Study Notes
Diagnostic Errors
- Inaccurate measurements can lead to two types of errors:
- False negative error: when a patient is diagnosed as free of a disease they actually have
- False positive error: when a patient is diagnosed with a disease they do not have
Reducing Diagnostic Errors
- Ways to reduce errors and uncertainties:
- Researching causes of misleading laboratory test values
- Repeating measurements
- Care in taking measurements
- Developing new clinical tests
- Improving instrumentation
- Using reliable instruments
- Calibrating instruments relative to standards or already calibrated instruments
Medical Measurements
- Measurements needed before treatment:
- Routine measurements: • Body temperature • Pulse rate • Blood pressure • Body weight
- Additional required tests based on the patient's case, including: • Laboratory investigations • Body signals investigations • Machinery measuring instruments
