risk-benefit analysis(redirected from Risk to benefit ratio)
Examination of the potential positive and negative results of undertaking a specific therapeutic course of action. For example, a man with a slowly growing, localized prostate cancer might want to know whether it is better to undergo surgery (and risk urinary incontinence and erectile dysfunction) or to manage his disease conservatively (and risk the spread of the disease). Factors influencing his decision include: 1 financial cost of the operation; 2 likelihood of disease spread; 3 likelihood of complications with or without the operation; 4 life expectancy; 5 overall state of health; and 6 alternative treatments for his disease.
