Document Summary
Risk markers = associated with a bad outcome. Risk of disease = cvd, mi, strokes, fractures. Risk factor = variable associated with an increased risk of disease. Figuring out the risks vs. benefit of treatment. Ballpark risk estimate = framingham, qrisk, frax, cha2ds2-vasc. Ballpark benefit estimate = rct data: use the absolute benefit if your patient is similar to those in the studies, or, use the relative benefit and apply it to the baseline risk. Use percentages or natural frequencies (numerator/denominator) verify that the patient understands what % means. Use incremental risk format with icon arrays in the same array. Avoid use of nnts does(cid:374)"t tell the patie(cid:374)t a(cid:271)out their risk of a cv e(cid:448)e(cid:374)t, just tells you the (cid:271)e(cid:374)efit. If you use relative risks, always include baseline risks. Cvd = cardiovascular disease = chd + cerebrovascular. Chd = coronary heart disease = fatal and non-fatal mis and sometimes angina.
