RT Journal A1 Gill TM T1 THe central role of prognosis in clinical decision making JF JAMA JO JAMA YR 2012 FD January 11 VO 307 IS 2 SP 199 OP 200 DO 10.1001/jama.2011.1992 UL http://dx.doi.org/10.1001/jama.2011.1992 AB In clinical practice and training, estimating prognosis—the probability of an individual developing a particular outcome over a specific period of time—typically receives less attention than diagnosing and treating disease. Yet many clinical decisions are not fully informed unless the patient's prognosis is considered. Because of competing chronic conditions and diminished life expectancy, careful consideration of prognosis is particularly important for clinical decision making in older patients. In a systematic review in this issue of JAMA, Yourman and colleagues1 evaluated 16 validated, non–disease-specific indices that predict mortality for older persons. The authors rigorously assessed each index for generalizability, accuracy, and potential bias. They concluded that none of the indices is ready for widespread use in clinical practice. Even if 1 or more of these prognostic indices had passed or exceeded the specified quality benchmarks,2- 4 their clinical utility would be uncertain.
