Clinical Decision Threshold

Shrink Definition

A clinical decision threshold is the point at which the probability of benefit, harm, or disease becomes sufficient to justify a particular clinical action, such as testing, treatment, referral, or observation. Decision thresholds vary depending on the seriousness of the condition, potential benefits, potential harms, patient values, and the quality of available evidence.

Medicine often asks, "Do we have enough evidence to act?"
