Abstract

A prior single center randomized trial suggested that patients with stable INR values could safely receive INR testing as infrequently as every 12 weeks. To test the implementation success of an extended INR testing interval for stable warfarin patients in a practice-based, multi-center collaborative of anticoagulation clinics. At six anticoagulation clinics, patients were identified as being eligible for extended INR testing based on prior INR value stability and minimal warfarin dose changes between 2014 and 2016. We assessed the frequency with which anticoagulation clinic providers recommended an extended INR testing interval (>5 weeks) to eligible patients. We also explored safety outcomes for eligible patients, including next INR values, bleeding events, and emergency department visits. At least one eligible period for extended INR testing was identified in 890/3362 (26.5%) warfarin-treated patients. Overall, the use of extended INR testing in eligible patients increased from 41.8% in 2014/Q1 to 69.3% in 2016/Q4. The number of subsequent out-of-range next INR values were similar between eligible patients who did and did not receive an extended INR testing interval (27.3% vs. 28.4%, respectively). The number of major bleeding events were not different between the two groups, but rates of clinically relevant non-major bleeding (0.02/100-patient-years vs. 0.09/100-patient-years) and emergency department visits (0.07/100-patient-years vs. 0.19/100-patient-years) were lower for eligible patients with extended vs. non-extended INR testing intervals. Extended INR testing for stable warfarin patients can be successfully and safely implemented in diverse, practice-based anticoagulation clinic settings. This article is protected by copyright.

Attention Score in Context

This research output has an Altmetric Attention Score of 73. This is our high-level measure of the quality and quantity of online attention that it has received. This Attention Score, as well as the ranking and number of research outputs shown below, was calculated when the research output was last mentioned on 10 August 2018.
All research outputs
#176,570
of 11,623,310 outputs
Outputs from Journal of Thrombosis & Haemostasis
#8
of 1,965 outputs
Outputs of similar age
#8,973
of 246,822 outputs
Outputs of similar age from Journal of Thrombosis & Haemostasis
#2
of 49 outputs
Altmetric has tracked 11,623,310 research outputs across all sources so far. Compared to these this one has done particularly well and is in the 98th percentile: it's in the top 5% of all research outputs ever tracked by Altmetric.
So far Altmetric has tracked 1,965 research outputs from this source. They typically receive a little more attention than average, with a mean Attention Score of 5.5. This one has done particularly well, scoring higher than 99% of its peers.
Older research outputs will score higher simply because they've had more time to accumulate mentions. To account for age we can compare this Altmetric Attention Score to the 246,822 tracked outputs that were published within six weeks on either side of this one in any source. This one has done particularly well, scoring higher than 96% of its contemporaries.
We're also able to compare this research output to 49 others from the same source and published within six weeks on either side of this one. This one has done particularly well, scoring higher than 95% of its contemporaries.
