Putting Evidence Into Practice (PEP)
PEP Rating System Overview
ONS PEP resources are designed to provide evidence-based interventions for patient care and teaching. PEP topic teams of nurse scientists, advanced practice nurses, and staff nurses summarize and synthesize the available evidence in PEP topic areas. These resources can be used to plan individual patient care, patient education, nursing education, quality improvement, and research. If you have a question about how to apply these PEP topics to your practice, ask a nurse on ONS staff at firstname.lastname@example.org.
Before you get started, here's a brief overview of PEP terminology.
- Topics are patient-centered outcomes, such as symptoms, that are selected by a survey of ONS members and determination of availability of evidence in the topic.
PEP evidence syntheses answer the question of what interventions are effective in preventing or treating the outcome of interest. Topic teams categorize the interventions by consensus application of the ONS PEP Classification Schema into the categories outlined here.
Recommended for Practice
Interventions for which effectiveness has been demonstrated by strong evidence from rigorously designed studies, meta-analysis, or systematic reviews and for which expectation of harm is small compared to the benefits
Likely to Be Effective
Interventions for which effectiveness has been demonstrated from a single rigorously conducted controlled trial, consistent supportive evidence from well-designed controlled trials using small samples, or guidelines developed from evidence and supported by expert opinion
Benefits Balanced With Harm
Interventions for which clinicians and patients should weigh the beneficial and harmful effects according to individual circumstances and priorities
Effectiveness Not Established
Interventions for which insufficient or conflicting data or data of inadequate quality currently exist, with no clear indication of harm
Interventions for which lack of effectiveness has been demonstrated by negative evidence from a single rigorously conducted controlled trial, consistent negative evidence from well-designed controlled trials using small samples, or guidelines developed from evidence and supported by expert opinion
Not Recommended for Practice
Interventions for which lack of effectiveness or harmfulness has been demonstrated by strong evidence from rigorously conducted studies, meta-analyses, or systematic reviews, or interventions where the costs, burden, or harm associated with the intervention exceed anticipated benefit
Low-risk interventions that are consistent with sound clinical practice, suggested by an expert in a peer reviewed publication, and for which limited evidence exists (An expert is an individual who has published peer reviewed material in the domain of interest.)
