Development of an interview-based warfarin nomogram predicting the time spent in the therapeutic INR range: A cost-effective, and non-invasive strategy building from a cross sectional study in a low resource setting

A cross-sectional study was conducted to predict time in therapeutic range (TTR) using clinical history, examination, and socioeconomic data. Study included warfarin-receiving patients from outpatient-clinic. In 203 patients studied, mean warfarin start-dose was 2.55 mg/day and maintenance-dose/week was 30.79 mg. Body mass index (BMI) (p ¼ 0.03), warfarin maintenance dose/day (p ¼ 0.02), and comorbidity presence (p ¼ 0.04) were significantly associated with TTR. Occupation (p ¼ 0.53), income (p ¼ 0.83), education (p ¼ 0.55), and socioeconomic score (p ¼ 0.73) showed non-significant association with TTR. A TTR predicting nomogram was built from clinical history and examination findings.
