Future Project Development
Future areas for quality improvement project development include expanding project criteria to include patients taking warfarin for VTE. Eighty-nine of 137 patients (65%) who were deemed ineligible to switch to DOAC therapy were excluded due to a diagnosis of VTE. There are existing VA/Department of Defense Criteria for Use for DOAC use in VTE recommendations. Straightforward modification of the screening tool could include this patient group and may be especially useful for patients on indefinite warfarin therapy for recurrent VTE who have poor TTR report results.6
Given the number of confounding factors caused by unforeseen changes to the Anticoagulation Clinic workflow, use of the DOAC screening tool was placed on hold at the conclusion of data collection. This limited the ability to analyze encounter data in the months following project conclusion. Future plans include reimplementation of the screening tool with minor adjustments to include patients on warfarin for VTE and patients with a TTR report results above 60%.
Conclusion
This quality improvement project sought to determine the impact of a screening tool on effecting Anticoagulation Clinic encounter metrics. Results of this project show that the screening tool was unsuccessful in reducing the number of overall clinic encounters. Some promise was shown when evaluating clinic encounters for patients who switched anticoagulation therapies. Numerous confounding factors may have contributed to these results.
