Summary

This study looked at 31 elderly nursing home residents taking blood thinners (vitamin K antagonists) to see if a simple finger-prick test (capillary INR) gives the same results as a standard blood draw (venous INR) for making treatment decisions. Over 6 months, researchers compared the two methods to check if they agreed on whether to adjust medication. The goal was to see if finger-prick testing could be a reliable, less invasive option for monitoring blood thinning in this frail population.
