Number Needed to Benefit From Information (NNBI): Proposal From a Mixed Methods Research Study With Practicing Family Physicians
Pierre Pluye , and colleagues
Background Electronic resources help physicians find answers to clinical questions, but the wealth of information available to guide primary care practice is not used to its full potential. In this study, researchers describe a new concept about the impact of information gleaned from electronic knowledge resources.
What This Study Found The "number needed to benefit from information" (NNBI) suggests how frequently patients may benefit when their physicians search for information in electronic knowledge resources. The NNBI will vary depending on the type of electronic resource and the clinician's characteristics, such as information seeking skills, knowledge, and behavior in specific clinical situations.
Implications
- This construct might be useful in experimental research to compare resources, identify kinds of clinical questions difficult to answer, and measure benefits of specific searches for information.
