The Home INR Study (THINRS)
“THINRS has demonstrated that [self-testing meters] are able to deliver clinical outcomes every bit as good as those whose tests are performed in hospital or clinical laboratories. THINRS has also demonstrated that a high percentage of patients (by themselves or with care providers such as family members) are able to successfully learn how to perform home INR testing and are able to maintain that capability over time.”1
Noting that the control group in this study was very high-quality clinic care, which is not the norm, and that home INR testing was equally as good as this gold standard, the authors believe the results of this study “have the potential for a major clinical impact.”
