Background: The Joint Commission Venous Thrombo - embolism (VTE) National Hospital Inpatient Quality Measure VTE-5 outlines four criteria for discharge patient education when starting anticoagulation (usually, warfarin) therapy. The criteria do not specify content regarding patient recognition of potentially dangerous warfarin-related scenarios. A study was conducted to investigate how well patients assess the risks and consequences of potential warfarin-related safety threats. Methods: From an adult population on long-term warfarin, 480 patients were randomly selected for a telephone-based survey. Warfarin-knowledge questions were drawn from a previous survey; warfarin-associated risk scenarios were developed via focus interviews. Expert anticoagulation pharmacists categorized each scenario as urgent, moderately urgent, or not urgent, as did survey participants. Results: For the 184 patients (38% completion rate), the mean knowledge score was 69% (standard deviation [SD], 0.20). Overall classification accuracy of situational urgency was 59% (95% confidence interval [CI], 57.3%-60.3%). Respondents overestimated non-urgent-severity situations 23% of the time (95% CI, 20.8%-24.7%), while underestimating urgent-severity situations 21% of the time (95% CI, 19.0%-23.9%). A significant percentage of patients failed to recognize the urgency of stroke symptoms (for example, loss of vision), the risk of bleeding after incidental head trauma, or medication mismanagement. Conclusions: Despite fair factual warfarin knowledge, participants did not appear to recognize well the clinical severity of warfarin-associated scenarios. Warfarin education programs should incorporate patient-centered strategies to teach recognition of high-risk situations that compromise patient safety.
