A safe way to save?

In the department of pointless research…

Canadian researchers are studying the effects of extending the INR testing cycle from 1 to 3 months.  They followed ~ 125 patients in each group and determined that the percentage of time in the therapeutic range was similar.  Thankfully, there is no question of widespread adoption of this monitoring schedule (at least for now).

Schulman and colleagues recommend further study before widespread adoption of extended monitoring intervals in clinical practice, adding that this single-center study was “not a true evaluation” of INR monitoring and dosing assessment every 12 weeks because patients assigned to 12-week assessment had their blood drawn every four weeks and telephone contact with anticoagulation staff to remind them of important factors for INR instability.
