Area of Science:

  • Clinical Microbiology
  • Laboratory Medicine
  • Quality Management in Healthcare

Context:

  • The pre-analytical phase of cytobacteriological examination of urine (CBEU) is critical for accurate diagnostic results.
  • Non-conformities in this phase can significantly affect patient diagnosis and treatment.
  • Standardized protocols are essential for ensuring the reliability of laboratory testing.

Purpose:

  • To quantitatively and qualitatively analyze pre-analytical non-conformities in CBEU.
  • To identify the most frequent types and sources of these errors.
  • To propose effective corrective measures for improving the pre-analytical process.

Summary:

  • A 76-month retrospective study analyzed 66,631 CBEU requests.
  • A significant rate of pre-analytical non-conformities (2.47%) was observed, primarily from the emergency department.

  • Deteriorated samples, delayed transport, and damaged equipment were the main issues identified.

    • Impact:

    • Frequent pre-analytical non-conformities in CBEU have direct clinical and economic consequences.
    • These errors compromise the accuracy of diagnostic information.
    • Continuous improvement initiatives are vital to enhance the pre-analytical phase and patient outcomes.
