Monitor Trial Spotlighted in Prominent Blog
Aaron Carroll of the New York Times' "The Upshot" blog — who moderated a 2018 PCORI Annual Meeting plenary session about balancing benefits and potential harms of different treatment options — discussed this study's finding that routine glucose monitoring may be unnecessary for people with Type 2 diabetes who are not on insulin. Study Principal Investigator Katrina Donahue, MD, MPH, was a presenter/panelist in that session.

Blood Sugar Testing to Manage Type 2 Diabetes in Patients Who Don't Need Insulin
It’s important for people with type 2 diabetes to keep their blood sugar at a healthy level. Many patients check their blood sugar at home each day. But checking your blood sugar daily may not help you to manage your type 2 diabetes. This study found that people with type 2 diabetes who don’t use insulin did not benefit from daily self-testing.

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

  • Adding more information about what the outcomes of the study were designed to measure and what difference in results between groups would be considered clinically meaningful
  • Expanding the text in places to demonstrate adherence to PCORI Methodology Standards
  • Providing examples of the tailored messages sent to patients who were being counseled about diabetes management without needing to test their blood glucose
  • Adding a discussion of possible reasons for the failure to sustain significant improvements in glycemic control seen in the intervention group at six months
  • Providing the context for their exploratory analyses of the association between hemoglobin A1c and compliance with self-monitoring of blood glucose

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
