Summary of “Modulo 6.1 (Parte 1) - Calidad en Anatomía Laboratorio”
This video, presented by Susana Legal, provides an in-depth overview of quality management and patient safety in clinical laboratories. It is structured around four main content areas.
Main Ideas and Concepts
1. Approaches to Quality Management and Patient Safety
Various philosophies exist for promoting quality and safety in laboratories, ranging from well-established to more theoretical or transient approaches. Five key approaches are summarized below:
-
Statistical Process Control (SPC)
- Also called statistical laboratory quality control.
- Uses statistical methods to monitor and control quality with relatively few measurements.
- Helps detect when processes deviate from expected performance.
- Steps in SPC:
- Define the process to control.
- Specify operational definitions of satisfactory performance.
- Take preliminary measurements focusing on problematic steps.
- Systematically measure key production steps and graph data (trend diagrams).
- Identify causes of variation and eliminate them.
- Graph performance on control charts once special cause variation is removed.
- When control limits are exceeded, identify causes of variation.
- Applied daily in internal quality control across automated and manual processes.
-
Total Quality Management (TQM)
- Developed post-WWII in Japan, influenced by Deming, Juran, and Ishikawa.
- Focuses on organizing the lab to implement SPC effectively.
- Emphasizes employee empowerment, leadership, training, trust-building, and involvement of all organizational levels.
- Key elements:
- Continuous improvement of production and services.
- Training in daily processes.
- Leadership commitment and quality planning.
- Breaking down organizational barriers to foster a safety culture.
-
Consensus Standards
- Written standards developed by expert groups to ensure conformity in daily lab operations.
- Major organizations:
- ISO (International Organization for Standardization)
- CLSI (Clinical Laboratory Standards Institute)
- Also referenced: College of American Pathologists (CAP) and Joint Commission International (JCI).
- These standards identify specific risks and provide quality management systems adaptable to each lab’s context.
- Labs often customize their own systems by integrating elements from multiple standards.
-
Failure Mode and Effects Analysis (FMEA) and Root Cause Analysis (RCA)
- FMEA: Proactive, preventive tool to anticipate failures before they occur.
- Multidisciplinary team evaluates each process step.
- Prioritizes failures by severity, frequency, and detectability.
- Aims to eliminate or mitigate risks.
- RCA: Reactive tool used after an incident to find root causes.
- Structured investigation to understand what happened, why, and how to prevent recurrence.
- Focuses on system problems, not individual blame.
- FMEA: Proactive, preventive tool to anticipate failures before they occur.
-
Monitoring
- Continuous evaluation of operational performance.
- Detects deviations and verifies effectiveness of improvements.
- Based on social psychology concepts like social facilitation and the Hawthorne effect.
- Monitoring is complementary, not a standalone improvement method.
- Example: Running control samples before patient samples to ensure system control.
2. Specific Risks to Quality and Patient Safety in Clinical Laboratories
- Automation and training reduce but do not eliminate errors.
- Identifying and managing risks is critical due to the complex interactions between labs, patients, and healthcare providers.
- Quality and safety risks must be measurable, reproducible, valid, and economically feasible.
-
Risks are categorized into four groups:
-
Pre-analytical Stage
- Patient and sample identification.
- Communication of orders.
- Sample collection and handling.
- Appropriateness of medical requests.
-
Analytical Stage
- Risks with new methodologies.
- Continuous quality management of tests.
- Use of reference ranges and reference laboratories.
-
Post-analytical Stage
- Reporting of results.
- Admission of moderate cases.
- Interpretation and correction of results.
-
General Laboratory Risks
- Personnel (human capital).
- Information management.
- Result delivery times.
- Laboratory organization.
-
-
Patient and Sample Identification
- Critical risk area; errors here can severely impact patient safety.
- National safety objectives (American College of Pathologists):
- Improve patient and sample identification at all stages.
- Improve communication of critical values.
- Improve error identification, communication, and correction.
- Improve coordination of lab’s role in hospital patient safety.
- Use at least two patient identifiers (not room number).
- Misidentification includes wrong patient or sample mix-ups.
- Underreporting of errors is common; about 35% of errors are caught before results delivery.
- Error detection methods include:
- Checking for mismatched labels or orders.
- Verifying sample receipt against requests.
- Using delta checks (comparing current results with previous ones).
- Feedback from healthcare providers or other labs.
- Control measures:
- Constant monitoring.
- Staff training.
- Redundancy in active patient identification.
-
Sample Collection and Handling
- Samples must be collected in appropriate containers, at correct times, and under proper conditions.
- Samples must be free of hemolysis, clots, and transported promptly.
- Labs must define rejection criteria and monitor transport conditions.
- Responsibility for collection may lie with lab or healthcare providers, but lab must provide standards and training.
-
Appropriate Medical Request
- Ordering the correct test is the first step in the lab’s value chain.
- Promoting responsible test ordering is essential to quality management.
- Ensures resources are used effectively and unnecessary testing is avoided.
