Abstract

BACKGROUND:

Warfarin therapy in pediatric patients can be difficult to manage with bleeding as a primary adverse event. Therapy initiation can be difficult as doses to achieve therapeutic outcomes are being determined. Evaluation of readmission for bleeding in pediatric patients discharged on warfarin therapy may be useful to prevent adverse events.

METHODS:

The Pediatric Health Information System (PHIS) was queried to identify all patients <19 years of age who were discharged from a pediatric hospital on warfarin therapy. Patients who were readmitted with bleeding in the first 30 days after discharge were identified and patient variables, hospital stay variables, and medications at discharge were identified. Univariate and multivariate analysis was performed to identify independent risk factors for bleeding readmission.

RESULTS:

A total of 4,883 patients met study criteria (56% male, mean age 10.1 + 5.9 years). The two most common indications for warfarin therapy were cardiac valve replacement (23.6%) and Fontan procedure (19.5%). Ninety-seven patients (1.99%) were readmitted with bleeding within 30 days of discharge [median time 9 days (IQR 5-16 days)]. Multivariate analysis identified Asian race (OR 4.0, P < 0.01); mitral valve replacement (OR 2.5, P < 0.01); escitalopram at discharge (OR 4.2, P = 0.02); levofloxacin at discharge (OR 8.3, P < 0.01); lansoprazole at discharge (OR 1.7, P = 0.047); and length of stay (OR 1.01, P = 0.047) as significant for bleeding readmission.

CONCLUSION:

Pediatric patients discharged on warfarin may be readmitted for bleeding within 30 days if risk factors are present. Risk factors include patient genetic profile, drug interactions, and indications with higher goal INR values.
