What is the difference between qualitative and quantitative risk assessment methods in healthcare, with examples?

• A. Qualitative uses descriptive judgments (hazard screening); quantitative uses numeric scores (likelihood/consequence matrices)
• B. Qualitative uses numerical scoring; quantitative uses opinions
• C. Qualitative is for marketing; quantitative for clinical
• D. Qualitative ignores data; quantitative uses data only

Answer: (B)

Qualitative risk assessment in healthcare relies on descriptive judgments and expert opinions to identify and prioritize risks without converting everything to numbers. Quantitative risk assessment uses numerical data and calculations to estimate how likely a risk is and how severe its consequences could be, producing numeric risk scores or probabilities. For example, qualitative methods might use hazard screening with checklists and narrative descriptions to flag safety concerns and categorize risk as high, medium, or low based on context and expert input. Quantitative methods might assign numerical probabilities and severity scores, use risk matrices to produce a numeric risk value, or apply statistical models or simulations to estimate overall risk. In healthcare, you might see qualitative approaches in safety review discussions, and quantitative approaches in scoring systems like APACHE II for patient severity or in infection risk analyses that produce concrete numeric estimates. Regarding the statement in the options, the accurate difference is that qualitative relies on descriptive judgments, while quantitative relies on numerical data and calculations, not the other way around.
