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 assesses how the project addressed PCORI’s Methodology Standards. During peer review, experts read a draft report of the research and provide comments about the report. These experts may include a scientist focused on the research topic, a specialist in research methods, a patient or caregiver, and a healthcare professional. These reviewers cannot 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 descriptions of the conduct of the study or to clarify the connection between results and conclusions. Sometimes, awardees revise their draft reports twice or more to address all of the reviewers’ comments. 

Peer reviewers commented and the researchers made changes or provided responses. Those comments and responses included the following:

  • The reviewers asked for more information about the sampling strategy for the national survey component of the study given the very high response rate, which is unusual for such surveys. The researchers explained that they used a nationally representative survey panel, where members received compensation for the surveys they completed.
  • The reviewers asked for more explanation of the proposed mediation analyses in the study. The researchers explained that conceptually, they hypothesized and sought to investigate whether the effect of perceived discrimination on patient-reported quality of medical care was mediated by the therapeutic relationship between clinician and patient. The researchers acknowledged that they could not fully assess the mediational hypothesis because the timing of data collection for all three constructs did not allow for the researchers to test causation. Instead, the researchers used established methods for testing relationships between such constructs in cross-sectional data.

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
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
