Peer-Review Summary

Peer review of PCORI-funded research helps make sure the report presents complete, balanced, and useful information about the research. It also confirms that the research has followed PCORI’s Methodology Standards. During peer review, experts who were not members of the research team read a draft report of the research. These experts may include a scientist focused on the research topic, a specialist in research methods, a patient or caregiver, and a healthcare professional. Reviewers do not have conflicts of interest with the study.

The peer reviewers point out where the draft report may need revision. For example, they may suggest ways to improve how the research team analyzed its results or reported its conclusions. Learn more about PCORI’s peer-review process here.

In response to peer review, the PI made changes including

  • Explaining that the study was conducted in three phases, so time was the variable that determined which patients were exposed to the shared decision-making tool and coaching interventions.
  • Clarifying that the primary outcome of the study was the impact of the studied tool on patient-physician shared decision making about stent selection in percutaneous coronary intervention. The researchers explained that the analysis of stent choice concordance with the patient’s stent preference was a secondary outcome, and therefore the results of these analyses were described in less detail.
  • Revising the results to explain that clinician interviews were conducted after implementation of the shared decision-making tool, and why these interviews were only conducted at one site. The researchers also acknowledged in their Limitations section that more physician follow-up interviews about stent selection and use of the shared decision-making tool would have been useful to help understand the study results.
  • Discussing in the Limitations section the lack of available nurse decision coaches and physician engagement, and how these may have affected the study outcomes. Although better physician engagement might have led to positive larger effect of the decision aids, the researchers noted in their response to reviewers that better engagement would not be a realistic expectation in most cardiology practices.
  • Responding to reviewer concerns about problems with intervention implementation and uptake at the clinical sites by noting that these problems were part of the real-world experience of working in these clinical settings and would need to be overcome for improved implementation of a shared decision-making tool.

Award Type
Health Conditions Health Conditions These are the broad terms we use to categorize our funded research studies; specific diseases or conditions are included within the appropriate larger category. Note: not all of our funded projects focus on a single disease or condition; some touch on multiple diseases or conditions, research methods, or broader health system interventions. Such projects won’t be listed by a primary disease/condition and so won’t appear if you use this filter tool to find them. View Glossary
Populations Populations PCORI is interested in research that seeks to better understand how different clinical and health system options work for different people. These populations are frequently studied in our portfolio or identified as being of interest by our stakeholders. View Glossary
Intervention Strategy Intervention Strategies PCORI funds comparative clinical effectiveness research (CER) studies that compare two or more options or approaches to health care, or that compare different ways of delivering or receiving care. View Glossary
State State The state where the project originates, or where the primary institution or organization is located. View Glossary
