Encouraging Colorectal Cancer Screening among Hispanics
One of the more than 100 PCORI-funded studies that are addressing disparities in health and healthcare takes on colorectal cancer, for which early detection save lives: 90 percent of people whose colorectal cancer is early stage at diagnosis live for at least five years, but only 14 percent of people whose cancer has spread to other parts of the body survive that long. Screening rates differ between groups of people, with Hispanics/Latinos falling behind whites. In this blog post, two members of a research team share insights and results from tests of a method to increase screening among Hispanics.


Increasing Colon Cancer Screening Rates in the Hispanic Population (right)
Hear more about how this study compared the effectiveness of two communication approaches by the Lehigh Valley Health Network in Pennsylvania to increase the colon cancer screening rate among Hispanics.

Decision Support and Navigation
Study principal investigator Ronald E. Myers, PhD says that decision support and navigation—an approach studied through his study—has potential to change practice if a centralized process is adopted and implemented by health systems.

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:

  • Reviewers expressed concern about the substantial number of patients in the study source population who did not participate in the research and therefore, whether the patients who agreed to participate were truly representative of the source population. The researchers explained in the report that they compared characteristics of patients included in the study to those of the source population. The comparisons indicated that patients included in the study were more likely to be under 60 years old and to come from certain primary care practices than those in the source population.
  • Reviewers noted that the report did not sufficiently discuss the low rates of stool blood test rescreening, despite a much higher rate of initial screenings in the navigator intervention group compared to the standard practice group. The researchers hypothesized in the report’s discussion that the low rate of rescreening in the intervention group was due to the lack of additional intervention contacts, which reduced motivation in this group. The investigators hypothesized further that comparison patients, however, had to be more self-motivated from the beginning to complete the stool blood test initially and therefore, probably had a higher rate of motivation to follow the guidelines for annual screening.

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
Funding Opportunity Type
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
