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 found the final research report to be exceptionally clear and well written, with few requested revisions.
- The reviewers questioned how the researchers chose their control group of patients from the available Medicare data. The reviewers noted that the patients were not eligible to be in the control group if they were readmitted into a hospital within 90 days after hospital discharge, creating a selection bias leading to significant differences between the case and control patients. The researchers explained that they used the same definitions for their comparison groups as the Center for Medicare and Medicaid Services, since the study used the same models for their analyses. The researchers did note in the discussion section that this difference between the comparison groups exaggerated the differences between the case and control groups.
