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 clinical@ons.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

    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

    Effectiveness Unlikely

    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

    Expert Opinion

    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.)
