Abstract
Background: This cross-sectional multicentric survey study aimed to assess the quality of the extra-analytical phase of laboratory activities in some developing European countries and Mexico. We assessed the quality of the extra-analytical practices in participating laboratories regarding the: a) sample acceptance criteria; b) phlebotomy procedures; c) test results reporting and d) recording non-conformities.Methods: A survey was performed during the April–May 2009. A total of 15 clinical laboratories from the following countries were included: Bosnia, Croatia, Czech Republic, Hungary, Mexico, Poland, Portugal, Romania, Serbia and Ukraine. Questions were scored (scores from 1–4) and average scores was calculated for each category.Results: The overall score for all respondents (n=443) was 3.10±0.33. The average score was 3.11±0.56 for sample acceptance criteria, 2.76±0.58 for phlebotomy and 3.34± 0.53, for test results reporting (F=116.49; pConclusions: The overall quality of the extra-analytical practices in countries in this survey is not satisfactory. Phlebotomy practices are the most critical extra-analytical activity. Since laboratory accreditation was associated with better practices and higher overall quality of the extra-analytical procedures, we believe that the most significant improvement could be made by implementing the total quality management system and standardizing laboratory procedures.
