Quality

Quality, in pathology, has got a lot of attention lately because there have been high profile screw-ups that lead to significant harm.[1]
Analysis
Quality issues are examined a number of different ways, e.g. root cause analysis, failure mode and effects analysis (FMEA).
A common way to break down error analysis is:
| Errors in pathology | |||||||||||||||||||||||||||||||||
| Pre-analytical errors | Analytical errors | Post-analytical errors | |||||||||||||||||||||||||||||||
Error reduction
Various strategies can be employed:[2]
- Training of staff - on error handling.
- Computer order entry.
- Avoid duplication fatigue.
- Quick correlation with several identifying features.
- Full name, sex, date of birth -- these all appear when one opens a case.
- Barcode use.
- Avoid transcription errors.
- Clinical information entry required.
- Allow correlation with test.
- The interpretation may differ if the history says "screening coloscopy" versus "large cecal mass, anemia and weight loss".
- Allow correlation with test.
Other strategies:
- Statistical process control.
Sources of error
- "Human error".
- Training.
- Work flow.
- Process gaps.
- Process control.
- Lack of redundancy.
Biopsy size
Very small tissue fragments are associated with a decreased diagnostic yield and an increased diagnostic uncertainty.
