Evaluating the safety and effectiveness of new drugs.
Prescribers seek to provide their patients with access to the latest innovations in medicine to maximize their health status. When a new drug comes to market, it often has not been as widely tested as other available therapies, and its effectiveness and safety cannot be fully evaluated. To address this problem, physicians can use the STEPS (Safety, Tolerability, Effectiveness, Price, and Simplicity) mnemonic to provide an analytic framework for making better decisions about a new drug's appropriate place in therapy. A key element is to base this evaluation on patient-oriented evidence rather than accept disease-oriented evidence (which may be misleading), while avoiding inappropriate reliance on studies that report only noninferiority results or relative risk reductions. The primary question to ask for each new drug prescribing decision is, "Is there good evidence that this new drug is likely to make my patient live longer or better compared with the available alternatives?"
