Perceived barriers and marital status explained 21.7% of the variance in warfarin refill adherence (p<0.001), while barriers and living conditions explained 33.2% of self-reported noncompliance.

What are the predictors of noncompliance with warfarin therapy in an outpatient anticoagulation clinic?
p-value: p=<0.001
Perceived barriers, marital status, and living arrangements are significant predictors of warfarin noncompliance in low-income outpatients, supporting the use of refill adherence and self-report as valid compliance measures.
Orensky et al. (2005) conducted a cross-sectional in Warfarin therapy / Anticoagulation (n=75). Patient demographics and beliefs (perceived barriers, marital status, living arrangements) was evaluated on Variance in refill adherence and self-reported noncompliance (p=<0.001). Perceived barriers and marital status explained 21.7% of the variance in warfarin refill adherence (p<0.001), while barriers and living conditions explained 33.2% of self-reported noncompliance.
