| Abstrakt: | Objective: This study aimed at identifying associations between the participation of transfusion services in immunohematology external quality control programs and their accuracy in immunohematology testing and adaptation to technical and legal operational procedures. Methods: From 2007 to 2009, a cross-sectional study was conducted in 219 transfusion services of the State of Minas Gerais who participated in this investigation by responding to a questionnaire and conducting a proficiency test comprising: ABO and RhD phenotyping, irregular RBC antibody screening and cross-matching. Frequencies and bivariate analysis followed by binary logistic regression were used for statistical analysis. Results: Transfusion services who participated in external quality control programs (32.4%) and those that did not (67.6%) obtained worrying error percentages in proficiency tests which may significantly increase blood transfusion risks. Shortfalls related to the establishment of protocols, standards and internal quality control were also significant. On comparing the two groups, transfusion services that participated in these programs had a 2.35 times higher chance of correct results in the proficiency panel testing, a 3.16 higher chance of having transfusional records and a 2.81 higher chance of performing preventive maintenance of equipment. Conclusion: The study showed that independent factors associated to participation in external quality control programs suggest that more investment in internal quality control procedures is necessary and that more attention should be paid to current legislation. |
