The key goal of this survey is to estimate the severity of patient harm associated with an incorrect reported result for a selected panel of common analytes tested in a medical laboratory. The purpose is to use your medical lab knowledge to establish an international consensual classification which can be used to improve patient risk management.

Question Title

* 1. How would you rate the severity of patient harm if a clinician would interpret incorrect reported results from these analytes?

N.B: As we understand that an erroneous result could generate different severity of harm depending on clinical context and error depth we advise you to consider the most unfavorable situation that can occur in your lab activity.
  • Negligible - inconvenience or temporary discomfort
  • Minor - temporary injury or impairment not requiring medical intervention
  • Serious - injury or impairment requiring medical intervention
  • Critical - permanent impairment or life-threatening injury
  • Catastrophic - patient death



The suggested analytes are categorized as follows:
- Clinical Chemistry
- Endocrinology
- Tumor Markers
- Hematology
- Blood Coagulation
- Pharmacology / Toxicology
- Virology
- HIL Indices
