Background:
Reducing errors in the preanalytical phase is difficult, which suggests the issue may be multidimensional. As such, qualitative research may be truly innovative in this context.
Method:
We carried out a descriptive study using a qualitative method incorporating 4 focus groups. Data analysis followed the principles of Grounded Theory.
Results:
We queried in each of the 4 focus groups collectively to identify weaknesses in the system. Those weaknesses that were most cited were logistics, coupled with uneven compliance with regulations.
Conclusion:
All 4 focus groups mapped out directives for future work, so that regulatory aspects, process management, communication and resources could be identified as key areas where error reduction is critical.

Quality Control
Quality control helps track data, visualize trends, and identify variations, making it easier to detect deviations that may affect the accuracy of an analysis. One way to do this is by generating a quality control chart, which...
