Abstract
Aims: (a) To evaluate the types and frequencies of preanalytical errors occurring in a tertiary care hematology diagnostic center and (b) To evaluate differences if any, across groups [outpatient data (OPD) vs inpatient data (IPD), type of test requested [complete blood count (CBC) vs coagulation] and laboratory (routine vs emergency).
Settings and Design: A prospective study was conducted over a period of nine months (August 2017-April 2018) to address the above objectives. All samples received in the clinical hematology division of our institute were included in the analysis.
Materials and Methods: Categories of preanalytical errors were defined. This included insufficient, clotted, diluted, and lipemic samples. Clerical errors such as wrong/absent sample labeling, requisition form-sample mismatch, and wrong vacutainer selection were also documented. IPD and OPD data, as well as data pertaining to samples sent for different tests [complete blood count (CBC)/coagulation] and in the routine and emergency laboratories, were segregated.
Statistical Analysis Used: All errors in each category were recorded as numbers and corresponding percentages (proportions). The two-tailed z-test was a...
