A patient might ask the clinician: "How long will it take me to get back to sport?" or "How long until I'm feeling back to myself again?". These questions ask the clinician to make a prognosis - to predict the future.
Often we rely on our clinical experience or intuition to answer with a prognosis. Sometimes we might know some prognostic factors, which can give us some big-picture ideas, but they're rarely enough to give the full picture.
Today physiotherapists and researchers Daniel Feller and Dr Alessandro Chiarotto (Erasmus Medical Centre, Rotterdam, The Netherlands) explain prognostic prediction models: what they are, how they might help in practice, and what to look for when you're deciding whether a tool like the STarT Back is suitable for your practice.
