still too slow for pragmatic results to be generated. Here, we address the following question: how can the complexity of DW development for integration of heterogeneous transactional information systems be reduced? To answer this, we proposed methodological guidelines based on cycles of conceptual modeling and data analysis, to drive construction of a modular DW system. These guidelines were applied to the blood donation domain, successfully reducing the complexity of DW development.

- Analysis of donor deferral at three blood centers in Brazil(2013) GONCALEZ, Thelma T.; SABINO, Ester C.; SCHLUMPF, Karen S.; WRIGHT, David J.; MENDRONE, Alfredo; LOPES, Maria I.; LEAO, Silvana; MIRANDA, Carolina; CAPUANI, Ligia; CARNEIRO-PROIETTI, Anna Barbara F.; BASQUES, Fernando; FERREIRA, Joao E.; BUSCH, Michael; CUSTER, BrianBACKGROUND: The safety of the blood supply is ensured through several procedures from donor selection to testing of donated units. Examination of the donor deferrals at different centers provides insights into the role that deferrals play in transfusion safety. STUDY DESIGN AND METHODS: A cross-sectional descriptive study of prospective allogeneic blood donors at three large blood centers located in SAo Paulo, Belo Horizonte, and Recife, Brazil, from August 2007 to December 2009 was conducted. Deferrals were grouped into similar categories across the centers, and within each center frequencies out of all presentations were determined. RESULTS: Of 963,519 prospective blood donors at the three centers, 746,653 (77.5%) were accepted and 216,866 (22.5%) were deferred. Belo Horizonte had the highest overall deferral proportion of 27%, followed by Recife (23%) and SAo Paulo (19%). Females were more likely to be deferred than males (30% vs. 18%, respectively). The three most common deferral reasons were low hematocrit or hemoglobin, medical diagnoses, and higher-risk behavior. CONCLUSION: The types and frequencies of deferral vary substantially among the three blood centers. Factors that may explain the differences include demographic characteristics, the order in which health history and vital signs are taken, the staff training, and the way deferrals are coded by the centers among other policies. The results indicate that blood donor deferral in Brazil has regional aspects that should be considered when national policies are developed.
