Summary of “Modulo 6.1 (Parte 2) - Calidad en Anatomía Laboratorio”

This video focuses on quality management in the laboratory setting, specifically in anatomical pathology. It covers the analytical, post-analytical, and general laboratory phases, emphasizing the importance of quality assurance measures, risk management, continuous improvement, and staff competence to ensure accurate, reliable, and safe laboratory testing.

Main Ideas and Concepts

1. Analytical Stage: Incorporating a New Test

Automation improves quality by standardizing tests, but validation is crucial to avoid inaccurate results.
Key quality and safety risks when introducing new tests must be managed through a comprehensive checklist including:
- Validation of analytical accuracy and precision (results must be both truthful and consistent).
- Definition of reportable and analytical ranges.
- Establishment or adjustment of reference ranges, especially if methodology changes.
- Assessment of analytical sensitivity and specificity.
- Definition of any necessary calculations or interpretations.
- Verification of data transfer interfaces (e.g., between instruments and laboratory information systems).
- External quality control registration and alternative validation if commercial controls are unavailable.
- Sample workflow design to minimize errors (sample collection, storage, transport).
- Authentication rules and system harmonization to ensure consistent results across platforms.
- Training and education on test specifics, including interfering substances and cross-reactions.
- Backup plans for failures and reagent/batch checks.

2. Continuous Quality Management

Ongoing risk assessment and control measures are necessary to maintain test system performance.
Key components include:
- Calibration and calibration verification according to manufacturer recommendations.
- Quality control (QC) using samples with known analyte concentrations.
- Defining QC protocols including type, frequency, control limits, and corrective actions when systems are out of control.
- Preventive maintenance and operational checks of instruments as per manufacturer or laboratory-established protocols.
- Validation of new reagent batches and shipments.
- Participation in external proficiency testing programs to assess laboratory competence.
- Root cause analysis and corrective actions following deficiencies or errors.

3. Post-Analytical Operations

Focus on reporting, interpreting, and correcting laboratory results:
- Reports must include essential patient and test information, be clearly formatted, and communicate critical values or corrections effectively.
- Interpretation guidance in reports is important as healthcare professionals may lack training in lab result usage.
- Errors in reports must be corrected promptly, with both original and corrected versions documented.
- All errors should be treated as incidents requiring investigation to prevent recurrence.

4. General Laboratory Quality Management

Personnel management:
- New staff introduction is a vulnerable period; requires thorough training, background checks, competency assessments, and integration into quality systems.
- Competency must be evaluated at least semi-annually during the first year and annually thereafter.
Information management:
- Includes handling patient data, policies, quality records, and administrative info.
- Must ensure retention, security, privacy, and regulatory compliance.
Turnaround time (TAT):
- Defined and monitored for each test, with monthly compliance checks.
Laboratory organization:
- Clear assignment of responsibilities, delegation, and fostering a culture of quality and patient safety.
- Culture must be embraced at all organizational levels to be effective.
Continuous Quality Improvement (CQI):
- Goes beyond risk mitigation by learning from patient/client feedback and incident analyses.
- Clients include patients, doctors, nurses, administrators, insurers.
- Feedback mechanisms include satisfaction surveys (internal and external), focus groups, and data-driven actions.
- Incident management system for identifying, investigating, and preventing recurrence of errors or deviations.
- A culture of safety and accessible reporting systems are essential.

5. Quality Management Plan (QMP)

A formal document describing how the laboratory ensures quality and patient safety.
Includes:
- Indicators and monitoring activities (e.g., patient/sample ID errors, TAT compliance, critical value reporting, result modifications, contamination rates).
- Safety and biosecurity protocols.
- Equipment maintenance and standard operating procedures (SOPs).
- Internal and external audits (e.g., by College of American Pathologists).
- Documentation control.
Each laboratory sector may have its own specific quality plan tailored to its methods and automation level.
Examples of monitored indicators and their use in quality improvement were presented.
